Abstract: Embodiments of the present invention provide methods and systems for content providers, such as musicians, to register upcoming events, such as concert events, upload songs, etc. Users of a social network service may then browse venues and content providers. Upon selecting one of the providers, the social network service retrieves the songs registered by the content providers into a playlist for the user. In some embodiments, users may search an area to find and create a playlists of multiple content providers. The user could thus create a playlist by venue, by day, etc. In addition, each of these created playlists can be shared with others on the social network service. The social network service may also auto-generate playlists based on genre, date, artist, etc. A stream of the songs may then be delivered to the user according to the playlist they choose and the various music services that they subscribe.

Abstract: A conductor assembly for a medical device lead includes a helically coiled conductor including a plurality of turns having a coil pitch and an outer diameter and consisting of one filar having a filar diameter. The coil pitch and outer diameter are selected based on the filar diameter to minimize heating of the helically coiled conductor in the presence of an MRI field. A polymer sheath is formed about the helically coiled conductor such that the coil pitch of the unifilar helically coiled conductor is maintained. The polymer sheath is configured to increase a torque transmitting capacity of the helically coiled conductor.

Abstract: A method and computer system including launching a dialogue window for two users to communicate with one another via respective client devices relating to a particular subject. A search query is received from an additional user including a keyword associated with the particular subject. In response to the request, a backlog of a recent discussion between the two users relating to the particular subject is retrieved and provided to the additional user, wherein the backlog includes a suggested link relating to the recent discussion.

Abstract: Methods and systems to manage users of a social network. The method includes receiving, at a server, a request to contact a user from another user of a social network based on a selected one of a plurality of associated identity resources of the user known by other users. The method also includes restricting views of other users for the identity of the user to the selected one of the plurality of associated identity resources.

Abstract: Users searching for common subject matter on a computer network are identified and enabled to communicate with one another, such as by engaging in an on-line chat. The users' search queries are transmitted to a server and processed to identify which users are searching for common subject matter within a time window. A dialogue such as an on-line chat is launched and the identified users are invited to join. The users may preview the chat before joining. The users can share links to resources such as web pages and provide annotations to accompany the links. Additionally, the users' search queries may be shared in the chat. The functionality may be provided by a plug-in to web browser software, or by an executable script embedded in a web page of search results.

Abstract: Described is an implantable lead comprising a flexible body extending between a proximal end and a distal end and a distal assembly coupled to the distal end of the body. The distal assembly includes a housing having a distal end and a proximal end, the proximal end fixedly coupled to the distal end of the lead body, a coupler rotatably disposed within the housing, the coupler having a proximal end and a distal end, and a helical electrode fixedly secured to the distal end of the coupler. The helical electrode comprises a proximal axial length portion that comprises a non-degradable material, and a distal axial length portion that comprises a biodegradable material. The coupler and the helical electrode are configured to rotate and therefore translate relative to the housing.

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: Methods and systems can manage 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 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.

For example, in some embodiments, the user is permitted to perform various functions, such as, browsing the service, navigating external links, and viewing various pages of other users and groups. This information and links may be transitioned over if the user wishes to establish a permanent account.

Abstract: An optical surface inspection system provides dark-field detection avoiding ghost images and without capturing, stray, reflected or re-scattered light. The system includes an illumination system that generates an illumination spot on a surface under inspection collecting lens that collects substantially all light scattered from the surface under inspection from the illumination spot. The system also includes a light guide with a first end having a numerical aperture matched to an exit aperture of the collecting lens and a field of view matched to the illumination spot, and a second end coupled to a detector.

Abstract: An optical measuring system includes a scatterometer in which an illumination beam is provided through an aperture in a lens used to collect light for the scattering detection. The void may be a slit in the lens, a missing portion along an edge of the lens, or another suitable void. Another detection channel may be provided to detect light returning through the void in the collecting lens, for example, a profilometer may be implemented by detecting interference between reflected light returning along the illumination path and light from the illumination source.

Abstract: An optical inspection system includes a fluorescence channel that detects fluorescent behavior (or lack thereof) of artifacts present on a surface under inspection and at least one other optical channel for determining a characteristic of the surface under inspection in an illuminated spot. The other optical channel may be a height measuring channel, such as an interferometric channel or a deflectometric channel, the other optical channel may be a scatterometric channel, or both height measurement and scatterometry may be employed in combination as a three channel system. The presence of absence of fluorescent behavior may be used to correct assumptions about or determine a type of artifact detected by scatterometry, and may be used to correct the polarity of a height measurement made by a height-measuring channel.
