Abstract: A process for preparing poly-C2-C4-alkylene glycol mono(meth)acrylic acid esters by reacting (meth)acrylic anhydride with a poly-C2-C4-alkylene glycol carrying at least one OH group in the presence of abase having a solubility in the poly-C2-C4-alkylene glycol of not more than 10 g/l at 90° C.

Abstract: A method is suggested for the simultaneous personalization of several portable data carriers (2) respectively having at least one integrated circuit (6) for storing and/or processing information. According to the invention a unidirectional protocol serves for transmitting all identical personalization signal to several portable data carriers (2). These detect personalization data on thlis basis and store them in the integrated circuits (6), Preferably adapter elements (100; 101; 102) are used, which can accommodate at least one data carrier (50) and which are equipped with first interfaces (140; 150) for communicating with a reading device (20; 21; 22) and with second interfaces (120) for communicating with the accommodated data carrier (2). In a variant the portable data carriers (1) are transported in a transport device (600) which, at least temporarily, electrically contacts the contact area (9) of the portable data carriers (2) by means of a contacting unit (604).

Abstract: Aqueous dispersions comprising a polyurethane which comprises carbodiimide structural units of the formula (I) —N═C═N—  (I).

Abstract: A new approach to congestion control includes features which overcome many of the limitations of the current congestion control approaches. The new approach uses a rate-based congestion control mechanism which uses a combination of multiple indicators of congestion. The transmission rate is decreased when there is an indication of congestion and the rate is increased when there is an indication of little or no congestion. The approach can also limit the transmission rate of multiple data streams destined to the same network node.

Abstract: System, Device, And Method For Streaming A Multimedia File Encoded at a Variable Bitrate. The data is encoded at a variable bit rate and formed into packets having a server time stamp. The server time stamps are constructed so that the streaming of the packets will be substantially constant, not variable, and equal to a desired, budgeted bandwidth, such as one corresponding to fully utilizing a modem link. To schedule the sending of packets, the server uses the server time stamp, rather than, for example, the play-back time stamp. By having the data encoded at a variable bit rate, the otherwise-unused capacity, i.e., the capacity not used by the server, can be used to send packets needed in the future. This is accomplished by the server time stamps scheduling packets for transmission that will not be needed until the future.
