Latest Patents

One of his latest patents is titled "System and method for the calibration of a hydrophone line array in a water-filled tank." This invention provides a method to measure the complex sensitivity of hydrophone data channels across a range of frequencies using a water-filled tank with proximate boundaries. The hydrophone array and reference hydrophone are helically affixed to a test fixture resting on a rotation platform. When submerged in the tank, the platform rotates about the contour of the platform in intervals for a predetermined time before indexing to the next angle. Signals transmitted by an acoustic projector in the tank are received on the hydrophones of the line array and the calibrated reference hydrophone. Electrical signals from the reference hydrophone are transmitted over an electrical cable to an acoustic data processor for use in calibrating the hydrophone line array.

Another notable patent is the "Vehicle launch assembly for underwater platforms." This invention includes a water tank mounted on the platform, with a plunger movably disposed in the tank, dividing it into first and second zones. The first zone communicates with the water environment, while the second zone connects to a launch tube inlet line mounted on the platform. An actuator is connected to the plunger and is operable to move it within the tank. A triggering device initiates the actuator's operation, moving the plunger to push water from the second zone to the launch tube inlet line, thereby ejecting a vehicle from the launch tube.
