Patent number: 7328838Abstract: Methods and systems for detecting counterfeit cashless instruments are disclosed. A pattern of attempted redemptions or other transactional recordings of gaming machine printed tickets, vouchers or other cashless instruments having identification numbers with valid predictable fields but invalid unpredictable fields can indicate a likely counterfeiting attempt or operation. Occurrences can include a thief or other unscrupulous party discovering which gaming machine printed ticket fields lend themselves to prediction and which do not, and then attempting to guess at some of the randomly generated numbers in hopes of coming up with a valid number or number set. In addition, stored hash numbers can be compared to a hash number generated according to a one-way hash function. A pattern of invalid hash numbers can also indicate a likely counterfeit attempt.Type: GrantFiled: September 9, 2004Date of Patent: February 12, 2008Assignee: IGTInventors: William R.

Patent number: 7327682Abstract: Method and devices are provided for allocating network resources in a flexible manner. In some implementations, a customer's unused resources for a particular type of service are assigned to another type of service. In other implementations, a first customer's unused resources are assigned to a second customer, e.g., in exchange for a relatively lower service charge to the first customer. The unused bandwidth may be assigned on a hierarchical or a non-hierarchical basis. In preferred embodiments, resources are allocated using a token bucket methodology. Preferably, high-priority resources are not compromised by the allocation scheme. The discipline or manner in which resources or bandwidth are shared may be specified in a static fashion or information regarding the state of congestion in the network maybe used to generate a dynamic (time varying) specification.Type: GrantFiled: June 27, 2003Date of Patent: February 5, 2008Assignee: Cisco Technology, Inc.Inventors: Prashant Gandhi, Robert Klessig, Cedric Druce
