Abstract: A welding quality detection system and a welding quality detection method are provided. A detection device applies a force to at least one weld point of a first welded object or a second welded object that are welded together. A displacement detector detects a displacement signal that varies with the force or time between the first welded object and the second welded object based on the force. A detection module receives or records the displacement signal and determines whether a gap exists between the first welded object and the second welded object based on a slope of the displacement signal, so as to detect the welding quality of the weld point quickly and precisely.

Abstract: The disclosure provides an ultrasonic wave acupuncture device, including an ultrasonic source, a liquid lens, an ultrasonic-source controller, a liquid-lens controller, and a power supply. The ultrasonic source is adapted to generate ultrasonic waves. The liquid lens is adapted to focus the ultrasonic waves. The ultrasonic-source controller is electrically connected to the ultrasonic source and generates ultrasonic-source voltage pulses to control the frequency, amplitude, and pulse length of the ultrasonic waves generated by the ultrasonic source. The liquid-lens controller is electrically connected to the liquid lens and generates liquid-lens voltage pulses to control the focal length of the liquid lens to focus the ultrasonic waves on a specific location. The power supply is electrically connected to the ultrasonic-source controller and the liquid-lens controller, so as to provide voltage to the ultrasonic-source controller to control the ultrasonic source, and to provide voltage to the liquid-lens controller to control the liquid lens. The ultrasonic-source voltage pulses generated by the ultrasonic-source controller and the liquid-lens voltage pulses generated by the liquid-lens controller are aligned with each other.

Abstract: A computer-assisted needle insertion method is provided. The computer-assisted needle insertion method includes the following steps. A first machine learning model and a second machine learning model are obtained. A computed tomography image and a needle insertion path are obtained, a suggested needle insertion path is generated according to the first machine learning model, the computed tomography image, and the needle insertion path, and the needle is instructed to approach a needle insertion point on a skin of a target. The needle insertion point is located on the suggested needle insertion path. A breath signal of the target is obtained, and whether a future breath state of the target is normal is estimated according to the second machine learning model and the breath signal. A suggested needle insertion period is output according to the breath signal in response to determining that the future breath state is normal.
