  • Patent number: 7378762
    Abstract: The invention concerns an electrical circuit for limiting the switching-on current through a load during a switching-on process, comprising an electrical component which is connected in series to the load. To ensure current limitation which is independent of the load and of the value of the supply voltage, and simultaneously to avoid switching current peaks and minimize dissipated heat, the current-limiting component is in the form of an active component which has an internal resistance, and which is controlled by a timing element in such a way that the internal resistance of the component is reduced during a switching-on process.

  • Patent number: 7342243
    Abstract: A device and method for reading out information stored in a storage layer using a receiving device for receiving emission radiation that has been emitted from the storage layer. In this connection the storage layer is supported on a support surface that is defined by an x-y plane and a relative movement is generated between the receiving device and the storage layer in the x direction. The receiving device or the storage layer is guided during the generation of the relative movement by a guide system, on a guide surface that is independent of the storage layer. When guiding the receiving device, the level of the guide surface in a z direction coincides with the level of the support surface in the z direction.
