Abstract

A device for tracking a golfer'"'"'s shot during a round of golf wherein the device comprises a housing, a battery having no more than 225 milliamp hours of power, a microprocessor and an accelerometer. The accelerometer is preferably a multiple axis accelerometer. The circuit is preferably utilized with a device for shot tracking.

Claims

1. A device for tracking a golfer'"'"'s shot during a round of golf, the device comprising:

a housing;

a battery having no more than 225 milliamp hours of power, the battery positioned within the housing;

a microprocessor positioned within the housing, the microprocessor in electrical communication with the battery, the microprocessor operating during a sleep mode, a sampling mode, an analysis mode, a monitoring mode and a transmission mode;

a multi-axis accelerometer for determining movement, monitoring movement and communicating the movement to the microprocessor, the multi-axis accelerometer positioned within the housing, the multi-axis accelerometer in electrical communication with the microprocessor, the power for the multi-axis accelerometer drawn from the battery, the multi-axis accelerometer only active during the sampling mode, the analysis mode and the monitoring mode;

a radiofrequency component positioned within the housing, the radiofrequency component in electrical communication with the microprocessor, the radiofrequency component operating at 2.4 giga-Hertz, the power for the radiofrequency component drawn from the battery, the radiofrequency component only operable during a transmission mode, transmitting a signal from the radiofrequency component during the transmission mode, the signal comprising data related to the movement monitored by the multi-axis accelerometer;

wherein the circuit is in continuous operation;

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

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

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

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