Abstract: This invention is a bus communication protocol. A master device stores bus credits. The master device may transmit a bus transaction only if it holds sufficient number and type of bus credits. Upon transmission, the master device decrements the number of stored bus credits. The bus credits correspond to resources on a slave device for receiving bus transactions. The slave device must receive the bus transaction if accompanied by the proper credits. The slave device services the transaction. The slave device then transmits a credit return. The master device adds the corresponding number and types of credits to the stored amount. The slave device is ready to accept another bus transaction and the master device is re-enabled to initiate the bus transaction. In many types of interactions a bus agent may act as both master and slave depending upon the state of the process.

Abstract: A remote memory preference system for a passenger vehicle is disclosed. The remote memory preference system utilizes existing passive or active remote entry devices. Memory preference settings include driver's seat position, mirror positions and radio station presets. Once these settings are adjusted by a primary vehicle user, they are stored in a memory location in the vehicle either automatically or when a memory button on the remote entry device is depressed by the user. Settings may then be later recalled either automatically by activating the remote entry device or when a recall button on the remote entry device is depressed by the user. The system may also employ a shift register system, which would automatically store current and previous memory preference settings.

Abstract: A keyless entry system includes a RF/LF transmitter (24), a passive signaling device (22), an entry antenna (32), a passive entry module PEM (34), an electronics module (36) and a transponder antenna (38). The transponder antenna (38) communicates directly with the electronics module (36). Should the PEM fail, locating the passive signaling device (22) adjacent the transponder antenna (38) will authorize engine start. Since the transponder antenna (38) does not communicate with the electronics module (36) through the PEM (34), failure of the PEM (34) does not result in a vehicle immobilizing single point failure.

Abstract: An improved bed frame structure that includes initially separate headboard and footboard members, the legs of the headboard and footboard being connected by initially separate side rails. In the preferred embodiment, two tension rods are connected in an X-pattern between the side rails. The tension rods are sized, relative to their connection points with the side rails, so that the rods are maintained under tension, i.e., so that the side rails are slightly bowed inwardly when the frame is erected, thereby locking the headboard footboard and side rails into a tight bed frame configuration.
