Technical Field

One or more embodiments of the present invention generally relate to cleaning devices. More particularly, certain embodiments of the present invention relate to cleaning devices that include multiple tools in one assembly.

Background

The following background information may present examples of certain aspects of the prior art (e.g., without limitation, methods, facts, or common sense), and while it is intended to help further educate the reader about other aspects of the prior art, should not be construed as limiting the present invention, or any embodiments thereof, to anything described or suggested herein or inferred therefrom. In general, cleaning the air ducts and/or drains is a labor intensive task because of the need to twist and force the rigid hoses to become flexible and/or turn around the ducts and/or tubes. Duct cleaning technicians often use agitation tools to clean hvac systems. These tools may include a burst ball that uses high pressure air to propel itself down a pipe by back-injecting air to the technician. The burst ball is generally easy to use, but may not sufficiently agitate the duct walls to remove dirt and debris. Other blending tools, such as a scrubbing cord and brush, may be attached to the rigid hose and pushed down the pipe. These types of tools may be more effective in cleaning; however, when using such tools, it is often difficult to reach the other end of the ductwork due to, among other things, the turning of the duct and the length of the ductwork. Pipe cleaning is often a two-person task because the process of operating the hose can be challenging and winding problems can occur where the hose and/or air line become stuck or diverted in the air pipe. Technicians can often use multiple channels and different tools to effectively clean the air chute. In addition to cleaning tools, technicians can use cameras to inspect hvac and plumbing at the end of the pipeline while cleaning. It is expected that the technician may encounter problems similar to those described above, which may make it difficult for the camera to reach the desired location.

In view of the above, it is clear that these conventional techniques are not perfect and leave room for a more optimal approach.

Detailed Description

The invention can be best understood by reference to the detailed drawings and description that follow.

Embodiments of the invention are discussed below with reference to the figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. For example, it should be understood that those skilled in the art, in light of the teachings of the present invention, will recognize a variety of alternative and suitable ways to implement the functionality of any given detail described herein, as required by a particular application, and is not limited to the particular implementation choices in the embodiments described and illustrated below. In other words, the present invention is subject to numerous modifications and variations, not listed, but within the scope of the present invention. Furthermore, singular words shall be equivalent to plural, and vice versa; a positive word is equivalent to a negative word and vice versa. Embodiments and alternatives do not necessarily mean that they are mutually exclusive, where appropriate.

It is to be further understood that this invention is not limited to the particular methodology, mixtures, materials, manufacturing techniques, uses, and applications described herein, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that, as used herein and in the appended claims, the singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. Thus, for example, reference to "an element" is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to "a step" or "a means" is a reference to one or more steps or means and may include sub-steps and dependent means. All conjunctions used are to be understood in the sense of being as inclusive as possible. Thus, the term "or" should be understood to mean a definition of "or" in a logical sense, rather than a definition of "exclusive or" logically, unless the context clearly requires otherwise. Structures described herein are also to be understood as referring to functional equivalents of such structures. The language used to express "approximations" is to be understood as "approximate" unless the context requires otherwise.

All words expressing "approximate" as used in this disclosure and the claims are to be interpreted as "approximate" and not "perfect," and thus can be used as meaningful modifiers of any other word, specified parameter, quantity, quality, or concept. Words expressing "approximations" include, but are not limited to, the terms "substantial," "proximate," "about," "generally," "substantially," "approximately," and the like.

As will be explained in more detail below, the words "approximate" are well defined in the law as early as 1939 and are not uncertain in the claims even if no definition or limitation is made in the description.

For example, in the 52USPQ 297,297 (pat. off.bd.app. 1941), referred to in the malori case, the court call "examiner considers most claims to be inaccurate because it is clear that the sheet-like film is not completely eliminated. The claims indicate that the film is "substantially" eliminated and that, for the intended purpose, it is believed that negligible minute portions of the film may remain. Accordingly, it is believed that the claims will be sufficiently accurate. "

It is noted that the claims need only "reasonably apprise those skilled in the art" scope to meet the explicit requirements. See energy absorption systems company, complaint road safety services company, docket number civ.app.96-1264, court opinion 10 (federal publication 1997, 7/3/10, unpublished). The hybrid technology company referred to monoclonal antibodies, docket No. 802f.2d1367, 1385, 231USPQ 81, 94 (federal publication 1986), supra, 480u.s.947 (1987). Furthermore, the use of modifiers such as "generally" and "substantially" in the claims does not inherently alter the claims. See Seattle Box Inc. claiming Industrial boxing and packaging Inc., docket number 731F.2d 818, 828-29, 221USPQ 568, 575-76 (Federal publication 1984).

Moreover, the ordinary and customary meaning of a term such as "substantially" includes "reasonably close, near, nearly, about," meaning an approximation. See refery supra, publication No. 2009-06013, 94USPQ2D 1072,1077,2010WL 889747 (2010 committee on patent supra and dispute). The term "substantially" may mean either an approximation language or a degree language, depending on its usage. Such as dilin precision instruments filed the wecker distribution systems, docket 347 f.3dw1314, 1323 (federal publication 2003) (recognizing the word "substantially" as an approximation word or "two general meanings" representing degrees). In this context, when referring to the limitation of "substantially in the middle", the word "approximately" is used in the description instead of the word "substantially" (fact 4). Thus, "substantially in the middle" is generally equivalent to being near or near the midpoint between the forward-most point of the upper or outsole and the rearward-most point of the upper or outsole.

Similarly, the word "substantially" is used in the case law to have a double ordinary meaning as a word of approximation or a word of degree of representation. See dana for U.S. axle manufacturing, docket number civ.app.04-1116,2004, upper court of america, lex 18265, 13-14 (federal gazette 2004, 8/27, unpublished). The term "substantially" is commonly used by the drafter of the claims to indicate an approximation. See cortis, maydongli, No. 339f.3d 1352, 1360 (federal publication 2003). The term "substantially" is used in this context to denote an approximation, therefore, the wall must be of substantially or approximately uniform thickness ", see also delrin precision instruments, inc. complaint vickers distribution, No. 347E3D 1314,1322 (federal publication 2003); the empokon natural gas systems company filed the boyle compressor, docket No. 279f.3d 1022, 1031 (federal publication 2002). We have found that the term "substantially" is used in the claims of patent litigation in such a way that "substantially uniform wall thickness" means approximately uniform wall thickness.

