Title: Leonard J. Miller and an Invention for Detecting Excessive Current Draw.

Introduction

Leonard J. Miller is an inventor associated with Hartland, Michigan, and TRW Limited. His patent work includes a method and apparatus designed to detect excessive current draw in an electrical load, while accounting for the temporary surge that can occur when the load is first energized.

Latest Patents

Miller is credited with 1 patent: “Method and Apparatus for Detecting Excessive Current Draw in an Electrical Load.” The invention uses a current-sensing circuit to produce a signal that varies with the load’s current draw. A comparator evaluates that signal against a reference, and its output helps control a switch connecting the load to an energy source.

To avoid mistaking ordinary in-rush current for a fault, the system temporarily couples the switch’s control signal to the load-sense signal. This offsets the change caused by startup current, while still allowing the circuit to identify exceptionally high current, such as that associated with a short circuit.

Career Highlights

Miller’s listed patent reflects work on electrical-load protection and current monitoring. The disclosed approach combines sensing, comparison, and switch control to distinguish a normal startup surge from potentially dangerous excessive current.

Collaborations

Miller’s listed coworkers include Daniel G. Brennan and Mark J. Gutwald. The patent information provided does not specify their individual contributions to the invention.

Conclusion

Leonard J. Miller’s patent describes a practical way to improve overcurrent detection by accounting for in-rush current while preserving protection against severe electrical faults.
