Circuit for transmitting a RFID signal
The present invention relates to a system for transmitting a signal while conserving battery for a shot tracking device attached to a grip of a golf club. The system comprises a circuit comprising a battery, a resistor, a capacitor, a microprocessor and a radiofrequency component.
1. A circuit for conserving power for a shot tracking device attached to a grip of a golf club, the circuit comprising:
a battery having no more than 75 milliamps of capacity;
a resistor in electrical communication with the battery, wherein the resistor controls a rate at which a capacitor is charged from the battery;
the capacitor in electrical communication with the resistor, wherein the capacitor is a one micro-Farad capacitor;
a load switch in electrical communication with the capacitor, the load switch maintained in an open state until an impact transitions the load switch to a closed state;
a microprocessor in electrical communication with the load switch, wherein when the load switch is in the closed state, current drawn from the capacitor is allowed to flow to the microprocessor;
a radiofrequency component in electrical communication with the microprocessor, wherein when the load switch is in the closed state a signal is transmitted from the radiofrequency component and a confirmation signal is received at the radiofrequency component, wherein the radiofrequency component operates at 2.4 giga-Hertz, wherein a peak current of transmission of the signal which is limited to 2 milliamps;
and the load switch, with no impact, transitions to an open state, thus deactivating the microprocessor and the radiofrequency component and allowing the power to be conserved.
