Technical Examples
- A pool cue comprising a handle with standard taper section, a straight shaft section with tip at the end thereof, and a slidable sleeve disposed on the straight shaft section. An o-ring resides in a groove at the tip to prevent the slidable sleeve from falling off of the pool cue when the tip thereof is pointed downward. The tip o-ring can be detached to permit removal and/or replacement of the sleeve. A plurality of o-rings resides in grooves at the handle end of the straight shaft, approximately at the middle of the pool cue. The o-rings may be of the same diameter as the inner diameter of the sleeve, or alternately, slightly larger than the inner diameter of the sleeve, wherein the o-rings increase in diameter towards the handle. The sleeve can be positioned over the plurality of o-rings, wherein it is retained either by friction or interference.
- An improved resource pool is provided that provides for dynamic configuration and is comprised of code that is configured to be used for different subsystems, including JDBC, Connector, and JMS subsystems. Pool maintenance, resource object creation and timeout, multiple deque management, and pool state transition features are provided. An application server may include at least one resource pool object, wherein each resource pool object represents a resource pool in the application server. An improved prepared statement cache is also provided that works in conjunction with the resource pool implementation to more effectively provide for prepared statement processing.
- In a communications system having a first modem pool for communicating with a second modem pool, each modem pool including a plurality of modems and having at least one NEXT cancellation filter, a method for modem wake-up including the steps of, during a first time period, a) activating at least one of the modems in the first modem pool, b) deactivating at least one of the modems in the second modem pool, for at least one target modem in the first modem pool c) activating the first modem pool NEXT canceller filter, d) measuring the NEXT transfer function for the target modem and at least one other disturber modem in the first modem pool, and, during a second time period, e) activating at least one of the modems in the second modem pool, f) deactivating at least one of the modems in the first modem pool, for at least one target modem in the second modem pool g) activating the second modem pool NEXT canceller filter, and h) measuring the NEXT transfer function for the target modem and at least one other disturber modem in the second modem pool.
