Abstract: A control system includes a controller configured to provide a drive signal, and a switching device configured to generate an output control signal as a function of the drive signal in an on-state mode of operation. The control system also includes a timing network configured to receive the drive signal and output a gated signal to the switching device, wherein the gated signal maintains a relationship with a predetermined threshold during the on-state of operation of the switching device.

Abstract: A method and system for transferring pulse messages between remote-controlled modules in an automotive vehicle includes a single wire bus coupled to each of the modules for transferring the pulse messages between each of the modules. A receiver circuit associated with at least one of the modules and coupled to the bus provides a communication current to the bus. A transmitter circuit associated with at least one of the modules and also coupled to the bus transmits the pulse messages utilizing the communication current. The receiver circuit, thus, becomes active and accepts the pulse messages being transmitted by the transmitter circuit upon detecting the communication current being drawn from the receiver circuit.

Abstract: An automotive electrical system and method for coupling power to such a system in which current cumulatively drawn by the various modules of the system during its inactive state is minimized. In one aspect of the invention, the electrical system (10) comprises at least one remote module (14a-n) coupled to a power bus (21) and a signal bus (16), at least one of the remote modules (14a-n) is coupled to at least one wake-up input switch (28A-I); a central module (12) coupled to the remote module (14a-n) by the signal bus (16), the central module (12) coupling electrical power from a power source (20) to the power bus (21) in response to a detection of an activation of any of the wake-up input switches (28A-I).
