Title: Alan J Kumasaka: Innovator in Sensor Technology

Introduction

Alan J Kumasaka is a notable inventor based in Hackettstown, NJ (US). He has made significant contributions to the field of sensor technology, particularly with his innovative fail-safe sensor system. His work has implications for various applications where reliable sensor operation is critical.

Latest Patents

Kumasaka holds a patent for a fail-safe sensor system. This system provides a positive indication of the proper operation of a sensor by accounting for return signals from both an active zone and a monitor zone. The design allows search signals from a transducer to be transmitted within an active zone, where objects are expected to be detected. If search signals are not returned, they can travel into a monitor zone, where objects can also cause return signals. A counter fed by a free-running clock source tracks the operation time of the sensor system. If no return signal is detected, the counter can exceed its limit, triggering an output signal to control circuitry or an alarm.
