|20140211363||METHODS AND APPARATUS FOR IMPROVED LATCHING RELAY DRIVER - 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.||07-31-2014|
|20130191658||METHODS OF ACHIEVING COGNIZANT POWER MANAGEMENT - A system and method of increasing the efficiency of overall power utilization in data centers by integrating a power management approach based on a comprehensive, dynamic model of the data center created with integrated environmental and computational power monitoring to correlate power usage with different configurations of business services utilization, with the techniques of CPU level power management.||07-25-2013|
|20130147570||METHODS AND APPARATUS FOR LOAD INTERROGATION USING POWER USAGE MODULATION - Methods and apparatus provide for: detecting an identification (ID) number associated with a piece of information technology (IT) equipment using a first computer-readable and executable program running on the piece of IT equipment; modulating a power usage of the piece of IT equipment as a function of the ID number using the first program running on the piece of IT equipment; monitoring the power usage of the piece of IT equipment using a power distribution unit (PDU) that provides operating power to the piece of IT equipment; and detecting modulation in the power usage of the piece of IT equipment caused by the first program running on the piece of IT equipment, such detection being performed using a second computer-readable and executable program running on the PDU.||06-13-2013|
|20120173911||METHOD AND SYSTEM FOR DETECTING WHETHER A COMPUTER SERVER HAS SHUT DOWN GRACEFULLY - 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.||07-05-2012|
|20120173779||Local Port Browser Interface - The present invention relates to KVM switches that contain both remote and local ports and provide a user of the local port with a similar WEB based interface experience as that experienced by the remote user.||07-05-2012|
|20120166693||Intelligent Asset Management System - A system and method of associating the identification of a server with its physical location thorough the use of an asset management strip and asset management tags. The asset management strip is extendable by means of slave asset management strips. The asset tags are attached to data center components, such as servers, in racks. They are removably attached to the asset strip and provide identification information to the asset strip. The asset strip can correlate the identification information with the location where the tag attaches to the strip. The strip provides the rack identity to management software over a network, which includes an indication of a vertical location on the rack of the component and the component identification data.||06-28-2012|
|20120146655||METHODS AND APPARATUS FOR SENSING GROUND LEAKAGE AND AUTOMATED SELF TESTING THEREOF - 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.||06-14-2012|
|20120106021||Methods And Apparatus For Improved Relay Control - 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.||05-03-2012|
|20120086425||METHODS AND APPARATUS FOR RESISTIVE VOLTAGE SENSING IN AN ISOLATED POWER DISTRIBUTION UNIT - 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.||04-12-2012|
|20120030347||System and Method for the Application of Psychrometric Charts to Data Centers - 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.||02-02-2012|
