Title: Generating shape data for controlled machining
Inventor: SEKINE HIROSHI
IPC: G05B19/4099
Filed: 1995-11-27
Abstract: In a CAD system, after fillet surfaces have been generated for linking curved surfaces of a surface model (step S100), a loint surface is generated between the fillet surfaces (step S114). New fillet surfaces are determined from the fillet surfaces and the joint surface (step S116). Then, a phase relationship is established between data relative to the curved surfaces and data relative to the new fillet surfaces, and this data is combined (step S117) into shape data including data of fillet surfaces which are capable of representing the complete shape of a product, such as a die to be formed by a numerically controlled machine tool. <IMAGE>

Title: Searching a database for titles of records
Inventor: BRENNAN JOHN VIANEY
IPC: G06F17/30
Filed: 1996-10-22
Abstract: A method for searching a computer database for titles of records minimises the number of key strokes to be made for entering characters of the title and comprises initially searching with a search string which comprises the letters of a first part of the title to be searched; e.g. to search for the title "MURPHYS SUPPORTS KNEE MEDIUM", a search string comprising the first characters "MURPHYS S" is entered. A search is carried out and the first title in alphabetical order containing those characters is displayed (Fig 4a), namely, "MURPHYS SUPPORTS FOOT LARGE" with the cursor 10 on the letter "S" of "SUPPORTS". The cursor is transferred to the letter "F" of "FOOT" (Fig 4b) by operating the tab key and the letter "F" is changed to a "K" by entering the letter "K" (Fig 4c). A further search is carried out using the search string "MURPHYS SUPPORTS K" which displays "MURPHYS SUPPORTS KNEE LARGE" (Fig 4d). In similar fashion further searches are carried out (Figs 4e,f) to reveal the title "MURPHYS SUPPORTS KNEE MEDIUM" (Fig 4g).

Title: Continuous interference assessment and avoidance in a mobile radio network
Inventor: MEREDITH SHELDON K
IPC: H04B7/26
Filed: 1998-03-31
Abstract: A mobile radio system includes at least one base site having a system for interconnecting a plurality of radio channel units 203 with a plurality of directional antennas 202. The base site further includes interference avoidance means for controlling communications between each radio channel unit 203 of the base site and mobile radio units communicating with the base site so as to avoid causing potential interference at the operating frequency of each radio channel unit at other base sites. The interference avoidance means monitors for potential interference at the operating frequency of each radio channel unit on each antenna beam. If potential interference exists on an antenna beam determined to be the antenna beam best suited for transmitting and receiving signals at the operating frequency of the radio channel unit, a determination is made as to whether adjacent antenna beams have reduced chance of potential interference and sufficient signal strength for communication. A comparison is made of the signal strength of received signals at the operating frequency of the radio channel unit with one or more threshold values to assess the proximity of the mobile radio unit to the base site, and the transmission signal strength for signals transmitted from the radio channel unit to the mobile radio unit are controlled based on the proximity assessment.

The singulation bed comprises a plurality of side by side and parallel conveyor lanes (5-13) with the lanes being driven at speeds which increase progressively from slowest at one side of the bed to fastest at the other side of the bed. A deflecting rail (14) mounted above the singulation bed (4) and extending thereacross, deflects packs from the slower lanes to the faster lanes and an outlet conveyor (15) mounted by the side of the fastest conveyor lane (13) receives and conveys a single stream of packs from the singulation bed. A return conveyor (16) is mounted by the side of the outlet conveyor at a lower level to receive any packs falling from the outlet conveyor and return them to the supply hopper. A conditioning station may be mounted over the outlet conveyor for regulating the shape of the packs and an orientation checking station may be provided downstream of the conditioning station to remove wrongly oriented packs from the outlet conveyor onto the return conveyor.
Patent GB-2329221-A (GB)
Title: Control scheme for pressure relief
Inventor: KRONE JOHN J
IPC: G05D16/20
Filed: 1998-07-29
Abstract: A control scheme is provided that controls the maximum pressure level in desired locations of a hydraulic system. This control scheme eliminates the need of separate line relief valves that many times create pressure spikes in the hydraulic system. In one example, the control scheme functions to sense the operating pressure at the desired location and compares it to a differential pressure and a desired input command during one step or loop to establish a predicted pressure level. The predicted pressure level is compared to the pressure necessary to initiate movement of the valving element in an electrically actuated control valve mechanism. The result is used to move the valving element to a predetermined position if the predicted pressure level is less than cracking pressure level and the differential pressure is greater than zero. If the predicted pressure level is higher than the cracking pressure level, an output control signal is boosted in order to move the valving element to an open position in a much quicker time period to offset the over pressure condition before a pressure spike occurs.

Patent GB-2345557-A (GB)
Title: Fast trace log for a multi-processing environment
Inventor: HANSEN OLE BRIAN
IPC: G06F11/34
Filed: 1999-01-07
Abstract: Tracing the operation of one or more processes A, B, or threads #1, #n within a single process, in a multi-processing operating system. When instantiated, a Dynamic Link Library (DLL) creates a common buffer 10 within an area memory, into which trace information supplied by the processes is stored, together with standard header information (e.g. timestamps, process and thread ID module number, format number), under control of a tracing function FTLog of the DLL. Every call of the FTLog tracing function is allocated a piece of the common buffer 10 using a single common variable stored at a memory location P. FTLog prevents more than one thread from using the same variable simultaneously, and also flushes the buffer, e.g. to a disk file, if the trace information to be stored would exceed the end of the buffer. Flushing only occurs after all the threads that are currently writing to the buffer, as indicated by a count byte Cnt stored at location P, have finished writing. Information from different trace calls can thus be written to the buffer in parallel. More than one buffer can be used.

Title: Testing the correctness of image data transferred between memories
Inventor: CHANG VAM
IPC: G06F11/16
Filed: 1999-01-25
Abstract: The invention provides a method which enables the transfer of image data by a bit-block-transfer (Bitblt) hardware engine in a display chip of a computer system to be tested directly in a DOS environment without having to install a windowed operating system. The method comprises storing, 100, image data A in a first location B in system memory; using the Bitblt engine to copy, 120, the data from B to a first location C in display memory, copy it, 140, from C to a second location D in display memory, and copy it, 160, from D to a second location E in system memory; then comparing, 170, the data at B with the data at E. Any discrepancy indicates an error, which can be localised by comparing (Fig 2) the data at B, C and D. For colour image data, the test method may be extended (Fig 3).
