  • Publication number: 20200349821
    Abstract: An integrated circuit chip (2), an antenna (3) and a tamper loop (4), and in addition to this, a light emitting diode (LED) (20), configured to be activated, i.e. supplied with current, upon a signal received by the antenna (3). The LED (20) is integrated in the device in such a way that when the LED is activated in the above-described way, the LED lights up so as to become visible by the naked eye, on the condition that the tamper loop (4) is in a predefined state, either open or closed. The LED (20) is coupled between the same terminals (8,9) of the integrated circuit chip (2) as the tamper loop (4).

  • Patent number: 9448266
    Abstract: The method is for measuring a physical parameter via an electronic circuit connected to a two differential capacitor sensor having two fixed electrodes and a common moving electrode. The circuit supplies first and second digital measuring signals. Each measuring cycle consists on biasing fixed electrodes by a first biasing and a second biasing reverse of the first biasing, alternated with biasing the electrodes by the measuring voltage based on first and second digital signals. Each conversion starts by a small step value added to or subtracted from each digital signal in each cycle. If the successive identical amplifier output states counted or counted down by a counter is higher than a threshold, a large step value is added to or subtracted from the digital signals in each cycle. Re-adaptation to the small step value occurs when a sign change is detected in the counter, until the conversion end.

  • Patent number: 9047527
    Abstract: Method for reading a barcode by means of an optical reader arranged to capture at a determined sampling frequency a series of partial images of the barcode by a sensor having at least one line of pixels. According to the invention it is provided to determine in each partial image a logical value as a function of the light intensity received by a central pixel of the line of pixels and a corresponding bar width when this bar is completely incorporated into the partial image in question. By only setting a maximum speed for the speed of movement of the barcode and dimensioning the line of pixels to ensure that each bar of this barcode is completely incorporated into a partial image at least once, the sequence of bits defined by the barcode is determined by means of an algorithm ignoring the duplications detected in consecutive partial images.
