Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 61/831,617, filed Jun. 6, 2013 by the present inventors.

BACKGROUND

The present disclosure relates to providing immediate feedback to athletes during sports training. Specifically, the disclosure relates to sports that involve kicking a ball. Some examples are soccer, American football, and rugby.
In a kicking sport such as soccer, there may be multiple kicking techniques. Each kicking technique may involve an athlete making contact with a ball using a specific surface of a shoe. However, a novice athlete may tend to make contact with the ball using a suboptimal surface of the shoe.
For example, in soccer, one such kicking technique is called a straight kick. In a straight kick, an athlete kicks a ball with a top surface of a shoe. An amateur athlete may attempt a straight kick but incorrectly strike the ball with a forward tip of the shoe. This may reduce the accuracy and power of the kick. In some cases, this may even cause injury to the athlete.
Many different devices have been proposed to train athletes to kick a ball with specific surfaces of a shoe. Prior devices may provide auditory feedback, visual feedback, or both auditory and visual feedback when an athlete uses an optimal surface of a shoe. Some devices that provide auditory feedback are disclosed in U.S. Pat. No. 4,711,043 (Johnson et. al), U.S. Pat. No. 5,433,437 (Dudley), U.S. Pat. No. 5,897,446 (Krause & Wiseman), and U.S. Pat. No. 6,808,462 (Snyder et. al).
However, auditory feedback may not provide physical reinforcement to aid kinesthetic learning. In other words, auditory feedback may not provide a physical sensation to help an athlete associate his or her method of performing a particular kicking technique with a correct execution of the kicking technique. Additionally, auditory feedback may be problematic in a group training setting. For example, auditory feedback from an athlete's device may confuse or distract other athletes who are practicing nearby.
Likewise, visual feedback may not provide physical reinforcement to aid kinesthetic learning. Additionally, visual feedback near an athlete's foot may encourage the athlete to look down at his or her foot after a kick. Looking down may be distracting and undesirable in many kicking techniques.

SUMMARY

To overcome these deficiencies, a device constructed in accordance with an embodiment of the present disclosure may include one or more ball impact sensors, operationally coupled to one or more tactile feedback components. The sensors may be positionable on one or more surfaces of a shoe. The device may generate a tactile sensation when one or more sensors detect a ball impact.
A device constructed in accordance with another embodiment of the present disclosure may include one or more ball impact sensors, operationally coupled to one or more circuits. The one or more circuits may generate a tactile sensation in response to a ball impact.
In accordance with yet another embodiment of the present disclosure, a method of enhancing performance in kicking sports may include recognizing a ball impact on one or more surfaces of a shoe, producing tactile feedback related to the ball impact, and conveying the tactile feedback to an individual.
A device constructed in accordance with an embodiment of the present disclosure may produce tactile feedback, which may provide several advantages over auditory feedback or visual feedback. Tactile feedback may provide physical reinforcement to aid kinesthetic learning. In other words, tactile feedback may provide a physical sensation to help an athlete associate his or her method of performing a kicking technique with a correct execution of the kicking technique. Furthermore, tactile feedback may enable a discrete training experience, since tactile feedback may only be sensible to the athlete using the device. Additionally, the athlete may maintain concentration because he or she may not need to look down at his or her foot after the kick to receive feedback. Thus, tactile feedback may enhance an athlete's engagement and focus during a practice session.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Structure of the First Embodiment

FIGS. 1 through 8 show aspects of a device 1 constructed in accordance with a first embodiment of the present disclosure.
FIG. 1 shows a top view of device 1. Device 1 includes an assembly 10 for releasably positioning device 1 on a shoe. Assembly 10 includes a pouch 11, a strap 12, and a strap 13.

