Abstract: The present invention provides an organohydrogenpolysiloxane which does not have an average chemical structure as encountered with organopolysiloxanes prepared by equilibration polymerization reactions, but rather which has a clear, defined chemical structure in which the position and number of silicon-bonded hydrogen groups is clearly defined. The organopolysiloxane has a branched structure in the vicinity of one terminal of the molecular chain and has the silicon-bonded hydrogen group at each of the resulting derivative terminals. The organopolysiloxanes can be addition-reacted with, for example, organic compounds having various functional groups to give organopolysiloxane having two organofunctional groups clustered at one terminal.

Abstract: The present invention is directed to filtering out unwanted components contained in acquired sonic well logging data, e.g., reflected wave components, converted wave components, casing arrivals, tool arrivals and/or noise. In the filtering method, the waveform components of each waveform are treated as vectors, each vector having n samples. The vectors, described in n-dimensional space, are rotated to a new coordinate system whose directions, characterized as eigenvectors, are aligned with the primary directions of the wave component vectors. The eigenvectors are ordered such that the first eigenvector represents the wave components' main direction, the second eigenvector represents the wave components' next main direction, et cetera. By projecting the waveform components onto the principle eigenvectors, the reflected wave components, converted wave components and/or noise component of each waveform is substantially eliminated. Methods are also disclosed for approximating the eigenvectors. The present invention is further directed to estimating a reflection coefficient of a bed boundary in the formation, identifying the lithology of the formation traversing the borehole, and compressing the sonic data, based in some manner on the obtained eigenvectors or their approximations.

Abstract: A well logging system includes a digital threshold crossing data generation system (TCDG System) disposed in a well tool, adapted to be disposed in a borehole, and a digital first motion detection (DFMD) software disposed in a memory of a well truck computer. The TCDG system generates a series of threshold crossings for each analog signal received from a receiver of the well tool, the threshold crossings including a plurality of threshold crossing events for each analog signal and representing compressed versions of digitized analog waveforms. The well logging truck computer receives the threshold crossing data from the TCDG system and executes the DFMD software. When the software is executed, a first set of compressional wave first arrival times are determined from a startup routine in the software using the threshold crossing data. A second set of compressional wave first arrival times are determined from a tracking routine in the software using four different prediction methods and a voting procedure to select the second set of arrival times from among the four predictions. A cycle skip detection routine in the software determines if any cycle skips are associated with either the first or second set of compressional first arrival times. Finally, a cycle skip recovery routine determines which set of compressional first arrival times to select depending upon the outcome of the cycle skip detection routine.

Abstract: A method and system is disclosed for fuzzy inference parameter adjustment in a fuzzy inference system for obtaining an output value by a node from at least one input value in a calculation network having a plurality of nodes for calculating the output value from at least one input value in predetermined procedures and at least link for connection between the nodes, and for obtaining a fuzzy inference output value with use of the calculation network by inputting an output value of a node to another node through the link for the node and by successively repeating similar input-output conversion as necessary. 
     The system can trace back a cause of error of the inference output value from a teacher data on the calculation network to adjust each fuzzy inference parameter, thereby providing a highly accurate and highly efficient inference. 
     The system learns input-output relationships between pluralities of sets of inputs and outputs expected in advance, and obtains a value by differentiating or finite differencing a difference of an output value to an input from an expected output value with respect to the parameter for each of the sets of the inputs and the outputs, thereby being capable of indicating high order statistical value of dispersion and the like for each pair of input and output and indicating distribution of differentiated or infinite difference calculated values.

Abstract: A pulse-width modulated (PWM) circuit applies a voltage across a load (32) in accordance with a PWM command signal (I). The command signal (I) is converted into first and second trains of pulses (x, x'), by electronically comparing the command signal with a triangular dither signal (D) and also with the dither signal which has been shifted by half its period. These two pulse trains, and two more pulse trains (y, y) obtained by taking the complements of the original pulse trains, are applied to a pair of bridge circuits (A, B). The load (32) is connected to both bridge circuits. Both bridge circuits are configured such that when a pulse is present, from either the first or the second pulse train, no net voltage appears across the load. At all other times, substantially the entire power supply voltage is applied across the load. In another embodiment, n pairs of bridge circuits are connected across the load. The pulse trains are generated using dither signals which are shifted in time. The pulse trains of one pair of bridge circuits are shifted from the next pair by t/2n, where t is the period of the dither signal. The greater n, the less the effective ripple current in the load. The invention is especially suitable for use in controlling gradient coils in a magnetic resonance imaging system.
