  • Publication number: 20250167070
    Abstract: According to embodiments of the disclosure, a method and an apparatus for determining an interface shape of a heat dissipation cover of a chip are provided. The method includes: determining a first plane warping degree of a flat reference heat dissipation cover after a welding process related to a chip; adjusting an interface shape of the reference heat dissipation cover based on the first plane warping degree, to cause the adjusted interface shape to be opposite to an interface shape reflected by the first plane warping degree; determining a second plane warping degree of the reference heat dissipation cover with the adjusted interface shape after the welding process; and in response to the second plane warping degree satisfying a predetermined condition, determining the adjusted interface shape as an interface shape of the heat dissipation cover.

  • Patent number: 9648019
    Abstract: The embodiments herein relate to a method performed by an AAA server (113) for enabling a non-SIM device (101b) to access a first network (100a) via a second network (100b). Based on a request for authorization to the first network (100a) from the non-SIM device (101b), the AAA server (113) obtains an identity associated with the non-SIM device (101b). The AAA server (113) transmits a request for a user profile associated with a user of the non-SIM device (101b) to the subscriber database (110). The request comprises the obtained identity for the non-SIM device (101b). The AAA server (113) receives, from the subscriber database (110), the requested user profile for the non-SIM device (101b). Based on the received user profile, the AAA server (113) authorizes the non-SIM device (101b) to access the first network (100a) via the second network (100b).
