  • Publication number: 20250142073
    Abstract: A point cloud encoding method, decoding method, encoding device, and decoding device are disclosed. The point cloud encoding method includes calculating a distance from a first point to a parent point of the first point as a first distance; determining a point in un-encoded points closest to the first point as a second point, and calculating residual values on N coordinate components from the second point to the first point; encoding absolute values of the residual values on the N coordinate components from the second point to the first point; encoding signs of the residual values of the second point based on the residual values of the second point and the first distance. The present disclosure utilizes the geometry position relationship between points in a point cloud to encode the absolute values of residual values and the feasible signs of residual values, thereby improving the encoding efficiency of residual values.

  • Patent number: 10895814
    Abstract: A shifting-in/out mechanism includes a connecting block, flat spring made of two segments connected by a hinge, spring deflection assembly and wheel assembly. One segment of the flat spring is connected to the wheel assembly and the other is mounted, by the connecting block, on an object to be moved. The spring deflection assembly provides a driving force for deflecting the segment of the flat spring connected to the wheel assembly toward a movement supporting surface. A shifting-in/out device for a workpiece stage of a photoetching machine includes a bottom frame, air spring, air-cushion device and plurality of the mechanisms arranged on a lower or side surfaces of the bottom frame. In the mechanism, the flat spring has two segments hinged together. All locations of the flat spring that are stressed to cause deflection of the flat spring are substantially on a single line.

  • Publication number: 20120254809
    Abstract: Various methods for motion gesture recognition are provided. One example method may include receiving motion gesture test data that was captured in response to a user's performance of a motion gesture. The motion gesture test data may include acceleration values in each of three dimensions of space that have directional components that are defined relative to an orientation of a device. The example method may further include transforming the acceleration values to derive transformed values that are independent of the orientation of the device, and performing a comparison between the transformed values and a gesture template to recognize the motion gesture performed by the user. Similar and related example methods, example apparatuses, and example computer program products are also provided.
