摘要： Various embodiments of a low-power-consumption analog-to-digital converter (“ADC”) for a touchscreen or touch panel in a capacitive sensing system are disclosed. The ADC is configured to operate in a first mode or a second mode. The first mode is characterized by a first resolution having a first number of ADC bits and a first level of power consumption associated therewith. The second mode is characterized by a second resolution having a second number of bits and a second level of power consumption associated therewith. The ADC operates under control of the controller and is configured such that the first number of bits is greater than the second number of bits and the first power level is greater than the second power level. The controller causes the ADC to switch from operating in the first mode to operating in the second mode when low radio frequency (RF) noise conditions are detected by sense circuitry, the ADC and/or the controller.

摘要： A method for calibrating fracture networks. The method includes estimating an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus, and fracture height; determining microseismic event envelope and base intensity data using a three-dimensional geomodel including microseismic event data; and determining hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data. The method further includes calibrating the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity, determining a proppant transportation and distribution scenario, and generating a dual porosity reservoir model based on the calibrated HFT fracture intensity and the proppant transportation and distribution scenario.
