Technical Field

The subject matter disclosed herein relates generally to sensors for articles of footwear.

Background

Articles of footwear generally include two primary elements: an upper and a sole structure. The upper is generally formed from a plurality of material elements (e.g., textiles, polymer sheets, foam layers, leather, synthetic leather) that are stitched or adhesively bonded together to form a void on the interior of the footwear for comfortably and securely receiving a foot. More particularly, the upper forms a structure that extends over instep and toe areas of the foot, along medial and lateral sides of the foot, and around a heel area of the foot. The upper may also incorporate a lacing system to adjust the fit (fit) of the footwear, as well as to allow the foot to enter and remove the foot from the void within the upper. Likewise, some articles of apparel may include various closure systems for adjusting the fit of the apparel.

Detailed Description

Example methods and systems relate to sensors for an article of footwear. Examples merely typify possible variations. Unless explicitly stated otherwise, components and functions are optional and may be combined or subdivided, and operations may vary in sequence or be combined or subdivided. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the example embodiments. It will be apparent, however, to one skilled in the art that the present subject matter may be practiced without these specific details.

The following discussion and accompanying figures disclose an article of footwear and a method of assembling an article of footwear. Concepts disclosed herein with respect to footwear may be applied to a variety of athletic footwear styles, including running shoes, basketball shoes, soccer shoes, baseball shoes, football shoes, and golf shoes, for example. Accordingly, the concepts disclosed herein are applicable to a variety of footwear types.

To aid and clarify the subsequent description of the various embodiments, various terms are defined herein. The following definitions apply throughout this specification (including the claims) unless otherwise indicated. Directional adjectives are used throughout this detailed description corresponding to the illustrated embodiments for consistency and convenience.

The term "longitudinal" as used throughout this detailed description and in the claims refers to a direction extending the length of a component. For example, a longitudinal direction of the article of footwear extends between a forefoot region and a heel region of the article of footwear. The term "forward" is used to refer to the general direction in which the toes of the foot point, and the term "rearward" is used to refer to the opposite direction, i.e., the direction in which the heel of the foot faces.

The term "lateral direction" as used throughout this detailed description and in the claims refers to a direction from one side to the other side of the width of the extension member. In other words, the lateral direction may extend between a medial side and a lateral side of the article of footwear, where the lateral side of the article of footwear is the surface that faces away from the other foot and the medial side is the surface that faces toward the other foot.

As used in this specification and in the claims, the term "side" refers to any portion of a component that generally faces in a direction such as an outboard direction, inboard direction, forward direction, or rearward direction as opposed to an upward or downward direction.

The term "vertical" as used throughout this detailed description and in the claims refers to a direction that is substantially perpendicular to both the transverse and longitudinal directions. For example, in the case where the sole is laid flat on the ground, the vertical direction may extend upward from the ground. It should be understood that each of these directional adjectives may be applied to various components of a sole. The term "upward" refers to a vertical direction proceeding away from the ground, while the term "downward" refers to a vertical direction proceeding toward the ground. Similarly, the terms "top," "upper," and other similar terms refer to the portion of an object that is generally furthest from the ground in a vertical direction, while the terms "bottom," "lower," and other similar terms refer to the portion of an object that is generally closest to the ground in a vertical direction.

The "interior" of the shoe refers to the space occupied by the wearer's foot when the shoe is worn. The "medial side" of a panel or other footwear element refers to the face of the panel or element that is oriented toward (or will be oriented toward) the interior of the shoe in the finished shoe. The "lateral side" or "exterior" of an element refers to the face of the element that is oriented away from (or will be oriented away from) the shoe interior in a finished shoe. In some cases, the medial side of an element may have other elements between the medial side and the interior in the finished shoe. Similarly, the lateral side of an element may have other elements between the lateral side and the space outside the finished shoe. Furthermore, the terms "inwardly" and "inwardly" shall refer to a direction toward the interior of the footwear, while the terms "outwardly" and "outwardly" shall refer to a direction toward the exterior of the footwear.

For purposes of this disclosure, the above directional terms, as used with respect to an article of footwear, shall refer to the article of footwear when in an upright position, with the sole facing the ground, that is, as the article of footwear would be positioned when worn by a wearer standing on a generally horizontal surface.

Additionally, for purposes of this disclosure, the term "fixedly attached" shall mean that two components are joined in such a way that the components cannot be easily separated (e.g., without breaking one or both of the components). Exemplary forms of fixed attachment may include joining using permanent adhesives, rivets, sutures, staples, welding or other thermal bonding or other joining techniques. Additionally, the two components may be "fixedly attached" by being integrally formed, for example, in a molding process.

For the purposes of this disclosure, the term "removably attached" or "removably inserted" shall mean that two components or components and elements are joined in such a way that the two components are secured together but can be easily detached from each other. Examples of removable attachment mechanisms may include hook and loop fasteners, friction fit connections, interference fit connections, threaded connectors, cam lock connectors, compression of one material with another, and other such easily detachable connectors.

Referring to fig. 1, an isometric side view of an article of footwear ("article") 100 configured with a tensioning system 150 is depicted. In the current embodiment, article 100 is shown in the form of an athletic shoe (e.g., a running shoe). However, in other embodiments, tensioning system 150 may be used with any other type of footwear, including but not limited to: hiking boots, soccer shoes, football shoes, canvas sports shoes, running shoes, cross-training shoes, soccer shoes, basketball shoes, baseball shoes, and other types of shoes. Further, in some embodiments, article 100 may be configured for use with different types of non-athletic related footwear, including, but not limited to: slippers, sandals, high-heeled footwear, flat-heeled shoes (loafers), and any other type of footwear. As discussed in further detail below, the tensioning system may not be limited to footwear, and in other embodiments, the tensioning system and/or components associated with the tensioning system may be used with various types of apparel, including apparel, athletic equipment, and other types of apparel. In still other embodiments, the tensioning system may be used with an abutment, such as a medical abutment.

As noted above, directional adjectives are employed throughout this detailed description for consistency and convenience. Article 100 may be divided into three general zones along longitudinal axis 180: forefoot region 105, midfoot region 125, and heel region 145. Forefoot region 105 generally includes portions of article 100 corresponding with the toes and the joints connecting the metatarsals with the phalanges. Midfoot region 125 generally includes portions of article 100 corresponding with an arch area of the foot. Heel region 145 generally corresponds with rear portions of the foot, including the calcaneus bone. Forefoot region 105, midfoot region 125, and heel region 145 are not intended to demarcate precise areas of article 100. Rather, forefoot region 105, midfoot region 125, and heel region 145 are intended to represent generally relevant areas of article 100 to aid in the following discussion. Because various features of article 100 extend beyond a region of article 100, the terms forefoot region 105, midfoot region 125, and heel region 145 apply not only to article 100, but also to various features of article 100.

