摘要： An improved digital fluxgate magnetometer that uses digital logic and a high resolution digital to analog converter to digitize a magnetic signal for use by signal processing algorithms. The magnetometer includes an oscillator that outputs an oscillator signal and a magnetic fluxgate sensor having a drive coil coupled to the oscillator, a feedback coil, and a sense coil. An analog multiplier is coupled to the sense coil and the oscillator and outputs a signal to an analog low pass filter. A comparator is coupled to the analog multiplier, and a register is coupled to the comparator and outputs a logical 1 or a logical 0 in accordance with the output of the comparator. A digital filter receives the output of the register and produces a digital output of the digital fluxgate magnetometer. A high resolution digital to analog converter is coupled between the register and the feedback coil of the magnetic fluxgate sensor in a feedback loop of the sensor. The digital to analog converter produces a very high resolution digitized output (typically >22 bits) that is necessary to adequately represent the dynamic range of the sensor.

摘要： Methods including a Kalman filter tracking method for localizing a magnetic field source and which employs a linear perturbation method.

摘要： A target's magnetic dipole includes both a permanent component and an induced component that is caused by the interaction of the target at a given heading with the ambient magnetic field. In order to accurately classify targets, a library of characterization matrices is built for a plurality of candidate targets. The matrices characterize what the magnetic dipoles would be in a given ambient magnetic field at a particular heading. In practice, some localization algorithm is used to provide a target's magnetic dipole and heading. Magnetic dipoles for each of the candidate targets are predicted using the target's heading, the ambient magnetic field, and the characterization matrices. The target is then classified as the candidate target(s) providing the best match to the target's measured magnetic dipole.

摘要： A method of gate reduction in a gate width limited logic array. Common sub-groups of inputs associated with an array output are collected. Logical functions are then reimplemented, using the common subgroups implemented as single gates resulting in an implementation of the logical functions that uses few active devices. The method uses a constraint typically placed on gate array logic that gates wider than four inputs cannot be used. The method is applicable to combinatorial digital logic devices only. The method of the present invention is applicable to large scale integration (LSI) and very large scale integration (VLSI) integrated circuit devices.
