Title: Innovations of Russell E Hammond
Introduction
Russell E Hammond is a notable inventor based in La Jolla, CA (US). He holds a total of 11 patents that showcase his contributions to the field of technology and engineering. His work primarily focuses on advancements in electronic components and systems.
Latest Patents
One of his latest inventions is the Digital Drive Sonar Power Amplifier. This invention integrates an amplifier directly into an electromechanical transducer assembly. In one embodiment, power from a power supply is supplied to an electromechanical amplifier that includes bridge circuits, which directly drive the transducer elements. Each transducer element can include its own co-located switching network, such as a bridge circuit, that can be used with other system components to control when and for how long a voltage of equal magnitude and of either a positive or negative polarity is selectively directed to the element. This allows the element to expand or contract in relation to a signal desired to be acoustically transmitted. The bridge circuit also permits an output that is “open” and one that allows a dissipation of transducer element charge.
Another significant invention is the Voltage Controlled Variable Inductor. This device provides a rapidly variable inductance for high power frequency-dependent circuit applications. Continuously variable inductance values with a high Q factor are obtainable with minimal control power.
