12701 results about "Correction method" patented technology

Straightening. Another method for removing unbalance is to straighten or flatten a part along the axis of rotation. This type of correction is most commonly applied to long narrow parts such as spindles, driveshafts, and axels.

Multi-dimensional data protection and mirroring method for micro level data

The invention discloses a data validation, mirroring and error/erasure correction method for the dispersal and protection of one and two-dimensional data at the micro level for computer, communication and storage systems. Each of 256 possible 8-bit data bytes are mirrored with a unique 8-bit ECC byte. The ECC enables 8-bit burst and 4-bit random error detection plus 2-bit random error correction for each encoded data byte. With the data byte and ECC byte configured into a 4 bit×4 bit codeword array and dispersed in either row, column or both dimensions the method can perform dual 4-bit row and column erasure recovery. It is shown that for each codeword there are 12 possible combinations of row and column elements called couplets capable of mirroring the data byte. These byte level micro-mirrors outperform conventional mirroring in that each byte and its ECC mirror can self-detect and self-correct random errors and can recover all dual erasure combinations over four elements. Encoding at the byte quanta level maximizes application flexibility. Also disclosed are fast encode, decode and reconstruction methods via boolean logic, processor instructions and software table look-up with the intent to run at line and application speeds. The new error control method can augment ARQ algorithms and bring resiliency to system fabrics including routers and links previously limited to the recovery of transient errors. Image storage and storage over arrays of static devices can benefit from the two-dimensional capabilities. Applications with critical data integrity requirements can utilize the method for end-to-end protection and validation. An extra ECC byte per codeword extends both the resiliency and dimensionality.

Data hierarchy layout correction and verification method and apparatus

A method and apparatus for the correction of integrated circuit layouts for optical proximity effects which maintains the original true hierarchy of the original layout is provided. Also provided is a method and apparatus for the design rule checking of layouts which have been corrected for optical proximity effects. The OPC correction method comprises providing a hierarchically described integrated circuit layout as a first input, and a particular set of OPC correction criteria as a second input. The integrated circuit layout is then analyzed to identify features of the layout which meet the provided OPC correction criteria. After the areas on the mask which need correction have been identified, optical proximity correction data is generated in response to the particular set of correction criteria. Finally, a first program data is generated which stores the generated optical proximity correction data in a hierarchical structure that corresponds to the hierarchical structure of the integrated circuit layout. As the output correction data is maintained in true hierarchical format, layouts which are OPC corrected according to this method are able to be processed through conventional design rule checkers with no altering of the data.

Tooth brushing pattern analyzing/modifying device, method and system for interactively modifying tooth brushing behavior

Disclosed are a toothbrushing pattern analyzing/correcting device, a toothbrushing pattern analyzing/correcting method, a method and a system for interactively correcting toothbrushing behavior. The toothbrushing pattern analyzing/correcting device of the present invention includes: a body part formed in the same direction as a toothbrush surface; a sensing unit having a sensor with at least one or more axes for sensing a user's toothbrushing motion and a sensor with one or more axes for sensing two or more toothbrushing positions; and a controller for operating signals input from the sensing unit to classify a user's toothbrushing motion into at least two or more patterns and at least two or more toothbrushing parts. Further, the toothbrushing pattern analyzing/correcting method includes the steps of: detecting the start of a user's toothbrushing; displaying a guiding screen in response to the start of a user's toothbrushing; detecting a user's toothbrushing pattern; analyzing the user's detected toothbrushing pattern; and providing a toothbrushing correction screen with the intention of increasing compliance in accordance with the analyzed result. Accordingly, toothbrushing behavior correction compliance can be further enhanced with a method of interactively correcting a user's toothbrushing behavior through multimedia image substances in real time, and more systematic management and health consultation are possible by building a database of information of the user's toothbrushing behavior.

Binocular camera-based panoramic image splicing method

The invention provides a binocular camera-based panoramic image splicing method. According to the method, a binocular camera is arranged at a certain point of view in the space, the binocular camera completes photographing for once and obtains two fisheye images; a traditional algorithm is improved according to the defect of insufficient distortion correction capacity of a latitude-longitude correction method in a horizontal direction; corrected images are projected into the same coordinate system through using a spherical surface orthographic projection method, so that the fast correction of the fisheye images can be realized; feature points in an overlapping area of the two projected images are extracted based on an SIFT feature point detection method; the search strategy of a K-D tree is adopted to search Euclidean nearest neighbor distances of the feature points, so that feature point matching can be performed; an RANSAC (random sample consensus) algorithm is used to perform de-noising on the feature points and eliminate mismatching points, so that image splicing can be completed; and a linear fusion method is adopted to fuse spliced images, and therefore, color and scene change bluntness in an image transition area can be avoided.
