Title: Method and apparatus for determining receiver orientation and/or vector infedelity in multi-component seismic data
Inventor: HORNE STEPHEN
IPC: G01V1/28
Filed: 2001-09-08
Abstract: Seismic data is processed to determine the slowness vector and components of the polarisation vector along first and second non co-linear directions. These are then used to obtain information about the orientation and/or vector infidelity of the seismic data receiver. In a second embodiment this information is obtained by calculating and comparing an expected polarisation vector to the observed polarisation vector. The system is designed for use with seismic acquisition equipment where the receivers are either autonomous or decoupled from their cable so that their positions cannot be defined by the position of the survey cable.

Patent GB-2373900-A (GB)
Title: Firmware mechanism for correcting soft errors
Inventor: QUACH NHON
IPC: G06F11/16
Filed: 2000-10-04
Abstract: A computer system includes processor having dual execution cores and a non-volatile memory that stores an error recovery routine. The processor's execution cores operate in lock step when the processor is in a redundant execution mode, and they operate independently when the processor is in a split execution mode. The error recovery routine is invoked when the processor detects a soft error while operating in the redundant execution mode. The error recovery routine switches the processor to split execution mode. In split mode, each execution core saves uncorrupted processor state data to a designated memory location and updates any corrupted data with corresponding processor state data from the other execution core. The error recovery routine returns the processor to redundant mode, initializes each execution core with the recovered processor state data, and returns control of the processor to the program thread that was executing when the soft error was detected.

Title: Mass spectrometer
Inventor: MALEK ROBERT
IPC: H01J49/42
Filed: 2003-03-10
Abstract: An improved FT-ICR Mass Spectrometer has an ion source 10 which generates ions that are transmitted through a series of multipoles 20 to an ion trap 30. Ions are ejected from the trap 30, through a series of lens and multipolar ion guide stages 40-90, and into a measurement cell 100 via an exit/gate lens 110. The measurement cell is mounted in a vacuum chamber 240 and this assembly is slideably moveable into a bore of a superconducting magnet 400 which provides the magnetic filed to cause cyclotron motion of the generated ions in the cell 100. By minimising the distance between the source 10 and cell 100, and by careful alignment of the ion optics, the ions can travel at high energies right up to the front of the measurement cell 100, where they are decelerated. The cell 100 extends in the longitudinal direction of the magnet bore and is coaxial with that. The ratio of the sectional area of the magnet bore to the sectional area of the cell volume is small (less than 3). The magnet is asymmetric and is relatively short on the ion injection side. The cell 100 is supported from in front of the cell and electrical contact is from the rear thereof.
