A large-scale, capacitor-based electrical energy storage and distribution system capable of effectuating load-leveling during periods of peak demand on a utility, and of effectuating a cost savings associated with the purchase of electrical energy. A capacitor or multitude of capacitors may be charged with electrical energy produced by the utility, such as during periods of low demand or low cost, and discharged during periods of high electrical energy consumption or high electrical energy cost. One or more capacitors may be located at a consumer's residence or business. Alternatively, a farm of capacitors may be provided at or near a utility, or at or near a location experiencing high demand. In another embodiment, one or more capacitors may be located in or on a vehicle, such as an automobile, a truck, or a train of a light rail system.

Consumer, merchant, and transactional data from a closed loop network and external sources may be leveraged to increase demand of a merchant's inventory during normally low-demand periods. Extensive data mining is used to determine the excess merchant inventory and demand patterns at different times and different locations for merchants and groups of merchants. Similar data mining is used to analyze cardmember demand patterns to identify the cardmember preferences regarding when and where they which to purchase goods and/or services. Cardmembers may also be grouped based on their demand patterns. Using pricing as a lever, cardholders with specific preferences are targeted to shift the demand from peak periods and locations to non-peak periods and locations, and to increase the non-peak demand by location as well as time period. Higher precision may be obtained using product level transaction data from point-of-sale terminals used by merchants wherever applicable.

A gas turbine engine fuel supply system includes a primary gear pump, a secondary gear pump, and a pump bypass valve. The primary gear pump always actively delivers fuel to the downstream fuel system, and is sized to supply 100% of the burn flow needed at a select low demand condition. The secondary gear pump is sized to make up the remainder of the flow at high demand conditions, and actively delivers fuel to the downstream fuel system only during those conditions. To supply discharge fuel pressures in excess of gear pump capability, a supercharger pump is disposed upstream of the primary and secondary gear pumps. The pump bypass valve is configured to regulate fuel pressure at the primary gear pump outlet to one of a plurality of preset differential pressures above one of a plurality of fuel load pressures and prevents reverse pressurization of the gear pumps.

The invention relates to an energy storing method and apparatus for use by end-users of energy, such as commercial property owners and operators. The system differs from past systems, insofar as it is not intended to be used by and in connection with energy suppliers, such as large utility and power supply plants and grids. The system preferably relates to the manner in which an end-user of energy can implement energy and costs savings, by using energy storage and time-shifting methods, to control and regulate the consumption of energy in a manner that achieves a cost savings over a period of time. One aspect of the method relates to accurately forecasting and predicting the energy demands and peaks that might occur on a daily basis, by recording and analyzing the prior day's history, as well as the overall energy demand histories, using short and long term forecasts, and then setting up a variable energy storage/use plan or schedule that helps to reduce the peak demands by time-shifting the energy that is used, i.e., reducing consumption during high demand/high cost periods, and using the energy stored during low demand/low cost periods during the high demand/high cost periods.

A method of storing and supplying a gaseous hydrogen product to a pipeline under a product purity specification in which a hydrogen stream made up of gaseous hydrogen is compressed to form a compressed hydrogen stream and introduced into a salt cavern for storage. A crude hydrogen stream, contaminated from storage in the salt cavern is recovered and purified by sufficiently removing at least carbon dioxide and water vapor to produce a hydrogen product stream having an impurity level at or below the product purity specification. The hydrogen product stream is supplied back to the pipeline. Alternatively, during periods of low demand, hydrogen produced by a production facility is both purified and supplied to the pipeline and stored in the salt cavern. During high demand period, both the output of the production facility and hydrogen retrieved from the salt cavern are purified and supplied to the pipeline.

An adaptive contention-aware thread scheduler may place software threads for pairs of application on the same socket of a multi-socket machine for execution in parallel. Initial placements may be based on profile data that characterizes the machine and its behavior when multiple applications execute on the same socket. The profile data may be collected during execution of other applications. It may identify performance counters within the cores of the processor sockets whose values are suitable for use in predicting whether the performance of a pair of applications will suffer when they are executed together on the same socket (e.g., values indicative of their demands for particular shared resources). During execution, the scheduler may examine the performance counters (or performance metrics derived therefrom) and determine different placement decisions (e.g., placing an application with high demand for resources of one type together with an application with low demand for those resources).

The invention comprises: storing high accurate model in the romance server; the three-dimensional browser of client terminal only provides large simple coarse model; user can zoom, move, and rotate said model at the client model to select best sight point; when user stops the operation, the client terminal sends a romance request to the server while said request contains the information as present sight point, direction and illumination condition; the server according to the request of client terminal processes the romance and returns the photo of high accurate model. Since the sensitive high accurate model is stored in the client terminal, the invention has safety advantage; since the client terminal and the server exchange the photo whose average size is 30KB only when the user stops the operation, the invention has lower demand for network; and the client terminal only romance simple model without needing high graphic property.
