Abstract: A camera holder (3) is provided for fixing a camera (11) or a camcorder to an optical observation device. The holder (3) has a variable-length sleeve (13) with a first end configured to receive the camera objective and a second end configured to secure the sleeve (13) relative to the optical observation device. The holder (3) also has an adjusting device (19) fixed to the sleeve (13). The adjusting device (19) has a pin for connection with a stand mating thread of a camera (11) and is configured to compensate for an offset between the stand mating thread and the camera objective. The adjusting device (19) enables the camera (11) to be positioned with respect to the sleeve and the optical observation device.

Abstract: The invention relates to an arrangement for at least partially compensating a torque caused by gravitational forces acting on a mass body (2), which is rotatably supported on an axis of rotation (3). The arrangement includes a gas pressure spring (5) for providing a linear force. This linear force is transformed into a torque by means of a converter unit (7). The mass body (2) and the converter unit (7) can be coupled to each other in a way which allows for adjusting the amplitude and the phase of a compensating torque.

Abstract: An adjusting device (3) is suitable especially for use on a stand (1) for a surgical microscope (2). The adjusting device (3) makes it possible to move the surgical microscope (2) in a plane (9) perpendicular to the optical axis (8) of the surgical microscope (2). For this purpose, a transmission is provided in the adjusting device (3) which includes a coupling plate which is operatively connected to two force-transmitting elements. When this transmission is moved, at least one of the force-transmitting elements rolls off on the coupling plate. Alternatively, this transmission can be built up as a four-point linkage chain or contain a rhombic mechanism or lever mechanism. It is also possible to configure the transmission with belt elements or to configure the same as an eccentric arrangement having two offset rotation centers.

Abstract: 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.

Abstract: A medical therapy and/or diagnosis equipment has a position sensing device that cooperates, for sensing of respective position or orientation of the medical therapy and/or diagnosis equipment, with a further sensing device that is separated by a signal path from the position sensing device and is fixed in position and orientation. The position sensing device is constructed as a position sensing arm that extends away from the medical therapy and/or diagnosis equipment.
