    • A hydraulic system includes a hydraulic pump, a reservoir, a hydraulic function, such as a cylinder, and a power beyond valve for controlling communication between the pump, the reservoir and the cylinder. The pump provides pressurized fluid at a pump output as a function of the pressure in a load sensing port. For generating a pump controlling load sensing signal in case that the cylinder does not generate such a signal, it is proposed to provide a valve which blocks in a first position or opens in a second position communication between the feed line of the cylinder and the load sensing port of the pump. The valve functions in dependence of control pressures acting on each side of a valve member. A spring is provided biased to urge the valve member to its first closed position. Further, shift valve means are provided to supply selectively different pressures to both sides of the valve member. In an open-center hydraulic system, the valve means the shift valve means connects the first side of the valve member to the reservoir and the second side of the valve member to the feed line. In a closed-center system, the shift valve means will be changed over to connect the first side of the valve member to the feed line and the second side of the valve member to the pump outlet.
    • 液压系统包括液压泵,储存器,诸如气缸的液压功能,以及用于控制泵,储存器和气缸之间的连通的阀。 泵在泵输出处提供加压流体作为负载感测端口中的压力的​​函数。 为了在气缸不产生这样的信号的情况下产生泵控制负载感测信号,建议提供在第一位置或第二位置处打开的阀,该气门在气缸的进给管线和负载之间连通 检测泵的端口。 该阀根据作用在阀构件的每一侧上的控制压力而起作用。 偏压的弹簧设置成将阀构件推到其第一关闭位置。 此外,提供换档阀装置以向阀构件的两侧选择性地供应不同的压力。 在开放中心液压系统中,阀意味着换档阀装置将阀构件的第一侧连接到储存器,将阀构件的第二侧连接到进给管线。 在闭合中心系统中,换档阀装置将被切换以将阀构件的第一侧连接到进料管线,将阀构件的第二侧连接到泵出口。

    • A method for detecting a service prevention attack on a first communication terminal, wherein the detection of the service prevention attack is performed by the first communication terminal. The first and at least one second communication terminal comprise communication subscribers in a communication network. The communication connection is provided between the first and the second communication terminals. If the first communication terminal does not receive a status inquiry message of the second communication terminal in a timely manner, receipt of at least one further message indicating that the sender is the second communication terminal is interpreted as a service prevention attack on the first communication terminal and an action is taken, such as all or a plurality of packets are deleted from the input buffer memory or the connection between the two communication terminals is terminated.
    • 一种用于检测第一通信终端的服务防范攻击的方法,其中,所述服务防范攻击的检测由所述第一通信终端执行。 第一和至少一个第二通信终端包括通信网络中的通信用户。 通信连接设置在第一和第二通信终端之间。 如果第一通信终端没有及时地接收到第二通信终端的状态询问消息,则将指示发送者是第二通信终端的至少一个其他消息的接收解释为对第一通信终端的服务防范攻击 并且采取动作,诸如从输入缓冲存储器中删除所有或多个分组,或者终止两个通信终端之间的连接。

    • In a semiconductor laser, at least one temperature sensor is disposed directly on or integrated in a semiconductor laser chip for measuring an operating temperature. Precisely and/or locally solved measurement of the operating temperature of the laser are possible. One or more temperature sensors may be placed and fastened directly onto the laser chip or in a hole of the laser chip by welding, especially with Nd-YAG-laser light or light with similar characteristics. Fine equalization of temperature may be carried out, for example, by Peltier elements, components of the Peltier elements being mounted directly onto the laser chip. A cascaded arrangement of thermoelements and Peltier elements on a laser chip is also provided for.