It should also be noted that the foregoing approximate terms clearly limit the scope of the claims, for example, the adverb "generally" in "generally parallel" does not extend the meaning of parallel. Thus, the foregoing discussed approximating language (e.g., the phrase "generally parallel") is intended to solve some of the departure from perfection (e.g., not completely parallel), and is a descriptive term commonly used in the patent claims to avoid using strict numerical boundaries for the specified parameters. In accordance with the colloquial language of the words of the approximation set forth above in the claims, anything in the written description herein or in the figures thereof is clear and inconsistent and should not be relied upon to raise any limitation by existing written descriptions, numbers or historical prosecution. The claims of the present invention relate to approximating words in the above-mentioned conception. That is, in such cases, it is not permissible to rely on textual description and historical prosecution to negate the ordinary and customary meaning of the word itself. See, for example, Warne, Inc., of liquid mechanics, U.S. Pat. No. 355F.3d 1361, 69USPQ2d 1595, 1600-01 (Federal publication 2004). The colloquial language of phrase 2 means that a "substantial helical flow" is required. The term "substantially" is a meaningful modifier, meaning "approximately" rather than "perfectly". In the case of Kedi's complaint of Meidunli, title 339F.3D 1352,1361 (Federal publication 2003), the regional court imposes a precise numerical limit on the term "substantially uniform thickness". We note that the proper interpretation of this term is "substantially or near uniform thickness" unless the party has historically stated "a terse disclaimer" to override this simple language interpretation. In the case of Loxwood wall protection, Ankou wall systems, Inc., 340F.3d 1298, 1311 (Federal publication 2003) "on page 1311, supra. Similarly, the colloquial language of claim 1 means that neither full helical flow nor flow that returns exactly to the centre after one revolution is required (a restriction that arises only when the logical result of full helical flow is required).

The reader should understand that the case law generally recognizes the dual general meaning of these terms as approximations, as set forth above, as terms of an approximation or an order of magnitude. See, for example, delin precision instruments ltd, filed the wekko distribution systems, docket No. 347R3d 1314, 68USPQ2d 1716, 1721 (federal publication 2003), the above refute, 124s.ct.1426 (2004), the court of law for interpreting the meaning of the word "substantially" in the patent claims. Likewise, in the phrase 1031(279), this phrase means "approximately constant", whereas the phrase "largely lower than" means "order of magnitude language", i.e., "insubstantial". Further, see empokon natural gas systems, inc, filed under boell compressor, docket No. 279f.3d 1022, 1031 (federal publication 2002) (the terms "substantially unchanged" and "substantially below" are explained); constellation pool Care company complaint Hofenge industries, Inc., docket No. 206F.3d 1408 (Federal 2000) (the term "substantially in" is explained); york contactor company resorted to century tractor farm and home center case, case No. 99f.3d 1568 (federal publication 1996) (the term "substantially its entire height" is explained); texas instruments Inc. resorts to the Bertree semiconductor corporation, docket No. 90F.3d1558 (Federal publication 1996) (the term "substantially on a common plane" is explained). In conducting the analysis, the court instructions begin with the ordinary meaning of the words used in the claims to those of ordinary skill in the art. See Prima Tek, 318f.3d, page 1148. From the dictionary and our case, the word "substantially" has many common meanings. As with the regional court, "substantially" may mean "significantly" or "equivalently". The term "substantially" may also mean "largely" or "essentially". Webster's new version of the twentieth dictionary, page 1817 (1983).

As previously mentioned, words representing approximate values may also be used to establish phrases of approximate extent or limitation, where the endpoints are inclusive and approximate, not perfect; for example, see AK iron and Steel company complaint Soraoke, U.S. Pat. No. 344F.3D 1234,68USPQ2D1280,1285 (Federal publication 2003), which is recognized by the law that the general meaning of the term "up to about 10%" includes the end of "about 10%". As pointed out by AK steel company, when the object of the preposition "up" is not a number, the most natural meaning is to exclude the object (e.g., brush the wall to the door). On the other hand, when the subject is a numerical limit, as indicated by sorak, the usual meaning is to include the numerical upper limit (e.g., up to 7 passengers may have up to 10 seats). Since we have a numerical limitation here, i.e. "about 10%", the usual meaning encompasses this end point.

In the present description and claims, in summary, the above approximation words are used for the purpose of avoiding strict value boundaries of the specified parameters after modification, as determined in the case of the division by the gill company of the miklong separator, under the designation 66E3D 1211,1217 1211,1217,36USPQ2D 1225,1229 (federal gazette 1995), which states: the term 'substantially' is used to reasonably describe the subject matter so that those skilled in the art will understand its scope and distinguish the claimed subject matter from the prior art, where it is uncertain. See also vif for claiming a case by clainn camera, nos. 311R3d1116, 65USPQ2d 1051, 1054 (federal gazette 2002). Expressions such as "substantially" are used in the patent document, adaptable to protect minor variations of the invention when warranted by the nature of the invention. Such usage is well within the ambit of the "specifically identified and distinctly claimed" invention, in accordance with article 112 of chapter 35 of the united states code of law, and may indeed be necessary to provide the inventors with the benefit of their invention. In the case of Andrew complaint Boolean electric company, cases 847F.2d 819,821-22,6USPQ2d 2010,2013 (Federal publication 1988), it is explained that the use of "substantially equal" and "approximately close" can be used to describe the invention, with a precision suitable for the technology, without interfering with the prior art. The court also judges that "similar to the word" about, "the word" substantially "is a descriptive term commonly used in patent rights to avoid strict numerical boundaries for specified parameters" in the case of environmental chemistry filed by the laboratory in the department of electronics, under the case of 264f.3d 13581367, 60USPQ2d1173, 1179 (federal publication 2001), see the case of environmental chemistry filed by the laboratory in the department of electronics, 264f.3d 1358, 60USPQ2d1173, 1179. In this case, the term "substantially" is used to modify the term "substantially" without making the phrase ambiguous so as to make the scope of the claims uncertain.

Similarly, other courts note that, like the word "about," the word "substantially" is also a descriptive term commonly used in the patent claims for the purpose of "avoiding strict numerical limitations on specified parameters. See, for example, paler, miklong separator, case No. 66f.3d 1211,1217,36USPQ2d 1225,1229 (federal gazette 1988); see Andrew, Inc. claiming Boolean electric case, U.S. Pat. Nos. 847F.2d 819,821-22,6USPQ2d 2010,2013 (Federal publication 1988) (noting that terms such as "proximate to each other," "proximate," "substantially equal," and "nearly similar" are commonly used in patent applications and this usage is used when reasonably describing the claimed subject matter as a person skilled in the art of the present invention and to distinguish the claimed subject matter from prior art which has passed patent examination and received court support). In this case, "substantially" avoids strict 100% non-uniformity boundaries.

