Abstract: In a flat flex cable, signal lines are surrounded by logic ground planes above and below which are viaed together left and right. The ground planes coupled with the flex cable dielectric determine characteristic the impedance and attenuation of the cable and provide differential signal EMI shielding. All signal layers and logic ground planes are enclosed within the two outermost shield layers which are viaed together left and right and around the connectors to enclose both signal layers and logic ground planes to provide common mode EMI shielding.

Abstract: A key fob for housing at least one electrical component for wireless communication with a vehicular system includes a main body having at least one actuator button. The actuator button is operable to control an electrical component for wireless communication with a vehicular system. The main body includes a first detent mechanism. The key fob further includes a cap moveably connected to the main body. The cap is moveable between a closed position and an open position such that in the closed position the cap at least partially covers the actuator button and such that in the open position the cap at least partially exposes the actuator button. The cap includes a second detent mechanism. The second detent mechanism is operable to cooperate with the first detent mechanism to lock the cap relative to the main body in one of the closed position and the open position.

Abstract: A method and apparatus are provided for implementing characteristic impedance discontinuity reduction in customized high-speed flexible circuit applications. A curved artwork region is selected and selected cells are scanned. An area on opposite sides of a signal wire within each cell is determined. The identified areas are compared using a user defined delta value. If the compared areas differ greater than the user defined delta value, then a coordinate change is computed for moving the signal wire to reduce characteristic impedance discontinuity.

Abstract: A method, structure and computer program product are provided for implementing high frequency return current paths within electronic packages. Electronic package physical design data is received for identifying a design layout. For each of a plurality of cells in a grid of a set cell size within the identified design layout, a respective number of signal vias, reference voltage vias, and ground vias are identified. A signal to reference via ratio is calculated for each of the plurality of cells. Each cell having a calculated signal to reference via ratio greater than a target ratio is identified. Vias are selectively added within each of the identified cells for providing high frequency return current paths.

Abstract: Embodiments of the present invention provide a method and system for multi-link data communications using a multi-threaded and/or multi-processor system. An embodiment of the present invention includes a receive interface to couple to a multi-link communications channel. A processing system processes header portions of data fragments received from the multi-link communications channel. A separate processing system processes payload portions of the data fragments from the multi-link communications channel. The payload processing system includes a memory that is slower than a memory of the header processing system.

Abstract: Dynamically distributing portions of process functionality among plural functional blocks. A plurality of service point functions are interspersed throughout each function block. Each service point function performs a portion of processing. A service point function may correspond to processing associated with a protocol layer. A service point function may be implemented in hardware, software or firmware with any of the multiple function blocks. After completion of each service point function, a sub-path is called to connect the completed service point function with a next service point function to be performed. The sub-path invokes a pointer which provides the next routine (e.g., the service point functionality) to be performed. If any one functional block is becoming overloaded, the system can simply change one sub-path, to route process functionality associated with a particular service point functionality to be performed in another functional block with the same capability programmed or hardwired therein.
