  • Patent number: 10712369
    Abstract: Embodiments of the present disclosure provide mechanisms for measuring currents flowing in one or more conductor wires. The mechanisms are based on using magnetic sensor pairs arranged within a housing with an opening for the wires, where each magnetic sensor pair can generate a pair of signals indicative of magnetic fields in two different directions. The outputs of the sensor pairs can be used to derive a measure of current(s) flowing through the one or more wires. The use of magnetic sensor pairs that can measure magnetic field in two different directions may enable simultaneous current measurement in multiple wires placed within the opening, improve accuracy of current measurements while relaxing requirements for precise control of the placement of the wire(s), reduce the impact of stray magnetic interference, and enable both AC and DC measurements.

  • Patent number: 10698054
    Abstract: A method and a system for magnetic resonance imaging are provided. The method includes acquiring a magnetic resonance (MR) data set of an object by sampling only a portion of a k-space of the object. This sampled portion may be substantially triangle-shaped or be composed of multiple planes that extend through a point of origin of the k-space and are tangential to a common spherical cap in the k-space. An inverse Fourier transformation is then applied to the MR data set to transform the MR data set from the k-space to image space. A final MR image with a fan- or cone-beam geometry is then computed based on the transformed MR data set in image space.

  • Patent number: 10678668
    Abstract: A device, which may be embedded in a power distribution enclosure, enables analysis of the conditions of an electromechanical machine operating on a commonly supplied network with other electromechanical machines. The analysis preferably uses aggregate operating voltage and current signals supplied to or from such machines along with known changes in steady-state conditions of one or more machines to discern the discrete effect of one or more machines to the aggregate electrical signal. Such discrete effect can then be associated with the operating performance of the individual machine. And, since such voltage and current signals are normally readily available at the enclosure, wiring or any other communication means to any sensors on the electromechanical machines or devices are not necessary. The embedded device may optionally receive or transmit information to a computing or monitoring device remote from the enclosure.

  • Patent number: 10677859
    Abstract: Embodiments relate to magnetoresistive sensors suitable for both angle and field strength sensing. In an embodiment, a sensor comprises two different magnetoresistive (xMR) sensor components for sensing two different aspects or characteristics of a magnetic field. In an embodiment, the first xMR sensor component is configured for magnetic field angle or rotation sensing, while the second xMR sensor component is configured for magnetic field strength sensing. In an embodiment, the second xMR sensor component is configured for magnetic field strength sensing in two dimensions. The second xMR sensor therefore can determine, in embodiment, whether the field sensed with respect to angle or rotation by the first xMR sensor component is of sufficient strength or meets a minimum magnitude threshold. If the minimum threshold is not met, an alarm or alert can be provided.

  • Patent number: 10641843
    Abstract: The invention relates to a circuit or microchip for the detection of poor sources of (or very weak) electrical and/or magnetic fields. In one embodiment a device of the present invention includes a microchip consisting of a plate with a plurality of cells, each cell includes a crystal suspended in a semiconducting polymer and piece of metal wire. The cell is insulated by another polymer. A voltage is applied to parallel wires running on each side of the cell, thus inducing a first (or static, or initial) voltage when measured from the cell to the wire. Changes in magnetic or electrical fields are detected by noting a change in voltage from the cell, which is caused by the crystal changing orientation due to the change in the field the circuit is subjected to.
