Title: A routing procedure for multicast communication which evaluates utility functions to find the optimum combination of routes
Inventor: HIIE MAGNUS
IPC: H04L45/122
Filed: 2009-04-14
Abstract: The invention deals with the routing of a data stream from a source node to a plurality of end-nodes via relaying nodes. The aim of the invention is to find the optimum combination of routes. This is achieved by evaluating a utility function for each possible route between the source node and each end node, using the evaluated utility functions to obtain an overall utility value for each of the route combinations which link the source node to each of the end-nodes, and then comparing the overall utility values. The utility function is route-dependant and defines a quantitative measure of the end-user benefit that would be experienced at a respective end-node, e.g. by actually displaying a video stream to the user. Factors which affect utility may include transport bitrate, packet loss rate, delays, receiver video window size etc (see pages 25-27). The invention finds particular application in peer-to-peer (p2p) systems. The optimisation procedure may be carried out using a plurality of distributed optimisation nodes - see GB0906410.6.

Inventor: LAASIK MAREK
IPC: G06F21/33
Filed: 2009-05-13
Abstract: Disclosed is a method of enabling a feature on a user's terminal, that is required to process received data. The method starts by determining that a user's terminal requires the use of a feature, that is otherwise not enabled, for processing data during a communication event. Next, a certificate is retrieved enabling the use of the feature at the user terminal and the feature is used to process the sent data. The user's terminal may request the certificate from a node on the network, the node determining, based on the request, whether the use of the feature at the terminal is authorized and if so sending the certificate. The certificate may include a signature authenticating the certificate, an identifier of the feature to be enabled, the user, the terminal and parameters relating to the feature. The feature may be permanently or temporarily enabled. The feature may be codec, a multiparty video session or a screen sharing session.

Title: Improvements relating to telephone systems
IPC: H04Q1/446
Filed: 1941-08-08
Abstract: 550,344. Automatic exchange systems. SIEMENS BROS., & CO., Ltd., and CLAY, D. L. Aug. 8, 1941, No. 10110. [Class 40 (iv)] It is usual when impulses are repeated over junctions for the arrival at the repeater of the first impulse of each train to bring about a circuit change which improves the condition of the outgoing circuit as regards impulsing. According to the invention, this change is effected by a prefix signal which precedes each impulse train. The prefix may talk the form of an unbalancing of the loop or of a very short break which can be detected by a high-speed relay. When voice-frequency impulsing is employed, the prefix may serve to connect up a receiver in readiness for the reception of impulses. The repeater shown in Fig. 1 generates and transmits a prefix before each impulse train whether it receives a prefix or not, a delay being imposed on the repeated impulses in the latter case. Upon seizure, line relay AT connects up AB, AC and release relay B connects up HA to complete the outgoing loop through relay D. If a prefix, which consists of a brief earth connection to one wire of the loop, is received, differential relay AS responds and relays PS, PT energize in succession to repeat the signal. Relays CO, COA, COB also energize in succession, transferring the incoming loop to relay AA and putting the outgoing loop under the direct control of that relay for the repetition of impulses. The continu- - ance of this condition is dependent on the operation of dialling relay C, so that at the end of the train the circuits are restored to their condition before the prefix was received. If no prefix is received, the relapse of AT at the first impulse, besides connecting up dialling relay U, causes the successive operation of PS, PT to send the prefix. The control of the outgoing loop through relays AB, AC in this case delays the repeated impulses to allow for 'the insertion of the prefix. Relays PS, PT, restore at the end of the train. The modification shown in Fig. 2 employs two single-winding line relays, AST being released by a prefix while AT is held. Relay CO is disconnected by PT to prevent its being flicked during the impulsing when no prefix is received. It is to be noted that the prefix produces no 'effect at an incoming selector which has only the usual .two-winding line relay. In the repeater shown in Fig. 4, in 'which the repeated impulses are of voice-frequency, the receipt of the prefix causes the successive operation of relays PS, PU, PT, with the result that the outgoing loop is bridged through resistance R and a prefix is sent until relay AA energizes, this relay being connected to the incoming loop, as in Fig. 1, for the repetition of impulses. In a modification, Fig. 3 (not shown), the repeater receives a prefix but does not transmit one.

