Abstract: A coupon redemption card and tracking system includes a credit card size redemption coupon card used by the customer,  and a tracking sheet used by the redemption center such as a restaurant.          The redemption card has a plurality of mini coupons, which can be peeled off individually. Each redeemed coupon is affixed to the tracking sheet, which has dimensions of a dollar bill so that it can be placed in the till of a cash register.  The tracking system facilitates the accounting and inventory of redeemed coupons.  The coupon card is formed as two laminated layers of special paper joined together by a layer of adhesive material, and a layer of clear plastic film on the top face of the card. The base layer is fabricated from a special paper. An adhesive coating is applied to one side of the base layer. The peel off coupon layer is affixed to the adhesive coating. The finished layered sheet is printed on both sides, die-cut on the coupon side, and then laminated with the film on the other side. Each coupon that is removed from the card has adhesive to adhere the coupon to the tracking sheet. The small size of the mini coupons is convenient for the card holder and the redemption center. It eliminates the need to process diverse sizes and shapes of customer coupons.  The system can be used wherever one has to keep track of various redeemable coupons.

Abstract: In a cellular radio communication system, a downlink signal is multicast from a cental station and multiple base stations receive the multicast downlink signal via transmission links and respectively transmit the downlink signal on radio waves of same frequencies so that a cluster of adjoining areas is illuminated with the radio waves. A mobile station having a tapped-delay line equalizer receives signals from the base stations via multipath fading channels and equalizes the received signals.      Interference between the transmitted signals is avoided by adjusting the relative propagation delay times of the transmission links so that the signals received by the mobile station occur within the tapped-delay line length of the equalizer.

Abstract: Using a sealing function the parent system seals the random number x which is generated by a random number generation means, and it, along with both the sealing function and the result calculation function, is made public by a setting publication means.  Each of the subsystems (i ) which will participate in the lottery sends the random number, which is a response, generated by its random number generation means.  The result calculation means of the parent system calculates a lottery result by applying the response ri and the initial value x to the result calculation function, and makes public the lottery result, the initial value x and the response ri.  Each of the child subsystems (i ) receives this information, and the result verification means determines whether the sealed initial value equals to the value calculated by applying the initial value to the sealing function, and whether the response of each of the child subsystems is recorded, and whether the lottery result equals the value calculated by applying the result calculation function to the initial value x and the response ri.
