The tool includes a driving unit to be activated with power supplied from a power source. The image capturing unit is provided for the tool and generates a captured image. The orientation detection unit is provided for the tool and detects an orientation of the tool. The processing unit performs processing based on the captured image and the orientation.

An electric tool adapted to perform tightening operations where torque is delivered in pulses to tighten a screw joint. The electric tool including an electric motor drivingly connected to an output shaft. A processor and a memory storing software instructions that, when executed by the processor cause the electrical tool, retrieve a first power level parameter p1 indicating a first power level to be used for torque pulses up to a torque threshold. And retrieve a second power level parameter p2 indicating a second power level to be used for torque pulses above the torque threshold. Then control the speed of the electric motor, so that the electric tool provide torque pulses on the output shaft with the first power level p1 until the torque threshold is reached. And control the speed of the electric motor, so that the electric tool provide torque pulses on the output shaft with the second power level p2.

A power tool and method of detecting impacts of a power tool that includes a motor driving a hammer to impact an anvil. A motor control unit is configured to determine a motor characteristic indicative of a speed of the motor. When the motor characteristic indicates that the speed of the motor is below a speed threshold, the motor control unit employs an acceleration-based technique to detect a first impact based on a change in motor acceleration and generate a first impact indication in response to detecting the first impact. When the motor characteristic indicates that the speed is above the speed threshold, the motor control unit employs a time-based technique to detect a second impact based on an elapsed time and generates a second impact indication in response to detecting the second impact.
