Abstract: Measures for use in processing communication sessions in a telecommunications network are provided. Each communication session has a signaling path spanning a plurality of devices including one or more intermediate network devices and at least two endpoint devices, the signaling path comprising a plurality of signaling segments, each segment being between two devices in the plurality of devices. A first signaling message, comprising a first identifier associated with the communication session, is received via a first signaling segment for a communication session. At least part of the first identifier is transformed using a deterministic encryption algorithm to generate a second identifier. A second signaling message, comprising the second identifier, is transmitted via a second signaling segment for the communication session to associate the second identifier with the communication session.

Abstract: A system and method are provided for controlling a mobile device. The method includes, during use of the mobile device, interpreting at least one item, the at least one item corresponding to data or events detectable on the mobile device. At least action may then be determined, which are associated with the at least one item, each action capable of preemptively executing at least a portion of a task using features available on the mobile device. At least one of the actions may then be executed and a result associated with the execution of the at least one action provided.

Abstract: The present disclosure relates to a geographic information system (GIS) for collecting data for future usage. In operation, a spatial server receives an image request to a client device, applies a hash function to the image request to generate a standardized identifier. The GIS client device uses the standardized identifier, attributes of GIS data associated with the standardized identifier or the GIS data, or attributes of GIS data associated with a stored identifier that corresponds to the standardized identifier to determine whether to retrieve or cache a GIS data associated with the standardized or stored identifier for display on the client device.

Abstract: Measures for use in routing data in a data communications network. A request to route data to a given destination in the network is received. A route to the given destination is first selected from a plurality of routes to the given destination stored in a routing table. Routing the data to the given destination using the first selected route is attempted. In response to receipt of an indication that routing the data to the given destination via the first route failed, a second, different route to the given destination is second selected from the plurality of routes to the given destination stored in the routing table. The second selecting includes omitting, for the purposes of the second selection, at least one route to the given destination from the plurality of routes to the given destination stored in the routing table.

Abstract: A wireless communication system may include a plurality of nodes that use a medium access control (MAC) protocol to communicate over a shared medium or a primary channel. The MAC protocol may include a non-transmitting state during which one or more nodes are silent in the primary channel while two nodes in the wireless communication system are in communicating over the primary channel. Systems and methods described herein use medium access protocol (MAC) underlay signaling, which may include measuring or sensing availability for spectrum or transmitting data without the loss of network throughput over a secondary channel in a wireless communications system. In some embodiments, the systems and methods described herein use dynamic spectrum access (DSA) protocols to switch the channel of communication in the wireless communication system.

Abstract: A method and apparatus is provided which will provide over-pressure protection for an underground storage cavern by reducing the pressure of a pressurized gas stream originating from the an underground storage cavern to form a lower pressure gas stream, monitoring the pressure of a lower pressure gas stream and stopping the flow of the lower pressure gas stream to the pipeline should the pressure of the lower pressure gas stream exceed a threshold value.

Abstract: The patent involves the use of a portable device with a universal serial bus connector and memory which can store the unique biometrics of its registered owner for the purposes of identification; record the biometrics of any person attempting to use the device; confirm whether the user is the registered owner of the device; control access to electronic devices; monitor and record the operational activity of its user; store pre-defined value, duration and budgetary constraints; compare activity to pre-defined values, durations and budgetary constraints; store monetary value; visually indicate when operative; be electronically locked and de-activated; and connect and communicate directly or remotely to other electronic devices.

Abstract: An open chamber of predetermined size and shape is positioned within a pool bed so as to contain interconnected clusters of interconnected telescopic modules which occupy the chamber area. Each of the telescopic modules is independently extended and retracted in length vertically by the increase or decrease of the volume of water contained within a bellows, establishing in selected telescopic modules a specific reef size, shape, and orientation. When kinetic-energy is introduced upstream from a source, the kinetic-energy within the water passes over the reef, and generates a wave having specific features resulting from the properties of the specific reef configuration.
