A network component () for an optical network () is described, including a coupling device () for optical coupling of the network component () to the optical network (), the coupling device () having a receiving module () and a transmitting module (); a first data processing device () which is unidirectionally connected to the receiving module (); a second data processing device () which is unidirectionally connected to the transmitting module (); the first data processing device () being unidirectionally connected to the second data processing device () for transmitting data to the second data processing device; a detection device () for detecting the network status; and a two-way switch () for switching of the input of the first data processing device () between the receiving module () and the output () of the second data processing device () as a function of the network status detected.

Network component for an optical network comprising an emergency operation function, especially for an optical network in ring topology

An electronic control arrangement including a plurality of inputs and outputs, whereby the outputs are controlled in relationship with the inputs according to a predetermined program. Additionally, the outputs are coupled to another input by way of a special-function line. When the control is switched on, the external wiring is called upon to supply information regarding the state of certain controllable circuit elements. Through this, the electronic control circuit automatically checks which one of the several stored programs is appropriate under the circumstance.

Electronic control arrangement for controlling a plurality of outputs in

An electropneumatic door control for vehicles is disclosed which consists of a pneumatic portion and an electronic portion. The electronic portion processes successive commands actuated by the vehicle operator to channel the signals to the pneumatic portion of the apparatus to activate alternate door openings and closings. Any blockage of the door movement is detected and signals processed to reverse the door closing or to halt the opening until the fault is corrected. The electronic portion also assures that the vehicle doors can only be opened after the vehicle has come to a stop, that when the vehicle doors are open the station or parking brake is held engaged, and that an audible warning signal sounds for a predetermined interval before the closing of the door.

Electropneumatic door control

An electro-pneumatic door control apparatus for use on public vehicles and including reversing mechanism for changing the direction of door movement, either automatically or operator-initiated, in the event of an obstruction in the door. The control apparatus further includes a flip-flop for recording the position (either open or closed) of the door at all times, a monitoring logic device for recognizing the position of the flip-flop and what type of monitoring function is permitted, a control logic device for picking up the door command and the signal from the monitoring logic device combing them and transmitting them to a valve solenoid control device for energizing respective solenoids of several valve devices by which the appropriate movement of the doors is effected.
