Abstract: A wireless device may receive packets according to a protocol, such as Bluetooth, and may rapidly react to receive an interfering RF packet instead of dropping the first RF packet and the interfering RF packet, to decrease message delay due to collisions in high device density environments. When a received signal strength indicator (RSSI) difference between the interfering RF packet and the first RF packet exceeds a threshold, the device may detect the interfering packet and resync a portion of its circuitry to lock on to and receive the interfering packet. The wireless receiver may detect the interfering RF packet by detecting one or more of: a specific resync byte sequence, an increase in RSSI, or a phase shift. Additionally, a wireless device may add the specific resync byte sequence to an RF packet of a standard protocol.

Abstract: 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.

Abstract: A battery-powered, motorized window treatment may include a fascia that pivots between a conceal position wherein the fascia covers a window treatment assembly and a battery compartment, and an expose position wherein the fascia does not cover the battery compartment. The fascia may be a two part fascia that includes an arm and a cover that pivots relative to the arm when the battery compartment is operated between respective opened and closed positions. The arm may be attached to the battery compartment such that the arm remains in a fixed orientation relative to the battery compartment. The arm and the cover may define complementary pivotally interlocking connectors that define a pivot axis about which the cover may pivot relative to the arm. The fascia may be configured to generate a perceptible indication when the fascia pivots into the conceal position, and/or when the fascia pivots into the expose position.

Abstract: An illumination device, system, and method are provided herein for emulating sunlight along a daytime or nighttime locus. Color temperature is determined using a first color temperature curve that includes data representative of a first color temperature as a function of a time of day. In response to a request to a change in brightness of one or more LED chains, a target color temperature output as a function of the current time of day is determined using a second color temperature curve based on the requested change in brightness. The second color temperature curve includes the target color temperature corresponding to the determined current time of day. The target color temperature output includes a lesser change in color temperature at solar noon than the change in color temperature at sunrise and sunset.

Abstract: A load control device may control power delivered to an electrical load from an AC power source. The load control device may include a controllably conductive device adapted to be coupled in series electrical connection between the AC power source and the electrical load, a zero-cross detect circuit configured to generate a zero-cross signal representative of the zero-crossings of an AC voltage. The zero-cross signal may be characterized by pulses occurring in time with the zero-crossings of the AC voltage. The load control device may include a control circuit operatively coupled to the controllably conductive device and the zero cross detect circuit. The control circuit may be configured to identify a rising-edge time and a falling-edge time of one of the pulses of the zero-cross signal, and may control a conductive state of the controllably conductive device based on the rising-edge time and the falling-edge time of the pulse.

The electrical load control device may control, for example, motorized window treatments (e.g., shades), lighting controls, and/or sensors (e.g., occupancy, radio window, daylight, etc.). For example, a load control device comprising a motorized window treatment may control the position of a covering material in the window treatment. The computing device may comprise a processor and/or a graphical user interface (GUI). The computing device may be a server and/or a user device, such as a wireless user device (e.g., a cellular phone, tablet, or laptop computer). The computing device may be configured to provide graphical representations that may be displayed on a GUI based on load control information.

The antenna may provide the dimmer with a first wireless transmission range. The dimmer may include a faceplate that cooperates with the antenna to provide the dimmer with a second wireless transmission range that is broader than the first wireless transmission range. The dimmer may include a button assembly that is supported independently of the yoke.

Abstract: A control device for a ceiling fan may have a motor drive circuit configured to control a rotational speed of a motor of the ceiling fan, an occupancy sensing circuit, and a control circuit configured to adjust the rotational speed of the motor in response to a detected occupancy or vacancy condition. The control circuit may process the signals generated by the occupancy sensing circuit to eliminate the effects of vibrations and/or wobbling of the ceiling fan. The control circuit may control the motor drive circuit to adjust the rotational speed of the motor in response to an accelerometer to minimize the magnitude of the wobble of the ceiling fan. The control circuit may be configured to learn a preferred rotational speed for the motor. The control circuit may also be configured to control the rotational speed of the motor to affect a thermal comfort level of an occupant.
