Title: Selection of positioning handover candidates based on angle
Inventor: KINGDON CHRISTOPHER H
IPC: H04W64/00
Filed: 1998-10-28
Granted: 2005-02-08
Abstract: A telecommunications system and method for determining optimal target Base Transceiver Stations (BTSs) to perform positioning handovers and obtain positioning data is disclosed. When a positioning request is received by a Base Station Controller (BSC) serving the Mobile Station (MS) to be positioned, the serving BSC accesses a database within the BSC, which contains a list of cells belonging to candidate target BTSs. Based on this information, and the main antenna direction of the serving BTS, two candidates for positioning handovers are selected from the list such that the angle between the main direction of two adjacent BTSs is nearly equivalent to the angle between the main direction of two additional adjacent BTSs. By selecting the target BTSs in this manner, it can be ensured that the target BTSs surround the MS, thus decreasing the error in the location calculations performed by a Positioning Center (PC).

Title: Fluid spray apparatus and method for smooth surface gypsum fiberboard panels
Inventor: MILLER DAVID PAUL
IPC: B05B1/04
Filed: 2000-05-16
Granted: 2010-08-03
Abstract: An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a fluid spray including a source of pressurized fluid such as a pump or blower, a distribution manifold and a plurality of nozzles to direct the fluid spray at the surface of the slurry. In operation, the fluid spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.

Abstract: The RT regions of an ISB light emitter comprise pre-biased SLs and a multiplicity of split quantum wells (SPQWs). A SPQW is a quantum well that is divided into a multiplicity of sub-wells by a first barrier layer sufficiently thin that the upper and lower energy states are split beyond their natural broadening and contribute to different minibands in each RT region. In contrast, adjacent SPQWs are coupled to one another by second barrier layers. The thicknesses of the latter layers are chosen so that minibands are created across each RT region. In one embodiment, the emitter includes an I/R region between adjacent RT regions, and in another embodiment the I/R  regions are omitted.

For this purpose, the frequency of appearances of a plurality of characteristic words and phrases in a document satisfying each analysis condition i.s calculated. As a result, multiple cooccurrence words and phrases and component-cooccurrence words and phrases are discriminatively displayed. It is therefore possible for the user to appropriately analyse the contents of a plurality of documents.
