Abstract: In order to optimize the failure safety of electrical and electronic components located in an engine compartment of a rail vehicle, which additionally comprises at least one driver's cab, the rail vehicle is operated with an air conditioning system, which is provided to generate overpressure in the engine compartment and to control the climate of the at least one driver's cab. The air conditioning system includes a first air guidance system to introduce fresh air into the at least one driver's cab and a second air guidance system to transmit at least one part of the fresh air introduced into the at least one driver's cab into the engine compartment.

Abstract: Described herein are systems, devices, and methods for discovering and assigning wireless speakers to one or more devices capable of providing audio content. In some embodiments, the speakers may receive one or more channels of multi-channel audio content. In some embodiments, one or more wireless speakers are discovered, a prompt identifying at least one speaker location is provided at an output device, a list of wireless speakers is provided to the output device, wherein the list of wireless speakers corresponds to the discovered one or more wireless speakers, a selection of a wireless speaker from the list of wireless speakers is received; and the selected wireless speaker is associated to the at least one speaker location.

Abstract: A method and corresponding apparatus is provided for determining the location of a configuration server being connected to a totally symmetric network infrastructure that does not exhibit any symmetry breakers on network level. The configuration server reaches a decision to determine its network-wide unique configuration in order to be able to serve controllers. This decision depends on the plug position of the configuration server under consideration and the assumption of plugging rules governing a “good” network infrastructure. The controllers periodically send network packets that will be marked if they traverse specific connection elements in the network. The origin and the path of a network packet can be determined. The decision making is based on a majority function based on the packets received by the configuration server. If a decision cannot be made, then errors in the cabling structure can be detected.
