  • Sensitivity and selectivity of chemoresistor type gas sensors
    Patent number: 9753000
    Abstract: The sensitivity and/or selectivity of a chemoresistor type gas sensor is enhanced by measuring the response of the sensing material to a gas sample while the sensing material is subjected to illumination using specially-tailored pulses of ultraviolet radiation. For a given target gas to be detected there is an optimal duration of the UV pulses to achieve peak sensitivity of the sensing material.

  • Method and device for determining a touch gesture
    Patent number: 9678606
    Abstract: The invention relates to a device, in particular, a touch sensitive device, and more in particular, a single-touch sensitive device configured to recognize gestures, such as zoom, rotate, flick, using specific characteristics based on a single-touch localization system. The invention also relates to a method for recognizing/identifying gestures, such as zoom, rotate, flick, in a low-end device equipped with such as a single-touch sensitive device which is able to recognize one single point at a time.

  • Automatic gain control circuit
    Patent number: 8228121
    Abstract: An automatic gain control circuit including a variable gain amplifier (11) adapted to receive a received signal (R) and to output an amplified signal (A) to an analog to digital converter (20), and a gain controller (12) which is connected to said variable gain amplifier (11) for receiving said amplified signal (A) and for controlling a gain of said variable gain amplifier (11). The gain controller (12) is adapted to determine an occurrence of a threshold event each time the amplified signal (A) has reached a predetermined threshold, decrease the gain of the variable gain amplifier (11) at each occurrence of a threshold event, measure a delay since the last threshold event, increase the gain of the variable gain amplifier (11) if the delay is greater than a delay specified value and if the gain of the variable gain amplifier (11) is not maximum.
