A communication system which has a PROFINET IRT system with first communication devices for isochronous transmission. A special IRT bridge device is created, so that a traditional standard Ethernet communication device can also transmit real time-critical data over the PROFINET IRT system. The bridge device has a timer, which is synchronized in time with the timers of the first communication devices. In addition, a device for analysis of the transmission point in time of a real time-critical data telegram received by the communication device and a control unit are provided, such that the control unit controls the forwarding of the respective real time-critical data telegram to at least one second communication device as a function of the analyzed transmission point in time.

A folding seat for an aircraft has a backrest, a seat area and an armrest. The seat area is pivotable. When the seat area is pivoted, the armrest is pivotable downwards, the seat area and the armrest being coupled by at least one coupling element in the form of a bevel gear.

To save space it is often not possible to provide a comfortable seat beside a bed, for example for a second flightdeck crew. Normally, sitting on a bed is not comfortable for extended periods of time. The present invention states a backrest arrangement which can be changed from a foldaway position to a seating position. The backrest arrangement can be hinged to a wall. In foldaway position, the distance between a lower region of the backrest and the essentially vertical surface is shorter than in the seating position. In this way the backrest arrangement can for example be attached to a wall beside a bed; in the seating position the backrest arrangement provides a comfortable and safe seat.

An adapter is connected to a probe tube of an already installed PEG probe, cut off above the abdominal wall of the patient. The adapter comprises a retaining member, supported by the abdominal wall, structure for fixing the proximal end of the PEG probe and structure for connecting a delivery tube. The retaining member is embodied as a separate piece, comprising an opening for the passage of the PEG probe, while the structures for fixing the PEG probe and for connection of the delivery tube form an insert piece, which may be inserted in the retaining member with a tight fit. The adapter is simple to manipulate and of a construction with a limited height.

An adapter is connected to a probe tube of a PEG probe that is already in place, the probe tube being cut off above the abdominal wall of the patient. The adapter comprises an outer retaining element, which is supported on the abdominal wall, and comprises structure for fastening the proximal end of the PEG probe, and structure for connecting a delivery line to the flow channel. A shut-off element having a rotatable or displaceable closing body is provided for closing the PEG probe. The adapter is characterized by its universal use, simple handleability and small overall height.

Seating groups for passengers, for example in an aircraft cabin, are equipped with several seats having seat components supported on a support base on which the seat components, especially the seat sections are laterally slideable to make the seats wider when a passenger sits on a seat or narrower when a passenger is not sitting on a seat. The seat widening or narrowing is accomplished in several ways, for example, with the aid of a grooved shaft that operates as a spindle when turned by tilting a seat component, or by springs that vault upwardly when not loaded and spread when a passenger sits on a seat supported by the springs. The grooved shaft can be operated for example by an armrest or a seat section.

A luggage compartment system for a passenger cabin, especially for commercial airliners, is equipped with compartment units each formed by at least two compartments interconnected or coupled through a coupling, guide and drive mechanism (13) for moving the compartments of a unit from a closed upper position to an open lower position and vice versa. Each unit has a large compartment and a small compartment, the latter is intended for smaller luggage items, including fragile items, while the larger compartment is intended for large luggage including suitcases. In the closed position the two compartments of a unit are arranged next to each other in a direction extending crosswise to a longitudinal central vertical plane (10) through the aircraft cabin. The compartments have for their bottom contoured panels that are integrated into the ceiling of the cabin in the closed compartment position. The coupling, guide and drive mechanism (13) moves both compartments of a unit either up or down, whereby the compartments in their down position are located just above the passenger seats for loading and unloading with the smaller compartment being positioned above the larger compartment. Openings in the compartments face the central plane.

An aircraft cabin divider is so constructed that its installation can easily be handled by one person taking advantage of the force of gravity. For this purpose the divider has a frame with a first plug-in section that cooperates with a second socket section in the cabin structure, for example, the cabin floor or the cabin seating structure. The plug-in and socket sections cooperate so that an automatic lock-in is accomplished or so that a slight turn will provide the required interlocking. At least two couplings each including a plug-in section and a socket section are provided.

Comprehensive techniques identify data leaks in software applications using Asset Flow Analysis (AFA) to determine whether critical data leaves a system through an exit point such that the data is no longer protected by mechanisms of the system. A novel data extrusion mechanism makes use of a relevant subset of all the possible data paths detected by AFA using a knowledge base of critical business functions and critical database content. The system checks if any code performs read access to critical business data and subsequently transfers this data beyond the control limits of the target system. The knowledge base can be extended by configuring which database content is to be regarded as critical in any given organization. The approach is particularly valuable in protecting systems that manipulate, distribute, or store sensitive information associated with financial, business, or personal data, including SAP® ABAP™ software applications.
