摘要： A method for orienting a parallax barrier screen on a display screen with picture elements x(i,j) in a grid comprising rows i and columns j for the purpose of producing a display screen for three-dimensional representation. This method includes the steps of: temporary application of a positioning marker, observation of the positioning marker by means of a camera, relative orientation of the display screen, removal of the positioning marker, positioning of the parallax barrier screen in front of the picture area of the display screen display of a test picture, which comprises various views, where k=1, . . . , n and n=6 or n=7, on the picture elements x(i,j) with rows i and columns j, observation of the displayed test picture through the parallax barrier screen by the camera, orientation of the parallax barrier screen in front of the display screen. The method according to the invention can be carried out quickly and is therefore suitable for industrial use for the manufacture of display screens for three-dimensional representation.

摘要： A method for determining a lambda air ratio using a gas sensor having a ceramic measuring element, an output voltage of the gas sensor changing abruptly if lambda is changed in the range around lambda=1 and the gas sensor having an initial inverse voltage which is dependent on the temperature of the gas sensor. A threshold value for the initial inverse voltage is established for a limit between a lambda value below and above 1 as a function of the temperature of the gas sensor. Also described is a device for implementing the method. The method and the device make it possible to operate gas sensors having a ceramic measuring element at an even lower temperature than according to the related art and thus reduce the period between the start of an internal combustion engine and the operational readiness of a lambda regulation. This makes it possible to reduce the fuel consumption as well as the emission of undesirable components of the exhaust gas.
