ABSTRACT:
A power memory seat and mirror apparatus useful for controlling manual and automatic operations is disclosed. Supply voltage switch signals and analog voltage potentiometer sense signals are buffered so as to provide digital logic signals utilized by a microcomputer to store in a non-volatile memory desired seat and mirror position data. Means are provided permitting later recalling of the desired position data and automatically repositioning the seat and mirrors to the memorized positions. The system also provides diagnostic and failure mode operations. Additional means is included for activating the system when the ignition switch of the vehicle is off.
