摘要： An apparatus and methods are described for protecting an operator from sudden, unexpected or dangerous movement of powered hand held tools and the like. A set of parameters for safe operation of the tool are provided, which parameters may be adjusted or selected based on the manner in which the tool is being operated. The power tool is fitted with sensors including an accelerometer, operating to sense acceleration of the tool in a plurality of axes during operation. The output of the accelerometer is coupled to a computing circuit which determines if the acceleration of the tool is within the safe operation parameters. When acceleration of the tool exceeds one or more of the safe operating parameters, power to the tool motor is limited or otherwise adjusted in order to prevent or reduce the movement of the tool thereby protecting the operator.

摘要： A detection means 1 detects changes in impedance generated at a coil TC caused in response to indentations Py1 and Py2 and projections provided at the surface of a movable portion Rot to generate a detection signal thereof. A speed judgement circuit 2, to which the detection signal from the detection means is provided, continuously generates a high level output signal A2i when the detection signal e change interval becomes greater than a specific length of time. A level detection circuit 3, to which the detection signal e is provided, generates a high level output signal A1i when the detection signal e is at or above a specific level. An AND circuit 4, to which the output signal A2i from the speed judgement circuit 2 and the output signal A2i from the level detection circuit 3 are provided, generates an output signal Z resulting from AND calculation of the two output signals A1i and A2i. The delay in notification of movable portion stop is reduced and notification of movable portion stop is issued based upon verification that the coil TC is combined with the movable portion Rot in a normal manner and also verification that the movable portion Rot has been monitored until immediately before the stop of the movable portion Rot.

摘要： In an apparatus for detecting tip-over of a rammer equipped with a crankcase accommodating an output shaft rotatably connected to an engine, a movable unit accommodating a converter mechanism for converting rotation of the output shaft to vertical motion of a movable member, a tamping shoe connected to the movable unit, and a handle operable by an user, and adapted to thrust upward in the gravitational direction by the vertical motion of the movable member and go into a free fall to compact a ground surface, it is determined whether a detected engine speed becomes equal to or smaller than a threshold value set lower than an engine idling speed when the engine has been operated at a rammer working speed set greater than the engine idling speed, and if it does, it is discriminated that the rammer has tipped over.

摘要： In a method for controlling an electric machine tool having an electric motor for driving a rotating insertion tool, the electric machine tool is operated in one of multiple operating modes, and at least one parameter of the machine tool is detected. The instantaneous operating state of the electric machine tool is ascertained and evaluated based on the detected parameter. A protective function is activated when the presence of a critical operating situation is recognized during the evaluation of the instantaneous operating state. The instantaneous operating mode of the electric machine tool is detected, and the evaluation of the instantaneous operating state is adapted in each case to the instantaneous operating mode.
