Abstract: Two connected electronic devices may use a controller and two power converters to share battery charge. The two electronic devices may share charge after one electronic device's battery is completely discharged. In the alternative, the two electronic devices may compare the relative age of the two batteries and if the age difference exceeds a predetermined threshold, the younger battery may share charge until it is insufficiently charged to power both electronic devices.

Abstract: Systems and methods for inhibiting an occurrence of an apneic or hypoxic event are disclosed. Physiological data is received from a subject and analyzed to detect an impending apneic event or an impending hypoxic event. A stimulation is applied to the subject to inhibit occurrence of the impending apneic or hypoxic event after an occurrence of a predetermined condition. The physiological data can include respiratory data, cardiological data, or a combination thereof. The analyzing includes use of a point-process model and gross body movement data of the subject. Therapeutic effectiveness of the stimulation is increased by accounting for gross body movements of the patient.
