摘要： Fuel cell device (10) comprising a fuel cell assembly (5) with at least one polymer electrolyte membrane fuel cell and a fuel delivery means for providing a fuel flow. The device is provided with means (4) for pre burning adapted to burn fuel entering the fuel cell assembly during the start up phase until the fuel flow is increased to a predetermined level and/ or the oxygen concentration is decreased to a predetermined level. The method of operating a fuel cell device (10), the fuel cell device comprising a fuel cell assembly (5) with at least one polymer electrolyte membrane fuel cell, a fuel delivery means for providing a fuel flow. The method comprises the steps of initiating the start up phase by causing the fuel delivery means to deliver a fuel flow, whereby a means (4) for pre burning burns off fuel entering the fuel cell assembly, monitoring the fuel flow and /or the oxygen concentration and when the fuel flow is increased to a predetermined level and/ or the oxygen concentration is decreased to a predetermined level, switching from start up phase to power generating phase.

摘要： Methods and apparatus for securely streaming multimedia packets, such as RTP packets, are disclosed, in which the payloads of the packets are shuffled. This reordering is performed using a shuffling function that depends on sequence numbers associated with each of the packets, a predetermined group size N , and a predetermined initialization value; in some embodiments this shuffling function comprises a cryptographic hashing function or other one-way function. A receiving device may reverse the shuffling, using a similar shuffling function, if the predetermined group size N and the predetermined initialization value are known.
摘要翻译：公开了用于安全地流式传输诸如RTP分组的多媒体分组的方法和装置，其中分组的有效载荷被混洗。使用依赖于与每个分组相关联的序列号，预定的组大小N和预定的初始化值的混洗功能来执行该重新排序; 在一些实施例中，该混洗功能包括密码散列函数或其他单向函数。如果预定的组大小N和预定的初始化值已知，则接收装置可以使用类似的混洗功能来反转混洗。
