Title: SYSTEMS AND METHODS OF POWERING CIRCUITS WITH NEAR END-OF-LIFE BATTERIES
Abstract:
The present application discloses systems and methods of powering a solenoid circuit and other circuits with batteries that are at (or near) the end of their functional life. The solenoid is powered by an inductor feeding a capacitor via a diode, controlled by a switch to boost the voltage of the capacitor. The boosting allows use of a 1.5V battery depleted to 1.1 VDC or below.
