Title: Gaming device providing tournament entries
Inventor: BAERLOCHER ANTHONY J
IPC: A63F13/00
Filed: 2002-09-12
Granted: 2007-07-24
Abstract: The present invention provides a gaming device which enables a player to enter a tournament based on a qualifying outcome achieved on the gaming device. In one embodiment, the gaming device includes a set of reels including at least one qualification symbol. If at least one qualification symbol is displayed within a display device of the gaming device, the player qualifies for a tournament to be played at a later time. The tournament is preferably a slot machine tournament. One or more prizes are awarded at the tournament, including high value items such as cars and motorcycles as well as lower valued items such as hats, T-shirts, jackets, memorabilia and other merchandise. In this regard, the tournament provides convenience to a casino as far as prize acquisition, distribution and record keeping are concerned because prizes are awarded at one specific event instead of on sporadic occasions. The payout percentages of the gaming devices providing entry into the tournament are set relative to a cost of the tournament.

Abstract: Endothelial dysfunction is a known indicator of cornary artery disease. Endothelial dysfunction is detected by measuring tracer presence in arteries following the release of blood flow into the limb after a period of blockage of blood flow into the limb. The blood flow is measured in a pair of laterally opposed limbs, such as the patient's forearms, and the tracer presence is compared between both limbs. An efficient tracer is a radionuclide and the non-invasive measurement of the radionuclide is carried out by gamma ray detection.

Abstract: The improved sprayer system of the present invention utilizes a docking drogue and probe assembly to quickly and easily allow refilling of the sprayer tanks with a material from an enlarged nurse tank. The coupling of the drogue and probe allows for fluid communication, as well as electronic transmission of material data to a processor in the prime mover. This processor software also receives input regarding field data and crop data, as well as feedback data from the sprayer regarding the material application. A GPS system on the prime mover allows for tracking the spraying operation, while a time stamp in the processor software tracks the timing of the spraying operation. This system thus allows for accurate accountability and traceability for the use of materials during the spraying operation.

Granted: 2012-08-28
Abstract: A system for storing information having a predetermined use which requires the information to be secured. The information may comprise credit card details used to complete a transaction. The system includes: (a) A client system for storing an encoded version of the information and an identifier. The encoded version is generated from first data of the information and an encoded version of the second data of the information. The information can be generated from the first data and the second data, and the predetermined use is infeasible with only one of the first data and the second data. (b) A remote server for storing the second data and an encoded identifier generated from the identifier. The client system sends at least the encoded version of the second data to the remote server. The client system or the remote server is able to generate the information from the first data and the second data. Accordingly, only part of the information to be secured is stored locally on the client system, whilst the other part is stored on the remote server, and neither the client system nor the remote server have a record of the entire information.
