  • Patent number: 10837985
    Abstract: An apparatus for measuring an electric current through a bus bar comprises a compensation coil and a magnetic field sensor. The bus bar has a through-hole dividing the electric current flowing through the bus bar into at least two partial currents flowing around the through-hole. The compensation coil is disposed in the through-hole and generates a compensation field. The compensation field compensates a plurality of magnetic fields generated by the partial currents and/or an external magnetic field such that a magnetic flux density of a resulting magnetic field at a predetermined position of the through-hole does not exceed a predetermined threshold. The magnetic field sensor is disposed in the through-hole and detects the magnetic flux density of the resulting magnetic field at the predetermined position. The magnetic field sensor emits an output signal corresponding to the detected magnetic field.

  • Patent number: 10837986
    Abstract: A microelectronic device has a common terminal transistor with two or more channels, and sense transistors in corresponding areas of the channels. The channels and the sense transistors share a common node in a semiconductor substrate.

  • Patent number: 10838021
    Abstract: The present disclosure relates to apparatuses and methods to utilize techniques to simultaneously measure Ramsey pulses on a plurality of axes of the magneto-optical defect center material with defect centers. When measuring simultaneously, there is potentially no relative sensitivity loss relative to scalar measurements. Therefore, Ramsey pulses on a plurality of axes of a magneto-optical defect material with defect centers are measured while bypassing the sensitivity loss incurred with sequential measurement techniques. The axes are interrogated simultaneously while allowing for isolation of the individual responses from the signal detected from the magneto-optical defect center material. In some embodiments, the system utilizes a special Ramsey pulse sequence pair or a ‘shifted magnetometry adapted cancellation’ (SMAC) pair to detect and measure the magnetic field acting on the system.

  • Patent number: 10838024
    Abstract: A self-calibrating solid-state magnetometer for vectorized field sensing via zero-field spin-dependent recombination is realized with a wide band gap semiconductor junction. Three sets of Helmholtz coils provide a cancellation field at low frequency, as well as a modulated field at audio frequencies. The presence of the hyperfine interactions in the zero-field response as well as the low-field electrically detected magnetic resonance detection capability allows for magnetometer self-calibration.

  • Patent number: 10838025
    Abstract: A radio-frequency system for a magnetic resonance apparatus has a local coil, a body coil, and an impedance adjusting shield. The body coil is wirelessly power-coupled with the local coil such that the body coil serves as a transmitting coil for radio-frequency signals and the local coil serves as a receiving coil for magnetic resonance signals. The local coil is disposed in an internal cavity of the impedance adjusting shield. An impedance of the local coil is adjusted by the impedance adjusting shield so as to match the impedance of the local coil and the body coil. The impedance adjusting shield has a frequency modulation element that adjusts the resonance frequency of the local coil. The body coil couples power to the local coil, and the impedance adjusting shield effectively reduces energy transmission efficiency loss caused by reflection, thereby improving energy transmission efficiency.

  • Patent number: 10838031
    Abstract: In a magnetic resonance (MR) method and apparatus, first and second MR data are acquired from respective echo trains with gradient moments of one echo train being in a sequence that is an inversion of at least a portion of the sequence of gradient moments in the second echo train. The MR signals are acquired from at least two substances in a volume of a subject, so that the relaxation of the respective nuclear spins influences the manner by which the first and second data are entered into k-space, so that when an image is reconstructed, the filter effect induced by such relaxation is compensated for.
