Diagnostic and inspection by sound

Sound has been used for diagnostic of health, inspection of building defect, detection of piping water leak, and so on. SonicAnalyzer is a Windows application to analyze sound at frequencies between 10 Hz and 20 kHz. Its visualization, analysis, and customizable database will strongly support these diagnostic and inspection.
USB audio interface（16bit 48kHz) and state-of-art high-sensitive and low-noise microphone (patent pending) are supplied with SonicAnalyzer.



Visualization of Sound

Sound visualization is supported by usual spectrogram, and continuous scalogram which has higher resolution.


Customizable Database

Database can be designed freely.



Playback-supported Audio Player

Sound is continuously recorded, and the past sound can be heard and plotted.



Custom-made Audio Filter

Sound can be heard through audio filter. Custom-made filter can be designed by multiple cascade of 9 filter elements, low-pass filter, high-pass filter, and so on. The filter effect can be plotted and confirmed by music and white noise.



Sound Analysis

Visualized sound can be compared by a reference sound, which can be old own data or around 100 typical cases. The compared difference is shown from the reference adjusted by the shift and stretch of time.

Biosensor Integrated Circuit

In view of the growing concerns about such issues as food security, health care, evidence-based care, infectious disease, and tailor-made medicine, a portable gene-based point-of-care testing (POCT) system is needed. For a system that anyone can operate anywhere and obtain immediate results, a new biosensor chip must be developed. Electrical detection using complementary metal-oxide semiconductor (CMOS) integrated circuits has great potential since it eliminates the labeling process, achieves high accuracy and real-time detection, and offers the important advantages of low-cost, compact equipment.



Biosensors are devices that combine a biological component (a recognition part) and a physicochemical detector component (a transducer). The recognition part can be constructed using enzymes, antibodies, cells, tissues, nucleic acids, and peptide nucleic acids. The transducer consists of potentiometric, amperometric, and impedimetric sensor circuits. A few biological molecules can be detected in a micrometer-scale region. Sample with milli liter is divided into pico liters, and detected in massively-parallel. We have developed such biomedical chips with high integration of micrometer-scale sensors. We have also developed stand-alone equipment. BCT-II is a general purpose equipment, suitable to research and development. BCT-III is a user friendly equipment specialized to specific application. BCT-II and BCT-III use same chips, so it is east to move from research and development to products.
