VIBRATION DELIVERY SYSTEM AND METHOD

摘要

A comfort system for a patient includes a reference generator for generating a reference sinusoid. The reference sinusoid is preferably an 85 Hz sinusoid, that acts as a carrier signal. The reference sinusoid is frequency modulated at a particular sweep rate to produce a frequency modulated sinusoid. The frequency modulated carrier is then amplitude modulated at another sweep rate to produce an AM/FM signal. The AM/FM signal is then provided to a transducer, which provides a vibration by way of a bladder connected to a chair, bed, pillow or the like, in order to provide a soothing affect to a user sitting on the chair. The sinusoids can be created in software using signal processing techniques, or they can be created using hardware components.
