Abstract: A 2D image supplied from an image input unit including a wide view lens is sampled into a discrete form by an array sensor, and then mapped to a multi-resolution space by a 2D filter.  The feature of the supplied image is detected, and then the mapped image is transformed to a local pattern about the detected feature, and then the coordinates of the position of the feature and the code word of the local pattern are formed into a set which is then encoded.  The code is supplied to each cell of a stochastic automaton.  The quantity of visual information is calculated in accordance with the quantity of mutual information between different cells of the stochastic automaton consisting of cells in blocks, the coordinates of the position of the feature and the distance from the feature to the optical axis so as to control the optical axis of the image input unit in such a manner that the quantity of visual information is maximized.

Title: Linked gaming machines having a common feature controller
Inventor: PIECHOWIAK ROBERT J
IPC: G07F17/32
Filed: 1995-02-21
Abstract: The preferred embodiment of the present invention operates on a system of interconnected gaming machines. In a normal operation mode, the individual machines provide awards to individual players based on the generation of symbol combinations in a first group of symbol combinations. The linked gaming machines are polled by a feature controller to determine whether symbol combinations in a second group of combinations are generated. These symbol combinations in the second group of combinations are accumulated until a level is reached such that a bonus award will be given to the next player whose machine generates a symbol combination within said second group of symbol combinations.  The first machine to generate a winning symbol combination within said second group of symbol combinations is given a bonus award. The feature is then reset. The status of the feature is displayed for all players of the linked gaming machines.

Filed: 1997-04-23
Abstract: An   intraluminal,   crush-resistant   stent   for implantation in a body lumen is disclosed.  The crush-resistant stent  is made  from a base section having a plurality of resilient,  parallel,   coplanar  struts  having  a  zig-zag configuration extending therefrom wherein the zig-zag struts are curved and pass through corresponding slots in the base section to form a continuous, cylindrical hoop.  Each zig-zag strut has an amplitude that decreases when the zig-zag strut is placed under tension and an amplitude that increases when the zig-zag strut is unstressed or is placed under compression. Accordingly,  each zig-zag strut can be pulled through the respective slot in the base section, but under compression the zig-zag struts assume the larger amplitude and cannot pass through the corresponding slot thereby maintaining the diameter of the stent constant.

Title: Separation of sulphides and chlorides from pulping liquors by electrodialysis
Inventor: PALEOLOGOU MICHAEL
IPC: B01D61/44
Filed: 1996-02-09
Abstract: A process using an electrodialysis system employing cation-selective membranes and anion-selective membranes, particularly monovalent anion-selective membranes, is used to separate kraft pulping liquors into two streams; one that is rich in sulphides (to be used in the initial stage of pulping), and another that is poor in sulphides (to be used in the final stage of pulping). By separating pulping liquors in this way, the sulphur balance in the kraft process can be maintained while obtaining the benefits of modified pulping. The same electrodialytic system can be used to separate green and polysulphide liquors into sulphide-rich and sulphide-poor components.

Title: Run-flat tire and method of manufacture
Inventor: SNIPES VIRGINIA W
IPC: B60C9/14
Filed: 1997-08-01
Abstract: ' The run-flat tire of this invention includes a pair of bead regions,  a crown region with a tread and a tread reinforcing package including a cap ply and self supporting sidewalls between each bead region and the crown region.  An innerliner ply maintains air within the inflated tire.   The self supporting sidewalls each include a first crescent-shaped reinforcing member, an inner carcass layer, an inner sidewall supporting complex and an outer sidewall and bead protecting complex.  The supporting sidewalls effectively have a plurality of crescent-shaped reinforcing members and a plurality of carcass layers.  The sidewall supporting complexes are realized by providing first and second partial carcass layers along with a  filler  rubber  portion  and  a  second  crescent-shaped reinforcing member, which can be formed by a separate tire building operation.  The sidewall protecting complexes can be formed in a similar operation.   The run-flat tire of this invention can be realized within standard production rates for building tires.           The inflated vs. deflated performance tradeoffs in ride comfort, handling, radial stiffness and endurance of the tire  are  substantially maintained with  improved  mass  and rolling resistance over previous run-flat tires.   This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and with a rim that can be used interchangeably with the standard tire.