In fact, judgments about the words representing approximations described above have appeared as early as 1939, see malori, 52UPQ 297,297 (patent prosecution and dispute commission 1941), in which, for example, the court of law deems that "the claims indicate that the film is 'substantially' deleted and that for the intended purpose, a small portion of the film that can remain is considered negligible. Accordingly, it is believed that the claims will be sufficiently accurate. "likewise, in the Hacqenson-one, case numbers 104E2d 829, 42USPQ 90, 93 (Calif. Consumer protection act, 1939), court letters" realizing "substantial distance" is a relative, somewhat uncertain term or phrase, but in patents, terms and phrases of this nature are not uncommon, as their meaning can be reasonably clearly determined according to the technology involved. "

Accordingly, for at least the foregoing reasons, applicants propose that any examiner should not consider any words used in the patent claims to represent approximations to be uncertain.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein can be used in the practice or testing of the present invention. Structures described herein are also to be understood as referring to functional equivalents of such structures. The invention will be described in detail below with reference to embodiments of the invention shown in the drawings.

In the preamble of the claims, references to "device", "apparatus", "system", etc., are to be interpreted broadly as "any structure which meets the terms of the claims" except where expressly denied, excluded or acknowledged/implied as prior art to the specification or as failing to meet the object/aspect/goal of the invention. Furthermore, if this specification discloses objects, aspects, functions, objectives, results or advantages of the invention that certain prior art structures and/or method steps may likewise be performed in a very different manner, then the disclosure of the present invention is intended to, and should also implicitly include and encompass, that the corresponding alternative embodiments are the same as the explicitly disclosed alternative embodiments, but that it excludes such prior art structures/steps and is therefore to be considered as sufficiently disclosing to support a corresponding negative limitation in the claims that claim such alternative embodiments, in which different prior art structures/steps are excluded.

Other variations and modifications will be apparent to persons skilled in the art upon reading the present disclosure. Such variations and modifications may involve equivalent and other functions which are already known in the art, and which may be used instead of or in addition to functions already described herein.

Although claims have been formulated in this application to particular combinations of features, it should be understood that the scope of the disclosure of the present invention also includes any novel feature or any novel combination of features disclosed herein (either explicitly or implicitly or any generalisation thereof), whether or not it relates to the same invention as presently claimed in any claim and whether or not it mitigates any or all of the same technical problems as does the present invention.

Functionality described in the context of separate embodiments may also be provided in combination in a single embodiment. Conversely, various functions described in the context of a single embodiment may also be provided separately or in any suitable subcombination for brevity. The applicants hereby give notice that new claims may be formulated to such features and/or combinations of such features during the prosecution of the present application or of any further application derived therefrom.

References to "one embodiment," "an example embodiment," "various embodiments," "some embodiments," "an embodiment of the invention," etc., may indicate that the embodiment of the invention so described may include a particular function, structure, or characteristic, but every possible embodiment of the invention may not necessarily include the particular function, structure, or characteristic. Furthermore, repeated use of the phrases "in one embodiment" or "in an exemplary embodiment," "an embodiment," and "certain embodiments" do not necessarily refer to the same embodiment, although they may. Furthermore, phrases similar to "embodiments" used in connection with the present invention in no way imply that all embodiments described herein must include a particular feature, structure, or characteristic, but rather should be understood to mean that "at least some embodiments of the invention" include the particular feature, structure, or characteristic.

As used herein, a "user" or any similar term may refer to a human or non-human user thereof. Further, unless expressly stated otherwise, "user" or any similar term as used herein means a user at any stage of the use process, including but not limited to direct users, intermediate users, indirect users, and end users. The meaning of "user" or any similar term used herein should not be inferred or induced in other ways by the description, embodiments, examples that may be provided in this patent (or may not be provided) or by any mode of reference to the prior art.

As used herein, "end user" or any similar term, refers generally to a later user rather than an earlier user. It is therefore contemplated that there may be a number of different types of "end users" near the end stage of the usage process. Where applicable, particularly with respect to the distribution channels of embodiments of the present invention, which include retail products/services being consumed (as opposed to sellers/distributors or original equipment manufacturers), "end-user" examples may include, but are not limited to, "consumers," "buyers," "customers," "buyers," "shoppers," "users," "viewers," or personal or non-human things that in any way benefit, directly or indirectly, from use or interaction with certain aspects of the present invention.

In some cases, some embodiments of the invention may provide benefits for multiple stages or types of use during the above-described use. Where multiple embodiments are described for various stages of a usage process, references to "end user" or any similar terms used therein are generally intended to not include the user farthest from the end user in the preceding usage process in embodiments of the invention.

Where applicable, particularly with respect to retail distribution channels of embodiments of the present invention, intermediary users may include, but are not limited to, any personal or non-human item that directly or indirectly benefits from use or interaction with an aspect of the present invention in any manner, including sales, original equipment manufacturing, marketing, merchandising, distribution, serving, and the like.

References to "human", "person", "human", "party", "animal", "biological", or any similar term used herein, even though the context or particular embodiment implies a living user, manufacturer, or participant, should be understood that such features are by way of example only and not limitation, in which case it is contemplated that any such use, manufacture, or participation associated with manufacturing, using, and/or participating in embodiments of the invention in any way may be replaced by such similar operations as may be performed by appropriately configured non-living entities, to include, but are not limited to, automated machines, robots, humanoid robots, computing systems, information handling systems, artificial intelligence systems, and the like. It is further contemplated that one skilled in the art will readily recognize the fact that such live manufacturers, users, and/or participants having embodiments of the present invention may be substituted, in whole or in part, for such non-live manufacturers, users, and/or participants having embodiments of the present invention. Also, when such an actual situation is recognized by one of ordinary skill in the art, such in vivo manufacturers, users, and/or participants having embodiments of the present invention may be replaced, in whole or in part, by such non-in vivo manufacturers. It will be apparent from the teachings of the present invention how to adapt the described embodiments to such non-living manufacturers, users and/or participants having embodiments of the present invention. Accordingly, the invention also includes all such modifications, equivalents, and alternatives falling, at least in part, within the spirit and scope of the modifications and alternatives to such non-living entities.

