  • Patent number: 11597552
    Abstract: An actuator system for fabricating a cavity within thermoplastic material includes a plurality of actuators arranged in an array. When dimensions of an item are determined, the actuator system may be programmed with data regarding such dimensions to fabricate a cavity for the item. A subset of the actuators, and distances by which each of the actuators is to be extended, may be selected based on dimensions of the item, in order to fabricate a cavity within the thermoplastic material that may accommodate the item therein. Additionally, the actuators and the distances may be selected based on intrinsic or extrinsic data regarding the item, and a cavity fabricated within the thermoplastic material may include one or more buffer zones or protective regions that are specifically formed with respect to aspects of the item.

  • Patent number: 9892426
    Abstract: Disclosed is a system and method for presenting content in response to receiving a portion of a search query. A computing device receives, over a network from a user computer, a portion of a search query submitted by a user in a search query entry area. The computing device receives, from a search suggestion module, one or more search suggestions related to the portion of the query. The computing device transmits, to the user computer, the one or more search suggestions for display in a search suggestion region, the search suggestion region displayed differently than a search results area. The computing device transmits a search suggestion of the one or more search suggestions to a rich content module. The rich content module generates rich content related to the transmitted search suggestion. The computing device transmits, to the user computer, the rich content for display in the search suggestion region.

  • Patent number: 9647183
    Abstract: There is provided a method of fabricating a vertical light emitting diode which includes forming a light emitting diode structure. Forming the light emitting diode structure includes: forming a first material layer of a first conductivity type, forming a second material layer of a second conductivity type, forming a light emitting layer between the first material layer and the second material layer, and forming a plurality of generally ordered photonic nanostructures at a surface of the first material layer through which light generated from the light emitting layer is emitted for enhancing light extraction efficiency of the vertical light emitting diode. In particular, forming a plurality of generally ordered photonic nanostructures includes forming a self-assembled template including generally ordered nanoparticles on the surface of the first material layer to function as a mask for forming the photonic nanostructures at said surface of the first material layer.
