Abstract: A power-supply mode switching circuit and an aerosol generating device are provided. The power-supply mode switching circuit includes an external-power-source power-supply circuit, a protection circuit, and a battery power-supply circuit. A node where the external-power-source power-supply circuit is connected to the protection circuit serves as a power-source input end. A node where the external-power-source power-supply circuit is connected to the battery power-supply circuit serves as a power supply end. The protection circuit is configured to control the battery power-supply circuit to be cut off when the power-source input end is connected to the external power source, to make the external power source supply power to the power supply end. The protection circuit is further configured to control the battery power-supply circuit to be conducted when the power-source input end is not connected to the external power source, to make the battery supply power to the power supply end.

Abstract: Methods, apparatuses, electronic devices, and readable storage mediums are provided. An example electronic device includes a first radio frequency link and a second radio frequency link. The first radio frequency link includes a component configured to detect an antenna parameter. The second radio frequency link includes a tunable component. An example method includes obtaining first antenna parameter information of the first radio frequency link by using the component that is comprised in the first radio frequency link and that is configured to detect an antenna parameter. The example method further includes tuning, based on the first antenna parameter information by using the tunable component in the second radio frequency link, an antenna corresponding to the second radio frequency link.

Abstract: A photographing method includes receiving a pressing operation performed by a user on a photographing control of the camera application, and determining, based on both an age of the user and pressing duration of the pressing operation, whether to shoot one photo or continuously shoot a plurality of photos.

Abstract: It is suitable for the field of computer graphic processing technologies, and provides a method and apparatus for repairing a graphics processing unit (GPU) video memory access based on active error detection. A small video memory is first distributed and used for error detection of video memory access, and a problem of video memory data access abnormality is found in time through a regular active detection. When the video memory data access abnormality is found, a GPU desktop driving module can suspend a display picture update operation, and a GPU kernel driving module first suspends all video memory access, then re-initializes a video memory controller and repairs the video memory access abnormality, and then restores an access of all the modules to a video memory to normal, refreshes a desktop, and restores a graphic desktop to a normal state.
