摘要： A computer system receives a plurality of signals corresponding to first time-series magnetic data generated from a plurality of unshielded magnetometers proximate to the human subject. The first time-series magnetic data corresponds to magnetic fields generated from the human subject. The plurality of signals includes contributions from a biomagnetic field from at least a portion of the subject's organ and a background magnetic field. The computer system synchronizes the first time-series magnetic data to a common clock to generate synchronized time-series magnetic data. The computer system applies one or more filters to the synchronized time-series magnetic data to obtain filtered data. The computer system applies one or more noise reduction techniques to the filtered data to generate updated time-series magnetic data.

摘要： A magnetic sensor includes a magnetic sensing device, a sensor housing and a pair of magnetic flux guide members. The sensor housing includes a base body and a flange. The base body holds the magnetic sensing device at one end portion of the base body. The flange is fixed to the base body and is configured to be placed in contact with a receiving wall that receives a first magnetic circuit portion and a second magnetic circuit portion. The flange is made of a material having a higher rigidity than the base body.

摘要： Systems and methods to detect ferromagnetic objects, particularly submerged, non-naturally occurring ferromagnetic objects, account for contributions to the magnetic field arising from topography, such as magnetic refraction at bathymetric slopes. Removing this topography component of noise from detected total magnetic field enhances detection capability of, for example, naval surveillance systems.

摘要： A magnetic sensor device includes at least one magnetic sensor and a support. A center of gravity of an element layout area of the at least one magnetic sensor is deviated from a center of gravity of a reference plane of the support. The at least one magnetic sensor includes four auxiliary resistor sections constituted by a plurality of magnetoresistive elements. The element layout area includes first to fourth areas for laying out the four auxiliary resistor sections, respectively. Two of the first to fourth areas are arranged so that at least parts of the respective two areas sandwich a reference axis therebetween, and other two of the first to fourth areas are arranged so that at least parts of the respective other two areas sandwich the reference axis therebetween.

摘要： A wireless communication system includes a terminal device and a control device that controls a wireless communication device that is used in wireless communication with the terminal device. The wireless communication device includes an electromagnet. The terminal device includes a magnetic sensor. The control device switches on and off the electromagnet. The control device acquires information on a first magnetic field detected by the magnetic sensor from the terminal device, when the electromagnet is off. The control device acquires information on a second magnetic field detected by the magnetic sensor from the terminal device, when the electromagnet is on. The control device estimates a direction from the wireless communication device to the terminal device based on a difference between the first magnetic field and the second magnetic field.

摘要： A computer system includes a chassis comprising location indicating elements, such as springs, magnets, standoffs, or other types of location indicating elements physically attached to the chassis in a configuration that indicates locations in the chassis. Also, the computer system includes multiple printed circuit boards comprising pads configured to interface with the location indicating elements, wherein combinations of sensed or not sensed location indicating elements at the pads of the printed circuit boards provide a physically verified placement location for the printed circuit boards.