Referring to fig. 1, for reference purposes, lateral axis 190 of article 100, as well as any components associated with article 100, may extend between medial side 165 and lateral side 185 of the foot. Moreover, in some embodiments, longitudinal axis 180 may extend from forefoot region 105 to heel region 145. It should be understood that each of these directional adjectives may also be applied to various components of an article of footwear, such as an upper and/or a sole member. Additionally, vertical axis 170 refers to an axis perpendicular to a horizontal surface defined by longitudinal axis 180 and lateral axis 190.

Article 100 may include upper 102 and sole structure 104. In general, upper 102 may be any type of upper. In particular, upper 102 may have any design, shape, size, and/or color. For example, in embodiments where article 100 is a basketball shoe, upper 102 may be a high top upper (high top upper) shaped to provide high support at the ankle. In embodiments where article 100 is a running shoe, upper 102 may be a low top upper.

As shown in fig. 1, upper 102 may include one or more material elements (e.g., mesh, textiles, foam, leather, and synthetic leather) that may be coupled to define an interior void 118 configured to receive a foot of a wearer. The material elements may be selected and arranged to impart properties such as light weight, durability, breathability, abrasion resistance, flexibility, and comfort. Upper 102 may define an opening 130, and a foot of a wearer may be received into interior void 118 through opening 130.

At least a portion of sole structure 104 may be fixedly attached to upper 102 (e.g., using adhesives, stitching, welding, or other suitable techniques), and may have a configuration that extends between upper 102 and the ground. Sole structure 104 may include provisions for attenuating ground reaction forces (i.e., cushioning and stabilizing the foot during vertical and horizontal loads). In addition, sole structure 104 may be configured to provide traction, impart stability, and control or limit various foot motions, such as pronation, supination, or other motions.

In some embodiments, sole structure 104 may be configured to provide traction for article 100. In addition to providing traction, sole structure 104 may attenuate ground reaction forces when compressed between the foot and the ground during walking, running, or other ambulatory activities. The configuration of sole structure 104 may vary significantly in different embodiments to include a variety of conventional or non-conventional structures. In some cases, the configuration of sole structure 104 may be configured according to one or more types of ground surfaces on which sole structure 104 may be used.

For example, the disclosed concepts may be applicable to footwear configured for use on any of a variety of surfaces, including indoor or outdoor surfaces. The configuration of sole structure 104 may vary based on the properties and conditions of the surface on which article 100 is intended to be used. For example, sole structure 104 may vary depending on whether the surface is hard or soft. In addition, sole structure 104 may be customized for use in wet or dry conditions.

In some embodiments, sole structure 104 may be configured for a particular specialized surface or condition. However, the proposed footwear upper configuration may be applicable to any kind of footwear, such as basketball, soccer, football, and other athletic activities (athletic activities). Accordingly, in some embodiments, sole structure 104 may be configured to provide traction and stability on a hard indoor surface (e.g., hardwood), a soft natural turf surface, or on a hard artificial turf surface. In some embodiments, sole structure 104 may be configured for use on a plurality of different surfaces.

As will be discussed further below, in different embodiments, sole structure 104 may include different components. For example, sole structure 104 may include an outsole, a midsole, a cushioning layer, and/or an insole. Additionally, in some cases, sole structure 104 may include one or more cleat members (clear members) or traction elements configured to increase traction with the ground surface.

In some embodiments, sole structure 104 may include multiple components that may individually or collectively provide several attributes to article 100, such as support, stiffness, flexibility, stability, cushioning, comfort, weight reduction, or other attributes. In some embodiments, sole structure 104 may include an insole/sockliner, midsole 151, and a ground contacting outer sole member ("outsole") 162, where ground contacting outer sole member 162 may have an exposed ground contacting lower surface. However, in some cases, one or more of these components may be omitted. Additionally, in some embodiments, an insole may be disposed in the void defined by upper 102. The insole may extend through each of forefoot region 105, midfoot region 125, and heel region 145 of article 100 and between lateral side 185 and medial side 165 of article 100. The insole may be formed of a deformable (e.g., compressible) material, such as a polyurethane foam or other polymer foam material. Thus, the insole may provide cushioning by virtue of its compressibility and may also conform to the foot to provide comfort, support, and stability.

Midsole 151 may be fixedly attached to a lower region of upper 102, for example, by stitching, adhesive bonding, thermal bonding (such as welding), or other techniques, or may be integral with upper 102. Midsole 151 may be formed from any suitable material having the properties described above, depending on the activity for which article 100 is intended. In some embodiments, midsole 151 may include a foamed polymer material such as Polyurethane (PU), Ethylene Vinyl Acetate (EVA), or any other suitable material that acts to attenuate ground reaction forces as sole structure 104 contacts the ground during walking, running, or other ambulatory activities.

Midsole 151 may extend through each of forefoot region 105, midfoot region 125, and heel region 145 of article 100 and between lateral side 185 and medial side 165 of article 100. In some embodiments, portions of midsole 151 may be exposed around a perimeter of article 100, as shown in fig. 1. In other embodiments, midsole 151 may be completely covered by other elements, such as material layers from upper 102. For example, in some embodiments, midsole 151 and/or other portions of upper 102 may be disposed adjacent a bootie (bootie)114 disposed medial to interior void 118 of article 100. However, other embodiments may not include a bootie.

Further, as shown in fig. 1, in some embodiments, article 100 may include a tongue 172, and tongue 172 may be disposed near or along the throat opening. In some embodiments, tongue 172 may be disposed in or near instep area 110 of article 100. However, in other embodiments, the tongue 172 may be provided along other portions of the article of footwear, or the article may not include a tongue.

Additionally, as described above, in various embodiments, article 100 may include tensioning system 150. Tensioning system 150 may include various components and systems for adjusting the size of opening 130 that opens into interior void 118 and tightens (or loosens) upper 102 around the wearer's foot. Some examples of different tensioning systems that may be used are disclosed in the following publications: U.S. patent publication No. 2014/0070042 to Beers et al, published 3/13 2014 and entitled "Motorized testing systems with Sensors" (U.S. patent application No. 14/014,555 previously filed 8/30 2013) and 8,056,269 to Beers et al, published 11/15 2011 and entitled "Article of footwear with Lighting systems" (U.S. patent publication No. 2009/0272013 previously published 11/5 2009), the contents of which are incorporated herein by reference in their entirety.

