IPC: H04M11/00
Filed: 2000-09-05
Abstract: A mobile station scans for electromagnetic signals representing control channels of the public wireless system and the private wireless system. The mobile station measures a received signal parameter of at least one of the scanned control channels. The hybrid communications network may transfer the mobile station's service from the public wireless system to the private wireless system, if the measured signal parameter meets or exceeds a private target. Alternately, the hybrid communications system may transfer service from the private wireless system to the public wireless system, if the measured signal parameter meets or exceeds a public target.  A service control point maintains a central database of user profiles updated in response to the transferring procedure. A service node redirects a data message for the mobile station through the public wireless system or through the private wireless system, as facilitated by the central database, to deliver the data message to the mobile station during its operation on an active one of the wireless systems.

Title: Balancing system with a force multiplying device
Inventor: BAULIER DOMINIQUE R M
IPC: B66D3/18
Filed: 2001-01-17
Abstract: A force multiplying device is provided for use in conjunction with a balancing system for moving a load from an elevated position and to a predetermined lower position. The balancing system includes an extendable cable with a free end adapted to be secured to and exert an upward force on the load. The device includes a base which is secured to the load and a first lever pivotally secured at an intermediate point to the base about a generally horizontal axis. A fixed length flexible member has one end secured to a first end of the lever and a second end fixedly secured to a support position above the load. The length of the flexible member is such that the flexible member is in a fully extended position when the load is in the predetermined lower position. An elongated rocker arm has a first end in abutment with the base while the cable from the balancing system is secured to a second end of the rocker arm. A second end of the lever is pivotally secured to an intermediate point of the rocker arm so that, as the load nears the predetermined lower position, the first end of the lever pivots upwardly and simultaneously pivots the second end of the rocker end downwardly to thereby exert an increased downward stroke on the cable, and a corresponding upward force on the load.     By construction, the length of each rocker and lever arms is such that the distance between the flexible member and the extendable cable is minimal.     Furthermore, two systems like that can be symmetrically combined in such a way that the center of gravity of the load to be balanced remains in the same plane that the pair of flexible members and extendable cables, avoiding by that any swinging of the load during its entire stroke.

Title: Control system for deep set subsurface valves
Inventor: BEALL CLIFFORD H
IPC: E21B34/10
Filed: 2001-05-17
Abstract: The hydraulic control system for operating a flow tube in a subsurface safety valve is disclosed. An isolation piston is used in conjunction with an operating control line and an engagement control line. Both control lines run from the surface. The isolation piston is spring loaded to equalize pressure across a dynamic piston to allow the flow tube to be shifted by a power spring to allow in turn the subsurface safety valve to close.  Application of pressure on the engagement control line directs pressure applied through the operating control line to the top of the dynamic piston thus shifting the flow tube downwardly to open the subsurface safety valve. In an alternative embodiment, a coaxial control line directs fluid to the top of the dynamic piston and additionally to a parallel path leading to the bottom of the dynamic piston where a control valve is mounted. The control valve can be actuated hydraulically, electronically or other ways such that when it is closed the pressure applied to the dynamic piston shifts the flow to open the subsurface safety valve. A loss of signal to the control valve equalizes the dynamic piston allowing the flow tube to shift.
