Abstract: A medical device may include an ablation device configured to deliver ablation energy to a treatment site. The medical device may further include a probe device configured to deliver excitation radiation to the treatment site. Further the medical device may include a radiation-receiving device configured to receive photoluminescence radiation emitted from the treatment site in response to the treatment site being illuminated by the excitation radiation and to generate a detection signal in response to the received photoluminescence radiation. Additionally, the excitation radiation may be different from the ablation energy.

Abstract: A measuring method for optically determining a distance (z) of a surface located in a medium from an end of an optical waveguide is described and has the following steps: emitting electromagnetic measuring radiation of a first wavelength (?1) and of a second wavelength (?2) from the end of the waveguide towards the surface, wherein the medium more strongly absorbs the electromagnetic measuring radiation of the second wavelength (?2) than the electromagnetic measuring radiation of the first wavelength (?1); measuring a first reflection signal (I1) of the electromagnetic measuring radiation of the first wavelength (?1) reflected from the surface, and measuring a second reflection signal (I2) of the electromagnetic measuring radiation of the second wavelength (?2) reflected from the surface, and determining the distance (z) from a ratio (I2:I1) of the second and the first reflection signal. Furthermore, a measuring device and a laser lithotripsy device are described.

Abstract: A method is disclosed in which a challenge from a locker system is transmitted to a mobile device. A response is received from the mobile device at the locker system, and the response was generated by a backend system, which received the challenge from the mobile device, at least based on the challenge received by the backend system and on a first key stored at the backend system and has been transmitted to the mobile device. At the locker system, it is checked whether the received response was generated under usage of at least the challenge and a key that corresponds to a second key stored at the locker system. Access is granted to a compartment of the locker system at least depending on a result of the checking. Further disclosed are methods performed by the mobile device and the backend system, and according apparatuses pertaining to these methods.

Abstract: A device for interferential distance measurement that includes a light source that emits a light beam along a propagation direction and a scanning plate including a splitter that splits the light beam into a measurement beam and a reference beam. The device further including a reflector disposed spaced-apart in a direction of the propagation direction and a detector element. The measurement beam and the reference beam are propagated from the splitter along different optical paths toward the reflector, where a back reflection of the measurement beam and the reference beam occurs at the reflector toward the scanning plate. In addition, at a combining location the measurement beam and the reference beam attain interfering superposition, and wherein the measurement beam and the reference beam interfering at the combining location are detected by the detector element so that the detector element generates a distance signal regarding a distance between the scanning plate and the reflector.
