Title: Method and apparatus for the automated pad structure that is optimized for saving leakage current in a modem of user equipment
Inventor: PARK NAM JOO
IPC: G06F1/00
Filed: 2006-02-02
Abstract: A method and a device for automatically setting a pad schematic optimized to prevent a leakage current in a modem of a user terminal is provided to reduce a sleep current with minimized power consumption in a sleep mode of the user terminal by simplifying the pad schematics inside the modem, controlling all pads, and simply setting software. When the user terminal starts the sleep mode, a normal output pad is opened and the program data pad controls the selected pad with program data if a setting value of a program selection bit is written to 0 from 1. When the sleep mode is finished, a two 2 or 3-state pad is restored to a normal output state if the program selection bit is written to 1. If a user wants to set a high state to the predetermined pad in the sleep mode, a non-3-state output pad defines 1 to a pad program data bit and writes 0 to the program selection value when being entered into the sleep mode. If the setting value is set by 1 but the program selection value is set by 0, the non-3-state output pad performs pad setting with hardware by automatically using an idle or sleep mode signal as the program selection signal.

Title: Electrical connector assembly
Inventor: SENK JOSEPH M
IPC: H01R13/629
Filed: 2006-03-23
Abstract: The present invention provides an electrical connector assembly and a method of mating the same. The electrical connector assembly includes a panel sub-assembly (22) which mates to at least one electrical connector body (32). Preferably two cam leveraging devices (38,40) which rotate in opposing directions are mounted rotatably to the panel sub-assembly (22) for sliding engagement of respective cam studs (84,86,88,90) engaged rigidly to the electrical connector body (32). Opposing rotations of the cam leveraging devices (38,40) along respective and parallel rotation axes (42,44) causes the panel sub-assembly (22) to move linearly along a mating axis (36) disposed orthogonally to the rotation axes (42,44) and toward the electrical connector body (32) to a staged position. During linear panel sub-assembly movement from the disconnected position to the staged position, the cam studs (84,86,88,90) slide against a first portion (104) of a track (82) carried by respective cam levers (38,40) and which generally spirals radially inward toward the rotation axis. Reversing rotation of both cam leveraging devices (38,40) causes the panel sub-assembly (22) to continue linear movement toward the electrical connector body (32) from the staged position and to a mated position. During linear panel sub-assembly movement from the staged position to the mated position, the cam stud (84,86,88,90) lifts off of the first portion, and is caught by and slides along a second portion (118) of the track to a mated end (122).
