  • Cooling Device and Method for Cooling a Component Produced in a Lost Foam Casting Method
    Publication number: 20150165520
    Abstract: A cooling device is provided for cooling a component produced in a lost foam casting method by way of an EPS model. The cooling device has at least one cooling element which can be disposed flat on at least one region of the EPS model. The at least one cooling element can be fixed in a materially bonded and/or non-positive manner to the at least one region of the EPS model. A method for cooling the component produced in the lost foam casting method by way of the EPS model using the cooling element is provided.

  • Device and method for activating passenger protection means
    Patent number: 8249779
    Abstract: In a method and a device for activating passenger protection device(s), the passenger protection device(s) are activated as a function of a first signal of an acceleration sensor system and a second signal of a structure-borne noise sensor system. The activation is decided as a function of a position of a vector composed of at least two features of the first signal in relation to a characteristic curve, the characteristic curve being modified as a function of the second signal.

  • METHOD AND CONTROL UNIT FOR TRIGGERING OCCUPANT PROTECTION MEANS FOR A VEHICLE
    Publication number: 20100256873
    Abstract: A method and a control unit for triggering occupant protection means as a function of a structure-borne noise signal are proposed. The occupant protection means are triggered as a function of the crash signal and the structure-borne noise signal, the structure-borne noise signal being evaluated beforehand as a function of at least one friction process which takes place in the vehicle structure.
