- 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.
