Abstract: The invention relates to a device and a method for isolating a fuel cell, which make it possible to safely work on the fuel cell during a servicing or repair operation.

Abstract: A hybrid crucible comprising a frame and a bottom plate. The crucible is characterized by the selection of material of these two components, which have been optimized in terms of thermal conductivity. The crucible is adapted to produce crystalline materials. Moreover, a method for producing crystalline material is disclosed.

Abstract: The presented invention relates to a method for monitoring an insulation state of a first high-voltage network and an insulation state of at least one further high-voltage network of a vehicle, wherein a single insulation monitor is connected to the first high-voltage network and to the at least one further high-voltage network, and wherein, by means of the insulation monitor, a first insulation measurement, initially, is carried out, in a periodically repeated sequence, on the first high-voltage network, and, then, a further insulation measurement is carried out in each case on the at least one further high-voltage network.

Abstract: A support component for a motor vehicle, in particular for a motor vehicle door is provided. The support component defines a support plane and defines two opposed side faces for the arrangement of functional components of a motor vehicle window lifter, wherein the support component includes at least one reinforcing structure for reinforcing the support component, wherein the support component forms at least two surface segments which on both side faces are arranged in the direction of extension along the support plane. The reinforcing structure is formed such that on the one side face it extends in a manner protruding with respect to both surface segments transversely to the support plane and on the other side face extends in a manner set back with respect to a surface segment of the two surface segments and protruding with respect to the other surface segment of the two surface segments.

Abstract: A method for security purposes is disclosed, in which a challenge signal is applied to a physical object and a response signal is received from the physical object. The response signal comprises a plurality of characteristic resonant optical mode or a characteristic of the response signal is determined based on a spatial resolution of at least two frequency components of the response signal that is affected by luminescence effect.

Abstract: Methods and systems consistent with the present invention facilitate inventory management by determining an order quantity and a safety stock based on the order quantity that provide a minimum total cost, while satisfying a service level over an entire demand period for a good or service. In one embodiment, a method includes determining a first order quantity, determining a search direction, and determining a second order quantity and a safety stock based on the first order quantity and the search direction, such that the second order quantity and the safety stock provide a minimum total cost.