Filed: 1950-04-26
Abstract: 670,406. Refrigerating. PHILLIPS, H. A. April 26, 1950 [June 23, 1949], No. 10266/50. Class 29 An accumulator drum 20 in the suction line 10 collects unevaporated refrigerant and supplies it to a trap 26 from which it is forced by high pressure refrigerant gas to a second trap 28 at a higher level. From the second trap the liquid refrigerant is forced back to the high pressure side of the system, e.g. to the condenser-receiver 17. The liquid refrigerant drains from the accumulator 20 through a check valve 25 to the lower trap 26 and when the liquid reaches a float switch 44 a solenoid valve 40 is opened to supply high pressure gas from a pipe 34, connected to the high pressure line 15, to a three-way valve 33, moving this valve to close an outlet pipe- 35 and open a connection 32 to the lower trap. The pressure closes the check valve 25 and the liquid in the trap is forced up a pipe 30 to the upper trap 28. When the liquid in the lower trap falls to the level of a float switch 43 the solenoid valve 40 is closed and the three-way valve 33 closes the inlet pipe 34 and opens the outlet 35 which vents the trap to the suction line 10. The upper trap 28 is identical to the trap 26 having inlet and outlet connections 51, 54 with the high pressure line 15 and. suetino line 10, and a solenoid valve 57 operated by float switches 60, 61. When the trap is full the liquid is forced by the high pressure gas through a pipe 45 and check valve 46 to the receiver 17. Specification 662,563 is referred to.

Abstract: 1491844 Devices for folding stacks of sheet-like articles F ATTUCCI 16 March 1976 [20 March 1975] 10380/76 Heading B8C A device for folding a stack 5 of sheet-like articles, e.g. flattened bags, comprises a conveyer having spaced, parallel conveyer belts 4 arranged to carry a stack of sheet-like articles, at least one grid, 8 or 9, composed of parallel rods, and stop means 6 engageable by a stack on the conveyer, the grid 8 or 9 being angularly movable from a position below the working surface of the conveyer to fold a stack positioned on the conveyer in engagement with the stop means 6. Individual tubular thermoplastic bags 3, sheared and welded at 1A, are discharged from a machine 1 in flattened form on to the conveyer 4 to form a stack 5 thereon while the conveyer is stationary, the conveyer comprising a number of transversely-spaced endless belts. Several stacks of bags may be formed side-by-side, and the stacks may be formed on the conveyer by other means such as guide surfaces and jaws for gripping and orientating the bags. When a stack has been formed, the conveyer indexes forward until the stack is located over a supporting surface 10 and abuts the stop 6, which comprises a pivotally-mounted grid of rods 7, The stack is folded by rotating the first grid 8 clockwise to a position B8 to form a first fold and then pivoting the grid 8 in the opposite sense into an upright position C8 to act as a stop while grid 9 is rotated anticlockwise to position E9. A labelling machine 11 is then lowered as shown in Fig. 7 for a pressing cylinder 13 to apply a self-adhesive label 14 to the stack and maintain it in its twice-folded state. The folded grids 8, 9 are then returned to their positions below the conveyer 4, the labelling machine 11 is raised, and the stop 6 is pivoted upwardly as the conveyer is indexed forward again to advance the folded stack to a collector (16), Fig. 10, not shown, or to a further conveyer, and to transport the succeeding stack towards the stop 6. The height of the grids 8, 9 above the working surface of the conveyer 4 in the positions B8, E9 and their horizontal spacing, and the size, and position, of the supporting surface 10 can be varied in accordance with the thickness of the stack, the dimensions of the bags, and the required positions of the folds. In a modification, Figs. 12, 16, not shown, the stack is folded only once on the conveyer (4) and is then transported by a transversely arranged second conveyer (22) to a second gate (26) where the stack is supported on a surface (31) and folded again while in abutment with a raised grid (33). A labelling machine (34) delivers a self-adhesive label 36 to the folded stack, Fig. 23, to maintain it in its folded state. In a further modification, Figs. 17-21, not shown, the stack is folded and labelled on the conveyer (4), in the form shown in Fig. 24. The folded stack may be delivered to a packing machine, e.g. to pack one, or more, stacks into an envelope, sack, box or other wrapper.
