Abstract: The visibility determination process uses fixed-position picture characteristics on an original picture. Vertical fixed reference points (P) e.g. roadside reflectors or road markings approximately in line with one another radially with an emergence point (E) are chosen. These are picked up by a detector on a CCD camera to give a first image (P), and electronically transposed to a second frame (P') of the film. Non-fixed points (N) e.g. other vehicles are recognised in that they do not generate displacement vectors radial with the emergence point. Through the resulting displacement vector (P-P') and knowledge of parameters relating to the movement of the motor vehicle, the distance of the reference points from the receiver can be assessed. At the last stage in the process the distances of the marked points with regard to a maximum distance can be filtered to give a measure of the visibility, by making a comparison of corresp. points on the two the images via grey scales, using a fuzzy logic system.

Abstract: For welding tube socket joints in thermoplastic tubing, where the straight end of one tube is inserted into the socket end of the next tube section, heat is applied to melt the thermoplastic material together with a pressure to bond the sections together. The pressure is set to give a structured joint pressure, where there is a defined pressing action on the outer circumference of the inserted tube end against the inner circumference of the surrounding socket of the other tube end, before the welding action develops. The pressure is continued until the material has cooled after the welding stage.

Abstract: A logic circuit arrangement for performing synchronous dual word decoding utilizing a programmable logic array which is formed with a reduced number of transistor counts. This is achieved by organizing the AND plane (64) so as to decode only the seven (7) most significant bits of an 8-bit opcode word. A LSB decoder circuit (153) is used for decoding the least significant bit of the opcode word separately and outside of the AND plane. As a result, the amount I.C. chip space required has been substantially reduced.

Abstract: A deflecting tool or whipstock is oriented and anchored in a well casing during a single trip of a running string so that a window can be formed in the wall of the casing at a selected azimuth. The angular orientation of the deflecting tool is measured, and signals representative thereof are transmitted to the surface. When the desired orientation is obtained, the anchor is actuated to prevent movement of the deflecting tool, and the orientation adjusting and measurement and transmission tools are released from the whipstock and removed from the casing by withdrawing the running string which preferably is coiled tubing. Then a downhole motor and milling bit are run into the casing on coiled tubing and operated to form a window through the wall thereof opposite the deflection surface of the whipstock so that a new borehole can be drilled outside the casing.

Title: Overvoltage protector
Inventor: GERLACH HORST
IPC: H02H9/04
Filed: 1995-01-24
Abstract: In traction current systems, parts of the system are operated at different potentials. At locations where the difference in potential can assume unacceptable values, it must be possible to equalize the potentials temporarily in order to protect against dangerous shock currents and to protect parts of the system. This protection can be brought about by overvoltage protectors or short-circuiters. The overvoltage protector according to the invention is connected by its terminals (9, 10) to the different potential planes. Through a series circuit comprising a varistor (2), a resistor (3) and a coil (5) flows an equalizing current which momentarily suppresses any overvoltages occurring and, owing to the voltage drop at the resistor (3), triggers a thryistor (4) which takes over the equalizing current. If the equalizing current exceeds a preset value, a short-circuit contact (6) is closed and short-circuits the two potential planes. If the difference in potential drops to an acceptable extent, potential separation is re-established. The proposed overvoltage protector operates non-directionally through its four diodes (1.1 to 1.4). It can be used wherever temporary potential equalization has to be ensured between different potential planes. The respective state is detected and can be signalled via the potential-free contacts (6.2, 8.1).

Cette énergie vibratoire est évacuée loin des enceintes acoustiques (41, 90, 96, 97) ou de tout autre corps et dissipée sous forme de chaleur, dégagée par la structure moléculaire interne de la matière visco-élastique, ce qui a pour effet de supprimer le bruit normalement produit par le corps vibrant. Dans diverses réalisations, le dispositif amortisseur de vibrations comprend des plaques d'amortissement façonnées et montées de manière à atténuer une large bande de fréquences de vibration. Les plaques amortisseuses elles-mêmes peuvent avoir chacune une configuration avec une caractéristique de fréquence variant en permanence sur toute la longueur ou sur toute la circonférence de la plaque; on peut intégrer plusieurs plaques de tailles différentes, correspondant chacune à une bande de fréquences différente.

Abstract: A transmitted high definition television signal is represented by a packetized datastream configured as a sequence of data fields (fig. 1) with a non-uniform data rate due to different types of different duration non-data overhead information. Each data field is prefaced by a Field Sync overhead segment followed by 312 packetized data segments each with associated overhead information (FEC). At a transmitter (fig. 4), a transport processor (14) forms data packets with associated headers and exhibits uninterrupted operation at a constant uniform data rate, while supplying a packetized datastream to a network (17) which constructs sequential data fields by inserting the non-data overhead information into the datastream. The transport processor is advantageously operated at a constant uniform data rate without having to modify the original data field structure to accommodate the needs of the data field construction network. This result is facilitated by transferring data from the transport processor to an associated interface/buffer network (46) in response to a 3/8 symbol clock, in combination with a predetermined buffer fullness level. A counterpart transport processor/decoder (86) at a receiver (fig. 17) coacts with a data field processor (75) and similarly exhibits uninterrupted operation at a constant uniform data rate.

Abstract: The present invention concerns a microscopic electromagnetic radiation transmitter or detector and a so-called near field probe (1) whose body takes the form of a polyhedron point and consists of a material which is at least partially permeable to electromagnetic radiation in the spectral region used. The polyhedron point is delimited by an imaginary base surface beyond which the substantial part of the body is continued to form a total probe body, which is not defined in greater detail. The polyhedron point has n side faces and edges leading to an acute point (2) are formed between adjacent side faces. According to the invention, at least two side faces of the body of the polyhedron probe (1) are coated with thin, electrically conductive layers which absorb some of the electromagnetic radiation in the spectral region used, preferably consist of materials such as aluminium, gold or silver and are less than 0.2  mu m thick. The front part of the polyhedron point (2) is also coated with the material used, resulting in an efficient near field probe with comparatively high resolution in optical near field scanning microscopy, simultaneous scanning tunnel microscopy also being possible with the same point.

Abstract: Un signal (50) bruité obtenu à partir d'un système d'acquisition (21) tel qu'un microscope classique ou confocal, est amélioré d'une manière qui permet l'estimation simultanée du signal vrai ou idéal ainsi que la fonction de réponse du système d'acquisition. Le signal restauré peut être une fonction d'une ou plusieurs variables, par ex. le temps ou l'espace. Une connaissance préalable de la fonction de réponse du système d'acquisition n'est pas nécessaire, ce qui élimine le besoin d'étalonner ledit système d'acquisition (21) avant l'acquisition d'un signal. Le signal vrai et la fonction de réponse du système d'acquisition sont estimés de manière itérative. Les données de signal effectives et le contenu relatif à la fréquence des données de signal effectives peuvent être utilisés pour déterminer les contraintes à appliquer aux estimations du signal vrai et à la réponse impulsionnelle du système d'acquisition. Lesdites contraintes incluent des contraintes sur le signal (dans le domaine de l'espace) (54) et des contraintes dans le domaine des fréquences (58).
