  • Patent number: 12277723
    Abstract: In an electromagnetic environment analysis system 1, a display range determination unit determines a display range in which information relevant to a measurement value is displayed in the image, based on a detection result of a second marker. A position calculation unit calculates a relative position between a first marker and the second marker, based on a detection result of the first marker and the detection result of the second marker. A partition judgment unit judges a partition corresponding to a measurement position in which each of the measurement values is measured in a plurality of partitions to which the display range is sectioned, based on the relative position. A display information determination unit determines information relevant to the display of the partition, based on the measurement value.

  • Publication number: 20250029540
    Abstract: A display apparatus includes a power control circuit and a timing control circuit that supplies a timing signal to a level shifter circuit. In response to reception of a control signal used to transition from a display mode to a pause mode from a host controller, the timing control circuit causes the level shifter circuit to stop outputting a gate signal by transmitting a pause signal to the power control circuit and stopping supplying the timing signal to the level shifter circuit. In response to reception of the pause signal, the power control circuit stops supplying at least part of power to be supplied to the display panel and the level shifter circuit while keeping supplying power to the timing control circuit.

  • Patent number: 12055574
    Abstract: In an electromagnetic environment analysis system, an image creation unit creates an image for displaying information relevant to a measurement value in a position associated with a measurement position of each of the measurement values. A partition judgment unit judges a partition corresponding to the measurement position of each of the measurement values in a plurality of partitions forming a display range of the information relevant to the measurement value in the image, based on position information. A display information determination unit determines information relevant to the display of the partition, based on the measurement value corresponding to the partition. In a case where two or more measurement values measured at timings different from each other correspond to one partition, the display information determination unit calculates a representative value from the two or more measurement values, and determines information to be displayed in the partition, based on the representative value.
