  • Recognition of unauthorized access of a portable electronic apparatus
    Patent number: 12468791
    Abstract: To recognize an authorized user from an unauthorized user of a portable electronic apparatus, the portable electronic apparatus has a plurality of sensors and a user-recognition circuit. The sensors are each configured to generate a signal representative of a respective physical quantity associated with the use, by a user, of the portable electronic apparatus in an operating state.
    Type: Grant

  • Sigma-delta modulator for PWM applications with minimum dynamical control and dithering
    Patent number: 7830289
    Abstract: The circuit includes, upstream from a PWM quantizer, that is between the output of the sigma-delta modulator and the input of the PWM or PWM-like quantizer, a second or ancillary sigma-delta stage of any order and architecture, with the function of controlling the minimum dynamic of the sigma-delta modulator. This second sigma-delta stage is input with the output signal of the sigma-delta modulator summed to a signal corresponding to the difference between the input signal and the output signal of the second sigma-delta stage, delayed by a delay block.
