Title: The Innovations of Donald E. Schrader

Introduction

Donald E. Schrader is a notable inventor based in Culver City, California. He is recognized for his contributions to optical detection technology, particularly in the field of scanning systems. His innovative approach has led to the development of a unique apparatus that enhances the ability to search large fields of view for modulated optical signal sources.

Latest Patents

Schrader holds a patent for a "Scanning system with a Geneva wheel." This invention is designed to search a large field of view to detect a modulated optical signal source. The apparatus utilizes an optical detector with a field of view capability that is less than the total field of view being searched. A constant drive motor is coupled to a Geneva five-slot single pin mechanism, which is fixed to a drum that is rotatably mounted to a housing. The detector and associated focusing optics are positioned at the bottom of the housing, with a housing window located on one side. Five reflective surfaces are arranged around the circumference of the drum, allowing the Geneva mechanism to intermittently rotate the drum. This sequential positioning reflects optical energy passing through the housing window to the detector apparatus. The reflective surfaces are angled differently around the drum, enabling the system to interrogate various segments of the total field of view.
