ALEXANDRIA, Va., March 17 -- United States Patent no. 12,579,671, issued on March 17, was assigned to Analog Devices Inc. (Wilmington, Mass.).

"Miniaturized phase calibration apparatus for time-of-flight depth camera" was invented by Tzu-Yu Wu (Wayland, Mass.) and Charles Mathy (Arlington, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and apparatus for phase calibration in time-of-flight cameras. In particular, systems and methods are presented for a miniaturized cover design that at least partially encloses the time-of-flight (ToF) module. The geometry of the miniaturized design causes the signals reflected from the calibration device back to the ToF imager to have essentially the same time-o...
