  • Publication number: 20220107498
    Abstract: The invention provides smart glasses having expanding eyebox, which includes a projector and at least one beam translation module. The projector provides an image beam, which is polarized. The at least one beam translation module is disposed on a path of the image beam, and includes an adjustable liquid crystal panel and a birefringent crystal plate. The adjustable liquid crystal panel is disposed on the path of the image beam and configured to adjust an amount of phase retardation of the image beam. The birefringent crystal plate is disposed on a path of the image beam from the adjustable liquid crystal panel. After the amount of phase retardation of the image beam is adjusted through the adjustable liquid crystal panel, a translation in a direction parallel to a beam-emitting surface of the birefringent crystal plate occurs on the image beam exited from the birefringent crystal plate.

    Abstract: Examples pertaining to flexible radio access technology (RAT) selection for 5th Generation (5G) mobile communications are described. A user equipment (UE) may receive, from a network node of a wireless network, information related to a RAT preference with respect to RAT selection by the UE. Based at least in part on the received information, the UE may perform a RAT or Public Land Mobile Network (PLMN) selection procedure. Alternatively, or additionally, the UE may receive, from the network node, information related to ability of one or more neighbor network nodes of one or more RATs in a region. Based at least in part on the received information, the UE may select one of the one or more RATs or one of the one or more neighbor network nodes.
