Abstract: The present invention provides a wireless network-based positioning method and positioning apparatus. The positioning method includes: obtaining time information used for determining a current location of a to-be-positioned node, where the time information records times of arrival of a first sounding signal determining time differences of arrival of the first sounding signal at the at least three anchor nodes according to recorded historical information and the time information; and determining the current location of the to-be-positioned node according to locations of the at least three anchor nodes and the time differences of arrival of the first sounding signal at the at least three anchor nodes. By means of the present invention, time differences of arrival of a sounding signal at different anchor nodes can be accurately determined, thereby determining an accurate location of a to-be-positioned node and avoiding synchronization between the anchor nodes.

Abstract: This application provides a hearing monitoring method and apparatus. The method includes: obtaining ear overuse information of a user, where the ear overuse information includes accumulated duration and/or accumulated times of overuse of ears of the user; and generating prompt information or a control instruction based on the ear overuse information. In this solution, because accumulated information is obtained, impact of a misoperation of the user can be excluded, and continued overuse of ears is also fully detected. Therefore, an unnecessary or missed reminder is avoided, thereby achieving more accurate hearing monitoring effect.

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.
