| 20090021079 | Power Systems and Methods Using an Uninterruptible Power Supply to Transition to Generator-Powered Operation - A loss of a power source for a bus is detected. Responsive to detecting the loss of the power source, a voltage is generated on the bus using an uninterruptible power supply (UPS). A generator is transitioned to a desired output state concurrent with generating the voltage on the bus using the UPS. The generator is coupled to the bus responsive to the generator attaining the desired output state. The UPS may be used to provide power to a load connected to the bus while the generator is in transition. For example, detecting the loss of the power source may be preceded by operating a converter of the UPS coupled to the bus as a rectifier and generating the voltage on the bus using the UPS may include operating the converter of the UPS as an inverter. | 01-22-2009 |

| 20100141039 | HIGH AVAILABILITY, HIGH EFFICIENCY DATA CENTER ELECTRICAL DISTRIBUTION - Unlike symmetric power feeds for dual-corded server environments, an asymmetrical power system for high availability environments uses an imbalanced power feed system, allowing lower cost implementation and, in some cases, reduced energy loss in the primary power supply path.
