Title: Innovations of David W Stevenson
Introduction
David W Stevenson is a notable inventor based in Mesa, AZ (US). He has made significant contributions to the field of optoelectronics, holding a total of 5 patents. His work primarily focuses on improving the efficiency and functionality of electro-optic devices.
Latest Patents
One of his latest patents is for a "Single package electro-optic transmitter-receiver." This invention enhances the design of electro-optic transmitter-receivers by arranging a variable light source, such as an LED, and a photosensitive device, like a phototransistor, on a flat leadframe. Both components face outwardly in the same direction, which is approximately perpendicular to the plane of the package leads. A unitary transparent cover protects these components, and a lens is positioned over the phototransistor, ensuring optimal performance. Additionally, a recess is designed into the cover to minimize the transmission of back-scattered light between the LED and the phototransistor.
Another significant patent is the "Hot alignment assembly method for optoelectronic packages." This method provides a cost-effective solution for assembling semiconductive optoelectronic devices by utilizing hot alignment techniques. During this process, electrical power is applied to the semiconductor, facilitating an optical alignment operation that enhances the overall assembly efficiency.
