  • Patent number: 11907651
    Abstract: The information processing apparatus analyzes the results of modification performed by user for a recommended character string and determines whether there is an excess or a lack in units of predetermined character string areas in a recommended area corresponding to the recommended character string. In a case where it is determined that there is an excess or a lack as a result of the determination, a recommended character string that eliminates the excess or the lack is specified. Then, area information for specifying the recommended area, which is registered in a database, is updated so that the character string corresponding to the specified recommended area becomes the recommended character string.

  • Patent number: 11698519
    Abstract: In an image acquisition device, when capturing an optical image of a sample S through lane scanning, the number of tile images T included in a tile image row R acquired in one lane is counted, and a determination is made as to whether or not the number of images reaches a planned acquisition count that is set in advance. In a case where it is determined that the number of images does not reach the planned acquisition count, lane scanning with respect to the lane is re-executed. Accordingly, even when a loss of the tile images T occurs due to an environment load, the tile images T are complemented by re-execution of the lane scanning, and thus it is possible to prevent the loss of the tile images T in an observation image.

  • Patent number: 11372145
    Abstract: An optical element has a quarter-wave plate formed on the X-Y plane and laminated in the Z-axis direction in three-dimensional space X, Y, Z. The groove in the wave plate is curved, and the angle relative to the Y-axis varies continuously in the range of 0° to 180°. The optical element separates and converts incoming circularly polarized light into light passing therethrough and circularly polarized light reversely rotating a given angle toward the X axis from the Z axis, and outputs the light.

  • Patent number: 11124200
    Abstract: A vehicle control device that is capable of performing abnormality determination of a sensor by majority decision without increasing the number of sensors. A vehicle control device includes a camera and a radar configured to detect a predetermined detection target; and a communication device configured to communicate with outside. The vehicle control device determines whether there is an abnormality in the camera and the radar on the basis of: first acquisition means configured to acquire information on the predetermined detection target from each of the camera and the radar; second acquisition means configured to acquire information, on the predetermined detection target, detected by a road-to-vehicle communication device external to an own vehicle and received by the communication device; information from the camera and the radar acquired by the first acquisition means; and information from the road-to-vehicle communication device external to the own vehicle acquired by the second acquisition means.

  • Patent number: 11125925
    Abstract: To provide a volume-type optical element in which a self-cloning photonic crystal is used. An optical element is provided with half-wave plates of photonic crystals formed on the xy plane and laminated in the z-axis direction in a three-dimensional space x, y, z. The groove direction of the photonic crystals is a curved line, and the angle in relation to the y-axis direction changes continuously in the range of 0°-180°. Light entering the optical element in the axial direction is emitted from the optical element upon being divided and converted into clockwise circularly polarized light in the direction facing the x-axis by a given angle from the z-axis and anticlockwise circularly polarized light in the direction facing the ?x-axis by a given angle from the z-axis. Laminating or placing a quarter-wave plate comprising a photonic crystal on one or both surfaces makes it possible to divide light entering from the z-axis direction of the optical element into two orthogonal linearly polarized lights.
