  • Patent number: 10309992
    Abstract: Apparatus and associated methods relate to a measurement system that calculates a current in a conductor based on an odd-order spatial derivative function of signals representing magnetic-field strengths within a hole in the conductor. In an illustrative embodiment, the odd-order spatial derivative function may generate an output signal representing a spatial derivative of the in-hole magnetic field greater than the first-order. The three or more magnetic-field sensors may be configured to align on the hole's axis when inserted into the hole. When inserted into the hole, the sensors may be aligned on an axis perpendicular to a direction of current flow and be responsive to a magnetic-field directed perpendicular to both the direction of current flow and the aligned axis. Some embodiments may advantageously provide a precise measurement indicative an electrical current in the electrical conductor while substantially rejecting a stray magnetic field originating from an adjacent electrical conductor.

  • Patent number: 10228339
    Abstract: While stripping an electrical cable in a stripping device of a cable-processing system, detection by an electrically conductive cutting device with a sensor circuit takes place if contact with a conductor occurs. By connecting the sensor circuit to the cutting device a measuring capacitance is developed. Before incising the electrical cable, a capacitance value of the measurement capacitance is determined during a first measurement cycle in which a charge equalization is carried out between the measurement capacitance and a reference capacitance. A parameter is determined in a further measurement cycle in which a charge equalization is again carried out between the measurement capacitance and the reference capacitance, wherein, relative to the first capacitance, the parameter displays a change in the capacitance after incising into the electrical cable. A signal is produced, if the change is greater than an established threshold value, indicating contact with the conductor.

  • Patent number: 10222441
    Abstract: During operation, a system may apply an external magnetic field and an RF pulse sequence to a sample. Then, the system may measure at least a component of a magnetization associated with the sample, such as MR signals of one or more types of nuclei in the sample. Moreover, the system may calculate at least a predicted component of the magnetization for voxels associated with the sample based on the measured component of the magnetization, a forward model, the external magnetic field and the RF pulse sequence. Next, the system may solve an inverse problem by iteratively modifying the parameters associated with the voxels in the forward model until a difference between the predicted component of the magnetization and the measured component of the magnetization is less than a predefined value. Note that the calculations may be performed concurrently with the measurements and may not involve performing a Fourier transform.

  • Patent number: 10215720
    Abstract: The present device relates to a sensor capable of detecting changes in the electromagnetic field it generates when in proximity to either conductive or nonconductive materials. This occurs by way of oscillating a transmit coil with an electro motive force at a resonant frequency thus creating an electromagnetic field. The magnetic field passes through a target of either conductive or nonconductive material and is then intercepted by a receive coil which likewise oscillates at a resonant frequency, which when in proximity to the transmit coil and transmit coils resonant frequency produces an enhanced signal by way of the interaction of the respective resonant frequencies and receive coil output.

  • Patent number: 10215822
    Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a processor, and a memory that stores processor-executable instructions. When the instructions are executed by the processor, the instructions cause the processor to give a sample value to at least a part of sampling positions having no sample value in first k-space data so as to create a second k-space data, the first k-space data having a sample value at a part of sampling positions on a k-space. The instructions cause the processor to create a first image from the first k-space data and a second image from the second k-space data. The instructions cause the processor to derive weighting factors for the first image and the second image. The instructions cause the processor to calculate a magnetic resonance image by performing weighted addition using the weighting factors on the first image and the second image.

  • Patent number: 10215831
    Abstract: In a first method and magnetic resonance apparatus to determine a resonance frequency deviation given an excitation of a slice of a volume segment within an examination subject, by a slice selection gradient is activated along one direction, an RF excitation pulse is irradiated in order to excite nuclear spins in the slice, a readout gradient is activated along the direction of the slice selection gradient, and MR data are read out while the readout gradient is activated. Image points within an MR image reconstructed using the MR data are identified, that exhibit a signal intensity that is greater than a predetermined threshold, in order to determine one of the image points that has a maximum separation in the direction between this image point and the slice. The resonance frequency deviation is determined depending on the amplitude of the slice selection gradient, the amplitude of the readout gradient and the maximum separation. The slice selection gradient and the readout gradient have opposite polarity.

  • Patent number: 10209324
    Abstract: A pressurizable holder for a sample to be examined by NMR, comprises a pressure retaining nonmagnetic tube surrounding a radio-frequency coil which in turn surrounds a space for the sample. The pressure retaining tube is formed of (i) nonmetallic electrically insulating material such as a ceramic or (ii) nonmetallic electrically insulating matrix material reinforced with electrically insulating filaments such as glass fiber, or (iii) non-metallic electrically insulating matrix material reinforced with electrically conductive filaments configured so that conductivity is anisotropic. There is good coil filling factor without constraint on wall thickness of the pressure retaining tube. Avoidance of isotropically conductive material inhibits eddy currents when an NMR spectrometer's magnetic field gradient coils are switched on and off. The tube resists hoop stress from internal pressure. Longitudinal stress is resisted by structure connecting end pieces at the ends of the pressure retaining tube.
