Abstract: A portable device (1) with at least one optical output device (2) for displaying at least process data of a machine, a robot or a technical process, with at least one input device (3) for at least intervening in the operating functions of the device (1) and/or for operating the machine or robot or technical process, and having a safety switch device (12) for preventing the output of undesirable, unintended control commands for the machine, robot or technical process. The output devices (2) and input devices (3) are connected to a control device (14), which is accommodated in a housing (7) that is unbreakable as far as possible and at least one communication interface (17) is provided to an external control device disposed at a distance away. Several of the input and output devices (2, 3) are functionally combined by means of a touch-sensitive screen (4) in the form of a touch-screen (5) and the touch-sensitive screen (4) extends across substantial regions of the surface of the housing (7).

Abstract: The invention relates to a safety switch unit (1) for electrically controlled machines for use in combination with the actual control elements of the machine control system in a hand-held application or for manual control, with at least one operating element which is displaced relative to a mounting frame (8) in accordance with the switching function desired by a user, which is designed to change the switch status of at least one electric switch element, the safety switch unit (1) having at least one switch position which is maintained only as long as a sufficiently high operating force is applied to the displaceable operating elements.

Abstract: The invention relates to a mobile electronic computer unit (1) particularly of the type of a so-called personal data assistant (PDA) or handheld computer, comprising a software-controlled processor unit (3); at least one storage device (4) connected to the processor unit for storing software modules and/or data to be processed; at least one display device (8) for displaying visually detectable information; and at least one input device (10) for at least influencing the operational functions of the computer unit (1) and/or for inputting data. The display and input devices (8; 10) are preferably functionally combined, structurally superimposing one another as a type of display screen sensitive to touch, e.g. in the form of a touch screen (12). At least one interface (6; 7) designed as an interface of the standard type, is arranged on the housing (2) of the computer unit (1). Said interface is provided for linking it with peripheral electronic and electric equipment such as, e.g. a personal computer.

Abstract: The invention relates to a method of connecting a mobile, electronic control and/or monitoring unit (9) to at least one machine or at least one machine component in a group or a plurality of machines (2) or machine components to be controlled and/or monitored. During a connection or log-on procedure between the control and/or monitoring unit (9) and a co-operating distant point on the respective machine (2), a clear link or log-on connection is set up either by means of interfaces (14, 15) to the selected, wireless direction-finder of the co-operating distant point or alternatively by means of transmitters and/or receivers (16, 17) tuned to a restricted, localized functional or operating range (21).
