Portable electronic devices such as MP3 players, camcorders, digital cameras, PDAs, laptop computers, and cellular telephones are becoming increasingly small and portable. The demand for increased portability and convenience drives a major trend in the consumer electronics marketplace toward wearable electronic devices that can be attached to garments. These “wearable electronic devices” require electrical connection both with other devices (i.e., headphones connected to an MP3 player) as well as with circuits that form part of a garment itself (i.e., conductive fibers, etc.). Wearable electronic devices also require mechanically strong connections because the electronic devices need to stay attached to a wearer's garment as the wearer moves (i.e., a portable MP3 player attached to a jogger's shorts). They also require innovative power cells and switches. Further, wearable electronic devices also demand a level of fashion and functionality (i.e., as garment closures) not generally associated with conventional electronic devices.
Currently, conventional batteries (for example, AA sized 1.5 volt AA alkaline cylindrical batteries with a positive terminal one end and a negative terminal on the other) or batteries designed for specific devices such as NiCd, NiMH, or Li Ion cellular phone batteries re used as power sources portable electronic devices. The term battery is herein defined as any portable power source. Batteries are usually contained in a housing within a portable electronic device. This often adds significantly to the weight of the portable device. Additionally, it can be cumbersome to replace the batteries, especially when the portable electronic device is integrated into a wearable garment. Further, different devices often require different shaped batteries (i.e., a cell phone may require a 6 volt NiMH battery shaped for the specific brand and model number phone, whereas an MP3 player takes standard AA 1.5 volt cylindrical batteries). Given the requisite power demands of these portable devices, it is difficult for a user to always carry replacement power sources, or stop for recharging, while in transit. Further, it is cumbersome to attach or remove prior art batteries for the frequent washing of a garment. Thus, current batteries lack the requisite design, functionality, and user interface required by the fashion/garment industry.

The invention provides many additional advantages that are evident from the description, drawings, and claims.
Battery I also has two moveable portions 6 and 7 that are, for example, pistons. Moveable portions 6 and 7 can be depressed along arrows 8 and 9. When depressed, holes (not shown) in moveable portions 7 and 8 align with apertures 3 and 2, respectively. This allows the position of the battery 1 along the electrical connectors 4, 5 to be altered. Electrical connectors 4, 5 can be formed of, for example, an insulated conductive fabric cord or electrically conductive webbing. Additionally, electrical connectors 4, 5 contain segments 10, 11 corresponding to a negative contact and a positive contact, respectively. Moveable portions 8 and 9 contain a negative terminal and a positive terminal, respectively. When battery 1 is positioned such that segments 10, 11 are with apertures 2 and 3, respectively, a circuit is formed and current passes from battery I through electrical connectors 4 and 5 to power a portable device.
Additionally, The edge in hole 26 either contains negative terminal 25 or supports it. The edge in hole 27 either contains positive terminal 24 or supports it. When pressure is applied to moveable portions 7 and 8, mechanical resistance generator 23 compresses. This may break electrical contact between positive terminal 24 and electrical connector 5. This also may break electrical contact between negative terminal 25 and electrical connector 4. Further, the compression of mechanical resistance generator 23 overcomes the frictional force caused by the edge of holes 26, 27 pressing against electrical connectors 4, 5 and allows battery 1 to alter positions along the length of electrical connectors 4, 5. Additionally, battery 1 can be removed entirely from electrical connectors 4, 5 and placed in a recharging station (not shown).
Fuel cell compartment 21 contains a power source, such as an electrochemical cell of NiCd, or ZnHg. To protect moveable portions 6, 7 and mechanical resistance generator 23 from degradation caused by the power source, each can be compartmentalized within the battery housing 20. Additionally, each can also be coated to protect their contents from degradation.
Additionally, when force is applied to alignment mechanism 63 by mechanical resistance generator 66, this can create an electrical contact between positive terminal 64 and positive first portion 50 of electrical connector 40, and negative terminal 65 and negative second portion 51 of electrical connector 40. A reduction in the force generated by mechanical resistance generator 66 may break electrical contact between positive terminal 64 and positive first portion 50 of electrical connector 40, and negative terminal 65 and negative second portion 51 of electrical connector 40. Further, a reduction in the force generated by mechanical resistance generator 66 allows battery 43 to alter its positions along the length of electrical connector 40. Additionally, battery 43 can be removed entirely from electrical connector 40 and placed in a recharging station (not shown).
Fuel cell compartment 67 contains a power source, such as an electrochemical cell of NiCd, or ZnHg. To protect moveable portions 41, mechanical resistance generator 66, alignment mechanism 63, and electrical connector 40 from degradation caused by the power source, each can be compartmentalized within the battery housing 68. Additionally, each can also be coated to protect their contents from degradation.
Fuel cell compartment 94 contains a power source, such as an electrochemical cell of NiCd, or ZnHg. To protect wheel 91, and its mechanical resistance generator from degradation caused by the power source, each can be compartmentalized within the battery housing 20. Additionally, each can also be coated to protect their contents from degradation.
Electrical connectors can have multiple circuit portions as shown in
Battery 1 can be removed from garment 110 by depressing the moveable portions and sliding battery 1 off of electrical connectors 4, 5. Additionally, battery I can be used to power any type of electrical device.
