  • Locker system access control
    Patent number: 10504313
    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.

  • Strip coatings for metal components of drive units and their process of manufacture
    Patent number: 6171351
    Abstract: An abrasive coating is formed on the tip of a component of a drive unit for abrading an abradable coating during a stripping operation by thermal spraying a ceramic layer on the component, the ceramic layer being profiled and providing a succession of abrading edges and intermediate spaces between the abrading edges to take up and remove abraded material. The abrading edges can be formed as deposits of ceramic material on the component or, as a ceramic layer applied on a profiled surface etched on the component.
