  • Medical therapeutic and/or diagnostic apparatus having a position detecting device
    Patent number: 6804547
    Abstract: The invention is directed to a medical therapeutic and/or diagnostic apparatus having a function unit (1) and a position detecting device (5). A further detecting device (7) is mounted so as to be fixed in position and orientation and is separated from the position detecting device (5) by a signal path. The position detecting device (5) operates together with the additional detecting device (7). The position detecting device (5) can be changed during operation with respect to position and orientation relative to the function unit (1).

  • Stand for mounting various loads
    Patent number: 5667186
    Abstract: A stand is provided for mounting various loads and is balanced at least partially automatically. The stand includes a plurality of interconnected elements defining one or more axes about which the stand is movable. An open-loop or closed-loop control circuit is provided for at least one of the axes and detects the unbalanced state about the one axis. The control circuit allows a torque compensating device to operate on the one axis until a state of equilibrium is obtained.

  • Optical guide system for spatially positioning a surgical microscope
    Patent number: 5345087
    Abstract: An instrument is mounted on a motorized positioning mechanism for providing a contactless guidance of the instrument. A transmitting unit and a receiving unit are arranged in a defined relative position to an operator and the instrument so that an evaluation unit positions the instrument via corresponding control signals with the aid of the registered signals of the receiving unit. A preferred application is the contactless guidance of a surgical microscope which tracks the head movements of the surgeon.
