  • Patent number: 10680676
    Abstract: Various embodiments associated with signal conversion while underwater are described. A source can transmit an alternating current signal with a relatively high frequency over a relatively long distance. The alternating current signal with the relatively high frequency can be converted to an alternating current signal with a relatively low frequency. An example of this conversion can be done by converting the alternating current signal with the relatively high frequency into a direct current signal. The direct current signal can then be converted into the alternating current signal with the relatively low frequency. The alternating current signal with the relatively low frequency can be transmitted from a transmission coil to a pick-up coil. After reception by the pick-up coil the alternating current signal with the relatively low frequency can be processed, such as processed to determine a direction of the source of the alternating current signal with the relatively high frequency.

  • Patent number: 10670425
    Abstract: A system for determining angular position includes a dipole magnet having an axis of rotation, wherein the dipole magnet produces a magnetic field. A first magnetic field sensor produces a first output signal and a second magnetic field sensor produces a second output signal in response to the magnetic field. The magnetic field sensors are operated in a saturation mode in which the magnetic field sensors are largely insensitive to the field strength of the magnetic field. Thus, the first output signal is indicative of a first direction of the magnetic field and the second output signal is indicative of a second direction of the magnetic field. Methodology performed by a processing circuit entails combining the first and second output signals to obtain a rotation angle value of the magnet in which angular error from a stray magnetic field is substantially cancelled.

  • Patent number: 10656121
    Abstract: Provided are a method and device for detecting arrangement disorder of fibers in a conductive composite material. A coil (7) is disposed at a position at which the coil (7) faces the conductive composite material, and thereby a current can be applied to the conductive composite material. Thus, work or the like for attaching electrodes to the conductive composite material is not required. As a result, the arrangement disorder of the fibers in the conductive composite material can easily be detected. A method for detecting meandering of fibers in a conductive composite material includes a step of disposing a magnetic field sensor (8) at a position at which the magnetic field sensor (8) faces a surface (Sa) of the conductive composite material such that a direction (D) of a magnetosensitive axis is horizontal with the surface (Sa) and is parallel to coil faces (7e).

  • Patent number: 10649015
    Abstract: A method may include applying an excitation signal to a capacitor of the capacitive sensor which causes generation of a modulated signal from an input signal indicative of a variance in a capacitance of the capacitor, detecting the modulated signal with a detector to generate a detected modulated signal that has a phase shift relative to the excitation signal, demodulating the detected modulated signal into an in-phase component and a quadrature component using a reference signal, nullifying the quadrature component by setting a phase of the reference signal relative to the excitation signal to compensate for the phase shift, and outputting the in-phase component as an unmodulated output signal representative of the capacitance.

  • Patent number: 10649037
    Abstract: The invention relates to insulation fault location systems and methods for insulation fault location for an ungrounded DC power supply system, which is redundantly fed from a first direct voltage supply source coupled to diodes and a second direct voltage supply source coupled to diodes and to which a consumer is redundantly coupled. Due to the diode coupling and the asymmetric current splitting of the load current associated therewith, non-compensational partial currents arise in the supply lines in such a power supply system and consequently differential current portions, which can be captured by measuring current transformers and which can interfere with a valid test current during an insulation fault location. In order to eliminate the interfering differential current portions, compensating measures on the primary side are proposed in the measuring current transformers and indirect compensating measures on the secondary side are proposed in an insulation fault location apparatus.

  • Patent number: 10648886
    Abstract: In adjustment processing executed at the same period as waveform analysis processing, a CPU of a microcomputer permits an execution of the waveform analysis processing on condition that the waveform analysis processing has been completed. Thus a period of non-execution of the waveform analysis processing is ensured between a completion of preceding waveform analysis processing to an execution of next waveform analysis processing. Since low priority processing, which has been disabled to be executed, is enabled to be executed, it is possible to stop continuation of disablement of execution of the low priority processing.

  • Patent number: 10634520
    Abstract: A modular sensing system for determining the relative lineal position between a first object and a second object includes an array of switch units fixed with the first object and an array of magnet units fixed with the second object. Each switch unit contains an electric circuit that includes a switch, a resistor, and conductors arranged to convey electricity from one of a pair of front connectors to one of a pair of rear connectors, and from the other front connector to the other rear connector through either the resistor or the switch when the switch is closed. The switch is normally open but closed when proximate one of the magnet units, each of which houses a magnet. Resistance between a pair of wires of a first switch unit in the array is related to the relative linear position between the arrays of switch units and magnet units.
