Title: Three axis magnetometer sensor field alignment and registration
Inventor: LO ALLEN K
IPC: G01V3/08
Filed: 1992-02-17
Abstract: An alignment process is applied to each sensor (12a-12n) of an array (12) of three axis magnetic sensors to electronically align the three axes of each sensor (12a-12n) after the array (12) has been deployed. The alignment process compensates for each sensor (12a-12n) not being aligned perfectly with the earth's N-S, E-W and vertical magnetic field components. A field registration process is applied to each sensor (12a-12n) of the array that uses a dipole moment detection and localization process and the alignment process combined with a known calibrated dipole source (13) to define the shape of the array (12). The present invention improves the performance of the array of sensors (12a-12n) in detecting magnetic anomalies by digitally compensating for sensor-to-sensor nonalignment and magnetic interferers within interfering range. The alignment process electronically aligns the three axes of each of the sensors (12a-12n) to gain maximum performance from the sensor array (12). Using digital signal processing techniques reduces the physical deployment requirements on the sensors (12a-12n)and their relative positions. The alignment process allows the use of three axisvector magnetometers in a distributed field with out having to lay each sensor (12a-12n) in perfect alignment with the earth's three magnetic axis. This simplifies the deployment requirements and allows for maximizing the system performance.

Abstract: An  automatic blood  pressure  gauge  uses  two pulse width modulated  solenoid  valve  to  achieve  a  substantially  linear deflation curve.  The solenoid valves are controlled by a valve switching signal that has a fixed fundamental frequency.  The gauge samples and digitizes the cuff pressure signal. To eliminate artifacts related to the valve switching signal, a microprocessor in the gauge filters the sampled data pressure signal using a third-order Chebychev 2 filter having a zero at the frequency of the valve switching signal.   A single timing source used for controlling the microprocessor is also used for developing both the valve switching signal and the sampled data pressure signal, in order to achieve high attenuation of the valve switching signal components in the pressure signal via the Chebychev filter.   In addition,  the analog to digital converter which develops the digital samples is a sigma-delta type converter which has a Nyquist frequency greater than the frequency of the valve switching signal and which includes a low pass filter that further attenuates the switching signal artifacts relative to the patient's blood pressure pulse signal.  Additionally, one of the solenoid valves is used when relatively low flow rates are desired from a relatively highly pressurized cuff while the other valve is used when relatively high flow rates are desired from a cuff having a relatively low fluid pressure.
