Patent number: 9270768Abstract: One or more interactions between a first user and a second user of a social networking system are identified. Each respective interaction of the one or more interactions is scored based on a group score and a time penalty. The group score is based on the number of users in the respective interaction and the time penalty is based on a time between a current time and a time of a last interaction between the first user and the second user. A relationship ranking that measures the first user's affinity towards the second user is determined, where the relationship ranking comprises one or more interaction scores. An indicator representing the relationship ranking is sent to a client for display.Type: GrantFiled: November 14, 2013Date of Patent: February 23, 2016Assignee: Path Mobile Inc Pte. Ltd.Inventors: David B. Morin, Shawn D. Fanning, Dustin R. Mierau, Daniel S. Dofter, Matthew M. Matteson, Mark Lewandowski, Mary Ann Brennan, Daniel Trinh, Mallory Paine

Publication number: 20140299055Abstract: Disclosed is a tape that includes a substrate having an adhesive layer applied thereto, and an edge coating applied to a masking edge of the tape. The substrate and the adhesive, together, define a first and a second masking edge of the tape. The edge coating includes a flocculating agent that is a polyvalent metal salt or an ionic polymer. The edge coating improves the ability of the tape to provide a sharp mask line after a paint, a varnish, a paint stripper, or other coating composition is applied to a surface where the tape is adhered.Type: ApplicationFiled: November 8, 2011Publication date: October 9, 2014Applicant: Intertape Polymer Corp.Inventors: John K.

Publication number: 20130339449Abstract: Systems and methods for tagging digital content are provided. In some embodiments, a method comprises receiving and storing personal data of a first user of an internet-based social network. The personal data of the first user can include one or more digital images or other digital content that the first user is willing to share with other users of the social network. Accordingly, a request from a second user of the internet-based social network can be received to view some of the digital content of the first user. A viewer image can be used to tag the digital content of the first user allowing the owner of the digital content to quick determine the viewers. The viewer image can be a personal profile picture, an image, an icon, an avatar (two-dimensional or three-dimensional), or other on-screen representation that includes a visual indicator of the second user.Type: ApplicationFiled: August 12, 2013Publication date: December 19, 2013Applicant: Path, Inc.Inventors: David B.
