Abstract: A gaming system comprising a gaming machine, a switching mechanism connected between a game controller and an audio visual output device, and an external controller in data communication with the game controller via a first communications link and connected via a second communications link to the switching mechanism. The gaming system is arranged such that, in a first mode, the game controller generates first game events based on the player input and outputs first audio visual data related to the first game events, and the gaming system controls the switching mechanism such that the first audio visual data is routed to the audio visual output device, and, in a second mode, the external controller generates second game events and outputs second audio visual data related to the second game events on the second communications link, and the gaming system controls the switching mechanism such that the second audio visual data is routed to the audio visual output device.

Abstract: An inventory control system and method that tracks inventories of items with RFID tags, includes a reader unit and an intelligent station that tracks RFID tags to determine item information of items to be inventoried. The reader unit transmits and receives RF signals. The intelligent station includes a first RF antenna connected to the reader unit by a first transmission cable through a first switch, and one or more additional RF antennae connected to the reader unit by the same first transmission cable through additional switches. An inventory control processing unit receives item information from the intelligent stations to update inventory information regarding the items to be inventoried.

Abstract: Techniques and apparatus are described for measurement of corrosion of drill pipe in a well bore during drilling. The techniques involve the use of a test coupon attached to the external surface of a drill string. In a preferred embodiment the test coupon comprises a metal plate mounted in an insulating material such as plastic. The test coupon is preferably secured within a recess in the external surface of a sub connected between segments of a drill string.
