Abstract: A method, system and computer program product enhance the commercial value of electrical power produced from a wind turbine production facility. Features include the use of a premier power conversion device that provides an alternative source of power for supplementing an output power of the wind turbine generation facility when lull periods for wind speed appear. The invention includes a communications infrastructure and coordination mechanism for establishing a relationship with another power production facility such that when excess electrical power is produced by the wind turbine facility, the excess may be provided to the power grid while the other energy production facility cuts back on its output production by a corresponding amount. A tracking mechanism keeps track of the amount of potential energy that was not expended at the other facility and places this amount in a virtual energy storage account, for the benefit of the wind turbine facility.

Abstract: A method and system enables a packet-switched data communication in a wireless communications system to be quickly and easily reestablished after interruption. The computer communications protocol that has been negotiated during the establishment of the packet-switched data communication may be saved upon interruption and later restored. In an exemplary embodiment, a wireless subscriber activates a call-waiting-type service along with an option to retain a packet-switched data communication. Thereafter, the subscriber may be engaged in a data communication on a packet data channel of the wireless communications system. Acceptance of a subsequent incoming, circuit-switched voice call causes the data packet session to be suspended, but the negotiated parameters of the computer communications protocol are saved. After the subscriber terminates the voice call, another data packet session is established with the saved parameters without needing to renegotiate the computer communications protocol parameters.

Abstract: A method and system for load balancing in ad hoc networks. An ad hoc node stores address information associated with a gateway that provides a communication path between an ad hoc network and another network. When other ad hoc nodes request the address information from the gateway, an ad hoc node through which the request passes may respond by providing the information. This allows responding to requests for address information to be load balanced over the nodes of an ad hoc network.

Abstract: A system, method and computer program product for minimizing risks associated with meteorology dependent activity. Such activity may include operation of renewable power sources and the delivery of power output from those renewable sources for sale on a market. The system and method identify risks to market participants in the event of possible shortfall, and provide metrics and mitigation processes for addressing the risks before the contractual breaches occurs for failure to deliver power, or imbalances occurred in grid operations.

Abstract: The present invention relates to a copper ball insertion machine, for integrating metal inserts in via holes provided through a printed circuit board (PCB), comprising a motor driven X-Y table (2) with the PCB on top. The X-Y table (2) is adjustable to position a selected via hole in a predetermined location aligned with a closable outlet opening (12) of a movable container (6) for metal inserts. The container is by means of a clamping cylinder (28) displaceable for clamping the part of the PCB adjacent said via hole against the working surface (2) of said X-Y table. By means of a pivoting cylinder (20) the container is rotatable for feeding one metal insert through the outlet opening (12) into said via hole. A stamp (30) is drivable by a hammer cylinder (40) for compressing said metal insert to shape and deform it into a tight fit with the via hole.

Abstract: According to the present invention there is provided a body at least partially coated with one or more refractory layers of which at least one layer essentially consist of &agr;Al2O3. Said &agr;Al2O3 layer consists of essentially equiaxed grains with an average grain size of <1 &mgr;m and with a bimodal grain size distribution with coarser grains with an average grainsize in the interval 0.5-1 &mgr;m and finer grains with an average grainsize of <0.5 &mgr;m. The Al2O3 layer further contains striated zones containing titanium (>5 at %) but no nitrogen or carbon. This particular microstructure is obtained by temporarily stopping the gases needed for the growth of the Al2O3 layer and introducing TiCl4.
