| 20080276154 | LIGHTING CONTROL PROTOCOL - A digital lighting control network protocol with forward and backward frames, each of the frames including an error check code. A no-acknowledgment (NAK) signal is sent from a receiving node to a transmitting node responsive to the error check code. An interface circuit of the receiving node may include an energy storage section to store at least some energy from the network while receiving digital signals, and an output section to transmit digital signals to the network using the stored energy. The interface circuit may also include a high voltage buffer circuit. The transmitting node may send forward frames to receiving nodes based on device type. | 11-06-2008 |
| 20100102962 | OCCUPANCY SENSING WITH SELECTIVE EMISSION - An occupancy sensing system includes a driver to emit energy in a space, and a sensor to detect energy reflected within the space. An electrical load for the space is controlled in response to an occupancy condition determined in response to the detected energy. The driver may be selectively de-energized. In some embodiments, the driver may be de-energized during all or a portion of an unoccupied period. In other embodiments, the driver may be de-energized during all or a portion of an occupied period. In some further embodiments, the driver may be de-energized in response to detecting other sources of the type of energy emitted by the driver. | 04-29-2010 |

| 20080273754 | APPARATUS AND METHOD FOR DEFINING AN AREA OF INTEREST FOR IMAGE SENSING - A method for defining an area of interest or a trip line using a camera by tracking the movement of a person within a field of view of the camera. The area of interest is defined by a path or boundary indicated by the person's movement. Alternatively, a trip line comprising a path between a starting point and a stopping point may be defined by tracking the movement of the person within the camera's field of view. An occupancy sensor may be structured to sense the movement of an occupant within an area, and to adjust the lighting in the area accordingly if the occupant enters the area of interest or crosses the trip line. The occupancy sensor includes an image sensor coupled to a processor, an input facility such as a pushbutton to receive input, and an output facility such as an electronic beeper to provide feedback to the person defining the area of interest or the trip line. | 11-06-2008 |
| 20090212708 | MULTI-ZONE CLOSED LOOP DAYLIGHT HARVESTING HAVING AT LEAST ONE LIGHT SENSOR - A multi-zone daylight harvesting method and apparatus having a closed loop system utilizing a single light sensor is disclosed herein. This light control system includes an ambient light sensor connected to a detection circuit for detecting the amount of ambient light within a given zone and converting the light signal to an digital one. A control device couples to receive a predetermined rate of change for each respective zone from a storage unit along with the converted digital signal. The control device connects each zone of a plurality of electrical loads to control the power supplied to the electrical load at the predetermined corresponding rate of change and responsive to the amount of ambient light detected. | 08-27-2009 |
| 20100006749 | CLOSED LOOP DAYLIGHT HARVESTING LIGHT CONTROL SYSTEM HAVING AUTO-CALIBRATION - An apparatus and method for enabling an automatic calibration sequence for a light control system having a daylight harvesting scheme is disclosed herein. An ambient light sensor connects to a detection circuit for detecting the amount of ambient light within a given zone. A microprocessor connects between the detection circuit and a dimming circuit for providing control to initiate dimming and to start the auto-calibration sequence. Responsive to the amount of ambient light detected, the dimming circuit controls the power supplied to a plurality of electrical loads. A storage unit connects to the microprocessor for storing minimum light levels assessed during the auto-calibration sequence wherein the ambient light levels are monitored for a predetermined amount of time to determine the lowest level of ambient light generated for the purpose of setting and storing a target voltage level associated with such. | 01-14-2010 |
| 20110090042 | WIRELESS DEMAND RESPONSE SYSTEM - A wireless demand response endpoint includes a power switch and a wireless receiver to control the power switch in response to a wireless demand signal. The wireless demand signal may be transmitted at the same premises as the endpoint. One or more wireless endpoints at the premises may be configured to respond to the wireless demand signal. The wireless demand signal may be transmitted automatically, manually, or in other modes. Power switching may be on/off, dimming, etc. | 04-21-2011 |
