Abstract: A bladder urine volume monitoring system and a bladder urine volume monitoring method are provided. The bladder urine volume monitoring system includes at least one ultrasound patch, at least one muscle stimulation patch, and a control circuit. The ultrasound patch is configured to be attached to a surface of an organism to detect a urine volume in a bladder. The muscle stimulation patch is configured to be attached to the surface of the organism to stimulate a muscle of the bladder. The control circuit is coupled to the ultrasound patch and the muscle stimulation patch. The control circuit drives the ultrasound patch to detect the urine volume in the bladder in a first period. The control circuit drives the muscle stimulation patch to stimulate the muscle of the bladder in a second period.

Abstract: An ultrasonic system and an ultrasonic method with adaptive overflow and gain control are provided. The present disclosure uses two-stage gain controls to improve the signal-to-noise ratio (SNR) and to achieve the correct analysis of results. The first stage adopts an analog gain, and monitors whether the signal may overflow or its signal strength is too weak, and adjusts the gain value as large as possible, without causing overflow in order to improve the SNR. The second stage adopts a digital gain. In the second stage, all the amplified gain-containing data adjusted in the first stage are received, and an amplified gain-containing data segment is sequentially retrieved in chronological order, and the amplified gain-containing data segment is converted into a same-gain data segment having the same gain. Finally, the same-gain data segment is provided to a Doppler signal analyzer for analysis.
