Abstract: Methods and systems for forming crystallized products from solutions. Such a method includes depositing an input material in a solvent mixture comprising a solvent and an anti-solvent, increasing the temperature of the solvent mixture with the input material therein to an elevated temperature for a period of time sufficient to fully dissolve the input material in the solvent mixture to form a solution of the material, and performing a series of temperature cycles on the solution to produce a crystallized product from the material in the solution. The solution is alternated between heating cycles and cooling cycles based on the turbidity of the solution, and the solution is filtered to remove and collect the crystallized product therefrom.

Abstract: A method for traffic control in a cellular telephony system (100), each cell comprising at least one node, an RBS (130), for the control of traffic to and from users (150) in the cell. The traffic to each UE (150) can comprise at least one flow, and the method is intended for control of the flows in the traffic to UEs (150) in the system (100), and comprises one control function for each controlled flow to each of said UEs (150). Said control function comprises a congestion avoidance function (240, 440) which detects the presence or absence of congestion in a flow to an UE (150), and which, upon congestion or low utilization of the network reduces the bit rate to the UE (150) in a non-linear fashion, and which, in the absence of congestion, linearly increases the bit rate of the traffic to the UE (150).

Abstract: A method for linearizing voltage transmission through a transformer including a magnetic core and, input and output windings. A measurement signal is supplied to the input winding at a first frequency and an output signal is measured at the output winding of the transformer, wherein the voltage of the measurement signal may be so low that the transformer operates in a non-linear region. The method includes, for a conditioning signal, selecting a second frequency different from the first frequency, defining an amplitude value of the conditioning signal and supplying the conditioning signal to the input winding at the second frequency with the defined amplitude value so that the transformer operates in its linear region.

Abstract: A mechanism is provided to resolve the Iub transport network congestion efficiently for HSDPA by dynamic adjustment of the transmit window of the RLC. The RLC protocol is extended with congestion control functionality. The Iub TN and Uu congestion detection method in the Node-B signals the congestion to the RNC, and this congestion indication is used by RLC to react on the congestion situation. In the RNC, the transmission window of the RLC is adjusted to control the flow rate. When congestion is detected, the RLC transmission window size is decreased. When there is no congestion, then the RLC transmission window size is increased automatically. Different types of congestion are distinguished and are handled in different ways. Alternatively, congestion control is achieved without any modification in the RLC layer from the existing standard. Here, RLC STATUS PDUs are used to change the RLC transmission window size.

Abstract: The present invention is related to a method, base station (RBS) and computer program for quickly recovering from a detected congestion over the air interface. First the current bitrate at the which the air interface congestion has been detected is stored as a new reference bitrate. Thereafter, the base station (RBS) requests a reduction of the bitrate associated with the air interface. When the congestion condition has subsided the base station (RBS) requests a boost of the bitrate associated with the air interface up to the stored new reference bitrate. When finally the new reference bitrate has been reached, the base station (RBS) requests a linear increase of the bitrate associated with the air interface.

Abstract: The present invention proposes a solution in the area of HSDPA flow control. It proposes an improvement to transport network congestion detection and avoidance. The improvement proposes to use a measurement of incoming bitrate to determine the reduction of bitrate after a transport network congestion event. The advantage is that high bitrate reduction is only used when it is necessary; otherwise only small bitrate reduction is used, which results in small oscillation, and consequently higher transport network utilization.

The shaping rates of ongoing packet flows on said transport network are determined. And, based on said determined shaping rates of ongoing packet flows, an initial shaping rate for said new packet flow is selected so as to obtain a maximized fairness among all shaping rates.

Vanes (7, 8) are similar in shape to orange segments. Vanes (7, 8) are connected to opposing sides of and along the diameters of the central disc (6), and extend in mutually perpendicular planes, allowing for rotary movement.