FIG. 3 shows device 1 operationally attached to a soccer shoe 20. Assembly 10 is releasably positioned on soccer shoe 20. Pouch 11 sits on a top surface 21 a of shoe 20, above a shoelaces component 22. Straps 12 and 13 wrap around shoe 20. Top side 12 a of strap 12 attaches to bottom side 13 b of strap 13 under a sole 23 of shoe 20.
FIG. 4 shows pouch 11 in contact with a soccer ball 30.
FIG. 5 shows a top view of device 1. Pouch 11 is an enclosure, which holds a circuit 40. Circuit 40 includes a circuit board 40 a. A tactile switch 41 is mounted on a top surface 40 b of circuit board 40 a.
FIG. 6 shows a top perspective view of circuit 40. Like FIG. 5, FIG. 6 depicts tactile switch 41 mounted on top surface 40 b of circuit board 40 a. Additionally, FIG. 6 partially shows a battery retainer 42 and a pancake style vibrating motor 43 mounted on a bottom surface 40 c of circuit board 40 a.
FIG. 7 shows a bottom perspective view of circuit 40. In addition to battery retainer 42 and vibrating motor 43, a capacitor 45, an NPN BJT transistor 46, and a resistor 47 are mounted on bottom surface 40 c of circuit board 40 a. Battery retainer 42 holds a coin cell battery 44.
FIG. 8 shows a circuit diagram of circuit 40. A positive terminal 44 a of battery 44 connects to a terminal 41 a of tactile switch 41 and a terminal 43 a of vibrating motor 43. A terminal 41 b of tactile switch 41 connects to a terminal 47 a of resistor 47 and a positive terminal 45 a of capacitor 45. A terminal 43 b of vibrating motor 43 connects to a collector terminal 46 a of NPN BJT transistor 46. A terminal 47 b of resistor 47 connects to a base terminal 46 b of transistor 46. A ground terminal 45 b of capacitor 45 and an emitter terminal 46 c of transistor 46 connect to a ground terminal 44 b of battery 44.

