  • Patent number: 8051184
    Abstract: A method for pairing elements of a first set of elements {x(i)} with elements from a second set of elements {y(j)} subject to a plurality of pairing restrictions. In accordance with one embodiment of the method, for each of a plurality of iterations of the method, or until a set of pairings is found that satisfies the plurality of pairing restrictions, a random set of pairings between elements of the second set of elements and elements of the second set of elements is selected. The set of mismatched pairings is identified and, if the number of pairings in the set of mismatched pairings is not greater than a maximum number, pairings in the set of mismatched pairings are interchanged. If the number of pairings in the set of mismatched pairings is greater than one, each mismatched pairing is swapped with another pairing if the resulting pairings satisfy the plurality of pairing restrictions.

  • Patent number: 5209354
    Abstract: An improved reusable blister package is provided which consists of a base member, a top member and a label sheet. The top member mateably engages the opening of the base member. The label sheet seals the package shut after manufacture and prior to purchase. The package is opened by pulling the label sheet and the top member out and away from the base member thereby tearing the label sheet along the upper and side portions of the top member. The label sheet located along the lower end of the top member remains untorn and provides a hinge mechanism connecting the lower end of the top member to the lower end of peripheral flange of the base member. The improved package provides an outwardly facing label sheet that is entirely available for graphic presentations of logos and other product indicia.
