Abstract

The present invention is a method for transmitting a RFID signal while conserving battery power of a circuit. The method comprises charging a capacitor using a battery. The battery is in electrical communication with a resistor and the resistor is in electrical communication with a capacitor and a load switch. The load switch is in electrical communication with an enabler and a microprocessor. The microprocessor is in electrical communication with a radiofrequency component. The load switch is closed, allowing power drawn from the capacitor to flow to the radiofrequency component.

Claims (8)

1. A method for transmitting a RFID signal while conserving battery power of a circuit, the method comprising:

charging a capacitor using a battery, the battery in electrical communication with a resistor, the resistor in electrical communication with a capacitor and a load switch, the load switch in electrical communication with an enabler and a microprocessor, the microprocessor in electrical communication with a radiofrequency component, wherein the resistor controls the rate at which the capacitor is charged from the battery in order to conserve power;

closing the load switch to power the microprocessor and the radiofrequency component, the power drawn from the capacitor;

transmitting a signal from the radiofrequency component, wherein a peak current of transmission of the signal is limited to 2 milliamps;

receiving a confirmation signal at the radiofrequency component, wherein the radiofrequency component operates at 2.4 giga-Hertz;

opening the load switch; and

recharging the capacitor at a controlled rate;

wherein in order to conserve battery power, the radiofrequency component transmits a signal until the confirmation signal is received or until a threshold number of signals are sent from the radiofrequency component without a confirmation signal, the threshold number of signals ranging from 5 to 50.