Operation of the First Embodiment

To use device 1, an athlete first selects a kicking technique to practice. Then, the athlete attaches device 1 to a shoe, positioning pouch 11 on an optimal surface for the selected kicking technique. Next, the athlete performs the selected kicking technique, making contact with a ball. If the athlete kicks the ball using the optimal surface of the shoe, device 1 provides a tactile sensation as feedback. If the athlete kicks the ball using a suboptimal surface of the shoe, device 1 does not provide tactile feedback. Thus, the athlete is able to determine whether or not he or she executed the selected kicking technique using the optimal surface of the shoe. Without supplementary tactile feedback, the athlete may find it difficult to determine whether or not he or she executed the selected kicking technique using the optimal surface of the shoe.
If the athlete receives tactile feedback from a kick, he or she may attempt to receive tactile feedback from subsequent kicks. In order to continue receiving tactile feedback, the athlete may maintain his or her method of performing the selected kicking technique and may continue to kick the ball with the optimal surface of the shoe. If the athlete does not receive tactile feedback from a kick, he or she may attempt to receive tactile feedback from subsequent kicks. In order to receive tactile feedback, the athlete may modify his or her method of performing the selected kicking technique to use the optimal surface of the shoe. By repeatedly kicking the ball with the optimal surface of the shoe, the athlete may build proficiency in the selected kicking technique.
When an athlete performs a selected kicking technique, the ball may move along a certain flight path. Device 1 may be designed to minimally affect the flight path of the ball. If a device protrudes significantly from a shoe, it may alter the shape of the shoe's contact surfaces with the ball. Altering the shape of the shoe's contact surfaces may undesirably affect the flight path of the ball. Thus, it may be advantageous to minimize the protrusion of device 1 from the shoe. For example, device 1 may be manufactured to protrude no more than 0.75 inches from the shoe. Manufacturing device 1 with flexible materials may aid in minimizing the protrusion of device 1. Additionally, manufacturing device 1 with low-profile electronic components such as pancake-style vibrating motor 43 may further aid in minimizing the protrusion of device 1.
In FIG. 3, an athlete has attached device 1 to shoe 20 by positioning assembly 10 on shoe 20. Specifically, an athlete has wrapped straps 12 and 13 around the shoe and pressed hook tape surface 12 a and loop tape surface 13 b together to create a releasable bond. The hook and loop tape releasable bond makes assembly 10 adjustable to fit a plurality of shoe sizes. Other types of releasable bonds may also make assembly 10 adjustable to fit a plurality of shoe sizes.
In FIG. 3, the athlete has positioned pouch 11 on top surface 21 a of shoe 20 in order to practice a soccer kicking technique called a straight kick. This positioning ensures that device 1 will provide tactile feedback when the athlete kicks a ball using top surface 21 a of shoe 20. Other kicking techniques may use other surfaces of shoe 20. To practice other kicking techniques, the athlete may position pouch 11 on a different surface of shoe 20.
In FIG. 4, the athlete is in the midst of correctly executing a straight kick. Device 1 comes in contact with ball 30 at the approximate position of pouch 11. As shown in FIG. 5, circuit 40 and its mounted tactile switch 41 are located inside neoprene pouch 11. Since pouch 11 is made from a cushioning material such as neoprene, pouch 11 dampens the force of the ball impact on circuit 40 and its components. When device 1 comes in contact with ball 30, tactile switch 41 acts as a ball impact sensor. The contact with ball 30 depresses tactile switch 41. When depressed, the switch changes state from open to closed. This begins the electrical operation of circuit 40.
FIG. 8 shows tactile switch 41 in an initially open state. When the switch changes to a closed state, electric current flows into capacitor 45 and through resistor 47 into base terminal 46 b of transistor 46. Because there are no components with significant resistance between positive terminal 44 a of battery 44 and positive terminal 45 a of capacitor 45, the capacitor quickly charges up to full capacity. A current on base terminal 46 b of transistor 46 turns on the transistor and causes current to flow between collector terminal 46 a and emitter terminal 46 c. When current flows through transistor 46, current also flows into vibrating motor 43. Vibrating motor 43 acts as a tactile feedback component. When current flows through the vibrating motor, it vibrates. This creates a tactile sensation for the athlete.
After the momentary contact between pouch 11 and ball 30, the ball no longer depresses tactile switch 41 and the switch changes state from closed back to open. Then, capacitor 45 begins to discharge through resistor 47 into base terminal 46 b of transistor 46. This keeps current flowing between collector terminal 46 a and emitter terminal 46 c of transistor 46 and through vibrating motor 43 for a short duration until capacitor 45 is discharged. This results in a short duration of tactile sensation for the athlete.
Many different circuits with different components than circuit 40 may be designed to produce similar results as circuit 40. For example, instead of using coin cell battery 44, a circuit may use a thin flexible battery or a cylindrical cell battery. Additionally, a circuit may use a rechargeable battery or a non-rechargeable battery. Instead of using pancake style vibrating motor 43, a circuit may use a cylindrical vibrating motor. Instead of using a single tactile switch 41, a circuit may use multiple tactile switches. Instead of using one or more tactile switches, a circuit may use one or more piezoelectric sensors. Instead of using an NPN BJT transistor 46, a circuit may use a MOSFET transistor. Instead of using a circuit board to connect the components, a circuit may use wires to connect the components. Instead of using a circuit board to keep the components colocated, a circuit may use shrink tubing to keep the components colocated.
Furthermore, a circuit may be designed to produce different patterns of tactile feedback. For example, instead of producing a short duration of continuous vibrating feedback, a circuit may produce a short duration of intermittent vibrating feedback.
Additionally, while device 1 provides tactile feedback when an athlete kicks a ball using an optimal surface of a shoe for a selected kicking technique, device 1 may be adapted to provide tactile feedback when an athlete kicks a ball using a suboptimal surface of the shoe for the selected kicking technique. In this case, the athlete may interpret a tactile sensation as negative feedback. The tactile sensation may indicate that he or she should modify his or her method of performing the selected kicking technique in order to use the optimal surface of the shoe.
While device 1 has been illustrated in terms of improving performance in the sport of soccer, device 1 may be capable of improving performance in other kicking sports including, but not limited to, American football and rugby.

Structure of the Second Embodiment

FIG. 9 shows a shoe 50 constructed in accordance with a second embodiment of the present disclosure. Shoe 50 includes a top surface 51 a, an outstep surface 51 b, and an instep surface 51 c. Shoe 50 further includes a tongue 52 specially adapted to hold circuit 40.

Operation of the Second Embodiment

Shoe 50 is adapted to practice a straight kick in soccer. When an athlete wearing shoe 50 strikes a ball using top surface 51 a of shoe 50, the ball presses against tongue 52, which depresses tactile switch 41. Like in the operation of device 1, depressing tactile switch 41 triggers a short duration of tactile feedback for the athlete.
Shoe 50 may be adapted to practice additional kicking techniques by embedding circuit 40 or an equivalent circuit in additional surfaces of the shoe. For example, circuit 40 may be embedded in outstep surface 51 b so that an athlete may practice outstep pass kicks. Similarly, circuit 40 may be embedded in instep surface 51 c so that an athlete may practice instep pass kicks. If shoe 50 is adapted to not include a tongue 52, circuit 40 may be embedded directly in top surface 51 a. Circuit 40 or an equivalent circuit may be embedded in other surfaces of shoe 50 for practicing other kicking techniques.

