Abstract: A portable (travel) charger or power adaptor (10) can minimize the protrusion from a wall when used as a wall mounted charger and can further maximize the number of power adaptors that can be (safely) plugged into a standard AC strip. The power adaptor can include a housing (12) containing a power transformer and a pair of pivoting prongs (13 and 15) forming a plug (14) arranged to be substantially near a top portion of the housing. The pair of pivoting prongs in a first position or horizontal position can make the adaptor suitable or configured for coupling to an AC wall outlet receptacle and in a second position or vertical position can make the adaptor suitable or configured for placement in an AC strip receptacle (22) of a standard power strip (20).

Abstract: A system (100) includes a wireless device (101) and at least one transponder (102). The wireless device (101) includes a memory (201) with an area (202) for storing coupling range profiles, a processor (203), a bus (210), a receiver (206), a transmitter (205), an alarm (208), a location module (209), a user interface (211), an antenna (212) for receiving transmitted location information, a power controller (204), an antenna (207) for transmitting and receiving, and a clock (213). The transponder includes a memory (301) with an area (302) for storing a unique transponder ID, a processor (303), a bus (308), power controller (304), a receiver (306), transmitter (305), and an antenna (307). The wireless device (101) compares current context information to a coupling range profile and, based on the results of the comparison, transmits to at least one transponder (102) at an appropriate power level.

Abstract: A method and apparatus form electrical connections between electronic circuits and conductive threads (102, 104, 106, 108) that are interwoven into textile material (130). Electronic circuits (128), such as semiconductor dies, are connected to a carrier (132) and electrical connections (136) are made to conductive connection areas (110, 112, 114, 116) on the carrier (132). Conductive stitching (202, 204, 206, 208) provides electrical contacts for both the conductive connection areas (110, 112, 114, 116) on the carrier (132) and the conductive threads (102, 104, 106, 108) that are interwoven into the textile material (130). Optionally, a thin, flexible substrate material (132) is perforated during the stitching process.

Abstract: A keyboard (102) includes fist (112) and second (110) hinges that allow the keyboard (102) to be properly placed and fitted against an electronic device such as a cellular telephone (106). The first hinge (112) allows the keyboard 102 to be swung up and away from the cellular telephone's housing and also allows the keyboard (102) to be properly fit against the cellular telephone's housing when in use. This proper fit provides for improved stress relief away from connector (108) when the keys (104) are activated. The second hinge (110) makes it easy for the keyboard (102) to be attached to cellular telephone (106) using connector (108). The dovetail design (308) of the underneath of the keyboard provides amble clearance (302) for the cellular telephone's keys (304).
