Abstract

The invention disclosed herein is directed to a device for converting kinetic energy generated by a living organism in motion to electrical energy.

Claims (26)

1. A device for converting kinetic energy generated by an expandable/contractable element of a living organism to electrical energy, comprising:

a support member;

a first gear operatively coupled to the support member such that the first gear and the support member rotate together in a first direction about an axis;

an electrical generator operatively coupled to the first gear;

an actuator member;

a second gear engaged with the first gear, the second gear coupled to the actuator member such that the actuator member and the second gear rotate together in a second direction about the axis, the second direction being opposite the first direction;

a spring operatively coupled to the actuator member and to the support member;

a flexible non-elastic strap having a proximal end and a distal end, the proximal end being operatively coupled to the actuator member and the distal end being operatively coupled to the support member;

wherein the actuator member is rigid.

2. The device of claim 1 , further comprising a protective case.

3. The device of claim 1 , comprising one or more power outlet ports.

4. The device of claim 3 , wherein one or more of the power outlet ports comprises(s) USB ports.

5. The device of claim 1 , wherein the flexible non-elastic strap fits snugly around the expandable/contractable element of the living organism when in the contracted state.

6. The device of claim 5 , wherein the living organism comprises a mammal.

7. The device of claim 6 , wherein the mammal is a human being.

8. The device of claim 7 , wherein the expandable/contractable portion of the human being is the chest.

9. The device of claim 8 , wherein a resistance of about 1 lb. to about 10 lbs. is generated at the chest at full expansion of the device due to subject inspiration.

10. The device of claim 1 , wherein the electrical generator is electrically coupled to an onboard capacitor.

11. The device of claim 1 , wherein the electrical generator is electrically coupled to an onboard battery.

12. The device of claim 1 , wherein the device comprises two or more individual devices coupled together either in parallel or in series.

13. The device of claim 1 , wherein the device comprises two or more electrical generators, each electrical generator paired with one of two or more first gears to which the generator is operatively coupled, and each of the first gears is operatively coupled to the support member, such that the first gears and the support member rotate together in the first direction about the axis, and each of the two or more first gears are engaged with the second gear.

14. The device of claim 1 , wherein the first gear is a bevel gear, and the second gear is a flat gear comprising gear teeth arranged on a plane.

15. The device of claim 14 , wherein the device comprises a step-up gear assembly comprising the bevel gear and the flat gear.

16. The device of claim 1 , further comprising an axle, wherein the first gear and the support member rotate together in the first direction around the axle, and the actuator member and the second gear rotate together in the second direction around the axle.

17. The device of claim 1 , wherein the spring is operatively coupled to an actuator member operative coupling device and a support member operative coupling device; and the support member is coupled to the proximal end of the flexible non-elastic strap by the support member operative coupling device and the actuator member is operatively coupled to the distal end of the flexible non-elastic strap by the actuator member operative coupling device.

18. The device of claim 17 , where the support member operative coupling device, the actuator member operative coupling device, or both, are coupled to the flexible non-elastic strap by an adjustable closure.