Furthermore, embodiments described herein may also include or relate to techniques, concepts, features, elements, methods, and/or components from the following: U.S. patent publication No. 2016/0345679 entitled "An Article Of Footwear And AMethod Of Assembly Of The Article Of Footwear" filed on 28.5.2015; U.S. patent publication No. 2016/0345653 entitled "a Lockout Feature For a Control Device" filed on 28.5.2015; U.S. patent publication No. 2016/0345654 entitled "A Charging System for and article of Footwell" filed on 28.5.2015; U.S. patent publication No. 2016/0345671 entitled "A Sole Plate for an arm of Footwell" filed on 28.5.2015; U.S. patent publication No. 2016/0345655 entitled "A Control Device for an arm of Footwell" filed on 28.5.2015; and U.S. patent application No. 14/944,705 entitled "An Automated testing System For An Article Of Footweer" filed on 1/12/2015, each Of which is incorporated by reference herein in its entirety.

In some embodiments, tensioning system 150 may include one or more laces and a motorized tensioning device. A lace used with article 100 may include any type of lacing material known in the art. Examples of laces that may be used include cables or fibers having a low modulus of elasticity and high tensile strength. The lace may include a single strand of material, or may include multiple strands of material. An exemplary material for the lace is SPECTRATM manufactured by Honeywell of Morris Township NJ, new jersey, although other types of extended chain, high modulus polyethylene fiber materials may be used as the lace. The arrangement of the lace depicted in the figures is intended to be exemplary only, and it should be understood that other embodiments are not limited to a particular configuration of lace elements.

Some embodiments may include one or more compartments, recesses, channels, or other receiving portions disposed in various portions of article 100. For purposes of this disclosure, a compartment refers to a separate or distinct section or portion of article 100. In some embodiments, the compartment may include a sleeve-like region, tunnel, or conduit disposed within article 100, and/or a recess, cavity, pocket, chamber, slot, pocket, or other space configured to receive an object, element, or component. In some embodiments, one or more compartments may be included in article 100 during manufacture of article 100. For example, as will be discussed further below with reference to fig. 9, article 100 may include a sleeve (sleeve) or elastic band disposed along an underside of upper 102. In some embodiments, the elastic band may receive or securely hold the component.

As noted above, article 100 may include other elements in different embodiments. Referring to fig. 1, article 100 includes a bootie 114 disposed within upper 102. In some embodiments, bootie 114 may be removed, separated, or detached from article 100. In one embodiment, the position or placement of bootie 114 may be adjusted within article 100. In some embodiments, bootie 114 or other elements may be moved (or removed) in different embodiments and then reinserted or repositioned into article 100 (i.e., returned to their original arrangement within article 100). This may occur after article 100 is manufactured, as discussed further below. For purposes of the present specification and claims, bootie 114 and/or other such adjustable liner materials or elements (such as a tongue) associated with the disclosed embodiments of article 100 may be referred to as "removable elements.

In one embodiment, bootie 114 may substantially surround or define an interior void 118 in article 100, and may be removed to insert a component into article 100. For example, bootie 114 is pulled or removed from interior void 118 of upper 102. It should be understood that in other embodiments, article 100 may not include bootie 114, or bootie 114 may be configured differently than illustrated herein. In some embodiments, removal of bootie 114 may expose a region within article 100 that is open to one or more compartments or facilitate access to a region within article 100 that is open to one or more compartments. In one embodiment, displacement of bootie 114 and/or other removable elements (e.g., tongue) may be exposed at different areas within interior void 118.

Further, it should be understood that the embodiments described herein with reference to the compartment in fig. 1 and in additional figures may be applicable to articles that do not include a tensioning system. In other words, the method of manufacture in which the article may include compartments and/or the article including such compartments may be used for any type or configuration of article of footwear or apparel.

As described above, some embodiments of article 100 may utilize various kinds of devices to send or provide information regarding the use of article 100 to a motorized tensioning system or lacing system or other mechanism. In various embodiments, the article may include provisions for detecting changes that may occur during use of the article 100. For example, some embodiments may include one or more sensors for providing information to the motorized tensioning system. In fig. 1, one embodiment of a sensor device ("device") 140 is depicted within sole structure 104 of article 100. In some embodiments, the device 140 may provide the current as an input to the control unit. In some cases, for example, the predetermined current may be considered to correspond to a certain pressure or weight. In one embodiment, a pressure sensor may be used under the sole of the shoe of the article to indicate when the user is standing. In another embodiment, the motorized tensioning system can be programmed to automatically loosen the tension of the lace as the user moves from a standing position to a seated position. Such a configuration may be useful for elderly people who may require low tension to promote blood circulation when seated, and high tension for safety when standing. In other embodiments, various features of the motorized tensioning system may be turned on or off, or the tension of the lace adjusted, in response to information from the sensors. In other embodiments, the sensor device may be used to provide information that may determine the activation of an LED or other light source. However, in other embodiments, it should be understood that the use of any sensor may be optional, or the sensors described herein may be used in articles that do not include a motorized tensioning system.

In various embodiments, the types of sensor devices that provide information to the system associated with article 100 may include, but are not limited to: pressure sensors, flexion indicators, strain gauges, gyroscopes and accelerometers in the insole for detecting when the wearer is standing and/or rate of movement. In some embodiments, the sensor information may be used to establish a new target tension instead of or in addition to maintaining the initial tension. For example, a pressure sensor may be used to measure the contact pressure of an upper of an article of footwear against a foot of a wearer and automatically adjust to achieve a desired pressure.

In some embodiments, sensor devices such as gyroscopes and accelerometers may be incorporated into article 100. In some embodiments, for example, accelerometers and/or gyroscopes may be used to detect instantaneous movement and/or positional information that may be used as feedback for adjusting lace tension. These sensors may also be implemented to control the period of sleep/wake up to extend battery life. In some cases, for example, information from these sensors may be used to reduce the lace tension in the system when the user is inactive, and to increase the lace tension during periods when the user is in greater activity.

It is further contemplated that in some embodiments, the user may be provided feedback through motor pulses that produce tactile feedback to the user in the form of vibrations/sounds. Such an arrangement may directly facilitate operation of the tensioning system, or provide tactile feedback to other systems with the motorized tensioning device.

In one embodiment, the device 140 may detect a change in pressure or weight (i.e., force). In some embodiments, device 140 may include various mechanisms or components that may be used to measure current, pressure, or other properties in article 100. In various embodiments, device 140 may detect and measure a relative change in force or applied load, detect and measure a rate of change in force, identify a force threshold, and/or detect a contact and/or touch.

In some embodiments, the sensor device may detect a change in pressure. In various embodiments, the sensors may detect and measure relative changes in force or applied load, detect and measure a rate of change in force, identify a force threshold, and/or detect contact and/or touch. In one embodiment shown in fig. 1, the device 140 includes a force sensitive resistor (referred to herein as "FSR"). In some cases, the FSR may comprise a substantially two-dimensional material. In some embodiments, device 140 may include a piezoelectric material. In other embodiments, the sensors may have different sizes and/or shapes in different embodiments and may be disposed in other areas or portions of article 100 than shown here. In some embodiments, the application of pressure (e.g., of a foot inserted into article 100) may activate a sensor, which in turn may trigger other events, such as automatic lacing.

