Latest Patents
One of his latest patents is the "Ultrasonic Continuous Wave Blood Flowmeter Using Doppler Effect Analysis." This innovative device includes a filter with a cut-off frequency that can be manually adjusted based on a selected zero shift value. The flowmeter features a transducing device that consists of a transmission element and a reception element. The transmission element converts an electric signal into an ultrasonic signal, which is then used to irradiate a living body. The reception element transduces the reflected ultrasonic signal back into an electric signal. A detecting circuit is connected to the transducing device to orthogonally detect the electric reception signal and output a Doppler detection signal. Additionally, a filter circuit is employed to cut high-frequency components of the Doppler detection signal, resulting in an analog signal. This signal is then converted into a digital format for further analysis using a Fourier transform method.
Another significant patent is the "Ultrasonic Pulse Doppler Blood Flow Meter." This device incorporates an amplitude equalizing circuit that is placed between the high-pass filter and the Doppler analyzer. This circuit not only optimizes the input dynamic range of the Doppler analyzer but also automatically adjusts the cut-off frequency of the high-pass filter according to the input signal. As a result, this blood flow meter requires minimal manual adjustments, making it user-friendly and efficient.
