Granted: 1995-10-10
Abstract: A method and apparatus for measuring fluid flow rates, and the absolute open flow (AOF) potential of a subterranean formation penetrated by a wellbore. The present invention can be described as a formation fluid flow rate test tool which is conveyed and operated on a wireline logging cable. The down hole test tool comprises an arrangement of inflatable packers to isolate an interval and a pump which extracts fluid from the formation through an inlet below the upper most packer. The method allows for sequentially increasing or decreasing the pump rate and hence flow rates and measuring the corresponding pressures. From this data, the reservoir flow characteristics, properties and deliverability can be accurately calculated, which was not previously permitted with other known wireline conveyed sampling and testing tools. Additionally, the present invention allows for the reservoir parameters to be obtained under dynamic conditions, emulating an AOF test which was previously only obtained after completion of the well. This method and apparatus presents an economical and time effective technique with which to enter into a decision regarding the disposition of a wellbore.

Granted: 1996-07-02
Abstract: A mobile telephony system includes an internal sub-system, which is installed in a building and an external part-system. The internal sub-system has internal base stations which are connected to a mobile switching centre, to which external base stations are also connected.  The mobile telephony system is assigned a frequency band which comprises a plurality of channels.  The external part-system is divided into cells and has fixed channel assignment with a few channels to each external base stations.  The internal sub-system is adaptive and the internal base stations have access to all channels of the system.  In order to determine whether a mobile station belongs to the internal or to the external part-system, an internal identification word is transmitted from the internal base stations and an external identification word is transmitted from the external base stations.  When the signal strength of the internal identification word exceeds a threshold value, the mobile station transmits an internal identification word to the internal base stations.  If the signal strength falls beneath this threshold value, the mobile station identifies itself to the external part-system.

Filed: 1990-09-10
Granted: 1995-07-11
Abstract: A method and apparatus to enable a  low power telephone controller (50) to operate with either a carbon microphone (51) or a dynamic microphone (51)  is described.   A jumper (JP1)   in a preamplifier and filter circuit (33) is preset to accommodate the audio  transfer  characteristics  of  one  or the  other  type  of microphones.  For either microphone, a small DC current of less than 500uA is used to sense the presence of either type microphone and serves the dual role of biasing the carbon microphone (51) to the appropriate level to be amplified so that the input to an audio circuit in the controller (50) is very nearly the same for either microphone.   The audio circuit then processes and dynamically balances the signal to the telephone line, where it is output.

Title: Cellular radio telephone communication system for multi-mode mobile radio telephone stations
Inventor: DAHLIN JAN ERIK AKE STEINER
IPC: H04W48/20
Filed: 1992-08-28
Granted: 2003-08-05
Abstract: The present invention is directed to a cellular mobile radio telephone system in which mobile stations may select either analog or digital control channels.      Analog and dual-mode mobile stations are equipped to become multi-mode mobile stations which monitor both analog and digital control channels depending on the selected mode. Downlink multi-mode mobile stations, while required to use analog control channels for call access, may nonetheless scan digital control and paging channels to receive downlink control and paging communications from the land-based system. Bi-directional multi-mode mobile stations have the same capabilities as downlink mobiles but also are equipped to transmit control information to the land station over the uplink digital control channel. If no digital control channel is available, the multi-mode mobile stations scan primary and secondary sets of analog control channels.      In this way, analog and dual-mode mobile stations may benefit from the advantages of monitoring digital control channels and digital paging channels including multiple pages per channel and battery-saving capabilities.

Title: Disk clamping device for magnetic disk drive
Inventor: IWABUCHI MASANORI
IPC: G11B17/02
Filed: 1993-11-16
Granted: 1999-10-05
Abstract: A disk clamping device in a magnetic disk drive includes a clamper which presses an uppermost one of a plurality of magnetic recording disks and a clamping force transmission member which presses the clamper against the uppermost magnetic recording disk. A material having a small Young's modulus, such as a high polymer material and a super elastic material, is used for the clamper or the clamping force transmission member, or both of them. The device may include a shim whose Young's modulus is larger than that of the clamper which presses the uppermost disk through the shim. The arrangement makes it possible to reduce the variations in the clamping force caused by a lack of manufacturing precision or a change in temperatures and to provide a stable clamping force. The uniform clamping force enables to reduce the occurrence of undulation in the disks otherwise caused by the circumferential clamping force differences in the clamper.
