Latest Patents
One of his latest patents is a non-intrusive beam power monitor for high power pulsed or continuous lasers. This innovative system and method utilize a photodiode positioned within the laser cavity to monitor the output of the laser. The photodiode is strategically placed outside the laser beam to detect extraneous light generated in the cavity, which correlates directly with the laser beam output power level. Additionally, this system allows for monitoring the phase of the laser output beam in relation to a modulated control signal through the photodiode monitor.
Another significant patent by Hawsey involves disc rotors with permanent magnets for brushless DC motors. This design is intended for an autonomous underwater vehicle. The motor features four flat stators arranged in a stacked configuration, with pairs of stators spaced apart. Each stator includes a tape-wound stator coil, and the design incorporates two flat rotors that contain an annular array of embedded permanent magnets. The motor's unique structure allows for the rotation of two concentric shafts in opposite directions, enhancing its efficiency and functionality.
