    摘要： In one embodiment, a system may be provided that includes a circuit that is electrically coupled to a line. The circuit generates a direct current signal on the line, where the direct current signal has a period that includes a charge cycle and a discharge cycle. The circuit charges the line in the charge cycle and ceases to charge the line in the discharge cycle in order to generate the direct current signal. The line fails to fully discharge for at least a portion of the discharge cycle. To receive data from the line, the circuit detects a variation in a discharging of the line in the discharge cycle.

    摘要： A system for determining operating points of a photovoltaic array may power a load with the photovoltaic array and an alternate power source concurrently. One or more operating points of the photovoltaic array may be detected by adjusting the amount of power that the alternate power source supplies to the load while continuing to power the load with the alternate power source and the photovoltaic array. The operating points may be stored in a calibration table. Alternatively or in addition, the operating points may be detected by altering the amount of power that a battery charger receives from a photovoltaic array while the photovoltaic array powers the battery charger and the load concurrently.

    摘要： A power device may include channels coupled to conductors in lines, where each one of the channels is coupled to a different one of the lines than the other channels and where the channels deliver direct current power signals over the conductors to the load devices. Each one of the load devices may be powered by a different one of the direct current power signals. The power device may include a power communicator that communicates with the load devices over the conductors that propagate the direct current power signals. The power communicator may determine a target power level for the load devices based on the communication over the conductors. The load device may adjust an amount of power in the direct current power signals in order to match the target power level.

    摘要： In one example, an electric circuit may be provided that is coupled to a line. The electric circuit may include a switch connected in series with a load, where the switch and the load are in series between two conductors of the line. The line may provide power to the load. The electric circuit may also include a resistive element connected in parallel with the switch and in series with the load. The switch may be configured to short circuit the resistive element when closed such that the voltage on the line varies between two voltage levels when the switch is opened and closed. The line provides power to the load when the switch is opened and when the switch is closed.

    摘要： A system may be provided for controlling an amount of light generated by multiple fluorescent lamps based on a desired light level. A dimming circuit may vary the amount of light generated by at least one of the fluorescent lamps based on the desired light level if the desired light level is in a first range of light level values. The fluorescent lamps remain lit as the amount of light generated by the lamps is varied. A switch circuit may switch off a first subset of the fluorescent lamps while a second subset of the fluorescent lamps remains lit if the desired light level is in a second range of light level values. The second range of light level values indicates less light is desired than the first range of light level values indicates.

    摘要： A system and method for commissioning a lighting system is provided in which signals from light sensors are filtered in order to determine whether light is received from light fixtures in the lighting system or from external light sources. Alternatively or in addition, signals from light sensors may be filtered to determine the amount of light from external light sources. By filtering the signals from the light sensors, an identification of which light fixtures are colocated with which light sensors may be made even in the presence of light received from external light sources or light from multiple light fixtures in the lighting system. Physical locations of light fixtures and/or sensors may be determined based on detecting the amount of light received from external light sources.

    摘要： In one embodiment, an apparatus includes a circuit coupled to a line, where the circuit may power a device, and where the power is transmitted to the device over the line as a pulse-width modulated signal. The circuit may set a duty cycle of the pulse-width modulated signal in order to transmit a determined power level to the device. The apparatus may vary a frequency of the pulse-width modulated signal to transmit data to the device while the duty cycle of the pulse-width modulated signal is fixed in order to continue to transmit the determined power level to the device. A variation in the frequency of the pulse-width modulated signal may be detectable by the device and represents at least a portion of the data.
