Shoe with sensors, controller and active-response elements and method for use thereof
View Patent ↗Active-response golf shoes are disclosed. The golf shoes include at least one sensor, a controller, and at least one active-response element. The sensor and controller operate to rapidly determine if a golfer is walking or swinging a golf club. Once this determination is made the controller and active-response element rapidly change the shoe's characteristics. If the controller determines that the golfer is walking, the shoe provides a soft and flexible walking platform. If the controller determines that the golfer is swinging, the shoe morphs or changes automatically to provide a stable hitting platform. The controller senses various predetermined conditions such as pressure under the ball of the user's foot to determine whether the golfer is walking or swinging. The active-response elements may be a sole adjuster, a lace adjuster, and/or an upper adjuster. Methods of determining the golfer's type of movement are also disclosed.
1. A shoe comprising:
an upper, at least one active-response element, a sole coupled to the upper to define a chamber for receiving a wearer's foot, at least one sensor, and a controller operatively connected to said sensor and said active-response element,
wherein said controller determines whether the wearer is walking or swinging and when the wearer is swinging, said controller sends an output current to said active-response element and said active-response element changes said shoe from an initial state where the shoe exhibits a first set of characteristics to a transitory state where the shoe exhibits a second set of characteristics different from said first set of characteristics.
2. The shoe of claim 1 , wherein said output current is sent to said sensor, and said sensor sends said output current to said active-response element.
3. The shoe of claim 1 , wherein said active-response element comprises a sole adjuster, an upper adjuster, a tongue adjuster or a lace adjuster.
4. The shoe of claim 1 , wherein said controller sends said output current if said sensor senses a pressure greater than a preset swing threshold within a preset time interval threshold.
5. The shoe of claim 1 , wherein said sensor is a pressure sensor that underlies the ball of the wearer's foot.
6. The shoe of claim 5 , wherein the pressure sensor underlies the wearer's foot's fifth metatarsal head.
7. The shoe of claim 4 , wherein the swing threshold is between about 70 kPa to about 140 kPa.
8. The shoe of claim 7 , wherein the swing threshold is about 100 kPa.
9. The shoe of claim 4 , wherein the time interval threshold is about 0.5 second.
10. The shoe of claim 7 , wherein the time interval threshold is about 0.5 second.
11. The shoe of claim 1 , wherein the first set of characteristics is indicative of walking.
12. The shoe of claim 11 , wherein the second set of characteristics is indicative of swinging.
13. The shoe of claim 12 , wherein during walking said sensor generates energy that is harvested.
14. The shoe of claim 12 , wherein during swinging the controller converts the harvested energy to said output current.
15. The shoe of claim 1 , wherein the shoe is more stable when exhibiting the second set of characteristics than the first set of characteristics.
16. The shoe of claim 15 , when exhibiting the second set of characteristics the wearer's foot is less movable relative to the shoe.
17. The shoe of claim 1 , wherein the sole comprises at least two sensors, wherein the two sensors are located proximately under any two metatarsal heads.
18. The shoe of claim 17 , wherein the two sensors are spaced apart.
19. The shoe of claim 17 , wherein one sensor is located under the fourth metatarsal bone and another sensor is located under the fifth metatarsal bone.
20. The shoe of claim 17 , wherein when the wearer is walking the at least two sensors sense pressure peaks at about the same time.
21. The shoe of claim 17 , wherein when the wearer is swinging the at least two sensors sense pressure peaks sequentially.
22. The shoe of claim 1 , wherein the at least one sensor is made of piezoelectric material.
23. The shoe of claim 1 , wherein the at least one sensor is made of an insulating polymer.
24. The shoe of claim 23 , wherein the at least one sensor is made of a silicone or an acrylic elastomer.
25. The shoe of claim 23 , wherein the at least one sensor is made of polyurethane, fluorosilicone, fluoro-elastomer, polybutadiene or isoprene.
26. The shoe of claim 3 , wherein the sole adjuster is positioned diagonally relative to the sole.
27. The shoe of claim 3 , wherein the sole adjuster comprises two adjusters positioned diagonally relative to the sole and diagonally opposite from each other.
28. A shoe comprising an upper and a sole coupled to the upper to define a chamber for receiving a wearer's foot, wherein said shoe distinguishes whether the wearer is walking or swinging.
