  • Patent number: 7919935
    Abstract: An electroluminescent (EL) element is connected to the power supply and is intermittently operated as a lighting device and as a brightness sensor. For this purpose, the processing unit induces the controlled AC voltage source to reduce the voltage for a short period. The current intensity is measured by current measuring devices and the corresponding measuring signal is digitized using the analog/digital converter (A/D). A processing unit uses the signal and the effective voltage to determine, by means of empirical calibration data stored in the memory or by using a calibration function, the brightness, i.e. the luminance of the light that is incident on the EL element. The processing unit associates, using desired values stored in the memory, the detected brightness with an operating voltage level which ensures the desired emission brightness of the EL element when operated as a lighting device.

  • Patent number: 7914329
    Abstract: A card connector comprises a plurality of contacts, a frame, a shell and a locator. Each of the plurality of contacts comprises a first portion extending in a first direction and a second portion extending in a second direction perpendicular to the first direction. Each contact has substantially an L-like shape. The frame has a front end portion and a rear end portion. The rear end portion holds, in part, the first portions of the contacts. The first portions extend into a space defined by the frame toward the front end portion in the first direction. The second portions extend away from the frame in the second direction. The shell is attached to the frame. The shell shields, in part, the second portions of the contacts. The locator is supported by the shell. The locator is distinct from the shell. The locator holds, in part, the second portions of the contacts so that the second portions penetrate the locator.

  • Patent number: 7915839
    Abstract: The invention relates to a method for compensating the ageing-related loss of luminosity of an electroluminescence element, according to which the cumulative electrical energy supply, i.e. the integral of the supplied electrical power over the period of operation, is used as a criteria for the compensating regulation of the operating voltage. The processing unit continuously integrates the supplied electrical power over time. The relation between the operating voltage and the emission luminosity of the electroluminescence element is stored in the memory for different cumulative electrical energy supplies. The stored data can be defined by means of a model or estimated on the basis of empirical values. The relation can be stored in the form of values stored in a tabular manner or as an analytical function in the memory.
