Patent number: 10249009Abstract: A social networking system provides a content feed to a client device associated with the user of a social networking system, the content feed including a plurality of content items. The social networking system identifies one or more missed content items, of the plurality of content items, that were part of the content feed and were not displayed by the client device. The social networking system generates a subsequent content feed that includes one or more content items that have not been previously provided to the client device and a missed feed unit that is associated with the one or more missed content items. In one embodiment, the missed feed unit, when selected, redirects the user to a new page that presents a different content feed including the identified missed content items. The social networking system provides the subsequent content feed to the client device for presentation to the user.Type: GrantFiled: July 28, 2017Date of Patent: April 2, 2019Assignee: Facebook, Inc.Inventors: Chao Ruan, Shilin Ding, Jiayi Zhu, Wenyuan Yu, Li Zhang, Gregory Matthew Marra, Andrew Chung, Zhiqiu Kong

Patent number: 7405027Abstract: Methods of preparing a liquid electrographic toner composition are provided, wherein a polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions is first prepared in a hydrocarbon reaction solvent, wherein the hydrocarbon reaction solvent comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL. Toner particles are then formulated in the hydrocarbon reaction solvent and dried. The dried toner particles are then redispersed in a carrier liquid that is different from the reaction solvent, wherein the carrier liquid comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL, to form a redispersed liquid electrographic toner composition. Preferred carrier liquids are silicone oils. Products and kits are also provided.Type: GrantFiled: October 31, 2004Date of Patent: July 29, 2008Assignee: Samsung Electronics CompanyInventors: Hsin Hsin Chou, Jiayi Zhu, James A. Baker, A.
