Abstract: Methods and apparatus for additive manufacturing using extrusion and curing, and for multi-material spatially-modulated extrusion-based additive manufacturing are described, in which material composition and/or color can be varied locally to create abrupt transitions or controlled gradients, and in which objects may be fabricated from thermoset materials.

Abstract: Disclosed is an information collection system to collect sources of information relating to a subject from a plurality of users.

Abstract: Various embodiments of the present invention are directed to an Internet search engine with e-commerce functionality (“e-commerce search engine”). In one embodiment of the present invention, users can use the e-commerce search engine to locate retail items by typing in a key-word search. The search results displayed by the e-commerce search engine are vendor-website listings for vendors that sell retail items related to search terms. Some vendor-website listings may contain quick links through which a user can shop for, and purchase, retail items from the vendor through the e-commerce search engine, without being re-directed to the vendor's website. Transaction information is later relayed from the e-commerce search engine to the vendor. The vendor can then confirm the order and the shipping information with the user and complete the transaction.

Abstract: An improved castration loop for use in conjunction with a ligation tool is preformed from a section of surgical tubing to create a forward loop and a rearward loop. The preformed castration loop is created by crimping a deformable extruded aluminum clip to prevent the ends of the endless elastomeric loop from becoming separated. The forward loop is applied to an animal body part, and a second identical deformable extruded aluminum clip is crimped to adjacent sections of surgical tubing to prevent the elastomeric ligature material from slipping through the second extruded aluminum clip.
