摘要： Woodworking machines including conductive cutters adapted to cut workpieces, and motors adapted to drive the cutters are disclosed. The machines also include a contact detection system adapted to detect contact between a person and the cutter, and to distinguish contact between the person and the cutter from contact between the workpiece and the cutter. The machines further include a reaction system adapted to cause a predetermined action to take place upon detection of contact between the person and the cutter by the contact detection system.

摘要： A woodworking machine including a detection system adapted to detect a dangerous condition between a person and a working portion of the machine is disclosed. The machine includes a reaction system associated with the detection system to cause a predetermined action to take place relative to the working portion upon detection of the dangerous condition. A motion detection system is adapted to detect motion of the working portion and to disable the reaction system when the working portion is not moving. The motion detection system may include a sensor, such as a Hall effect sensor, an electromagnetic field sensor, an optical sensor, or an electrical sensor. The woodworking machine may take the form of a saw, the working portion may be a blade adapted to cut when spinning, and the dangerous condition may be a person contacting the blade.

摘要： A method of controlling a woodworking machine having a movable cutting tool. The method monitors a signal for a change indicative of a dangerous condition between the cutting tool and a person, senses movement of the cutting tool, and performs an action to mitigate the dangerous condition when the signal change and movement of the cutting tool are both detected. A woodworking machine including a detection system adapted to detect a dangerous condition between a person and a working portion of the machine and then to perform some action to mitigate the dangerous condition is also disclosed. A motion detection system is adapted to detect motion of the working portion and to disable the reaction system when the working portion is not moving.

摘要： A circuit for continuously monitoring or determining the magnitude of a resistance, capacitance, inductance, voltage or current over a very large dynamic range by means of a signal-to-pulse-train converter, rather than by conventional linear amplification techniques. The circuit in part, comprises a resistance, current or voltage source, and a reactive element. The reactive element is discharged from the power source to operate a temperature insensitive trigger circuit that, in turn, actuates a semiconductor switch recharging the reactive element. The frequency or period of operation is a preselected function of the variable parameter to be determined, as of a transducer.
