Title: Manufacture of a filtering screen
Inventor: HUGHES ANDREW
IPC: B01D29/01
Filed: 2002-11-12
Granted: 2010-01-26
Abstract: A method of manufacturing a filtering screen in which a frame of plastics coated metal or reinforced plastics material is located in a jig and at least one sheet of wire cloth is placed over the frame and its edges are gripped by pneumatically operated clamps carried by the jig. The clamps are pneumatically driven outwardly of the frame to tension the cloth in orthogonal directions. The tensioned cloth is pressed against the frame and heated in order to bond the cloth to the frame. The heated material is allowed to cool, and after completion of the bonding step the clamps are released, allowing the frame to be removed from the jig. Where necessary the cloth is trimmed back to the edges of the frame. Two or more layers of wire cloth are bonded to the frame, one above the other, and typically the cloth in contact with the frame is of coarser mesh then the cloth or cloths above it. Apparatus is described comprising a jig adapted to receive and locate the frame, pneumatically operated clamps carried by the jig are adapted in use to grip the edges of a layer of wire cloth placed over the frame and pneumatically driven tensioning means, on the jig, drives the clamps outwardly from the frame to tension the cloth in orthogonal directions. A heated platen is employed to press the cloth against the frame in order to heat and locally melt the plastics material and cause the wires of the cloth to become embedded in ridges in the upper surface of the frame. Drive means effects relative movement between platen and jig to bring the platen into contact with the wirecloth and after heating and bonding has occurred to retract the platen and/or jig so as to remove the source of heat to allow the frame and cloth to cool, to complete the bonding of the cloth to the frame. A separate set of pneumatically operated clamps is provided for gripping all four edges of each wire cloth layer to allow each layer to be individually tensioned. Typically the jig is adapted to receive two frames side by side and the wirecloths are large enough to cover both frames, and after bonding the covered frames are separated by cutting the wirecloth spanning the junction between the two frames.

Title: Method and system for calibrating location systems
Inventor: HOLT BRIAN
IPC: G01S5/00
Filed: 2002-06-20
Granted: 2008-12-16
Abstract: This invention relates to a method for calibrating a wireless location syste m (WLS) to enable the system to make highly accurate differential measurements such as time difference of arrival (TDOA) and frequency difference of arriva l (FDOA). Calibration is accomplished by transmitting a signal from an unknown location and measuring at each of two receivers (75, 76) the parameter to be calibrated from that part of the received signal reflected or refracted from an object at a known location in the area. A differential measurement error is determined by comparing the expected difference in the parameter measurement s with the actual difference in the parameter measurements. The expected difference is known, a priori, based on the locations of the receivers and t he location of the object.

Granted: 2009-05-26
Abstract: A method and system for providing alternative prepaid service when a serving Packet Data Service Node (PDSN) does not support prepaid or at least the type of prepaid the user has subscribed to. The serving PDSN sends an access request to a Home Authorization, Authentication & Accounting Prepaid Server (HAAA/PPS) with an indication of its capability to support prepaid service and to terminate sessions based on requests from remote nodes. When the serving PDSN is neither capable of prepaid service, nor does it support session termination by a remote node, the HAAA/PPS determines that a prepaid session is allowed and supported in combination with a Home Agent (HA) for duration-based prepaid service. When the PDSN is not prepaid capable but supports session termination capability, the HAAA/PPS determines that any type of prepaid service can be allowed and supported by the HAAA/PPS in combination with the HA.
