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 (7)

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 having at least 75 milliamps of power, the battery in electrical communication with a resistor, the resistor in electrical communication with the 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, and wherein the capacitor is a 1 micro-Farad capacitor;

closing the load switch to power the microprocessor and the radiofrequency component upon an impact, the power drawn from the capacitor, wherein the microprocessor and the radiofrequency component only receive power when the load switch is closed;

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, wherein the radiofrequency component continues to transmit a signal until a predetermined event;

opening the load switch thereby removing power from the microprocessor and the radiofrequency component; and

recharging the capacitor at a controlled rate, wherein the resistor allows for charging of the capacitor from the battery at the controlled rate.
