Patent number: 9689659Abstract: The disclosure relates to a method of detecting an object using a detection signal supplied by a proximity sensor. The method comprises the steps of generating a reference signal by filtering the value of the detection signal, defining a first detection threshold, and going from an object non-detecting state to an object detecting state when the value of the detection signal becomes greater than the first detection threshold. When the value of the detection signal becomes greater than the first detection threshold, the value of the reference signal is readjusted in a manner such that the value of the detection signal again becomes less than or respectively greater than, the first detection threshold.Type: GrantFiled: October 8, 2014Date of Patent: June 27, 2017Assignee: STMicroelectronics (Rousset) SASInventors: Maxime Teissier, Cyril Troise

Patent number: 6140869Abstract: A device for demodulating a binary signal having a predetermined carrier frequency and phase-modulated by encoded pulses. The device includes a phase-locked loop circuit having a phase comparator followed by a low-pass filter and a voltage-controlled oscillator, which is voltage-controlled by the output of the filter. The voltage-controlled oscillator outputs a binary signal that is synchronous with the modulated signal and at a frequency N times the carrier frequency. The phase-locked loop circuit also includes a divider that divides by N the output signal of the oscillator and supplies the divided signal to one input of the phase comparator. Thus, a binary signal synchronous with the modulated signal and having a frequency equal to the carrier frequency is supplied to one input of the phase comparator. The other input of the phase comparator receives the modulated signal.Type: GrantFiled: January 20, 1999Date of Patent: October 31, 2000Assignee: STMicroelectronics S.A.Inventor: Cyril Troise
