Patent ID: 8301232

Claim:
An ECG device comprising: an electrode assembly configured to sense heart-related signals upon contact with a user's skin, and to convert the sensed heart-related signals to ECG electrical signals wherein the electrode assembly is positioned on an outer surface of a smartphone protective case; and a converter assembly including an audio transmitter for outputting frequency modulated ultrasonic signals, the converter assembly integrated with, and electrically connected to the electrode assembly and configured to receive the ECG electrical signals generated by the electrode assembly and output ECG sound signals through the audio transmitter to a microphone in a computing device within range of the audio transmitter, wherein the converter assembly is further configured to output the ECG signals as an ultrasonic FM sound signal, wherein the audio transmitter is configured to output the ultrasonic FM sound signal to a microphone in a computing device within range of the audio transmitter, wherein the output from the audio transmitter is detectable by a microphone in a smartphone when the smartphone is positioned within the smartphone protective case.
