Abstract: When an interpreter on a client computer encounters a symbolic reference to a remotely stored method while interpreting a locally stored method, and the object class for the remotely stored method has not previously been loaded, the client computer, the client computer creates an application specific loader that is then used to load the remotely stored method into the client computer. The application specific class loader contains location information associated with the server computer on which the remotely stored method is stored, and also contains methods for loading onto the client computer the object class for the remotely stored method as well as the object classes for any additional methods referenced by that method. The application specific class loader preferably also includes symbol table for storing information about method references that have been resolved by the application specific class loader.

Abstract: A color correcting device effects color correction of designated color digital data (DMAIN0-DMAIN7) in consideration of two of reference color digital data (Din10-Din17, Din20-Din27). The designated color digital data is data of a designated one of three primary colors. The two of the reference color digital data are data of remaining two of the three primary colors. A first memory (43, 61-63) stores auxiliary data (DSUB0-DSUB9) of which an address is a respective combination of the two of the reference color digital data. A second memory (44, 64-66) stores corrected data (DiOUT0-DiOUT7) of the designated color, an address of the corrected data being a respective combination of the auxiliary data and the designated color digital data. A read controller (32) provides the first memory with the two of the reference color digital data, and provides the second memory with the auxiliary data read from the first memory and the designated color digital data, to read the corrected data of the designated color.

Abstract: In a final wafer sort (FWS) testing facility, the raw log-out data that is output by FWS test stations is augmented with additional differentiating data to thereby produce differentiable log-outs that can be sorted according to a variety of criteria including: product number or product family, time of test, specific wafer, specific production lot, intra-reticle site number, machine operator, and the specific swappable units of equipment that participated in the FWS testing. The differentiable log-outs are stored in a database and are periodically accessed by an automatic watchdog system that tests for exception conditions calling for immediate or long-term response. Corresponding alarm signals and trend reports are automatically generated and distributed to responsible personnel and/or reactive machine-systems as appropriate. The alarm distribution mechanism includes automatic paging of personnel by wireless beeper and/or e-mail.

Abstract: A process for generating a direction signal indicating the direction of a short-circuit current in a power transmission line to be monitored. To reliably produce a direction signal even in the event of a short-circuit occurring in the proximity of the control point, each derived current and voltage signal (J.sub.R (t)) is separately sampled and normalized to obtain different normalized sample values (J.sub.Rn). Taking the triggering reference values (S.sub.n) into account, difference values (.DELTA.i.sub.R (t), .DELTA.i.sub.R (t-1), .DELTA.i.sub.R (t-2), .DELTA.i.sub.R (t-3)) are formed. The difference values (.DELTA.i.sub.R (t), .DELTA.i.sub.R (t-1), .DELTA.i.sub.R (t-2), .DELTA.i.sub.R (t-3)) of a series (S.sub.iR) are supplied to different input neurons of a suitably trained neural network successively and simultaneously with the difference values corresponding to the same times of the other series (S.sub.iS, S.sub.iT, S.sub.uR, S.sub.uT).

Abstract: A weight measuring apparatus comprising a plurality of load sensors, together with an input network, a multiplexer, a reference, an analog to digital converter, and a processor, wherein the input network includes an analog summing network and direct sensor connections to the multiplexer. The multiplexer is arranged to permit measurement of the sum signal, a reference signal, and each direct load sensor signal in a prescribed sequence. The multiplexed signals are converted to digital and processed to derive a weight estimate based on the multiplexed measurements and a system error model. The prescribed measurement sequence permits measurement of the sum signal more frequently than each of the direct signals. A method is described for deriving correction factors for the error model comprising the placing of calibration weights primarily on each weight sensor and solving the system of simultaneous equations for the resulting correction factors.

Abstract: Wave-number-frequency adaptive beamforming using a reduced rank k-.omega. matrix method. A spatial Fourier transform of the narrowband receiver outputs for the sensors in a linear array is taken to enter the wave number space and generate M independent spatial wave number beams w. The spatial FFT outputs are used to form the entries in a matrix of eigenvectors, wherein the k-th eigenvector represents a set of spatial convolution coefficients. The spatial wave number beams are weighted in an adaptation process by the spatial convolution coefficients to form a beam steered in the direction of a k-th signal source.

Abstract: A robust control apparatus for controlling an object corresponding to a robust control theory. A control model generating unit generates an object to be controlled, such as a dynamics model of a robot. In this model, both an error in each of the true values of coefficient matrices and noise are considered. When a corrected partial input of a selective partial input is considered, the generated dynamics model can be treated as a standard probability system model. When the partial input is optimized corresponding to the robust quadratic optimizing criterion, an optimized partial input can be obtained. The object is controlled corresponding to the optimized partial input and the output of the control model generating unit. Thus, in consideration of both the modeling error and the influence of the random disturbances, the robust quadratic optimization can be performed.

The sensors of the probe apparatus are zeroed by placing the probe apparatus in the only possible home position and assigning assumed starting angles to the sensors. A rotary table can be used to support the object being digitized, where the rotation of the rotary table and object during digitization is sensed and included in coordinate calculations.
