We developed a wearable ultrasound monitoring device to monitor the collapse of tongue roots of sleep respiratory patients throughout the night,completed clinical trials in the sleep center. The experimental results show that this device can effectively monitor OSA. The tongue structure changes at the timeintegrates ultrasound information into the commercial PSG system. It is expected

"1.Background: The deterioration of lithium batteries leads to safetycost issues. Ultrasonic detection has the advantages of cost, size,immediacy. 2.Detection: Under the control environment, the ultrasonic signal is actuated on each part of the battery,the reflectedtransmitted wave is collected. 3.Analysis: It has methods such as spectrum, image,DL to evaluate the SoH, the distribution of degradation types,the location of faulty cells in the battery module. 4.Theory: Use the acoustic properties of the battery with software simulation to verify the measured data."
