Abstract: The voltage transformer (8) which can be used in a medium- or high-voltage system exhibits an ohmic voltage divider (12), which is of rotationally symmetric shape, as voltage sensor. This voltage sensor can be brought into contact with a voltage-conducting part and with a part which is at earth potential of the system. The voltage transformer (8) is intended to be distinguished by high measuring accuracy even under the most varied operating conditions of the system containing it. This is achieved by the fact that the voltage sensor constructed as voltage divider (12), after being installed in the system, is arranged in a space (22) which is largely shielded against electrical fields. <IMAGE>

Abstract: A process for conditioning air by adjusting its temperature (cold/hot operation) and/or humidity (climatic operation) in a closable space (10) such as an air-conditioning testing cupboard is proposed, which comprises heating, cooling and circulating aggregates (16, 18, 20, 22) as well as a hydraulic seal (26). In this connection, the cooling aggregate is, during cold/hot operation, acted upon with a liquid first cooling fluid in the form of a refrigerating agent which is evaporated in the cooling aggregate and, during climatic operation, with a liquid second cooling fluid. In order to avoid condensate formation, which would distort the conditions in the air-conditioning cupboard, it is proposed that the second cooling fluid is a or the refrigerating agent which is evaporated in the cooling aggregate, gaseous refrigerating agent being added to the cooling agent before entering the cooling aggregate (16). The invention also relates to further developments of a testing cupboard (14) and of a control desk. <IMAGE>

Abstract: Surveillance radar for distinguishing wanted moving targets from unwanted moving targets by processing radar target return data has prestored evaluation criteria for accepting/rejecting the moving targets. The radar target return signals are passed by a receiver/exciter (40) to a digital signal processor (42) that outputs signals representative of ambiguous radial velocities of targets, signal-to-noise ratio, and range to a radar data processor (44). A true radial velocity estimator (22) and an apparent radar cross section estimator (24) of the radar data processor (44) determine the true radial velocity and apparent radar cross section. In the processor (44), a computer (26) evaluates these measurements based on a look-up table of preselected acceptable levels of minimum true radial velocity for each apparent radar cross section. The computer (26) declares a target acceptable when its radial velocity matches or exceeds the preselected minimum radial velocity for that radar cross section stored in memory. The acceptance criteria relates to the type of target (aircraft, missile, bird, etc.) being accepted or rejected. In general, the criteria accept large targets having low to high radial velocities. The smaller the apparent radar cross section of the target, the higher the true radial velocity must be for acceptance. The true radial velocity versus apparent radar cross section profile is intended to accept aircraft and missiles but reject birds.

Abstract: This invention consists of methods for the detection of nucleotide-binding compounds in complex fluid mixtures. The invention consists of fixing a target polynucleotide of known sequence to a non-porous support which comprises or is contained within a container. The challenging sample fluid is then introduced in such a way that compounds present in the fluid bind to the target polynucleotide. This binding blocks the hybridization of a second, complementary polynucleotide to which is attached a label comprising a moiety capable of generating a detectable signal. The invention further provides for indirect means of binding the target polynucleotide to the support and of generating the detectable signal.

Abstract: The pitch based carbon fiber has a uniform crystal structure in which substantially all crystal fibriles constituting the fiber have the thickness ranging from 30 to 200 % of the average thickness Lav. Uniform stress distribution over uniform crystal fibriles can be obtained. This permits suppresion of non-linearity of the compressive modulus of elasticity of carbon fiber to greatly improve the compressive strength thereof. Typically, a compressive strength of 100 to 170 kg/mm² can be obtained with a tensile modulus of elasticity of 50 ton/mm². Such carbon fiber can be obtained by securing uniformity of molecular weight distribution of the liquid crystal pitch and also uniformity of the orientation of the liquid crystal constituent molecules by the application of multi-stage high shear spinning.

Abstract: A handwritten test symbol (51), such as an alphabetic character, a word or a signature, written on a digitizing tablet is normalized by comparison with a model symbol (52a, 52f, 52h) to determine the transformation necessary to best fit the test symbol to the model symbol. Such transformation is then applied to normalize the test symbol (54a, 54f, 54h). Shape information in the test symbol is preserved during such normalization. In one form of the invention, the model symbol is a line segment. In another form of the invention, the model symbol is an example of the symbol being normalized. Such normalization can be used as a preprocessing step in applications such as character recognition, text recognition or signature verification.

Abstract: Disclosed is a method and system for providing communications services between multiple processes running in multiple computer systems. A mechanism of creating logical process hierarchies within a distributed environment is provided. Extensions beyond the logical process hierarchy are similarly provided. The communication mechanism is implemented as a library of functions available for use by individual processes. An arbitrary definition of context may be used, such that processes need not be related within the operating system process space by name or any other attribute. Rather, a single system semantic can be used to access processes, whether such processes reside on a local or remote computer. A mechanism is provided to allow processes to register as part of a distributed context. Registration may be accomplished explicitly by any child process to name it's parent in the hierarchy, or automatically by the parent process when spawning children. This mechanism allows the additional flexibility that destination nodes in the distributed environment may be selected at run time without requiring knowledge on the part of the executing process. This allows the ability to cause processes to be distributed based on machine type, facilities available on a specific node or load balancing considerations. This registration mechanism is expandable to allow general purpose server implementations in a distributed environment, thus providing to the user system transparent facilities for control in a distributed environment.

Abstract: Oxygen is separated from air by means of a high temperature ion transport membrane which is integrated with a gas turbine system for energy recovery from the membrane nonpermeate stream. Air is compressed, heated in a first heating step, and passed through the feed side of a mixed conductor membrane zone to produce a high purity oxygen product on the permeate side of the membrane zone. Nonpermeate gas from the membrane zone is heated in a second heating step and passed through a hot gas turbine for power recovery. The operating temperatures of the membrane zone and the expansion turbine are independently maintained by controlling the rate of heat addition in the first and second heating steps, whereby the membrane zone and expansion turbine are thermally delinked for maximum oxygen recovery efficiency.

Abstract: A receiver for decoding N received branchword signals is disclosed. Illustratively, the branchword signals are generated by a tailbiting convolutional coder. The receiver stores received branchword signals in memory such that the branchword signals are accessible in a logically circular sequence. The receiver then performs Viterbi updates on the logically circular sequence of branchwords, the sequence comprising more than N branchwords. Each Viterbi update provides a decision vector. The receiver stops performing Viterbi updates in response to an indication that Viterbi update decisions have become repetitive. A set of generated decision vectors resulting from the Viterbi updates is then modified in response to the indication. A decoded signal is generated by performing a Viterbi traceback procedure using the modified set of decision vectors. The indication that Viterbi update decisions have become repetitive may be provided by a predetermined fixed number of Viterbi updates, the number reflecting an estimate of when said update decisions will likely become repetitive. The indication may also be provided by a comparison of decision vectors generated by Viterbi updates on the same stored branchword to determine whether the vectors are substantially equal. Or, the indication may be provided by a comparison of a pair of path metric vectors generated by Viterbi updates on the same stored branchword to determine whether differences between metric signals of one or more respective trellis state pairs of the path metric vectors are substantially equal. Modification of the set of generated decision vectors may include replacing a one or more decision vectors of the set with one or more later-determined decision vectors of the set. Alternatively, such modification may include extending the set of decision vectors by repeating previously determined decision vectors of the set.