Headings are provided herein for convenience and should not be viewed as limiting the disclosure in any way.

The enumerated listing of items does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise.

It should be understood that the particular component, device, and/or parameter names are used by way of example only and are not meant to limit the present invention in any way. Thus, the present invention may use different nomenclature/terminology for describing the mechanisms/elements/structures/components/devices/parameters herein, and is not limited. Each term used herein should be given its broadest interpretation according to the context in which it is used.

Terminology. The following paragraphs provide definitions and/or context for terms used in the present invention (including the appended claims):

"comprises". This term is open ended. As used in the appended claims, the term does not exclude additional structures or steps. Consider a statement that: "storage controller containing system cache … …," this statement does not prevent the storage controller from containing additional components (e.g., memory channel units, switches).

"configured to". Various units, circuits, or other components may be described or claimed as being "configured to" perform a task or tasks. In such cases, "configured to" or "operable to" denotes the structure by the mechanism/unit/circuit/component including the structure (e.g., circuit and/or mechanism) that performs the task during operation. Thus, the mechanism/unit/circuit/component may be configured (or operable) to perform a task even if the specified mechanism/unit/circuit/component is not currently operating (e.g., not turned on). The mechanisms/units/circuits/components used with the "configured to" or "operable to" language include hardware, e.g., executable mechanisms, structures, electronics, circuits, memory-stored programs to implement the operations, and so on. It is expressly not intended that a mechanism/device/circuit/component "configured to" or "operable to" perform one or more tasks be incorporated by reference for that mechanism/device/circuit/component as specified in chapter 35, section 112, sixth paragraph. "configured to" may also include adapting a manufacturing process to manufacture a device or component suitable for performing or carrying out one or more tasks.

"based on". As used herein, the term is used to describe one or more factors that affect an assay. This term does not exclude other factors that may influence the decision. That is, an assay may be based solely on these factors, or at least in part on these factors. Consider the phrase "determine A on a B basis". Although B may be a factor that affects the determination of a, this phrase does not exclude that a determination is also based on C. In other cases, a may be determined based on B alone.

The terms "a", "an", and "the" mean "one or more", unless expressly specified otherwise.

Unless otherwise indicated, all numbers expressing conditions, concentrations, dimensions, and so forth, used in the specification and claims are to be understood as being modified in all instances by the term "about". Accordingly, unless otherwise indicated, the numerical parameters set forth in the following specification and attached claims are approximations and may depend upon the specific analytical technique.

The term "comprising" is synonymous with "including," "comprising," or "characterized by," is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. "comprising" is a term of art used in claim language that means that the named claim element is essential, but that other claim elements may be added and still form a structure within the scope of the claims.

As used herein, the term "comprising" does not include any elements, steps or ingredients not specified in the claims. If the word "comprising" (or variations thereof) "is used in a clause of the claims, rather than following the preamble, then it is limited to the elements specified in the clause; other elements are not excluded throughout the claims. As used herein, the phrases "consisting essentially of" and "comprising" limit the scope of the claims to the specified elements or method steps, plus those elements or method steps that do not materially affect the basic and novel characteristics of the claimed subject matter (see norlian prosecution ltd, docket No. 363R3d 1321, 1331-32, 70USPQ2d 1508, federal gazette 2004). Furthermore, to any claim of the present invention, the claimed embodiments thereof "substantially comprise" or "include" a certain set of elements of any embodiment described herein. It should be clearly understood by those skilled in the art that the present invention also includes all possible individual variations of any of the described embodiments (i.e., consisting essentially of a subset of functions or a functional combination thereof), such that each of these individual variations consists essentially of any functional subset and/or functional combination of any set of elements of any of the described embodiments, excluding any other non-listed ones. That is, it is contemplated that it will be apparent to those skilled in the art how to create alternative embodiments of the present invention that consist essentially of a particular combination of functions of the elements of any described embodiment, but which do not include any other embodiments not set forth herein, and that the present invention thus encompasses all such exclusive embodiments as if they were all described herein.

With respect to the terms "comprising," "including," and "substantially comprising," if one of these terms is used herein, the subject matter of the present disclosure and claims can include the use of any of the other two terms. Thus, in some embodiments that are not otherwise explicitly described, any instance of "comprising" may be replaced with "including" or "consisting essentially of. And thus, for purposes of claim support and construction of the "comprising" format claims, these alternative operations create another alternative embodiment "substantially" that merely refers to elements described in the original "comprising" embodiment, excluding all other elements.

Unless explicitly stated otherwise, at least the devices or system modules that are in general communication with each other need not be in continuous communication with each other. Further, devices or system modules that are at least generally in communication with each other may communicate directly or indirectly through one or more intermediaries.

A description of an embodiment with multiple components in communication with each other does not imply that all such components are required. On the contrary, various optional components are described to illustrate the various possible embodiments of the present invention.

As known to those skilled in the art, when designing an optimal fabrication for a commercial implementation, many careful considerations and compromises must generally be made with respect to the system, particularly with respect to the embodiments of the invention. Commercial implementations consistent with the spirit and teachings of the invention may be configured as desired for particular applications, and thus, any aspect, feature, function, result, component, method, or step of the teachings related to any described embodiment of the invention may be suitably omitted, included, adapted, mixed and matched, or improved and/or optimized by those skilled in the art using their average and known techniques, to meet the desires of the particular application.

In the following description and claims, the terms "coupled" and "connected," along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, "connected" may be used to indicate that two or more elements are in direct physical or electrical contact with each other. "coupled" may mean that two or more elements are in direct physical or electrical contact. However, "coupled" may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.

It should be understood that any precise measurement/dimension or particular construction material shown herein is provided merely as an example of a suitable configuration and is not intended to be limiting in any way. Those skilled in the art will readily recognize numerous suitable alternative implementation details as required by the particular application in light of the following teachings.

One embodiment of the present invention may provide a cleaning device that includes a plurality of tools in one assembly. Some embodiments may be implemented as an air hose that may expel pressurized air or water through the assembly to propel the hose assembly forward, and include one or more additional air, liquid, or electrical devices that may operate independently of or in conjunction with the propulsion assembly. Some embodiments may include couplings to create multiple plenums that can be independently controlled by a technician in many applications.

