Apr 18, 2022

Appl. No.:

17/723334

Inventors:

Jonathan Chang - South Pasadena CA, US

International Classification:

A61B 17/88
A61B 17/28
A61B 17/80

Abstract:

An orthopedic clamp to assist in reducing the displacement between bone ends of a fracture, and to position a fixation device, during open fracture reduction surgery is described. The clamp includes a holder to hold the fixation device against the bone. The clamp may also swivel in relation to the holder while the position of the fixation device remains unchanged. The clamp may be modular so that components thereof may be released and/or attached.

International Classification:

G06F 17/30
G06Q 50/00
H04L 29/08

Abstract:

In one embodiment, a computing device accesses a social graph comprising nodes and edges connecting the nodes. Each of the edges between two of the nodes represents a single degree of separation between them. The nodes include user nodes corresponding to users of an online social network, and concept nodes corresponding to places. A particular place corresponds to a particular concept node, and corresponds to an associated location and a perimeter. A number of check-ins are received, each check-in being associated with the particular place and having a geographic location. Each check-in corresponds to an edge of the social graph between a user node and the particular concept node. Based on the received check-ins the computing device determines whether to update the associated location and the perimeter.

International Classification:

G06F 17/30

Abstract:

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users of the social networking system using the metapages generated for the concepts. Aggregated social information may be presented to users of the social networking system viewing a page associated with a metapage. In one embodiment, a best page may be determined for a user based on information about the user.

Abstract:

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users of the social networking system using the metapages generated for the concepts. Aggregated social information may be presented to users of the social networking system viewing a page associated with a metapage. Information presented on external websites may be used to link pages across multiple domains with a metapage generated on the social networking system. In one embodiment, the information on other external websites associated with the metapage may be presented as links on the pages associated with the metapage. Feedback from users may be used to include or exclude pages from being associated with a generated metapage. In one embodiment, a best page may be determined for a concept embodied in multiple pages on the social networking system using a hierarchy of rules. In another embodiment, a best page may be determined for a user based on information about the user. In yet another embodiment, social context information may be provided on a page associated with a metapage for a viewing user that shows expressions of interest by other users on the page and other pages associated with the metapage.
