    摘要： Method for executing applications on electronic devices, wherein a first application (11) on a first electronic device (21) controls the execution of a second application (12) on a second electronic device (22), and a first server (31) provides an environment for executing the second application (12), wherein the method includes the steps of: executing the first application (11) on the first electronic device (21); initiating the execution of the second application (12) by the first electronic device; coupling of the first electronic device (21) to the second electronic device (22); providing the environment for executing the second application (22) by the first server (31); and executing the second application (12) on the second electronic device (22).

    摘要： A method for transmitting messages from a server to a client in an internet transmission system includes: (a) the client sends to the server a request for transmitting a picture file, (b) in response to the reception of the request the server generates a picture file with a first content, in case that no message is available for the client, and delays the transmission of the picture file to the client for a time interval, (c) in response to the reception of the picture file with the first content, the client again sends a request for sending (transmitting) a picture file, (d) the steps (a) to (c) are repeated till, upon the last request, a message is available at the server for transmission to the client, (e) the server transmits, in response to the last request of the client, the picture file with a second content, (f) in response to the reception of the picture file with the second content, the client then sends a request for transmitting the message, (g) in response to the reception of the request for transmitting the message, the server then transmits the message to the client.

    摘要翻译： 本发明涉及一种用于在互联网传输系统（104）中从服务器（102）向客户端（100）传输消息的方法。 该方法包含以下步骤：a。 客户端向服务器发送传输图片文件（200）的请求，b。 响应于该请求的接收，在没有消息可用于客户端的情况下，服务器生成具有第一内容的图片文件，并且延迟图片文件到客户端的传输一段时间间隔（202,204,205） 208），c。 响应于接收到具有第一内容的图片文件，客户端再次发送发送（发送）图片文件（210,212,216）的请求，d。 重复步骤（a）到（c），直到最后一次请求时，在服务器处有消息传送给客户机（202），例如， 响应于客户端的最后请求，服务器传送具有第二内容的图片文件（206），f。 响应于接收到具有第二内容的图片文件，客户端然后发送用于发送消息的请求（212,214），g。 响应于接收到发送消息的请求，服务器然后将消息发送给客户端（216）。 （图1,2）本发明还涉及用于执行该方法的客户端（图4）和服务器（图5）。 通过这种方法，实现了解释器，特别是Javascript解释器不被阻塞，加载图片不阻止加载另一图片，绕过SOP（相同原点策略）的安全限制，服务器之间的通信负载 客户端减少，从而降低能耗，提高盈利能力，同时提高服务器与客户端之间的通信速度。

    摘要： In order to realize a correction for changes in the reproduction loudness at low frequencies in a downmix-arrangement, a mixing arrangement is proposed for mixing at least two audio signals, which mixing arrangement is provided with - a first unit (104) for deriving a first power signal, which is a measure for the power of the first audio signal, - a second unit (105) for deriving a second power signal, which is a measure for the power of the second audio signal, - a cross-correlation unit (103) for deriving a cross-correlation signal, which is a measure for a cross-correlation between the first and the second audio signal, - a unit (106) for deriving multiplication parameters from the first and second power signals and the cross-correlation signal, and - a multiplication and combination unit (107) for carrying out a signal processing on the first and second audio signals and combining them. The unit (106) for deriving the multiplication parameters is provided with a combination unit (110) for deriving a combination signal which is a measure for a combination of the first and second power signals and the cross-correlation signal, and is provided with a scaling unit (109) for scaling one of the signals in the unit for deriving the multiplication parameters with a scaling signal. The scaling signal (D[k]) has a frequency characteristic which is a substantially constant below a first frequency value (k
    L ), is increasing between the first frequency value (k
    L ) and a second higher frequency value (k
    U ) and is again substantially constant above the second frequency value. The unit (106) for deriving the multiplication parameters is further adapted to derive a single multiplication parameter m[k]) from the combination signal, and the multiplications and combination unit (107) is adapted to carry out a signal processing on the first and second audio signals which is equivalent to - multiplying the first and second audio signals with this single multiplication parameter, and - combining the so multiplied first and second audio signals.
