Abstract: A power supply system for use with electronic gaming tables in a casino is disclosed. Each gaming table is associated with a unique iPDU and is viewed by one or more video cameras. When an electronic device in a table fails or is taken offline, regulatory personnel can review the video record that corresponds to the duration of the failure or offline status to determine whether the dealer or a bettor has caused the failure or offline status to come about.

Abstract: Methods and apparatus provide for: at least one electromechanical relay including a coil and at least one pair of contacts, the contacts transitioning between a de-energized state and an energized state in response to current through the coil; a microcontroller having at least one tri-state output operating to produce ON, OFF, and FLOAT states; and a driver circuit operating, in conjunction with the tri-state output of the microcontroller, to control the current through the coil of the relay such that: (i) a transition of the tri-state output from OFF to FLOAT maintains the contacts of the relay in their de-energized state through the transition, and (ii) a transition of the tri-state output from ON to FLOAT maintains the contacts of the relay in their energized state through the transition.

Abstract: A system and method of displaying the temperature and relative humidity data of sensors on a psychrometric chart. The system and method operate to display an environmental envelope on the psychrometric chart in order to compare the data of the sensors to the environmental envelope of the psychrometric chart, in order to ensure safe operating conditions for data center equipment.

Abstract: Methods and apparatus provide for a primary side circuit including one or more voltage nodes; and a monitoring circuit operating to monitor one or more parameters of the primary side circuit, and including at least one sensing circuit and at least one processing circuit within a secondary side circuit, where the sensing circuit includes a resistor network having an input for receiving a first sensed voltage from a first of the voltage nodes of the primary side circuit, traversing an isolation boundary between the primary side circuit and the secondary side circuit while adhering to a safety specification, which includes a primary-secondary isolation requirement, and having an output for providing a first modified sensed voltage to the processing circuit.

Abstract: In an energy management system for a data center, intelligent power distribution units are synchronized by a time server. Measurements carried out by the intelligent power distribution units are commenced and stopped synchronously. Each intelligent power distribution unit carries out a calculation based upon the Unix Epoch Time of receipt of a sampling command from the energy management system.

Abstract: Methods and apparatus provide for: measuring leakage current from a source of AC power, which provides power to at least one load circuit; and comparing the measured leakage current values against one or more predetermined thresholds to establish status therefor; and automatically performing self tests to determine whether the leakage current sensing and comparing operations are operative.

Abstract: Methods and apparatus provide for at least one relay with contacts transitioning from: an OFF state to an ON state in response to an ON-pulse of current through a coil in a first direction; and the ON state to the OFF state in response to an OFF-pulse of current through the coil in a second, opposite direction. A driver circuit operates to produce the ON-pulse through the coil of the relay in response to a control signal commanding the ON-state of the contacts; produce the OFF-pulse of current through the coil of the relay in response to a control signal commanding the OFF-state of the contacts; and produce the OFF-pulse of current through the coil of the relay in response to a loss of operating potential across the pair of operating power nodes.

Abstract: A server in a data center is supplied with power by a power distribution unit (“PDU”) having outlet-level power monitoring and switching capability. A predetermined server-specific time after a shutdown command has been issued to the server, the level of power consumption of the server is compared with a predetermined server-specific level of power consumption. If the level of power consumption of the server at that time is less than the server-specific level of power consumption, the server is considered to have been gracefully shut down and power to the server is switched off by delivering an appropriate command to the PDU. If the level of power consumption of the server at that time is not less than the server-specific level of consumption, this indicates a malfunction and power to the server is maintained so the cause can be determined and remedied without unnecessarily corrupting data or damaging the server.

Abstract: A method for improving video quality of a video stream. The method decodes the video stream and generates subblocks of video data from the video stream. The method then removes effects of subblock boundaries from previous deblocking. Each subblock is then smoothed to create pixel values and optionally, subblocks are merged if a predetermined quality is not achieved from the smoothing analysis. The pixels values are filled into each pixel position in the subblock. The subblocks are deblocked and then at least one subblock is outputted to a rendering device.

Abstract: A system and method for providing automatic or semi-automatic identity association between an outlet of an intelligent power distribution unit and a target device, such as a computer server, which is powered by that outlet. The association is accomplished by enabling identification information to be transmitted between a memory device near or within the target device and the intelligent power distribution unit via a power cable. The power cable may include a specialized interface for mating with the power distribution unit and/or providing the identification information.

Abstract: A method for environmentally cognizant power management that gathers server, application and environmental information from different devices to compute an aggregate behavior model.

Abstract: An association between a system's in-band identification credentials with out-of-band identification credentials may arise by making a universal serial bus device emulation in the form of either a virtual mass storage device or a virtual network adaptor. In the case of the former, a machine readable name is decoded to determine which KVM port a target device is connected to. Such can be used to associate a system's known in-band identification credentials with decoded out-of-band identification credentials from the virtual mass storage device. In the case of the latter, the target may be searched and queried through an out-of-band path to ascertain in-band identification credentials.
