The technology of smart lighting detecting human occupancy
US Patent titled “Sensory Lighting System and Method for Characterizing an Illumination Space” was awarded to LESA' faculty and graduate students from Rensselaer Polytechnic Institute and Boston University. The patent explains the process of LED lighting system in a space that can detect occupants’ presence, location and position without the use of cameras so that guarding the privacy of the room’s occupants.
Robert Karlicek, LESA Director says, “Every illuminated space has an optical “fingerprint”. “If nothing is moving within the space, then the distributions of light and color in the space don’t move. Using a limited number of low cost sensors mounted on the ceiling, we can measure the optical fingerprint of any space and determine when and how things move within it”. Time-of-flight (ToF) sensing technology is being used to preserve privacy- occupancy sensing by the patented technology. ToF sensors utilize light to measure reasonably accurate physical distance. It allows one to map the space, and determine the location as well as height (sitting, standing, prone) of individuals and other objects in the room. Karlicek says “Imagine a building management system in an environment such as a healthcare facility, office or retail space, warehouse, airport, or library...
