摘要： Described herein is an audio device with a microphone which may adapt the audio output volume of a speaker by either increasing or decreasing output volume based on an audio input volume from a user and a distance from the user to the audio device. The audio device may also adapt its output volume to lower the audio output based on detecting one or more interruptions including occupancy and acoustic sounds.

摘要： A control device for controlling power delivered to an electrical load may illuminate an area around a button of the control device, such as a gap formed between the button and an opening of a faceplate of the control device. The control device may illuminate the gap to provide a nightlight feature, to provide feedback (e.g., a status of the electrical load), and/or to indicate a selected preset. The button may have a cap portion that may be actuated by a user and a diffuser portion that may contact a rear surface of the cap portion and may conduct light emitted by an internal light source to illuminate the gap around the button.

摘要： A load control device (e.g., a switching device) for controlling power delivered from an AC power source to an electrical device (e.g., a lighting load) may be configured to detect that a relay is stuck closed and attempt to fix the relay. The relay of the load control device may be adapted to be coupled between the source and the electrical device to control the power delivered to the electrical device so as to generate a switched-hot voltage. The load control device may comprise a detect circuit configured to generate a detect signal indicating a magnitude of the switched-hot voltage, and a control circuit configured to monitor the detect signal. The control circuit may be configured to determine that the relay is stuck closed in response to the detect signal, and to control the relay in order to attempt to fix the relay by repeatedly closing and opening the relay.

摘要： A faceplate remote control device may be attached to a wall-mounted mechanical light switch that has a toggle actuator. The faceplate remote control device may include a toggle indicator that detects operation of the toggle actuator of the mechanical switch. The toggle indicator may cause the generation of an indication of detected operation of the toggle actuator. The toggle indicator may comprise a sliding member that is configured to move with the toggle actuator. The toggle indicator may comprise an obstruction detection device that includes an infrared (IR) transmitter and an IR receiver. The faceplate remote control device may include a control circuit and a wireless communication circuit. The control circuit may be configured to cause the wireless communication circuit to transmit one or more messages in response to detecting operation of the toggle actuator of the mechanical switch.

摘要： Provided herein are examples of a remote control device that provides a retrofit solution for an existing switched control system. The remote control device may comprise a control circuit, a rotatable portion, a magnetic ring coupled to the rotatable portion, and first and second Hall-effect sensor circuits configured to generate respective first and second sensor control signals in response to magnetic fields generated by the magnetic elements. The control circuit may operate in a normal mode when the rotatable portion is being rotated, and in a reduced-power mode when the rotatable portion is not being rotated. The control circuit may disable the second Hall-effect sensor circuit in the reduced-power mode. The control circuit may detect movement of the rotatable portion in response to the first sensor control signal in the reduced-power mode and enable the second Hall-effect sensor circuit in response to detecting movement of the rotatable portion.

摘要： A control device may have a plurality of buttons that may be backlit to multiple levels, such as first, second, and third adjacent buttons positioned in order, and first, second, and third LEDs positioned to illuminate a respective button. The control device may be configured to illuminate the first LED to a first LED illumination intensity to illuminate the respective button to a first surface illumination intensity; illuminate the third LED to a second LED illumination intensity to illuminate the respective button to a second surface illumination intensity; and illuminate the second LED to a third LED illumination intensity to illuminate the respective button to the second surface illumination intensity. The third LED illumination intensity may be less than the second LED illumination intensity, which may be less than the first LED illumination intensity, and the second surface illumination intensity may be less than the first surface illumination intensity.

摘要： A temperature control system may include a temperature control device, an electrical wall box having a hole for passing a wire or cable into the wall box, and a gland configured to be inserted into the hole of the wall box. The temperature control device may include a temperature sensor. The wall box may be configured to be mounted to a wall. The temperature control device may be configured to be mounted to the wall box such that the temperature sensor is located within the wall box. A wire or cable may be passed from a wall cavity of the wall, through the gland once inserted into the hole of the wall box, into an interior of the wall box, and attached to the temperature control device. The gland and the wall box may be configured to prevent air within the wall cavity from entering the wall box when the wire or cable is passed into the wall box.
