Abstract: A computerized simulation validating method for a full-scale distribution network single phase-to-ground fault test is implemented by simulating a full-scale test system with external quantities being controlled to be conformant and validating the full-scale distribution network single phase-to-ground fault test based on a conformance check result between the internal quantities of the field testing and the internal quantities of the simulation testing. The simulation validating method for a full-scale distribution network single phase-to-ground fault test improves normalization and conformance of the full-scale distribution network ground fault test. The computerized simulation validating system, apparatus, and medium for a full-scale distribution network single phase-to-ground fault test also achieve the benefits noted above.

Abstract: A method, apparatus and decoder for decoding cyclic code are proposed. The decoding method comprises: receiving a transmitted cyclic code; calculating the initial syndrome of the cyclic code; by using the initial syndrome and w prestored successive shift operators, calculating respectively w successive shift syndromes in a w-bit window of the cyclic code in parallel; and detecting/locating error in the cyclic code based on the obtained syndromes. The decoding apparatus corresponds to the above method. And the corresponding decoder is also proposed in this invention. The method, apparatus and decoder according to the invention could process the cyclic code within a window width and thus enhance decoding efficiency in parallel.

Abstract: Techniques for scanning an object that does not fit upon a scan surface of a scanner and requires a non-linear scanning path are described. In one embodiment, a pair of optical navigation sensors and an image sensor (e.g., CIS) are used to determine coordinates and an angle of a scanning object. By acquiring the coordinates of optical navigation sensors with respect to the image sensor after each relative movement between the image sensor and the scanning object, coordinates of pixel points on the image sensor can be readily determined as long as there is a predefined geometry between the optical navigation sensors and the image sensor. In addition, scanned image data can be modified, enhanced or corrected in scanning or in memory.
