摘要:
Systems and methods are provided for operating a network arrangement including multiple network devices that are coupled to each other in a ring structure. Each network device includes a control device and a switch device with at least two ports for coupling to a communication path. During operation, at least two VLANs are simultaneously provided in the ring structure, and the sending of a data packet from the control device of a selected network device is performed via a port of the switch device in one of the two VLANs. In order to achieve this, the other port of the switch device of the selected network device is deactivated for the one VLAN. By using two VLANs, a redundant and reliable data transmission may be achieved. A destabilization of the VLANs in the network ring is prevented by the targeted deactivation of specific ports of the sending network device.

A device for supplying energy to hydraulically or pneumatically actuated active implants. The device can take the form of pumping systems, metering systems, and/or occlusion systems. The device comprises a receiving coil for generating an electric voltage due to a changing magnetic flux that is generated by an extracorporeal transmitting coil. The receiving coil is designed such that said coil can be implanted into subcutaneous tissue. Furthermore, an electric line is provided for transmitting the electric current that is generated by the receiving coil from the receiving coil to the active implant. The device further comprises a compensation container for temporarily receiving a transmitter fluid, by means of which the active implant is activated. The compensating container is mounted on the receiving coil and/or on the electric line such that the compensating container together with the receiving coil and/or the electric line can be implanted into a common tissue or muscle pocket in the body of a patient.

The invention relates to a method for operating a communication network (101), in particular an Ethernet network. Network devices (1) which are coupled to the network comprise a switch device (4), a first and a second control device (2, 3) which are coupled to the switch device (4), and the switch device (4) comprises for the first and the second control device (2, 3) a respective input port (10, 14) and emitter port (9, 13) for sending and receiving data via the communication network (6). Ring-shaped communication paths for data are provided so that redundant data can be transmitted in different directions and checked for consistency. An improved protection against failure and error analysis in the event of transmission errors are ensured by the ring-shaped structure using bidirectional communication paths. The invention further relates to a network arrangement (101) comprising several corresponding network devices (100, 200, 300) which operate according to the method.

A nozzle bar (10) comprising a carrier element (12) provided with several slit-shaped fluid channels (20), each associated with a foil (13) having a plurality of nozzle openings (15). In the position of use, the foil (13) is arranged over an input orifice (23) of the associate fluid channel (20) so that its nozzle openings (15) are located inside the contour of its associated fluid entry opening (19). In this position of use, each foil (13) is fastened to a plane attachment surface of the carrier element (12). The attachment surface may be the bottom (26) of a groove-like recess (25) in the carrier element (12). A separate recess (25) is provided for each foil (13). The carrier element (12) can be used for numerous different types of foils. The distance of the nozzle openings (15) of the foil (13), or the size or the form of the nozzle openings (15) may vary among various foil types, without requiring modifications on the carrier element (12).

With a method for synchronization in a communication system that includes a central participant and at least one further participant, at least one of the further participants being synchronized with the central participant, and, to this end, a telegram with synchronization information being transmitted by the central participant to the at least one further participant, particularly efficient synchronization of the at least one participant with the central participant results due to the fact that the telegram is a data telegram.
摘要:
A heart support device for pulsatile delivery of blood comprising a first and a second ventricle and a pump. Both ventricles comprises a fluid chamber and a blood-conveying chamber, wherein each fluid chamber can be filled with a fluid or emptied by way of the pump in such a way that an expansion or contraction of the fluid chamber occurs. In an expansion of the fluid chamber of a ventricle, a compression of the blood-conveying chamber of the same ventricle takes place, wherein a rigid pressure plate is disposed between a fluid chamber and the respective blood-conveying chamber, said pressure plate being able to move in the direction of the respective blood-conveying chamber.
摘要:
In a method for reading and/or storing injector-specific data for controlling an injection system of an internal combustion engine, an injector is charged by a control unit according to a predeterminable voltage curve and, depending on the case, is discharged directly by the control unit or by a power element located on a data storage medium and the voltage is measured by the control unit and by the data storage medium. Dependent upon a predeterminable voltage curve, a predeterminable amount of data is stored or read on a memory unit of the data storage medium.

The latch needle in accordance with the invention comprises a needle tongue with an integrated spring that is configured as the functional element on the needle tongue. No separate tongue spring, whatsoever, need be accommodated in the saw slot. This novel needle concept is robust and suitable for high operating speeds.
摘要:
With a method for synchronization in a redundant communication system that includes a central participant and at least one further participant, at least one of the further participants being synchronized with the central participant, and, to this end, at least two telegrams containing synchronization information being transmitted by the central participant to the at least one further participant, if there is a transmission error involving a telegram containing synchronization information, it is still possible to carry out synchronization due to the fact that, based on the synchronization information contained in the at least two telegrams, resultant synchronization information is obtained and is used to synchronize the further participants with the central participant.
