Overview of the System

FIG. 1a is a simplified schematic diagram of a training system, generally designated 100. In some embodiments, the use of system 100 helps to enable training center 40 to meet the requirements of regulatory agencies. Alternatively or additionally, in some embodiments, the use of the system 100 facilitates the standardization of performance data from trainees 4 of different training centers 40 to facilitate objective comparisons of such performance data.

For clarity, a single training center 40 and a single template source 10 are shown, although the system 100 may include multiple training centers 40 and template sources 10. Similarly, the training center 40 is depicted as including a single handheld target, a single trainer 2, and a single trainee 4, although a typical training center 40 would include a plurality of handheld targets, trainees 2, and trainees 4. Similarly, the handheld target 30 is depicted as being loaded with a single performance template 20, although it may be loaded with multiple performance templates 20 sequentially or simultaneously.

The coach 2 and the student 4 are not part of the system, but are shown in fig. 1a as they interact with each other (6) and with the system.

In the depicted embodiment, the training center 40 issues a request 42 to the template source 10. According to various exemplary embodiments of the present invention, the template source 10 includes, but is not limited to, sports associations, recognized champions, and therapeutic practitioners. In response to the request (42), the template source 10 provides (12) one or more digitally encoded performance templates 20 to the training center 40. In some exemplary embodiments of the invention, a template 20 is provided on a tangible machine-readable medium. Alternatively or additionally, in some embodiments, the template 20 is transmitted as a digital file across a network (e.g., the internet).

In some exemplary embodiments of the invention, the template 20 is used by loading the digital instructions 22 into computer memory in the handheld target 30. According to various exemplary embodiments of the invention, the loading of instructions 22 is done before or during training (e.g., by Wi-Fi dataflow).

The instructions 22 are loaded 22 into the handheld target 30. The trainer 2 holds the target 30 and the trainee 4 attempts to hit the target in accordance with the trainee's instructions 22b transmitted through the target 30. Alternatively or additionally, in some embodiments, the trainer 2 manipulates the target 30 according to a trainer directive 22a, wherein the trainer directive 22a is also transmitted via the target 30.

In the depicted embodiment, the interaction (6) between the trainer 2 and the trainee 4 is largely controlled by the target 30 through the instructions 22a and 22 b.

Fig. 1b is a simplified schematic illustration of a handle portion (generally designated 31) of a handheld striking target (see 30 in fig. 1) according to some exemplary embodiments of the present invention. For purposes of this specification and the appended claims, the terms "handheld striking target", "handheld target" and "target" do not include equipment mounted on a pole or platform.

The depicted embodiment includes a principal 102, the principal 102 containing electronic components that cooperate to collect data related to student performance during training as specified by the digital format performance template 20 (fig. 1a), where the digital format performance template 20 is stored in the memory 132 of the CPU 130. In addition, these electronic components provide prompts (labeled 22a and 22b, respectively, in FIG. 1a) to the coach and/or student via the associated user interface, as described in more detail below.

In the depicted embodiment, the electronic component includes an accelerometer 110 for providing a first data output signal 112. Signal 112 indicates the striking force imparted on strike pad 155.

In the depicted embodiment, the electronic assembly further comprises an altimeter 120 for providing a second data output signal 122. In some embodiments, the altimeter function is provided by an ultrasonic transducer. In other exemplary embodiments of the invention, the altimeter function is provided by a laser rangefinder. In some implementations, the altimeter 120 is positioned in the handle so that the altimeter 120 can send a signal 121 to the floor and receive a reflection 123 of the signal from the floor. In the depicted embodiment, the handle is equipped with a rotation mechanism (indicated by dashed line R-R). According to the depicted embodiment, the coach grasps the handle on the side of line R-R opposite the height gauge 120. The rear of the handle containing the height gauge 120 is rotated at line R-R so that the signal 121 is aimed vertically at the floor. In some embodiments, the weight of the altimeter 120 is sufficient to cause rotation at R-R. In other exemplary embodiments of the invention weights (not shown) are additionally mounted to ensure proper rotation.

In the depicted embodiment, the first and second data output signals 112 and 122 are received and stored by the CPU 130. In some implementations, the first and second data output signals 112 and 122 are stored in the memory 132. Alternatively or additionally, in the depicted embodiment, a power source (depicted as a battery 140) provides power to the accelerometer 110, the altimeter 120, and the CPU 130. In some embodiments, the CPU130 converts (22 in fig. 1a) the digital format performance template instructions into prompts (labeled 22a and 22b, respectively, in fig. 1a) for the trainer and/or trainee and communicates these prompts through an associated user interface.

