Abstract: A message sending method includes: displaying chat messages on a chat interface, which is one of a group chat interface and a single chat interface; when detecting a reply operation performed by a user on a first chat message in the chat messages, obtaining content of the first chat message and content of a reply message corresponding to the reply operation; combining the content of the first chat message and the content of the reply message into a second chat message; when the first chat message is on the group chat interface, sending the second chat message to a client corresponding to each chat account that participates in a group chat; and when the first chat message is on the single chat interface, sending the second chat message to a client corresponding to a chat account that posted the first chat message.

Abstract: The present invention provides a signal processing method and device for the fiber-optic gyroscope, which can effectively expand the dynamic range of the fiber-optic gyroscope, improve the linearity of the scaling factor, and restrain the zero drift of the open-loop fiber-optic gyroscope, i.e., the dynamic fluctuation of the scaling factor. The fiber-optic gyroscope proposed by the present invention provides a first harmonic demodulation reference signal and a second harmonic demodulation reference signal, which are high in quality and synchronous in detection signal, to the signal processing device proposed by the present invention by the digital phase-locked loop technology.

Abstract: A Sagnac phase shift tracking method of fiber-optic gyroscopes comprises determining, for both a current time and a previous time, a value of a primary harmonic demodulated signal and a value of a secondary harmonic demodulated signal from a detector output in the fiber-optic gyroscope; and determining the Sagnac phase shift of the fiber-optic gyroscope for the current time based on the values of the primary harmonic demodulated signal and the secondary harmonic demodulated signal for both the current time and the previous time.
