Abstract: A facial recognition method for video conferencing requiring a reduced bandwidth and transmitting video and audio frames synchronously first determines whether a 3D body model of a first user at a local end has been currently retrieved or is otherwise retrievable from a historical database. Multiple audio frames of first user are collected and audio frequency at a specific range are filtered out. An envelope curve of the first audio frames and multiple attacking time periods and multiple releasing time periods of the envelope curve is calculated and correlated with lip movements of first user. Information packets of same and head-rotating and limb-swinging images of the first user are transmitted to a remote second user so that the 3D body model can simulate and show lip shapes and other movement of the first user.

Abstract: The invention provides a fetal movement monitoring system which uses optical pattern sensing to detect fetal movements. Fetal movements provide a change in the optical path between the optical sensor and detector, such as a different proportion of amniotic fluid and fetus and/or a different contact pressure with the optical sensor arrangements. One or both of these effects may be detected based on analysis of the optical signals captured by the system.
