    Abstract: Devices that record data from a space, such as audio or video devices having microphones and/or cameras, may have a privacy mode which allows a user to temporarily prevent the device from recoding audio or video of the space. The privacy mode may be a privacy cover, button, airgap, or other mechanism to obfuscate the acoustic or video signal, or to remove power and/or communication from the camera, microphone, control circuit, or to the entire device itself. Additionally, the privacy mode may be remotely enabled for multiple devices in a space.

  • Publication number: 20190288554
    Abstract: A load control system may include control devices capable of being associated with each other at one or more locations for performing load control. Control devices may include control-source devices and/or control-target devices. A location beacon may be discovered and a unique identifier in the location beacon may be associated with a unique identifier of one or more control devices. Upon subsequent discovery of the location beacon, the associated load control devices may be controlled. The beacons may be communicated via radio frequency signals, visible light communication, and/or audio signals. The visible light communication may be used to communicate other types of information to devices in the load control system. The visible light communication may be used to identify link addresses for communicating with load control devices, load control instructions, load control configuration instructions, network communication information, and/or the like.

  • Publication number: 20190268802
    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.

  • Publication number: 20190250201
    Abstract: A control module for a lighting fixture may include an input circuit (e.g., a wireless communication circuit) that may be susceptible to noise generating by a noise-generating source (e.g., a lighting control device in the lighting fixture). The control circuit may execute a self-test procedure to determine if the magnitude of the noise is acceptable or unacceptable for normal operation of the control module. During the self-test procedure, the control circuit may measure a noise level at a connection of the input circuit and determine if the noise level causes the self-test procedure to fail. The control circuit may control the lighting load to multiple intensities, measure noise levels of the output signal at each intensity, and process the noise levels to determine if the test has passed or failed. The control circuit may illuminate a visual indicator to provide an indication that the self-test procedure has failed.

  • Publication number: 20190230762
    Abstract: 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.

  • Publication number: 20190191520
    Abstract: A load control device (e.g., an LED driver) for controlling the intensity of a lighting load (e.g., an LED light source) may provide a wide output range and flicker-free adjustment of the intensity of the lighting load. The load control device may comprise a load regulation circuit, a control circuit, and a filter circuit (e.g., a boxcar filter circuit) that operates in a different manner in dependence upon a target current. When the intensity of the lighting load is near a low-end intensity, the control circuit may adjust an operating frequency of the load regulation circuit in response to the target current, and may control the filter circuit to filter a current feedback signal during a filter window that repeats on periodic basis. When the intensity of the lighting load is near a high-end intensity, the control circuit may control the filter circuit to constantly filter the current feedback signal.

  • Publication number: 20190166665
    Abstract: A load control device for controlling the amount of power delivered to an electrical load (e.g., an LED light source) includes first and second semiconductor switches, a transformer, a capacitor, a controller, and a current sense circuit operable to receive a sense voltage representative of a primary current conducting through to a primary winding of the transformer. The primary winding is coupled in series with a semiconductor switch, while a secondary winding is adapted to be operatively coupled to the load. The capacitor is electrically coupled between the junction of the first and second semiconductor switches and the primary winding. The current sense circuit receives a sense voltage and averages the sense voltage when the first semiconductor switch is conductive, so as to generate a load current control signal that is representative of a real component of a load current conducted through the load.
