Abstract: A system for packaging disposable endoscope sheaths (22) so that they do not become contaminated prior to use during shipment, storage and installation on an endoscope (10). The packaging system also prevents the spread of contamination after use while the sheath is being removed from the endoscope and then discarded. The sheath is shipped in an elongated, flexible bag (42) having a length substantially equal to the length of the insertion tube (12) of the endoscope and a diameter substantially larger than the diameter of the insertion tube. The sheath (22) and bag (42) may be shipped in a sterile tray (100) having a spiral recess (104) containing the sheath, bag and funnel-like container (60) or bag holding the tubing of the air, water, and suction channels. Installation of the sheath on the endoscope is accomplished by inflating the sheath while it is in the bag so that the sheath expands until it contacts the wall of the bag. The insertion tube is then inserted into the sheath, the sheath is deflated and the insertion tube and surrounding sheath are removed from the bag for use. After use, the insertion tube and surrounding sheath are inserted into the bag, and the sheath is inflated until it is restrained from further expansion by the wall of the bag. The insertion tube is then removed from the sheath, the sheath is deflated, and the sheath and surrounding bag are discarded as a unit, the funnel-like proximal segment being used to dispose of the contaminated tubes (air, water, suction, etc.).

Abstract: A film of a high-temperature superconductor (HTSC) is applied to a substrate (20) by pulverizing a target (15) of a material of a predetermined composition, and said film is given a structure and an oxygen stoichiometry suitable for superconductivity by heat treatment. Pulverizing according to said invention consists in sputtering by means of a magnetron (10) where the substrate (20) forms with the target (15) an angle of 45 DEG  to 90 DEG . The surface of the substrate (20) is preferably perpendicular to the target (15) and the magnetron is preferably a planar DC-magnetron (10). In said conditions, texturized high-temperature superconducting films can be produced on polycrystalline substrates, the c-axis orientation of the film produced being advantageous for conductivity.

Abstract: Pressure sensors utilizing capacitance variations to sense pressure variations of the silicon-on-silicon type in which dielectric drift, which occurs in such sensors due to the changing characteristics primarily of the dielectric wall support layer (116) extending up from the silicon sub­strate (112) between it and the silicon diaphragm (111), is minimized by in turn minimizing the contribution of the dielectric layer to the total capacitance of the sensor (110), reducing the dielectric contribution to the capaci­tance from, for example, about fifty (50%) percent down to a range of no more than about twenty to twenty-five (20-­25%) percent and down typically to sixteen to about ten (16%-10%) percent of the total capacitance or lower. Three exemplary approaches are illustrated, namely, etching the outer edges (116A) of the dielectric layer, making the wall(s) it form(s) thinner (Fig. 2); reducing the horizontal thickness of the effective peripheral, lower edge(s) of the silicon diaphragm where it interfaces in contact with the wall(s) formed by the dielectric layer (Fig. 3); and/or reducing the horizontal thickness of the effective peripheral, upper edge(s) of the silicon base or substrate where it inter­faces with the wall(s) formed by the dielectric layer (Fig. 4); and/or a combination of one or more of these approaches or any other approach that minimizes the effective capacitive contribution of the peripheral dielectric layer to the total capacitance of the sensor and hence to long term drift.

Abstract: The method is usable in particular for the broadcasting of HD-MAC programmes. The source-image analysis signal is subjected to a space- time undersampling and to a nonlinear motion compensation filtering, leading to transmission over at least two successive transmission frames (t1, t2) of the points representing a same source image, and to transmission, at the same time as the image, of auxiliary data defining a motion vector field. To improve the compatible image furnished by a first generation receiver, the second analysis frame corresponding to a same source image is subjected to a temporal attenuation in the direction of the motion. This attenuation depends on the motion vector and leads to allocating to each point of the said parts a position (C) intermediate between its position (A) in the analysed source image and its anticipated position (B) in the direction of the motion. …<IMAGE>…

Abstract: An apparatus for use in measuring the straightness of a tube includes a flat support surface made of electrically insulative material and a plurality of strips of electrically conductive material oriented parallel to one another on the support surface. The strips are substantially uniform in shape and thickness, and a layer of dielectric material covers each of the strips of conductive material. The layers of dielectric material are of uniform thickness along the length of the strips and are adapted to support a tube to be tested for straightness so that a capacitor is formed by each of the strips and the tube. An oscillators is provided for generating pulses each having a pulse width proportional to the capacitance between at least one of the strips and the tube and representative of the size of gap between the at least one strip and the tube. These pulse widths are measured and compared with a preset value representative of a limit pulse width in order to determine the acceptability of the tube straightness. A method of measuring the straight­ness of a tube by measuring capacitances along the length of the tube as it rolls along a support surface is also disclosed.
