Abstract: A turbine for a vertical axis wind turbine generator includes a supporting structure rotating about a central axis; at least one blade, which is elongate in a longitudinal direction, operatively parallel to the central axis and connected to the supporting structure so as to rotate about the central axis along an operating trajectory, in a rotation direction, wherein the blade, has a wing having an aerofoil defining a head and a tail, wherein the head leads the tail in the rotation direction, and includes a deflector having an aerofoil defining a head and a tail, wherein the head leads the tail in the rotation direction, positioned along the operating trajectory with its tail proximal to the head of the wing and oscillating about a tilt axis which is parallel to the longitudinal axis of the blade and passes through the head of the deflector.

Abstract: An energy saving gas discharge lamp, and method of making same, is provided. The gas discharge lamp includes a light-transmissive envelope, and an electrode within the light-transmissive envelope to provide a discharge. A light scattering reflective layer is disposed on an inner surface of the light-transmissive envelope. A phosphor layer is coated on the light scattering reflective layer. A discharge-sustaining gaseous mixture is retained inside the light-transmissive envelope. The discharge-sustaining gaseous mixture includes more than 80% xenon, by volume, at a low pressure.

Abstract: Peer-to-Peer traffic switching that allows gateway traversal is accomplished using a traffic switch that receives packets from each of the nodes, accommodates synchronization flags, as well as sequence numbering and packet acknowledgements. Avoiding a complex and cumbersome registration process allows two peer nodes to communicate with each other while traversing network address translation gateways, and allows for a process that provides a transparent experience to both nodes so that they do not necessarily perceive that they are communicating through a gateway.

Abstract: A lamp having a measurable ultra violet light emission and having thereon a first marking revealing at least the operating characteristics of said lamp and a second marking evidencing a change in characteristics in response to exposure to ultra violet emissions. In a preferred embodiment of the invention a symbol or other indicia is provided on the lamp as the second marking that fades in accordance with the number of hours the lamp is operating, thus providing an indication of the UV output of the lamp.

Abstract: An electrodeless lamp (10a), wherein the lamp comprises a closed-loop, tubular lamp envelope (13) with parallel cylindrical glass tubes (14a 16a) containing an arc generating and sustaining medium, means (20a) in the form of magnetic toroids for energizing the medium; and a reflector coating (22) associated with the envelope (13) and affixed thereto. In a preferred embodiment of the invention the reflector coating (22) is on the internal surface (24) of the envelope and comprises a layer of a reflective m, such as alumina. Alternatively, the reflective coating (22) can be applied to the external surface of the envelope.

Abstract: The present invention relates to a method for handling global challenge authentication registration in a cellular telecommunications network. A Mobile Switching Center (MSC) receives a registration message from a mobile station, and it determines whether it has capabilities for bypassing global challenge authentication. In instances where the MSC has capabilities for bypassing global challenge authentication, it verifies whether a Visitor Location Register (VLR) relating thereto has a record for the mobile station from which the registration message has been received, and if so, it bypasses the global challenge authentication for the mobile station. When the VLR does not have a record for the mobile station from which the registration message has been received, it performs the global challenge authentication.

Abstract: A mounting assembly (10) for an electrodeless 1 amp (100). The mounting assembly (10) comprises a fixture housing (14) having an inner surface (16) and an outer surface (18). The fixture housing is preferably made from aluminum. Spaced-apart heat sinks (20, 21) are affixed to the inner surface (16) of the fixture housing (14). A reflector (22), which is preferably concave, as is the fixture housing, is positioned within the fixture housing (14). The reflector (22) contains two apertures (24, 26) that are aligned with the heat sinks (20, 21). Thermal insulators (28, 29) are positioned in the apertures and surround the heat sinks, thus thermally isolating the reflector from the heat sinks. The lamp (100) is mounted in the fixture housing by attaching brackets (40, 42), which surround the ferrite transformer cores of the lamp, directly to the top surfaces of the heat sinks (20, 21).

Abstract: A compact fluorescent lamp comprises four dual tube segments affixed to a base having a planar surface. Each of the segments extends in a direction away from the planar surface and is arranged in a plan wherein one of the tubes of each of the four dual tube segments is positioned at the corner of a square. This configuration reduces the wasted area in the center of the base and provides a smaller base thus allowing application of the lamp in areas previously not accessible.
