  • Patent number: 6922562
    Abstract: A method for providing information services to a wireless device roaming in a wireless system is disclosed. Normal network message traffic information is obtained from a wireless system. The normal network message traffic information is transmitted to a protocol converter. In the protocol converter, roamer information is extracted from the normal network message traffic information and converted into a protocol analyzer format. A query is transmitted to a Mobile Switching Center requesting information regarding the wireless device's serving cell or location. Information regarding the wireless device's serving cell or location is received and combined with the converted roamer information to form a roamer trigger. The roamer trigger is transmitted to protocol analyzer. In the protocol analyzer, specific information pieces regarding the wireless device are extracted. The extracted specific information pieces are transmitted to a data interpreter for translation and delivery to a wireless device.

  • Patent number: 5265675
    Abstract: A well conduit cutting and milling apparatus conveyable into and out of a well on coilable tubing using a tubing injection unit. The apparatus includes tubing or casing cutting arms which are radially extendable and retractable with respect to a cylindrical support body by pressure fluid operated pistons. The apparatus is made up of multiple end-to-end connected units including one which supports interchangeable cutting and milling arms and units which have radially extensible and retractable stabilizing arms which engage the inner wall of the tubing or casing to centralize and stabilize the apparatus during operation. The cutter and milling arms are modified for milling away a section of tubing by moving the apparatus in an upward or out of the well direction. The cutting elements are preferably cylindrical hard metal members which are supported on the arms for cutting away an end face of the tubing in a tangential direction of movement.
