Filed: 1994-11-04
Abstract: A turbocharger module (100) for a turbocharged internal combustion engine comprises turbocharger cartridges (850), each having a turbine rotor (814) and a compressor impeller (812) mounted on a common shaft (816) running in bearings (809). Each cartridge is held in a bore (851) in a wall (90) of a supporting enclosure (9), with its turbine rotor projecting into the enclosure and its compressor impeller outside the enclosure. A turbine housing (800) is fitted tightly to an internal wall surface region (807) surrounding each bore to provide a low thermal resistance path to heat flow by conduction from the turbine housing (800) into the wall (90). When installed in the bores, the turbine rotors of the cartridges fit into the turbine housings, the cartridges being held concentric with the turbine housing by a spigot (870) having a close fit in a circular register (871) in the turbine housing. The spigot and the register contact each other over an annular region which is substantially smaller in area than the area of contact between the turbine housing (800) and the internal wall surface region (807), the spigot and the register providing the only significant region of direct mechanical contact between the turbine casing (800) and the cartridge (850). Hence, during operation of the cartridges, heat from the turbine casing is shunted away from the cartridges into the wall (90) of the enclosure (9). Preferably, the wall is actively cooled. <IMAGE>

Title: Processing image signals at an object boundary
Inventor: ARBEZ PATRICK
IPC: G06V10/28
Filed: 1999-04-06
Abstract: An image frame is replayed from a store and an operator manually identifies control positions on or near the boundary of an object 301. Pixel values are compared around the control positions to define local colour transitions and the boundary is completed by interpolation. Pairs of image areas near respective control positions are processed to determine colour values, specifically regions in colour space which include the colours within the areas. The region of colour space lying between the identified regions is used to generate a matrix transformation which is operable within RGB colour-space to generate mask blending values between full on and full off. Thus a soft bounded region may be combined with a fill to produce a multi-bit key, matte, alpha or mask layer for selectively removing the foreground or background to allow compositing with images obtained from elsewhere, without the need for recording the foreground against a specific type of background.
