  • Patent number: 10693224
    Abstract: A radio-wave transmitting cover is configured to be arranged in the path of the radio wave of a radio-wave radar device. The thickness of the cover is set to a reference thickness at a reference position where the incident angle of the radio wave from the radio-wave radar device is 0°. The reference thickness is set to a value obtained by multiplying half of the wavelength of the radio wave by an integer. In the area around the reference position, the thickness of the cover is gradually changed such that the greater the distance from the reference position, the greater becomes the difference by which the thickness of the cover is larger than the reference thickness.

  • Patent number: 10666828
    Abstract: An image forming apparatus includes a display section, a display controller, a reading section, an image detector, and a determining section. The display controller controls the display section. The reading section reads multiple documents placed on a specific surface of the image forming apparatus in a batch and generates whole image data indicating a whole image as a result of reading. The image detector detects document images corresponding to the documents based on the whole image data. The determining section determines whether or not batch reading of the documents has succeeded based on a result of detection of the document images. The display controller controls the display section such that the display section displays the document images in a first display format when the determining section determines that the reading has not succeeded, or in a second display format when the determining section determines that the reading has succeeded.
