Abstract
System, methods, and apparatuses produce simulated human physiological waveforms such as electrocardiograph (ECG) and blood pressure signals where the microcontroller and/or digital-to-analog converters may be switched to a lower power-consuming state by programmable instructions and switched on in response to a programmable sleep timer.
