Abstract: A coin validator has a thickness sensor formed by two coils positioned one on each side of the coin path. The coil outputs are processed separately to derive values which, when combined, produce a thickness-indicating measurement which is independent of coin position. Each output may be processed to give values which are linearly dependent upon coin position with the same constant of proportionality. Alternatively, one output is scaled relative to the other to an extent dependent upon the thickness for which the coin is to be tested, so that the thickness-indicating measurement does not vary significantly over a region which corresponds to a likely maximum variation in the position of coins of that thickness.

Abstract: Method and composition for detecting one or more selected polynucleotide regions in a target polynucleotide. In one embodiment of the invention, a plurality of different-sequence probe pairs are added to a target polynucleotide, where each probe pair includes two polynucleotide probe elements which are complementary in sequence to adjacent portions of a selected one of the target sequences in the target polynucleotide. In each probe pair, one of the probe elements contains a non-polynucleotide polymer chain which imparts a distinctive mobility to the associated probe pair, when the elements in the pair are ligated. The other element in the pair contains a detectable reporter label. After the probe pairs have been allowed to hybridize with the target polynucleotide, the hybridized polynucleotides are treated under conditions effective to ligate the end subunits of target-bound probe elements when their end subunits are base-paired with adjacent target bases. The ligated probe pairs are then released from the target polynucleotide and separated electrophoretically in a sieving matrix, or chromatographically.

Abstract: A cross-connect for a multi-ring, multi-channel telecommunications network, especially for a wavelength-division multiplexed (WDM) optical network. Each of the interconnected rings is self-healing by provision of a redundant counter-rotating ring or excess capacity on pairs of counter-rotating rings. Because an interconnect between self-healing rings does not need to connect working to protection fibers, or similarly redundant fibers, the complexity of the interconnect can be substantially reduced. For several important architectures, the interconnect can be decomposed into one or two 3x3 interconnects. Further, a wide-sense non-blocking 3x3 interconnect can be advantageously implemented as four 2x2 switches, which may be a basic building block of optical switches. A novel algorithm is available to add new paths through such a 3x3 interconnect. The interconnect can be decomposed into one or two 4x4 interconnects when another pair of add/drop lines are added. Such an architecture provides full connectivity between user nodes connected to the add/drop lines and user nodes attached to the rings.
