  • Publication number: 20200400941
    Abstract: A head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting or casting. The spacers are disposed on one or more major surfaces of the waveguides and define a distance between immediately adjacent waveguides. Adjacent waveguides may be bonded using adhesives on the spacers. The spacers may fit within indentations of overlying waveguides. In some cases, the spacers may form one or more walls of material substantially around a perimeter of an associated waveguide. Vent holes may be provided in the walls to allow gas flow into and out from an interior volume defined by the spacers. Debris trapping structures may be provided between two walls of spacers to trap and prevent debris from entering into the interior volume.

  • Publication number: 20200387600
    Abstract: An attack defense method and apparatus for a terminal, a terminal, and a cloud server. Before a client application (CA) communicates with a secure application (TA), a secure execution environment such as a trusted execution environment (TEE) verifies scenario feature information, such as screen touch information, corresponding to a current operation of the client application, to determine whether the operation is an actual operation of a user or a hacker attack. If the operation is a hacker attack, there is no screen touch information. If there is a risk of a hacker attack, communication between the client application and the secure application is not established, so that the client application cannot run properly, and an attempt initiated by a hacker to discover a system vulnerability is blocked.
