Abstract: A content transmission method includes obtaining, by a first terminal device, a first instruction instructing the first terminal device to perform content transmission with a second terminal device sending, by the first terminal device, to the second terminal device, and in response to the first instruction, first information instructing the second terminal device to determine that that the first terminal device transmits content to the second terminal device. Receiving, by the first terminal device, content transmission direction indication information from the second terminal device, determining, by the first terminal device, first content, and sending, by the first terminal device, the first content to the second terminal device to display the first content.

Abstract: This application provides a signal decoding method, a decoding circuit, and a stylus. One example method includes: sampling a to-be-measured signal based on a predetermined sampling rate to obtain a plurality of sampled signals, where the to-be-measured signal is a modulation signal that carries an interference signal, and the modulation signal is sent by a touch panel of a terminal device; determining at least two edge signals in the to-be-measured signal based on the plurality of sampled signals; and decoding the to-be-measured signal based on the at least two edge signals to obtain the modulation signal.

Abstract: An electronic product protective case includes a rear housing and a holder which further includes a magnet assembly, and the magnet assembly includes a first magnet group and a second magnet group. The first magnet group includes a first magnet and a third magnet that have opposite polarities. The second magnet group includes a second magnet and a fourth magnet that have opposite polarities. The first magnet and the second magnet have opposite polarities. The third magnet and the fourth magnet have opposite polarities. The first magnet and the second magnet are mutually absorbed, and the third magnet and the fourth magnet are mutually absorbed.
