The first and second positioning units match each other.

A positioning jig (10) is equipped with a drive unit (11) and a positioning unit (12) and is placed over a position sensor (1), and the positioning projections (22 to 24) of the positioning unit (12) are engaged in neutral position grooves.

The system also comprises a first positioning device (18, 20) and a second positioning device (19, 21).

In one embodiment of the present invention, a positioning system is provided with a first acquisition unit, a second acquisition unit, and a positioning unit.

The first positioning unit has one x-direction guide bar, and the second positioning unit has two x-direction guide bars.

The sealing unit covers the edges of the proton-exchange membrane, and comprises a first positioning unit and a second positioning unit.

The lens holder includes a lower base, an intermediate member, an upper plate member, a first location adjusting unit, and a second location adjusting unit.

The system (20a) includes a transceiver (56), a positioning unit (38), and a controller (22).

The X-ray device has a detector which is arranged on a movable unit and is assigned to a first positioning unit, and an X-ray source arranged on an arcuate second positioning unit.

The auxiliary system comprises an operation unit (2), a positioning unit (3), a processing unit (4) and a display unit (5).

The instrument comprises a camera, positioning unit, distance measuring unit, lens arrangement and control unit.

The instrument comprises a camera, positioning unit, distance measuring unit, lens arrangement and control unit.

A novel position calculation method that combines the use of the measurement results of a satellite positioning unit and an inertial positioning unit is proposed.

This invention relates to a positioning system for positioning a positioning unit along a longitudinal axis.

According to the invention the positioning unit is characterised by comprising means for determining a rolling movement and an orientation thereof.
