Abstract: A defibrillator system and associated methodology for determining capacity of a battery and/or a number of battery cells contained in a pack. The system measures and stores the battery or battery pack voltage signal data and uses an algorithm to determine the remaining capacity. The algorithm takes into account the operating mode of the device, historical information of the device including, but not limited to, how long it has been since the device has been used, how the device has been used (e.g. shocking mode or idle mode), how many times the device has been used with its installed battery or battery pack, how many charging cycles and/or shocks have been delivered etc. The output from the system is fed back to the user to inform the user when the battery is low, needs to be replaced and/or how many remaining shocks are left the battery.

Abstract: An automatic external defibrillator with an intelligent self-test system that ensures device readiness. The self-test system conditionally runs functional tests based on knowledge of device use, time of day, pre-programmed information, operational features and previous events. The condition of the defibrillator is indicated visually, audibly or both based on the results of the self-test performed.

Abstract: A method and system for expediting the rescue of victims experiencing sudden cardiac arrest (SCA) when used in conjunction with an automated external defibrillator (AED). The system involves an apparatus that calls for help (i.e. 911), detects SCA and cardiac arrhythmias, locates an AED, guides the rescuer through CPR and connection of the AED. A second apparatus is in the enclosure that contains the AED, sends location information to the other apparatus, triggers audible and visual indicators, and provides information on the victim's location.

Abstract: A Wireless Monitoring Apparatus is used in conjunction with an automated external defibrillator (AED) system for patient rescue in mass-casualty incidents. The rescuer applies the device on each patient. The wireless monitoring apparatus automatically analyzes the patient's heart rhythm and communicates with the AED system. The AED system is therefore is able to display information with regard to each patient, notifies the rescuer on actions to take and can deliver defibrillation therapy if needed.
