Abstract: A highly flexible base station architecture provides extremely flexible sectorization and capacity expansion capabilities. A base transceiver station (BTS) appliance can be interfaced with similar modules to form a higher capacity, sectorized configuration. Each BTS appliance can function as a standalone cell. In addition, multiple BTS appliances can be connected together to create a multi-sector base station in which the BTS appliances share baseband data, facilitating softer handoff. A backhaul interface module concentrates the backhaul and supports distribution and routing of packets from the network to co-located BTS appliances.

Abstract: The apparatus relates to a jet pump or apparatus which displaces a main fluid by a pressurized driving liquid. The apparatus has a duct to receive the main fluid, and a driving liquid manifold cooperating with the duct to receive the pressurized driving liquid. First and second sets of inwardly facing jet nozzles are disposed adjacent a transverse plane of the duct and penetrate the duct side walll to pass the driving liquid into the duct at a mixing portion of the duct having a constant cross-sectional area. The first and second sets of jet nozzles are inclined at angles to the duct axis so that the first nozzles are inclined at a greater angle than the second nozzles. Efficiency of the pump is improved by admitting pressurized gas into the duct and providing the pump with a diverging outlet portion to act as diffuser.

Abstract: A push and rocker action switch includes a pair of switchable contacts, either of which is switchable in response to a rocker motion of a depressible actuating member, and both of which are switchable at the same time in response to an overall push depression of the actuating member. The actuating member is positioned by an opening defined in a faceplate such that it is centrally supported by a resiliently yieldable pivot. The pivot and the switchable contacts are provided by raised portions in an elastomeric sheet material which is supported by a circuit board fastened to an underside of the faceplate.
