  • Patent number: 11919453
    Abstract: The present disclosure provides a vehicle positioning device for vehicle vision calibration, a positioning adjustment method, and a positioning adjustment system. The vehicle positioning device includes a base, a chassis, a translation mechanism and a rotation mechanism. A to-be-calibrated vehicle is placed onto the chassis, and the chassis is provided with a stopper. The translation mechanism is arranged between the chassis and the base, and configured to drive the chassis to move in an X-axis direction in a three-dimensional coordinate system relative to the base in accordance with a translation control instruction. The rotation mechanism is arranged between the chassis and the base, and configured to drive the chassis to rotate about a Z-axis in the three-dimensional coordinate system relative to the base in accordance with a rotation control instruction.

  • Publication number: 20070026239
    Abstract: Methods of chemical and biochemical functionalization of yarn and textile products are described. A yarn or textile product is contacted with a linker molecule comprising two or more photochemically activatable chemical groups and a non-linker molecule having a desired property. Photochemical activation of the chemical groups causes covalent attachment of the non-linker molecule to the yarn or textile product by means of the linker molecule in a single step. The methods are particularly useful for immobilization to yarn or textile of biomolecules that are susceptible to denaturation. Use of linker molecules derived from proteins or polysaccharides further minimizes denaturation of the biomolecule.

  • Patent number: 5858802
    Abstract: The invention relates to a device including a substrate and at least one biologically active substance bound to at least a part of the surface of this substrate, which is obtained by simultaneous or sequential reaction of said substrate and of said substance with a bifunctional coupling agent in which one of the functional groups is capable of being photoactivated and generates carbenes and is used to bind the coupling agent to the inorganic substrate and the other functional group is used to bind the coupling agent to the biologically active substance, in which said substrate is a covalent inorganic nitride.
