  • Publication number: 20170259676
    Abstract: A charging cable for an electric or hybrid vehicle has a charging line with a number of conductors for conducting a charging current of at least 2 A. An outer sheath surrounds the conductors and a plug can be attached at an end side for connecting the charging line to a current source or to the vehicle. The charging cable has at least one display area on the outer sheath for displaying an operational state. A passive function element is integrated, which extends along the charging cable, which has a coupling point for light at the end side, and which is designed for guiding the light along the charging cable and for scattering the light in a radial direction. A charging system has such a charging cable for connecting a charging station with a vehicle.

  • Patent number: 6314888
    Abstract: A multi-stage gas generator comprises a housing with an outer wall and also inner walls, at least two combustion chambers filled with at least one propellant charge, one igniter each associated with a propellant charge for the independent activation of each propellant charge, and at least one thermal insulation arrangement between the propellant charges. The arrangement reduces a transport of thermal energy, generated on the ignition of a propellant charge, to the other non-ignited propellant charge to such a high extent that the non-ignited propellant charge remains below its autogenous ignition temperature. Instead of or additionally to the thermal arrangement a cooling arrangement may be provided.
