Assignee: USA MEDICAL ELECTRONIX, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. An Automated External Defibrillator (AED) device comprising:
a high voltage capacitor (HV Cap) configured to store the energy required to deliver a defibrillation shock to a patient;
one or more batteries configured to charge the HV Cap;
a DC/DC converter circuit comprising a high voltage transformer (HV XFMR), a field effect transistor (FET) switch with associated driver, and a rectifying diode;
an H-bridge circuit configured to transform energy released from the HV Cap into a bi-phasic pulse; and
a memory and a microprocessor which are configured to store and execute computer-executable instructions for operation of the AED device,
wherein the HV Cap, the DC/DC converter circuit, the H-bridge circuit, the one or more batteries, and the memory and the microprocessor are contained in a pocket-sized housing, and
wherein the microprocessor is configured to monitor and adjust the charge rate of the HV Cap so as not to exceed (i) a maximum discharge rate of the one or more batteries, and (ii) a maximum operating temperature of the one or more batteries, thereby enabling the HV Cap to be charged at the maximum rate possible with available battery power.
