Title: The Innovative Contributions of Donald O Parker

Introduction

Donald O Parker is a notable inventor based in Grand Rapids, MI (US). He has made significant contributions to the field of electronic coin analysis, holding a total of 9 patents. His work has paved the way for advancements in coin detection and processing technologies.

Latest Patents

One of Parker's latest inventions is the Low Profile Coin Analyzer Apparatus. This electronic coin analyzer features a low profile design that is particularly useful for applications that were previously limited to mechanical devices. The apparatus includes a test coin path aligned with a coin-receiving opening in a faceplate, along with a rejected coin path that is laterally offset from the test coin path. An electromagnetic actuator selectively positions a coin deflecting surface in the test coin path, allowing for the lateral deflection of coins toward the rejected coin path. Coins that are not deflected continue rolling to an accepted coin path due to inertia. The system is equipped with an electronic control that includes a test coin sensor, which activates the actuator to withdraw the deflecting surface when an acceptable coin is detected.

Another significant patent is the Coin Analyzer Sensor Configuration and System. This system features a coin detecting sensor with a magnetic core that defines an air gap large enough to accommodate any size coin. A coil generates a uniform magnetic flux through the air gap, ensuring that the positioning of the coin is not critical. The design includes a return path in the core to complete the magnetic circuit, and various detection circuits are disclosed for determining the denomination of the test coin.
