  • Patent number: 11520078
    Abstract: Determining a white plume control line of smoke after wet desulphurization includes: drawing a saturated air enthalpy humidity curve or equivalent; obtaining annual temperature and humidity change data of located cities or regions along with the time at the frequency of at least one datum every day; drawing the data obtained in the saturated air enthalpy humidity curve; and drawing a tangent line on the saturation curve by using each meteorological point in a chart, the right lower side of the tangent line is a de-pluming control region, the de-pluming effect superior to that at the feature meteorological point can be realized when the smoke enters the region after regulation, a region defined by the de-pluming control line and the saturation curve at a low-temperature side forms a de-pluming day number control region, and the point number falling within the region is the white plume generating day number.

  • Patent number: 11303998
    Abstract: Disclosed herein are techniques for determining a wearing position of a boomless headset. An earpiece of the boomless headset can include at least one local talker (LT) microphone and a reference microphone. The LT microphone(s) are disposed substantially in a first end of the earpiece closest to a mouth of a LT when the LT wears the earpiece. The reference microphone is disposed substantially in a second end of the earpiece, furthest from the mouth of the LT when the LT wears the earpiece. A signal strength measurement (SSM) for a local talker audio signal to the LT microphone(s) and a SSM for a signal to the reference microphone are obtained. Signal processing logic can determine whether the earpiece is worn at an incorrect ear based on whether a difference between the SSM for the LT microphone(s) and the SSM for the reference microphone is below a predetermined threshold.
