Facebook is an American for-profit corporation and an online social media and social networking service based in Menlo Park, California. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. Facebook gradually added support for students at various other universities, and eventually to high school students as well. Since 2006, anyone age 13 and older has been allowed to become a registered user of Facebook, though variations exist in the minimum age requirement, depending on applicable local laws users may join common-interest user groups organized by workplace, school, hobbies or other topics, and categorize their friends into lists such as “People From Work” or “Close Friends”.

Patent history

Facebook was assigned 9 granted patents from Hewlett-Packard Company, recorded at the USPTO on February 15, 2010, and was assigned a previously published patent application on February 11, 2010. It was interesting that the patent filing’s focus was on protecting the private information of others given the history of the development of Facebook, and that of its predecessor, the short-lived Facemash. It would be interesting to see what other topics were covered in those patents, and made the following list, which includes information about the inventors, the abstracts from the patent filings, and some images from many of the patent applications.
Some patent applications given below:

• Patent no:- US20080046976
Abstract: A system and method for dynamically generating a privacy summary is provided. The present invention provides a system and method for dynamically generating a privacy summary. A profile for a user is generated. One or more privacy setting selections are received from the user associated with the profile.

The profile associated with the user is updated to incorporate the one or more privacy setting selections. A privacy summary is then generated for the profile based on the one or more privacy setting selections.

Patent no:- US20080033739
Abstract: Segmented community flyers are predicated upon segmented communities. Segmented communities are for those web-based users that appreciate the distinction between their “real life” friends in their local geographic communities and their “cyberspace” contacts, many of whom they have never met in person.

Further, those web-based users that do appreciate their “real life” friends in their local geographic communities need a way of communicating to many of these “real life” friends at once, without having to spend time preparing and sending multiple emails. Segmented community flyers advantageously accomplish such communication.

About technology:
1. A method comprising:
by a computing device, determining a maximum exposure time for capturing one or more image frames of a video clip, wherein:
the maximum exposure time is determined based at least in part on an amount of motion of the computing device as measured by a motion sensor; andthe maximum exposure time represents an exposure time below which the captured image frames are substantially free of motion-blur artifacts and above which the captured image frames exhibit motion-blur artifacts; and by the computing device, capturing the image frames, wherein each of the captured image frames has an exposure time that is less than or equal to the maximum exposure time.
