US Patent Issued to STMicroelectronics (Research & Development) on Dec. 2 for "Quantum film direct time of flight sensor circuit for low cost short wave infrared operation" (British Inventor)

ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,487,342, issued on Dec. 2, was assigned to STMicroelectronics (Research & Development) Ltd. (Marlow, Great Britain).

"Quantum film direct time of flight sensor circuit for low cost short wave infrared operation" was invented by Neale Dutton (Edinburgh, Great Britain).

According to the abstract* released by the U.S. Patent & Trademark Office: "A time-of-flight system includes an emitter-circuit generating and directing pulses of light toward a target, and a receiver-circuit including a photodetector coupled between a bias node and a sensing node to detect pulses that have reflected off the target, a comparison circuit comparing a sense voltage at the sensing node to a reference, a timi...
