    Abstract: In some aspects, a relay control device includes a processor and a timer. The processor is electrically connectable to a relay that controls current flow to a load device. The processor causes the relay to be actuated at a first point in time so that a current flows to the load device. The processor determines an actuation duration for the relay from a measurement of the load current that is obtained with a current sense component. The processor determines a frequency of an input voltage or current from the measured load current. The processor synchronizes the timer with this frequency and identifies a zero-crossing point for a second load current based on the synchronized timer. The processor subsequently causes the relay to be actuated at a time that is offset from the zero-crossing point by the actuation duration.

    Abstract: A system for providing power from an AC power supply to an external load. The system includes a current limiter circuit, connected to an input of a switched-mode power supply. The system includes the switched-mode power supply that provides a first voltage signal and a second voltage signal. The system includes a supervisor circuit that is connected to the first output of the switched-mode power supply and coupled to a relay control circuit. The supervisor circuit monitors the first voltage signal and enables the relay control circuit. The relay control circuit provides a first voltage corresponding to the first voltage signal to a first voltage rail and provides a second voltage corresponding to the second voltage signal to a second voltage rail. A relay powered by a connection to the first voltage rail or the second voltage rail connects the AC power supply to an external load.

    Abstract: An intelligent lighting system may be installed using pre-existing electrical wiring, such as in a construction or retrofit environment. An intelligent lighting controller and an intelligent lighting fixture may be connected via electrical wiring that is configured for transmitting AC power signals. A commissioning signal may be transmitted to the intelligent lighting fixtures via the electrical wiring. In some cases, the intelligent lighting controller modifies portions of the AC power signal to indicate the commissioning signal. The intelligent lighting fixtures may receive the commissioning signal via the electrical wiring. In some cases, each intelligent lighting fixture that is connected to the electrical wiring, such as each intelligent lighting fixture on a lighting circuit in a room, receives the commissioning signal.

    Abstract: A lighting relay panel may include lower-cost features or components related to improved safety and reliability. In some cases, the relay panel includes a power supply capable of protecting the panel from high-voltage and high-current transients. A microcontroller may determine a power interruption based on a zero-cross signal received from the power supply, and may also configure latching relays during the interruption. In some implementations, the relay panel includes a relay sense circuit that is capable of receiving actuation signals from multiple relays connected to different phases of a power signal, and the microcontroller may synchronize or repeat the actuations based on a signal from the relay sense circuit. The microcontroller may generate relay addresses based on the relay positions within the relay panel. In some cases, the relay panel may include isolation circuits that are capable of providing an isolated control signal having an improved voltage range.

    Abstract: A lighting control system allows user control of the color features of controllable light fixtures. Controlled color features may include the color, color temperature, tint, or other qualities related to the color of the light. Control of the color features may be independent from control of the intensity of the light fixtures. The system may use light-emitting diode (LED) light fixtures, or fluorescent or incandescent light fixtures. The system may enable control of the color feature using a controllable driver/ballast and a dimmer control. The color feature may be adjusted along a color path of adjacent values in a suitable color space model.
