Latest Patents

One of his latest patents is the "Connecting apparatus for electro-acoustic devices." This invention features modified configurations for electrical connectors to ceramic transducers, designed to reduce failure rates due to fatigue during transducer operation. The modifications address issues such as tensile forces acting on electrical wires connected to ceramic electrodes and unreliable solder joints. By utilizing star and pin configurations of wire soldered to ceramic transducers, the invention effectively controls the position of the wires, thereby reducing tensile forces. Additionally, plug connectors employ pressure contacts between the ceramics, eliminating the need for solder joints.

Another significant patent is the "Current source preamplifier for hydrophone beamforming." This preamplifier is designed for beamforming hydrophone signals within a sonar array. It employs an amplifier that provides a current-source type of output, which helps avoid the substantial signal loss typically associated with voltage-source amplification. To ensure the stability of gain required for this operation, the invention incorporates a negative feedback system that can be easily adjusted by selecting appropriate resistors. The advantages of this invention include cost savings, reduced size and power requirements, and improved signal-to-noise ratio.
