Patent EP-0505782-A3 (EP)
Title: Multi-function network
IPC: H04L7/033
Filed: 1992-03-05
Abstract: A multi-stage switch architecture for providing for using a single switching component in multiplicity to create a single network capable of performing a multiplicity of functions. One function of the disclosed network is to circumvent the traditional blocking problems in multi-stage networks by implementing ALTERNATE PATHS between all N and M devices within the same network. This permits a non-blocked path between 2 devices to be found by "rearrangeability" - the act of trying or searching different alternate paths until a non-blocked connection is established. The rearrangeability architecture disclosed is implemented completely in hardware, and is performed automatically and transparently in relation to the software. A second network function permits the ALTERNATE PATHS to be used selectively for GUARANTEED DELIVERY - a special high priority mode of transfer which will guarantee that the connection will be made to an IDLE device as rapidly as possible, even when "Hot" spots in the network traffic patterns are encountered. In addition, the ALTERNATE PATHS provide another function of providing a more fault tolerant network than provided by state-of-the-art solutions. As a result of our inventions we provide a single, unidirectional, unbuffered, multi-stage network capable of doing the total network job consisting of multiple functions. The functional complexity provided usually requires several state-of -the-art multi-stage networks to perform the equivalent job. The single network disclosed here allows traffic in both directions, provides for non-blocking via ALTERNATE PATHS and REARRANGEABILITY, incorporates GUARANTEED DELIVERY and FAULT TOLERANCE, and yet is very compact and inexpensive to implement. In addition, the network is modular in nature and permits easy adaptation to any sized system. <IMAGE>

Title: Real-time mr imaging inside gantry room
IPC: G01R33/28
Filed: 1992-01-07
Abstract: Continuously updated real-time magnetic resonance imaging processes are used to display an MR image volume to an operator and/or patient co-located with the MRI magnet, viewing console (30) and other elements of an MRI system within the same shielded gantry room (10). A CRT display may be used for lower field MRI systems while liquid crystal displays may be necessary for higher field MRI systems since the viewing console is to be co-located within the shielded gantry room near the MRI magnet assembly. Suitable RF shielding (38) is provided to RF-isolate the viewing console and its related power and video signal cables from the MRI RF coils being used to monitor selectively weak NMR signals emanating from the image volume within the magnet assembly. When used with the open access MRI magnet assemblies, such real-time viewing ot eh image volume within the gantry room permits performance of simultaneous patient procedures guided by real-time visual feedback to the patient and/or doctor, nurse, patient attendant and the like while located within the gantry and room and having direct access to the patient anatomy within the image volume. <IMAGE>
Patent EP-0592765-A3 (EP)
Inventor: KURAGAKI TAKESHI
IPC: H01L29/73
Filed: 1993-05-07
Abstract: A method for producing a semiconductor device includes
growing a collector layer (2), a base layer (3), and an
emitter layer (4) on a substrate (1); forming an emitter
electrode (5), a tungsten film (13), and a silicon film (14)
serving as an etching stopper on a prescribed region of the
emitter layer (4); etching the emitter layer (4) using
above-described films (14,13) and electrode (5) as a mask to
expose the base layer (3); forming side walls (7) on
opposite side surfaces of the films (14,13), electrode (5),
and layer (4); forming a zinc oxide layer (8) as an impurity
diffusion source on the whole surface of the substrate and
performing a diffusion to produce high impurity regions (9)
in the base layer (3); removing the zinc oxide layer (8) by
a wet etching using hydrofluoric acid as an etchant;
depositing a base metal (11) on the whole surface of the
substrate and removing an unnecessary portion of the base
metal by ion milling to form base electrodes (111);
selectively removing the silicon film (14); and forming a
leading electrode (16) in contact with the tungsten film
(13). Since the silicon film (14) is not etched by
hydrofluoric acid when the zinc oxide layer (8) is removed,
the emitter electrode (5) is not adversely affected by the
ion milling for removing the base metal (11), resulting in
an HBT with a reliable emitter electrode.
Patent EP-0565223-A3 (EP)
Title: Method for compressing a digital image signal with ordering and formatting coded data and reconstructing partial images from the data
IPC: H04N7/30
Filed: 1993-02-05
Abstract: Editing of information stored on magnetic tape involves relatively 
high picture-in-shuttle transport speeds. A consequence of the high speeds is 
that only a fraction, or a portion, of the data on a track of the tape is usually 
recovered. Hence, data is stored in small, yet complete, segments from which 
portions of the picture, called "snatches," may be recovered.  
     An image signal representing a video picture is compressed using a 
data compression technique that orders and formats image data so that the 
information represented by a snatch can be used by a data decompression 
technique to reconstruct a recognizable image from less than all the digital 
information that defines the image to be displayed. That is why the 
reconstructed image is also called a partial reconstructed image in the 
disclosure. The image comprises several fixed-size image blocks while each 
image block includes sufficient pixel image data to construct and to 
reconstruct, and accordingly to define, a corresponding portion of the image 
to be recovered and displayed. Video data components of a video image are 
converted on a line-by-line basis to generate a set of image blocks, which are 
discrete cosine transformed ("dct") to generate a corresponding set of dct 
coefficient blocks. The dct coefficients are rank ordered from lowest visibility 
coefficient to highest visibility coefficient. Our example of ordering by 
visibility corresponds to ordering from lowest dct frequency coefficient (the 
lower dct frequency coefficients have the higher visibility measure) to highest 
dct frequency coefficient (the higher dct frequency coefficients have the lower 
visibility measure). A data set of dct coefficients is quantized, entropy 
encoded, formatted, synchronized, and error encoded before being provided 
to a communications channel or before being recorded on magnetic tape.  
     A decompression and reconstruction arrangement performs 
functions which are essentially the inverse of the functions performed by the 
compression arrangement. It is typically during the decompression process, 
that the snatches are retrieved and used to partially reconstruct an image of 
the video picture by using some but not necessarily all the dct coefficients that 
define the respective image blocks.

(38) isolates the second firing head (44) from the source of 
actuating fluid pressure until after the first perforating 
gun (34) has been fired, and then communicates the second 
firing head (44) with the source of actuating fluid pressure 
in response to firing of the first perforating gun (34). 
The first firing head (32) provides a time delay during 
which the actuating fluid pressure may be bled off prior to 
the firing of the first perforating gun (34).
