Abstract

A system may include a flexible leaf having a fastener, the fastener being electrically conductive, the flexible leaf having a solar cell incorporated therein, the solar cell electrically coupled to the fastener. The system may further include an article of clothing including a respective fastener, the respective fastener being electrically conductive, the flexible leaf configured to couple to the article of clothing via at least the fastener and the respective fastener. The system may also include an electrical circuit incorporated in the article of clothing, the electrical circuit electrically coupled to the respective fastener.

First claim

What is claimed is:

1 . A system comprising:
a flexible leaf having a fastener, the fastener being electrically conductive, the flexible leaf having a solar cell incorporated therein, the solar cell electrically coupled to the fastener; an article of clothing including a respective fastener, the respective fastener being electrically conductive, the flexible leaf configured to couple to the article of clothing via at least the fastener and the respective fastener; and an electrical circuit incorporated in the article of clothing, the electrical circuit electrically coupled to the respective fastener.

2 . The system of claim 1 , wherein the fastener is a snap fastener having a first shape, and wherein the respective fastener is a complementary snap fastener having a second shape, the first shape configured to interlock with the second shape.

3 . The system of claim 1 , further comprising:
a second fastener incorporated in the flexible leaf, the second fastener being electrically conductive; and a respective second fastener incorporated in the article of clothing, the respective second fastener being electrically conductive, wherein the solar cell and the electrical circuit are configured to form at least a portion of a closed circuit loop in response to the fastener being fastened to the respective fastener and the second fastener being fastened to the respective second fastener.

4 . The system of claim 1 , wherein the article of clothing is a portion of a space suit.

5 . The system of claim 1 , wherein the electrical circuit includes at least a battery configured to be charged at least partially by the solar cell.

6 . The system of claim 5 , wherein the battery is configured to power a propulsion system, an environmental control system, a communication system, or any combinations thereof.

7 . The system of claim 1 , wherein the solar cell is a multi junction Gallium-Arsenide solar cell.

8 . The system of claim 1 , wherein the flexible leaf includes a fabric pocket.

9 . The system of claim 1 , wherein the flexible leaf includes a transparent shield.

10 . The system of claim 9 wherein the transparent shield is attached to the flexible leaf with thread, the flexible leaf omitting any polymer adhesive.

11 . The system of claim 9 , wherein the transparent shield is attached to the flexible leave with adhesive.

12 . The system of claim 1 , wherein the article of clothing includes a leg portion, a chest portion, a back portion, an arm portion, or any combination thereof, wherein the respective fastener is positioned on the leg portion, on the chest portion, on the back portion, or on the arm portion.

13 . A system comprising:
a plurality of flexible leaves, each flexible leaf having a pair of conductive fasteners incorporated therein; a plurality of solar cells, each of the flexible leaves having at least one of the solar cells incorporated therein; and an article of clothing including multiple pairs of conductive fasteners incorporated therein, wherein the plurality of flexible leaves are configured to interchangeably connect to each pair of fasteners.

14 . The system of claim 12 , wherein the multiple pairs of conductive fasteners are electrically coupled to an electrical circuit in series with each other.

15 . The system of claim 12 , wherein the multiple pairs of fasteners are electrically coupled to an electrical circuit in parallel with each other.

16 . A method comprising:
generating electrical power at a solar cell incorporated within a flexible leaf having a pair of conductive fasteners; and transmitting the electrical power to a circuit incorporated within an article of clothing via the pair of conductive fasteners and via a pair of respective conductive fasteners incorporated in the article of clothing.

17 . The method of claim 15 , further comprising, before generating the electrical power:
coupling a first conductive fastener of the pair of conductive fasteners with a first respective conductive fastener of the pair of respective conductive fasteners; and coupling a second conductive fastener of the pair of conductive fasteners with a second respective conductive fastener of the pair of respective conductive fasteners.

18 . The method of claim 15 , further comprising:
uncoupling a first conductive fastener of the pair of conductive fasteners from a first respective conductive fastener of the pair of respective conductive fasteners; and uncoupling a second conductive fastener of the pair of conductive fasteners from a second respective conductive fastener of the pair of respective conductive fasteners.

19 . The method of claim 15 , further comprising:
uncoupling the flexible leaf from the article of clothing and coupling a second flexible leaf to the article of clothing, the second flexible leaf having a second pair of conductive fasteners.

20 . The method of claim 15 , further comprising:
charging a battery via the circuit incorporated within the article of clothing.
