Abstract: Characteristics of a user's heart are detected. In accordance with an example embodiment, a ballistocardiogram (BCG) sensor is used to detect heart characteristics of a user, and provide a BCG output indicative of the detected heart characteristics. The BCG output is further processed using data from one or more additional sensors, such as to reduce noise and/or otherwise process the BCG signal to characterize the user's heart function.

Abstract: Certain embodiments of the present disclosure are directed toward devices, methods and systems for controlling depolarization in cardiac cells. One such device includes one or more circuits that are configured and arranged to generate an electrical stimulus at a high frequency. The circuit is configured to provide electrical stimulus over a period of time sufficient to depolarize the cardiac cells. An electrode arrangement is configured and arranged to deliver the high frequency electrical stimulus to cardiac cells and depolarize the cardiac cells.

Abstract: Disclosed is a transdermal electrotransport drug delivery system having a constant current that can accommodate large resistance change in a body surface. A semiconductor circuit component such as a Zener diode or a PMOS FET is used to impose a voltage drop from the output of a voltage booster circuit to maintain a constant current for electrotransport. Methods for its use are also disclosed.
