His work primarily focuses on enhancing the functionality and efficiency of various systems, particularly in the aerospace industry.
Latest Patents
Bartholomew's latest patents include a position sensor using optical fibers and a variable filter. This innovative optical position sensor is designed to sense the position of an object that moves along a motion axis. The sensor consists of a light source, a support member, a beamsplitter, a variable filter, and a processor. The light source generates an optical beam directed to the beamsplitter, which converts the beam into a reference beam and a subject beam. The variable filter, which is coupled to the object, modulates the subject beam based on the object's position. The processor then compares the subject beam to the reference beam to determine the object's position.
Another significant patent is the aircraft fiber optic control device. This device is specifically adapted for connecting to a servovalve and provides an optical-thermal-mechanical converter for driving a servovalve powered by the aircraft's hydraulic system. This innovation enhances the control and efficiency of aircraft systems.
