Abstract: A method and apparatus for decoding profiles which fail to resolve narrow elements in machine-readable symbols formed as relief patterns, first begins by identifying which elements in the profile are resolved. Second, the distances between the centers of the resolved elements are determined. Third, closure boundaries are determined, and the widths of resolved elements are determined at the closure boundary. The type of resolved element is determined based on its measured width. Thereafter, a unit distance is determined for 1-wide narrow elements unresolved in the profile. Based on the unit distance and the width of two adjacent resolved elements, a matrix is constructed for determining the number of narrow elements unresolved between two resolved elements. Based on the measured center distances, the resolved element widths and the matrix, all of the unresolved narrow elements are identified in the profile and the profile is subsequently decoded.
Abstract: An authentication method for a wired-logic microcircuit mounted on a support and a microcircuit reading terminal. The microcircuit is provided with a memory which has data readable by the terminal. A secret code of the microcircuit is arranged in a region of the memory that is not readable by the terminal. The microcircuit generates an authentication code from the data in the memory that is readable by the terminal, the secret code and a random code. The terminal generates an authentication code from the data in the microcircuit memory that is readable by the terminal, a secret code provided to the terminal by a microcircuit user and random code, and the authentication code generated by the microcircuit is compared with the authentication code generated by the terminal.

Abstract: A method and apparatus for calibrating detectors in a computed tomography (CT) system to compensate for differential errors in the detectors are disclosed. Multiple sets of scan data are acquired for a phantom at multiple thicknesses of the phantom. The phantom can be made from multiple slabs of material positioned on the scanner table in a horizontal orientation or in a vertical orientation. Horizontal slabs are removed or added to the stack of slabs to vary the thickness of the phantom. With vertically oriented slabs, each slab is of a different height such that scans of different slabs produce X-ray data for rays having different path lengths and, therefore, attenuations. For each detector, errors in the scan data at the multiple phantom thicknesses are identified and fit to a parametric equation with respect to the log attenuation associated with each thickness. In one embodiment, the parametric equation is a quadratic polynomial.

Abstract: A dot code recorded on an information recording medium consists of a data code corresponding to the contents of multimedia information to be reproduced, and a pattern code for determining a read reference point for the data code. The pattern code consists of pattern dots arranged at predetermined positions with respect to the data code, and markers arranged at predetermined positions with respect to the pattern dots and used to detect the pattern dots. In an information reproduction system for optically reading and reproducing a dot code from an information recording medium on which such a dot code is recorded, the dot code is imaged by an image input section. A data read reference point determining section then recognizes the pattern code from the picked-up image, and determines a data read reference point for reading the data code. A data reading section reads the data code on the basis of the data read reference point determined by the data read reference point determining section.
