Abstract: The invention relates to a management system for the operation of a wind turbine, which regulates the power output of the turbine. The wind turbine comprises a rotor with at least one rotor blade that is positioned at an adjustable angle to the rotor.

Abstract: In a subscriber line accommodation apparatus, subscriber line termination units individually terminate a plurality of subscriber lines. An address information acquisition unit acquires address information of each communication terminal connected to the subscriber line terminated by the subscriber line termination unit.      When the IP address of a communication terminal is designated, and one of an ARP request to acquire a MAC address corresponding to the IP address and an ARP response is done, an address information coincidence determination unit determines whether an address indicating the transmission source of an ARP packet used for the ARP request and the ARP response coincides with one of pieces of address information acquired by the address information acquisition unit. A packet sending control unit permits sending of the ARP packet when it is determined that the addresses coincide. A packet filtering method is also disclosed.

Abstract: Based on utilization information characterizing aspects of contracts entered into by independent agencies with one or more independent service-providers, instances are identified in which first and second different independent agencies have each entered into a contract with a common service-provider. Based on the identified instances, using a portion of the utilization information specifying monetary value of contracts associated with the identified instances, overlap statistics are calculated characterizing a degree, with respect to the monetary value, to which interactions of the first agency and at least one common service-provider overlap with interactions of the second agency and the at least one common service-provider. A graphical representation of the overlap statistics is generated and indicates the degree, with respect to the monetary value, to which interactions of the first agency and the at least one common service-provider overlap with interactions of the second agency and the at least one common service-provider.

Title: Three bladed savonius rotor
Inventor: VANDERHYE ROBERT A
IPC: F03D3/06
Filed: 2005-12-29
Abstract: A Savonius three bladed vertical axis wind turbine rotor has operational characteristics superior to those of conventional three bladed rotors. The blades have high curvature and a high skew factor, for example a curvature of greater than about 7:1 (preferably at least 5.5:1, e. g. 2:1 - 5:1 ), and a skew factor of greater than about .6 (preferably at least .7, e. g. about .75-.9). Preferably the rotor also includes at least one substantially vertical shaft, the blades operatively connected to the shaft. The rotor typically has an aspect ratio of at least about .8:1, preferably at least about 2:1 (with the aspect ratio of each blade about twice that of the rotor). The blades desirably comprise a plurality of substantially aligned spokes axially spaced along the shaft, each spoke comprising three generally radially extending ribs arcuately spaced from each other approximately 120 degrees. The rotor typically has a maximum power coefficient (Cp) of at least about twice that of an otherwise identical rotor with a skew factor of .5 or less. The Savonius rotor may be used in combination with a generator or other driven element, with a drive (which automatically increases the effective gear ratio as the rotational speed of the rotor increases) operatively connecting the generator to the rotor. The rotor may alternatively be connected to a propeller of a multihull wind powered boat.
