  • Publication number: 20230076726
    Abstract: An electronic control unit for a vehicle includes processing circuitry configured to determine first cryptographic information based on a private key of the electronic control unit and based on a public key of a second entity. The processing circuitry is further configured to obtain second cryptographic information via an interface, and to compare the first cryptographic information and the second cryptographic information. The processing circuitry is also configured to unlock a control access to the electronic control unit if the second cryptographic in formation is based on a private key of the second entity and based on a public key of the electronic control unit.

  • Patent number: 10663040
    Abstract: An enhanced method and precision nanopositioning apparatus for implementing enhanced nanopositioning performance is provided. The nanopositioning apparatus includes a vertical linear nanopositioning flexure stage and a horizontal linear nanopositioning flexure stage. The vertical linear nanopositioning flexure stage includes a stage base, a symmetrically configured flexure linear guiding mechanism with precision motion enhancement structure, and a stage carriage. The horizontal linear nanopositioning flexure stage is mounted on the stage carriage of the vertical linear nanopositioning flexure stage, and includes a middle-bar relative position control mechanism to enhance the stiffness of a flexure linear guiding mechanism.

  • Patent number: 10393242
    Abstract: A method and apparatus for implementing an ultra-high stability long-vertical travel stage are provided. The ultra-high stability long-vertical travel stage includes a first wedge supporting a second wedge, each wedge formed of a selected stable material having predefined rigidity and low thermal expansion coefficient, and integrated air bearings. A linear guiding mechanism includes a plurality of flexures. The first wedge is driven in a plane providing vertical motion on the second wedge with the integrated air bearings lifted and the flexures allowing for movement.

  • Patent number: 9613729
    Abstract: An enhanced mechanical design of multiple zone plates precision alignment apparatus for hard x-ray focusing in a twenty-nanometer scale is provided. The precision alignment apparatus includes a zone plate alignment base frame; a plurality of zone plates; and a plurality of zone plate holders, each said zone plate holder for mounting and aligning a respective zone plate for hard x-ray focusing. At least one respective positioning stage drives and positions each respective zone plate holder. Each respective positioning stage is mounted on the zone plate alignment base frame. A respective linkage component connects each respective positioning stage and the respective zone plate holder. The zone plate alignment base frame, each zone plate holder and each linkage component is formed of a selected material for providing thermal expansion stability and positioning stability for the precision alignment apparatus.
