Abstract: The invention relates to a multitask processing system including a data bus and a command bus. Each one of a plurality of operators is provided to perform a processing determined by an instruction and is likely to issue a command request in order to receive an instruction from the command bus and to issue a transfer request on response to an acknowledgment of the command request, in order to receive or provide data being processed, through the data bus. A memory controller arbitrates the transfer requests and manages the data transfers on the data bus between the operators and a memory. A sequencer arbitrates the command requests, determines instructions to provide the operators with, and manages the instruction transfer through the command bus.

Abstract: The invention provides a method of positioning an electrical control signal (S1, S1bis) for an electro-optical modulator (5) relative to the characteristic (VA, VB) of the modulator (5), in which method a disturbing signal (S2, S2bis) is superposed on the control signal (S1, S1bis) and the position of the control signal (S1, S1bis) is adjusted as a function of the value of a component in the output signal of the modulator (5) corresponding to the applied disturbance (S2, S2bis), in which method the disturbance (S2, S2bis) is superposed on the control signal (S1, S1bis) when the control signal takes a value (VA) that ought to correspond to a minimum slope point (A) of the characteristic, and the positioning of the control signal (S1, S1bis) is adjusted in such a manner as to minimize the amplitude of the disturbance as output due to said disturbance of the control signal (S1, S1bis), the method being characterized in that the characteristic of the modulator (5) includes a second minimum slope point (B) corresp

Abstract: Device for treating lesions of the wall of blood vessels, in particular false aneurysms, by coagulation, which device comprises an introducer with value and with removable needle, a filament which is able to be introduced into the pocket of this aneurysm and to roll up on itself therein, and a introducing the said filament into the pocket through the introducer.

Abstract: The present invention relates to a device for protected angioplasty, intended for the implantation of luminal endoprosthesis (or stent) in critical areas such as carotid or vertebral arteries, where protection of downstream-situated organs is highly desirable. The device comprises a central stent pusher part comprising a microcatheter bearing at its distal end an atraumatic tip, the atraumatic tip being prolonged by a tip balloon part comprising an inflatable occlusive balloon which may be inflated with a physiologically acceptable fluid at predetermined rates, a fluid-releasing section extending at the proximal the of the occlusive balloon, said releasing section being able to release the fluid from the balloon into an upstream section of the vessel when the pressure of the fluid reaches a predetermined level.

Abstract: An integrated circuit data processing structure and method for performing a discrete cosine transform (DCT) makes the correspondence between a table f(x,y) of N.times.N data and a table F(u,v) of N.times.N coefficients according to the following relation: ##EQU1## The innovative structure uses: a memory containing a data table;a memory of the productsP=.vertline.cos[n(x,u).pi./2N].multidot.cos[n(y,v).pi./2N].vertline., with:p(x,u)=Sgn[p(x,u)].multidot..vertline.cos[n(x,u).pi./2N].vertline.p(y,v)=Sgn[p(y,v)].multidot..vertline.cos[n(y,v).pi./2N].vertline.where n(x,u) and n(y,v) are integers ranging from 1 to N-1;a table of the signs of p(x,u) and p(y,v) and values of n(x,u) and n(y,v) addressing the product memory (3);a coordinate generator sequentially providing value pair (u,v) and, for each pair (u,v), all the values of pair (x,y);a multiplier calculating the product of P by a data combination of the data memory; andan accumulator of the results of the multiplication.

Abstract: A method masks errors in a transmission system of a picture sequence including a first series of pictures that are autonomously coded by pixel blocks (intra coding). Each picture of the first series is followed by several pictures of a second series of pictures that are differentially coded by blocks with respect to at least one reference picture of the first series of pictures (inter coding). The codes of each block of the second picture series comprise at least a motion vector between the pixels of the block and the pixels of the elements of the reference picture. The method provides for adding, to the data corresponding to each block of an intrapicture, data indicating the motion vector of this block with respect to at least one additional picture, and, if a transmission error is detected, the error blocks of the intrapicture are processed like error blocks of an interpicture.

Abstract: According to the disclosed method for the soldering of wires of components, at least one wire is stamped to make it lose its symmetry of revolution. The result thereof is one or more impressions. A solder strip is crimped by deformation around the wire to form a solder preform held still by the impressions, which leaves free a surface of the wire. The component to be soldered, held against said surface of the wire, is soldered by reflow process. Application: the soldering of components such as disk ceramic capacitors.

Abstract: Apparatus is disclosed for cumulative summing and compressing data items each of which is comprised of b binary elements.

Abstract: The disclosure describes a device for locating faults in a working storage arranged in rows and columns.The device includes an auxiliary storage which holds a sequence of test words and means for cyclically writing the test words into the working storage and reading the test words out of the working storage. A bit for bit word comparator compares the words read out of the working storage with the words read into the working storage and detects bits of the words which do not match in order to identify defective components. First and second registers record the row and the column to which the defective component belongs.
