Abstract: The invention concerns a probabilistic method and automatic control (3) for preventing and regulating an interruption of a multistage and multilink industrial production glow, to optimise said production flow while controlling industrial impact resulting from random chained stress, and applications to factory noise and value at risk of a clearing house. The invention consists in regulating production by means of a probabilistic automatic control (3) with action loop (5) and feedback loop (6). Industrially speaking, said regulating automatic control (3) can be electronically produced by means of a programmed and cabled computer. The action loop (5) of the automatism (3) consists of an inductive probabilistic simulator (11) evaluating the chaining of random stresses in the production chain leading to a probabilistic measurement of the industrial impact I(r) resulting, on the basis of the adjustable level of an industrial stock parameter (r).

Abstract: A method of simulating a local system which is in interaction with other local systems within a global environment. The method includes generating, at a central location, a collection of global sets of values, each representing a possible future global state of the global environment at a future time, and the collection representing a variety of possible future global states. The method also includes transmitting the collection of global sets of values to the local systems. The local systems receive some of the collection, select a local set of parameters, and perform calculations on that data. The collection of values is used as a predictive simulation of the local system.

Abstract: A device (101) for airborne decontamination of a room (3) by mixing using a blown jet (19) and a suction flow (21) that are attached by the Coanda effect (C). Vertical trunk means (103) have a bottom suction end (104) and a top blow end (105). Drive means (106) set the air (A) into motion inside and outside the trunk means. An intake nozzle (118) provides a vertical suction surface (Sa) serving to suck in the air (A) as a suction stream (55) parallel to the floor (6) and attached thereto by the Coanda effect (C). A blow nozzle (129) using the surface effect at the ceiling (20) presents a frontal porous blow surface (Ss). It produces a primary jet (19) of air that is attached to the ceiling (20) by the Coanda effect (C). Decontamination means (127) decontaminate the air (A). The effective area (Sae) of the suction surface (Sa) is less than the effective area (Sse) of the blow surface (Ss).

Abstract: Mobile aeraulic isolation device (1a) with variable geometry multi-block air diffusion chamber (4), comprising at least two mobile plenums (5,6) to protect a sensitive area such as a bed (2) against contaminating airborne aerosols. It comprises an air diffusion chamber (4) formed of at least two rigid plenums (5,6) mechanically connected together so as to be mobile relative to one another, and having a lower air diffusing surface (7,8) substantially planar and porous to air.

The device 1a) is characteristic in that it comprises complementary means for absolute movement (13) of the group of two rigid plenums (5,6) relative to chassis (12).

Abstract: Ionic emission electrostatic device (1) for depositing on the surface (sp) of a multitude of aerosol particles (p1, p2, . . . , pn) within a fluid (F), a quasi-homogeneous quantity of ions (iq). This electrostatic device (1) is constituted by a conductive discharge corona electrode (EC) and a noncorona conductive receptor electrode (ER). The pseudo-planar active face (SA) of its receptor electrode (ER) is covered by a plurality of craters with sharp edges, in a closed pseudo circle, exhibiting on their end edges (Ai) a section of minimum bend radius, and enclosing the orifices (O1, O2, . . . , On) and terminating towards the outside of the active face (SA). The craters are distributed quasi-uniformly on the active face (SA), in its two geometric directions. The surface flow of ions (iq) originating from the corona electrode (EC) and in the direction of the active face of the receptor electrode (ER) has an increased homogeneity.

Abstract: A method and device for chemical or biological analysis by a sensor provided with a monolithic chamber in the form of a multi-microtubular sheaf and a lateral integration measuring transducer. The method improves the usual method for a sensor evaluation of an analyte concentration in a fluid sample by multi-canalising in parallel the fluid sample fraction through channels of a monolithic reaction chamber, positioning a transducer system fully outside the surface of the shell of the reaction chamber and strictly in front of the lateral face thereof, carrying out an integral measurement of signals generated by the analyte combination and a receiver, which is also arranged in the reaction chamber, by a lateral transducer system coevally in all channels of the reaction chamber such that the presence of the analyte in all channels of the reaction chamber is simultaneously and globally quantified.

Abstract: The invention concerns an electrostatic ionic emission device (1) for depositing on the surface (sp) of a plurality of particles (p1, p2, pn) aerosols within a fluid (F), a quasi-homogeneous amount of ions (Iq). The device (1) comprises a discharge corona conductive electrode (EC), and a non-corona conductive receptor electrode (ER). The pseudo-planar active surface (SA) of its receptor electrode (ER) is covered with a quasi-uniformly distributed plurality of sharp-edged craters, enclosed by a pseudo-circle, having on their end edges (Ai) a section with minimum bend radius, and enclosing orifices (O1, O2, On), emerging outwards of the active surface (SA). Said sharp-edged craters are quasi-uniformly distributed on the active surface (SA), in both its geometrical directions. The surface flow of ions (Iq) derived from the corona electrode (EC) towards the active surface of the receptor electrode (ER) has increased homogeneity.

Abstract: The invention concerns a volume generator (1) of chaotic electrostatic field (E), locally amplified, to subject a fluid (U) loaded with aerosol parties (P, p) to the action of an electrostatic field (E) highly variable in amplitude and orientation locally. This generator (1) includes: an induced electrostatic module (2), consisting of a porous dielectric material (md), two porous electrodes with electrostatic induction (4, 5), an electrical current source (6), and a device for boosting the fluid. The electrostatic module (2) consists of a three-dimensional grid system (Rxyz) having at least locally three-dimensional periodicity (or pseudo-periodicity) in at least three directions. Each grid of the system consists of an externally convex and internally concave elementary cell recessed in its center for including a compact elementary empty cellular volume (V1), that is with transverse dimensions (dx1, dy1, dz1) of the same order of magnitude in the three directions.

Abstract: Apparatus for reading optically a scene made up of symbols on a transparent medium comprises a transparent flat plate on which the scene is supported. An illumination system on one side of this plate illuminates at least part of the scene. An optical reader device on the opposite side of the plate incorporates an optical sensor. A pneumatic skid is moved over the opposite side of the plate and has a recess in its surface facing the plate in which the sensor is accommodated. Thus the scene is scanned by the sensor as the skid is moved over the plate.

Abstract: A two-dimensional pattern made up of primary and secondary shapes having different levels of contrast, e.g. a printed circuit card, is visually inspected by means of a line-by-line scan, e.g. using a beam of light. A data structure or "file" is built up representative of the current scan line and is compared with a similar file representative of the accumulated scan history so far. The accumulated history file is then updated, the next line is scanned, and the sequence repeats. Allowable changes in shape between scan lines can be coded in the form of multiple-entry digital tables. Non-allowable changes cause alarms to be generated. Allowable changes can easily be altered by downloading a new set of tables, thereby enabling the method to be readily adapted to inspecting different types of object. The method is suitable for implementation by hard-wired logic for high-speed real-time operation.

Abstract: Patterns (f) in a scene (S) are analyzed in order to automatically distinguish symmetrical perceptible areas (P) in the pattern (f), even if said symmetrical perceptible areas (P) are intersected by auxiliary patterns (F). A digitized image (Id) is used, and a test point (cO) located inside the digitized pattern (fd) is used as a starting point. A sequence of circles of increasing diameter is drawn around the test point. Whenever one such circle (CO.sup.i) intersects the digitized pattern (fd) a new center (c1) is chosen, offset from the preceding center (c0) in a direction going away from the point of intersection. By iteration, a sequence of test points (cn) is thus constructed which, for a symmetrical pattern, converges on its center of symmetry (c).
