  • Patent number: 12379534
    Abstract: A cover for an infrared detector and a method of fabricating the cover are disclosed. The cover comprises a wafer comprising a material such as silicon that transmits infrared radiation. The wafer has a first surface and a second surface opposite the first surface. An antireflective region is formed in the wafer to enhance transmission of infrared radiation through the cover. The antireflective region comprises a first plurality of antireflective elements such as moth-eyes formed in the first surface. The first plurality of antireflective elements are sized and shaped and arranged relative to one another to form a region of graded refractive index at the first surface so as to reduce the amount of infrared radiation reflected by the cover at the antireflective region. The cover comprises a wall extending from the first surface and surrounding the antireflective region.

  • Patent number: 12273344
    Abstract: A communication method, apparatus, and system are provided, to resolve problems in a conventional technology that an AKMA authentication procedure is complex and signaling overheads are large. Principles of the method are as follows: In a registration procedure of a terminal device, AKMA authentication is implicitly indicated based on primary authentication. For example, if primary authentication succeeds, it may be considered that AKMA authentication also succeeds. In addition, an AKMA temporary identifier is allocated to the terminal device after AKMA authentication succeeds. According to the method, apparatus, and system in this application, no additional AKMA authentication is required. This simplifies a procedure and reduces signaling overheads.
