Patent GB-2201784-A (GB)
Title: Measuring dimension of articles on a conveyor system
Inventor: LOH PETER
IPC: G01B11/04
Filed: 1987-02-28
Abstract: A dimensional measurement piece of equipment consisting of sensors positioned about the conveyor system providing electrical input signals to a computer by means of an Input/Output Interface. For width/height measurement an Encoder is used as one of the sensors to provide pulse signals. For length the various time intervals are measured and recorded to enable simultaneous determination of the true velocity at which products are travelling and the time it takes for the products to pass particular sensors, e.g. A & B. An inclined sensor C permits height measurement. For width/height, the various pulses and time intervals are measured and recorded to enable simultaneous determination of the number of pulses for the lateral movement of sensors and the time it takes for the products to pass particular sensors. The information is converted to dimensional measurements for continuously up-dated display as Numerical and Graphical Data on a screen monitor. <IMAGE>

Title: Supressing sudden torque load on an engine driving a generator on a vehicle
Inventor: MORI YUICHI
IPC: H02J7/14
Filed: 1991-04-19
Abstract: In a system in which the generator field winding current is controlled in response to comparison of battery voltage with a reference, when the energised electrical loads 3a, 3b, 3c become large the control system would normally respond by causing a sudden rise in the field current resulting in a sudden torque load on the engine. In order to prevent this, a control circuit 10 senses a high electrical load and in response imposes a limited rate of increase in field current. Circuit 10 may sense a high load by detecting that the rate of change of battery, load or generator voltage or of field current is above a predetermined value. The changeover to a limited rate of increase in field current may be inhibited if the engine speed is above idling speed and/or if the battery voltage is low. An embodiment using digital circuitry, (Figs 7 to 10), can impose both a gradual rise and a gradual fall in field current. <IMAGE>

Title: Speech analysis and image synthesis
Inventor: SIMONS ALISON DIANE
IPC: G06T13/20
Filed: 1991-09-11
Abstract: Successive frames of speech (at 1) are analysed 2, 3, 4 to produce a sequence of codewords identifying the character of the frame. A store 6 stores probability values Pei indicating the probability that any codeword was produced by one of a set of standard 'mouth shapes', whilst a second store 7 stores values tij indicating the probability of one mouth shape following another. A Viterbi decoder examines the sequence of codewords and, using the probabilities, estimates the most likely sequence of mouth shapes to correspond to the speech. This can be used to generate a synthetic "talking face" moving image, e.g. for videophone or audio conferencing applications. <IMAGE>
