  • Patent number: 8837279
    Abstract: A technique for controlling data transmission over a connection employing congestion control is provided. The technique comprises two basic aspects: Detecting a decrease of Round Trip Time in respect of the connection, wherein the detection is facilitated by comparing a short-term Round Trip Time average with a long-term Round Trip Time average (302); and, in response to a result of the detection, adjusting the congestion control so as to increase the data transmission rate (304). Particularly, adjusting the congestion control includes enabling a data transmission rate that is (even) higher than what would have been allowed by any conventional, congestion control. In effect, the present technique may ‘push’ the conventional congestion control when it is not increasing the data transmission rate fast enough.

  • Publication number: 20130030183
    Abstract: The object of the present invention is a one-pot process for preparing the 2-acetoxy-5-(2-fluoro-?-cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-tieno[3,2-c]-pyridine (prasugrel) of the formula (I) by reacting the 5,6,7,7a-tetrahydro-4H-tieno[3,2-c]-pyridine-2-on of the formula (II) with 2-bromo-1-cyclopropyl-2-(2-fluorophenyl)-etanone of the formula (III) or with 2-chloro-1-cyclopropyl-2-(2-fluorphenyl)-etanone of the formula (IIIa) and acetylating of the formed compound of the formula (IV), wherein the reaction is carried out in the presence of an organic base with an acetylation agent without isolating the compound of the formula (IV). The coupling and acetylation are carried out in the presence of the same organic base such as triethylamine, N,N-diisopropyl-ethylamine or pyridine. At the end of the process the prasugrel of the formula (I) is purified by recrystallization from an organic solvent or a mixture of solvents.

  • Patent number: 8205600
    Abstract: An apparatus for the production of ozone for an internal combustion engine comprising a non-conductive shell having a first and second opening which allows air to flow therethrough and first and second electrodes disposed inside the shell. The first electrode is spaced a distance from the second electrode, the first electrode having a smaller diameter than, and being aligned axially within the second electrode. The first electrode permits air to flow therethrough. A high voltage source is connected to the first and second electrode, the high voltage source capable of producing a voltage differential on the first and second electrodes sufficient to cause the production of ozone. A change from oxygen to ozone occurs in the air flowing through the apparatus. The shell is preferably cylindrical.

  • Patent number: 8170557
    Abstract: A method of reducing buffer overflow in a cellular radio network caused by a transfer of data from a buffer in a first cell to a buffer in a second cell when a handover of mobile equipment from said first cell to said second cell occurs. The method comprises temporarily increasing an amount of temporary buffer space required to handle data transferred from the buffer of the first cell to the buffer of the second cell. In one embodiment of the method, prior to increasing the amount of temporary buffer space, the amount of temporary buffer space required is calculated.

  • Patent number: 8000237
    Abstract: A throttle device is coupled with a central processing unit in a node for reducing traffic overload in a Next Generation Network (NGN). The device is coupled with a basic throttle with different levels of traffic priority and both are situated between a source node and a target node for processing traffic. When a traffic offer is received by the throttle, the throttle device by provisionally updating the basic throttle priority levels, determines whether to send the traffic offer on to the source node. If the provisional, traffic priority level is greater than a new traffic priority level the traffic is admitted and rejected if the updated priority level is less than the new traffic priority level.

  • Patent number: 7965629
    Abstract: A system, method and node for overload control in a network.
