  • Publication number: 20200319423
    Abstract: A camera lens module includes a lens assembly. The lens assembly may comprise a first optical lens module comprising a first carrier and at least one first optical lens received in the first carrier; and a second optical lens module comprising a second carrier, at least one second optical lens received in the second carrier, and a bearing portion connected to the second carrier. When the first optical lens module and the second optical lens module are assembled together, an adjustable clearance exists between the first carrier and the bearing portion, and between bottom surfaces of the first carrier and a lowermost lens of the first optical lenses and a top surface of an uppermost lens of the second optical lenses.

  • Patent number: 10782593
    Abstract: A lens module and a capturing module integrating a focusing mechanism and an assembly method therefor. A lens module (1010) comprises at least one optical lens (1011), a focusing mechanism (1012), and a supporting structure component (1013). Each optical lens (1011) is mounted in an accommodating cavity of the supporting structure component (1013) in a height direction of the supporting structure component (1013). The supporting structure component (1013) is connected inside of the focusing mechanism (1012) as a carrier of the focusing mechanism (1012). The supporting structure component (1013) moves as the focusing mechanism (1012) is powered, and is thereby suitable for focusing. By replacing a carrier and a lens cone of a conventional focusing mechanism with the supporting structure component (1013), an overall assembly process is simplified, the yield and quality of a module are improved, and the manufacturing costs are reduced.

  • Patent number: 10750437
    Abstract: A method and system for proactively managing a base station neighbor list. A base station or other network node tracks changes to the base station's neighbor list and identifies a recurring pattern of changes, in correspondence with a particular time of day for instance. The base station or other node then proactively changes the base station's neighbor list in anticipation of a recurrence of the identified pattern, such as in anticipation of recurrence of the time of day for instance. Advantageously, this method can help to reduce the extent to which the base station engages in an automatic neighbor relation process, and thus reduce the extent of signaling and other issues associated with engaging in that process.

  • Patent number: 10548063
    Abstract: A wireless device or UE is configured to function as a relay on behalf of a donor access node. The relay UE performs call admission controls including balancing the resources of the relay access node with the resources provided by the donor access node providing services to end UEs via the relay access node, i.e. a backhaul connection of the relay UE. The backhaul throughput is compared to a throughput requirement of the end UEs being served by the relay UE. If the throughput requirement is larger than the backhaul throughput, any new connection requests from an additional end UE may be rejected. A threshold may be defined to ensure that there are ample resources at the backhaul prior to accepting connection requests from additional end UEs.
