| 20090248810 | SYSTEMS AND METHODS FOR QUERYING STATUS OF PEER-TO-PEER MULTIMEDIA CONNECTIONS IN COMMUNICATION SYSTEMS - Status information associated with a peer-to-peer multimedia connection can be queried by the network. A queried terminal can provide responsive status information including, for example, a type and/or amount of data which has been sent over the peer-to-peer multimedia connection and/or a type and/or amount of data which is yet to be sent over the peer-to-peer multimedia connection. This status information can, for example, be used to assist in charging or billing the customer using the multimedia service. | 10-01-2009 |
| 20100077057 | File Transfer in Conference Services - Systems, methods, devices and software according to these exemplary embodiments provide techniques for transferring files in a conference. Upon receiving a request for a file transfer to multiple endpoints, media descriptions associated with those endpoints can be modified and used to transmit invitations to those endpoints for the file transfer. Based on the responses to the invitations, the file transfer may then proceed. | 03-25-2010 |
| 20110246581 | Method and System for Group Event Communications - A method and an Event Tracking System (ETS) are provided for group communications. The method allows subscribing with an Event Organizing System (EOS) for updates to a group event instance comprising a group of users and an event related to the group, e.g. a hockey match. The method further allows receiving from users subscriptions to the updates of the group event instance. Responsive to subscribing with the EOS for the updates to the group event instance, the ETS receives from the EOS an update notification related to the group event instance notifying of a group event update (e.g. an update of the group membership and/or of the event), and responsive to the user subscriptions with the ETS, the later sends out an update notification message to each one of the users notifying of the group event update. In one embodiment, the update notifications sent out to users are personalised, e.g. based on the user's location or advertisement preferences. | 10-06-2011 |
| 20110307933 | SYSTEMS AND METHODS FOR IMPLEMENTING SERVER SIDE PUSH MECHANISMS FOR INTERNET PROTOCOL TELEVISION (IPTV) UPDATES - Systems and methods provide for transmitting updates in an Internet Protocol Television (IPTV) environment towards a client. The method includes: maintaining the updates in a data hierarchy of updates; receiving a first message identifying a client; retrieving information associated with the client; determining which updates are relevant to the client by matching the information associated with the client to the data hierarchy of updates; and transmitting a second message toward the client with information associated with the determined updates. | 12-15-2011 |

| 20100243194 | Stationary side dam for continuous casting apparatus - Exemplary embodiments of the invention provide a side dam for a continuous metal casting apparatus having elongated opposed casting surfaces forming a casting cavity. The side dam has an elongated upstream part and an elongated downstream part that are mutually laterally pivotable, and a smooth metal-contacting side surface extending continuously from an upstream end to a downstream end of the side dam. The surface has regions thereof formed on the upstream part and the downstream part. Mutual pivoting of the upstream part and the downstream part of the side dam enables the regions of the smooth metal-contacting side surface to be moved out of mutual coplanar alignment. The side dams can therefore be used to form either a convergent or divergent casting cavity to assists the casting procedure and to enhance the properties of the cast article. | 09-30-2010 |
| 20100243195 | Side dam blocks for continuous strip casters - Exemplary embodiments of the invention relate to a side dam block for a continuous metal caster apparatus. The block comprises a body of molten metal resistant material having a metal-contacting surface. The metal contacting surface has a plurality of indentations therein, the indentations having openings at the metal-contacting surface dimensioned to prevent penetration of molten metal into the indentations under casting conditions. Due to a smaller area of direct contact between the molten metal and the surfaces of the blocks, the blocks extract less heat from the molten metal than conventional blocks and help to reduce so-called “dog-bone” and “sink” type deformation of the cast article. | 09-30-2010 |
| 20100243196 | Continuous casting apparatus for casting strip of variable width - Exemplary embodiments of the invention provide a casting apparatus for continuously casting a metal strip article (e.g. a twin-belt metal caster or a twin-block metal caster). The apparatus has a casting cavity defined between a pair of moving elongated opposed casting surfaces, and the casting cavity has an entrance and an exit aligned in a direction of casting. The casting cavity is also provided with a molten metal injector at its entrance, the injector having an internal metal channel including a downstream opening for introducing molten metal into the casting cavity, and a pair of side dams at each lateral side of the casting cavity for confining molten metal from the injector within the cavity. At least one of the side dams comprises an elongated element that is movable laterally relative to the direction of casting during a casting operation. The elongated element extends in the direction of casting from the injector longitudinally between the casting surfaces at least to a downstream position within the casting cavity where the metal adjacent the element is laterally self-supporting. | 09-30-2010 |
| 20100326618 | Method of and apparatus for measuring separation of casting surfaces - Exemplary embodiments of the invention provide a method of measuring the separation of moving confronting casting surfaces within a casting cavity of a casting apparatus. The method involves attaching at least one separation sensing device to a first one of a pair of confronting casting surfaces outside the casting cavity and then moving the casting surfaces to advance the sensing device(s) through the casting cavity while operating the device(s) to generate signals. The signals are monitored continuously or at regular intervals and converted to distance measurements representing separation of the surfaces at a plurality of positions through the casting cavity. Other exemplary embodiments provide apparatus for carrying out the method, and methods of measuring irregularities of casting belts or the like. | 12-30-2010 |
