MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647093316 A) filed by Signify Holding B. V. on July 31, 2026, for Facing Direction Detection.
Inventors include Yu, Jin; and Deixler, Peter.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: A method of facing direction and fall detection using a lighting system includes receiving, by a first luminaire and a second luminaire, a sound produced by a person in an area. The method further includes determining spatial directivity signatures of the sound based on sound levels of the sound as received by at least the first luminaire and the second luminaire, where the sound levels of the sound are at at least two frequencies of the sound. The method also includes estimating a facing direction of the person based on the spatial directivity signatures of the sound by executing an artificial intelligence (AI) model trained using spatial directivity signature data labelled with facing directions.
