Title: A method of finding a physical location of a mobile telephone at a given time
Inventor: DANDO OWEN ROBERT
IPC: H04W64/00
Filed: 2006-08-09
Abstract: A subscriber database stores RF level and timing advance information associated with all mobile telephones on a network. A location parameters database stores location data that associates different physical locations with RF levels/timing advance data that have been measured or inferred for those locations. The subscriber database is then interpreted for the purpose of establishing the location of a specific mobile telephone at a given time by matching the RF level/timing advance data for that specific mobile telephone against the location parameters database. This generates the location of the mobile telephone. The interpretation or querying of the subscriber database only occurs however when there is a request to establish the location of a specific mobile telephone, and not as an automated process applied to all mobile telephones on a network.

Title: Video processing using quincunx sub-sampling
Inventor: DAVIES THOMAS JAMES
IPC: G06T9/00
Filed: 2007-12-24
Abstract: A method of video signal processing, for a picture sequence, comprises: diagonally low pass filtering 1 input video; performing quincunx sub-sampling 2 (i.e. in a shape corresponding to the dots on the five of a die - see Figure 5), and processing the quincunx samples to provide output video which is rectangularly sampled with reduced spatial resolution and increased picture rate. Also independently claimed is an analogous video encoding method, wherein the quincunx sub sampling reduces input sample rates by a factor of two, and quincunx samples are re-ordered so the signal appears as a conventional, rectangularly-sampled signal to a subsequent encoder. Further independent claims relate to: analogous decoding steps, additionally interpolating the quincunx video signal to produce a video signal at original resolution; and an encoder in which quincunx video samples are retained or discarded on an even or odd functional basis, and samples are split 3 into rectangular samples, forming child pictures (Figure 7) for interleaving 5 into a video stream at double the original rate.

Title: A hydraulic forming process for polygonal rifled tube
Inventor: TRENDALL SIMON
IPC: B21D26/02
Filed: 2008-12-31
Abstract: The formation of polygonal rifled tube from a tubular blank (3) in a container (1) having a polygonal rifled bore (2) of the desired form by means of load applied to and causing displacement of fluid (4) filling tubular blank (3). The load applied being of sufficient magnitude to cause plastic deformation of the tubular blank (3) against the polygonal rifled bore (2) of container (1). The walls of container (1) being of sufficient bulk to withstand, without taking permanent set, the load required to cause plastic deformation and attendant autofrettage. Thus tubular blank (3) permanently takes the form of polygonal rifled bore (2). Release of the applied load permits elastic contraction and removal of the newly formed polygonal rifled tube ready for finishing as a barrel, barrel liner or projectile casing.
