摘要： A concrete cutting chain saw has heretofore been considered a rugged performing tool demanding high horsepower and unavailable to the homeowner having only single phase electrical power (20) for powering such a tool. This has been addressed and resolved by the reduction of chain speed to thereby increase torque for the lower horsepower capability. Chain width and thereby cutting width is also reduced, and cutting implements (42) per cutter are reduced, all lowering power demands and resulting in a smooth concrete cutting chain saw for homeowner use. Also included is a conversion kit (14) for converting available homeowner power tools, e.g. an angle grinder (12) for use as a concrete cutting chain saw.

摘要： In various embodiments, a cutting tool such as a chainsaw may include a cutting member that is movable by an engine, one or more sensors configured to detect one or more of acceleration in a direction parallel to one or more axes of the cutting tool and rotational velocity about one or more axes of the cutting tool, and a microprocessor configured to cause movement of the cutting member to stop in response to receiving one or more signals from the one or more sensors. In various embodiments, a method may include receiving, by a microprocessor of a chainsaw, a signal from a gyroscope configured to detect rotational velocity about one or more axes of the cutting tool, and actuating, by the microprocessor, a braking system of the chainsaw to stop movement of a cutting chain around a perimeter of a guide bar in response to the signal.
摘要翻译：在各种实施例中，诸如链锯之类的切割工具可以包括可由发动机移动的切割构件，一个或多个传感器，所述一个或多个传感器构造成检测一个或多个平行于一个方向的加速度或切割工具的更多轴线以及围绕切割工具的一个或多个轴线的旋转速度;以及微处理器，其被配置为响应于从一个或多个传感器接收到一个或多个信号而引起切割构件的移动停止。在各种实施例中，一种方法可以包括由链锯的微处理器接收来自陀螺仪的信号，该陀螺仪被配置为检测关于切割工具的一个或多个轴线的旋转速度，并且由微处理器致动链锯的制动系统以响应信号停止切割链围绕导杆的周边移动。

摘要： Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters.
摘要翻译：实施例包括适于安装到链锯引导杆的鼻部的磨锐夹具。当安装时，操作者可以将力导向导向杆，从而导致线性导向的致动器将磨锐元件移动成与锯链的切割器接合以磨蚀切割器的切割刃。在各种实施例中，致动器被偏置，使得当不再施加力时，致动器将磨刃元件拉离与切割器的接合。
