Controller for plural area sensors
First Claim
1. A controller for use with a plurality of area sensors, said controller controlling more than one area sensors each of said more than one area sensors having a light projector and a light receiver each, said light projector and light receiver being connected by a plurality of optical paths, said controller comprising:
- a master controller, for controlling said more than one area sensors; and
a slave controller connected to said master controller, for perfonning signal transfer between said master controller and said at least one of said more than one area sensors.
