Latest Patents

Among his latest patents is the "Passive Optical Proximity Fuze," which is an onboard system designed to determine the slant range to a ground impact point of a ballistic vehicle. This system employs two infrared sensors that view the ground at a very small divergent angle relative to each other. The off-axis displacement angle is minimal, allowing for the detection of infrared landmarks at low approach angles. The system utilizes a correlator to measure the time delay between successive observations of ground landmarks, enabling the computation of slant range without requiring knowledge of any angles involved.

Another significant patent is the "Detonation System and Method," which involves a remotely situated detonator that is acoustically triggered to detonate explosives. This system uses a conduit capable of propagating an acoustic wave to transmit a precoded acoustic wave signal from a transmitter to a receiver. The receiver is equipped with means to convert the precoded acoustic wave signal into an electrical output signal to actuate the detonator, along with decoding means to filter out noise signals. For safety, time delay means may be included to postpone the generation of acoustic wave signals until after a predetermined time period. This detonation system can be utilized to rejuvenate or activate subterranean resources such as petroleum, gas, geothermal steam, or water.
