Patent CA-2212925-C (CA)
Inventor: VAN STEENWYK DONALD H
IPC: G01V3/26

Granted: 2002-03-26
Abstract: A method to determine the earth's magnetic field vector along a sub-surface wellpath having unknown and possibly changing azimuth, in the presence of a magnetic disturbance caused by a magnetic source external to the wellpath includes estimating the three components of the earth field along the three axes of a magnetic sensor package by a polynomial function of measured depth along the wellpath. Magnetic survey accuracy is thereby improved. Upon removal of the earth's magnetic field from the measurements, the resultant magnetic field of the disturbance is determined and can be used to determine the position and orientation of the source of the disturbance.

Granted: 2006-07-11
Abstract: A system and method for performing call signalling for multimedia call setups. A user equipped with calling terminals of various types may initiate a call from any of these terminals, and the call is intercepted and handled by the system. A calling agent looks up an E-mail address for the called party, and sends a setup request E-mail to a called agent associated with the called party. The called agent determines the current terminal that the callee is using, and together with the calling agent a call medium and other parameters are established. Then a connection is made between a calling terminal and the current terminal. This provides a generic signalling system for a callee using a wireline terminal, wireless terminal, or H.323 terminal to be connected to a called terminal also being any one of these or other types.

The pairs of exciters and sensors are arranged on a substrate in various formations. A/D converters are provided to respective detection signals. A frequency of the oscillation signal supplied to the exciter is controlled by various oscillation signal generation circuits. Bandpass filtering for extracting the exciter waveform, low-pass-filtering for extracting a natural blood pressure waveform, phase difference detection processes are provided by a microprocessor, wherein the bandpass filtering and low-pass-filtering processes may be replaced with a bandpass filter and a low pass filter, and their outputs are selected by a switching circuit and supplied to the microprocessor through one a/d converter. The frequency of the oscillation signal is controlled to an optimum frequency by detecting the detection signal and estimating the attenuation, dispersion, phase shift with respect to different frequency and by determining one of the different frequency in accordance with the estimation result. The waveform of the oscillation signal is controlled to an optimum waveform similarly.
