Abstract: A method and a system exchange data between a program-controlled device, in particular a microcontroller, and a logic circuit. A control signal is transmitted from the program-controlled device to the logic circuit along a first line. A bidirectionally usable, second line is placed in the dominant state by the logic circuit if a data transmission is to be made by the logic circuit.

Abstract: The invention relates to an apparatus for activating and/or deactivating a security device, particularly an entry device for a motor vehicle, having a portable transmitter unit for wirelessly transmitting a coded information item which is received by a receiver apparatus and is compared with a prescribed coded information item, the receiver apparatus being capable of outputting an actuation signal to the security device if the two information items match, and the transmitter unit and the receiver apparatus being capable of being advanced in terms of the currently coded information items.

Abstract: The invention relates to an apparatus for activating and/or deactivating a security device, particularly an entry device for a motor vehicle, having a portable transmitter unit for wirelessly transmitting a coded information item which is received by a receiver apparatus and is compared with a prescribed coded information item, the receiver apparatus being capable of outputting an actuation signal to the security device if the two information items match, and the receiver apparatus being connected to a mechanical device for operating the security device. In an apparatus in which unauthorized deactivation of the security device is reliably prevented, the receiver apparatus is disabled for the reception and/or evaluation of the coded information items and/or for the output of the actuation signal to the security device after the security device has been mechanically activated, the block being lifted after the security device has been mechanically deactivated.

Abstract: A tube- or hose connector for the transport of a fluid has at least at one end a ring type nipple 2 with a cross hole 4, which serves to mount the connector at an aggregate for receiving a banjo bolt 12 having a head 13 and a threaded shank 14 as well as two gaskets 10, 11. It has a protecting cap 18 to hold together a premounted unit of ring type nipple 2, banjo bolt 12, and the two gaskets 10 and 11, and has an approximately U-shaped form with a clamp 19, at the one end of which a flank 20 overlaps the head 13 of the banjo bolt 12 and at the other end of which a protecting cover 20 for the threaded shank 15 of the banjo bolt 12 is provided. The protecting cap 18 has an extension 26 supporting itself at the threaded shank 15 of the banjo bolt 12, and the protecting cover 22 is borne pivotably at the clamp 19.

Abstract: The present invention pertains to a process and a system for controlling the movements of an axis on program-controlled machines, especially industrial robots, comprising a position control unit and/or a velocity control unit and/or a power control unit. The loads acting on the axis from the outside during the operation are measured by one or several sensors. The load signal is fed back regeneratively in the sense of an increase in the position control variance and sent to the summation point of the position and/or velocity control unit. To increase or decrease the mechanical flexibility of the axis, a controllable amplifying or attenuating device is provided. The sensors may have different designs, corresponding to the loads to be measured. They are preferably directly associated with the axes.
