Patent attributes
Automated External Defibrillator (AED) devices may include a high voltage capacitor (HV Cap) configured to store energy required to deliver a defibrillation shock to a patient; batteries configured to charge the HV Cap; a DC/DC converter circuit including a high voltage transformer, a 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 microprocessor configured to operate the AED device. In particular, the HV Cap, the DC/DC converter circuit, the H-bridge circuit, the one or more batteries, and the memory and the microprocessor may contained in a pocket-sized housing, the AED device may be configured to continuously monitor and adjust the rate at which the batteries charge the HV Cap, and the AED device may include a variable frequency relaxation oscillator circuit configured to acquire a patients Z-body measurement.
