Access to the circuitry is restricted by the bottom surface and dividing layer. A plug is positioned in the dividing layer and has at least one pin that extends through the dividing layer to connect with the circuitry in the circuit enclosure.

Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.

Abstract: AED pulse generation circuits that provide floating, adjustable, bias voltages for driving a solid-state defibrillation waveform therapy generator circuit are provided. The provided bias voltages allow to reverse polarity of provided electric shock to increase chances of successful defibrillation and survival. In one of the provided configurations, energy stored in the pulse capacitor can be discharged by activating the waveform therapy generator in the high-resistance transconductance region. The circuits can be positioned on a self-contained module potted with an insulating material to reduce unintended interactions with other AED components. Through the use of the disclosed circuits, AED size can be reduced to promote pocketability while simultaneously increasing AED reliability.
