Abstract
A motor drive system for imparting oscillating motion to a window wiper is disclosed which slows the wiper as it approaches respective right and left positions and holds the wiper at the right and left positions for a selectable delay interval in order to avoid deleterious effects of instantaneous motor direction reversal. The system includes a motor drive chip for generating the drive signal to the window wiper motor, a programmable logic array for sequencing the operation of the motor drive chip, and a delay chip for timing the selected delay.