As depicted in fig. 1, the FSR (here, device 140) may be positioned or inserted along heel region 145 of article 100. In the embodiment of fig. 2, an isometric view of the apparatus 140 is depicted. In general, in some embodiments, device 140 may include at least two films or substrate layers separated by a spacer or adhesive layer. Each layer may be elongated in a substantially horizontal direction. In some embodiments, one or more layers of device 140 may comprise a substantially flat sheet or plate or other two-dimensional material or structure. The term "two-dimensional" as used throughout this detailed description and in the claims refers to any generally flat material exhibiting a length and width that is substantially greater than the thickness of the material. While two-dimensional materials may have smooth or substantially untextured surfaces, some two-dimensional materials may exhibit texture or other surface characteristics, such as, for example, dimples, protrusions, ribs, or various patterns. In other embodiments, the geometry of device 140 may vary, and may include various contours or features associated with portions of the foot (e.g., the instep area of the foot).

In various embodiments, device 140 may include an actuation or conductive region 250 associated with one or more layers. In one embodiment, the force sensing resistor ink (e.g., the "FSR element") is screen printed on or otherwise applied to the first layer. Thus, in some cases, device 140 may include an FSR layer that includes an FSR element. In certain embodiments, the second layer receives or includes a conductive material. For example, in some cases, a series of electrode-interdigitated "fingers" may be formed along the second layer. In one embodiment, the second layer comprises a conductive layer. In one embodiment, the two layers may be assembled with the printed surfaces facing each other, and may be bonded together around the perimeter with a double-sided adhesive spacer. In some embodiments, the device 140 includes a resistor that changes its resistance value according to the degree to which it is pressed or compressed. In some embodiments, one layer may deflect and yield to an applied force, creating a contact area between the FSR element and the circuit. In various embodiments, as the force increases, the contact area also increases and the output becomes more conductive. However, in other embodiments, device 140 may operate in any manner known in the art, wherein the device includes a mechanism wherein the resistance changes upon application of a normal force on the device.

For reference, the apparatus 140 may include different portions. As shown in fig. 2, the device 140 includes an active sensor portion ("active portion") 210 connected to a tail portion 220. In some embodiments, tail portion 220 may include traces. Additionally, in some embodiments, the tail portion 220 may be further connected to the connector portion 230, while in other embodiments, the device 140 may not include the connector portion 230. In one embodiment, the connector portion 230 may include an AMP or amplifier connector having a receptacle (female) end. In some embodiments, the housing protects the contacts of the connector portion 230. In one embodiment, connector portion 230 may be connected to an element or component of an automatic tensioning system (see fig. 1). It should be understood that in other embodiments, the device 140 may include any additional or alternative semiconductor material, conductors, adhesive, graphics or coatings, and connectors.

The active portion 210 may differ in size and shape relative to the tail portion 220. For example, in some embodiments, the active portion 210 may have a different width than the tail portion 220. In fig. 2, the active portion 210 has a sensor width 212 that is greater than a tail width 214 of the tail portion 220. However, in other embodiments, the width of the active portion 210 may vary, with the sensor width 212 being the maximum width associated with the active portion 210 and the tail width 214 being the maximum width associated with the tail portion 220. Further, tail portion 220 includes an elongated portion 221 and an end portion 227 connected along a middle portion 225. In some embodiments, the width associated with the elongated portion 221 is generally narrow relative to the width of the middle portion 225 and may be narrower than the width of the end portions 227.

Thus, it should be understood that in different embodiments, the portions comprising the device 140 may have different sizes and/or shapes. For example, in fig. 2, the active portion 210 has a generally elongated elliptical shape. However, in other embodiments, the size and/or shape of the active portion 210 or the tail portion 220 can be different, including but not limited to rectangular, oblong (oblong), square, circular, elliptical, or other regular or irregular shapes. In some embodiments, the electrically active area associated with active portion 210 may be greater or less than that described herein.

To provide the reader with a better understanding of the embodiments, fig. 3 depicts an exploded view of an embodiment of the apparatus 140. As described above, the device 140 includes a plurality of layers. In the embodiment of fig. 3, device 140 includes a top substrate layer 310, a first adhesive layer 320, and a bottom substrate layer 330. It should be understood that in different embodiments, the top substrate layer 310 may comprise an FSR layer or conductor layer, or another type of FSR substrate layer. Similarly, in some embodiments, the bottom substrate layer 330 may comprise an FSR layer or conductor layer, or another type of FSR substrate layer.

In some embodiments, the first adhesive layer 320 is disposed between the top substrate layer 310 and the bottom substrate layer 330. Additionally, in some embodiments, the device 140 may include a surface or backing that pushes against, such that when a force is applied to the device, support is provided. For example, in some embodiments, a second adhesive layer 340 is also included in device 140. However, it should be understood that other embodiments of the device 140 may include a fewer or greater number of layers. In various embodiments, the substrate layer of device 140 is mounted to a rigid or semi-rigid back surface that includes second adhesive layer 340. Further, in some embodiments, second adhesive layer 340 provides the outermost surface layer of device 140. In FIG. 3, a second adhesive layer 340 is disposed below or adjacent to the bottom substrate layer 330.

In some embodiments, the first adhesive layer 320 may act as a spacer between the top substrate layer 310 and the bottom substrate layer 330. In other words, in some embodiments, the two substrate layers (i.e., the top substrate layer 310 and the bottom substrate layer 330) can be spaced apart using spacer materials of various thicknesses (here, the first adhesive layer 320), in some cases forming an air gap between the two substrate layers. In various embodiments, the first adhesive layer 320 includes or defines the exposed region 350, wherein no spacer material is present in the first adhesive layer 320. In some embodiments, the first adhesive layer 320 comprises a generally narrow or elongated material extending along a perimeter of the device 140, similar to a boundary that corresponds at least in part to a shape of the top substrate layer 310 and/or the bottom substrate layer 330.

By including the exposed region 350, in some embodiments, there may be portions of the top substrate layer 310 and the bottom substrate layer 330 that directly face each other. In FIG. 3, it can be seen that the top outer surface 312 of the top substrate layer 310 faces upward and provides the outermost surface of the device 140. In addition, a top inner surface 314 (the surface opposite the top outer surface 312) of the top substrate layer 310 faces the rest of the device 140. Further, the top inner surface 314 of the top substrate layer 310 may directly face the bottom inner surface 332 of the bottom substrate layer 330 and, in some embodiments, contact the bottom inner surface 332 of the bottom substrate layer 330. Further, in some embodiments, the bottom outer surface 334 of the bottom substrate layer 330 may contact or face the second adhesive layer 340.

