IPC: G06T15/80
Filed: 1996-06-05
Abstract: Methods and apparatus for per pixel depth cueing in a computer graphics system are disclosed. Per vertex depth cue scale factor values and depth cue rendering parameters are determined 110 for the vertices of a triangle to be displayed. Interpolation circuitry 112 determines a per pixel depth cue scale factor and per pixel color values for each of the pixels in the triangle. When the computer graphics system includes texture mapping hardware, a blending circuit 114 combines the per pixel color values and the texture mapped color values to provide per pixel resulting color values. The per pixel depth cue scale factor value, the per pixel resulting color values and a depth cue color are used to determine 116 per pixel depth cued color values for each of the pixels in the triangle. Accurate depth cueing is achieved with or without texture mapping.

Title: Bandwidth allocation in a broadband telecommunications system
Inventor: HAYTER ANDREW TIMOTHY
IPC: H04L12/54
Filed: 1997-03-17
Abstract: A plurality of delay tolerant sources are multiplexed onto an Available Bit Rate (ABR) data communications bandwidth of a broadband telecommunications system. By allocating bandwidth between the plurality of data sources in a predetermined manner, the data storage requirement may be substantially reduced. The bandwidth allocator first calculates the ABR for delay tolerant data sources by subtracting from the network bandwidth the sum of all cell rates allocated to delay critical sources. It calculates an useable ABR cell rate, which is to be allocated to delay tolerant sources, by subtracting from the ABR a predetermined initial cell rate for each of the delay tolerant data sources which are idle (the initial cell rate being a maximum cell rate at which data may be initially communicated when changing from an idle to an active state). A share of the useable ABR cell rate is then allocated to each of the data sources. The system is suitable for transmitting ATM cells.

Title: Hydraulically actuated i.c. engine fuel injector with solenoid-actuated control valve
Inventor: ANDERSON MICHAEL D
IPC: F02M57/02
Filed: 1998-01-15
Abstract: The injector body has a nozzle chamber 22 containing a needle valve member 46 and opening to an outlet 21. A control valve 31 is attached to a solenoid 38 movable between rest and fully energised positions. The solenoid is biassed to the rest position by a spring 39. A piston/ plunger/ barrel assembly is used to pressurise fuel in the nozzle chamber to a fuel pressure that is proportional to the current in the solenoid. Control valve 31 includes a pilot valve member (60, fig.3) in a pilot balance chamber 70, the pressure in which is regulated by controlling the position of the pilot valve member 60 and hence the flow area through the variable flow area seat 73. Since valve member 60 reaches an equilibrium position by the balance between the solenoid/ hydraulic forces and the spring force, the flow area through variable seat 73 is proportional to the solenoid current.

Title: Connection of scrapers to chains for scraper-chain conveyors
Inventor: MEYA HANS
IPC: B65G19/24
Filed: 1998-02-04
Abstract: A scraper-chain assembly for scraper-chain conveyors, comprises a scraper (4) connectable to the horizontal chain links (9), and vertical chain links (10) hooked into the horizontal chain links (9) are provided with longitudinal limbs (10") whose thickness dimension is smaller than that of nose parts (10'). For the scraper connection, the scrapers (4) have coupling and locking pins (15), which extend through internal openings (11) of the horizontal chain links (9), between the hooked-in vertical chain links (10) and which protrude from the internal openings (11) to form locking pieces (15') which serve to secure the scrapers (4). In this case, the width of the locking pieces (15') is designed to match the configuration of the horizontal and vertical chain links (9,10) in such a way that the coupling and locking pins (15) of the scrapers (4) can be pushed freely into the internal openings (11) of the horizontal chain links (9), when the vertical chain links (10) hooked into these internal openings (11)are pivoted out of the chain axis into a vertical position (Figure 4). By pivoting the vertical chain links (10) back into the normal position, positive locking of the scrapers (4) to the horizontal chain links (9) automatically results (Figure 3). The longitudinal limbs (10") may have a non-round cross-section.

Title: Vehicle closure systems
Inventor: TALBOT KEVIN TREVOR
IPC: G07C9/00
Filed: 1998-06-09
Abstract: A system for effecting closure of one or more vehicle windows 30 comprises a portable transmitter unit 14 and a body control unit 12 which can communicate via an alternating magnetic field produced and detected by a pair of conducting coils 16a, 16b, and via a radio frequency transmitter 24 and receiver 22. On transmission of a R.F. closure request signal from the transmitter unit 14, a confirmation request signal is sent by the body control unit 12 via the magnetic link. The confirmation request signal is repeated during closure of the window. The transmitter unit 14 responds to each confirmation request signal by transmitting a R.F. confirmation signal, receipt of which enables raising of the window to be initiated or continued. Closure of the window is only initiated if the transmitter unit 14 is within the relatively short range of the magnetic link, and only continues while it remains within range. This reduces the danger of a person becoming trapped by the closing window without the operator of the transmitter unit realising.
