Latest Patents

Shimura's latest patents focus on an apparatus for measuring the characteristics of an ultrasonic wave medium. This invention determines the distribution of the attenuation slope coefficient in real-time using the center frequency shift. In one embodiment, the phase difference between a received signal and a reference signal is calculated using EXCLUSIVE OR gates or an inverse trigonometric relation stored in a ROM. The phase difference is then input to a differentiator, which outputs the center frequency shift of the received signal in real-time. This center frequency shift is subsequently processed by another differentiator to yield the attenuation slope coefficient. The design allows for the attenuation slope coefficient to be determined using simple hardware, eliminating the need for complex calculations such as power spectrum analysis and the first moment.
