Title: Synchronising threads which branch over synchronisation points
Inventor: YOONG-CHERT FOO
IPC: G06F9/45
Filed: 2007-07-04
Abstract: During compilation for execution on a multithreaded processor, synchronisation or rendezvous point instructions which follow a branch are checked to ensure that when threads are subsequently executed the synchronisation points function correctly. If a thread contains an instruction to branch over a rendezvous point the compiler checks to see that all alternative branch paths include a corresponding rendezvous point at the branch target and if they do not a rendezvous point is inserted to ensure that the synchronisation point is not missed. During subsequent execution when a thread reaches a synchronisation point, it waits until the remaining threads reach corresponding synchronisation points. When all the threads have reached the corresponding synchronisation points, they all resume execution. The threads may have a bit in a status register which indicates whether the thread is paused. The bit may be checked repeatedly to see if the threads have been paused. The processor may comprise a control core and a plurality of data processing pipelines. The processor may be adapted for media processing applications.

Title: Calling IP telephone extensions across networked exchanges
Inventor: FUSE TAMIKAZU
IPC: H04L12/70
Filed: 2007-08-14
Abstract: A telephone system 1 includes a plurality of exchanges 1,2,3 interconnecting a plurality of communication terminals IPT 110, 100, 210, 200, 300 through a communication network NW. Users are able to log-in to any communication terminal such that their extension number is assigned to the terminal at which they logged in. Each exchange includes a database 1b, 2b associating exchange ID's (Node Id's) with their corresponding network addresses and a database 1a, 2a associating each extension number with an exchange ID. When a user at a first terminal initiates a call to a second terminal, the exchange associated with the first terminal looks up the exchange ID associated with the called extension number and uses this ID to look up the IP address of the exchange with which the extension number is registered. The exchange then notifies the first communication terminal of the IP address of the second communication terminal's exchange and the first terminal sends a reconnection request to that IP address to thereby set up a call with the second terminal. May be applied to an IP telephone system comprising a plurality of networked PBX's.
Patent GB-2441448-A (GB)
Title: A fixed time step dynamical solver for interacting systems
Inventor: JOS STAM
IPC: G06F17/50
Filed: 2006-03-13
Abstract: The present invention is a particle position solver that allows particles to reach an end of a fixed time, time step in an invalid state and which are then pushed toward a valid state. This allows the solver to continue the simulation while the simulation results move toward a valid behavior. Particle collision calculations are simplified by adopting non sequential model ignoring some collisions or combining them. The speed of the simulation is also improved by performing some operations outside the solver calculation loop and by using specialized data structures.

Title: Reconfigurable quality of service monitoring for messaging in mobile communications networks
Inventor: TRAPP THORSTEN
IPC: H04W24/00
Filed: 2008-01-18
Abstract: In mobile environments, packet transmission services suffer from packet losses due to e.g. inadequate received signal quality, which is caused by the time and frequency selectivity of the mobile radio channel and by imperfections of mobile terminals, but also due to time-outs and entailed packet deletions, forced by protocols in the signaling domain of the infrastructure of a mobile communications network. To reduce the impact of packet losses and, hence, to improve the quality of packet transmission services, such as e.g. the Short Message Service (SMS) deployed in GSM (Global System for Mobile Communications) and in GPRS (General Packet Radio Service) based mobile communications networks, a quantitative analysis of the Quality of Service (QoS) in the signaling domain is mandatory. For this reason, appropriate additional QoS parameters, which complement the presently existing set of QoS parameters defined by e.g. ETSI, are needed. In this communication, the authors propose such QoS parameters and apply them to the SMS in GSM networks. Furthermore, a system framework for QoS monitoring, alerting and reconfiguring an SMS Center is presented. The system framework operates near real-time and, therefore, facilitates the reduction of the tumaround time needed for necessary reconfigurations at the SMS Center to maintain a high QoS level. Also, selected monitoring results gathered during real world network operation are presented and discussed.

Title: Circuit arrangements applicable to signalling systems utilising currents obtained from elements such as photo-electric cells
IPC: H04L17/14
Filed: 1939-03-31
Abstract: 527,103. Valve amplifiers; copying telegraphy. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1939, No. 10116. Convention date, May 17, 1938. [Classes 40 (iii) and 40 (v)] Direct-current impulses, such as those produced from a photoelectric cell in telegraphy, are converted into alternating currents with a minimum of transients, and means are provided (a) for limiting the amplitude of the output, and (b) for preventing the passage of waves below a predetermined value, for instance when transmitting images without half-tones. Light from a lamp 1 passes through an aperture or " chopper " 3 on to a photo-electric cell 2 connected to a valve 5 which is resistance-capacity coupled to an amplifier 9. The impedance of the condenser 7 is made much greater than that of the resistance 6, and the time-constant of the condenser 7 and resistance 8 is made small relatively to the signal frequency. The charging of the condenser 7 then produces an alternating potential across resistance 8, and the valve 5 acts as a converter (not an amplifier) and transients are reduced. Fig. 2 shows a limiter circuit for the output. So long as the peak-potential induced by the amplifier 91 across the secondary winding 12 is less than the difference of potential across the terminals of resistances 13, 14, the diodes 16, 17 serve to prevent current from passing through the winding. A higher voltage peak, however, opens the diodes and, in effect, short-circuits the winding 12, thus preventing the production of waves of excessive amplitude in the primary winding 11, which feeds the working relay. The maximum voltage to be passed is regulated by adjusting the resistances 15. A similar limiting arrangement is described for a Class-B amplifier (Fig. 3 not shown). The circuit shown in Fig. 5 is arranged to prevent the passage of current of less than a predetermined value. Two diodes 46, 47 are normally biased to open-circuit the transformer coupling 44, 45 between the amplifiers 42, 43 for weak currents, thereby cutting-out impulses produced by a toofeeble illumination of the photo-electric cell.