1A, 1B, and 1C illustrate an exemplary cleaning device 100 including multiple tools in one assembly, according to one embodiment of the present invention. Fig. 1A is a perspective side view of the cleaning device 100. FIG. 1B is a diagrammatic side view of the cleaning device 100, and FIG. 1C is a cross-sectional side view of the cleaning device 100 with the air wiper 105 attached. In this embodiment, the cleaning device 100 includes an inner hose 110 that passes through an outer hose 115. The drive tool connector 120 and the hose connector 125 are located at each end of the outer hose 115 to typically enable the flow of air into the inner hose 110 and the flow of air into the outer hose 115 to be independently controlled. The configuration of inner hose 110 and outer hose 115 creates two air chambers, one air chamber being the space within inner hose 110 and the second air chamber being the space between inner hose 110 and outer hose 115. The inner and outer hoses 110, 115 may be flexible hoses or may be rigid components, similar to components of a spray handle. In some embodiments, the inner and outer hoses may be made from different types of hoses or tubes. For example, without limitation, in one such embodiment, the inner hose may be stiffer than the outer hose. In other embodiments, the outer hose may be stiffer than the inner hose. A variety of suitable materials may be used to form the components of the cleaning device 100, including but not limited to plastic, metal, or rubber. Further, the components may be connected to one another using a variety of different means (such as, but not limited to, threaded connections, welding, adhesives, or compression fittings). In addition, seals, gaskets, O-rings, etc. may be used at these connections to prevent loss of air or liquid in the system, as appropriate.

In this embodiment, the drive tool connector 120 is located near the cleaning end of the cleaning device 100 and includes a porous assembly 130 that enables air from the chamber between the inner hose 110 and the outer hose 115 to be forced out the back of the drive tool connector 120 to propel the cleaning device 100, as well as any additional tools, forward through the duct or tubing. The rounded shape of the drive tool connector 120 may evenly distribute the airflow escaping through the apertures 130 around the cleaning device 100, which may help ensure that the cleaning device 100 is straight ahead and may help prevent the cleaning device 100 from becoming tangled or rotating within a duct or pipe. Alternate embodiments may include various different shapes and sizes of apertures through which the airflow may escape, such as, but not limited to, an elongated slot or a nozzle-shaped passage. In addition, the tubes in the tube structure of the present embodiment may also help prevent tangling and kinking of the inner and outer hoses 110 and 115. Once the cleaning device 100 reaches the desired location, the inner hose 110 may allow an air-driven agitation device (such as, but not limited to, the air wiper 105) to be controlled by the air within the inner hose 110. Similar to that shown in the example of FIGS. 6A and 6B, near the technician end of the cleaning device 100, an air valve opposite the cleaning end may allow the technician to control the flow of air to the drive tool connector 120 and the air wiper 105. For example, and without limitation, one air valve may be connected to the hose connector 125 at the receiver 135 to control the flow of air into the space between the inner hose 110 and the outer hose 115, and another air valve may be located at the technician end of the inner hose 110 to control the flow of air into the inner hose 110. These separate gas streams may be operated together or separately as desired. In an alternative embodiment, a single air valve may be used to control the air flow into both chambers simultaneously. Those skilled in the art will readily recognize from the teachings of the present invention that the drive tool coupler 120 and any additional tools may operate using means other than air flow, such as, but not limited to, gas flow other than air, liquid, or electricity. The tools and accessories may be controlled by remote control, solenoid valves, any electrical switch or mechanical valve control. In some embodiments, a combination of devices may be used. For example, in one such embodiment, without limitation, the flow of gas or liquid may be used to operate a drive tool coupler to propel an electrical device, such as, but not limited to, a camera or an electric brush connected to an electrical cord in an internal hose.

In a typical use of the present embodiment, the cleaning device 100 may be used to clean a duct in an hvac system. The technician may first insert the cleaning device 100 into the conduit cleaning end and then turn on the air flow to the external hose 115 and the drive tool connector 120 to push the cleaning device 100 through the conduit. As the cleaning tool 100 is moved down the duct, the air flow to the inner hose 110 may also be turned on so that the air wiper 105 can agitate debris within the duct. Alternatively, the air flow to the inner hose 110 may remain closed until the cleaning device 100 reaches a desired location within the duct, at which point the air flow to the inner hose 110 may be turned on to operate the air wiper 105. Both the air used to drive the cleaning tool and the cleaning tool itself are controlled by the technician at the end of the cleaning apparatus. In use of the device, the system will be under negative pressure, pulling debris expelled by the blending tool. It is contemplated that a variety of suitable implements may be attached to the cleaning device to be propelled through the pipe or conduit, such as, but not limited to, a brush, sponge, sprayer, camera, video camera, vacuum cleaner, light, or magnet. Further, in the present embodiment, the tools attached to the cleaning device 100 may be interchangeable to typically enable a technician to customize the cleaning technique to the requirements of the current task. One way to accomplish this is to provide the tool connector 140 with means to allow a tool to be connected to and disconnected from the cleaning end of the cleaning device 100. Such methods may include, but are not limited to, threaded connectors, compression fit connectors and drill chuck type devices, quick connectors, injection molds, castings, and set screws. In other embodiments, the tool coupler may be built into the drive tool coupler. In some applications, the drive tool connector 120 may be replaced with another type of tool if propulsion is not required, such as, but not limited to, a sprayer or a vacuum.

It is believed that the use of the drive tool connector 120 may enable tools such as, but not limited to, ropes, brushes, sprayers, and video oscilloscopes to reach further into or under the pipe than when the propulsion device is not in use, which may enable a technician to clean pipe sections that are inaccessible or difficult to access due to various factors, including, but not limited to, pipe length and turns. Further, the cleaning device 100 may enable a technician to clean a pipe or tubing in one pass using multiple tools with a single line. Although the above embodiments are described as being used in cleaning applications, some embodiments may be implemented for use in various other applications, such as, but not limited to, painting, pneumatic tools, plumbing, mold repair, auto repair or repair, automotive details, electrical work, or other transactions requiring access to areas that are not accessible to an extension tool. Further, these embodiments may be used in locations other than pipes or ducts, including but not limited to pipes, behind appliances, in spaces between walls, in crawl spaces, in spaces between machines, or in any other difficult to access location. Further, the technique can be used for controlling a variety of operations of pressure operation, such as shower heads, sinks, sprayers, and the like.

