  • Patent number: 10119839
    Abstract: A sensor circuit and method. The circuit includes a first subcircuit that includes a first sense capacitor, a first integration capacitor, and a first clock input for receiving a first digital clock signal for initiating discharge of the first integration capacitor at time T. The circuit includes a second subcircuit that includes a second sense capacitor, a second integration capacitor, and a second clock input for receiving a second digital clock signal for initiating discharge of the second integration capacitor at time T+Td. A rate of discharge of the first and second integration capacitors is at least partly determined by a capacitance of the first and second sense capacitor, respectively. At time Teval, after initiation of discharge of the first and second sense capacitors, the extent to which the first and second integration capacitors have discharged is compared. A digital signal indicating the result of the comparison is outputted.

  • Patent number: 9984257
    Abstract: A secure electronic apparatus and a method for determining that a secure electronic apparatus has been tampered with. The apparatus includes a memory and a plurality of sensors which each to receive an input signal and output a digital signal determined by the input signal and by a physical quantity sensed by the sensor (e.g. capacitance). A measurement routine includes applying a plurality of input signal values to the sensors and, for each input signal value, using the digital output signals of each sensor to determine a combined output result. The combined output results of the measurement routine are compared with a set of combined output results stored in the memory. A detected a difference between the combined output results of the measurement routine and the set of combined output results stored in the memory can be used to determine that the secure electronic apparatus has been tampered with.

  • Publication number: 20100221846
    Abstract: In an example embodiment, there is a sensor for detecting particles. The sensor comprises an electrode, a sensor active region covering the electrode and the sensor active region is sensitive-for the particles. A first switch element is operable to bring the electrode to a first electric potential when the first switch element is closed, and a second switch element is operable to bring the electrode to a second electric potential when the second switch element is closed. A detector is adapted to detect the particles based on a change of the electric properties of the sensor in an operation mode in which the electrode is brought to the first electric potential and an operation mode in which the electrode is brought to the second electric potential.
