  • Publication number: 20200379213
    Abstract: A prism module of a camera lens includes a fixed holder, a rotary holder, a prism mounted on the rotary holder, a rotation driver assembly provided between the fixed holder and the rotary holder, and a circuit board. The rotary holder includes a base and a rotation driver bracket. The rotation driver assembly is made of memory alloys and deformed, under control of an electrical signal transmitted from the circuit board, to drive the base to rotate. The base and the rotation connecting bracket are directly connected to each other, simplifying the structure of the prism module and reducing the production cost of the prism module. The rotation driver assembly drives the rotary holder and the prism to rotate relative to the fixed holder, in such a manner that the prism can be driven by the rotation driver assembly to automatically correct its angle, thereby providing clearer imaging effect.

  • Publication number: 20200382971
    Abstract: The disclosure provides a method of operating a communication network. The method includes receiving input data related to a state of the communication network and determining an implementation policy for the communication network based on the input data. The implementation policy is a set of features for forming one or more communication links in the communication network over a time interval. The one or more communication links includes at least one communication link between a terrestrial terminal and a high-altitude platform terminal. Determining the implementation policy is based at least in part on utility values of previous policies. The utility values of previous policies are derived using simulation and/or real-world implementation of the previous policies. The communication network is then operated to implement the implementation policy in the time interval.

  • Patent number: 10810512
    Abstract: Machine learning models used in medical diagnosis should be validated before being deployed in order to reduce the number of misdiagnoses. Validation processes presented here assess a performance of the machine learning model pre-deployment. In one or more examples, prior to the deployment of the machine learning model, the validation process assesses (1) whether a model achieves high enough performance to be deployed, and (2) that the process by which the performance metrics were computed was both sanitary and comprehensive. This pre-deployment validation helps prevent low-performing models from being deployed.