One skilled in the art will readily recognize from the teachings of the present invention that a number of suitable tools may be attached to or integrated into a cleaning device that allows for the operation of a number of air, liquid or power tools. Further, these tools may be provided in a variety of different configurations for use in different types of applications. Fig. 2-5 illustrate some examples of such embodiments.

FIG. 2 is a partially transparent diagrammatic side view of a spray end of an exemplary multi-purpose device 200 that may be used as a self-propelled sprayer according to one embodiment of the invention. In this embodiment, the external hose 205 may be connected to a pressurized air or liquid supply. The air or liquid supply flows through the outer hose 205 to the drive tool connector 210 and is forced back through the channel 215 to push the device 200 forward. The inner hose 220 may be connected to a pressurized liquid supply that is discharged from the sprayer 225. Various different types of liquids may be discharged from sprayer 225 including, but not limited to, solutions for cleaning and/or sanitation, water, paint, or sealants.

FIG. 3 is a partially transparent diagrammatic side view of a spray end of an exemplary multi-purpose device 300 that may be used to spray multiple liquids in accordance with an embodiment of the present invention. In this embodiment, the external hose 305 may be connected to a pressurized liquid supply. The liquid supply flows to the spray tool connector 310 and is forced forward through the passage 315. The inner hose 320 may be connected to a pressurized liquid supply that is discharged from the sprayer 325. The device 300 may be implemented as a flexible hose-type assembly or may be implemented with rigid components to form a paint spray handle or wand, such as a paint spray gun and pressure gasket. The apparatus 300 may enable a user to perform a multi-step cleaning process using a single tool, as multiple solutions may be sprayed simultaneously or sequentially. For example, without limitation, the inner hose 320 may be connected to a water supply, while the outer hose 305 may be connected to a soap solution, typically to enable a user to clean a subject with the soap solution and then rinse the soap solution from the subject. It is contemplated that the liquid supply may be readily changed at a receiver near the bottom of the device 300 so that multiple liquids may be used in a single cleaning process, such as, but not limited to, a pre-cleaning solution, an engine degreaser, a tire cleaner, a window cleaner, an abrasive solution, a bleach, a disinfectant, or a mildewcide. Further, the device 300 may be used for applications other than cleaning. For example, without limitation, the device 300 may be used to water and fertilize vegetation, to spray soap and water while showering or washing dogs, or to spray paint in different colors. In addition, fire hoses may use this technology, allowing the "injection" of foaming agent into the fire hose so that the fire fighter simply sprays water and "water containing foaming agent (or similar product)" directly from the nozzle at the end of the hose. This will greatly reduce the cleaning of the hazardous fire extinguishing agent after a fire and enable the fire fighter to better control his environment.

FIG. 4 is a partially transparent diagrammatic side view of an exemplary multi-purpose device 400 in accordance with an embodiment of the present invention, which multi-purpose device 400 may be used as a self-propelled camera. In this embodiment, the outer hose 405 may be connected to a pressurized air supply. The air supply flows through the outer hose 405 to the drive tool connector 410 and is forced back through the channel 415 to push the device 400 forward. The inner hose 420 may be connected to the same air supply or a separate air supply or solution/paint/drain from an optional forward channel 425 for venting air to push debris, liquid solution for disinfection, or to drive another cleaning device such as a rope, brush, or similar device as previously described, and the cable 430 may pass through the inner or outer hose 420 to power a camera tool 435 such as, but not limited to, a still camera or video oscilloscope. In this embodiment, the camera tool 435 may be advanced by the drive tool connector 410 to a difficult to access location to typically enable a technician to view an area that may not have been previously accessible.

FIG. 5 is a partially transparent diagrammatic side view of an exemplary multi-purpose device 500 according to one embodiment of the present invention, the multi-purpose device 500 may be used as a cleaning and vacuuming system. In this embodiment, the external hose 505 may be connected to the vacuum channel 510 in the vacuum device and vacuum tool connector 515. The inner hose 520 may be connected to pressurized air or liquid discharged from the sprayer 525. It is believed that the cleaning and vacuum system can better clean less dirty surfaces when the air/liquid jet discharged from the atomizer 525 agitates or removes dust and debris from the surface to be cleaned prior to or simultaneously with the vacuum applied by the vacuum tool connector 515. In some applications, a liquid such as, but not limited to, water or a cleaning solution may be discharged through the sprayer 525 and evacuated along with debris through the vacuum tool connector. Non-limiting examples of such applications may include dental hygiene devices that combine pressurized water rinsing and suction in the same tool and use the pressurized water to rinse in an environment where excess water is not needed. Furthermore, the system can also be integrated into a domestic or workshop vacuum cleaner together with a compressed air supply system. The air supply may be redirected from the vacuum exhaust to the floor to be cleaned. The vacuum tool connector 515 may be made of rubber, plastic, or similar material that may be suitable for capturing debris and liquids.

Fig. 6A and 6B illustrate an exemplary cleaning device 600 having a technical control device capable of operating multiple tools, according to one embodiment of the present invention. Fig. 6A is a diagrammatic side view, partially transparent, and fig. 6B is a diagrammatic top view, partially transparent. In this embodiment, the cleaning apparatus 600 includes an inner hose 605 passing through an outer hose 610. A drive tool connector 615 and a hose connector 620 are located at each end of the outer hose 610 to typically enable the flow of air into the inner hose 605 and the flow of air into the outer hose 610 to be independently controlled. A compression fitting 625 may be used to seal the end of the inner hose 605 at the hose connector 620 at the point where the inner hose 605 passes through the hose connector 620. The drive tool connector 615 is located near the cleaning end of the cleaning apparatus 600 and includes an aperture 630 that allows air from the air chamber between the inner hose 605 and the outer hose 610 to be forced out of the back of the drive tool connector 615 to push the cleaning end of the cleaning apparatus 600 forward through the duct or conduit. In this embodiment, the inner hose 605 allows a pneumatic stirring device (such as, but not limited to, an air whip 635) to be controlled by the air within the inner hose 605. Air valves 640 and 645 in a control panel 650 at the end of a technician of the cleaning apparatus 600 allow the technician to control the flow of air to the drive tool connector 615 and air whip 635. Referring to FIG. 6B, the main air supply 655 enters the control panel 650 and is divided into an inner hose air supply 660 and an outer hose air supply 665. The flow of inner hose supply air 660 can be controlled by air valve 640 and the flow of outer hose supply air 665 can be controlled by air valve 645. For example, air valves 640 and 645 are shown as plug-in valves for preventing or allowing air flow through device 600. Alternate embodiments may include a variety of different types of controls including, but not limited to, switches, levers, or dials. The separate gas streams may be operated together or separately as desired. It is contemplated that the drive tool connector 615 and any additional tools may be operated using means other than air flow, such as, but not limited to, other flows of gas or liquid. In this embodiment, a threaded connector 670 on the drive tool connector 615 may enable tools such as, but not limited to, an air whip 635, other types of blending tools, cameras, sprayers, or vacuum heads to be connected to the cleaning apparatus 600. In addition, an electrically controlled device such as, but not limited to, a camera, a video oscilloscope, or a light may be connected to cleaning apparatus 600 in addition to or in place of an auxiliary tool operated by pressurized air or liquid. The power supply for the electronic control means may be provided by wires passing through the inner hose 605 or the outer hose 610.

