Title: Interactive source-code software production method modeling a complex set of functional modules
Inventor: GALY PAUL
IPC: G06F17/50
Filed: 1991-04-17
Abstract: ABSTRACT OF THE DISCLOSURE The  invention concerns  an interactive  source-code software  production  method  modeling complex  sets  of functional modules.    This   method  consists  of  using   in  a  computer connected   to   display   means   a   graphic   editing software(6)  stored  in  a memory  of  the computer  and drawing  up  graphic  plates  describing  complex  logic circuits  of the module  from a library (10)  of graphic symbols,  a  software (9)  to produce  a  file (11)  for precoding   symbols,  a   software  (12)   allowing  for coherent control  between the symbols of each plate, and a  software (15) for  coherent controlling  the temporal chaining  of the order  and execution conditions  of the plates.  The  method  also consists  of  storing in  the memory  a  control  dictionary  (17)  for  updating  the plates.  Finally, the  source-code software  is produced from  a  software (18)  processing the contents of  the precoding file and that of the dictionary.            Figure 2.     SP 6143.69 DC

Title: Fusible link
Inventor: GUELI CARMEN
IPC: A62C37/12
Filed: 1991-05-08
Abstract: A fusible link has two generally oval members in overlying relationship, the two members having relatively flat surfaces confronting one another. One member has a rectangular slot therein having tapered surfaces and the second member has a projection having beveled sides complementing the tapered surfaces. The projection is accommodated in the slot and seats on the tapered surfaces of the latter to provide a space between the confronting surfaces. The space is filled with a eutectic alloy which secures the members together. Pins on the members maintain the thickness of the space uniform. When the alloy is heated to a predetermined temperature it melts, thereby enabling the members to separate.

Title: Vlsi architecture for the implementation of real-time order statistic filters
Inventor: MURTHY N RAMA
IPC: H03H17/02
Filed: 1991-10-17
Abstract: A VLSI ARCHITECTURE FOR THE IMPLEMENTATION OF REAL-TIME ORDER STATISTIC FILTERS                 N. Rama Murthy and M.N.S Swamy Centre for Signal Processing and Communications Department of Electrical and Computer Engineering Concordia University 1455 de Masionneuve Blvd. W.  Montreal, Quebec H3G 1M8 ABSTRACT This invention relates to the real-time implementation of a class of nonlinear digital filters known as Order Statistic Filters.  These type of filters have found application in several areas of signal and digital image processing such as the processing of pictures obtained from satellites, x-ray and other sources. Real-Time implementation of order statistic filtering as used in signal and image processing involves computing, at every sample output instant, the ranked order of N input signal samples in a window which gets periodically updated with the arrival of a new input sample, where N is usually odd and is assumed to be so from now on.  Let xp(n),p=1,2,...,N be the samples inside the window wN(n) at the n th time instant, i.e., wN(n)={x1(n),x2(n),...,xN(n)} Define a new window wN as the one obtained from wN(n) by sorting the samples xp(n), p = 1,2,..., N inside wN(n) in the increasing order of algebraic value, i.e., wN(n) = {x(1)(n),x(2)(n),...,x(N)(n) } where x(1)(n) ? x(2)(n)?...? x(N)(n). The output Y(n) of an i th Order Statistic Filter (OSF) with input wN(n)is x(1)(n). In the case of one dimensional order statistic filtering, wN(n) gets continuously updated at every sampling instant n with the deletion of the oldest sample (in time) and the inclusion of the latest sample (current or new sample).  In the case of 2-D median filtering of digital images, a two dimensional mask of size N1 x N2(where usually both N1 & N2 are odd) centered on a pixel x(u,v) being processed at instant n, is used to select N = N1 ?N2 samples of wN(n).  In this case, as the mask is moved along the digital image for processing of all the pixels in the image, more than one old sample gets deleted from wN(n) and an equal number of new samples get included in wn(n). In practice, the signal samples that constitute wN(n) are obtained from the output of an A/D converter used for quantization and coding. If the largest possible sample inside wN(n) at any instant has r-bit binary representation, then real-time order statistic filtering involves computation of the r-bit orderstatistic at every sampling instant (running order statistic) which is a computationally challenging task to implement in real-time for the processing of video signals.

IPC: H01L39/14
Filed: 1991-11-01
Abstract: A superconducting device comprises a substrate, an extremely thin superconducting channel formed of an oxide superconductor on the principal surface of said substrate. A superconducting source electrode and a superconducting drain electrode of a relatively thick thickness is formed of the oxide superconductor on said superconducting channel separated  from each other but  electrically connected by said superconducting channel, so that a superconducting current can flow through said superconducting channel between the superconducting source electrode and the superconducting drain electrode.  A superconducting gate electrode is formed of the oxide superconductor through a gate insulator on said superconducting channel for controlling the superconducting current flowing through said superconducting channel. And a side insulating region is formed to completely cover each of opposite side surfaces of the superconducting gate electrode. The superconducting channel and the gate insulator are formed of the same oxide thin film of which oxygen amount is locally decreased and said gate insulator being formed of a compound oxide which is composed of the same constituent elements as those of the oxide superconductor of which the superconducting channel is formed but includes the oxygen amount less than that of said oxide superconductor. And the superconducting gate electrode is surrounded by the superconducting channel, the superconducting source electrode and the superconducting drain electrode but electrically isolated from the superconducting channel, the superconducting source electrode and the superconducting drain electrode by the gate insulator and the side insulating region.