In some embodiments, handle 31 includes a connector 150 that connects to a strike pad (partially shown as 155). In some embodiments, the handle 31 is attached to or integrally formed with a pad (partially shown as 155).

In the depicted embodiment, the handle 31 includes a display 160. According to various exemplary embodiments of the present invention, the display 160 includes an LCD panel and/or an LCD indicator and/or an audio output device (e.g., a buzzer or chime). In some exemplary embodiments of the invention, the display 160 serves as a coaching interface. According to these embodiments, a prompt 22a is displayed on the display 160 to indicate to the coach when and how to move the targets 31 for striking according to the instructions 22 in the digital format performance template 20 read by the CPU 130.

In the depicted embodiment, the handle 31 includes one or more waveguides 170 extending therefrom. In the depicted embodiment, the handle 31 includes one or more light sources 172. In some embodiments, the waveguide 170 is provided in the form of an optical fiber. In some embodiments, the waveguide conducts light to one or more trainee facing displays 173 in the striking targets 155. For example, in some embodiments, the target 155 has a display facing the left trainee and a display facing the right trainee. In some embodiments, the display facing the trainee comprises a transparent or translucent panel that is significantly brighter as the light from the light source 172 propagates through the waveguide 170 (e.g., an optical fiber). In some exemplary embodiments of the invention, light from the light source 172 gives a cue 22b on the trainee interface.

In the depicted embodiment, the handle 31 includes a connector 180 that is compatible with an external charging power source. According to various exemplary embodiments of the present invention, the connector 180 is configured as a USB port or a DC jack. The connector 180 is connected to an external power source to charge the power source 140.

In some exemplary embodiments of the invention, the CPU130 comprises a clock 134 and a time stamping module 136, the time stamping module 136 being adapted to apply time stamps to the first data output signal 112 and the second data output signal 122. Alternatively or additionally, in some embodiments, the timestamp module 136 is adapted to apply a timestamp to the instructions 22 and/or 22a and/or 22 b. In some exemplary embodiments of the invention, the time stamp signal is stored in the memory 132.

Alternatively or additionally, in some embodiments, the handle 31 includes a trainer input interface 190 positioned to receive commands from a hand holding the handle. According to various exemplary embodiments of the invention, interface 190 comprises a touch screen and/or buttons and/or switches. In some embodiments, the trainer input 190 is configured to accept a small number of input commands (e.g., "start digital format performance template," "next template," "previous template," "pause," and "stop"). Alternatively or additionally, in some embodiments, each workout is scored in a digital format performance template via the coaching input of the interface 190. According to these embodiments, these scores are stored in the memory 132 along with other performance data in the memory 132.

In some implementations, each of the exercises in the digital format performance template is time stamped by the time stamping module 136 and stored by the memory 132. This practice helps evaluate the trainee based on the difference in delay between giving the trainee prompt 22b (e.g., from light 172) and recording the blow by accelerometer 110 (again with a time stamp). Alternatively or additionally, for each training in the digital format performance template read from the memory 132, this approach facilitates evaluation of the trainee as a function of the kick height (altitude) (also with a time stamp) indicated by the signal 122 of the altimeter 120.

In the depicted embodiment, the handle 31 includes a data port 181. According to various exemplary embodiments of the present invention, port 181 is used to load instructions 22 from template 20 (see also fig. 1a) onto memory 132 in CPU130 of target 30 and/or for the entry of trainee 4 with a particular target prior to training. The trainee login data is also stored in the memory 132 of the CPU 130.

In the depicted embodiment, the handle 31 includes an audio output unit 183, the audio output unit 183 receiving audio output signals from the CPU 130. According to various exemplary embodiments of the present invention, the audio output unit 183 is configured as a speaker or a BR/EDR bluetooth device, which first receives a connection request from a headset and then transmits an audio signal to the headset.

Exemplary method

Fig. 2 is a simplified flow diagram of a method for providing body movement instructions, generally designated 200, according to some exemplary embodiments of the present invention.

The depicted exemplary method 200 includes loading (210) a digital format performance template into a memory of a handheld target. In some exemplary embodiments of the invention, the loaded instructions are processed by a CPU in the target to generate coach instructions and trainee instructions (labeled 22a and 22b, respectively, in FIG. 1 a). In other exemplary embodiments of the present invention, the coach instructions and student instructions (labeled 22a and 22b, respectively) are loaded directly and presented simply by the CPU in the target.

In the depicted embodiment, the method 200 includes presenting (220) a first set of instructions to the coach via a first user interface and presenting (230) a second set of instructions to the student as a graphical prompt via a second user interface. Exemplary first and second interfaces are shown in FIG. 1b as screen 160 and light 172.

