Automatic Device Counting System

This tool will count, count/verify chips for receipts, rotating inventory control audits and adjust chip counts under processor control at a high rate of speed and accuracy.

A tungsten halogen generated light 10 is sent through four fiber-optic cables 12 and then optically concentrated at the distal end to emit four intense light beams. These beams are permanently displayed on four photodetector devices 14, creating an electrical continuity. Anything breaking these light beams creates a signal in the photodetector. Semiconductor device banks with apertures 16 aligned with the beams are moved past the beams so that devices in the apertures break the light beams to generate count signals. In some applications, a laser may be used in place of the tungsten-halogen source 10.
