Abstract:
1. A combustion tool having a circuit for conserving battery power comprising: a battery assembly, the battery assembly configured to power at least a portion of the combustion tool; a control circuit coupled to the battery that is configured to place the combustion tool in an active mode or a low power consumption mode; and a motion sensing circuit coupled to the control circuit that is configured to indicate a movement of the combustion tool and to indicate a non-movement of the combustion tool to the control circuit, wherein the control circuit is configured to place the combustion tool in the active mode upon the movement of the combustion tool and to place the combustion tool in the low power consumption mode after a period of time after the non-movement of the combustion tool, and wherein the control circuit immediately provides power from the battery to the combustion tool when movement of the combustion tool is detected by the motion sensing circuit.
