Abstract:
1. A method for transmitting a wireless signal from a device while conserving battery power of the device, 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 less than 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.
