Abstract: A coin processing device (10) and a method for classifying coins are provided. The coin processing device (10) includes at least one computerized controller (9) having a storage unit (36), and at least one coin channel (34) for guiding a coin (35). The at least one coin channel (34) includes at least one sensor (37) suitable for measuring a passage time of the coin (35). An accelerating device (43) is connected to the computerized controller (9) and is designed to accelerate the coin (35) in a reproducible manner. A target speed value for a specified coin (35) is stored in the storage unit (36). An actual speed value is calculated based on the transport time detected by the sensor (37). A coin class of the coin (35) is ascertained by the computerized controller (9) from the comparison of the target speed value and the actual speed value.

Abstract: The invention relates to a coin processing device (10) and a corresponding method for classifying coins using the coin processing device (10). For this purpose, the coin processing device (10) comprises at least one computerized controller (9), which has a storage unit (36), and at least one coin channel (34) for guiding a coin (35). The at least one coin channel (34) comprises at least one sensor (37) which is suitable for measuring a passage time of the coin (35) and is connected to the computerized controller (9). Furthermore, an accelerating device (43) for the coins (35) is provided, said accelerating device (43) likewise being connected to the computerized controller (9) and being designed to accelerate the coin (35) in a reproducible manner. A target speed value for a specified coin (35) is stored in the storage unit (36), said target speed value being comparable to an actual speed value of the coin. The actual speed value is calculated on the basis of the transport time detected by the sensor (37).

Abstract: A coupling device with a housing (12) and a locking element (11, 11?) for receiving a cylindrical connecting element (18, 18a), whereby an operating element (30) for the releasing of the locking element is accessible by way of an opening in the housing (12, 12?) and whereby the locking element (11, 11?) includes at least one holding portion (26), whereby the locking element (11, 11?) includes a first spring arm (20) with a holding portion (26) which arm extends from the operating element (30) all the way to a wall of the housing (12, 12?) opposite the operating element, whereby the spring arm (20) is constructed at the opposite wall with a joint portion (24). Alternatively, there are two spring arms with joint ends that engage each other.

Abstract: A method and system for registration, authorization, and control of access rights in a computer system. Access rights of subjects on objects in a computer system are controlled using parameterized role types that can be instantiated into role instances equivalent to roles or groups. The required parameters are provided by the subject of the computer system, e.g. by a person, a job position, or an organization unit. Furthermore, relative resource sets are instantiated into concrete resource sets and individual resources by using the same parameter values as for instantiating the role types. Authorization and control of access rights include capability lists providing the access rights of the subjects on the objects of a computer system on a per subject basis. Furthermore, access control lists are derived from capability lists, so that access rights of the subjects on the respective objects are provided.
