Title: Fluid flow circuits
Inventor: BAILEY ALFRED JOHN
IPC: F16L55/027
Filed: 1990-06-23
Abstract: A method of providing a fluid flow circuit with a predetermined flow restriction by clamping a restrictor member (14) between co-operating surfaces (11b, 12b) of a union (11, 12) provided in the circuit. The flow restrictor member is provided with one or more orifices (17, 18) whose cross-sectional dimensions are chosen to provide the required flow restriction in the circuit. The flow restrictor member may provide the same flow restriction through the union in both directions or may provide different flow restrictions in each direction by the use, for example, of a valve member (19) which is carried by the restrictor member and is moved axially relative to the orifice or orifices by the flow in one direction through the union to modify the flow through the union in that direction. <IMAGE>

Title: Secure retrieval of data from a stored database
Inventor: ASHMORE ROBERT
IPC: G06F21/62
Filed: 1990-10-17
Abstract: A process is disclosed for retrieving data from a database stored in a fixed disc 3 for display on the screen of a VDU 6 or printing at a printer 9. Fields in each retrieved database record are stored in a RAM 4 in the form of a virtual screen 41 which is similar to a screen layout for the VDU 6 except that physical constraints are not taken into account up to preset large dimensions, in this case 256 rows, each having 256 character locations. Blocks 44 within the virtual screen 41 are selected for display to give the effect of a window or viewport on the virtual screen 41. Versatility in security of data fields is achieved by comparisons between a user security level and a separate security level value for each individual field. According to the comparison, a control unit 2 selects which fields are written to a screen memory 8 or printed and which may be written to in the RAM 4. <IMAGE>

Title: Speech processor using compression and non-linear transfer function
Inventor: TAMURA JUNICHI
IPC: G10L25/93
Filed: 1990-10-18
Abstract: A compression circuit compresses speech information obtained by analyzing the speech in accordance with a non- linear transfer function. A circuit makes compressibility a transfer function coefficient of the compressing circuit corresponding to each of the phonemes or frames constructing the speech, and a memory stores the speech information. The clearness of the consonant part of the input speech may thus be improved and a speech of a high quality can be synthesized. The voice tone of a speech can be changed by merely converting the compressibility. <IMAGE>

Title: Tyre pressure and temperature measurement system
Inventor: SHARPE BRIAN ALLAN JOHN
IPC: G01L19/04
Filed: 1992-01-09
Abstract: Vehicle tyre inflation pressure, e.g. of an aircraft undercarriage tyre, is measured in real time by a sensor assembly 20 mounted on a rotary part of the wheel. The assembly 20 includes a piezoresistive cell 21 exposed to inflation pressure and an electronics module 22 comprising an assembly 29 of three printed circuit boards (PCB) 30, 31, 32. A power signal transmitted from the vehicle to the electronics module via a rotary transformer 36 is conditioned by PCB 32 to provide an energising signal for the cell 21. Pressure and temperature signals output by the cell 21 are received by the PCB 30 and converted to digital form before being applied to address locations in a look-up table of PCB 31 which holds pre-calibrated cell outputs. Data from the look-up table is processed to obtain a temperature corrected real time pressure value which is transmitted to the vehicle. If desired a temperature value may also be transmitted. The pressure sensor uses a resistive bridge 23, and temperature is sensed by the voltage drop across a series resistor carrying the total bridge current. The corrected data values are transmitted in binary form by frequency shift keying. <IMAGE>

Title: Cache system for disk array.
Inventor: OLDFIELD CLIVE SCOTT
IPC: G06F12/08
Filed: 1992-12-22
Abstract: A cache system for staging data between host memory and a disk array comprising a plurality of disk storage devices plus associated controller unit, data being storable across the disks of the array in the form of strides, each stride comprising a multi-sector 'stripe' of data on each of two or more devices of the array and an associated multi-sector parity block on a further array device. The cache system includes means for linking the data and associated parity making up a stride within the cache as a cache data unit which is manipulated in the cache as a single entity. References from the host to data held within the cache causes the referenced cache unit to move to the head of a list of cache units. When a cache unit at the bottom of the list is committed to disk, there is an increased likelihood that most or all the data making up a stride will be in the cache and therefore the number of redundant accesses to the disk needed to generate parity data will be reduced or eliminated. <IMAGE>

Title: Vehicle internal noise reduction system
Inventor: IITAKA HIROSHI
IPC: G10K11/178
Filed: 1993-10-22
Abstract: A fuel injection pulse Ti output from an electronic control unit 2 of an engine 1 is transformed into a voltage value a transforming circuit 5. The voltage value is subjected to a "sum of convolution products" process in an adaptive filter 16 and synthesized into a sound to cancel an engine noise sound therein. The synthesized sound is output through a speaker 10 to a passenger compartment so as to cancel noise originating from the engine. A reduced noise sound is detected as an error signal by a microphone 11. The error signal is input to a LMS circuit 18 where filter coefficients for the adaptive filter 16 are updated based on both the input error signal and the fuel injection pulse Ti. Since a fuel injection pulse Ti produced earlier than a combustion stroke is employed as a primary source for the noise reduction, noise can be predicted before it is produced. Accordingly, this noise reduction system has an excellent response to fluctuations of engine load in a transient vehicle operating condition. <IMAGE>
