Title: Missile guidance using hot point detection
IPC: G01S3/789
Filed: 1980-11-05
Abstract: A missile M is equipped with a rearwards facing tracer hot point TR having a temperature of 1500 DEG K. To detect the tracer for automatic guidance over the whole flight path and against a background scene generally at a temperature of 300 DEG K, the radiation collected by scanning 6 is confined to a band of relatively long wavelengths over which the scene radiance is substantially constant but over which the tracer radiance is a decreasing function of increasing wavelength. The collected radiation is divided into two adjacent sub-bands by a filter system 20 and fed to two separate detectors 5, 25. A difference 2 in detector outputs exceeding preset threshold 36 indicates the presence of the tracer. The position of this difference signal in the scanning raster is fed (15) to the missile control system for automatic guidance onto the centre of the scanned field which centre has been aligned with the target C. <IMAGE>

Title: A channel plate electron multiplier structure having a large input multiplying area
IPC: H01J43/22
Filed: 1980-12-19
Abstract: A channel plate electron multiplier structure suitable for use in a photomultiplier tube comprises a plurality of discrete, apertured dynodes arranged as a stack with the apertures (16) in each dynode aligned with apertures in an adjacent dynode to provide channels. The apertures in the input dynode (12) diverge in the direction of incoming electrons to an extent that substantially the entire surface area of the input side constitutes the multiplying area. By enlarging the multiplying area of the input dynode then the majority of the electrons produced by the photocathode (30) of a photomultiplier tube (24) can be captured irrespective of their angle of incidence. If desired a grid (20) may be arranged adjacent to, but spaced from, the input dynode (12). The grid (20) in use is held at a negative voltage relative to the input dynode (12) to provide a field which directs electrons from the multiplying area towards the apertures therein. <IMAGE>

Title: Locking device
Inventor: FAGG WILLIAM THOMAS
IPC: B60D1/60
Filed: 1981-09-18
Abstract: A locking device (6) for preventing unauthorised use of a towing hitch socket comprises a member (7) having a spherical part and a wedge-shaped part (8) which together substantially fill the socket which is to be locked. The spherical part has a bore (10) into which a barrel lock (9) is fitted so that the lock can be operated by a key inserted into a keyhole (23) from beneath the device. Operation of the barrel lock causes rotation of a disc (15) which is a running fit in the bore (10). Rotation of the disc causes a slide (20) to move along a transverse bore (21) between an "unlocked" position in which the slide is completely within the bore and a "locked" position in which it protrudes from the member (7) and engages in a recess in the socket. The disc (15) acting between the barrel lock and the slide prevents shearing of the relatively weak operating pin of the barrel lock in the event of force being applied to the slide in an attempt to break open the locking device. <IMAGE>

Title: Continous word string recognition
Inventor: MOSHIER STEPHEN LLOYD
IPC: G10L15/10
Filed: 1982-09-21
Abstract: A speech recognition method and apparatus for recognizing word strings in a continuous audio signal are disclosed. The word strings are made up of a plurality of elements, and each element, generally a word, is represented by an element template defined by a plurality of target patterns. Each target pattern is represented by a plurality of statistics describing the expected behavior of a group of spectra selected from plural short-term spectra generated by processing of the incoming audio. Each target pattern has associated therewith at least one required dwell time position and at least one optional dwell time position. The number of required dwell time positions and the sum of the required and optional dwell time positions define, in effect, the limits of a time interval during which a given target pattern can be said to match an incoming sequence of frame patterns. The incoming audio spectra are processed to enhance the separation between the spectral pattern classes during later analysis. The processed audio spectra are grouped into multi-frame spectral patterns and are compared, using likelihood statistics, with the target patterns of the element templates. Each multi-frame pattern input, which inputs occur at a frame rate which requires each keyword target pattern to correspond to at least two of the multi-frame patterns, is forced to contribute to each of a plurality of pattern scores as represented by the element templates. The contributions of said multi-frame pattern inputs to said pattern scores is controlled, in part, by said required and optional dwell time constraints. A concatenation technique is employed, using dynamic programming techniques, to determine the correct identity of the word string.
