Patent number: 10067523Abstract: A data center energy management (DCEM) server configures a power supply in the data center. The DCEM server sums input alternating current (AC) power of the power supply to a total AC power of the data center, wherein the total AC power of the data center is a sum of AC power of a plurality of power supplies. The DCEM server sums output direct current (DC) power of the power supply to a total DC power of the data center and reports a ratio of total AC power to total DC power as data center power conversion efficiency. The DCEM server sets a preset power supply efficiency threshold. The DCEM server determines that a real-time power efficiency level is below the power supply efficiency threshold. The DCEM server, responsive to a determination that real-time power efficiency level is below the power supply efficiency threshold, may remedy the power supply.Type: GrantFiled: February 7, 2014Date of Patent: September 4, 2018Assignee: International Business Machines CorporationInventors: Wael R.

Patent number: 9135577Abstract: A mechanism is provided for statistical determination of power circuit connectivity based on signal detection in a circuit. Signal data from the circuit gathered and a determination is made as to whether a signal of interest is present in the gathered signal data from the circuit using a statistical analysis of the gathered signal data. The statistical analysis comprises using a mean current value and statistical deviation of the current value of the signal data over a predetermined period of time to compute a confidence range. The confidence range is compared to a first threshold and a second threshold. A determination is made that the signal is present in response to the confidence range being above the first threshold. A determination is made that the signal is not present in response to the confidence range being below the second threshold.Type: GrantFiled: October 10, 2012Date of Patent: September 15, 2015Assignee: International Business Machines CorporationInventors: Wael R.

Patent number: 8519843Abstract: A communications system is provided for direct communications between powered elements. A controller hub injects a first message via a modulated communication signal onto a branch circuit using a hub-side power line communication (PLC) coupler. An element-side PLC coupler associated with a powered element in a set of powered elements detects the first message and sends an interrupt to a mini-controller in the powered element. The mini-controller receives the interrupt from the element-side PLC coupler, extracts the first message using the element-side PLC coupler; reads a destination identifier in the first message; compares the destination identifier in the first message to a mini-controller identifier in the mini-controller; sends an acknowledgement message back to the controller hub in response to the destination identifier in the first message matching the mini-controller identifier, and forwards the first message to the powered element.Type: GrantFiled: January 27, 2011Date of Patent: August 27, 2013Assignee: International Business Machines CorporationInventors: Wael R.
