Title: Streaming of media file data over a dynamically variable bandwith channel
IPC: H04L12/825
Filed: 2000-09-20
Abstract: A method of transmitting data streams over a variable bandwidth channel, comprising modifying the quantity of data to be injected into the channel to accord with a measured capacity or bandwidth of the channel. An input stream is passed through a plurality of parallel compressors 40.1-40.4 which each produce an output stream of a different rate to the other streams. Each stream preferably comprises key or reference frames and delta frames. The reference frames are synchronized between the streams so that a data unit in one stream contains the same information as the corresponding data unit in another stream, but is compressed to a different extent. A data stream for transmission along the channel is produced by selecting data units from more than one compressor output stream so as to produce a stream which makes optimum use of the available channel bandwidth. In one embodiment the duration of the data units are one of a group comprising fixed predetermined durations and duration determined by changes in the channel bandwidth. The method is useful in sending multimedia data streams such as audio and video over a channel such as a cellular telephone network or the internet.

Title: Fire and explosion suppression
IPC: A62C4/02
Filed: 2002-03-28
Abstract: A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) or other water mist generating means at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). Separation of the mist production from the actual discharge of the mist, and the entraining and transporting of the mist between these two stages at high pressure and high velocity, produces an output mist of very small droplet size which is carried by the entraining and transporting high pressure gas into the area to be protected, enabling a total flooding capability.

Title: System and method of managing supplementary features in the presence of a proxy switch in a mobile communications network
IPC: H04W76/02
Filed: 2001-11-21
Abstract: A proxy switch, communication methods, and communication logic for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload offload mobile traffic it provides a platform for new communication services. The proxy switch includes signaling message handling logic that receives signaling messages from the MSC and BS in accordance with a mobile signaling protocol. State logic maintains state information of call sessions and mobile stations (MSs) used within the mobile communications network. Message interception logic detects whether a signaling message from an MSC is a new call originating message and if an MS addressed in such a new call originating message is involved in a call. The message interception logic also prevents the new call originating message from being forwarded to the BS servicing the addressed MS. Message conversion logic converts the new call originating message to a feature notification message, and message transmission logic issues the feature notification message to the BS servicing the addressed MS.

Expiration of the acknowledgment timer indicates a missing packet in the second direction. The method determines if a TCP packet is missing in the first direction, in which case the method stores the evaluated TCP packet in the list and creates a retransmission timer indicating a maximum time to wait until treating the missing TCP packet as lost. Expiration of the retransmission timer indicates a missing packet in the first direction.

Patent GB-8825192-D0 (GB)
Title: Spilt gain multimode ring laser gyroscope and method
IPC: G01C19/68
Filed: 1988-10-27
Abstract: A ring laser gyroscope uses a lasing-mode suppression technique to circumvent frequency locking rather than more common frequency biasing methods. The device operates with a four-mirrored nonplanar optical path that allows left and right circularly polarized, on-axis modes to lase in each direction when an included gaseous gain medium is electrically discharged. A uniform axial magnetic field is applied to the gain region in order to produce a splitting of the gain curve into two parts separated in frequency by the cavity free spectral range. By small adjustments to the cavity length the two gain curves are centered about consecutive cavity longitudinal mode sets, each consisting of four modes. Consequently only two modes from each set can lase, thus creating a four-mode ring laser gyroscope with arbitrarily large lasing mode frequency spacings controlled primarily by the cavity geometry. The device may be configured to operate with a single isotope of neon in the gain medium. A simple magnetic field servo mechanism provides a high degree of immunity to external magnetic field charges.
