Patent number: 9397974Abstract: A delivery assurance system for ensuring that people have an opportunity to view messages shared by authors to which they subscribe is disclosed. The delivery assurance system is configured to communicate with at least one author and a plurality of followers associated with the at least one author. The system in the preferred embodiment comprises a computer processor configured to receive a post from an author; transmit a first copy of the post to a plurality of users; determine if any of the plurality of users did not see the post; automatically transmit a second copy of the post to each of the plurality of users that did not see the first copy of the post; and remove the first copy of the post from a timeline of each user to which a second copy of the post was transmitted. Transmission of multiple copies of the messages, therefore, enables users to see a message regardless of when the author initially transmitted it.Type: GrantFiled: December 10, 2012Date of Patent: July 19, 2016Assignee: UBERMEDIA, INC.Inventors: William Gross, Girish Venkat, Dong Chang, Jamie Belsky

Patent number: 9087110Abstract: Systems and methods for generating a set of priority contacts based on their strength of relationship with a user. Contacts of users and communications from those contacts are aggregated across multiple online accounts into a single set of communications. An affinity score is calculated for each of the user's contacts based on adding up the total weight and frequency of communications with the user and a predetermined number of contacts having the highest affinity score can be identified as priority contacts. The affinity score is used to filter the news feed in a user interface display so that only communications from priority contacts are displayed in the news feed.Type: GrantFiled: December 2, 2013Date of Patent: July 21, 2015Assignee: MYLIFE.COM, INC.Inventors: Sumeet Rana, Dong Chang, David Wolfe

Publication number: 20140089306Abstract: Systems and methods disclosed herein relate to generating a set of priority contacts based on their strength of relationship with a user. Using the techniques introduced herein, contacts of users and communications from those contacts can be aggregated across multiple online accounts into a single set of communications in a centralized queue. The communications can then be analyzed to determine the category and frequency of the communications and weights can be assigned to each different category of communication based on a set of rules adapted to show the level of affinity of a particular contact with the user (and vice versa). An affinity score is calculated for each of the user's contacts based on adding up the total weight and frequency of communications with the user and a predetermined number of contacts having the highest affinity score can be identified as priority contacts.Type: ApplicationFiled: December 2, 2013Publication date: March 27, 2014Applicant: MyLife.com, Inc.Inventors: Sumeet Rana, Dong Chang, David Wolfe

Publication number: 20130246170Abstract: Embodiments of a search engine are disclosed that enable authors and third parties to influence the persistence and ranking of the author or the author's posts in search result listings using a bidding process or other compensation-based mechanism. In one embodiment, the search engine allows authors to submit bids in auction for ranking in order to keep their posts (or posts of other authors) visible to targeted searchers for a longer period of time than would normally be available. The bid amount, together with other attributes, can be used to determine the relevance and ranking of posts or authors provided in a search results page to a searcher. Embodiments of the search engine may be utilized with a microblogging service or a social networking service.Type: ApplicationFiled: May 8, 2013Publication date: September 19, 2013Applicant: UberMedia, Inc.Inventors: William Gross, Alexander Maleki, Jamie Belsky, Levon Z.

Patent number: 6326608Abstract: A polarization-type laser detection system is provided, which is capable of distinguishing between a reflected light signal from a target object and a back-scattered light signal from a mass of suspended particles in the air. This allows the laser detection system to be reliably operable under bad weather conditions when the air is filled with suspended particles. The laser detection system includes a laser means for producing a linearly-polarized laser beam which is the directed to a specified direction for target detection. When echoed back, the echoed signal is first polarized by an analyzer lens into a direction that is perpendicular to the direction in which the emitted laser beam is polarized. Further, a Fresnel lens is used for focusing the emerging light from the analyzer lens into a focal point where an optical detection module is mounted.Type: GrantFiled: July 9, 1999Date of Patent: December 4, 2001Assignee: Chung-Shan Institute of Science and TechnologyInventors: Her-Ting Wei, Guang-Ming Shle, Dong Chang