In a typical use of the present embodiment, the cleaning device 600 may be used to clean a duct in an hvac system. The technician may first insert the cleaning device 600 into the cleaning end of the conduit, then turn on the air flow to the external hose 610 and use the air valve 645 to actuate the tool connector 615 to push the cleaning end of the cleaning device 600 through the conduit. The air flow to the inner hose 605 can also be opened through the air valve 640 so that the air whip 635 can agitate debris in the conduit as the cleaning tool 600 is moved down the conduit. Alternatively, the air flow to the inner hose 605 may remain closed until the cleaning end of the cleaning apparatus 600 reaches a desired position within the duct, at which point the technician may close the air flow to the outer hose 610 to stop forward movement of the drive tool connector 615 and open the air flow to the inner hose 605 using the air valve 640 to activate the air whip 635.

Fig. 7A, 7B, and 7C illustrate an exemplary after market accessory device 700 that may be connected to an existing device 705 for simultaneously propelling the existing device 705 and/or operating multiple devices, according to embodiments of the invention. Fig. 7A is a diagrammatic side view, partially transparent. Fig. 7B is a perspective side view, and fig. 7C is a rear view. In this embodiment, the apparatus 700 includes an air or liquid pressurized drive tool 710 connected to a supply hose 715, the supply hose 715 being capable of supplying pressurized air or liquid. Air or liquid is vented through the holes 720 in the back of the driving tool 710 to push the driving tool 710 forward. A notch coupled to the central bore 730 in the driver tool 710 may allow the cable 735 to be inserted into the driver tool 710. In some applications, the exit tool may comprise a hose or rigid tube to which the driving tool 710 may be attached rather than a cord. The driver tool 710 may be made of a flexible material, such as, but not limited to, rubber or plastic, which may make it easier for the driver tool 710 to be placed over the cord 735. Optionally, a belt 740 may also be wrapped around the cord 735 and the drive hose 715 to further secure the device 700 to the existing device 705. In alternative embodiments, the drive tool may be connected to existing equipment using a variety of suitable means, including but not limited to multiple straps, clamps, elastic bands, screws, and brackets.

In a typical use of this embodiment, once the driving tool 710 is connected to the existing equipment 705, a flow of air or liquid may be turned on to drive the tool 710 to advance the existing equipment 705 to a desired location. The flow of air or liquid may then be shut off so that the existing device 705 may be used at the desired location. The existing device 705 may be an electrical device such as, but not limited to, a video range or camera, or may be a device operated by pressurized air or liquid, such as, but not limited to, an air whip, a nebulizer, a vacuum. In applications where propulsion is not required, embodiments including tools other than drive tools may be integrated into the after-market accessory device.

Fig. 8A and 8b are side views of an exemplary tool attachment for the adjustable portion of a multi-purpose device 800 that may be used to adjust the length of a cleaning scrubbing cord, a control nozzle for propulsion, and/or the position of any tool on the device 800 for dispensing solution/paint/propulsion and inspection or machinery in accordance with processes/operations of embodiments of the present invention. In this embodiment, the external hose 815 may be connected to a pressurized air supply. This air supply is delivered to the air wiper connector and may be forced forward by the wiper 830 within the adjustable sheath 860. The internal hose 825 may be connected to the same air supply to be exhausted from the drive tool attachment 810 and push the apparatus 800 forward backwards through the channel 820. The apparatus 800 may enable a user to perform a multi-step cleaning process using a single tool, as the tool 800 may be adjusted to fit and reach a variety of sizes of cavities/spaces to be cleaned/inspected. For example, and without limitation, adjustable sheath 860 may be adjustable in a forward position, as shown at 8a, to shorten the length of the whip used to clean smaller tubes, or in a rearward position, as shown at 8b, for larger cavities, or anywhere in between, for different sized tubes/cavities. A flexible portion of hose 840 may be attached to allow the tool to be pulled around the corner with the driving tool attachment. Further, the apparatus 800 may be used for applications other than cleaning. For example, without limitation, the attachment 860 may be used to adjust the illuminated display for a sharper image, adjust the distance between tool attachments, even inflate a balloon to prevent air or liquid flow beyond a certain point, or remove/move material blocking a duct or similar environment. The balloon may enable an operator to grasp the cavity wall and allow greater control/force when cleaning, moving, or satisfying any other relevant needs using a pneumatic, electrical, or other pressure driven system.

Fig. 9a and 9b illustrate an exemplary assembly 900 that includes a rigid support member incorporated in accordance with an embodiment of the present invention. Fig. 9a is a cross-sectional side view of the hose assembly 900. Fig. 9b is a cross-sectional view of the hose assembly 900. In this embodiment, the hose assembly 900 may include a rigid/resilient support rod 930 inserted between the inner and outer hoses 910, 920 to allow the user to push the tool down larger and longer cavities/chases and/or to a distance where flexibility is desired, and rigid systems are not available. The support bar 930 compensates for the backlash effect of the inner hose 910 and the outer hose 920. Furthermore, when manufactured for greater stability and rigidity, support member 930 may be embedded in inner hose 910, outer hose 920, or dual hose fig. 10, without limitation. The support rods may be made of metal, fiberglass, plastic, or similar composite materials.

FIG. 10 is a cross-sectional view of a hose according to an embodiment of the present invention. In the embodiment shown, there are two chambers, first chamber 1020 and second chamber 1030, one (1) hose 100. The dedicated connector may be shaped to receive the individual chambers 1020 and 1030. In addition, the chambers 1020 and 1030 may be sized differently to allow for the flow of various solutions, air, and/or controlled substances, including but not limited to solids, sand blast, and the like.

