A device for calculating 3D seismic classification features constrained to be tangent to a path in a 3D volume is provided as a “geo-operator”. The method has the capability to associate horizontal (2D), vertical (2D) or arbitrary (3D) classification “feature vectors” with the geo-operator output, to allow determining where the geo-operator has sufficient data for the calculation to form a valid output and where the output of the geo-operator indicates a measure to which alternative feature vector prototypes may be present along the path. The geo-operator has the flexibility of using variable crossline, inline and vertical extent and having a direction able to be designated as it traverses the path, from the start point to the endpoint, aligned to be tangent to the path.

A method and apparatus is disclosed, particularly, though by no means exclusively, useful in touch-screen computer CRT display systems and the like, and more generally in other force and/or torque measurement systems, as in weighing and the like, in which (1) lineal and/or rotational acceleration of the system is sensed in response to inertial interference effects such as tilt or movement that introduce errors into the force and/or torque measurements, and/or (2) inertial error correction from the force data itself is obtained, such as derivative order corrections; and such data is used to correct the force and/or torque measurements. A novel calibration technique for deriving appropriately descriptive coefficients to the particular system for the correcting data, is also disclosed.

The invention relates to a base matrix, a encoder/decoder of Low Density Parity Check (LDPC) codes and a generation method thereof. The encoder/decoder is determined uniquely by the parity check matrix of the LDPC codes. With different code sizes, said parity check matrix can be obtained by expanding different base matrixes, and also can be obtained by expanding a unique base matrix after correction. Elements of said base matrix must meet an inequation in which the girth value is up to the standard, e.g. when girth ≧6, for any element i, j, k, l in the matrix which forms the short loop having a length of 4 in anticlockwise, there are always mod(i−j+k−l, z) unequal to 0. By this invention, the girth of the constructed base matrix is made as large as possible, the amount of the shortest loops is as few as possible when it is the same girth, thus the curve of bit error ratio (BER) is dropped quickly, the error floor of the LDPC codes is eliminated effectively, and the optimal performance of the LDPC codes is obtained.

The invention relates to a method for eliminating error elements caused by movements of an imaged object in X-radiography, said method comprising performing X-radiography on an imaged object for compiling three-dimensional X-radiographic information. The method comprises creating a model geometry of an X-ray imaging process, said creation work comprising a determination of the location for two or more position markers in a set of coordinates graded for an X-ray imaging apparatus. When X-radiography of an imaged object is completed, predictions are worked out regarding the locations of position markers during the imaging session. The locations and predictions determined on the basis of the model geometry are used as a basis for defining projected or most likely locations for the position markers and an automatic position markers identification method is applied for finding the locations of position markers from within a search area in the X-radiographic information. When the locations of at least two position markers have been found with the automatic position markers identification method, a minimization of offsets between the projected locations of position markers and the locations of position markers looked up by the automatic identification method is performed by searching for a minimum point of the function for eliminating the error elements resulting from movements of an imaged object.

Techniques for detection of impending data errors in a mass storage system, such as a track squeeze problem in an electromagnetic disk drive, and then repairing the impending problem, such as by rewriting the affected tracks. In many cases the problem is detected and repair is effected when the original data can still be read. In other cases, when the data is no longer readable on the disk in question, but when the disk is part of a Redundant Array of Independent Disks (RAID) system, or other system in which higher layer fault tolerance mechanisms are implemented, the missing data can be recovered via these mechanisms. The recovered data is then used to repair the track squeeze problem. The invention can be implemented as firmware in a storage system, as a component of a general purpose operating system, or inside individual disk drives, or it can use a combination of these implementations.

A method for writing streaming audiovisual data to a disk drive is performed by organizing the data into clusters and commencing writing the clusters to the first physical sector encountered after the read/write head has settled to the desired track on the rotating disk. A cluster contains a number of data blocks corresponding to the number of physical sectors in an integer number of tracks on the disk, so that the writing of a single cluster is the writing to an integer number of full tracks on the disk. Even though the disk drive may have a physical index to identify the first physical sector in all the tracks, the writing of cluster data takes place without regard to index position. During interleaving of audiovisual data, when multiple recording tasks are cycled until all the tasks are completed, the clusters in the first portion of the first task are written during the first interleave period, the head is then positioned to another track where the clusters in the first portion of the second task are written during the next interleave period, beginning with the first physical sector encountered by the head, again without waiting for index. The location where the first block of cluster data has been written is identified by writing a block number into the physical sector or by writing a start of cluster indicator on the track where the cluster is written.

Eye diagrams are made for signals on each channel in a group thereof. Outlying signals that do not exhibit overlap for a sampling parameter that is to be common for all channels may be ignored and a warning given. Selected, normalized eye openings are used to discover optimum sampling parameters for each channel. Locations within each eye opening are ranked according to preference. Algorithms are used to select a single best value for a sampling parameter common to all the channels, and the corresponding best other sampling parameter is found for each channel. One algorithm disregards good choices for many channels to accommodate any remaining channel by using only a commonly agreed upon value (a jury system). Another algorithm gives weight to a choice according to the number of channels that agree on that choice (majority rule). A graphical user interface facilitates the selection, and emphasizes which sampling parameters are constrained to vary together.

The invention relates to phase matched optical gratings for performing signal multiplexing and demultiplexing in optical communications networks. In prior art gratings there is a phase linearity error between the grating line and the outputs on the focal line, comparing the center output to the surrounding outputs. This corresponds to a relative phase difference between each output which limits the passband. In the case of the AWG this degradation comes primarily from field aberrations in the output star coupler. The present invention has found that if the grating line of the optical grating is disposed on a ellipse instead of a circular arc, while the focal line of outputs defines a substantially circular arc, an optimum can be found where the phase linearity error is substantially eliminated, and all outputs have substantially the same phase. As a result, this creates substantially uniform passbands across the WDM spectrum.

In an error correction device, a frame generation section receives pulse signals as temperature information of a power switching element transmitted from a PWM comparator. The frame generation section sets a first correction pulse signal, a second correction pulse signal and the temperature information sequentially into each frame. A pulse width of the first correction pulse signal corresponds to a pulse width when a time ratio thereof becomes 100%. A pulse width of the second correction pulse signal corresponds to a pulse width when a time ratio thereof becomes 50%. A microcomputer receives the temperature information through a photocoupler and corrects the received temperature information. The microcomputer calculates a temperature detection value of the power switching element on the basis of the corrected temperature information.
