Title: Innovations by Jeffrey T. Kelley

Introduction

Jeffrey T. Kelley is an accomplished inventor based in Plymouth, MI (US). He has made significant contributions to the field of technology, holding a total of 3 patents. His work focuses on enhancing electronic systems and security measures, showcasing his innovative spirit and technical expertise.

Latest Patents

One of Kelley’s latest patents is a pulse width modulation and protection circuit. This circuit includes a transistor pass element that is alternately switched on and off by an oscillator, connecting a power source to a load. The current through the transistor pass element is compared to a reference signal by a comparator. If the current exceeds the reference signal, the comparator generates a fault signal, switching off the transistor pass element for the remainder of the cycle. After a predetermined number of faults, the transistor is switched off for multiple cycles. This design prevents damage to the transistor pass element and allows for downsizing, ultimately saving product costs.

Another notable patent is an optical anti-theft system. This system incorporates a member with a plurality of reflective surfaces that form a pattern corresponding to a security code. It includes a base that receives the member, which has a light source to generate a beam illuminating the reflective surfaces. A light detector senses the illuminated surfaces and initiates a security function in response to the detected pattern. This innovative approach enhances security measures in various applications.
