  • Patent number: 9187103
    Abstract: A method for estimating the temperature (TB, est) of a wheel bearing of a wheelset of a rail vehicle by means of a calculation model (Tbearingestimator). The calculation model (Tbearing,estimator) estimates the temperature of the axle bearing, according to the speed (vtrain) and the ambient temperature (Tamb) of the rail vehicle as input variables of the calculation model (Tbearing estimator), and the temperature of a component of the wheelset, different from the axle bearing but directly or indirectly connected to the axle bearing in a heat-conducting manner, is measured as the measuring temperature (Tmeas) during operation. The temperature of the component different from the axle bearing is estimated by means of the calculation model (Tbearingestimator) as the estimated temperature (Tmeas,est).

  • Patent number: 9189885
    Abstract: A method and system for displaying a 2D representation of a 3D world on an image plane of a simulator. The image plane defines a fixed viewing region of the replica environment of the simulator and also corresponds to a view observed by an operator of the simulator. The method includes the steps of determining a head position of the operator of the replica environment and modifying a viewing volume of the 3D world based on the head position of the operator while keeping the image plane constant to form a modified viewing volume. The 2D representation based on the modified viewing volume is then generated and displayed on the image plane.

  • Patent number: 9022068
    Abstract: Compressor arrangement for generating compressed air using a motor-operator compressor unit, downstream of which at least one cooler unit is connected for cooling the generated compressed air, which enters the cooler unit via at least one inlet, flows there through a cooling structure, from a plurality of cooling passages connected in parallel and leaves the cooler unit via at least one outlet, wherein a permanently open bypass pipe is provided between the region of the inlet and the region of the outlet, the inner cross section of which bypass pipe is matched to the delivery capacity of the compressor unit and to the pressure difference between inlet and outlet such that the bypass pipe, at normal ambient temperatures, causes a higher flow resistance than the cooling structure, whereas, as freezing of the cooling structure progresses, the compressed air flows increasingly via the bypass pipe.
