Abstract: A wall box may provide adjustable support for a control device, such as a keypad, to allow for level alignment of the control device when mounted to the wall box. The wall box may have an adjustable support frame to which the control device may be mounted. When the control device is mounted to the support frame of the wall box, the support frame may be rotated to adjust the alignment of the control device. In addition, the wall box may comprise one or more projections configured to be received in respective detents in notched surfaces of the control device to allow for adjustment of the alignment of the control device. Further, the wall box may have a modular assembly and may be constructed from a central portion and two side portions at the time of installation of the wall box.

Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.

Abstract: An illumination device and method are provided herein for calibrating individual LEDs in the illumination device to obtain a desired luminous flux and a desired chromaticity of the device over changes in drive current, temperature, and over time as the LEDs age. The calibration method may include subjecting the illumination device to a first ambient temperature, successively applying at least three different drive currents to a first LED to produce illumination at three or more different levels of brightness, obtaining a plurality of optical measurements from the illumination produced by the first LED at each of the at least three different drive currents, obtaining a plurality of electrical measurements from the photodetector and storing results of the obtaining steps within the illumination device to calibrate the first LED at the first ambient temperature. The plurality of optical measurements may generally include luminous flux and chromaticity, the plurality of electrical measurements may generally include induced photocurrents and forward voltages, and the calibration method steps may be repeated for each LED included within the illumination device and upon subjecting the illumination device to a second ambient temperature.

Abstract: Motorized window treatment systems are disclosed. A motorized window treatment system may include a covering material, a sensor circuit, and a control circuit. The sensor circuit may be configured to generate sensor signals indicative of a position of the covering material. The control circuit may be configured to determine a present sensor state of the sensor circuit, determine a predicted sensor state for the sensor circuit based at least in part on a power-down position recorded at a first time and a final position recorded at a second time, compare the predicted sensor state with the present sensor state, and determine a present position of the covering material based on the comparison of the predicted sensor state and the present sensor state. Methods of adjusting a position of a covering material of a motorized window treatment also are disclosed.

Abstract: A lift cord spool assembly may be used in a motorized window treatment. The lift cord spool assembly may include a spool, a housing, and an end cap. The spool may be configured to windingly receive a lift cord of the motorized window treatment. A diameter of the spool may taper by approximately 0.5 degrees from the first end to an opposed second end. The housing may be configured to surround the spool. The end cap may be configured to attach to the housing, for example, such that the spool is retained within the housing. The end cap may include an inner surface, a shoulder, an aperture, and a guide. The guide may be configured to push the lift cord onto the spool as the lift cord is wound onto the spool. The guide may define a gradual slope around a circumference of the shoulder.

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 load control system may include multiple control devices that may send load control messages to load control devices for controlling an amount of power provided electrical loads. To prevent collision of the load control messages, the load control messages may be transmitted using different wireless communication channels. Each wireless communication channel may be assigned to a load control group that may include control devices and load control devices capable of communicating with one another on the assigned channel. A control device may send load control messages to a load control device within a transmission frame allocated for transmitting load control messages. The transmission frame may include equal sub-frames and load control messages may be sent at a random time within each sub-frame. Control devices may detect a status event within a sampling interval to offset transmissions from multiple control devices based on detection of the same event.

Abstract: A load control device for regulating an average magnitude of a load current conducted through an electrical load may operate in different modes. The load control device may comprise a control circuit configured to activate an inverter circuit during an active state period and deactivate the inverter circuit during an inactive state period. In one mode, the control circuit may adjust the average magnitude of the load current by adjusting the inactive state period while keeping the active state period constant. In another mode, the control circuit may adjust the average magnitude of the load current by adjusting the active state period while keeping the inactive state period constant. In yet another mode, the control circuit may keep a duty cycle of the inverter circuit constant and regulate the average magnitude of the load current by adjusting a target load current conducted through the electrical load.
