599207 Disclosed is a combustion tool having a circuit for conserving battery power. The tool includes a battery assembly (501) to power at least a portion of the combustion tool, a control circuit (512) to place the combustion tool in an active mode or a low power consumption mode, and a motion sensing circuit (502) to indicate a movement of the combustion tool and to indicate a non-movement of the combustion tool. A timer (506) is set when a vibration or a tilt movement is detected and resets each time a new vibration or movement is sensed. If a new vibration or movement is not sensed when a predetermined amount of time has elapsed, the combustion tool enters into a low power consumption mode. The motion sensing circuit (502) enables the tool to be actuated without any unnecessary priming when motion is sensed and only minimal current is consumed when motion is not sensed, conserving battery power. |
