Patent ID: 8469714

Claim:
An abdominal breathing training apparatus, adapted for training a trainee how to perform an abdominal breathing, comprising: a belt configured for positioning the abdominal breathing training apparatus around the waist of a trainee and is in close proximity of the abdominal position of the trainee; a sensor unit, disposed in the belt and configured for directly measuring a plurality of abdominal movement signals from the trainee, wherein the sensor unit is positioned securely adjacent to the abdominal portion of the trainee; a data acquisition and conversion unit, electrically coupled to the sensor unit, configured for generating a first trainee abdominal movement waveform according to a measured abdominal movement signals when the trainee performs a normal breathing, generating a second trainee abdominal movement waveform according to a measured abdominal movement signals of the trainee when the trainee performs an abdominal breathing, and generating a third trainee abdominal movement waveform according to a measured abdominal movement signals of the trainee when the trainee performs an abdominal breathing without following any kind of instruction; a trainer unit, configured for: generating a first training waveform for a normal breathing, generating a second training waveform according to the first trainee abdominal movement waveform and an abdominal breathing rule, wherein if the second trainee abdominal movement waveform is determined to be similar to the second training waveform, the trainer unit provides an autonomous breathing indication to the trainee, and determining whether the third trainee abdominal movement waveform is similar to the second training waveform, wherein if the third trainee abdominal movement waveform is determined to be similar to the second training waveform, the trainer unit terminates the training by providing a breathing training completion indication to the trainee via a display unit; and the display unit, electrically coupled to the trainer unit, configured for displaying the training waveforms and the indications to the trainee, wherein the trainee follows the training waveforms on the display unit to perform the abdominal breathing.
