  • Patent number: 7738376
    Abstract: A flow control method and system including an algorithm for deciding to transmit an arriving packet into a processing queue or to discard it, or, in the case of instructions or packets that must not be discarded, a similar method and system for deciding at a service event to transmit an instruction or packet into a processing queue or to skip the service event. The transmit probability is increased or decreased in consideration of minimum and maximum limits for each flow, aggregate limits for sets of flows, relative priority among flows, queue occupancy, and rate of change of queue occupancy. The effects include protection of flows below their minimum rates, correction of flows above their maximum rates, and, for flows between minimum and maximum rates, reduction of constituent flows of an aggregate that is above its aggregate maximum. Practice of the invention results in low queue occupancy during steady congestion.

  • Publication number: 20070060387
    Abstract: A method includes periodically over a given day comparing an actual status for a casino player station with a current target status for the casino player station. The actual status for the casino player station specifies an actual game presentation operating at the casino player station at the particular time. A modification command is issued to the casino player station in the event that the current target status for the casino player station does not match the actual status for the casino player station. In response to the modification command, a target game presentation is launched at the casino player station. This target game presentation is specified by the current target status for the casino player station and is different from the actual game presentation specified by the actual status for the casino player station. The method thus facilitates configuration changes in the various player stations in a gaming system to ensure the desired game presentations are available to players.

  • Patent number: 4509449
    Abstract: An elongated container, open at end, is nearly filled with frozen fluid. Urethane foam insulation around the container admits access only to the open end of the container with the frozen fluid level below the insulation. An elongated heat conducting indicator member fits loosely within the container so that fluid may pass therebetween. An elastic band over the end of the indicator/conductor and around the base of the insulation maintains an end of the indicator/conductor in contact with the frozen fluid. The indicator/conductor is calibrated in degree-hours or other temperature-time units. The indicator/conductor may be a hollow flat-bottomed tube with air inside acting as the heat conductor from the exterior air to the contact end of the block of frozen fluid.

  • Patent number: 4327928
    Abstract: A fork structure for a motorcycle in which the steering column is connected to the wheel axle so that while it is free to move longitudinally on shock mounts, it is constrained against any significant rotatable motion relative to the axle, thereby minimizing bushing wear and providing tighter response in the steering control. The front end forks of a motorcycle are formed by a pair of tubular members which are rigidly attached to the steering column. These tubular members have slots formed near their bottom ends, these slotted portions being fitted over the opposite ends of the cycle axle. Shock mounts are mounted within the tubular members. The shock mounts include a lower cylindrical bushing which is fixedly attached to the axle and a shock absorber mounted above the bushing with one end of the shock absorber being attached to an extension which is attached to the top end of the tubing.
