Title: Innovations by Kevin L Nelson

Introduction

Kevin L Nelson is an accomplished inventor based in Virginia Beach, VA (US). He has made significant contributions to the field of electrical engineering, particularly in the development of automatic switched power receptacles. With a total of three patents to his name, Nelson's work showcases his innovative approach to enhancing electrical systems.

Latest Patents

One of Nelson's latest patents is focused on hysteresis in a circuit for sensing the presence of a plug. This invention includes an outlet receptacle designed to receive a plug, with a relay that selectively powers the receptacle. A plug presence sensor, which consists of a light source and a light sensor, detects the presence of a plug being inserted. The automatic control circuit energizes the relay to power the receptacle when a plug is sensed.

Another notable patent is a circuit for overriding the cripple mode, ensuring that the relay remains latched. This invention utilizes a plug presence sensor with an LED and a light sensor in the form of a photo-transistor. The microcontroller monitors the sensor to control the relay's latching. In the event of a communication loss with a remote master controller, the microcontroller de-energizes the relay to cut power to the receptacle. However, the override circuit simulates the removal and reinsertion of the plug, keeping the relay energized.
