1. A collision detecting system comprising:
- (a) a collision sensor secured to a body for generating an AC signal upon occurrence of a collision of the body;
(b) oscillator means connected to the collision sensor and controlled by the AC signal to generate a signal having a frequency higher than that of the AC signal during a portion of each period of said AC signal, said high frequency signal being modulated by the AC signal;
(c) interconnecting means including;
a primary winding connected to said collision sensor and said oscillator means whereby the modulated signal generates an electromagnetic induction field;
a secondary winding operatively related to said primary winding for generating an induced signal in response to the induction field;
first supporting means for supporting said primary winding;
second supporting means for supporting said secondary winding, said second supporting means being detachably joined with said first supporting means whereby when said first and second supporting means are joined, said primary and secondary windings are inductively coupled as a separable contactless connector between the collision sensor and the signal processing circuit; and
(d) a signal processing circuit connected to said secondary winding and responsive to said induced signal for detecting the occurrence of the collision to generate an output signal.

Abstract
A collision detecting system having a collision sensor for generating an AC collision signal and a signal processing circuit responsive to the AC signal for discriminating the occurrence of a collision and for generating an output signal when a collision occurs. A contactless connector interconnects the collision sensor and the signal processing circuit. The connector comprises a pair of separably interconnected elements for respectively supporting a primary winding and a secondary winding in operative relationship to one another, the primary winding being joined to the collision sensor and the secondary winding being connected to the signal processing circuit.