Structure of the Third Embodiment

FIGS. 10, 11, and 12 show a device 60 constructed in accordance with a third embodiment of the present disclosure. Device 60 includes a strap assembly 61 for releasably positioning device 60 on shoe 20. Strap assembly 61 is constructed with a stretchable material such as elastic, rubber, or silicone. Strap assembly 61 includes a strap 61 a and a pouch 62 attached to strap 61 a. Pouch 62 holds circuit 40.

Operation of the Third Embodiment

To use device 60, an athlete first selects a kicking technique to practice. Then, the athlete slides strap assembly 61 over shoe 20, positioning pouch 62 on an optimal surface of shoe 20 for the selected kicking technique. In FIG. 10, the athlete has positioned pouch 62 on top surface 21 a of shoe 20 in order to practice a straight kick. When the athlete strikes a ball using top surface 21 a of shoe 20, the ball presses against pouch 62, which depresses tactile switch 41. Like in the operation of device 1, depressing tactile switch 41 triggers a short duration of tactile feedback for the athlete.
Like device 1, device 60 may be positioned on different surfaces of shoe 20 in order to practice different kicking techniques. For example, in FIG. 11, the athlete has positioned pouch 62 on an outstep surface 21 b of shoe 20 in order to practice an outstep pass kick. In FIG. 12, the athlete has positioned pouch 62 on an instep surface 21 c of shoe 20 in order to practice an instep pass kick.

Structure of the Fourth Embodiment

FIG. 13 shows a device 70 constructed in accordance with a fourth embodiment of the present disclosure. Device 70 includes a strap assembly 71 for releasably positioning device 70 on shoe 20. Strap assembly 71 includes a stretchable strap 71 a. Unlike strap assembly 61, strap assembly 71 includes a plurality of pouches 72 a, 72 b, and 72 c. Each pouch 72 a, 72 b, and 72 c is attached to strap 71 a; each pouch is spaced apart from the other pouches, and each pouch holds an instance of circuit 40.

Operation of the Fourth Embodiment

Unlike an athlete using device 60, an athlete using device 70 does not select a single kicking technique to practice before using the device. Instead, the athlete properly positions device 70 and may practice straight kicks, outstep pass kicks, and instep pass kicks without repositioning device 70.
To properly position device 70, the athlete slides strap assembly 71 over shoe 20, positioning pouch 72 a on top surface 21 a of shoe 20. This positioning ensures that pouch 72 b is positioned on outstep surface 21 b of shoe 20, and pouch 72 c is positioned on instep surface 21 c of shoe 20.
When the athlete kicks a ball with top surface 21 a of shoe 20, the ball presses against pouch 72 a, causing the instance of circuit 40 inside pouch 72 a to produce a short duration of tactile feedback. Similarly, when the athlete kicks the ball with outstep surface 21 b, the instance of circuit 40 inside pouch 72 b produces a short duration of tactile feedback. Similarly, when the athlete kicks the ball with instep surface 21 c, the instance of circuit 40 inside pouch 72 c produces a short duration of tactile feedback.
In one variation of device 70, each pouch may hold a different circuit. Pouch 72 a may hold a first circuit; pouch 72 b may hold a second circuit, and pouch 72 c may hold a third circuit. Each circuit may be configured to produce a unique pattern of tactile feedback in response to a ball impact. The unique pattern of tactile feedback identifies a specific surface of shoe 20 that made contact with a ball. For example, the first circuit inside pouch 72 a may produce one short pulse of vibration in response to a ball impact; the second circuit inside pouch 72 b may produce two short pulses of vibration, and the third circuit inside pouch 72 c may produce three short pulses of vibration.

