US Patent Issued to STMicroelectronics International on Sept. 30 for "Presence detection with signal regularization and edge detection" (Italian Inventors)

ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,429,584, issued on Sept. 30, was assigned to STMicroelectronics International N.V. (Geneva).

"Presence detection with signal regularization and edge detection" was invented by Piergiorgio Arrigoni (Domodossola, Italy), Stefano Paolo Rivolta (Desio, Italy) and Marco Bianco (Cesano Boscone, Italy).

According to the abstract* released by the U.S. Patent & Trademark Office: "The present disclosure is directed to human presence detection with an infrared sensor. The human presence detection utilizes signal regularization and edge detection to minimize the effect of drift on the human presence detection. The human presence detection is accurate regardless of changes in ambient temperature...
