  • IMPEDANCE CARDIOGRAPHY DEVICE
    Publication number: 20230320606
    Abstract: The impedance cardiography device comprises an impedance measuring unit, connected to the human body to be measured, a differentiator, a comparator and a microcontroller integrated with an analog-to-digital converter, characterized by that the device further comprises two peak voltage detection units with different polarities (positive and negative), the strobing outputs of them being connected to the digital (binary) inputs of the microcontroller and the analog hold outputs to the inputs of the analog-to-digital converter.

  • Instantaneous power estimation in a continuous time digital signal processing system
    Patent number: 11496049
    Abstract: A continuous time digital signal processing (CT DSP) token includes a first signal indicating a change has occurred and a second signal indicating a direction of the change. An amplitude generation circuit operates to generate an amplitude value x in response to the token. A power estimation circuit processes the amplitude value x to generate a digital power signal in accordance with the formula: x2±2x+1.

  • Method for processing a digital signal in a digital delta-sigma modulator, and digital delta-sigma modulator therefor
    Patent number: 8594226
    Abstract: The digital delta-sigma modulator includes a signal input for receiving digital samples of N bits, and a digital filter connected to the signal input. The digital filter performs addition/subtraction and integration operations according to a redundant arithmetic coding for delivering digital filtered samples. A quantizer performs a nonexact quantization operation so as to deliver digital output samples of n bits, with n being less than N. The input of the quantizer is connected within the digital filter.
