  • Publication number: 20220019704
    Abstract: The present invention discloses a 3D shape internal hollowing form lightweight method based on function representation, and belongs to the field of computer-aided design. First, function representation is used and effective analytical calculation of shape optimization is explored; then, under the constraint of given external conditions, the stress structure design of a 3D object as well as the problems of center of mass, stand stability, tumbler design and buoyancy of an object are modeled by building an energy function model, and a corresponding discrete computation is given; finally, the above modeling problems are geometrically optimized to obtain an optimized internal shape of the object under given constraint conditions. The present invention greatly shortens the design and optimization cycles of this kind of cavity structures and can give theoretically optimal results.

  • Patent number: 10176232
    Abstract: Web search results and enterprise search results are combined into a single presentation. A search query is received from a user associated with a tenant of an enterprise cloud computing platform. Web search results are retrieved based on the search query. The Web search results are ranked and sent to the search engine user interface. An intent of the search query is determined. It is determined that the search query is related to the tenant's enterprise data. An instruction containing the search query keywords and intent is sent to the search engine user interface, and is configured to cause the search engine user interface to submit the keywords intent to an enterprise search engine within the enterprise cloud computing platform. A content template is communicated to the search engine user interface. The content template is configured to display enterprise search results received at the search engine user interface.

  • Publication number: 20090238502
    Abstract: A perforated large-size easy opening pouch is formed from a single sheet containing at least one layer of a film material, and the sheet forms a volume. The pouch also contains a seal containing a perforation. The perforation is completely surrounded by the seal. When a tear is initiated along the perforation, the tear propagates to a non-sealed portion of the pouch. A sealing jaw and a method for forming such a pouch is also described.