In various embodiments, the first adhesive layer 320 may comprise different materials. In one embodiment, the first adhesive layer 320 may include a double-sided adhesive. In various embodiments, it is understood that one or more of the height or thickness of the first adhesive layer 320, the inner diameter or width of the first adhesive layer 320, the open area (here, the exposed area 350) of the first adhesive layer 320, and the thickness of the top substrate layer 310 may mechanically determine the amount of force required to contact the two surfaces, including the top inner surface 314 of the top substrate layer 310 and the bottom inner surface 332 of the bottom substrate layer 330.

Although the first adhesive layer 320 is shown in fig. 3 as being positioned between the top substrate layer 310 and the bottom substrate layer 330, it should be understood that in other embodiments, other materials or mechanisms may be used to provide spacing between the two substrate layers. For example, in some embodiments, a media dot pattern may also be used to space two layers apart, where the frequency or spacing and height of the dots may help determine the amount of force required for activation. In one embodiment, the closer the points are to each other, the greater the force required to activate the sensor. In other embodiments, any other method known in the art for providing spacing between two substrate layers may be used.

Further, in various embodiments, one or more layers of device 140 may include holes or openings formed within the material comprising the layer. For example, in fig. 3, it can be seen that the bottom substrate layer 330 includes a first aperture 336 formed along a portion of the exploded elongated portion 221 of the tail portion 220, and the second adhesive layer 340 includes a second aperture 346 formed along a portion of the exploded elongated portion 221 of the tail portion 220. In different embodiments, the shape of each aperture may vary. In some embodiments, the apertures may have any shape, including but not limited to rectangular, oblong, square, circular, oval, or other regular or irregular shapes. In fig. 3, the first aperture 336 has a generally square or rectangular shape, while the second aperture 346 has a generally rectangular shape. In various embodiments, the bottom substrate layer 330 and the second adhesive layer 340 can be positioned such that the holes are aligned when the device 140 is assembled. In other words, in some embodiments, the first aperture 336 may be disposed such that it overlaps or extends across the opening provided by the second aperture 346. In other embodiments, additional apertures may be formed in any of the top substrate layer 310, the bottom substrate layer 330, the first adhesive layer 320, and/or the second adhesive layer 340. However, in some embodiments, there may not be an aperture in device 140, or any of top substrate layer 310, bottom substrate layer 330, first adhesive layer 320, and/or second adhesive layer 340 may be substantially continuous.

Additionally, in various embodiments, the device 140 may include provisions for covering or protecting portions of the device 140. As will be discussed further below with reference to fig. 9-12, in some embodiments, an elastic membrane (e.g., latex or rubber material) including a cover portion 360 may be incorporated into the device 140 or attached to the device 140. In other embodiments, cover portion 360 may include any other generally resilient and elastic material. As shown in fig. 3, in some embodiments, a cover portion 360 may be disposed between the bottom substrate layer 330 and the second adhesive layer 340. In one embodiment, cover portion 360 is positioned such that when device 140 is assembled, cover portion 360 extends between and covers the openings associated with first aperture 336. However, it should be understood that in other embodiments, the cover portion 360 may be disposed along any other location. Further, in various embodiments, the size of cover portion 360 may be increased or decreased to correspond to the size of any apertures formed in device 140. As will be discussed with reference to fig. 15 and 16, in some embodiments, cover portion 360 may be selectively positioned along an outermost surface of device 140 adjacent second aperture 346 and sized and dimensioned to cover the opening associated with second aperture 346.

In some embodiments, an FSR-type device may include provisions for directing or allowing air to flow from one region of the device to another region of the device. In various embodiments, a vent or other type of conduit may be formed through the device. In one embodiment, the vents may extend from the open active area associated with the active portion 210 and extend down the entire length or only a portion of the tail portion 220. In some cases, the air may be directed to exit into the outside atmosphere. In various embodiments, vents or conduits may help improve pressure equalization with the environment, as well as facilitate uniform loading and unloading of the device. However, as will be described herein, in some embodiments, air may be directed and/or displaced by the device 140 without physically exiting from the interior of the device 140.

In various embodiments, device 140 may include provisions for assisting in the circulation or movement of air or other gaseous fluid through device 140. In some embodiments, a continuous flow path or conduit may be formed in device 140 to help air located within device 140 move through different portions of device 140 as device 140 is actuated and released and returns to a neutral state. In one embodiment, the inclusion of a flow path may improve the repeatability of the sensor device to changes in ambient air pressure and increase the response time of the sensor.

Referring to fig. 4, a top-down view of the device 140 (when assembled) and a cross-sectional view of a portion of the elongated portion 221 are depicted. In the cross-sectional view, top substrate layer 310 is shown as the outermost layer and is disposed directly above first adhesive layer 320 in a direction generally aligned with vertical axis 470. The first adhesive layer 320 is positioned between the top substrate layer 310 and the bottom substrate layer 330. Further, as previously described, the bottom substrate layer 330 is positioned between the first adhesive layer 320 and the second adhesive layer 340. The cross-sectional view also illustrates a first aperture 336 formed in the bottom liner 330 between the first bottom side portion 410 and the second bottom side portion 420, the first aperture 336 extending in a direction generally aligned with the lateral axis 490. Further, a second aperture 346 can be seen formed in the second adhesive layer 340 between the first adhesive side portion 430 and the second adhesive side portion 440, the second aperture 346 extending in a direction generally aligned with the lateral axis 490.

As described above, in some embodiments, the size of the first aperture 336 may be different than the size of the second aperture 346. In fig. 4, the first width 480 of the first aperture 336 is substantially less than the second width 482 of the second aperture 346. In one embodiment, the horizontal cross-sectional surface area associated with the first apertures 336 is less than the horizontal cross-sectional surface area of the second apertures 346. In other embodiments, the width of each aperture may be substantially similar. In one embodiment, the second width 482 may be less than the first width 480. In some embodiments, due to the different size of each aperture, it can be seen that a portion of the bottom outer surface 334 of the bottom substrate layer 330 can provide the outermost surface of the device 140. In other words, while second adhesive layer 340 provides most of the lower outermost surface of device 140, in some embodiments, second aperture 346 may expose a portion of bottom substrate layer 330 from below because second aperture 346 is larger than first aperture 336.

