The invention also relates to a method for adjusting the brightness of such a light source arrangement.

A regulating device for regulating a cooling circuit for the temperature control of a battery system having more than one heating and/or cooling element is described, wherein the regulating device comprises two regulating stages arranged successively.

Each adjusting spindle (20a, 20b, 20c, 20d) serves for the relative adjustment of two adjusting parts (E) in an appropriate adjusting direction (X, Z, U1, U2).

The adjusting arrangement is configured in the form of a common adjusting mechanism (11) for jointly adjusting the two locking hooks (9).

Each of the two adjusters adjusts a respective one of the two carriers.

The two drive devices have different strokes, throw forces, and throw speeds.

The two control circuits operate independently of each other.

The system comprises at least two adjustment units.

The cartridge 24 comprises two side walls 26, a plurality of roll-lever units 30, two adjusting rings 28 and an adjusting actuator 32.

Both prostheses permit lateral adjustment and adjustment to accommodate interpedicle distance.

Said adjusting mechanism has at least one adjusting possibility, preferably two adjusting possibilities for moving about one axis (x or y) or two axes (x,y) of the co-ordinates system in space.

The adjustment changes anterior-posterior relationship of the two parts.

The two optical engines have an adjustment mechanism for adjusting the position in which the image is displayed.

This results in two regulated systems, wherein the first regulated system regulates the motor/generator and the second regulated system regulates the adjustable guide geometry.

The adjusting system (4) consists of two parts, i.e. an adjusting screw (12) and a spring washer (13) which is disposed between said adjusting screw (12) and the pressure piece (3) and consists of a bearing surface (13a) for the stub (7) free end.
