  • Touch-sensing device with a touch hold function and a corresponding method
    Patent number: 8749517
    Abstract: The invention relates to a touch-sensing device comprising an interaction surface with a touch location system for determining a touch position based on an acoustic signal. Gaskets, forming a means for acoustically isolating the interaction surface from the underground on which it is placed, are provided with an upper electrode and a lower electrode. The gaskets are elastically compressible and have dielectric properties, so that the two electrodes and the gasket form a capacitor with a capacitance that varies with the force applied to the interaction surface. In addition to the touch position determined by the acoustic signal, the touch-sensing device detects a touch duration based on capacitance variations, so that touch events can be classified according to their duration. The invention also relates to the corresponding method.

  • Method for determining the location of an impact on a surface of an object
    Patent number: 8670290
    Abstract: The invention relates to a method for determining the location of an impact on a surface of an object based on the analysis of an acoustic signal generated by the impact. This method further comprises a signal treatment step of weighting the acoustic signal to take into account spurious contributions in particular due to reflections at the border of the object.
