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

Patent number: 6119046Abstract: Depending on the desired direction of current flux through an electrical load such as a stepped motor, in a measuring bridge circuit provided with switchable semiconductors and recovery diodes the semiconductors through which the current direction is switched are closed, causing the actual current to increase until it has attained the nominal current value, whereupon switching is effected into either slow current decay mode or fast current decay mode. A selection of the operating mode is made at the next semiconductor switch-on such that, if the actual current value is greater than the nominal current value at the next semiconductor switch-off, fast current decay mode is selected, and if the actual current value is lower than the nominal current value, slow current decay mode is selected.Type: GrantFiled: February 2, 1998Date of Patent: September 12, 2000Assignee: Deutsches Zentrum fur Luft-und Raumfahrt e.V.Inventor: Norbert Sporer
