<p>A position determining system for determining and storing the position of an adjustable element, such as a seat, mirror or steering column in a vehicle. A series of irregularly spaced reference marks or holes is provided. Sensor means 60 are provided for sensing the marks or holes as they are crossed during movement of the adjustable element. The sensor provides signals to a microcontroller which determines the distance between the reference marks or holes crossed during movement of the adjustable element, thereby determining the position of the adjustable element. The position can be stored and retrieved for future use. <IMAGE></p> |