Figure 11 is an intermediate in-line connector 1110 that allows the air, liquid or solution to be dispersed through the connector bore 1140 along the length of the hose assembly as desired. The in-line coupler 1110 may be twisted or "turned on/off" as needed in order for the pneumatic stand to pull the assembly farther or to spread the compression elements provided. Connector 1140 divides the outer hose into two parts, assemblies 1120 and 1130 and allows pressurized air or fluid to flow out through holes 1140, whips or similar applications. The intermediate in-line connector 1110 may allow the air, liquid or solution to be dispersed along the length of the hose assembly as desired.

Those skilled in the art will readily appreciate from the teachings of the present invention that some embodiments may be implemented in configurations other than those described above. For example, without limitation, some embodiments may be implemented as stand-alone devices having a side-by-side hose assembly design with connectors that perform similar functions to those described above. These embodiments look similar to the embodiments shown by way of example in fig. 7A, 7B and 7C, but do not attach to existing equipment. Other embodiments may include two or more separate connectors that may exhaust gas or liquid with equal distribution around the hose or assembly. These connectors may be similar to the drive tool connectors described in some of the embodiments above, and may vent gas or liquid from different directions. However, other embodiments may include hoses, tubes, and cords that are not circular or straight in shape, including but not limited to square tubes, flat cords, flexible hoses, tapered hoses, and ridged hoses.

All functions disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative functions, which may be performed by the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each function disclosed is one example only of a generic series of equivalent or similar functions.

It is noted that, according to U.S. Law, volume 35, article 112(1), all claims must be fully disclosed in this patent specification and any material known to those skilled in the art need not be explicitly disclosed. However, article 112(6) of volume 35 of the united states code requires that the structure corresponding to the functional limitations explained according to section 112(6) of volume 35 of the united states code must be explicitly disclosed in the patent specification. Furthermore, the examination policy of the U.S. patent and trademark office for preliminary processing and searching for prior art under the broadest interpretation of the "mean" patent claim limitations means that the most extensive preliminary examination of the functional limitations in 112(6) must be conducted to support the legally valid examination of the policy of the U.S. patent and trademark office for the broadest interpretation of the "mean" claim. The united states patent and trademark office will thus find a multiplicity of prior art documents, including disclosure of specific structures and elements suitable as corresponding structures, to meet all of the functional limitations in the claims below, which are disclosed in the above patent specification in accordance with article 112(6) of volume 35 of the united states code, which is not explicitly stated in the corresponding structure. Thus, for any inventive element/structure corresponding to a functional requirement limitation, the following patent claims, as not explicitly disclosed in the foregoing patent specification, but as found in the patent and/or non-patent documents found during a search of the United states patent and trademark office, are to be construed in relation to article 35, volume 112, 6 of the United states code; applicant incorporates herein by reference all such functionally corresponding structures and associated enabling materials in order to provide a clear structure for implementing the required functional means. Applicants have requested that the factorers found during the prosecution of any claim interpreters and/or patent allowability be correctly identified and incorporated only in the part of those documents found during the most extensive interpretation search under the restrictions of article 112(6) of volume 35 of the united states codex, during the normal search of the united states patent and trademark office found in at least one of the patent and/or non-patent documents, or provided to the office during prosecution. Applicants should also incorporate bibliographic citations to identify all such documents, including patent structures and associated enabling materials corresponding to the functions listed in the table of trademark office 892, or similarly, statements of disclosure information provided by the U.S. patent office or applicants or any third party. Applicants also reserve the right to subsequently modify the present application to explicitly include a reference to such documents and/or to explicitly include a corresponding functional structure incorporated by reference above.

Thus, for inventive elements/structures not specifically disclosed in any of the above patent specifications, explained in section 112(6) of volume 35 of the U.S. code, corresponding to the limitations of the functional claims in the following claims, applicants have specified which documents and materials should include other missing disclosures, and have specified which portions of such patent and/or non-patent documents should be incorporated by reference in order to meet the disclosure requirements of section 112(6) of volume 35 of the U.S. code. Applicants note that all of the above identified documents, which are incorporated by reference to meet the requirements of section 112(6) of volume 35 of the united states codex, must have a filing and/or release date prior to the instant application date and are therefore valid prior to the instant application being incorporated by reference.

Having fully described at least one embodiment of the invention, other equivalent or alternative methods of implementing an apparatus comprising a plurality of tools in an assembly according to the invention will be apparent to those skilled in the art. The various aspects of the present invention have been described above in an illustrative manner, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed. The particular implementation of the device may vary depending on the particular context or application. By way of example and not of limitation, the above-described device is mainly intended for applications in industrial and commercial type setting implementations; however, similar techniques may alternatively be applied to non-industrial applications, including but not limited to, hands-on-the-self applications, personal care applications, and entertainment applications, and such implementations of the invention are contemplated as within the scope of the invention. Accordingly, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the following claims. It will be further understood that not all embodiments disclosed in the foregoing specification necessarily meet or achieve each and every object, advantage, or improvement described in the foregoing specification.

The patent claims elements and steps herein may have been numbered and/or alphabetized for the sole purpose of facilitating readability and understanding. Any such numbers and letters are not intended, and should not be used, per se, to indicate the order of elements and/or steps in the claims.

The corresponding structures, materials, acts, and equivalents of all means, step, and function elements in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed.

The corresponding structures, materials, acts, and equivalents of all means or step plus function elements in the claims below are intended to include any structure, material, or element for performing the function in combination with other claimed elements as specifically claimed. The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the invention. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Furthermore, if longer lengths are desired or rigid wires are used, an "in-line" connector with twist or quick connect options can be added to the main starter cord to increase the length of the assembly. In addition, additional drive connectors may be used to push longer hose assemblies from the "middle" portion of the hose assembly. Furthermore, the hose assembly may be formed from a plurality of drive nozzle connectors along the length of the hose assembly (or similar assembly), which may be twisted (or activated by the aforementioned method) so that the nozzles can push the pipeline from the intermediate section as it is inserted into the pipe or cavity to be treated.

The abstract is provided to comply with the requirements for an abstract in section 1.72(b) of 37c.f.r. to enable the reader to ascertain the nature and gist of the technical disclosure.
