Patent number: 10634380Abstract: Disclosed herein are embodiments of an occupancy monitoring system. The occupancy monitoring system includes a thermal sensor configured to monitor a gate (e.g., entry way) to a space. The thermal sensor includes a pixel array that generates a pixel value for each pixel in the pixel array, and the pixel value corresponds to a quantity of heat or thermal information detected by a pixel. The occupancy monitoring system acquires pixel values for the pixels of the pixel array. The occupancy monitoring system determines whether there is a change in occupancy of the space based on changes to a first region (or first pixel cluster) of the pixel array and a second region (or second pixel cluster) of the pixel array over time. The occupancy monitoring system may adjust lighting, temperature, and/or security systems for the space as the occupancy changes.Type: GrantFiled: April 10, 2018Date of Patent: April 28, 2020Assignee: OSRAM SYLVANIA Inc.Inventors: Marijan Kostrun, Anant Aggarwal, Richard C.
