Title: Terrance Gus McDonald: Innovator in Microchip Technology
Introduction
Terrance Gus McDonald is a notable inventor based in Plano, TX (US). He has made significant contributions to the field of microchip technology, holding a total of 5 patents. His work focuses on developing innovative devices that enhance the capabilities of chemical sensing and optical switching.
Latest Patents
One of McDonald's latest patents is the Integrated Microchip Chemical Sensor. This optical device is designed to sense properties in an environment, such as the presence of a substance or chemical. It utilizes optical components integrated on a microchip substrate. A preferred embodiment of this invention introduces a method for fabricating a miniature microchip chemical sensor by integrating a GaAs LED with a polyimide waveguide and a silicon photosensor on the same chip. The device emits light at the edge of the GaAs LED, and when a gas or chemical to which the material is sensitive appears, the light transmitted from the polyimide to air increases, indicating detection.
Another significant invention is the Non-Contacting Micromechanical Optical Switch. This device features a reflective surface with two angled reflective surfaces positioned opposite a micromechanical device. The micromechanical device reflects light input along a path to the first angled reflective surface, which then directs the light to the second surface for output along another path. The position of the reflective member determines the output path, and it always returns to a known position upon loss of power.
