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 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.

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 repeater, useable for connecting switches in a data communication network, is provided in a distributed and/or modular fashion. The repeater includes a plurality of separate and distinct components or modules connected to or at least partially housed in, the various switches which the repeater modules couple. Preferably, the repeater autodetects and/or autoconfigures some or all aspects of repeater operations, such as detecting and/or configuring in response to appropriate or approved cable-type connections. A conductive, sealing member on a cable connector substantially reduces or eliminates EMI.
