Abstract: A customer administrative system of a wireless communications system is interfaced with one or more system database network elements to support single command meta-service activation and management tasks. In this regard, a meta-service comprises a package of individual services. An agent is included in the interface to process single meta-service command for handling by the database network elements. The database network elements supporting the individual services implicated by the meta-service command are identified and are issued appropriately formatted, device specific commands for effectuating the meta-service activation or management task. In the event that each implicated database network element cannot successfully complete the requisite meta-service activation or management task, the service provision state of each implicated database network element is rolled-back to a service provision state prior to receipt of the meta-service command.

Abstract: Subscriber units are tracked in a cellular communications system including a plurality of cells which communicate with subscriber units. A cell type is assigned to each cell according to a mobility characteristic of a subscriber unit population of the cell. Each cell is associated with at least one of a plurality of districts based on the cell type of the cell, such that each of the plurality of districts may be characterized according to a mobility characteristic of a subscriber unit population of the district. A subscriber unit is registered with one of the plurality of the districts according to the mobility of the subscriber unit. According to preferred method aspects of the invention, at least one district is defined for each cell, each district having a geographical extent with respect to the cell location of the cell, to thereby associate each cell with at least one district.

Abstract: The present invention is of a cementitious composition containing OPC, calcined gypsum, a source of amorphous silica and a source of amorphous alumina. The ratio of calcium sulfate hemihydrate to OPC is 0.7:1.0 to 1.4:1.0, the ratio of amorphous silica and amorphous alumina to OPC is 0.26:1.0 to 0.4:1.0, and the ratio of amorphous alumina to amorphous silica is 0.3:1.0 to 1.5:1.0. The cementitious composition, by itself and mixed with aggregates, is fast-setting and exhibits good early compressive strength and very high compressive strength after hydration. Despite the high content of calcium sulfate relative to prior art OPC formulations, the cementitious composition according to the present invention is essentially waterproof and exhibits excellent strength characteristics, even after 2 years under water. The use of calcined gypsum in place of alumina cement or even OPC is of great economic advantage, and in addition, provides the cementitious composition with quick-setting characteristics.

Abstract: The method for de-inking paper pulp produced by the reduction to pulp, with water, of old papers of various qualities according to which a stream of air bubbles (C) is sent through the flow (E2, S2, E3, S3) of pulp at least once, is characterized by the fact that a countercurrent of water (E1) is sent into the stream of de-inking air bubbles after said bubbles have passed through the pulp and become laden with ink particles so that the countercurrent releases the particles (fibers, fines, fillers) borne along by these de-inking bubbles and carries them away.

Abstract: A method and a device is disclosed for the generation of a lens device including a plate of ferroelectric material, the transmission phase gradient of which is be varied over the lens by means of a controllable static electric field. The lens may involve an entire antenna aperture, e.g. a feeder horn or constitute a body covering a slotted wave-guide antenna, be a portion of an antenna aperture or an element in a conventional array aperture. The division of the aperture depends on the number of degrees of freedom to be controlled simultaneously. In a general case N lobes and M nulls are to be controlled at the same time. In the most simple case with N=1 and M=0 the lens should be the entire antenna aperture. The invention is based on the fact that the direction of the wires of the control grids (1, 2) in the lens device must run perpendicular to the direction of the E-field direction of a penetrating high frequency radio wave.

Abstract: A method and system enables a fixed cellular terminal (FCT) to be automatically configured to accommodate landline phones of the country and/or landline network in which it is physically located. The FCT includes a memory and a data structure therein. The data structure includes instructions on how landline phones interface with Public Switched Telephone Networks (PSTNs). Consequently, the FCT may be connected to a landline phone in any country and/or landline network once the FCT is informed of the country and/or landline network in which it is being used. According to one embodiment, a Subscriber Identity Module (SIM), which is needed to activate cellular phones in some systems, is used to inform the FCT of the country and/or landline network.
