An occupant detection device may be configured to detect an occupant in a space where the occupant detection device is installed. The occupant detection device may include an occupant detection circuit that is configured to determine locations of one or more occupants in the space. The occupant detection device may also include a low-power detection circuit that is configured to indicate an occupancy or vacancy condition in the space. The occupant detection device may include a control circuit that is configured to determine that the low-power detection circuit indicates that there are no occupants within the space. The control circuit may determine that there is movement in an occupant map or a region of interest (ROI) as indicated by the locations of the one or occupants as determined by the occupant detection circuit. The control circuit may configure masked regions around the locations of the movement, and store the masked regions in memory. The movement detected by the occupant detection device within the masked regions may be ignored when determining an occupant count for the space.

Occupant detection device

A control device configured for use in a load control system to control an electrical load external to the control device may comprise an actuation member having a front surface defining a capacitive touch surface configured to detect a touch actuation along at least a portion of the front surface. The control device includes a main printed circuit board (PCB) comprising a control circuit, a tactile switch, a controllably conductive device, and a drive circuit operatively coupled to a control input of the controllably conductive device for rendering the controllably conductive device conductive or non-conductive to control the amount of power delivered to the electrical load. The control device also includes a capacitive touch PCB that comprises a touch sensitive circuit comprising one or more receiving capacitive touch pads located on the capacitive touch PCB and arranged in a linear array adjacent to the capacitive touch surface.

Load control device having a capacitive touch surface

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

Measuring lighting levels using a visible light sensor

A load control device adapted to be coupled between an AC power source and an electrical load for controlling the power delivered to the load includes a controller, an actuator for turning the electrical load on and off, an occupancy detection circuit, and an ambient light detector. The load control device automatically turns on the electrical load in response to the presence of an occupant only if the detected ambient light is below a predetermined ambient light level threshold. After first detecting the presence of an occupant, the load control device monitors actuations of the actuator to determine whether a user has changed the state of the load. The load control device automatically adjusts the predetermined ambient light level threshold in response to the user actuations that change the state of the load.

Method and apparatus for adjusting an ambient light threshold

A mobile device that is configured for wireless communication may be configured to operate as a remote control device in a lighting control system, controlling one or more lighting control devices of the lighting control system. The remote control device may control the light intensity in a space, for instance at a location of the remote control device, in response to an ambient light intensity measured at the remote control device. The remote control device may define a user interface for receiving an input that indicates a desired light intensity at the location. The remote control device may measure the ambient light intensity at the location via a light detector, compare the measured ambient light intensity to the desired light intensity, and cause the one or more lighting control devices to adjust the ambient light intensity at the remote control device until it agrees with the desired light intensity.

Controlling light intensity at a location

Configuration of a visible light sensor to control an electrical load in response to detection of an environmental characteristic

A control device configured for use in a load control system to control one or more electrical loads may comprise an actuation member having a front surface defining a touch sensitive surface configured to detect a point actuation along at least a portion of the front surface, a touch sensitive circuit, and a control circuit. The touch sensitive device may comprise one or more receiving capacitive touch pads located behind the actuation member and arranged in a linear array adjacent to the touch sensitive surface. The control circuit may be configured to operate using different filtering techniques based on the state/mode of the control device and/or based on whether the positions of point actuations by a user along the touch sensitive surface indicate a fine tune or gross adjustment by the user. For example, the control circuit may generate an output signal using light/no filtering or using heavy filtering.

A temperature control device (e.g., a thermostat) may be configured to control an internal heat-generating electrical load so as to accurately measure a present temperature in a space around the temperature control device. The temperature control device may comprise a temperature sensing circuit configured to generate a temperature control signal indicating the present temperature in the space, and a control circuit configured to receive the temperature control signal and to control the internal electrical load. The control circuit may be configured to energize the internal electrical load in an awake state and to cause the internal electrical load to consume less power in an idle state. The control circuit may be configured to control the internal electrical load to a first energy level (e.g., a first intensity) during the awake state and to a second energy level (e.g., second intensity) that is less than the first during the idle state.

Temperature control device with automatically adjustable backlighting

An occupant detection device (e.g., sensor) may include an occupant detection circuit (e.g., a radar occupant detection circuit) and a control circuit. The occupant detection circuit may determine the location of an occupant in a space with reference to a global coordinate associated with the detection circuit and the control circuit may transform the location of the occupant into a local coordinate system associated with a region of interest in the space. The control circuit may use the location information to determine whether the occupant has entered or left the region of interest and adjust an occupant count for the region of interest based on the determination. The control circuit may acquire knowledge about the region of interest during a configuration or commissioning procedure.

A load control system controls an electrical load provided in a space and comprises a load control device and one or more occupancy sensors. The load control device controls the load in response to the wireless control signals received from the occupancy sensors. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The load control device turns on the load in response to receiving the occupied control signal from at least one of the occupancy sensors, and turns off the load in response to receiving vacant control signals from both of the occupancy sensors. The load control device is operable to determine that no wireless control signals have been received from the occupancy sensors for the length of a predetermined timeout period and to subsequently turn off the load.

Control system with occupancy sensing

A sensor device may include a signal generator circuit configured to generate a supplemental signal that is combined with an ultrasonic reception voltage signal generated by an ultrasonic receiving element in response to received ultrasonic waves. The sensor device may comprise an ultrasonic receiving circuit configured to receive the combination of the ultrasonic reception voltage signal and the supplemental signal, and generate a detection signal that indicates when the space is occupied. The sensor device may also comprise a control circuit configured to receive the detection signal and detect an occupancy condition in the space in response to the detection signal. The combination of the supplemental signal with the ultrasonic reception voltage signal may ensure that the magnitudes of signals processed by the ultrasonic receiving circuit are large enough that the ultrasonic receiving circuit may appropriately generate the detection signal and the control circuit may detect the occupancy condition.

Sensor device having an ultrasonic receiving circuit

A sensor may be configured to determine how many people that have entered or exited a space. The sensor may comprise a pyroelectric infrared (PIR) detection circuit capable of generating different output signal patterns in response to a person entering or exiting the space. The sensor may determine whether the person has entered or exited the space based on the output signal pattern. The sensor may include a thermopile array, a radar detection circuit, or a visible light sensing circuit. The thermopile array, radar detection circuit, or visible light sensing circuit may be capable of detecting a person's location and/or movements within an area monitored by the sensor and determining, based on the detected movements, whether the person has entered or left the space. An occupant count of the space may then be determined accordingly by the sensor or by a system controller.

Occupant counting device

A load control device for controlling power delivered from an AC power source to an electrical device may be configured to conduct current through earth ground and may disconnect a switching circuit to reduce an amount of current conducted through the earth ground. The load control device may comprise a controllably conductive device configured to control the power delivered from the AC power source to the electrical device so as to generate a switched-hot voltage, a switching circuit electrically coupled with a detect circuit, and a control circuit configured to render the switching circuit conductive and nonconductive. The detect circuit may generate a detect signal indicating a magnitude of the switched-hot voltage. The control circuit may be configured to monitor the detect signal and to render the switching circuit non-conductive after detecting an edge on the detect signal to reduce the total current through the earth ground.

Load control device having a reduced leakage through ground

A visible light sensor (VLS) may be configured to sense environmental characteristics using images of a space. The VLS may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the VLS may be configured to decrease or eliminate glares. In the daylighting sensor mode and/or color sensor mode, the VLS may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the VLS may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.
