Patent number: 7109678Abstract: In a holding arrangement (101) for a medical-optical instrument (103), an electric motor is provided in a rotational joint (111, 119) to compensate a load torque occurring in this rotational joint. This electric motor is supplied with current in correspondence to a detected position of the rotational joint (111, 119). A current control curve required for this purpose is stored in a memory. This current control curve can be determined in that the rotational joints are deflected with the electric motor into predetermined positions and the current demand needed therefor is detected.Type: GrantFiled: June 30, 2004Date of Patent: September 19, 2006Assignee: Carl-Zeiss-StiftungInventors: Martin Kraus, Hartmut Gärtner, Martin Poxleitner, Michael Wirth, Alfons Abele, Roland Brenner, Norbert Sporer, Matthias Hähnle
