Abstract: A locking device for releasable locking with a counter body, having a base body, which is connected together with an add-on element and a connection element, and actuation means. One or more slides are fastened to the actuation means, which exert a relative movement to the locking device, whereby the slides are able to be brought into contact with the locking means and these can be transferred into a counter geometry of the counter body. Here, the actuation means remain in their respective position due to the return springs of the locking means and of the tension resulting therefrom as well as of a frictional resistance between locking means and slides. An automatic securing device is provided as secondary securing, designed as a spring-loaded securing bolt for securing the position of the actuation means and prevents unintentional opening of the locking device.

Abstract: A locking device having a base body, a locking means for locking the base body to a counter body, an actuation means movable relative to the base body, said actuation means being able to be brought into contact with the locking means, and at least one displacement device. Upon actuation of the actuation means, the displacement device automatically moves the actuation means into a locking position. In the locking position, the actuation means is in contact with the locking means and transfers said actuation means into a locking position.

Abstract: The invention relates to a locking device having a base body, a locking means for locking the base body to a counter body, an actuation means movable relative to the base body, said actuation means being able to be brought into contact with the locking means, and at least one displacement device. In the case of actuating the actuation means, the displacement device automatically moves the actuation means into a locking position. In the locking position, the actuation means is in contact with the locking means and transfers said actuation means into a locking position.

Abstract: A method for non-instrument-dependent determination of coordinates of a point imaged using a microscope includes determining, at object-related reference coordinates of at least one imaged reference point in a DICOM coordinate system, corresponding first instrument coordinates of the at least one imaged reference point in an instrument-dependent coordinate system. Using the object-related reference coordinates and the corresponding fast instrument coordinates, a transformation rule convening instrument-dependent coordinates into corresponding coordinates of the DICOM coordinate system is determined. Then, using the transformation rule, second instrument coordinates of an imaged point are converted into non-instrument-dependent coordinates of the DICOM coordinate system.

Abstract: The invention relates to a method and a system for device-independent determination of coordinates of a point (P), displayed by means of a microscope, whereby, firstly, the device coordinates (x1, y1, z1), for the displayed reference point (E1), in a device-dependent coordinate system corresponding to the given object-related reference coordinates (X1, Y1, Z1) of at least one reference point in a DICOM-coordinate system and a transformation rule (? for the conversion of device-dependent coordinates (x, y, z) into the coordinates (X, Y, Z) of the DICOM-coordinate system are determined. Finally, to complete the device-independent coordinate determination, the device coordinates (xp, yp, zp) for a displayed point (P) are converted into device-independent coordinates (Xp, Yp, Zp) of the DICOM-coordinate system, by means of the determined transformation rule ?).
