Title: Rendering 3-D images without clearing Z buffer for each new frame
Inventor: MARTIN KEVIN
IPC: G06T15/40
Filed: 1993-12-06
Abstract: A method for rendering of three dimensional images on a video subsystem which does not include clearing of the Z buffer at each frame includes establishment of a Z buffer and a sequence number in memory, where the sequence number is incremented with each successive frame rendered and the Z buffer is cleared when the sequence number reaches a predetermined value; the Z buffer is thus recycled a number of times between clears. In a more elaborate implementation, the precision of the Z buffer is adjusted to permit clearing of the Z buffer to occur either as the result of the sequence number reaching a predetermined value or as the result of the accrual of a predetermined amount of time allocated for clearing, referred to as scheduling. The scheduling method can be applied to a wide range of accounting tasks within a system. In addition, a related method for recycling the image buffer is also disclosed in which multiple colormap ID's are used to distinguish data included in a current frame from data in a prior frame, where the colormap ID's associated with the prior frames all map to the background color, leaving to be displayed only the data of the current frame. <IMAGE>

Title: Dispensing heated food products
Inventor: HAMILTON LESLIE GEORGE
IPC: H05B6/80
Filed: 1993-12-15
Abstract: An apparatus for dispensing heated food products comprises a housing 11, in the upper part of which is a freezer compartment 27 having a trap door 69 and at least one magazine in the form of an wire helix 31 adapted to carry food packages P. Beneath the freezer compartment there is a cylindrical r.f. microwave oven 15 supported for rotation about its longitudinal axis. The wall of the oven has an aperture 49. Control means is operative to control the angular displacement of the oven 15 such that, during a cycle, a package P, released from the helix 31, passes through the aperture 49 into the oven 15. Further rotation of the oven 15 brings the aperture 49 to a position at which it is closed by a radiation opaque plate supported by the housing 11, magnetrons of the oven 15 being then activated to heat-treat the package. Further rotation of the oven brings the aperture 49 to a position whereat the heat-treated package P is discharged to a retrieval chute 17. <IMAGE>

Title: Multichannel Video Data Storage
Inventor: HARRADINE VINCENT CARL
IPC: H04N5/926
Filed: 1994-03-18
Abstract: A storage mechanism is shown utilising a single data recorder 2 from which multiple channels of compressed video data may be simultaneously accessed. The data access to and from the data recorder 2 via a single data access path takes place at a higher data rate (f1, f2) than the data rate (f3, f4) at which that compressed data needs to be decoded to support a video signal. A video router 14 is used to direct the reproduced data stored within two data channel buffers 6, 8 to respective JPEG decoders 24, 26 where they are decompressed into a signal suitable for driving two digital monitors 16, 18. In operation, a segment of compressed video data for one channel is recovered from the data recorder 2 and stored within one of the buffers 6, 8 from which it is continuously read at a lower data rate (f3, f4). The data recorder 2 then cues to another part of the medium from which data for the second channel is reproduced and stored within the other of the buffers 6, 8. The process is then repeated. <IMAGE>

Title: Noise prevention in D/A or A/D conversion with two stage stepped gain control by using zero crossing detector to time gain changes
Inventor: HIMENO TAKUJI
IPC: G10L25/09

Filed: 1997-05-22
Abstract: A radio selective paging receiver includes a reception unit 1, a control unit 2, and a timepiece unit 3. The reception unit 1 is controlled to start reception in synchronism with at least a standard time, and receives a radio signal modulated by a selective paging signal containing time information in transmission information, and demodulates the radio signal. The control unit 2 controls operation of the reception unit 1, and determines call reception and time information in accordance with the demodulated signal, and processes the call reception and the time information. The timepiece unit 3 at least temporarily holds the obtained time. In setting the time information obtained by operating the reception unit to the timepiece unit, the control unit adjusts the time with a predetermined time lag, such that a carry to the minute or hour unit is not generated at the same time as data for that receiver is received.

Abstract: First spring means 14 act on the lift valve 1 in the valve-closing direction, and second spring means 16 act, at least intermittently, in the valve-opening direction. The lift valve 1, or a valve tappet 4 which actuates the valve, is connected to a control piston 8 which is arranged in a working space 11 and is capable of being loaded with a working fluid on both sides. In the region of its end positions, the piston 8 delimits a pressure space 28, 29 belonging to the working space but capable of being separated hydraulically from it. The pressure of the working fluid is capable of being regulated via a pressure source together with a switching valve 27 and a supply line 45, and the prestressing force of the second spring means 16 is capable of being regulated during the operation of the valve control device. The pressure of the working fluid in the pressure space 28 can be regulated even when the pressure space is separated hydraulically from the working space 11 and the pressure space 28 can be loaded with pressure in order to trigger the valve movement.

IPC: F16J15/12
Abstract: 971,144. Gaskets. W. R. GRACE & CO. March 19, 1963 [March 19, 1962], No. 10897/63. Heading F2B. [Also in Division B5] A cylinder-head gasket for an I.C. engine, comprises a layer 11 of resilient material, Fig. 2, bonded to a thin metal sheet 5 by means of an adhesive 10. A metal sheet may be bonded to both sides of the resilient layer. In a method of making the gasket a composite sheet composed of resilient material and metal sheet adhesively bonded together it cured wholly or partially by heating under pressure in a platen press. The laminated sheet is then cut to size and perforated to provide combustion chamber and water circulation openings by means of a die. The die may be first pressed through the metal sheet so that the metal extends downwardly over the edges of the openings cut in the gasket. Alternatively, the openings are protected by separately formed metal grommets adhesively secured in and around the gasket openings. In Fig. 2A, integral grommets may be formed from the metal sheet 5A by extending it over the periphery of pre-cut gasket holes 6 and return folding the edge of the extended sheet and adhesively securing it to the resilient layer 11. The resilient layer may be formed from a cured rubberized mineral fibre sheet prepared by rolling a mixture of mineral fibres, rubber, fillers and a solvent. The mineral fibre may be asbestos, glass fibre or rock wool and the rubber may be natural or synthetic such as neoprene, acrylonitrile-butadiene or butadienestyrene. A typical composition of a fibre sheet comprises 62 parts asbestos, 11 parts cellulose, 8 parts phenolic resin, 14 parts acrylonitrilebutadiene and 3 parts carbon black. The metal sheet may be of copper, aluminium, steel, tinplated steel or aluminium alloy. The adhesive may be prepared from elastomeric materials such as natural or synthetic rubber, thermosetting or thermoplastic resins or a cured mixture of these resins and may be applied by brushing, rolling or spraying. Selected resins and resin mixtures are phenolaldehyde resins, epoxy resins, polyvinyl acetate, phenolformaldehyde resin plasticized with polyvinyl butyral, butadieneacrylonitrile mixed with phenolic resin and nylon mixed with phenolic resins. Methods of making gaskets and comparative test results are given.
