Latest Patents
One of his latest patents is a Portable Ultrasonic Detector. This device features a moved distance instrument that includes an encoder for detecting movement and a counter for counting the output signal from the encoder. This setup allows for precise position information of an ultrasonic probe during inspections. The ultrasonic detector measures the moved distance of the probe and processes A-scope data to create detailed inner scope images, such as B-scope images. This innovation enables accurate detection of defect positions by displaying multiple defect images on the B-scope image.
Another significant patent is the Ultrasonic Signal Amplifier Circuit and System of Gain Control. This invention involves a variable gain amplifier circuit whose gain is controlled by applying a predetermined voltage signal during idle periods. The output is compared to an aimed value, and a gain control signal is produced to adjust the gain accordingly. This method allows for selective gain settings that enhance the performance of ultrasonic signal amplification.
