Presence adaptive lighting control strategies are known to be very effective in reducing energy consumption in buildings. Ultrasonic array sensors have been proposed for reliable presence sensing. Systems and methods are disclosed by which additional sensing functionalities may be enabled for providing new control functions, with the array sensor as basic sensing platform. In particular, hybrid sensing that combines portable sensors (possibly, user enabled) and fixed-infrastructure sensors is considered. Applications are, for example, active presence sensors in lighting control applications. |
