Abstract: A word completion method and apparatus are described. The method is applied to a search scenario and is used to complete an incomplete word entered by a user. The method is based on an improved trie. Hot words are stored in some nodes of the trie. In the word completion method, a target node that matches a character string is searched in the trie, and at least one completed word is output to a user based on a hot word stored in the target node. Word completion efficiency is improved, and a case in which a word is recommended to a user when the user enters an excessively short character string is avoided.

Abstract: This application provides an intelligent control apparatus, including: a control circuit and a detection and heating circuit. The detection and heating circuit includes a detection and heating material. When the detection heating material works in a detection mode, the detection and heating circuit obtains a bioelectric signal of a user by using the detection and heating material. The control circuit instructs, according to the bioelectric signal, the detection heating circuit to switch a working mode of the detection and heating material to a heating mode; and instructs the detection and heating circuit to determine heating duration and/or a heating temperature of the detecting and heating material. The apparatus may be used in the field of artificial intelligence. Through control of the control circuit, the detection heating material can have both detection and heating functions. Intelligent perception of a state of the user is implemented by detecting of the bioelectric signal.

Abstract: A camera module is provided. The camera module may be separately used as a camera, or may be applied to a terminal device such as a mobile phone or a tablet computer, or a vehicle-mounted device. The camera module includes an optical lens component, a light filtering layer, an image sensor and a drive module. The optical lens component is configured to receive a light beam from a photographed object, and transmit the light beam to the light filtering layer. The light filtering layer is configured to move a position under the drive of the drive module, and respectively transmit light signals filtered at different positions to the image sensor. The image sensor is configured to receive the light signals at the different positions from the light filtering layer, and determine image information based on the light signals at the different positions.
