Patent GB-2253500-A (GB)
Title: Object oriented-data bases
Inventor: CONTI PAUL U
IPC: G06F17/30
Filed: 1991-08-16
Abstract: A technique for creating and manipulating objects in a relational data base which responds to command call routines at a relational data base language level. A data base schema generation program is developed at a host program language level using abstract commands therefor. Such program language level commands are preprocessed to encode them into expanded command call routines at the program language level. Such program level command call routines are automatically converted into command call routines at the relational data base language level for use in creating and manipulating objects in the relational data base. <IMAGE>

Title: Web splitting and winding
Inventor: MCKENNA THOMAS G
IPC: B41J15/04
Filed: 1991-09-16
Abstract: Web handling apparatus includes a printer 11 for printing labels L on a web including a plurality of longitudinally extending web portions W1, W2, W3 connected at longitudinal lines 14, 15 of weakening between adjacent pairs of web portions. A guide structure 29, 30 causes adjacent web portions to move along different paths or planes to effect tearing and resultant separation of the web portions at each line of weakening. A rewinder 12 draws on the separated web portions and winds them into separate rolls. In the event tearing does not occur readily along the lines of weakening, knives may be used to assist in separating the web portions. <IMAGE>

Title: Channel coding for speech
Inventor: BOYD IVAN
IPC: H03M13/35
Filed: 1992-01-14
Abstract: Speech is analysed (202) on a frame-by-frame basis to produce LPC coefficients L and excitation information E1 E2. This information is converted (204) into a serial sequence prior to convolutional coding (205). The serial sequence is modified by the addition of trailing zeros (tailing bits) and also by the insertion of one or more further intermediate groups of zeros at an intermediate position in the modified sequence. A further modification to the apparatus involves the use of a systematic code in the convolutional coder (104), wherein the additional inserted groups are not transmitted in the coded sequence, but are re-inserted at the decoder. <IMAGE>

Title: Detecting scene changes
Inventor: HILL PHILIP NICHOLAS CUTHBERTS
IPC: G11B20/10
Filed: 1993-03-26
Abstract: Scene changes in a video sequence are detected by generating data representing the amount of information present in each video frame. This information is processed in such a way that significant changes in the information content are identified as positions where scene changes are likely to occur. The amount of information present in each video frame is determined by compressing the video in accordance with a spatial algorithm, such as JPEG. Under such compression techniques, the amount of data present after compression will vary, depending upon the amount of information present in the original scenes. Thus, for each frame, information is available identifying the amount of data present in the compressed video. This information is analysed on a frame-by-frame basis, providing information identifying the presence of scene changes. In a facility for editing the video, or editing audio for synchronisation against a video track, the scene change information may be displayed to an operator. In a security system, the occurence of a scene change may be identified as an intruder entering an area observed by a camera. On detecting an intruder in this way, various measures may be taken, such as activating a video tape recorder. <IMAGE>

Title: Electrically operated power steering system
Inventor: SHIMIZU YASUO
IPC: B62D5/04
Filed: 1994-12-06
Abstract: The system has a steering torque sensor 12, a steering rotational speed sensor 13 and preferably a vehicle speed sensor 14. The signal sent to the motor driver circuit 16 is based on a torque control quantity DT but is modified by the outputs from sensors 13 or 14 depending on whether the steering is in a turning or returning state St which is detected by sensor 17. For example, a rotational speed control quantity DN may be subtracted from DT when St is positive or added if St is negative. The system gives an optimum assistive steering torque when the vehicle is abruptly steered eg to avoid an obstacle while improving the returning characteristics and steering stability. <IMAGE>

Title: Digital circuit simulation
Inventor: JONES CLIVE RICHARD
IPC: G06F17/50
Filed: 1995-07-13
Abstract: A primary circuit model using a primary simulator operates in conjunction with a plurality of secondary circuit models using a secondary simulator. Only signals external to the secondary circuit models are passed between the primary simulator and the secondary simulator. The primary simulator and the secondary simulator independently increment their simulated time when they are active. The secondary simulator is invoked when a signal to which one of the secondary circuit models is responsive is changed by the primary simulator. The secondary simulator is not exited until no further signal changes are being driven by the secondary circuit models at which stage the last asserted values of signals changed by the secondary circuit models are returned to the primary model. If there are pending signal changes within the secondary simulation when it is entered in response to a signal from the primary simulator, then that primary simulator signal is buffered until those pending signal changes have taken place.

Abstract: A filter housing in the form of a centrifugal concentrator filter unit (3) is dimensioned to be fully containable in a conventional centrifuge tube (2) when sealed with a cap (4) to provide a closed system centrifugal concentrator adapted to concentrate solution without creating external aerosol or fluid contamination. In accordance with a principle aspect of the invention the filter housing (3) comprises two mating parts (5, 6) which retain a filter element (7) between confronting formations of the two parts (5, 6). End wall formations of the two housing parts (5, 6) cooperate to define a capillary channel (16) into which a watery free-flowing cyanoacrylate polymer adhesive or sealant can be introduced from ledge (12A) through aperture (12). The adhesive will flow around the channel (16) by capillary action to form a bead seal (19) between the filter element (7) and the two parts (5, 6). The principle aspect of the invention is applicable to two part filter housings generally. Conveniently and in accordance with other aspects of the invention, a first one of the two parts is provided by a generally cylindrical filter tube (5) which is a loose or sliding fit in the centrifuge tube (2) and which provides a filter reservoir between an open end of the filter tube and the filter element in the form of permeable filter membrane (7) disposed across an opening at or near the other end of the tube, and the second housing part is provided by elongate spacer member (6) extending from the filter tube oppositely to the reservoir which in use abuts a closed end portion of the centrifuge tube (2) to Space the filter membrane (7) therefrom and to define a filtrate collection vessel of a predetermined volume at the closed end of the centrifuge tube (2). <IMAGE>