In addition, as previously described, the inclusion of the first adhesive layer 320 provides a space between the two substrate layers, forming a gap or channel 460 having a height substantially similar to the thickness of the first adhesive layer 320. Thus, the channel 460 may be located between the top substrate layer 310 and the bottom substrate layer 330 in association with an exposed area of the first adhesive layer 320 (see FIG. 3). The cross-sectional view illustrates the channel 460 extending between the first and second spacer-side portions 462, 464 in a direction generally aligned with the lateral axis 490. The channel 460 has a third width 484 in fig. 4. In some embodiments, the size of the channel 460 may be different than the size of the first or second apertures 336, 346. In FIG. 4, the first width 480 of the first aperture 336 is substantially less than the third width 484 of the channel 460. Similarly, the second width 482 of the second aperture 346 is less than the third width 484 of the channel 460. In one embodiment, the horizontal cross-sectional surface area associated with the channel 460 is less than the horizontal cross-sectional surface area of the first or second apertures 336, 346. In other embodiments, the width of the aperture may be substantially similar to the width of the channel 460. In other embodiments, the third width 484 may be less than the first width 480 or the second width 482. In some embodiments, the relative dimensions of the channel 460, the first aperture 336, and the second aperture 346 may facilitate the flow of air through the device 140, as will be described below.

In some embodiments, the "stacking" or positioning of the channel 460 over an aperture (e.g., first aperture 336 or second aperture 346) may allow for a continuous opening or space to be formed within the device 140 in a direction generally aligned with the vertical axis 470. In other words, in some embodiments, a continuous well ("hoistway") 450 including a volume of a portion of the passage 460 aligned directly above the first bore 336 and a volume of the first bore 336 may extend through the device 140 in a substantially vertical direction, allowing fluid communication between the passage 460 and the first bore 336. The hoistway 450 may be defined by surfaces and sidewalls of portions of different floors.

In some embodiments, the device 140 may include provisions for the airflow to move in a particular direction through the hoistway 450. In one embodiment, the hoistway 450 may lead to or include the valve opening 402. The valve opening 402 may comprise an opening or passage formed in a lower surface of the device 140. In fig. 4, the valve opening 402 is associated with a bottommost region of the hoistway 450. As described above, in some embodiments, a portion of bottom substrate layer 330 may provide an outermost or lower surface of device 140. In some embodiments, the valve opening 402 may be in fluid communication with the second aperture 346 or disposed adjacent to the second aperture 346. In addition, second aperture 346 may also include an opening or passage formed in a lower or outermost surface of device 140. In fig. 4, the second aperture 346 has a port opening 404, which port opening 404 may provide an access for the device 140.

However, as shown in fig. 4, in some embodiments, a cover portion 360 may be disposed between a portion of the bottom substrate layer 330 and the second adhesive layer 340. In some embodiments, the cover portion 360 extends completely across the space associated with the valve opening 402 such that the valve opening 402 is blocked or sealed by the cover portion 360. In other words, in some embodiments, the cover portion 360 may prevent or minimize the passage of fluid from within the hoistway 450 into the second bore 346, or from the external environment into the hoistway 450. In one embodiment, the cover portion 360 creates a seal between the valve opening 402 and the second aperture 346. Although the cover portion 360 is shown in fig. 4 as extending across the entire width of the elongated portion 221, it should be understood that the cover portion 360 may have any width or dimension. In other words, in other embodiments, the cover portion 360 may be smaller in size so long as it is sized sufficiently to completely cover the valve opening 402.

In some embodiments, a conduit providing a passage for air or fluid through device 140 may extend through active portion 210 and into tail portion 220. For reference purposes, it will be understood that the conduit includes both a "horizontal passage" and a well 450 (as discussed above). In some embodiments, the horizontal passage may be in fluid communication with the hoistway 450.

Referring to fig. 5, one embodiment of a horizontal channel 550 in the device 140 is depicted. In some embodiments, horizontal via 550 may extend from active portion 210 to tail portion 220 along a plane aligned with longitudinal axis 480. Further, in some embodiments, the horizontal via 550 may include a space or opening associated with a gap formed by the inclusion of the first adhesive layer 320 between the top substrate layer 310 and the bottom substrate layer 330 (i.e., through the exposed region 350 of the first adhesive layer 320).

As described above, in some embodiments, a force may be applied to the active portion 210 (represented by the two large arrows pointing downward in fig. 5). In some cases, air disposed within the chamber 500 associated with the active portion 210 defined by the inner sidewalls of the first adhesive layer 320 may flow or otherwise move from within the chamber 500. For example, when actuation occurs, the top substrate layer 310 may be pushed inward toward the bottom substrate layer 330. In one embodiment, this may result in a reduction in volume in the chamber 500 in some embodiments, which may push or expel air out of the chamber 500. In other words, although the chamber has a first volume in a neutral state and a second volume in an actuated state, in some embodiments, the first volume of the chamber is greater than the second volume of the chamber. In some embodiments, air may move such that it flows out of active portion 210. In one embodiment, air may be exhausted through the outlet 510. In some embodiments, the outlet 510 includes a passageway or opening connecting the cavity 500 of the active portion 210 with the channel 460 of the tail portion 220, allowing air to communicate between the active portion 210 and the tail portion 220. In various embodiments, once the air flows into the tail portion 220, the air may be directed into other regions of the conduit.

Referring now to the cross-sectional view of the tail portion 220 depicted in fig. 6, it can be seen that in some embodiments, air may travel or move from a horizontal path (see fig. 5) and into a hoistway 450 (described in detail above with respect to fig. 4). Thus, in some embodiments, air may move along a first flow path through the device 140 corresponding to a horizontal pathway (as shown in fig. 5) and continue along a second flow path corresponding to a vertically oriented hoistway 450, as shown in fig. 6. In other words, in various embodiments, air may move from the active portion and into the tail portion in a substantially continuous manner as compression of the active portion occurs.

One embodiment of a flow path for air provided by the conduit 700 in the device 140 is illustrated in the schematic cross-section of fig. 7. In fig. 7, the active portion 210 is connected to the tail portion 220. Chamber 500 extends through active portion 210 in a space or cavity present between top substrate layer 310 and bottom substrate layer 330 when device 140 is in an uncompressed or neutral state. The arrows indicating the flow path are shown in the region where the thickness of the active portion 210 is undergoing deformation and is in the process of transitioning from a neutral (uncompressed) state to an actuated (compressed) state. In other words, when device 140 is actuated or a force is exerted on active portion 210, top substrate layer 310 may be pushed downward and reduce the volume of chamber 500. In some embodiments, as previously described, air may be pushed or exhausted outward toward tail portion 220 via outlet 510. In some embodiments, the airflow continues along a horizontal flow path and may reach an area of the device 140 associated with the hoistway 450. While in various embodiments, some air may continue forward in a direction generally aligned with the longitudinal axis 480 and into the portion of the passage 460 disposed closer to the connector portion (see fig. 2), it can be seen that in some embodiments, some, most, or substantially all of the air moving from the active portion 210 may be directed into the vertical flow path associated with the hoistway 450.

