Title: Dynamically configurable, demand driven data processing pipeline
IPC: G06T9/00
Filed: 1989-09-01
Abstract: A dynamically configurable data processing 
pipeline has been described having a set of stages, 
each carrying out a separate data processing 
operation. The pipeline is demand driven in that 
stages obtain input data by calling preceding 
stages, and when called each stage processes its 
input data to produce output data returned to its 
caller. A stage determines which other stage or 
stages to call by inspecting one or more entries in 
the pipeline description table containing pointers 
to the other stages. The pipeline controller 
responds to input commands requesting various types 
of pipeline data processing operations by adjusting 
the pointers in the pipeline description table so 
that only stages necessary to execute the command 
are called.

Title: Device for braking electric motors
IPC: H02K7/102
Filed: 1989-07-28
Abstract: For the purpose of braking electric motors having cage rotors (2), a braking body (6), which is essentially pot-shaped and produced from sheet metal in a deep drawing process, is proposed which has a projection (15), which cooperates with a projection arranged on the cage ring (13) of the cage rotor (2), in order to press the braking body (6) against a brake lining (12). Welded to the bottom (8) of the braking body (6) is a cylindrical sleeve (17) pointing towards the cage ring (13), which bears on the cage ring (13) when the braking body (6) is raised from the brake lining (12). Since the sleeve (17) defines the position of the braking body (6) in the non-braking position thereof, the braking body (6) need not be otherwise machined. <IMAGE>

Title: Preparation of large beads of a styrene copolymer
IPC: C08F279/02
Filed: 1990-01-30
Abstract: A process for producing large beads of a copolymer comprised 
of from about 60 to 99 weight percent of a mono-vinyl aromatic 
monomer such as styrene and from about 1 to 40 weight percent of 
an acrylic acid monomer such as methacrylic acid is disclosed. 
The copolymer beads obtained in high yield by this process are 
much larger in diameter than those obtained by prior art methods 
and are directly suitable for use in molding applications since 
pelletization is not required. The large beads are produced by 
adding a small amount of a water-soluble polymer such as 
polyvinyl alcohol to an aqueous polymerization mixture after 
about 10 to 75% conversion of the monomers has been achieved.
Patent EP-0384718-A3 (EP)
Title: Method of encoded video decoding
IPC: H04N9/68
Filed: 1990-02-20
Abstract: A digital decoder for an encoded video signal has 
three stages. The first stage applies a 
multi-dimensional digital chrominance bandpass filter 
to the digitized encoded video signal to produce a 
chrominance signal, subtracting the chrominance signal 
from the digitized encoded video signal to produce a 
luminance signal. The second stage detects edges and 
peaks in the chrominance signal, and corrects the 
luminance signal where such edges and peaks are 
detected to produce a chrominance corrected luminance 
signal without dot crawl errors. An intermediate 
corrected chrominance signal may also be derived from 
the second stage. The third stage filters the 
chrominance signal, or intermediate corrected 
chrominance signal, to reduce peaks in the chrominance 
signal as well as to enhance edges to produce a 
corrected chrominance signal with minimized cross 
color errors.

Title: Process for making a multilevel interconnection structure
IPC: H01L21/768
Filed: 1990-03-09
Abstract: A process for forming a connection between two 
layers of a multilayer interconnection in a 
semiconductor device comprises the steps of: forming a 
first conductive layer 3; forming on the first 
conductive layer a layer 4 for preventing stress- 
and/or electro-migration of the conductive layer; 
forming an opening 8 through the entire thickness of 
the migration-preventing layer 4, the opening having a 
diameter less than the width of the conductive layer, 
to expose the surface of the conductive layer; forming 
an interlayer insulating layer 9,11 on the migration-­
preventing layer 4 and the exposed surface of the 
conductive layer 3 to cover the layers and to fill the 
opening 8; forming a through-hole 6 having a diameter 
less than that of the opening in the insulating layer 
9,11 to the surface of the conductive layer, the 
through-hole 6 lying entirely within the region of the 
filled opening so that the surface of the conductive 
layer is exposed but the periphery of the opening 8, 
i.e. the remaining part 41,42 of the migration-­
preventing layer 4, is not exposed; and forming a 
second conductive layer 15 on the interlayer insulating 
layer so that, during the formation of the second 
conductive layer, the through-hole 6 is filled with the 
conductive substance of said conductive layer 15 
thereby electrically to connect the first and the 
second conductive layers.  
     Since the periphery of the opening 8 is not 
exposed, an undercut of the subsequently formed 
through-hole 6 due to faster etching of the layer 4 is 
avoided, reducing the danger of contamination of the 
conductive connection.

Patent EP-0482487-A3 (EP)
Title: Apparatus and method for a temperature compensation of a catheter tip pressure transducer
IPC: G01L9/06
Filed: 1991-10-16
Abstract: A compensation circuit for a resistance bridge corrects errors in the response of signal outputs thereof and has a voltage controlled current source across a power input and a ground reference providing a bridge excitation output current proportional to a fixed circuit reference voltage. A buffer amplifier at the power input generates a buffer output voltage proportional thereto. An instrumentation amplifier at the signal outputs generates an initial output proportional to the response therefrom. A programmable gain amplifier at the initial output provides a compensated output independent of the bridge pressure response. A gain correction part of a compensation network compensates for variations in the bridge response and an offset correction part generates an initial offset current in response to the buffer output voltage. An offset correction amplifier generates a correction signal. The buffer output voltage and the initial offset current vary with temperature providing a temperature dependent part of the correction signal. A reference input of the instrumentation amplifier uses the correction signal and modifies the initial output to counteract fixed and temperature dependent parts of offset errors in the signal outputs response. The offset correction part adjusts the fixed part independently of the temperature dependent part. A single resistor adjusts positive or negative values of the fixed part. Another resistor adjusts positive or negative slope of the temperature dependent part. A method compensates the offset errors with steps of energizing the bridge and measuring the output and resistance at two temperatures and at two pressures. The measurements are used to find correction resistances for variations in bridge offset, temperature and pressure response. <IMAGE>

histogram. A rate of dynamic range compression
corresponding to a region of the image signal, in which the
signal value is comparatively large, a region of the image
signal, in which the signal value is comparatively small,

reference. A dynamic range compressing process is carried
out on the image signal with the rate of dynamic range
compression having thus been set. Gradation processing is
carried out on an image signal, which has been obtained
from the dynamic range compressing process, and a processed
image signal is thereby obtained. A visible image is then
