The invention relates to a hand-held or semi-stationary setting device (1) for driving fastening elements into a substrate (3) with the aid of a working piston (8), said device comprising a housing with an attachment device (14) at one discharge end (5). In order to simplify the operation of a hand-held or semi-stationary setting device, the working piston (8) is coupled to the attachment device (14) such that when driving a fastening element into the substrate (3), energy of the working piston (8) is absorbed and is transferred to the attachment device (14), in order to press the attachment device (14) against the substrate (3).

A method for anchoring an expansion anchor in a borehole is disclosed. The expansion anchor includes an anchor bolt and an expansion body on a first terminal section of the anchor bolt, an actuator disposed on a second terminal section of the anchor bolt, and an expansion sleeve disposed around the anchor bolt. In an embodiment, the method includes hammering the expansion anchor into the borehole in an insertion direction and actuating the actuator to screw the expansion body outwardly in a direction that is opposite the insertion direction such that the expansion sleeve is expanded radially outwardly and digs into a wall of the borehole and such that the expansion body digs into the wall of the borehole.

The invention relates to a method for setting an expansion anchor by means of a power tool, comprising the following steps: applying rotational impacts to an expansion anchor in accordance with a first rotational speed until a rotational angle per rotational impact of an output shaft of the power tool falls below a predetermined threshold value; and applying rotational impacts to the expansion anchor in accordance with a reduced second rotational speed for a predetermined duration. The invention further relates to a power tool, comprising: an input device for capturing a type of an expansion anchor or a tightening torque for the expansion anchor; an impact unit for producing rotational impacts; a device for sensing a rotational angle of an output shaft; and a control device. The control device is designed to set a first rotational speed, whereby rotational impacts dependent on the first rotational speed can be applied to the expansion anchor until a rotational angle per rotational impact of the output shaft falls below a predetermined threshold value and to set a reduced second rotational speed, whereby rotational impacts dependent on the second rotational speed can be applied for a predetermined duration to the expansion anchor in order to expand the expansion sleeve of the expansion anchor.

A tracking method determines the position 53 of a location 2 marked on a wall 3 using the following steps. The marked location 2 is recorded in a first image 9 using a camera 17 of a mobile measuring station 6, which camera is oriented in a line of vision 18. The image coordinates xO, yO of a first image point (S) onto which the marked location 2 is mapped in the first image 9 are determined. A beam having at least one ray of light 40 is rotated or swivelled through at least one axis 29 of the base station 5, in emission directions 41 that change according to a prescribed procedure, to produce a migrating pattern of points of light 8 on a wall 3 of the interior. A series of images 9 of the wall 3 is recorded in the line of vision 18, with one of the migrating points of light 8 being mapped in the series onto at least one second image point P1, P2. The image coordinates x1, y1; x2, y2 of the at least one second image point P1, P2 are determined. The emission directions 41 of the rays of light 40 whose points of light 8 are mapped onto the at least one second image point P1, P2 at one instant in one of the images 9 are determined on the basis of the instants at which the respective image 9 is recorded. The distance d1, d2 between the axis 29 of the base station 5 and the wall 3 in the emission directions 41 is ascertained on the basis of distance measurements, stored in a reference database 52, from the wall 3 in directions of measurement 44 from the base station 5. The position of the marked location 2 is ascertained on the basis of the image coordinates x0, y0 of the first image point (S), the image coordinates of the second image point P1, P2, the emission direction 41 associated with the second image points P1, P2 and the respective distances (d1, d2) of the axis 29 of the base station 5 from the wall 3 in the associated emission direction 41.

A tracking method determines the position 55 of a mobile measuring station 6 relative to a base station 5 in an interior. The tracking system 1 has a base station 5 and a mobile measuring station 6. The position of the measuring station 6 is determined relative to the base station 5. The base station 5 swivels or rotates a beam having at least one ray of light 40 through at least one axis 29 of the base station 5, in emission directions 41 that change according to a prescribed procedure, to produce a migrating pattern of points of light 8 on a wall 3 of the interior.
