  • Patent number: 11035091
    Abstract: A transportation device for an offshore platform, including a vessel and a floating structure which are fixedly connected. The floating structure is placed on a sea surface and is configured to assist the vessel to sail. The floating structure is provided with an adjustment mechanism which is configured to adjust the floating structure to rise and fall relative to the sea surface. A rail is arranged on the vessel and is in sliding connection with the topside module, so that the topside module slides onto the vessel from land. During the transportation of the topside module, the buoyancy of the floating structure is adjusted through the adjustment mechanism, so that the floating structure provides sufficient anti-rolling moments beside the vessel, thereby reducing the vibration of the topside module caused by the winds and waves during the sailing and reducing the potential damage to the topside module.

  • Patent number: 10795113
    Abstract: An imaging device, an imaging apparatus, and an electronic device for imaging are disclosed. The imaging device includes an imaging sensor that operatively captures an image along an optical axis. The imaging device also includes a lens assembly, and the lens assembly includes a first lens and a second lens. The first lens and the second lens at least partially overlap each other in a first direction parallel to the optical axis. The lens holder operatively adjusts a relative arrangement between the first and second lens to focus the image on the imaging sensor.

  • Patent number: 10027899
    Abstract: An optical module that achieves an adjustable aperture with a multilayer liquid crystal diaphragm, and an electronic apparatus using the optical module are described. The optical module includes at least one diaphragm layer having a light-transmission area that is fully transmissive and a variable light-transmission area filled with material having variable transmittance; and an electrode unit for applying an adjustment voltage to the at least one diaphragm layer. Transmittance of the variable light-transmission area varies in accordance with the adjustment voltage applied by the electrode unit.

  • Patent number: 9781334
    Abstract: A control method, a camera device and an electronic equipment are provided in the disclosure. After acquiring a first control instruction, the lens of the camera device is controlled to perform a preset operation according to the first control instruction, until a preview image captured by the camera device meets a first preset requirement. The preset operation at least includes controlling the lens to form a first inclination angle with respect to an initial position of the lens. Thus the angle between a lens plane and an image plane is adjusted, i.e., the clarity at various parts of the image acquired by the camera device is adjusted, thus a target image desired by a user can be acquired by the camera device, thereby improving user experiences.

  • Publication number: 20170026599
    Abstract: An arrangement method of an image sensor array includes forming an M-row N-column non-standard rectangular pixel array with M×N image sensors, wherein the non-standard rectangular pixel array matches to optical distortion of an associated lens. The non-standard rectangular pixel array refers to that four edges of the non-standard rectangular are curves, and the M, N are an integer larger than or equal to 1. An image sensor array, an image acquisition component, and an electronic device are also described.
