Abstract: An illumination system and method are disclosed for maintaining a consistent change in illumination value among a group of illumination devices whenever a change command is manually sent from a keypad to those illumination devices. The consistent change results from maintaining a common start illumination value among not only the group, but also the keypad which controls the group. From the start illumination value, the keypad can then compute an end illumination value depending upon the amount of time that an increase or decrease in illumination value button is depressed and held. Since the change command can arrive at different illumination devices within the group depending upon where each illumination device is geographically located, a masking time is reserved after the button is released so that enough time is allocated for each of the illumination devices within that group to arrive at a common end illumination value.

Abstract: 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.

Abstract: A load control device for controlling the intensity of a lighting load, such as a light-emitting diode (LED) light source, may include a power converter circuit operable to receive a rectified AC voltage and to generate a DC bus voltage, a load regulation circuit operable to receive the bus voltage and to control the magnitude of a load current conducted through the lighting load, and a control circuit operatively coupled to the load regulation circuit for pulse width modulating or pulse frequency modulating the load current to control the intensity of the lighting load to a target intensity. The control circuit may control the intensity of the lighting load by pulse width modulating the load current when the target intensity is above a predetermined threshold and control the intensity of the lighting load by pulse frequency modulating the load current when the target intensity is below the predetermined threshold.

Abstract: A manually-operated window treatment system may include a roller tube, a covering material, and a semi-rigid chain assembly. The covering material may be attached to the roller tube and may be operable between a raised position and a lowered position via rotation of the roller tube. The semi-rigid chain assembly may be configured to be operated by a user to rotate the roller tube. The semi-rigid chain assembly may be configured to limit the size of a loop that can be formed by the semi-rigid chain assembly. The semi-rigid chain assembly may be operatively coupled to a drive pulley of the window treatment system. The semi-rigid chain assembly may include flexible outer housing and a stiffening rod. The flexible housing may surround and operate along the stiffening rod. The hollow chain may include multiple links that are connected together to form a continuous loop.

Abstract: 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.

Abstract: A load control device coupled between an AC power source and an electrical load may operate in a three-wire mode or a two-wire mode based on whether the load control device is connected to a neutral side of the AC power source. The load control device may further comprise first and second zero-cross detect circuits to be respectively used in the two-wire mode or the three-wire mode, and a neutral wire detect circuit configured to generate a neutral-wire detect signal indicating whether the load control device is connected to the neutral side of the AC power source. A control circuit of the load control device may determine whether the load control device should operate in the two-wire mode or in the three-wire mode in response to the neutral-wire detect signal.

Abstract: A controllable electrical outlet may comprise a resonant loop antenna. The resonant loop antenna may comprise a feed loop electrically coupled to a radio-frequency (RF) communication circuit and a main loop magnetically coupled to the feed loop. The controllable electrical outlet may comprise one or more electrical receptacles configured to receive a plug of a plug-in electrical load and may be configured to control power delivered to the plug-in electrical load in response to an RF signal received via the RF communication circuit. The RF performance of the controllable electrical outlet may be substantially immune to devices plugged into the receptacles (e.g., plugs, power supplies, etc.) due to the operation of the resonant loop antenna. For example, degradation of the RF performance of the controllable electrical outlet may be less when the controllable electrical outlet includes the resonant loop antenna rather than other types of antennas.
