LESA’s Pod Sensors Enable Powerful Time of Flight Tracking

Time of Flight (ToF) sensing uses the speed of light to measure distance. It plays an essential role in technologies ranging from safe, autonomous self-driving cars to smart phones with facial recognition capabilities. The LESA Center has pioneered and patented (US9,363,859) the use of lighting-based ToF for privacy preserving indoor occupant position measurement. LESA’s precise pattern recognition methodology led to the development of extremely robust and proprietary algorithms that enable its ToF sensors to detect and respond to changes in occupancy instantly.
