Abstract: A method and system for automatically detecting heart sounds. The sound system receives sound data corresponding to beats of the heart. The sound system analyzes the sound data to detect the presence of a heart sound within the beats. The sound system then outputs an indication of the heart sounds that were detected. The sound system may use ECG data to identify various locations (e.g., R peak) within a beat and use those locations to assist in the detection of heart sounds.

Abstract: A thin, substantially planar intelligent battery label for attachment to an exterior surface of a standard battery pack to form an intelligent battery pack having dimensions substantially the same as the standard battery pack. The battery management system is implemented within the battery label as a circuit having a variety of components interconnected by a flex circuit. The components of the battery management system may be located on any desired surface of the standard battery pack so as to minimally interfere with the interoperation of the resulting intelligent battery pack with battery pockets designed to receive the standard battery pack. The battery label may be configured to attach to a wide variety of battery packs through the formation of appropriately placed hinge lines and battery management system components. The battery label is a layered device with battery management circuitry disposed on one surface of a flexible base substrate and covered by an impenetrable outer layer.
