    摘要： Herein a hand-held power tool comprising an internal combustion engine (4) is disclosed. The hand-held power tool comprises, a working tool (6), a centrifugal clutch (8), and a control system (10). The internal combustion engine (4) has a clutch-in speed (ωC) above which the internal combustion engine (4) drives the working tool (6). A speed limitation controller (14), is configured to limit an engine speed at a limitation speed below the clutch-in speed (ωC). The control system (10) is configured to calculate an integral of the rotational speed of the internal combustion engine (4), and to deactivate the speed limitation controller (14) after the integral reaches an integration limit value, such that the internal combustion engine (4) is rotatable above the limitation speed (ωL) to drive the working tool (6) via the centrifugal clutch (8).

    摘要： A hand-held power tool comprising an internal combustion engine (4), a working tool (6), a centrifugal clutch (8), and a control system (10) is disclosed. The engine (4) has a clutch-in speed, above which the engine (4) drives the working tool (6). The control system (10) comprises a rotation speed sensor (12), and a speed limitation controller (14), which is configured to limit an engine speed at a limitation speed below the clutch-in speed. It is active or activated during a starting procedure of the internal combustion engine (4). The control system (10) is configured to deactivate the speed limitation controller (14) upon sensing at least one acceleration at a level above the limitation speed and sensing at least one deceleration at a level above the limitation speed, such that the engine (4) is rotatable above the limitation speed to drive the working tool (6).

    摘要： Arrangement and methods for communicating data between a control system (100) of a power tool (10) and a computing device (20). The arrangement (1) comprises a control system (100) with a plurality of electronic control units, ECUs (110, 120), a computing device (20), and a connecting unit (30) comprising a data connection (32). The plurality of ECUs (110, 120) are connected to a common bus of the control system (100). Each of the plurality of ECUs (110, 120) has a passive service mode (201) and an active service mode (202). The computing device is operable of transmitting a wake-up communication signal to the plurality of ECUs (110, 120), which wake-up communication signal comprises an ID of a selected ECU (110, 120) out of the plurality of ECUs (110, 120). The selected ECU (110, 120) is operable to switch from the passive service mode (201) to the active service mode (202) as a response to detecting its ID in the wake-up communication signal, so as to allow communication of data between the selected ECU (110, 120) and the computing device (20) via the data connection.

    摘要： The present disclosure relates to an implement carrier 1 comprising an implement carrier body 3 driven by a driving arrangement 5 and configured for connecting alternatingly with at least a first 7 and a second 9 implement. The implement carrier further comprises at least one sensor module 11 adapted for scanning at least a portion of the area surrounding the implement carrier 1 and a connected implement 7, 9, such as containing ultrasound sensors and the like. A moveable sensor module arm 13 is provided, having a proximal end 15 connected to the implement carrier body 3, wherein the sensor module 11 is arranged on the sensor module arm at a distance from the proximal end 15. This allows for a flexible placing of the sensor module11 with regard to the implement carrier 1.