In the depicted embodiment, the method 200 includes providing (240) a separate graphical prompt to the coach via a first user interface (e.g., screen 160). In some exemplary embodiments of the invention, these prompts differ in content and/or time from the prompts presented to the trainee. For example, in some embodiments, a graphical prompt in the form of an up arrow is presented on the screen 160 until the target is raised to the appropriate height. In terms of timing, the learner must be given a graphic prompt indicating "strike" after the arrow appears on the screen 160. A prompt to the trainee indicates (e.g., via light 172) when the trainee has hit. In some embodiments, lights on the left and right sides of the target visually indicate to which side the trainee is to hit. When the trainee cue appears, the position of the target indicates the appropriate strike height. In some exemplary embodiments of the invention, different strike types are indicated by different colored lights in the student prompt.

Alternatively or additionally, in some embodiments, the method 200 includes providing (250) an audible prompt to the coach via the first user interface. According to these embodiments, the first user interface includes a trainer headset that receives audio output from audio output source 183 (FIG. 1 b). According to various exemplary embodiments of the invention, the headset is a wireless headset (e.g., a bluetooth headset) or a wired headset.

In some exemplary embodiments of the invention, the loading comprises data transfer using one or more communication protocols such as bluetooth, Near Field Contact (NFC), Universal Serial Bus (USB), ethernet, and Wi-Fi.

Alternatively or additionally, in some embodiments, the digital format performance template is provided by at least one entity including, but not limited to, sports associations, recognized champions, and therapeutic practitioners. In some embodiments, templates provided by a particular entity are grouped (e.g., waistband colors corresponding to a particular martial arts). In some embodiments, each set of included templates has a hierarchy of increasing difficulty.

In some embodiments, each template includes a series of exercises arranged in a particular order and/or having a particular time sequence.

Exemplary virtual Competition

Referring again to fig. 1, 3, some embodiments of the invention relate to virtual tournaments. In a virtual competition, the same digital format performance template 20 (fig. 1) is loaded into the memory of a plurality of handheld targets 30 located at a plurality of locations, such as training center 40. Performance data 322 (fig. 3, e.g., collected in DB 310) is then collected for individual competitors (e.g., trainee 4, see fig. 1), and these competitors execute the same digital format template 20 at multiple locations 40 at discrete time intervals. According to these embodiments, the search engine 340 provides an output 342 of performance data 322 for at least some of the individual competitors (who are classified on a common display according to rank and student ID 312 at the plurality of locations 40) in response to a query 341, the query 341 being required to present the student ID 312 and a particular template 320 (e.g., 2019 California tournament, Green Banner). According to various exemplary embodiments of the present invention, the common display may be viewed by applications on smartphones or tablets and/or display panels located at multiple locations 40.

Exemplary size and weight limitations

Referring again to fig. 1b, the altimeter 120, accelerometer 110, CPU130 and power supply 140 are all mounted in the handle 31 of the target. Since the handle 31 will be held and moved by the trainer during training, size and weight limitations are placed on each component.

For this reason, commercially available components having weights of 1 gram, 2 grams, 5 grams, 7 grams, or 10 grams, respectively, or moderate or less grams, are optionally selected for use in various embodiments of the present invention.

For example, in some embodiments, the combined weight of the altimeter 120, the accelerometer 110, the CPU130, and the power source 140 is less than 50 grams, less than 40 grams, less than 30 grams, less than 20 grams, or less than 10 grams, or is a moderate or lesser number of grams.

Exemplary Power Limit

In some embodiments, power source 140 is a battery. In addition to being limited by the weight mentioned above, the battery must also have a sufficient life to power other components during training periods of 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes or 60 minutes or medium or longer.

Alternatively or additionally, batteries with short charging times relative to the training period are used in some embodiments. For example, if the charging time of the power source 140 is less than 60 minutes, a trainer performing training for 60 minutes may use two taekwondo oars equipped with the handle 31 indefinitely. According to these embodiments, after each workout, the coach replaces the paddle in his hand with the paddle in the charger.

Alternatively or additionally, in some embodiments, the configuration of other components of the system helps to extend the life of the battery.

For example, low power elements such as LEDs are used in the display 160 and/or the light sources 172 to help reduce power consumption, thereby extending battery life. Alternatively or additionally, in some embodiments, the light source 172 is configured to have a duty cycle of less than 100% to further reduce power consumption.

Alternatively or additionally, for example, if the altimeter 120 only transmits the signal 122 in response to an input from the user interface 190, the power consumption of the altimeter may be reduced, thereby helping to extend battery life.
