  • Patent number: 7356438
    Abstract: The present invention relates to a registering device for registering a location along a measuring line, at which location a temperature change takes place. In an advantageous way, according to one exemplary embodiment of the present invention, by means of the FMCW method a location on the measuring line is determined, at which location a temperature increase exceeds a predefined threshold value. The location is determined on the basis of a signal which is registered by the measuring line in response to a fed-in frequency modulated signal from evaluation electronics. Advantageously, in this way a simple and lightweight overheating warning system is provided, for example for hot-air supply pipes in aircraft.

  • Publication number: 20060033856
    Abstract: The invention relates to a display device comprising a first electrode (2) and a second electrode (6), and an optical layer (3) arranged between the electrodes (2, 6), which optical layer (3) emits light under the influence of an electric field applied between said electrodes (2, 6), and comprising a varistor layer (5) which is situated at least in the area of the pixels of the display device.

  • Publication number: 20050029947
    Abstract: The invention relates to a low-pressure gas discharge lamp which includes at least one discharge vessel and at least two capacitive coupling-in structures and operates at an operating frequency f. In order to achieve a better efficiency in combination with a small structural volume, a high luminous flux, a low operating voltage, a low electromagnetic emission, a high resistance against switching transients and a long service life for the low-pressure gas discharge lamp, it is proposed to form each capacitive coupling-in structure from at least one dielectric having a thickness d and a dielectric constant ?, each dielectric being subject to the condition d/(f.?)<10?8 cm.s. A substantially larger amount of light can thus be generated per lamp length (lumen/cm).
