Title: Closed loop tunnel diode receiver for operation with a base band semiconductor transmitter

Abstract: A vehicle safety apparatus includes a base band pulse transmitter-receiver system for the detection of an impending collision immediately prior to the contact of the vehicle with another object for the actuation of restraining or other safety devices to protect the occupants of the vehicle when the crash event actually occurs. A semiconductor base band transmitter and receiver system is synchronously operated by a master clock, providing precise operation of the receiver gain control, sensitivity time control, and other receiver functions, in a low-cost, rugged, long-lived object detection system.
