    摘要： An electronic card having an electronic control circuit, an elector-optical element configured as a normal operation indicator, and a power supply source. Electrical tracks connect the electronic control circuit with the electro-optical element and the power supply source, and affixing elements attach the electronic card to a substantially planer surface. The electrical tracks having embrittlement grooves which destroy the connections made by the electrical tracks upon removal of the electronic card from the substantially planer surface to which the electronic card is attached. The electronic card is suited for applications in the identification and automatic detection of objects and in particular, stolen vehicles.

    摘要： Cholesteric liquid crystals of the so-called reentrant mesogenic type obtained by mixing a substance such as a cholesterol ester having molecules of the "chiral" type with a liquid crystal of the so-called reentrant nematic type such as a substance corresponding to the general formula: ##STR1## where R is an alkyl or alkoxy or alkylcarbonate group with:R'=H or CH.sub.3and X is an organic radical such that CH=N, CH=CH, C.tbd.C or COO.The use of a liquid crystal in accordance with the invention serves to obtain a temperature-detecting device in which, in contrast to conventional cholesteric devices, the reflected light changes from blue to red when the temperature rises.
