Patent ID: 8100000

Claim:
A portable device for detecting defective teeth of a vehicle engine pulse generator plate, comprising: a pair of detection sensors for temporary association with a vehicle engine of interest, said detection sensors adapted to detect the teeth of a pulse generator plate of said vehicle engine from a location external to said engine; a controller in communication with said pair of detection sensors, said controller including at least a microprocessor device and an associated program; and an indicator in communication with said controller, said indicator activatable by said controller to inform a user of a damaged or undamaged pulse generator plate condition; wherein said pair of detection sensors are arranged such that one sensor leads the other with respect to detecting the teeth of said pulse generator plate during rotation thereof; and wherein output signals generated by each detection sensor upon tooth detection produce a corresponding pulse train, said pulse trains evaluated by said program and said microprocessor device to detect any bent and/or unintentionally missing teeth on said pulse generator plate.
