Title: Neural network signal processor
Inventor: CASTELAZ PATRICK F
IPC: G06N3/04
Filed: 1989-11-01
Abstract: A neural network signal processor (NSP) (20) that can accept, as input, unprocessed signals (32), such as those directly from a sensor. Consecutive portions of the input waveform arc directed simultaneously to input processing units, or "neurons" (22). Each portion of the input waveform (32) advances through the input neurons (22) until each neuron receives the entire waveform (32). During a training procedure, the NSP 20 receives a training waveform (30) and connective weights, or "synapses" (28) between the neurons are adjusted until a desired output is produced. The NSP (20) is trained (Fig 5) to produce a single response while each portion of the input waveform is received by the input neurons (22). Once trained, when an unknown waveform (32) is received by the NSP (20), it will respond with the desired output when the unknown waveform (32) contains some form of the training waveform (30). The processor may be applied to analysis of radar, sonar, infrared or speech inputs, e.g. for object detectional identification, or to expert systems or natural language processing. <IMAGE>

Filed: 1991-04-10
Abstract: A wear-resistant coating is provided on a base material which includes a nitride of chromium, the nitrogen concentration of the coating being increased from an interface between the base material and the coating continuously towards an outer surface of the coating. The coating is produced by the steps of positioning the base material 1 in a vapor deposition chamber 9; producing chromium vapor in the chamber so that the chromium is deposited to form a coating on the sliding surface of the base material 1, introducing nitrogen into the chamber while the chromium is being deposited so that a nitride of chromium is produced and deposited on the sliding surface of the base material forming at least a part of the coating, the nitrogen concentration in the chamber being continuously increased so that the nitrogen concentration in the coating continuously increases from the interface between the base material and the coating towards the outer surface of the coating. The coating has a layer adjacent to the base material consisting substantially of chromium, whilst the coating may have a layer adjacent to the outer surface consisting substantially of at least one of CrN, Cr2N and a mixture of Cr2N and CrN. The coating may be used as the sliding surface of a piston ring of an internal combustion engine.

Title: Artificial snow fall device
Inventor: SUTHERLAND STUART DEANE
IPC: G09F19/12
Filed: 1991-11-04
Abstract: An artificial snow fall device includes a fan 5 blowing air through a venturi 10 to draw artificial snow particles from a vessel 13 through a venturi input tube 12 and up a venturi output tube 11 for discharge at outlet 26. The particles then fall back into the vessel 13, via the foliage of the christmas tree. The device may be provided with a water reservoir 27 and wick 29 to increase the humidity of the air stream passing to the venturi - this has the effect of reducing the static charges imparted to the artificial snow particles. The outlet 26 includes an adjustable cone for altering the linear air speed at the venturi output to ensure that the snow particles fall within the confines of the collection vessel 13. <IMAGE>

Title: Wide to standard format motion compensated video signal processor
Inventor: KEATING STEPHEN MARK
IPC: H04N7/00
Filed: 1994-02-04
Abstract: The motion vector processor determines motion vectors representative of motion within successive images and is also responsive to a default motion vector representative of motion of the images themselves (pan and scan). Alternatively, or in addition, block matching for determining motion vectors representative of movement within the first images can be responsive to an image offset representing relative movement between a pair of first images to offset one image of the pair by half the offset in a first direction and to offset the other image of the pair by half the offset in the opposite direction. The apparatus enables motion compensation to be performed on moving a letterbox representation of a high resolution image within a normal resolution video image (see fig. 6) and on panning and scanning an edge cropped representation of a high resolution image within a normal resolution video image. <IMAGE>
