Title: Carrier recovery in a digital radio link between a fixed and a mobile radio     unit
Inventor: HULBERT ANTHONY PETER
IPC: H04L25/03
Filed: 1993-03-10
Abstract: In a radio receiver, a Wiener filter can be applied to give optimum estimates of the complex fading signal characteristic from noisy measurements. It relies on knowledge of the noise level and the auto correlation characteristics of the fading signal. Ideally a different Wiener filter should be used for every different fading characteristic which, for a mobile radio link, depends primarily on the speed of the mobile unit. The present invention provides a set of Wiener filters which are used over a range of speeds combined with a method of selecting the best filter to use in any given case without the knowledge of vehicle speed. <IMAGE>

Title: Vehicle anti-theft device
Inventor: UDO HIROSHI
IPC: B60R25/24
Filed: 1995-06-09
Abstract: The anti-theft device for an engine-driven vehicle has a control unit (ECU)2 for controlling the supply of fuel to an engine and/or the ignition timing, and a back-up mechanism 22,23 acting for the control unit 2 when the control unit is damaged. It is determined whether or not the control unit 2 has functioned appropriately when the engine is started up, and if it is determined that it has not, the function of the back-up mechanism 22, 23 is prohibited. (Alternatively, presence of a starter switch signal may cause prohibition). Hence, the engine will not start and theft of the vehicle is prevented even if, for example, the control unit is deliberately damaged and an attempt is made to start the engine. However, the back-up mechanism does function if the control unit develops a fault while the vehicle is running, and the vehicle therefore continues to run. <IMAGE>

Title: Windscreen with directly-extruded peripheral polymeric profile
Inventor: WALKER RODERICK JAMES
IPC: B29C48/12
Filed: 1996-06-14
Abstract: A method and apparatus for extrusion of a polymeric profile on a shaped glass pane each involve use of a mechanism arranged to deposit the profile in a configuration which is pre-programmed in free space and independent of the exact configuration of the pane. In a preferred embodiment, a vehicle windscreen glass 1 is resiliently mounted for movement in a direction normal to the general plane of the windscreen with its periphery biased towards the extrusion nozzle 8 so that the nozzle applies a positive pressure on the periphery opposing said biasing as the profile is applied to the peripheral margin of the glass. The configuration of the resulting profile has a projection on a plane independent of the exact configuration of the pane so that, applied to a vehicle window, the profile may correspond precisely to the required plan despite variations of the shape of the windscreen glass within allowed tolerances.

Title: Radar velocity measurement
Inventor: MOLYNEUX-BERRY ROBERT BEWES
IPC: G01S13/534
Filed: 1996-12-10
Abstract: Radar apparatus stores returns. To determine the approach velocity of a target the target is first classified as a "target of interest" by a thresholding process applied to successive signals to identify potential targets. Doppler processing is then applied only to a selected portion of stored data relating to the target of interest. This invention enables existing moving target indicator MTI radars (1) to be upgraded to give full Doppler capability without the excessive processing capacity required by conventional Doppler radars.
