A method and counter for reducing the background counting rate in gas-filled alpha particle counters wherein the counter is constructed in such a manner as to exaggerate the differences in the features in preamplifier pulses generated by collecting the charges in ionization tracks produced by alpha particles emanating from different regions within the counter and then using pulse feature analysis to recognize these differences and so discriminate between different regions of emanation. Thus alpha particles emitted from the sample can then be counted while those emitted from the counter components can be rejected, resulting in very low background counting rates even from large samples. In one embodiment, a multi-wire ionization chamber, different electric fields are created in different regions of the counter and the resultant difference in electron velocities during charge collection allow alpha particles from the sample and counter backwall to be distinguished. In a second embodiment, a parallel-plate ionization chamber, the counter dimensions are adjusted so that charge collection times are much longer for ionization tracks caused by sample source alpha particles than for those caused by anode source alpha particles. In both embodiments a guard electrode can be placed about the anode's perimeter and secondary pulse feature analysis performed on signal pulses output from a preamplifier attached to this guard electrode to further identify and reject alpha particles emanating from the counter's sidewalls in order to further lower the counter's background.

An electronic marker locator with a digital architecture for providing accurate and consistent estimation of the signal strength is presented. The marker locator includes a Digital Phase-Locked Loop (DPLL) structure. The electronic marker locator transmits known and adjustable frequency bursts corresponding to the markers to be located while synchronously capturing the signals returned from the markers. Because of the convergence properties of the DPLL, very consistent measurements of the reflected marker signal field strength are possible, resulting in both an improvement of maximum detection depth and depth accuracy. Further, the analog front-end hardware can be reduced, offering wider resistance to component tolerances, lower calibration and test times, and flexible frequency selectivity.

The present invention provides transgenic identification markers (TIMs) and methods of their use for identifying organisms and their progeny. TIMs are synthetically produced, heritable DNA molecules that, when inserted into cells of an individual organism, constitute a distinguishing, synthetic marker system for the organism. Because TIMs are heritable, upon cell division they are passed on to the progeny of the marked organism. TIMs thus provide a means of identifying and distinguishing such marked organisms and their progeny.

A compressive coding device converts three color components of pixel data from the RGB presentation to the YCbCr presentation according to a mapping rule. Converted pixel data are subsequently subjected to irreversible compressive coding, thus producing compressive coded data. Pixel data ascribed to transparency control are converted to a prescribed value out of a mapping range according to the mapping rule. Compressive coded data are supplied to a visual display control device, in which they are decoded and reproduced into original pixel data of the first color presentation. Compressive coded data corresponding to pixel data ascribed to transparency control are rendered with a prescribed color in the RGB presentation which is designated as transparency in advance or not rendered on screen. Thus, it is possible to precisely perform the transparency control without causing a reduction of the compression factor regardless of the irreversible compressive coding and decoding.

There is demand that discrimination of bills or securities by means of IC chip should be adopted. If the conveying speed of securities and banknotes is slowed down substantially by implementing discrimination by an IC chip, this gives rise to delays of the transaction process, which causes inconvenience to the user.
