Latest Patents

Fletcher's latest inventions include the innovative "Liquid Crystal Fiber Optics Large Screen Display Panel" and the "Pulsed Ring Laser Fiber Gyro."

The **Liquid Crystal Fiber Optics Large Screen Display Panel** is designed to showcase alphanumeric characters based on computer-originating signals. This technology allows the LCD panel to vary its opacity, while tapered fiber optics extend from the panel to the display screen. The design features two operational modes: one employs high-intensity light from behind the screen through the fiber optics, while the other reflects light from a surface behind the liquid crystal panel. This versatility enables the creation of a matrix of liquid crystal panels, facilitating an expanded visual presentation that ensures multiple observers receive clear and reliable information.

The **Pulsed Ring Laser Fiber Gyro** represents a significant improvement in gyroscopic technology. This invention utilizes pulsed optical signals traveling in an optic loop. By employing optical amplifiers and a beamsplitter/coupler, it generates clockwise and counterclockwise pulsed optical signals that are fed to a detector. The distinct feature of this gyro is its ability to detect low rotation rates more effectively than traditional continuous wave laser gyros, thanks to minimal coupling between the different modes of signal propagation.
