A data buffer (23) is positionable between processing devices, such as microcontroller (21) and a digital signal processor (22). Messages are transmitted between the devices via a dual port RAM buffer (31). The amount of storage allocated for transfers in each direction is adjustable via a size register (42) so that, at any particular time, the optimum amount of storage is provided for a transfer ...

A hollow fiber separatory module (10) includes an annular hollow fiber bundle (12) housed within a pressure resistant shell (22). The fiber bundle (12) is encased within an impervious barrier (18). Pressurized fluid is fed into the channel (34) formed between the impervious barrier (18) and the shell (22) and passes into the fiber bundle through an opening (19) in the impervious barrier. The fluid...

A compact, high resolution, full color three-dimensional projection system (50) has a single display system and utilizes image polarization for color multiplexing (Fig.2).

Method making it possible to discharge at a reduced rate, in the form of drops, a gel, in particular a hair styling gel, having a viscosity of between 2 and 8 pascals.seconds. According to this method, the gel (G) is projected under pressure into a channel ending in a restricted opening (44) and a gas (P) under pressure is introduced into the said channel in order to form drops of gel separated by...

A method and arrangement for recording imagery for subsequent or substantially simultaneous viewing, including recording partial and adjacent angles of view of imagery, from at least two spaced apart angles of view, and segmenting and separating said partial and adjacent angles of view, such that imagery so recorded, when viewed on a screen surface, has depth of imagery and appears substantially i...

In a system for compressing stereoscopic video signals, left and right stereoscopic video image signals are provided by a pair of, for example, synchronized cameras (10,11). The left video image signal is applied to compression apparatus (12-19) which compresses the left video signal according to a flatfield signal compression protocol such as the MPEG (Moving Pictures Experts Group of the Interna...

A glass mat reinforced thermoplastic semi-finished sheet material comprising thermoplastic resin and at least two needled continuous and/or chopped glass fibre strand mats is disclosed as well as a method for its manufacturing and its use. Each of said glass mats is needled from the two sides in an asymmetrical way, so that the number of fibre ends protruding from the two major mat surfaces are pr...

MODULAR PNEUMATIC ACCUMULATION CONVEYOR An accumulation conveyor includes a product sensor that is positioned along the conveyor at a particular zone for sensing the presence of product at that zone and for causing actuation of the zone upstream of that product sensor with respect to product movement along the accumulation conveyor.