Structure of the Fifth Embodiment

FIG. 14 shows a device 80 constructed in accordance with a fifth embodiment of the present disclosure. Device 80 includes a strap assembly 81 for releasably positioning device 80 on shoe 20. Strap assembly 81 includes a stretchable strap 81 a. Similarly to strap assembly 71, strap assembly 81 includes a plurality of pouches. Strap assembly 81 includes a pouch 82 a, a pouch 82 b, and a pouch 82 c.
As shown in FIG. 14, device 80 includes a circuit 84. Circuit 84 includes a circuit board 84 a. Circuit 84 also includes a plurality of tactile switches 85, 86, and 87. Circuit 84 further includes a plurality of electrically conductive wires 83 a, 83 b, 83 c, and 83 d. Tactile switch 85 is mounted on circuit board 84 a. Pouch 82 a holds circuit board 84 a and tactile switch 85; pouch 82 b holds tactile switch 86, and pouch 82 c holds tactile switch 87. Wires 83 a, 83 b, 83 c, and 83 d are located inside strap assembly 81. Wires 83 a and 83 b connect tactile switch 86 to circuit board 84 a. Wires 83 c and 83 d connect tactile switch 87 to circuit board 84 a.
FIG. 15 is a circuit diagram of circuit 84. Circuit 84 is similar to circuit 40. Like circuit 40, circuit 84 includes vibrating motor 43, battery 44, capacitor 45, transistor 46, and resistor 47.
Circuit 84 is also different than circuit 40. In circuit 40, positive terminal 44 a of battery 44 connects to one tactile switch. In circuit 84, positive terminal 44 a of battery 44 connects to three tactile switches, wired in parallel. Specifically, positive terminal 44 a connects to a terminal 85 a of tactile switch 85. Positive terminal 44 a also connects to a terminal 86 a of tactile switch 86 via wire 83 a. Positive terminal 44 a further connects to a terminal 87 a of tactile switch 87 via wire 83 c. A terminal 85 b of tactile switch 85 connects to terminal 47 a of resistor 47 and terminal 45 a of capacitor 45. A terminal 86 b of tactile switch 86 connects to terminal 47 a of resistor 47 and terminal 45 a of capacitor 45 via wire 83 b. A terminal 87 b of tactile switch 87 connects to terminal 47 a of resistor 47 and terminal 45 a of capacitor 45 via wire 83 d.

Operation of the Fifth Embodiment

Similarly to device 70, device 80 may be used to practice straight kicks, outstep pass kicks, and instep pass kicks without repositioning the device. FIG. 14 shows device 80 properly positioned on shoe 20. To properly position device 80, the athlete slides strap assembly 81 over shoe 20, positioning pouch 82 a on top surface 21 a of shoe 20.
When the athlete kicks a ball with top surface 21 a, outstep surface 21 b, or instep surface 21 c of shoe 20, the ball presses against pouch 82 a, 82 b, or 82 c, respectively. The ball pressing against pouch 82 a, 82 b, or 82 c depresses tactile switch 85, 86, or 87, respectively.
The electrical operation of circuit 84 is similar to the electrical operation of circuit 40. In circuit 40, when tactile switch 41 is depressed, electric current flows through the depressed switch, which causes vibrating motor 43 to vibrate for a short duration of time. Similarly, in circuit 84, when tactile switch 85, 86, or 87 is depressed, electric current flows through the depressed switch, which causes vibrating motor 43 to vibrate for a short duration of time.

Structure of the Sixth Embodiment

FIG. 16 shows a device 90 constructed in accordance with a sixth embodiment of the present disclosure. Device 90 includes a strap assembly 91 for releasably positioning device 90 on shoe 20. Strap assembly 91 comprises a pouch 92, a thin stretchable strap 91 a, and a thin stretchable strap 91 b. Pouch 92 holds circuit 40 and connects to strap 91 a and strap 91 b. Strap 91 a wraps around shoe 20 between cleat 24 a and cleat 24 b. Strap 91 b wraps around shoe 20 between cleat 24 b and cleat 24 c. Alternatively, straps 91 a and 91 b may wrap around shoe 20 between other cleats. Additionally, strap assembly 91 may comprise more than two straps.

Operation of the Sixth Embodiment

Device 90 comprises thin straps. An athlete may position thin straps between cleats, as shown in FIG. 16. Positioning straps between cleats allows the athlete to position device 90 on a variety of surfaces of shoe 20. Different surfaces of shoe 20 correspond to different kicking techniques. The athlete may position device 90 on a forward top surface 21 d, a forward outstep surface 21 e, and a forward instep surface 21 f. The athlete may also position device 90 on top surface 21 a, outstep surface 21 b, and instep surface 21 c. These surfaces serve as examples of possible locations for device 90. The athlete may also position device 90 on other surfaces of shoe 20.
In FIG. 16, the athlete has positioned device 90 for practicing a soccer kicking technique called dribbling. To dribble, the athlete moves forward with ball 30 by repeatedly tapping ball 30 using forward top surface 21 d of shoe 20. If the athlete correctly taps the ball using forward top surface 21 d of shoe 20, the ball presses against pouch 92 and momentarily depresses tactile switch 41. Depressing tactile switch 41 causes circuit 40 to produce a short duration of tactile feedback for the athlete. The tactile feedback indicates to the athlete that he or she has tapped the ball with a desirable surface of the shoe for dribbling.

