Patent Images
1. An electronic device comprising:
- an accessible surface with a recess;
a security bezel having a light pipe, said security bezel being removably seated in said recess;
a light source;
a light detector, wherein said light source and said light detector are spaced apart within said recess, so that when said security bezel is removed from said recess there is no optical path between said light source and said light detector, and when said security bezel is seated in said recess said security bezel provides an optical path through said light pipe between said light source and said light detector; and
circuitry for at least partially disabling said electronic device when light from said light source does not reach said light detector.

Abstract
The invention is a theft deterrent arrangement for a motor vehicle audio apparatus (10) wherein the audio apparatus (10) is enabled when an optoelectronic circuit (7,11,13) is closed by a security bezel (1) removably seated in a recess (3) in a front face (2) of the audio apparatus (10). The security bezel (1) has a light pipe (17), so that when the security bezel (1) is seated in the recess (3), the light pipe (17) provides an optical path (32) between a light detector (13) and an emitter (11) fixedly mounted in the recess (3), thereby closing the optoelectronic circuit (7,11,13) and enabling the audio apparatus (10).
