Inventor: FU IAN Y
IPC: A63F1/00
Filed: 1998-11-02
Abstract: A method of playing a Big Ten card game which is operated between at least two players and is a five-card game with at least one deck of conventional 52 cards which includes four sets of cards. Each of the set of cards includes nine numerical value cards from 2 to 10, a Jack, a Queen, a King and an Ace. In this game, the Ace can be recognized or counted as either one or ten points, whereby the Jack, Queen and King are individually counted as ten points. To start, each player is dealt five cards each. After determining the points perceived on hand, each player must show three cards from his hand which add up to either ten, twenty, or thirty to continue playing the game. If a player cannot successfully do that, he is "disqualified" and must leave the game and wait for the next round. All players compare a comparison point value by summing up the point values of their remaining two playing cards with each other to determine the winner who has the highest comparison point value, wherein if the sum of the two playing card's total point value is larger than ten, the total point value is deducted by ten to achieve the comparison point value.

Patent CA-2257645-A1 (CA)
Inventor: HASSAN AMER A
IPC: G09C1/00
Filed: 1997-06-06
Abstract: Characteristics of a communication channel are used to establish key sequences for use in encrypting communicated information. In one embodiment, these characteristics are the impedances of the channel viewed from one transceiver to the other and vice versa. The keys can be established with computations equivalent to a bounded distance decoding procedure, and the decoder used to establish a key may be used for processing the subsequent data transmission.  Compared to classical and public-key cryptographic systems, an alternative mechanism for establishing and sharing key sequences that depends on a physical process is provided in which each party need not generate a pseudo-random quantity because the necessary randomness is provided by the properties of the communication channel itself. By using a channel decoder, the probability of two users establishing the same secret key is substantially unity, and the probability of an eavesdropper establishing the same key is substantially zero. Also, the number of possible keys is large enough that finding the correct one by exhaustive search is impractical.

Filed: 1997-10-30
Abstract: Il est possible de faire en sorte que la bande continue (26) d'un contenant (10) tubulaire à deux chambres conserve sa forme à travers ledit contenant, en façonnant sur ladite bande une ou plusieurs zones longitudinales modifiées (30) qui sont telles que la bande continue fléchit et se plie au niveau de ces zones de matière modifiée. La modification apportée à la matière de la bande consiste en un amincissement ou en une fragilisation de la bande continue visant à créer des points de fléchissement tels que des points de pliage. Il est possible de pratiquer l'amincissement ou la fragilisation de la bande mécaniquement ou chimiquement. Un procédé mécanique peut consister à utiliser un galet pinceur ou analogue pour amincir ou fragiliser une zone de la bande. Un procédé thermique consiste à appliquer de la chaleur à ladite zone. On obtient de cette manière une bande continue qui conserve sa forme et sa position dans la chambre tubulaire et qui n'entre pas en contact étroit avec la paroi latérale du contenant.
Patent CA-2272567-A1 (CA)
Inventor: BLOMGREN JAMES S
IPC: G06F7/544
Filed: 1997-11-20
Abstract: A multiplier array is modified to perform interpolations. The interpolations use a normalized first operand A between 0 and 1. The interpolation is the function B*A+C*(1-A). Standard multipliers accept two operands as inputs, but interpolations require 3 operands (A, B, C). The AND gates in Booth encoders (30) in a standard multiplier array are replaced by multiplexers. Each multiplexer selects a bit from one of the two operands (B or C) based on a bit of the first operand A. The interpolate operation multiplies the first operand A by the second operand B while simultaneously multiplying the bit-wise inverse of the first operand A' by the third operand C.

Filed: 1999-06-16
Abstract: A method and system for dynamically managing billing information for telecommunications service application use at the service application level rather than at the billing system level. Each service application, such as a call forwarding service application, is programmed with application level data records in which are stored the parameters of a given promotion, such as number of free uses, the start time and stop time of the promotion or rental period, etc. Each time a service application is subsequently used, the customer's use of the service application is logged in a customer data record. The customer's use is then compared to a corresponding application level data record. Based on this comparison, a billing record is provided to the billing system which instructs the billing system to either bill or not to bill the customer for the particular use of the service application.      No adjustment of the billing system is required for particular service application use because the billing system will receive a billing record with instructs, it to bill or not to bill. A record for each use of the service may be placed on the customer's bill, but only those uses for which the customer is to be charged will have a corresponding cost entry.
