Abstract: A method for externally controlling and managing a wireless local area network subscriber assigned to at least one wireless local area network includes requesting a service using the subscriber, checking an authorization of the subscriber to access the TCP/IP network, and establishing a connection via the TCP/IP network to the subscriber if the subscriber has the authorization to access the TCP/IP network. Signaling and/or information data are managed using a control and managing device connected to the public TCP/IP network via an interface device.

Abstract: The tool and the tool holder each have two sections (18, 19, 20, 21) with different cross-sectional sizes arranged axially one behind the other. These sections (18, 19, 20, 21) on the tool shaft (3) and in the tool holder (1, 2) form reciprocal bearing surfaces. The first section (18) on the tool shaft (3) and the first section (20) of the tool holder (1, 2) have rotationally driving and locking means (5, 11, 12, 13, 14, 15, 16) which are operatively connected in a reciprocal manner. A tool and a tool holder are provided which are very compact and wear-resistant. To this end, the rotationally driving and locking means (5, 11, 12, 13, 14, 15, 16) are arranged in parallel in the axial direction of the shaft (3) and/or the tool holder (1), and they are arranged in series relative to each other in the circumferential direction.

Abstract: For an eccentric disk sander (1, 101, 161) with a housing, in particular a multi-part housing (3, 103, 9, 109, 162, 165), in which a motor with a motor shaft (16, 116, 170) moves a sanding disk (13, 113, 167) via an eccentric (19, 119, 173), in which arrangement the eccentric (19, 119, 173) carries the sanding disk (13, 113, 167) gyrating about the rotational axis (18, 118, 172) with the eccentricity "e", and simultaneously rotating about the spindle (26, 126, 177), the task of providing a compact, robust, and convenient unit is solved by the hollow shaft (19, 119, 173), open at both ends, being designed with an eccentric hole (25, 125, 176), beyond which an eccentric shaft (27, 127, 178) which carries the sanding disk (13, 113, 167) protrudes from at least one end.
