Abstract: In at least one example, a medical device is provided. The medical device includes at least one therapy electrode, at least one electrocardiogram (ECG) electrode, at least one acoustic sensor, and at least one processor coupled with the at least one acoustic sensor, the at least one ECG electrode, and the at least one therapy electrode. The at least one processor can receive at least one acoustic signal from the at least one acoustic sensor, receive at least one electrode signal from the ECG electrode, detect at least one unverified cardiopulmonary anomaly using the at least one electrode signal, and verify the at least one unverified cardiopulmonary anomaly with reference to data descriptive of the at least one acoustic signal.

Abstract: Sensing devices, systems and methods for securing articles against tampering using a unique magnetic field signature measured at two different times are provided. One or more sensing devices are secured to a ferrous surface portion of a target container. The sensing devices are secured using a plurality of magnets. The unique magnetic field signature sensed by a sensing device is produced by a combination of the plurality of magnets of the sensing device and the ferrous surface portion of the target container and earth's magnetic field. The two different times being one of a baseline measurement session and one of an observation measurement session. An observation measurement session may be triggered by a shock event or periodically.
