1. A shock sensor adapted for use in detecting a shock made to a stationary vehicle, said shock sensor comprising:
- a housing which includes a top surface, a bottom surface and side surfaces;
a light source deployed within said housing and adapted to generate light parallel to two of said surfaces;
a light detector deployed within said housing and adapted to receive said generated light; and
an elastic member deployed within said housing and including a first and a second end;
wherein said first end of said elastic member is attached to said bottom surface of said housing, and said second end of said elastic member is attached to a member;
said member is a moveable member which is deployed between said light source and said light detector for blocking said generated light to said light detector, and said member is capable of moving vertically when said shock is made to said stationary vehicle for allowing at least a portion of said generated light to be received by said light detector.

2. A shock sensor adapted for use in detecting a shock made to a stationary vehicle, said shock sensor comprising:
-
a housing which includes a plurality of surfaces; a light source deployed within said housing and adapted to generate light; a light detector deployed within said housing and adapted to receive said generated light; a moveable member deployed within said housing and adapted to block said generated light from reaching said light detector; and an elastic member attached to said moveable member and attached to said housing and which is adapted to elastically move said moveable member in a first plane parallel to a plane containing said light source and parallel to a plane containing said light detector and which is adapted to allow said moveable member to allow at least a portion of said generated light to be received by said light detector in response to said shock made to said stationary vehicle.
