Latest Patents

Xiuzhen Dong holds a patent for an "Electrical impedance detecting device of portable electrical impedance imaging system and detecting method thereof." This device utilizes a theory of excitation and response signals to detect electrical impedance. The excitation signal is a square wave excitation current signal. The response signal on a target is transformed into a square wave signal with appropriate amplitudes through buffering, amplifying, RC filtering, and differential amplifying. This signal is then converted into a digital signal at a proper time by an analog-to-digital converter. The response signal is sampled once at high level and once at low level for each cycle by the ADC. The difference between the samples is taken as a detecting result for one cycle. An average value of the detecting results from multiple cycles is used as the final result. The final result illustrates the information of electrical impedance, as the excitation current signal remains constant.
