Title: Real-time VoIP transmission quality predictor and quality-driven de jitter buffer
Inventor: NARBUTT MIROSLAW ANDRZEJ
IPC: H04L12/24
Filed: 2009-12-14
Abstract: A VoIP quality predictor working in real-time is introduced. This predictor provides feedback regarding impairments, quality and user satisfaction to quality enhancement mechanisms. Quality enhancement mechanisms use this information to tune their control parameters. Additionally, a quality-driven de-jitter buffer is introduced. This buffer has a number of pre-determined outputs. The transmission quality predictor calculates the transmission rating factor.Information regarding voice codec and packet loss is determined from packet headers. Delay information is determined from a time stamp that is inserted into each RTP packet header by the sender and extracted at the receiver. Finally, the play-out delay of received VoIP packets for the actual time window is set equal to the play-out buffer output in the prior time window with the highest R-factor. With quality-driven de-jitter buffering the quality of VoIP is maximized as well as end-user satisfaction.

Title: Electrically controlled apparatus for producing alternating pressure in a cylinder with an operation period
IPC: H01H33/32
Filed: 1937-04-09
Abstract: 487,530. Fluid - pressure brakes. KNORR - BREMSE AKT.-GES. April 9, 1937, No. 10193. Convention date, April 30, 1936. [Class 103 (i)] [Also in Groups XXVIII and XXII] An electrically controlled apparatus for producing variable pressures during a working period in a cylinder 11, used e.g. in applying brakes, comprises a controlling valve actuated with a step-by-step motion controlled by a switch 13 under the influence of the cylinder pressure so that the pressure fluid during one period passes through a check valve 4 and a pressure reducing valve 9 and, after this is closed by the rising cylinder pressure, through an adjustable throttle valve 10 to the cylinder. A relatively high cylinder pressure is thus attained which opens the relief valve, reducing the cylinder pressure to a value at which the switch 13 is again closed giving the valve 3 a further step. The fluid then passes through an accumulator 6 and an adjustable overflow valve and again through the valves 9, 10 which in this period do not determine the pressure. The relief valve 12 is opened when the electromagnet 14 is not excited.
