A Real-time DSP-Based Ringing Detection and Advanced Warning System

Epilepsy in itself is a brain disorder, in which the normal pattern of neuron electrical activity becomes disturbed, causing abnormal problems to the patients. This paper explains the DSP-based real time system for a patient who suffers from these types of recurrent bouts with sound induced epileptic seizures. Specifically, sounds that are produced by telephone (rotary, cellular) rings and pagers. It should be noted, however, that this patient has the ability to block the effect of the trigger by merely being aware that the ring is about to occur. The basic idea behind this real-time DSP based system is that, it could receive the sounds heard by the patient mentioned above with a microphone and deliver a visual signal or on vibrator worn by him, providing an advanced warning of an incoming ring.
