  • Publication number: 20240397218
    Abstract: A position detection device includes: a first magnetic field generator generating a first magnetic field; a driver opposed to the first magnetic field generator in a first-axis direction; and a magnetic field sensor detecting the first magnetic field. The driver causes the first magnetic field generator to move in a second-axis direction parallel to a first plane orthogonal to the first-axis direction. The first magnetic field generator is movable in the second-axis direction with respect to the driver and the magnetic field sensor. The driver is spaced from and overlaps a part of the first magnetic field generator in the first-axis direction, and extends across the part of the first magnetic field generator in a third-axis direction parallel to the first plane and orthogonal to the second-axis direction. A center position of the magnetic field sensor in the third-axis direction is different from that of the first magnetic field generator.

  • Patent number: 11580132
    Abstract: A cloud computing system, which works in cooperation with a plurality of relay devices, is configured to receive measurement data transmitted from each of the relay devices arranged in respective bases and perform accumulation processing in a hierarchical structure of a logical tree form in a measurement database, and perform aggregation analysis processing on the measurement data subjected to the accumulation processing in the respective bases and for each integration target between the bases. The aggregation analysis processing is performed on the measurement data for the each integration target between the bases by recognizing a relationship between the bases under the same starting point on the basis of a measurement unit of a measurement value or a type of a measurement source as for the value in the source accumulated in the database as an ending point of the hierarchical structure.
