Abstract: The present invention advantageously provides a microprocessor controlled power delivery circuit with short circuit protection. The microprocessor controls the load current flow at the circuit's load connection terminal by connecting this terminal to the positive or negative side of a power supply or opening the circuit to prevent current flow. The short circuit protection uses a passive electrical component feedback circuit to communicate the voltage level at the circuit's load connection terminal back to the microprocessor. The microprocessor routinely monitors this voltage and compares this voltage against the expected voltage at this terminal. When the actual voltage does not match the expected voltage, the circuit will provide protection by interrupting current flow through the load connection terminal.

Abstract: A control system for an automotive vehicle multi-functional apparatus employs an electronic control unit operably controlling a rear window wiper assembly. In another aspect of the present invention, an electronic control unit is operable as a multiplexed rear node for controlling a variety of liftgate devices and functions. In a further aspect of the present invention, an electronic control unit controls a single multi-functional electromagnetic device. The multi-functional electromagnetic device uses intermittent motion mechanisms to selectively operate differing devices driven therefrom. A method of operating the electronic control unit of the present invention is also provided.

Abstract: A linkage has a coupled state, where actuation of a multi-functional apparatus causes an interference device to move between the locked position and the unlocked position, wherein in the locked position the interference device does not allow a handle for opening door latches to actuate, and in the unlocked position the interference device allows the handle to actuate. The linkage further has a decoupled state, where actuation of the manual actuation device causes the decoupling linkage to uncouple from the multi-functional apparatus, and causes the interference device to move between the locked and the unlocked positions without moving the multi-functional apparatus. This arrangement allows for a manual override of the power liftgate lock multi-functional apparatus.
