Abstract: Embodiments of the present invention provide methods and systems for allowing users to efficiently create new accounts in an online service. The new account creation scheme allows users to begin using aspects of the online service before creating an account. The user is provided a temporary account and, in the event they choose to finalize joining the service, the user is permitted to save settings from their temporary account. For example, in some embodiments, the user is permitted to perform various functions, such as, browsing the online service, navigating external links, and viewing various pages of other users and groups. The user may also be allowed to collect information on other members that they are interesting and may be offered a temporary homepage where the user can view the activities of these other members. The temporary home page allows the potential new user to immediately begin using the services of the social network service without having to specifically request a new account.

Abstract: Embodiments of the present invention provide a system and method for logging a client into an internet service using a preexisting service. In order to login, the user may select a link that triggers the service to send login information to the user via a preexisting service, such as instant messaging or email. In some embodiments, the user is sent a link via their preexisting service. The user then logs into the service by selecting the link.

Abstract: Embodiments of the present invention allow users to tag a multimedia program or stream with data or pointers to external information related to content of the multimedia program. Users in a social network may tag various aspects of the content, such as a particular actor, a type of car, jewelry, a location, a phrase, etc. This tagging information may then be linked to various websites that provide further information about the tagged content and may be keyed to video offset times.

Abstract: Embodiments of the present invention provide an automated scheme for identifying high/low value content. Playback data from users in a social network may be periodically submitted by users of the social network. The playback data indicates segments of content, such as audio or video that the user has skipped over or tagged as low value. The playback data may also indicate segments of content that the user has repeated or tagged as high value. The playback data is then analyzed in aggregate and various clips are identified. In addition, the playback data may be compiled and organized among the users for future use. The playback data may be used to indicate segments of high/low interest to peers in the social network or to arbitrary users.

Abstract: Embodiments of the present invention allow a user to master the music played among a social network. Users of the social network subscribe to the master's session and synchronize their media player under control of the master. The master then distributes various selections of music and controls their playback. The master may also add other data, such as voice over or images, to accompany the playback.

Abstract: Embodiments of the present invention provide an aggregated event stream that indicates activities to a user across a range of online services. Embodiments may include a web site, a client application, or mobile device. In particular, a display is provided to a user that indicates various events in a “stacked” format. Each block of the stacked format represents one or more events originating from the user's own activities or activities of the user's contacts in their social network. Activities may originate from accounts on other online services that the user linked to their account or profile. The stacked format is updated in substantially real time to provide the user a sense of the activities of their social network around them.

Abstract: Embodiments of the present invention provide users with suggested content that is preloaded on a media player. The suggested content is selected based on playback data from individuals and groups in a social network or playback data from anonymous users, or explicit suggestions from peers of the user in the social network, such as friends or family. The user may set aside space on their media player, such as a DVR or PC hard drive. A service then populates this space with suggested content. For example, the user may elect to populate this space with shows that their friends are watching, automatically. In addition, embodiments of the present invention allow users to track and create recommendations of content and to automatically schedule recording of showings of this content. The user may automatically record everything suggested, or require the user make selections. The present invention also provides for automatic selections, based on content type, time of day, or a random pattern.

Abstract: Embodiments of the present invention provide a mechanism for automatically creating a playlist for a user. In particular, data indicating music played by other users in the user's social network is collected. Music is then selected from this data and gathered from a music service in which the user subscribes, such as iTunes, Yahoo Music, etc. The service then builds the playlist with the gathered music.

Abstract: Embodiments of the present invention provide a simple, bi-directional control that allows the user to express one of two opposing opinion on a particular item and make a comment. For example, the user may be provided a bi-direction widget that indicates whether a user loves or hates a particular subject.

Abstract: A resonant ellipsometer and method for determining ellipsometric parameters of a surface provide an efficient and low-cost mechanism for performing ellipsometric measurements. A surface of interest is included as a reflection point of a resonance optical path within a resonator. The intersection of the resonance optical path with the surface of interest is at an angle away from normal so that the complex reflectivity of the surface alters the phase of the resonance optical path. Intensity measurements of light emitted from a partially reflective surface of the resonator for orthogonal polarizations and for at least two effective cavity lengths provide complete information for computing the ellipsoidal parameters on the surface of interest. The resonator may be a Fabry-Perot resonator or a ring resonator. The wavelength of the illumination can be swept, or the cavity length mechanically or electronically altered to change the cavity length.

