Patent number: 11597552Abstract: 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.Type: GrantFiled: May 22, 2020Date of Patent: March 7, 2023Assignee: Amazon Technologies, Inc.Inventors: Brian Stuart Hoffman, Cory Richard Boudreau, Todd Ethan Brunner, David C. Franchino, Alexandra Kay Hartford, Vivian Lin, Mohan Mahadevan, John Gaetano Matrecano, Alexandra Surasky-Ysasi, Timothy Alan Talda

Patent number: 9892426Abstract: 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.Type: GrantFiled: November 14, 2016Date of Patent: February 13, 2018Assignee: EXCALIBUR IP, LLCInventors: Ethan Batraski, Vivian Lin Dufour, Aarti Parmar, Shenhong Zhu, Olivia Franklin
