  • Publication number: 20240133208
    Abstract: A locking mechanism includes a first member that is provided on one side to lock and is rotated about a rotating shaft, a second member that is provided on the other side to lock and comes into contact with the first member to rotate the first member, a rotation applying member that further applies a rotational force to the first member rotated by the second member, a restriction portion that restricts movement of the first member to be rotated in a direction in which the first member is released from a locked state, and an elastic portion that allows the first member and the restriction portion to be in elastic contact with each other and allows the first member and the restriction portion to start to be in elastic contact with each other before the first member rotated by the second member is further rotated by the rotation applying member in a release direction which is the direction in which the first member is released from the locked state.

  • Publication number: 20240126202
    Abstract: An apparatus includes a housing, a cover that is opened and closed on the housing, a detection part that detects opening and closing of the cover using ON and OFF, a rotating part that is rotatably supported and turns on and off the detection part, a pushing portion that comes into contact with the rotating part to rotate the rotating part in a case where the cover is closed, and a rotation applying part that applies a rotational force to the rotating part rotated by the pushing portion in a direction in which the detection part is turned on in a case where the cover is closed.

  • Patent number: 8982191
    Abstract: The present invention relates to a method and system for detecting and mapping three-dimensional information pertaining to one or more target objects. More particularly, the invention consists of selecting one or more target objects, illuminating the one or more target objects using a first light source and capturing an image of the one or more target objects, then, illuminating the same one or more target objects using a second light source and capturing an image of the one or more target objects and lastly calculating the distance at the midpoint between the two light sources and the one or more target objects based on the decay of intensities of light over distance by analyzing the ratio of the image intensities on a pixel by pixel basis.

  • Patent number: 8384803
    Abstract: This invention relates to a system and method for creating an omni-focused image. Specifically, this invention relates to a system and method for electronically amalgamating images using real-time distance information to create an omni-focused image. The system of the invention comprises one or more video cameras aimed at a scene each generating a video output focused at a different distance, a distance mapping camera providing distance information for one or more objects in the scene, and a pixel selection utility wherein the pixel selection utility uses the distance information to select pixels from the video outputs to be used to generate a video display. The system is then operable to focus and amalgamate the video outputs to produce one image with multiple focal points or an omni-focused image.

  • Patent number: 7486804
    Abstract: An image of an object illuminated by illumination light having given intensity is formed as an optical image. The distance between respective points of the object is determined on the basis of a video which is obtained by acquiring the optical image with a given image pick-up gain. Here, either the intensity of the illumination light or the image pick-up gain is changed with time. The distribution of intensity of the image acquired by utilization of such intensity or image pick-up gain reflects a time lag between the time at which the illumination light is emitted from a light source and the time at which the light reflected from individual points of the object reaches an image pick-up device. The distribution of intensity includes information pertaining to the distance between the light source and the respective points of the object.
