Abstract: A method for distributing a packet to a plurality of moving nodes comprising receiving a packet containing at least a message, a sender identifier, a location of a sender, an identifier for a relay node and distance from the sender and the relay node, determining if a node receiving the packet is the relay node and immediately distributing the packet to a plurality of moving nodes if the receiving node is the relay node. If the receiving node is not the relay node, the method further comprises steps of waiting a set period of time, determining if a packet is received from a different sender containing the same message, within the period of time and distributing the packet to a plurality of moving nodes if a packet containing the same message is not received within the period of time. The distributed packet includes an identifier for a successive relay node.

Abstract: A device and method can detect, and also break, an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. To detect an occurrence of gas lock, an instantaneous value is monitored using a sensor. Then a controller compares the instantaneous value to a threshold value over a predetermined duration to thereby detect the occurrence of gas lock in the electrical submersible pump assembly. Sensors can include, for example, a differential pressure gauge, a pressure gage located in a pump stage located toward the inlet, a fluid temperature sensor located toward the discharge, a free gas detector located near the pump discharge, an electrical resistivity gage, a flow meter located within surface production tubing, and a vibration sensor attached to a tubing string to measure a vibration signature.

Granted: 2016-04-12
Abstract: The present invention pertains to improved communication quality of service in cellular communication networks and the like. A customer has the option to pay different fees for different tiers of service. Higher tiers may guarantee that a specific vocoder or bit rate is used; they may also include parameters such as maximum allowed dropped calls rate, maximum allowed jitter and maximum allowed latency.  Different tiers may be associated with customers' records.  The network may also afford high end cellular phones higher voice quality by comparing a phone to a look-up table indicating the level of service associated with the phone.  A calling mobile station or a receiving mobile station may ask the other mobile station to change to a more robust vocoder or bit rate to ensure a higher quality phone call.  Furthermore, the user may also opt to change the quality level before or during a call.
