Abstract

A method for transmitting a RFID signal while conserving the battery power for a circuit in continuous operation is disclosed herein. The circuit includes a RFID component, a microprocessor, an accelerometer and a battery. The battery preferably has no more than 225 milliamp hours of power. The accelerometer is preferably a multiple axis accelerometer. The circuit is preferably utilized with a device for shot tracking.

Claims (12)

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

activating a microprocessor from a sleep mode to a sampling mode, the microprocessor in electrical communication with a multi-axis accelerometer, a radiofrequency component, and a battery having no more than 225 milliamp hours of power;

activating the multi-axis accelerometer to determine movement during the sampling mode, the power for the multi-axis accelerometer drawn from the battery;

determining with the multi-axis accelerometer if there is movement during an analysis mode;

monitoring movement with the multi-axis accelerometer during a monitoring mode and communicating the movement to the microprocessor; and

transmitting a signal from the radiofrequency component during a transmission mode, the signal comprising data related to the movement monitored by the multi-axis accelerometer, the radiofrequency component operating at 2.4 giga-Hertz, the power for the radiofrequency component drawn from the battery;

wherein the circuit is in continuous operation;

wherein the circuit consumes less than 600 nano-amps during the sleep mode, the sleep mode having a time period ranging from 10 seconds to 30 seconds;

wherein the circuit consumes less than 15 micro-amps during the sampling mode;

wherein the circuit consumes less than 50 micro-amps during the analysis mode;

wherein the circuit consumes less than 200 micro-amps during the monitoring mode; and

wherein the circuit consumes less than 12 milli-amps during the transmission mode.
