The invention relates to a compressed air supply system (11, 21, 22, 23, 24, 25, 30, 41) for operating a pneumatic system (90, 901, 902), in particular a pneumatic suspension of a vehicle, comprising: a compressed air supply (1); a first pneumatic connection between the compressed air supply (1) and the pneumatic system (90, 901, 902), comprising an air desiccator (61), throttle means (62) and at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163); a second pneumatic connection which is pneumatically connected to the first pneumatic connection and to a ventilation connection (3) for connecting to the surroundings and which has at least one controllable ventilation valve (73, 73′, 73″, 73′″, 73IV, 173). According to the invention, said at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163) and the throttle means (62) are aligned in the first pneumatic connection in such a manner that the at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163) can be switched in an open state, into the flow through mode, and in the closed state, into a separation mode. In the closed state, the first pneumatic connection is completely closed in both directions and said at least one controllable separation valve (63, 63′, 63″, 63′″, 63IV, 163) can be switched, in the flow through mode, between a first control state, associated with a closed state, and a second control state which is associated with an open state.

The invention relates to an authentication method and an arrangement for performing such an authentication method and to a corresponding computer program and a corresponding computer-readable storage medium, said method particularly providing a simple and very cost-effective method for the authentication of persons upon the usage of services with the aid of mobile standard terminals without technical expansions such as RNID equipment or the like. For this purpose, it is provided that in the authentication method a terminal (103) is used, which is equipped with a loudspeaker (109′) and/or color display (109) and special software. In the authentication method, at least one authentication code is generated, first information is provided about the at least one authentication code to at least one user, and second information, which makes the terminal (103) suitable for outputting various tones and/or colors in a time sequence via the loudspeaker (109′) or the color display (109), respectively, is prepared from the first information. A sensor (102, 102′) for detecting the various tones and/or colors detects the time sequence of the various tones and/or colors, and an analysis unit, which is connected to the sensor (102, 102′) and has access to the at least one authentication code, decodes the time sequence of the various tones and/or colors and compares the result of the decoding to the at least one authentication code. The usage of services is released as a function of the comparison result.
摘要:
A compressor unit for an air suspension system of a motor vehicle, having a compressor, an air dryer and a compressed-air port for delivering compressed air from the compressor to the air suspension system and for introducing compressed air from the air suspension system into the air dryer. A ventilation line is provided from the air dryer to the environment of the compressor. The ventilation line has an upwardly convex bend when the compressor unit is in installed position.

A method is provided for coating a substrate with the aid of a magnetron cathode and two electrodes which are alternately impinged upon by a positive potential and a negative potential. Also disclosed is an assembly for coating a substrate, comprising a vacuum chamber, a magnetron cathode, two electrodes, and a voltage source. A negative potential is generated at a level that is no greater than the level of the cathode potential, thus preventing the electrode that is to be cleaned from being stripped to a greater extent than the same was coated in the previous half-wave. The magnetron cathode and the electrodes are connected to the voltage source via switching elements without being galvanically such that a negative and a positive voltage generated from the voltage source can be alternatively applied to the electrodes, the level of said voltage being no greater than the cathode voltage.

A gas exchange valve control for internal combustion engines includes an electromagnetic actuator equipped with gas springs. The gas exchange valve control has an armature, which drives the gas exchange valve and is arranged to oscillate between stroke-separated switching magnets against the gas springs. The armature serving as the separating piston between the gas springs is moveable without friction in a closed armature stroke space. A housing-like yoke, which encloses the armature stroke space, including the adjacent switching magnets, exhibits between the switching magnets a device which serves to shorten the respective magnetic circuit of the respective switching magnet.
