A wagering game system and operations for a wagering game system include a plugin architecture and framework in which wagering game system applications utilize plugins to provide functionality for an application or service. The plugins may be independently tested and verified by a jurisdictional testing agent to confirm that the operation of the plugin complies with the rules and regulations for a jurisdiction. If plugins are added or updated, a system vendor may submit only those plugins that require jurisdictional approval to a testing agent. An application or service may download plugins that are approved for use in the jurisdiction in which the application or service is operating.
摘要:
There is disclosed a system for identifying a source location of an electromagnetic signal having a known waveform. Radio receiving equipment located at three of more monitoring stations receives and demodulates a radio frequency signal from a common source. A time stamp generator applies a time stamp to each block of N digital data samples derived from the received radio frequency signal at each monitoring station. A GPS timing signal can be used to synchronize the time stamp generator in each monitoring station. Further, replica generating hardware and/or software at each monitoring station periodically synchronously generates a replica waveform. An autocorrelation processor at each monitoring station determines a time offset between an occurrence of the known waveform in the signal, and an occurrence of the replica waveform at each monitoring station. The system also includes communication devices at each monitoring station for communicating the time offset from each monitoring station to a central processor which calculates a position of the source location using the time offset communicated from each monitoring station.

There is discloses a new method for identifying an electromagnetic signal having a known waveform. The method includes using a lightning matched filter receiver having a bank of filters matched to nominal but arbitrary lightning waveforms for detecting lightning. The use of a lightning matched filter receiver facilitates detection of lightning discharges below the noise level. Positioning three or more monitoring stations at different spaced apart geographic locations where each monitoring station has a lightning matched filter receiver where the filters are matched to nominal but arbitrary lightning waveforms can be used to detect and determine the location of a lightning discharge.

A dispenser for rolls of sheet material includes a base or housing for supporting one or more rolls of sheet material. An extension from one side of the housing includes a receiver for receiving one end of an axle/push rod. A journal is positioned on the opposite side of the housing from the receiver. The journal and receiver in turn are positioned along an axis. The axle/push rod has a first section which can be inserted into the center passageway through the roll and extend at least slightly out of the opposite side of the roll. A second section of the axle/push rod abutting the side of the roll has a diameter greater than the passageway through the roll and allows the axle/push rod to push the roll rotatably supported on the first section out of the housing. The entire length of the axle/push rod is greater than twice the length of a roll. The roll on the axle/push rod is then exposed outside the housing for dispension of sheet material. Once the roll exposed for dispension is expired, the axle is withdrawn from the receiver and withdrawn through the housing, with a half turn the remaining rolls drop in the housing and the axle right side up is reinserted into the next succeeding roll passageway. The axle/push rod is used to then push the next roll out to where it is positioned for dispension.

An improvement to the process of applying a rocket motor liner to an inside surface of a rocket motor casing by coating the casing with a rocket motor liner composition and then curing the liner composition. Typical rocket motor liner compositions include the product of a hydroxyl-terminated polybutadiene prepolymer; a diisocyanate curing agent for forming urethane linkages with said prepolymer; a trifunctional aziridine bond promoter; a filler; and a curing catalyst comprising maleic anhydride, magnesium oxide, and triphenyl bismuth. This invention may use an alkaline carbon black filler and/or a curing catalyst which does not include magnesium oxide.
