Abstract: A power supply circuit includes a power converter, an input voltage source, and a clamping circuit. The power converter has an input pin, an output pin, and an enable pin. The input voltage source is electrically connected to the input pin, and provides an input voltage to the input pin. The clamping circuit is electrically connected to the enable pin of the power converter. When the input voltage increases to at least a threshold input voltage, the clamping circuit is configured to activate the power converter to provide an output voltage at the output pin. When the input voltage decreases below the threshold input voltage, the clamping circuit is configured to deactivate the power converter and prevent the power converter from being re-activated within a predefined time period.

Abstract: An oral cavity scanning device is provided in the invention. The oral cavity scanning device includes an image capturing unit, an IMU circuit and a processing unit. The image capturing unit obtains a first image and a second image. The IMU circuit obtains IMU information corresponding to the first image and the second image. The processing unit obtains a distance value between the first image and the second image. The processing unit uses a contour algorithm to obtain a first contour and a second contour. The processing unit obtains first sampling points according to the first contour and second sampling points according to the second contour. The processing unit uses a feature algorithm to find relative feature points between the first sampling points and the second sampling points. The processing unit uses a depth information algorithm to obtain the depth information of each feature point.

Abstract: A method of detecting leakage within a chassis includes mounting the chassis on a plate disposed in a sealed chamber and fluidly connecting, by a pipe, an interior space of the sealed chamber to a water tank such that a bottom end of the pipe is under a surface of water in the water tank. The method further includes determining, such as observing, whether bubbles are formed at the bottom end of the pipe due to pressurized air flowing into the pipe. The method also includes determining presence of a leak in the chassis due to pressurized air flowing between the chassis and the sealed chamber, before flowing into the pipe.
