摘要:
A method and apparatus for data transmission between an electromedical implant having a first transmitter/receiver unit, such as a cardiological implant, and an associated external apparatus having a second transmitter/receiver unit. Data transmission begins with a triggering signal which is sent by the first transmitter/receiver unit in normal operation in predeterminable first intervals. Reception readiness of the first transmitter/receiver unit is maintained after emission of the triggering signal for a second time interval which is shorter than the first time interval.

摘要:
A process for producing a purified hydrogen product without a pre-reformer or pre-reforming catalyst in a fired, tubular reformer where the feed stream having a carbon (i.e., C2+) molar composition greater than or equal to five percent and is mixed with a steam stream to yield a reformer feed stream with a steam-to-carbon ratio less than or equal to three. The reformer tubes contain a nickel-based catalyst without alkali promotion.
摘要:
A method for operating a steam reforming plant wherein a hydrocarbon-rich feed is reacted with steam to form synthesis gas. The plant includes a steam reforming reactor and processing units to obtain a hydrogen-rich fraction after separation of carbon dioxide and carbon monoxide. The plant also includes a pressure-swing adsorption plant to separate the hydrogen-rich fraction into product and residual gas. A recycle compressor is included and allows the plant to operate is two different modes. In the first mode, carbon dioxide separated from the synthesis gas is compressed and added to the hydrocarbon-rich feed. In the second mode, the recycle compressor is used to recycle residual gas from the pressure-swing adsorption plant to the hydrogen-rich fraction upstream of the pressure-swing adsorption plant.
摘要:
A battery system comprises at least two modules which include a plurality of battery cells, with each module being associated with a cell voltage detection unit which is connected to a central controller via a common communication bus. Each module additionally includes a module voltage detection unit which is connected to the central controller and is configured to separately detect the voltage of the associated module.

The invention relates to a craft comprising an energy storage system of the RFCS (regenerative fuel cell system) type and a system for pressurizing the propellants used for propulsion. The craft also comprises a plurality of means (31 to 38) for coupling the tanks of the fuel cell to the propellant-pressurizing tanks of the propulsion system of the craft when the tanks of the propellant-pressurizing system are no longer used.The invention also relates to the method of coupling the tanks of the propellant-pressurizing means to the energy storage system.The invention applies particularly to telecommunication satellites and more generally to spacecraft.
摘要:
A method for operating an internal combustion engine includes: providing a desired power specification for triggering the drive unit; providing a specification of operating point-dependent power ranges for the supplied desired power specification, in which steady-state operation of the drive unit is permissible, a power range that is not permissible in the steady state being defined between the operating point-dependent power ranges; when a change in the desired power specification for the drive unit in a transitional operating mode necessitates traversing the power range that is not permissible in the steady state, triggering the drive unit on the basis of a specification of a guided desired power, the guided desired power specification being determined by guiding the desired power specification.
摘要:
A method of making a wireless communication connection between a patient device and an electromedical implant as communication partners is disclosed, wherein a transmitting unit of the patient device is continually switched on and off, so that the transmitting unit is alternately in an activity phase and an activity pause and during its activity pause at least once sends a recognition signal and wherein a receiving unit of the electromedical implant is continually switched on and off so that the receiving unit is alternately in an activity phase and an activity pause and during its activity phase checks whether the transmitting unit is just then in its activity phase and sends a recognition signal, wherein switching on and off of the receiving unit is so effected that an activity phase and an activity pause of the receiving unit together give an overall duration which differs from the overall duration of an activity phase and an activity pause of the transmitting unit so that within a foreseeable period of time the activity phases of the transmitting unit and the receiving unit overlap and a wireless communication connection between the two communication partners occurs.
摘要:
A mounting plate for electronic components, including cooling conduits that are integrated into a plate body and that are traversed by a coolant, and a fixing device for mounting the electronic components being located on the plate body. The fixing device includes at least one retaining piece and a first recessed groove or channel that extends in a linear manner in the direction of extension of the mounting plate. A retaining piece, which includes a fixing thread, for securing the component can be inserted into the groove or channel.
