  • Patent number: 10079577
    Abstract: A signal amplification circuit comprises a low pass filter circuit (100). The low pass filter circuit (100) comprises two input ends and two output ends and further comprises two capacitors (C1, C2) having opposite polarities respectively connected between two output ends. A buffer circuit (200) comprises two input ends, a first operational amplifier (A1) and a second operational amplifier (A2), two output ends and a plurality of switches. A switched capacitor integrated circuit (300) comprises two input ends, a third operational amplifier (A3), a plurality of capacitor modules, a plurality of chopper modulators and two output ends. A signal switch (S) is used to control the on and off states of voltage signal before amplification.

  • Patent number: 10056867
    Abstract: A sensor control circuit comprises a sensor (201), a filtering circuit (202), a buffering circuit (203), and an amplifying circuit (204). An output end of the sensor (201) is connected to an input end of the filtering circuit (202), an output end of the filtering circuit (202) is connected to an input end of the buffering circuit (203), and an output end of the buffering circuit (203) is connected to an input end of the amplifying circuit (204). Because the buffering circuit (203) is disposed between the filtering circuit (202) and the amplifying circuit (204), the sensor circuit has an advantage of full sampling. Further provided is an electronic apparatus using the sensor control circuit.

  • Publication number: 20160339284
    Abstract: A material drying and pyrolyzing method includes the following steps: sending material into rotary kettle; making use of microwave energy to heat material within rotary kettle to pyrolyze and decompose material in order to get decomposed gas and solid substance; condensing and recycling gas generated from the decomposing; recycling and disposing solid substance generated from the pyrolyzing. The method makes use of the microwave energy to rapidly heat material inside rotary kettle, and rotates rotary kettle at the same time to make material more uniformly heated, improve material pyrolyzing efficiency, which can greatly improve pyrolyzing and separating efficiency of material and effectively reduce energy consumption, with the improvement of safety performance of the equipment operation. It also avoids secondary pollution to environment caused by burning of heating energy, thus effectively improves economic and social benefits.
