The invention relates to a method for determining an optimal frequency of an oscillating movement of a force-accelerated projectile of an intracorporeal pneumatic lithotripsy apparatus, including the following steps: repeatedly accelerating the projectile from a first proximal stop of an acceleration path to a second distal stop, and from the second stop to the first stop, wherein a piezo element is arranged between a proximally arranged counter bearing and a distally arranged horn and is mechanically coupled to the counter bearing and to the horn, and the horn has a distally arranged sonotrode, wherein the acceleration path is arranged in the interior of the counter bearing and of the horn and the first stop is arranged at a distal end of the counter bearing and the second stop is arranged at a distal end of the horn, detecting an electrical signal from the piezo element caused by a tremor at the first stop and/or the second stop as a result of the projectile; and using the detected electrical signal to control a medium which generates the force and which is used to accelerate the projectile from the first stop of the acceleration path to the second stop, and from the second stop to the first stop.

An illumination device for an endoscope includes illumination means for coupling light into a light guide. The illumination means has an LED matrix array having a plurality of LED pixels forming an emission area, and further includes a light guide port associated with the illumination means for positioning a light-guiding transmission area, which is disposed at an end of the light guide. The device also includes LED pixels configured as sensor elements configured to detect LED pixels of the emission area that are directed at non-light-guiding portions of the light guide, and wherein the device has a control unit which is configured to selectively operate the LED pixels of the LED matrix array for coupling light into the light guide in such a manner that at least some of the LED pixels directed at the non-guiding portions of the light guide in the main emission direction are operated at lower power or deactivated.

The invention relates to an endoscopic device, in particular medical or industrial endoscopic device, wherein the endoscopic device comprises, as components, a light source, an optical fiber, a camera, and an endoscope comprising an optical element or a plurality of optical elements, and at least one optical element comprises an optical marking for verifying an identity of the optical element and/or of the endoscope such that the optical marking can be detected by the camera for verifying the identity and/or a configuration of the endoscopic device. The invention furthermore relates to a method for verifying an identity of a component of an endoscopic device, and a computer program product for evaluating an image acquisition of an optical marking of an optical element and for identifying an endoscope of an endoscopic device.