In some embodiments, as air moves from the channel 460 in a generally downward direction and enters the first aperture 336, some of the air may contact the inward facing surface 710 of the cover portion 360. As the air flow increases, the pressure exerted by the air against the inward facing surface 710 of the cover portion 360 increases. In some embodiments, if a sufficient amount of air pressure is present, the cover portion 360 may undergo elastic deformation, as will be discussed further below with reference to fig. 9-12. In other words, in some embodiments, the elastic membrane including the cover portion 360 may deform in response to increased air pressure in the hoistway 450.

Furthermore, as described above with respect to fig. 1, in various embodiments, device 140 may be used within a sole structure of an article of footwear. Referring now to fig. 8, sole structure 104 is depicted. In various embodiments, sole structure 104 may include provisions for receiving, attaching, or otherwise containing device 140. In fig. 8, sole structure 104 is shown with a cavity 810 formed within heel region 145. In certain embodiments, the cavity 810 may be configured to receive the device 140. In one embodiment, the cavity 810 may be sized and dimensioned to allow the device 140 to be inserted into the cavity 810 and/or fit snugly into the cavity 810. In one embodiment, cavity 810 may include a height sufficient to completely receive or enclose the sides or thickness of device 140 such that the outermost top surface of device 140 is flush with the rest of sole structure 104. In some embodiments, substantially the entire device 140 may be received within sole structure 104. However, in other embodiments, only a portion of device 140 may be inserted within sole structure 104.

In various embodiments, the cavity 810 may include provisions for accommodating dimensional changes in and/or deformations associated with the cover portion (as will be described further below). In the enlarged side view of fig. 8, an embodiment of the chamber 810 is shown in more detail. It can be seen that in some embodiments, the cavity 810 may include a "cathedral floor" or recess 820. In some embodiments, the recess 820 may be positioned to correspond with a valve opening of the device 140 (see fig. 4) when the device 140 is installed in the cavity 810 of the sole structure 104. In one embodiment, the recess 820 is sized and dimensioned to allow the cover portion to freely expand when the device 140 is subjected to maximum air pressure in the hoistway, as will be discussed with reference to fig. 9-12.

Referring now to fig. 9, a schematic view of a longitudinal cross-section taken along the longitudinal axis 180 in fig. 8 of the device 140 in a neutral state is depicted, and in fig. 10, a schematic view of a longitudinal cross-section taken along the longitudinal axis 180 in fig. 8 of the device 140 in an actuated state is depicted. In fig. 9, it can be seen that in the neutral state, the gas pressure is generally evenly distributed throughout different regions of the conduit 700. In some implementations, in a neutral state, the air pressure associated with the hoistway 450 is minimal. The cover portion 360 disposed adjacent to the valve opening 402 and covering the valve opening 402 is in a flat configuration. The inward facing surface 710 of the cover portion 360 may be understood to have a first surface area in the neutral state.

When a force is applied to the device 140, the air pressure may redistribute in some cases. In some embodiments, the air pressure associated with the hoistway 450 may be increased. As the airflow applies more and more force against the inward facing surface 710, it can be seen that in some embodiments, the cover portion 360 may deform. In one embodiment, as shown in fig. 10, cover portion 360 may be stretched and extended outwardly. Initially, the cover portion 360 may protrude downward into a space associated with the second hole 346. As the air pressure increases, the degree of deformation of the cover portion 360 may also increase. In some embodiments, cover portion 360 may expand or bulge downward beyond the perimeter of device 140 such that inward facing surface 710 forms a generally concave surface. Further, the inwardly facing surface 710 of the cover portion 360 may be understood to have a second surface area in the actuated state that is substantially larger than the first surface area of the cover portion 360 in the neutral state.

Accordingly, in various embodiments, when device 140 is installed in sole structure 104, as shown in fig. 9 and 10, cover portion 360 may deform, expand, and/or extend into the space associated with recess 820 of cavity 810. In some embodiments, recess 820 may be configured to receive and/or accommodate varying shapes and sizes of cover portion 360. In other words, during use of the device 140, air may be directed or moved through the device 140 along the flow paths described herein when pressure is applied on the device 140 by the foot, for example.

For the sake of clarity, another view of the deformation process of the covering part 360 is depicted in the transverse cross section of fig. 11 and 12. In fig. 11, a longitudinal cross-section taken along the lateral axis 490 of fig. 8 of the device 140 in a neutral state is depicted, and a schematic view of the longitudinal cross-section taken along the lateral axis 490 of fig. 8 of the device 140 in an actuated state is depicted in fig. 12. As previously mentioned, in the neutral state, the gas pressure is generally evenly distributed throughout different regions of the conduit. In some implementations, in a neutral state, the air pressure associated with the hoistway 450 is minimal. The cover portion 360 disposed adjacent to the valve opening 402 and covering the valve opening 402 is in a flat configuration. When a normal force is applied to the active portion of the device 140, the air pressure may redistribute in some embodiments. In some embodiments, the air pressure associated with the hoistway 450 may be increased.

As the airflow applies more and more force against the inward facing surface 710, it can be seen that in some embodiments, the cover portion 360 may deform. In one embodiment, as shown in fig. 12, cover portion 360 may be stretched and extended outwardly. Initially, the cover portion 360 may protrude downward into a space associated with the second hole 346. As the air pressure applied against the inward facing surface 710 of the cover portion 360 increases, the degree of deformation of the cover portion 360 may also increase. In some embodiments, cover portion 360 may expand or bulge downward beyond the perimeter of device 140 such that inward facing surface 710 forms a generally concave surface.

Further, as described above, in various embodiments, when device 140 is installed in sole structure 104, as shown in fig. 11 and 12, cover portion 360 may deform, expand, and/or extend into the space associated with recess 820 of cavity 810.

Thus, in some embodiments, it is understood that the cover portion 360 may include an inflatable membrane forming a sealing area over the valve opening 402 of the hoistway 450. The inclusion of the elastic material may provide an adjustable mechanism for the device 140 to receive air that may be displaced when a force is applied to the device 140. In some embodiments, the use of the cover portion 360 can form a substantially water-resistant or waterproof seal and protect the interior of the device 140 from external particles or other materials that may undesirably affect the use of the device 140. Furthermore, the elastic membrane extending across the opening formed in the lower surface of device 140 may help mitigate "flattening" of the sensor by providing a restoring force in device 140. In other words, because cover portion 360 is made of an elastic material, once the force exerted on the active portion is released and the chamber space is restored, in some embodiments, cover portion 360 can revert to a contracted or flattened configuration, pushing air back into the flow path in the opposite direction, and facilitating expansion of the chamber to its original shape and/or size. This process is schematically depicted in the longitudinal cross-section of fig. 13 and 14.

