  • Patent number: 11363882
    Abstract: A reading book stand mainly comprises a base plate (1) and a support plate (2) and a clamp (3). An intersecting line divides a length (L) of the base plate into two parts (L1) and (L2). A reading angle (A) is not less than 90 degrees. This is applicable for a book in which the vertical forward direction of text on pages having the text of the main text part is nearly perpendicular to the spine of the book and points toward the fore edge of the book that is nearly parallel to the spine of the book.

  • Patent number: 10038685
    Abstract: Methods and apparatuses for service request authentication are disclosed to prevent a terminal or a first server that does not sign an agreement with a gateway from bypassing the gateway to directly access a second server. The method includes receiving a service request and determining a session in which the service request is located; determining whether a token corresponding to the session exists, the token corresponding to a session in which a service request from a gateway is located; if the token exists, determining that the authentication of the service request passes and proceeds to process a corresponding service; if the token does not exist, determining that the authentication of the service request fails and the processing of the corresponding service is refused. Thus, since only a session corresponding to service requests forwarded by the gateway can have a token, the authentication of each service request that belongs to such session will pass.
