Title: Vehicle air bag venting arrangement
Inventor: GERMAIN FREDERIC
IPC: B60R21/233
Filed: 1995-07-04
Abstract: An air-bag has a venting opening initially sealed by a removable cover 10. The cover is associated with an elongate flexible element, such as a wire or cord 8, having one end secured to the cover and the other end secured to part of the bag 9.

Title: A method of forming indicators and push-button members by locating an element thereof inside a mould
Inventor: YOUNG ARTHUR DAVID
IPC: H01H9/18
Filed: 1996-10-02
Abstract: During the formation of an indicator or push-button assembly, a locating body (30) is engaged on the rear surface of a front plate (16), for example, by engaging on weldstuds (26, 28). This locating body (30) carries an outwardly extending tab (38). The front plate (16) is then located in a mould by engaging the tab (38) in a recess therefor and a body member (40) is moulded thereon. Because the front plate is accurately located in the mould, the relative orientation between the front plate and the mould body is similarly accurate. This means, for example, that when the resultant push-button member is engaged in a housing, it is ensured that any indicia (18, 20) carried thereon are upright.

Title: A server selection method in an asynchronous client-server computer system
Inventor: BANKS ANDREW DAVID JAMES
IPC: G06F9/46
Filed: 1998-04-14
Abstract: Messages from a client application 111 are placed in a queue 112b for subsequent transmission to a selected one of a number of servers 121-123. The server to which each message is to be sent is determined when the message is placed into the queue, based on the server availability data known at that time and without waiting for availability data for each and every server. This eliminates an unnecessary source of delay. If the server availability data is updated before the message is transmitted, the server selection may be altered.

Title: Post-processing removal of blocking artefacts from a block-based image by filtering
Inventor: PAIK JOON KI
IPC: H04N19/60
Filed: 1998-04-09
Abstract: A block-based image processing method and an apparatus therefor, in which blocking artifacts caused by a block-based image processing can be removed by using spatial adaptive filtering based on image restoration theory. The block-based image processing method, for removing blocking artifacts induced in processing an image in blocks of a predetermined unit size, includes the steps of: (a) dividing the processed image signal into blocks of the predetermined unit size; (b) detecting an edge direction of the image for each block divided; (c) band-pass filtering the processed image signal to obtain plurality of filtered image signals equal in number to the possible types of edge direction; (d) selecting one of the band-pass filtered image signals for each block, according to the detected edge direction; and (e) synthesizing the selected image signals for all the blocks to obtain an original signal from which the blocking artifact is removed. Each of the filtered images (110-114, fig. 8) of step (c) has removed therefrom a unique one of the plurality of possible directions of edge that the artefact of the unfiltered image (IN2) may actually correspond to. Edge direction is determined (106) using discrete cosine transforms (104) and this information is used to select (116) the correct filter output from the plurality of filter outputs (110-114).

Patent GB-2328298-A (GB)
Title: Cache performance improvement through the use of early select techniques and pipelining
Inventor: MATICK RICHARD EDWARD
IPC: G06F12/08
Filed: 1998-07-06
Abstract: A computer memory hierarchy comprises a level one (L1) cache with access/cycle time equal to or faster than a processor cycle time which can deliver at least a logical word or words needed by the processor on each cycle for an L1 HIT and an L2 cache including a directory and data array in which the L2 directory is accessed upon a MISS to the L1 cache. The L2 data array has a mapping from the L2 directory to the data array such that one block needs to be accessed from the data array, the L2 directory performing required address translation and, upon a HIT, starting access to the L2 array for a specific block required for reloading into the L1 cache, and upon a MISS, the L2 cache requesting a block reload from a next level of the hierarchy. The invention allows a DRAM L2 cache to be used in a computer memory hierarchy without compromising overall system performance. To achieve this, the total DRAM access is minimised as much as possible by use of early select techniques and pipelining. The larger DRAM capacity compared to a SRAM gives a substantially better HIT ratio which compensates for any small degradation due to access time.
