| 20080215727 | REMOTE MONITORING SYSTEM - A method for monitoring and reporting information regarding status of a power supply/management device operated by a user comprises detecting the status of the device using a monitoring device having an application interface configured to communicate over a communication network, generating a status update indication using a self-describing computer language and sending the status update indication over the communication network to a remote computer, and associating the user with the status update information for the remote device using the remote computer. | 09-04-2008 |
| 20080202599 | FUEL LEVEL MEASUREMENT AND RUN TIME INTERPOLATION - At least one aspect of the invention provides an improved fuel sensing system for a generator, in addition, one or more other aspects of the invention provide improved systems and methods for determining remaining run-time of a generator system. | 08-28-2008 |
| 20080198549 | COOLING SYSTEM AND METHOD - A system for cooling a data center includes a plurality of cooling racks, with each cooling rack including a housing and cooling system components supported by the housing. The system further includes a fluid communication system coupled to the cooling system components of the plurality of racks. The fluid communication system is configured to provide chilled coolant to and exhaust heated coolant from coolant system components of each cooling rack. The system also includes at least one controller coupled to each cooling rack of the plurality of cooling racks to control the operation of each cooling rack. The plurality of cooling racks and the fluid communication system are configured to be modular to allow placement of cooling racks in different locations in a row of equipment racks within the data center. Methods of cooling a data center are further disclosed. | 08-21-2008 |
