Title: Method and system for secure cashless gaming
Inventor: CHARRIN PHILIPPE A
IPC: G07F17/32
Filed: 2000-11-28
Abstract: A secure cashless gaming system comprises a plurality of gaming devices whic h may or may not be connected to a central host network. Each gaming device includes an intelligent data device reader which is uniquely associated with  a security module interposed between the intelligent data device reader and th e gaming device processor. A portable data device bearing credits is used to allow players to play the various gaming devices. When a portable data devic e is presented to the gaming device, it is authenticated before a gaming sessi on is allowed to begin. The intelligent data device reader in each gaming devic e monitors gaming transactions and stores the results for later readout in a secure format by a portable data extraction unit, or else for transfer to a central host network. Gaming transaction data may be aggregated by the portable data extraction unit from a number of different gaming devices, and  may be transferred to a central accounting and processing system for trackin g the number of remaining gaming credits for each portable data unit and/or player. Individual player habits can be monitored and tracked using the aggregated data. The intelligent data device reader may be programmed to automatically transfer gaming credits from a portable data device to the gaming device, and continually refresh the credits each time they drop below  a certain minimum level, thus alleviating the need for the player to manually enter an amount of gaming credits to transfer to the gaming device.

Patent CA-2411066-A1 (CA)
Inventor: LANZERSTORFER CHRISTOF
IPC: C02F11/131
Filed: 2001-05-21
Abstract: The invention relates to a method for treating a refuse material containing hydrocarbons, especially treating mill scale tails and/or grinding tails, whereby the refuse material, while preferably being moved, is heated by indirect heat supply and is liberated thereby from hydrocarbons, optionally together with other volatile constituents, especially H2O. To this end, a targeted decomposition of the hydrocarbons is carried out in the dryer at a low temperature. The decomposition is carried out by means of chemical and/or radiation-technology aids, which effect a decomposition of the hydrocarbons,  which are not easily volatilized, into easily volatile hydrocarbons, preferably a decomposition of hydrocarbons having a high molecular weight in to hydrocarbons having a lower molecular weight. The hydrocarbons, optionally together with the other volatile constituents, especially with the H2O, are at least partially removed from the vessel, in particular, by means of suction.  The invention also relates to a corresponding device for treating a refuse material containing hydrocarbons.
