Abstract: The electro-optical display device includes at least one electro-optical assembly, in particular an electro-optical cell (4), electrically connected to a supply unit (12) by means of elongated flexible supports (6, 8). Metallized tracks are arranged on the flexible supports which support integrated circuits (16). The flexible supports are assembled to the electro-optical cell and have loose intermediate portions formed by folds (42) which are free and thus allow positioning of each segment (44) situated between two consecutive folds with respect to the electro-optical cell which is independent of the positioning of the other segments.

Abstract: The present invention concerns a measuring device, notably for measuring the level of glucose in blood, intended to be used with a removable sensor comprising at least one active zone. In particular, the invention concerns the electrical connection between the measuring device and the removable sensor. Each electrical contact surface of the removable sensor is connected to two electrical contact organs to enable the condition of the electrical contacts between these electrical contact organs and the corresponding contact surfaces to be checked before a measurement is carried out.

Abstract: The arrangement of the invention enables control of a light emitting element comprising at least one discharge tube. Firing of the tube is effected by a generator which provides voltage pulses at predetermined periodic intervals (T.sub.r). The luminous intensity of the tube is controlled by a D.C. source which enables application of a discharge maintenance current to the tube, the duration of application (T.sub.c) of which depends on an instruction signal. A circuit is provided to assure synchronism between the application of the voltage pulse and the maintenance current. The arrangement may be applied in matrix displays.

Abstract: The invention concerns sports timing systems and in particular connections etween a central processor which determines the performances of the competitors and the peripheral devices which provide such processor with the necessary information such as starting and arrival times, intermediate times and as well as any other information necessary for the identification of the device concerned or of the competitor.

Abstract: A method and apparatus for detection whether an input signal is periodic or aperiodic, wherein reference pulses at a constant frequency are added during a first interval determined by a number of cycles of the input signal and reference pulses at the same frequency are substracted during a second interval determined by an equal number of cycles of the input signal. If the input signal is periodic, the counting result is zero or nearly zero since the counting intervals have been of equal duration. If the input signal is aperiodic, the counting result differs from zero because the counting intervals have not been of equal duration.
