  • Patent number: 7277012
    Abstract: A motion sensing system device and method which utilize dispersed ultrasonic radiation is disclosed. The system preferably comprises a low profile sensor unit configured to couple to a ceiling position. The sensor unit comprises an ultrasonic transmitter and an ultrasonic receiver and a pair of acoustic reflectors positioned in a transmitting path of the ultrasonic transmitter and a receiving path of the ultrasonic receiver for generating and detecting the ultrasonic radiation in a broadcast field. The acoustic reflectors preferably comprise cones, conical cross-sections and/or combinations thereof which are integral with the ultrasonic transmitter and the ultrasonic receiver and/or are coupled to a housing structure for positioning the acoustic reflectors in the transmitting and/or receiving paths. The sensor unit also preferably comprises a circuit for driving the transmitter and for detecting motion by detecting changes in the receiver signal.

  • Patent number: 6415984
    Abstract: Ceiling fan operation control for turning the fan on and off based on a passive infrared sensor, combined with a temperature sensor to regulate, the speed of the fan. The passive infrared sensor, the temperature sensor and controls for both are in a housing directly mounted to the fan motor of the ceiling fan. Me controls can be set screws covered by a removable cap. The passive if sensor can include a fresnal lens for sensing a 360 degree circumference beneath the fan, and a photo-optical sensor such as a photocell, which suspends ceiling fan control changes for allowing the fan to continue operation when the room is dark and occupants may be sleeping.
