Abstract: A personal communications internetwork provides a personal communications internetwork providing a network subscriber with the ability to remotely control the receipt and delivery of wireless and wireline electronic text messages. The network operates as an interface between wireless and wireline networks. The subscriber's message receipt and delivery options are maintained in a database which the subscriber may access by wireless or wireline communications to update the options programmed in the database.

Abstract: A petroleum well has an electronic module and a number of sensors which communicate with the surface using the tubing string and casing as conductors. Induction chokes at the surface and downhole electrically impede AC flow through the (tubing or casing if so configured) with the resulting voltage potential useful for power and communication. A high bandwidth, adaptable spread spectrum communications system is used to communicate between the downhole electronics module and a surface master spread spectrum modem. Downhole sensors, such as pressure, temperature, acoustic and seismic sensors accurately assess downhole physical conditions. In a preferred form, the electronics module and sensors are wireline insertable and retrievable into a side pocket mandrel in the tubing string. Permanent downhole sensors that can communicate with the surface allow such diverse applications as optimizing well and field performances, monitoring and assessing the geophysics of the fomrations around the well, assessing well and reservoir reserves, assessing reservoir conditions.

Abstract: A method for detecting and transporting dynamic presence information over a wireless and wireline communications network comprises determining client device capabilities relating to user presence information that may be obtained from the client device and determining a presence configuration of the client device. The presence configuration defines information to be provided to a presence agent. The presence configuration also defines one or more action to be performed upon notification of an event occurrence. The method also includes collecting dynamic presence information based at least in part on the client device capabilities and the presence configuration.
