  • Area-efficiency delta modulator for quantizing an analog signal
    Patent number: 8842029
    Abstract: The invention comprises sample-and-hold circuit and digital-to-analog converter into a differentially operational unit. In analog-to-digital conversion unit, on the premise of fixed or non-fixed quantization error, analog-to-digital converter dynamically adjusts number of bits solved or size of quantized step according to the magnitude of differential voltage between sampled input signal and previously quantized input signal, thus this invention can reduce the non-necessary power consumption from redundant code and overload of input signal. Differentially operational unit and analog-to-digital unit share the same capacitor array which has binary-weighted arrangement to reduce circuit complexity and area.

  • Extraction process with novel solvent regeneration methods
    Patent number: 8663461
    Abstract: Solvent regeneration to recover a polar hydrocarbon (HC) selective solvent substantially free of hydrocarbons (HCs) and other impurities from a solvent-rich stream containing selective solvent, heavy HCs, and polymeric materials (PMs) generated from reactions among thermally decomposed or oxidized solvent, heavy HCs, and additives is provided. A combination of displacement agent and associated co-displacement agent squeezes out the heavy HCs and PMs from the extractive solvent within a solvent clean-up zone. Simultaneously, a filter equipped with a magnetic field is positioned in a lean solvent circulation line to remove paramagnetic contaminants. The presence of the co-displacement agent significantly enhances the capability of the displacement agent in removing the heavy HCs and PMs from the extractive solvent.
