Latest Patents
One of his latest patents is the "Multichannel SQUID flux meter having multiplexed SQUID flux sensors." This invention involves a plurality of SQUID flux sensors that are supplied with their respective bias currents simultaneously from a bias source. A superconducting multiplexer is utilized to multiplex the output signals of the SQUID flux sensors during the time when the bias currents are applied. The multiplexer, which operates in a room-temperature environment, distributes each multiplexed output signal to corresponding output terminals. This innovative design allows for accurate measurement of external magnetic flux to each SQUID flux sensor.
Another notable patent is the "Amplitude variable pulse generating circuit." This circuit features two voltage supply sources, where the first provides a variable voltage to determine the output pulse's amplitude. The second voltage source is a fixed voltage that is lower than the first. This configuration enables quick voltage adjustments, improving the resolution of supersonic wave devices, particularly in diagnostic applications.