Abstract: Diagnostic codes from a vehicle or other system in transit are transmitted to an opportunity server. The opportunity server searches for potential providers according to user preferences, specifications of the system in transit, and location of the provider in relationship to the travel itinerary of the mobile system. Requests for bids are issued to potential providers, and offers are received and coalesced from the providers. The operator of the vehicle is presented with one or more coalesced offers. Upon selection of an offer by the operator, the service is scheduled, including arranging for parts, personnel and facilities.

Abstract: Embodiments of the present invention provide methods and systems for managing the multiple identities used by a user. The user's existing contact lists, website accounts, buddy lists, and the like are analyzed to determine the identities used by the user. A graph is then constructed in order to track and integrate the multiple identities of the user in a social network. The social network graph may then be used by a social network overlay so that the user can share information across their different identities with different users that only know some of the user's multiple identities.

Abstract: Embodiments of the present invention provide methods and system for dynamically sharing multimedia content information. In particular, embodiments of the present invention provide a “live social context” in which users can share multimedia content information, such as a website, a stream, a music file, and the like. Upon finding multimedia content that a user would like to share with others, the user may select a “share” function, for example, by selecting a button on their browser that initiates a dialog window and permits the user to invite other users into a discussion. The invitations may then be sent to these users across different services. In addition, the invitation may include content, such as a text comment or file that the user has added. The recipient users receive a live notification of the invitation and may then participate in an online discussion with the user.

Abstract: Embodiments of the present invention provide methods and systems that allow users to share information about their recent activities with other users. In particular, as users receive and/or share multimedia content with other users, information that indicates the locations of this content, such as a website, playlist, or file, is passively tracked and logged. This information may be formatted into a viewable form, such as a web site or web log, and cooperatively shared with other users. Users may then incorporate the multimedia content played by other users into their own library. Users may also elect to synchronize their multimedia content with other users. For convenience, multiple locations for the same multimedia content may be determined when it is logged and tracked. Users may obtain the multimedia content using one or more of their existing accounts with a provider at their own discretion.

Abstract: Embodiments of the present invention provide methods and system for allowing an open overlay service for a social network to interface with other online services. In particular, the open overlay service configures its clients to make requests on behalf of the social network. Responses to the requests are routed back to the open overlay service and the information is then provided to the social network. Since the requests come from the client the online services will simply treat them as normal requests, and thus, the open overlay service can seamlessly integrate with a user's online services.

Abstract: Embodiments of the present invention provide a platform for an open overlay for online services, such as social networking sites, that permit users to share and leverage information within a single context. In some embodiments, the single context is implemented as a web site that is accessible to a social network of users that are known to each other. Systems and methods are provided that share and forward information for the users' online services within the single context. Client applications are provided that serve as an open overlay for the user and permit the user to seamlessly utilize the services of multiple online services within a single context. In some embodiments, the users' existing account identities and security information are utilized alone or in combination, and thus, the users are not required to establish a separate or new account for accessing the open overlay service.

Abstract: A Fabry-Perot resonator apparatus and method including an in-resonator polarizing element improves detection/measurement sensitivity of an optical system, provides both fields at a single end of the resonator, and overcomes other structural and performance limitations of particular optical systems. A polarizing element, which may be a quarter-wave plate, a 45-degree Faraday rotator or other polarizing element capable of converting between linear and circular polarizations and back, is placed in the resonance path of the Fabry-Perot resonator. The polarizing element effectively doubles the cavity length and orthogonally isolates forward from reverse reflection rays within the resonator, eliminating interference between rays and providing isolated bright and dark fields at each end of the resonator.

Abstract: A three-dimensional imaging resonator and method therefor provides improved surface height measurement capability in optical measuring systems. A resonator including a surface of interest in a resonant image path is coupled to an external multi-pixel detector that detects an image of intensity of light reflected from or transmitted through the resonator. An imaging system is included in the resonator to image a region of a surface of interest on another reflector forming part of the resonator. By changing an effective cavity length of the resonator, the image is “scanned” in a direction perpendicular to the other reflector and a processing system stores information corresponding to resonance peaks to achieve a mapping of feature height above the surface of interest. The resonator effective cavity length can be changed by sweeping the illumination wavelength or by mechanically or otherwise altering the optical length of the resonator.

Abstract: Embodiments of the present invention provide methods and system for “borrowing” and giving back a window from one computer to another. Borrowing refers to actions performed by one computer to temporarily obtain and control a window from another computer.
