US Patent Issued to Alps Alpine on Aug. 12 for "Capacitance detection device, capacitance detection method, and input device" (Japanese Inventors)

ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,385,958, issued on Aug. 12, was assigned to Alps Alpine Co. Ltd. (Tokyo).

"Capacitance detection device, capacitance detection method, and input device" was invented by Kiyoshi Sasai (Miyagi-ken, Japan) and Akihisa Iikura (Miyagi-ken, Japan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A calculation unit calculates a detection value of a capacitance of a capacitor based on a detection signal. A correction unit repeatedly performs a shift to a correction mode. When the correction mode is entered, the correction unit controls an AC voltage output unit so that a difference between amplitudes of first and second AC voltages changes, and obtains a correctio...
