Abstract: A method for the unique allocation of a first system component (14) of a device system (10), designed as a remote control, to a second and third system component (13, 12) of the device system (10), wherein the remote control (14) can be connected to the second system component (13) via a wireless and cableless communication link (35) or via a first cable or plug connection (36).

Abstract: A method for controlling a device system (10) having a saw blade (14) that is attached to a saw arm (15) and that can be moved along an advancing direction (26) by a motor-driven advancing mechanism (13), whereby there is an infeed motion of the saw arm (15) with the saw blade (14) into the workpiece (18) and, during the infeed motion of the saw arm (15) into the workpiece (18), a control unit (27) calculates an arc length (?) of the saw blade (14) that is engaged with the workpiece (18), and the calculated arc length (?) is compared to a pre-set, critical arc length (?crit) of the saw blade (14).

Abstract: For the automatic determination of the diameter of a tool, particularly a saw blade for an automatic wall saw, which is driven by a motor via a gear unit, the moment of inertia of the tool is used as an indicator for its diameter. Three basic solution variants are introduced. In particular, the system including a motor, gear unit and tool is treated as a dual-mass oscillator such that the elasticity of the shafts and gears is arranged as a torsion spring between the inertial masses in two discrete points while taking into account two coefficients of friction including coefficients of the known inertia of the motor rotor (?R) and of the tool (?S). This system can be described by equations which are then simplified by reasonable assumptions or premises. The selected formulations are solved for the moment of inertia of the tool to determine the diameter therefrom and to make an optimal adjustment for the drive possible which is adapted to the respective tool.
