Abstract: The present invention relates to a medical system using an interventional elongated medical device having an optical fiber configured for optical shape sensing of the medical device. The system comprises a detection unit configured to detect a confined manipulation section along the medical device for manipulation by a user without an interaction interface arranged on the medical device and an analysis unit configured to analyze a user manipulation applied to the manipulation section based on optical shape sensing of the medical device in the manipulation section and to trigger an event in the medical system, if the analysis unit identifies the user manipulation in the manipulation section as a specific manipulation associated with the event to be triggered.

Abstract: Meta data accompanying a content broadcast includes an identifier of a group of peers on a P2P network. The group provides or shares a service to enable peers to connect and interact via the P2P network within the context of the broadcast.

Abstract: The invention provides a method and apparatus for more efficient searching peer to peer networks for data. Large peer to peer networks comprise millions of peer clients, or just briefly peers, having enormous amounts of data objects available. Searching all peers takes a lot of time, therefore a small group—private network—is formed within the peer to peer network. Peers for this private network are selected when they satisfy at least on criterion. This criterion relates to for example subscriptions of the peer to data delivery services or to the search query. The private network or networks may be formed upon start-up of the apparatus according to the invention or even right after submitting a search query.