Structure of the Seventh Embodiment

FIGS. 17, 18, and 19 show a device 100 constructed in accordance with a seventh embodiment of the present disclosure. FIG. 17 shows a front perspective view of device 100. As shown in FIG. 17, device 100 includes an assembly 101 for releasably positioning device 100 on shoe 20. Assembly 101 comprises a rigid enclosure 101 a. Enclosure 101 a holds circuit 40 and encloses all components of circuit 40 except a button portion 41 c of tactile switch 41. Button portion 41 c protrudes from the surface of enclosure 101 a. Assembly 101 may be made of plastic, metal, or other rigid materials.
FIG. 18 shows a back perspective view of device 100. As shown in FIG. 18, assembly 101 further comprises a clip 102. Clip 102 is attached to a back of enclosure 101 a.
FIG. 19 shows device 100 operationally mounted on shoe 20. Clip 102 is attached to a shoelace section 22 a of shoelaces 22. Specifically, shoelace section 22 a resides between clip 102 and enclosure 101 a.

Operation of the Seventh Embodiment

To use device 100, an athlete first selects a kicking technique to practice. For example, the athlete may select straight kicks, dribbling, or juggling to practice during a soccer training session. In FIG. 19, the athlete has mounted device 100 to practice straight kicks. The athlete has clipped device 100 to a middle shoelace section 22 a of shoelaces 22. When the athlete kicks a ball using top surface 21 a of shoe 20, the ball depresses button portion 41 c of tactile switch 41, causing circuit 40 to produce a short duration of tactile feedback.
To practice dribbling or juggling, the athlete may clip device 100 to a forward section 22 b of shoelaces 22. When the athlete kicks the ball using forward top surface 21 d of shoe 20, device 100 produces a short duration of tactile feedback.

Structure of the Eighth Embodiment

FIGS. 20, 21, and 22 show a device 110 constructed in accordance with an eighth embodiment of the present disclosure. Like device 100, device 110 includes assembly 101. Unlike device 100, device 110 includes a circuit 111 instead of circuit 40. Enclosure 101 a of assembly 101 holds circuit 111 and encloses all components of circuit 111 except button portion 41 c of tactile switch 41. Button portion 41 c protrudes from the surface of enclosure 101 a.
FIG. 22 shows a circuit diagram of circuit 111. Positive terminal 44 a of battery 44 connects to terminal 41 a of tactile switch 41, a drain terminal 114 a of an N-channel MOSFET transistor 114, and a terminal 113 a of a cylindrical vibrating motor 113. Terminal 41 b of tactile switch 41 connects to a positive terminal 112 a of a microcontroller integrated circuit 112. A source terminal 114 c of transistor 114 also connects to positive terminal 112 a of microcontroller 112. A ground terminal 112 b of microcontroller 112 connects to ground terminal 44 b of battery 44. An output terminal 112 c of microcontroller 112 connects to a gate terminal 114 b of transistor 114, a gate terminal 115 b of an N-channel MOSFET transistor 115, and a terminal 116 a of a resistor 116. A terminal 113 b of vibrating motor 113 connects to a drain terminal 115 a of transistor 115. A source terminal 115 c of transistor 115 connects to ground terminal 44 b of battery 44. A terminal 116 b of resistor 116 connects to ground terminal 44 b of battery 44.
Circuit 111 may comprise different components than the components illustrated in FIG. 22 to produce similar results. For example, motor 113 may be a pancake style vibrating motor like motor 43 in circuit 40. Motor 113 may also be a different type of vibrating motor. Additionally, transistors 114 and 115 may be NPN BJT transistors instead of N-channel MOSFET transistors. Circuit 111 may also be modified to use PNP BJT transistors, P-channel MOSFET transistors, or other types of transistors.

