摘要： A CubeSat magnetometer array system having a housing having CubeSat dimensions, a host computer, and a magnetometer array system. The magnetometer array system includes a circuit board mounted within the housing, a plurality of magnetometers operably mounted on the circuit board, and a microcontroller system operably coupled with the plurality of magnetometers. The microcontroller system is configured to synchronize data from the plurality of magnetometers, utilize machine learning processes to identify and reduce noise in the synchronized data, and output a signal representative of a magnetic field with reduced noise due to the machine learning processes. A communication interface is operably coupled with the host computer and the microcontroller system and configured to communicate the signal to the host computer.

摘要： Magnetic field components are measured at multiple longitudinal positions and used to calculate estimated longitudinal position and length of a transversely localized electric current segment flowing across a gap between conductive bodies. The apparatus can be used with a remelting furnace. The electrode and ingot act as the conductive bodies, and arcs, discharges, or slag currents are the current segments spanning the gap. Actuators for movable sensors can be coupled to the sensors in a servomechanism arrangement to move the sensors along with the moving gap. An actuator for moving one of the conductive bodies can be coupled to sensors in a servomechanism arrangement to maintain the gap distance within a selected range as the gap moves.

摘要： A method of determining an orientation α,β of a magnet which is pivotable about a reference position having a predefined position relative to a semiconductor substrate, comprising: a) determining at least two of the following magnetic field gradients: i) a first magnetic field gradient dBx/dx; ii) a second magnetic field gradient dBy/dy; iii) a third magnetic field gradient dBz/dx; iv) a fourth magnetic field gradient dBz/dy; b) determining a first angle α based on at least one of the magnetic field gradients; c) determining a second angle β based on at least one of the magnetic field gradients. A sensor device is configured for performing this method. A sensor system includes such sensor device and a magnet, optionally connected to a joystick.

摘要： Position sensors, including linear position sensors, that utilize magnetic field(s) are disclosed. Disclosed sensors include flux emitters and sensor assemblies. The sensor assemblies include flux collectors that interact with magnetic fields from flux emitters and with a magnetism sensing device. Flux emitters have arrangements of magnets that when combined with the sensor assembly can provide a constantly increasing or a constantly decreasing signal across a range of relative movement.

摘要： In one embodiment, an apparatus includes a first magnetometer that measures a magnetic induction and direction of a magnetic field. The first magnetometer has a first coordinate frame that includes a first x axis, a first y axis, and a first z axis. The apparatus includes a second magnetometer that measures the magnetic induction and direction of the magnetic field. The second magnetometer has a second coordinate frame that includes a second x axis, a second y axis, and a second z axis. Each of one or more of the second x axis, the second y axis, or the second z axis is has a predetermined orientation relative to the first x axis, the first y axis, or the first z axis.

摘要： Various embodiments are directed to a method and system for mapping or visualizing the magnetic fields and their associated field strengths of an object, such as a mobile computing device. An example source of the magnetic fields may be a near-field communication (NFC) reader configured in the object. A computer vision system or device may track a visual marker arranged near or on a magnetic field strength detector in order to associate, match, or map the magnetic field strength measurement readings of the detector at different positions or locations on the object. The computer vision system may generate and display a heat map of the object based on at least the magnetic field strength measurements and their relative positions.

摘要： A metal detection apparatus that can accurately and automatically determine whether a metal passing through the inspection area is a magnetic or non-magnetic metal comprises a detection unit quadrature-detecting a differential detection signal of magnetic field fluctuation in the inspection area due to the passage of a workpiece, and a determination unit that determines the presence or absence of a mixed metal based on both fluctuation components after the detection. The determination unit compares sample signal phase data obtained beforehand from the detection signal of the magnetic field fluctuation in the inspection area due to the passage of various metal samples, with the signal phase data obtained from the detection signal of the magnetic field fluctuation in the inspection area due to the passage of the workpiece mixed with metal, and determines the type of metal passing through the inspection area based on the phase determination result.

摘要： An exemplary method of indicating a condition of grout within a post-tensioned tendon involves positioning a magnet and a metallic sensing plate in close proximity to an outer surface of the post-tensioned tendon; rotating the magnet and the metallic sensing plate around the outer surface of the post-tensioned tendon; measuring an amount of magnetic forces applied to the magnet during rotation of the magnet around the post-tensioned tendon; measuring an impedance between the metallic sensing plate and metallic strands within the post-tensioned tendon during rotation of the metallic sensing plate around the post-tensioned tendon; and generating an image of a cross-section of the post-tensioned tendon indicating one or more grout conditions in spatial proximity to the metallic strands within the post-tensioned tendon based on measurement data using the magnet and the metallic sensing plate.
