Abstract: The present disclosure relates to a lighting device, comprising a device body and a locking device on both of which magnets magnetically attracted to each other are provided respectively; the device body comprises a controller and a detection module connected to each other, the detection module is configured to detect a connection state between the device body and the locking device, and the controller is configured to control the device body to be in a locked state when the connection state is a magnetic connection state.

Abstract: Disclosed is a text data attribution description and generation method based on text character features, comprising: obtaining text data to be processed, decomposing the text data to obtain a plurality of characters, and performing a feature space representation on the text data based on the characters; storing the features of the text data through a horizontal position of the characters and an association between different characters according to the feature space representation of the text data; generating a text data attribution according to feature storage results of the text data.

Abstract: A graphics processing method and apparatus, and relates to the field of chip technologies. The method includes: obtaining a first virtual address to be accessed by the GPU, where the first virtual address belongs to a first virtual address space; and obtaining a second virtual address based on the first virtual address, where the second virtual address belongs to a second virtual address space. The second virtual address space is different from the first virtual address space, the second virtual address space and the first virtual address space are mapped to a same physical address space, a physical address to which the first virtual address is mapped corresponds to image data in a first format, and a physical address to which the second virtual address is mapped corresponds to image data in a second format.
