Abstract: A prepaid messaging solution using open networking standards (e.g., TCP/IP) to support pre-payment of Internet messaging services. The disclosed prepaid architectures/methods determine if a subscriber has sufficient account balance to deliver a short message, prior to message delivery. A message may be prevented from being delivered (at the source end or destination end) if a subscriber account has insufficient funds. A prepaid tariff engine supports remote interaction with the SMSC and web chat servers to apply real-time billing for each message. A service provider may define subscriber rates and/or tariffing plans to apply real-time billing for sending/receiving messages. Message billing may be based upon, e.g., rate per message, message count, character count, Time of Day, Day of Week, message type, and/or mobile location.

Abstract: A method using airport surveillance data to output a location of a delay and an amount of time a vehicle is subjected to the delay during a movement of the vehicle between two locations, the delays being observed in the surveillance data as a knot of several data points. A first method is used to identify proposed knots based on distances between individual data points within the data. A second method is used to identify proposed knots based on the speed of the vehicle. Another method can be used to separate proposed knots have been incorrectly joined together. This method performs the separation by arranging the data points into a two-dimensional grid to form clusters of grid cells having data points. The location of the individual cells is then analyzed to determine whether clusters should be separated. Each of the remaining clusters defines a hold where the vehicle is delayed.

The sensor device coalesces the one or more received alarm messages from the one or more upstream sensor devices with the alarm message generated at the sensor device, to form a coalesced alarm message, and transmits the coalesced alarm message downstream towards the downstream destination device, after expiration of the delay.

The computer transmits consumption information to a central location for billing, inventory management, market research information and can transmit the same to other processing units such as hand held computers possessed by staff that replenishes the facility. This system prevents used items from being placed back into the housing facility and being incorrectly accounted for as usable/billable and provides for greater room servicing efficiencies.

Abstract: In one embodiment, one or more routing trees may be determined based on corresponding root nodes to reach a particular receiving node in a computer network. A delay value may be calculated at each node of the routing tree, the delay value inversely proportional to a distance between each respective node and the root node of the tree. Upon detecting a trigger at a particular node of the tree to transmit a stormed message to the particular receiving node (e.g., an alarm), the particular node may initiate a timer to count down the delay value in order to receive any upstream node stormed messages prior to expiration of the timer. The particular node may then coalesce the upstream node stormed messages with the stormed message of the particular node, and may transmit the coalesced stormed message downstream along the tree toward the particular receiving node upon expiration of the timer.

Abstract: Delay associated with each of two signals along respective transmission paths is accurately measured using a delay measurement circuit that is fabricated in situ on the actual device where the circuitry for propagating the two signals is fabricated. Thus, the measured delay associated with each of the two signals is subject to the same fabrication-dependent attributes that affect the actual circuitry through which the two signals will be propagated during operation of the device. The skew between the two signals is quantified as the difference in the measured delays. Coarse and fine delay modules are defined within the transmission path of each of the two signals. Based on the measured skew between the two signals, the coarse and fine delay modules are appropriately set to compensate for the skew. The appropriately settings for the coarse and fine delay modules can be stored in non-volatile memory elements.
