Abstract: A system for analysis of operation of a hand-guided working apparatus, wherein the working apparatus includes a working tool and a drive system for driving the working tool, includes an optical recording device configured for recording a temporal succession of images of a working procedure on a workpiece using the working tool, an identification device configured for identifying a temporal succession of operational data values of the drive system during recording of the temporal succession of images, and at least one output device configured for outputting in each case at least one of the recorded images together with at least one identified operational data value correlated in time thereto.

Abstract: A method for operating a wireless transmitter and a wireless receiver, wherein the wireless transmitter is assigned to a tool and is adapted to detect an operation condition of the tool and to send an operation condition signal as a function of the detected operation condition. The wireless receiver is assigned to an apparatus and is adapted to receive the sent operation condition signal and to control an operation condition of the apparatus as a function of the received operation condition signal. The method assigns the wireless transmitter and the wireless receiver by a user-operated, electric assignment apparatus such that the receiver controls the operation condition of the apparatus as a function of the received operation condition signal. The assignment apparatus is separate from the transmitter and the receiver.

Abstract: A motorized chain saw has a measuring system for measuring an object, in particular a trunk. The motorized chain saw has a saw chain, and the measuring system has an evaluation device. The measuring system includes a sensor system for capturing the movement of the saw chain as the saw chain rolls over an object to be measured. The evaluation device is configured to evaluate the movement of the saw chain captured by the sensor system. In a method for operating the motorized chain saw, the sensor system captures the movement of the saw chain as the saw chain rolls over an object to be measured, and the evaluation device evaluates the captured movement.

Abstract: A device is provided for capturing operating data of a tool, wherein the tool is powered by an electric motor or a combustion engine, and wherein the device is embodied separately from the tool and is able to be coupled to the tool. The device includes: an operating data sensor, which is configured to wirelessly capture operating data of the tool, an operating data memory, which is configured to store operating data captured by the operating data sensor; and a communication interface, which is configured to wirelessly transmit operating data stored in the operating data memory to a terminal device.

Abstract: A turbomachine having a wall that extends circumferentially to a central axis of the turbomachine at least in certain areas, and having at least one insert device that can be connected in a releasable manner to a wall in the area of a recess which is arranged inside the wall. The insert device has a connection device by means of which the insert device can be brought into operative connection with a connection device of the wall. The connection device of the insert device has a projection that extends in the radial direction of the turbomachine at least in certain areas in the mounted state of the insert device, and that in the mounted state of the insert device meshes in a groove of the connection device of the wall. The connection device of the wall has a projection that extends in the radial direction of the turbomachine at least in certain areas in the mounted state of the insert device, and that, in the mounted state of the insert device, meshes in a groove of the connection device of the insert device.
