| 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 |
