Introduction

Raymond Nicholson is an accomplished inventor based in Elmhurst, IL (US). He has made significant contributions to the field of coin detection technology, holding 2 patents that showcase his innovative approach to solving practical problems.

Latest Patents

One of his latest inventions is the Coin Detector System. This electronically controlled coin tester positions a sample coin in a magnetic field and passes a test coin through a similar magnetic field to create a null in a detector coil. The output of a square wave oscillator is differentiated to generate a spiked signal for exciting the magnetic field. The presence of the test coin is detected by sensing the quality of the null, and the test coin is accepted based on the duration of the null. A capacitor is charged in the absence of the test coin and discharged in its presence, with acceptance based on the energy stored in the capacitor at the time the null is produced. Additionally, a pendulum damper engages the test coin prior to its entry into the magnetic field, variably retarding it based on coin size.

Another notable invention is the Coin Detector Apparatus. This device distinguishes between valid and invalid coins by subjecting both the test coin and a fixed reference coin to similar magnetic fields. It evaluates the quality of any null signals created by their combined output. The apparatus features a selectively shiftable coin holder that allows for the replacement of the sample coin and provides a guiding ramp for the test coin, which can be set at various inclines depending on the size of the coins being tested. The device may also include a pendulum damper to slow the movement of the test coin and an antistringing device to prevent the removal of a coin from the coin box after acceptance.