Operation of the Eighth Embodiment

Like device 100, depicted in FIG. 19, device 110 is clipped to a shoelace portion of shoe 20. Device 110 vibrates when the athlete kicks a ball using a surface of shoe 20 located near device 110.
Circuit 111 uses a different set of components than circuit 40 but performs a similar function as circuit 40. Like circuit 40, circuit 111 produces a short duration of tactile feedback when tactile switch 41 is momentarily depressed.
FIG. 22 shows tactile switch 41 in an initially open state. When the switch changes to a closed state, electric current flows into positive terminal 112 a of microcontroller 112. This turns on microcontroller 112. As soon as microcontroller 112 turns on, it produces a high voltage on output terminal 112 c. The high voltage is similar in value to the voltage across ground terminal 44 b and positive terminal 44 a of battery 44. The high voltage appears at gate terminal 114 b of transistor 114, which causes transistor 114 to turn on. When transistor 114 turns on, current flows through transistor 114 from drain terminal 114 a to source terminal 114 c. When current flows through transistor 114, current flows from positive terminal 44 a of battery 44 into positive terminal 112 a of microcontroller 112. Thus, when tactile switch 41 changes back to an open state, microcontroller 112 remains in an on state.
The high voltage microcontroller 112 produces on output terminal 112 c also appears at gate terminal 115 b of transistor 115, which causes transistor 115 to turn on. When transistor 115 turns on, current flows from positive terminal 44 a of battery 44, through motor 113, through drain terminal 115 a and source terminal 115 c of transistor 115, and to ground terminal 44 b of battery 44. When current flows through motor 113, it vibrates.
Microcontroller 112 is programmed to keep output terminal 112 c at high voltage for a short duration of time after it turns on. After the short duration of time elapses, microcontroller 112 produces a low voltage on terminal 112 c. A low voltage on terminal 112 c turns off transistors 114 and 115. When transistor 114 turns off, microcontroller 112 ceases to receive current at positive terminal 112 a, so microcontroller 112 turns off. When transistor 115 turns off, electric current stops passing through motor 113, and motor 113 stops vibrating.
In short, when a ball impact momentarily depresses tactile switch 41, microcontroller 112 turns on. Then, microcontroller 112 outputs a high voltage on terminal 112 c for a short duration of time. The high voltage on terminal 112 c keeps microcontroller 112 in an on state and activates motor 113. After a short duration of time, terminal 112 c drops to a low voltage, turning off microcontroller 112 and deactivating motor 113.
Because circuit 111 performs a similar function as circuit 40, circuit 111 may replace circuit 40 in any of the aforementioned embodiments in which circuit 40 is used. Specifically, circuit 111 may replace circuit 40 in devices 1, 50, 60, 70, 90, and 100.
Many different circuits with different components than circuit 111 may be implemented to produce similar results as circuit 111. For example, instead of using a single microcontroller integrated circuit, a circuit may use multiple integrated circuits such as a 555 timer and a counter to drive a vibrating motor for a short duration after a tactile switch is momentarily depressed.
In another variation of circuit 111, circuit 111 may be designed to use a piezoelectric sensor instead of tactile switch 41. A piezoelectric sensor may produce a signal representative of the magnitude of the force an athlete used to kick a ball. Microcontroller 112 may analyze the signal to determine the magnitude of the force. Microcontroller 112 may then turn on vibrating motor 113 for a duration of time proportional to the magnitude of the force. For example, when an athlete is dribbling, the athlete may strike the ball lightly, and microcontroller 112 may turn on vibrating motor 113 for a short duration of time. When the athlete is striking the ball toward a goal, the athlete may strike the ball with significant force, and microcontroller 112 may turn on vibrating motor 113 for a longer duration of time.
In yet another variation of circuit 111, circuit 111 may receive input from a plurality of sensors positioned on many different surfaces of a shoe. Each sensor may produce a signal routed to microcontroller 112. Microcontroller 112 may then analyze the sensor signals and cause vibrating motor 113 to produce tactile feedback based on an analysis of the signals. For example, microcontroller 112 may determine the first sensor that made contact with a ball, out of a plurality of sensors positioned on a top surface of a shoe. If the first sensor that made contact with the ball is positioned centrally on the top surface of the shoe, microcontroller 112 may cause vibrating motor 113 to produce a longer duration of vibrating feedback, indicating optimal contact with the ball. If the first sensor that made contact with the ball is positioned off-center from the top surface of the shoe, microcontroller 112 may cause vibrating motor 113 to produce a shorter duration of vibrating feedback, indicating suboptimal contact with the ball.
