Latest Patents

One of his latest inventions is the involute spiral wrap device. This device utilizes two pairs of spiral wrap members connected at opposite ends of a common rotational shaft. It can operate in either an expansion mode or a hybrid mode, where each pair functions as a compressor and expander, respectively. In expansion mode, electric current is generated via a generator responsive to shaft rotation. The hybrid mode allows for a balance of power between the expander and compressor, with the motor/generator either functioning as a motor or converting energy into electricity. The device is designed to be hermetically sealed, promoting contamination-free operation, and includes features such as a throttle valve and a differential pressure valve for optimal performance.

Another significant patent is a power supply that efficiently manages heavy start-up power draws from a power grid. This invention allows for the initial start-up of a load using the grid and subsequently switches to a generator for lower power draw operation. The power supply includes a conductor for grid connection, an electrical power generation device, and a switching mechanism to isolate and connect the necessary components. This innovation also serves as a backup power source during grid failures, ensuring reliability and efficiency.
