Abstract: An exoskeleton device including an exoskeleton with a base section, a support section movably coupled to the base section for supporting a body part of the human body, and an actuator device acting on the support section for providing a support force for the body part. The exoskeleton device further includes a sensor device for detecting a risk variable which includes a movement of the support section and/or a force and/or a pressure between the support section and the body part, and a control device for controlling the actuator device. The control device is configured to detect a risk state on the basis of the detected risk variable, in which risk state there is a risk of health impairment and/or damage, and to initiate a safety measure in response to the detection of the risk state, which comprises outputting a warning signal and/or counteracting the risk state.

Abstract: Circular saws having a blade that moves relative to a stationary base structure during operative use of the circular saws to cut a workpiece and methods of detecting a kickback condition of such circular saws. The circular saws include a base structure, a user-actuated assembly, an attachment structure, and a controller. The attachment structure is configured to permit constrained relative motion between the base structure and the user-actuated assembly in a motion direction and during operative use of the circular saw to cut the workpiece. A motion sensor is configured to generate a motion signal indicative of motion of the user-actuated assembly along the motion direction. The controller is programmed to initiate a kickback response of the circular saw responsive to the motion signal being indicative of a kickback condition of the circular saw.

Abstract: A sawing device containing a base part for supporting the sawing device on a base surface and a slide is provided. The slide is mounted on the base part so as to be displaceable in a translational manner via a linear guide. The sawing device includes a saw head which is rotatably mounted on the slide. A drive unit for rotationally driving a saw blade in a saw blade plane (S) is arranged on the saw head. In addition, at least one interface for selectively coupling an electrical energy storage device is arranged on the slide. The interface is electrically connected to the drive unit. Moreover, a saw assembly containing such a sawing device and at least one electrical energy storage device is presented. The electrical energy storage device is coupled to the sawing device via at least one interface.

Abstract: Power tools and methods of operating power tools are disclosed herein. The power tools include a motor including a motor shaft configured to rotate about a shaft rotational axis. The power tools also include a sensor assembly configured to generate a differential voltage signal that is indicative of a distance between an individual and a cutting tool being less than a threshold distance. The sensor assembly also is configured to produce a sensor assembly output that is based upon the differential voltage signal. The power tools further include an analysis circuit configured to receive the sensor assembly output and to generate a trigger signal responsive to the sensor assembly output being outside a nominal sensor assembly output range. The power tools also include a mechanical reaction mechanism configured to insulate the individual from the cutting tool responsive to receipt of the trigger signal.
