Patent ID: 8758262

Claim:
An asthma monitoring system, comprising: a sound sensing device that detects sound over at least a portion of the audible spectrum and converts the detected sound to a sound signal; an acceleration sensing device that detects acceleration and converts the detected acceleration to an acceleration signal; an output device; and a computation module, operably connected to the sound sensing device, the acceleration sensing device, and the output device, the computation module comprising: a memory, containing instructions for processing the sound signal and the acceleration signal, wherein the instructions comprise at least one algorithm that converts a time waveform of the sound signal into a frequency representation and performs time-domain analysis and frequency-domain analysis of at least one of the sound signal and the acceleration signal, and wherein the instructions further comprise an algorithm that measures a spectral-peak-to-noise ratio of the sound signal; a communication module configured to transmit signals to an external device; and a processor module, operably connected to the memory, the communication module, and the output device, and configured to receive the sound signal and the acceleration signal; wherein the processor module retrieves the instructions from the memory, processes the sound signal and the acceleration signal according to the instructions, stores data generated according to the instructions, sends at least one signal generated according to the instructions to the output device, and sends data through the communication module to the external device according to the instructions; wherein the at least one signal is generated based on the frequency representation, the time-domain analysis, the frequency-domain analysis, and the spectral-peak-to-noise ratio.
