摘要： A low voltage high current bi-directional termination voltage regulator for use in a bus termination circuit in a repeater stack is disclosed that includes an operational amplifier, a bipolar transistor current source circuit, and a bipolar transistor current sink circuit. The operational amplifier is configured to source current to a first node when the output voltage at a second node is pulled below a nominal termination voltage and configured to sink current from the first node when the output voltage at the second node is pulled above the nominal termination voltage, the second node being connected to a termination load. The bipolar transistor current source circuit is configured to source current to the second node when the operational amplifier sources current to the first node so that the output voltage at the second node is pulled up as a result of the current sourced by the bipolar transistor current source circuit through the second node to the termination load. The bipolar transistor current sink circuit is configured to sink current from the second node when the operational amplifier sinks current from the first node so that the output voltage at the second node is pulled down as a result of the current sinked by the bipolar transistor current source circuit through the second node from the termination load. Thus, the output voltage at the second node is maintained at the nominal termination voltage.

摘要： A system to detect occupants is provided. The system may rotate the field of views of multiple sensors in order to scan an area. The system may scan the area multiple times. The system may determine the number of occupants in the area based on a comparison of a scan of the area with a scan of the area when the area is determined to be unoccupied. The system may determine the number of occupants in the area based on a maximum number of occupants detected by any of the sensors. The system may also determine a location of an object or an occupant from scans of the area obtained from multiple sensors.

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： A system for auto-commissioning a light fixture may position the light fixture based on sensor data received from at least one sensor. In order to focus the light fixture on a target location, the system may vary the position of the light fixture and determine a position of the light fixture where the light level received by the photosensor reaches a determined light level. The system may adjust a light characteristic of light emitted by the light fixture so that the color of light received by the photosensor at the target location matches a target light characteristic, such as color or intensity. The system may determine a focus position and a light characteristic for multiple target locations. The system may auto-commission multiple light fixtures.

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.
