ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,460,967, issued on Nov. 4.
"Integrated bound-mode spectral/angular sensors" was invented by Steven R. J. Brueck (Albuquerque, N.M.), Alexander Neumann (Albuquerque, N.M.) and Payman Zarkesh-Ha (Albuquerque, N.M.).
According to the abstract* released by the U.S. Patent & Trademark Office: "An occupancy sensor covering a wide field in an integrated chip is disclosed. The occupancy sensor includes an array of grating coupled waveguide sensors wherein continuous wave (cw) signals monitor an ambient light field for dynamic changes on times scales of seconds, and high frequency signals map in three-dimensions of the space using time-of-flight (TOF) measurements, pixel level electronics that...
