  • Publication number: 20220369935
    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.

  • Patent number: 11304414
    Abstract: An insect-trapping device includes a container, a funnel element, two photo interrupters and a controller. The container has an inlet and an accommodation space. The funnel element is placed on the inlet to extend into the accommodation space of the container. The photo interrupters are arranged within an inner passage of the funnel element along a long axis direction of the inner passage for sensing whether at least one insect passes through the inner passage from the inlet. The controller is electrically connected to the photo interrupters for counting the insects passing through the inner passage according to the photo interrupters.

  • Patent number: 11288470
    Abstract: A method of automatically triggering scanning operation through specific motion includes steps as follows. A specific motion trajectory of a scanning device is sensed to determine whether the scanning device is moved along a predetermined path. If so, an image sensor of the scanning device is switched on. A determination is made as to whether the scanning device is moved down to a lower position. If so, the image sensor of the scanning device is switched off.

  • Patent number: 11278673
    Abstract: A recording device for injection device includes a housing, a viewing window, a photographic module, a light splitting element and a signal transmission device. The housing is removably mounted on a dose scale window of an injection device. The viewing window is formed on a surface of the housing, and a viewing path is formed from the viewing window to the dose scale window. The photographic module is located on the housing, and provided with an image-capturing optical axis which is perpendicular to the viewing path. The light splitting element is located at an intersection of the viewing path and the image-capturing optical axis for guiding information located in the dose scale window to the photographic module and the viewing window, respectively. The signal transmission device is electrically connected to the photographic module for transmitting signals of the photographic module to an external device.
