摘要： Disclosed herein are a method for providing a parameter for coil design and an apparatus for the same. The method includes receiving a magnetic field parameter value for an arbitrary coil from a user; determining whether there is a constraint on each of an electrical parameter group and a geometric parameter group; when it is determined that there is a constraint on any one of the two groups, setting a parameter range for a second parameter group on which there is no constraint based on a fixed parameter set of a first parameter group on which there is a constraint; and selecting a final parameter set of the second parameter group for satisfying the magnetic field parameter value within the parameter range and outputting parameter values of the fixed parameter set and the final parameter set to the user.

摘要： Magnetic sensor system including an assembly comprising first, second, and third scalar point-sensor magnetometers being fixedly mounted with respect to one another such that the position of each magnetometer's axis is invariable with respect to the other magnetometers' axes. When the sensor assembly is in operation, each magnetometer's axis forms an angle with ambient magnetic field lines. Each magnetometer has an operating range defined with respect to a range of values of the angle formed by its axis and the ambient magnetic field. The magnetometers are positioned such that at least one of magnetometers is within its operating range at any point in time. Each magnetometer has an output signal. Computer processor determines which of the output signals is to be used any particular point in time in the sensing of local variations in the ambient magnetic field. Method of operation of the magnetic sensor system/assembly is disclosed.

摘要： A system includes a helically polarized magnet having a plurality of north and south poles circumferentially and helically patterned along a linear axis. Magnetic flux varies at different positions along a linear path in a direction aligned with the linear axis. A multi-axis magnetometer and/or magnetometer array is configured with at least two sensing coils to detect the position of the helically polarized magnet by sensing the magnetic flux variations at the different positions along the linear path.

摘要： Systems and methods may provide for obtaining first sensor data associated with a gyroscope and obtaining second sensor data associated with a magnetometer. Additionally, the first sensor data, the second sensor data and an extended Kalman filter may be used to calibrate the magnetometer. In one example, a sampling rate of the magnetometer is increased before obtaining the second sensor data and the sampling rate of the magnetometer is decreased after calibration of the magnetometer.

摘要： A system and method for locating an object within a structure includes a magnetically-responsive member coupled to the object. A magnetic field generator generates a magnetic field in the presence of the structure. The generated magnetic field causes the magnetically-responsive member to output a signal when the magnetically-responsive member is in the presence of the magnetic field. A detector may include a sensor coupled to a control unit. The sensor detects the signal output by the magnetically-responsive member. The control unit locates the object based on detection of a third harmonic of the signal.

摘要： A two-axes MEMS magnetometer includes, in one plane, a freestanding rectangular frame having inner walls and four torsion springs, wherein opposing inner walls of the frame are contacted by one end of only two torsion springs, each torsion spring being anchored by its other end, towards the center of the frame, to a substrate. In operation, the magnetometer measures the magnetic field in two orthogonal sensing modes using differential capacitance measurements.
