  • Patent number: 11980446
    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: 11985784
    Abstract: A server information handling system is secured by a bezel that couples to an access location, such as an air vent at a front or rear face of a housing. The bezel includes a security structure having a lock and configured to couple directly at the front face or with a bezel extension at the rear face so that the server information handling system can use the same bezel with both a front face or rear face rack mount. The bezel has a lock integrated with the security structure, an air filter that fits over the security structure to filter air flowing into the housing, and a filter brace that captures the air filter by coupling to the security structure over the air filter. The filter brace attaches and detaches at the security structure when the security structure locks a server information handling system housing so that the air filter can be changed while the housing remains secure.