In fig. 13 and 14, another embodiment of a flow path for air provided by a conduit in the device 140 when the force is removed is illustrated. In fig. 13, arrows indicating the flow path during the actuated state are shown. When active portion 210 undergoes deformation, top substrate layer 310 is pushed downward, reducing the volume of chamber 500. As previously described, in some embodiments, some, most, or substantially all of the air moving from the active portion 210 may be directed along the horizontal pathway 550 to the vertical flow path associated with the hoistway 450. However, when the force is removed, active portion 210 and chamber 500 may return to their configurations in an uncompressed or neutral state.

In some embodiments, when the force is removed, air may move in a generally upward direction from the first bore 336 out of the hoistway 450 into the channel 460. Thus, in some embodiments, at least some of the air previously pressed against the cover portion 360 may move away from the cover portion 360 and toward the chamber 500. In some embodiments, as air continues to move away from the hoistway 450 and disperse into the passage 460 and through the passage 460, the chamber 500 may expand as the air pressure in the chamber 500 increases. In some embodiments, covering portion 360 may resiliently return to a flat configuration. In other words, in some embodiments, the elastic membrane including the cover portion 360 may contract back to its pre-deformed configuration in response to a decrease in air pressure in the hoistway 450.

In various embodiments, placing the cover portion 360 between the bottom substrate layer 330 and the second adhesive layer 340 allows the cover portion 360 to be secured by an adhesive bond formed between the two layers. However, in other embodiments, the cover portion may be disposed along other regions or layers of the device 140. For example, in some embodiments, cover portion 360 may be placed adjacent port opening 404 on the outermost surface of second adhesive layer 340, referred to herein as outer adhesive surface 1510. Referring to fig. 15 and 16, an alternative embodiment is depicted in which the cover portion 360 is attached to the outer adhesive surface 1510. In fig. 15 and 16, the hoistway 1550 is depicted as extending in a generally vertical direction from the passage 460 into the first bore 336, through the valve opening 402, and into the second bore 346. In other words, in some embodiments, "stacking" or positioning of the passage 460 above the aperture (e.g., the first aperture 336 or the second aperture 346) may allow for a continuous opening or space to be formed within the device 140 in a direction generally aligned with the vertical axis 470 that is larger than the hoistway 450 previously described. In other words, in some embodiments, the well 1550 includes a volume of a portion of the passage directly aligned above the first aperture 336, a volume of the first aperture 336, and a volume of the second aperture 346, the well 1550 may extend through the device 140 in a substantially vertical direction, allowing fluid communication between the passage 460, the first aperture 336, and the second aperture 346. The well 1550 may be defined by surfaces and sidewalls of portions of different layers.

Additionally, in some embodiments, device 140 may include additional provisions for securing cover portion 360 to device 140. In one embodiment, as shown in fig. 15 and 16, the cover portion 360 may be disposed between a portion of the second adhesive layer 340 and the securing layer 1520. In other embodiments, the device 140 may not include the securing layer 1520 and the cover portion 360 may be secured to the second adhesive layer 340 in other ways. For example, the cover portion 360 may include adhesive along one side of the cover portion that bonds the cover portion 360 to the outer adhesive surface 1510 of the second adhesive layer 340.

Additionally, in some embodiments, the cover portion 360 extends completely across the space associated with the port opening 404 such that the port opening 404 is blocked or sealed by the cover portion 360. In other words, in some embodiments, the cover portion 360 may prevent or minimize the passage of fluid from within the well 1550 to outside of the device 140, or from the external environment into the well 1550. In one embodiment, cover portion 360 creates a seal between port opening 404 and the external environment. Although the cover portion 360 is shown in fig. 15 and 16 as extending across the entire width of the elongated portion 221, it should be understood that the cover portion 360 may have any width or dimension. In other words, in other embodiments, the size of the cover portion 360 may be smaller as long as it is sized enough to completely cover the port opening 404.

In various embodiments, the horizontal passageways described herein can provide a first flow path through the device 140, and the hoistway as described with respect to fig. 15 and 16 can provide a second flow path through the device 140. Thus, in some embodiments, the air pressure may exert a force on the cover portion 360 when the cover portion 360 is positioned against the external adhesive surface 1510. In fig. 15 and 16, the expansion or deformation process of the covering part 360 as described before is shown. However, in fig. 15, it can be seen that cover portion 360 expands from the flat configuration when aligned with port opening 404 rather than valve opening 402.

Additionally, in various embodiments, the apparatus 140 may include provisions for securing the cover portion 360 to the second adhesive layer 340. For example, in some cases, while the adhesive may be applied on the cover portion 360, the bonding may be improved by a securing layer wrapped around the cover portion. In some embodiments, the securing layer may increase the stability of the covering portion when shear forces within the shoe are exerted on the covering portion.

As an example, fig. 17 and 18 depict the attachment of a securing layer 1520 around the elongated portion 221. In fig. 17, a folded sheet of material including a securing layer 1520 is shown adjacent to the device 140. In fig. 18, a securing layer 1520 has been disposed around the elongated portion 221 and bonded to the outermost surface of the elongated portion 221. As can be seen, the fixed layer 1520 also includes a third aperture 1710. When the securing layer 1520 is positioned on the device 140 and substantially surrounds the elongated portion 221, the third aperture 1710 may be aligned with the port opening and the covering portion 360. In other words, the third aperture 1710 may be sized and dimensioned to surround and bound the port opening such that a region of the cover portion 360 extending across the port opening remains free and exposed. Thus, after the securing layer 1520 has been attached to the device 140, the covering portion 360 may continue to expand and/or deform as described herein.

In some embodiments, the securing layer 1520 may comprise various materials. In one embodiment, securing layer 1520 comprises a polyimide tape having a hole (i.e., third hole 1710) wrapped around device 140 and spanning a portion of cover portion 360. In other embodiments, the securing layer 1520 may comprise any type of tape or film known in the art for use in electronic devices or other instruments.

Thus, in different embodiments, the flow paths described herein may be used to move air through the sensor device in different ways. For illustrative purposes, fig. 19 provides a flow chart describing one method of moving air through a sensor device (labeled 1910) including a top substrate layer, a first adhesive layer, and a bottom substrate layer, and an active portion and a tail portion. In one embodiment, the method includes a first step 1920 that includes moving air from the active portion into a horizontal passage formed in the sensor device when the active portion is compressed. In some embodiments, second step 1930 comprises moving air from the active portion to a vertical channel disposed in the tail portion in the bottom substrate layer. Further, in some embodiments, the third step 1940 may comprise inflating an elastic membrane exposed to the increased air pressure.

In other embodiments, the method may further include returning air to a chamber formed in the active portion when the active portion is no longer compressed. Additionally, in some embodiments, the first step 1920 of moving air from the active portion into the horizontal passage may further include moving air from a chamber formed between the top substrate layer and the bottom substrate layer within the active portion into a channel formed in the tail portion. In one embodiment, the method may further comprise shrinking the elastic membrane when the air returns to the chamber in the active portion.
