Latest Patents

One of his latest innovations is the "Bang-bang Laser Spot Tracker," a digital tracking system designed for remote laser designated targets. This system effectively addresses position, rate, and acceleration errors by responding to the sign of the error signal rather than the amplitude of the received output. By analyzing consecutive zero crossings of the boresight, the technology optimizes the tracking performance, enabling accurate control of the optics involved. Moreover, it computes the velocity error based on signal detections, ensuring a composite tracking error signal is generated for the gimbal drive mechanism controlling the optics.

Another significant patent involves the development of "Crystals for Ultraviolet Light Filters." These unique crystals, composed of a solid-solution of NiSiF.sub.6 6H.sub.2 O, offer exceptional filtering properties for ultraviolet (UV) light. Capable of withstanding high temperatures up to 115 degrees Celsius, these materials are particularly beneficial in sensing devices aimed at detecting UV light in missile warning systems.
