Abstract
A handheld unit for an industrial technical system comprising some of the following: a proximity sensor, an acceleration sensor, an orientation sensor, a position-determining device and an image-capturing device. Commands input by a user to the handheld unit and output signals from the modules are fed to an evaluation device in the handheld unit that transmits control commands to a control device in the industrial technical system. The evaluation device compares output signals of the modules to predetermined first signal patterns and transmits commands that activate components in the industrial technical system to the control device only if the command requested and the output signals of the modules match one of the predetermined first signal patterns. Otherwise the evaluation device does not transmit the control commands.

20. A handheld unit for an industrial technical system having multiple activatable components, comprising:
-
a user input device; multiple modules selected from a group including a proximity sensor, an acceleration sensor, an orientation sensor, a position-determining device and an image-capturing device, an evaluation device to which commands are input by the user input device and to which output signals are fed by selected modules, said evaluation device comparing output signals of the modules to predetermined first signal patterns and transmitting control commands that effect an activation of at least one component of the industrial technical system to a control device of the industrial technical system only if a command requesting the activation of said component is input by said user input and the output signals of the modules match a predetermined first signal pattern. - View Dependent Claims (21, 22, 23, 24, 25, 26)
