Abstract: A picture selection method and an electronic device are provided. The method includes: displaying a first interface in an interaction scenario of a first application, where the first interface includes a picture selection button; and displaying a target album interface in response to a first operation performed by a user to trigger the picture selection button, where the target album interface includes thumbnails of at least two pictures that carry different identifier information or at least two picture sets that carry different identifier information; and where identifier information is generated based on interaction scenarios of at least two applications, and the identifier information includes at least one of an application name of an application, time of an interaction scenario of an application, or a quantity of times in an interaction scenario of an application.

Abstract: The system is configured to locate, track and/or analyze activities of living beings in an environment. The system does not require the input of personal biometric data. The sensor system detects infrared (IR) energy from a living being moving in an environment, determines a temperature of the living being based on IR energy data of the IR energy, projects the temperature onto a grid having sequential pixels, determines serial changes of the temperature in the sequential pixels and determines a trajectory of the living being based on the serial changes of the temperature in the sequential pixels.

Abstract: An electric shift actuator includes a case body assembly, a case cover assembly covering the case body assembly, and a gear reduction mechanism assembly arranged in the case body assembly. The gear reduction mechanism assembly includes a motor subassembly, a face gear set, a first-stage gear reduction subassembly, and an output gear assembly configured to be connected to a parking mechanism. An output of the motor subassembly meshes with an input of the first-stage gear reduction subassembly in parallel to form first-stage gear reduction transmission, an output of the first-stage gear reduction subassembly vertically meshes with an input of the face gear set to form second-stage gear reduction transmission, and an output of the face gear set meshes with an input of the output gear assembly in parallel to form third-stage gear reduction transmission. The actuator has functions of emergency parking and manual unlocking with improved safety and redundancy.

Abstract: A network roaming method is provided, this method includes: when a first determination condition is met, a user's SIM card is deactivated and a seed SIM card is activated, and a network registration for the seed SIM card is performed; after the network registration for the seed SIM card is completed, a data dialing is performed on the seed SIM card; after the data dialing is successfully performed, a cloud SIM card allocation request is submitted through a data traffic of the seed SIM card, the cloud SIM card is obtained and activated, and a network registration for the cloud SIM card is performed; after the network registration for the cloud SIM card is completed, a data dialing is performed on the cloud SIM card, the seed SIM card is deactivated and the user's SIM card is activated after the data dialing is successfully performed.

Abstract: A method for switching between different SIM cards for wireless service includes detecting a status of a network used for voice and data and determining if a physical SIM card is a network card in a wireless client. When the physical SIM card is the network card, the method includes determining whether the wireless client includes one or more cloud SIM cards. When the wireless client includes one or more cloud SIM cards, the method further includes detecting a network status of the physical SIM card and assessing whether the network status of the physical SIM card or the status of the network requires using the one or more cloud SIM cards. When the one or more cloud SIM cards are required, the method includes switching the network card from the physical SIM card to the one or more cloud SIM cards.
