  • Patent number: 10061976
    Abstract: The disclosure relates to a device for capturing person-specific data of a person, wherein the person-specific data comprises a facial image of the person, wherein the device has a camera for recording the facial image of the person, a lighting apparatus, and a semi-transparent mirror, wherein the semi-transparent mirror is arranged between the person and the camera, wherein the semi-transparent mirror is oriented such that, on the side of the semi-transparent mirror facing towards the person, the optical path of light incident on the semi-transparent mirror is parallel to the optical path of the portion of this light reflected back by the semi-transparent mirror, wherein the lighting apparatus is used to illuminate the person from the front, wherein the device also has a control unit for capturing an image, by generating light by means of the lighting apparatus in order to illuminate the face of the person and, during the illumination, capturing a first image of the face of the person by means of the camera,

  • Patent number: 8646324
    Abstract: A method for dynamically diagnosing an exhaust gas probe. A target/actual comparison is performed between a calculated O2 signal and an O2 signal measured with the exhaust gas probe, for a step load transition. A device for dynamically diagnosing an exhaust gas probe disposed in an exhaust duct of an internal combustion engine. An output signal is fed to an engine controller connected to additional input signals providing information about intake air mass and fuel metering. The engine controller comprises devices for determining a calculated O2 signal from the information about the input air mass and the fuel metering and devices for filtering and/or gradient forming and/or integrating the calculated O2 signal and an O2 signal measured by the exhaust probe. A target/actual comparison between the calculated O2 signal and the measured O2 signal, can be performed for a step load transition.
