Title: Gerald Smith - Innovator in Coin Validation Technology

Introduction

Gerald Smith is a notable inventor based in Clayton, NJ (US). He has made significant contributions to the field of coin validation technology. His innovative approach has led to the development of a unique patent that enhances the reliability of coin-operated machines.

Latest Patents

Gerald Smith holds a patent for a "Coin Validating Apparatus and Method." This invention involves a coin validating system that is typically used in coin-operated machines. The system electrically couples a stationary coin to the tuning coils of an oscillator circuit. While the coin remains stationary and the oscillator is tuned to a first rest frequency, the output frequency and output amplitude of the oscillator are measured. The metal coin alters the signal frequency from its rest frequency and decreases the signal amplitude from its rest amplitude. Frequency and amplitude are measured and compared with expected parameters of a valid coin. If a match is made, the rest frequency of the oscillator circuit is adjusted. At the second test frequency, signal frequency and amplitude are again measured and compared with expected parameters for a valid coin. Only if a match is confirmed at both frequencies is an accept gate actuated.
