    • The system, in a preferred embodiment, comprises a transmitter, receiver and processor connected to the receiver. The transmitter is arranged to transmit a signal through a medium, the signal comprising a plurality of different frequency components and transmission technologies. The receiver is arranged to receive the signal following propagation through the medium. The processor is arranged to generate, at a first time, one or more transfer functions from the received signal, each transfer function defining values for a predetermined signal parameter at different frequencies. The processor then generates, at a second time, one or more further transfer functions from the received signal and compares a transfer function with the further transfer function for the same signal parameter. An output is generated if the difference between the transfer function and the further transfer function exceeds a preset threshold.
    • 在优选实施例中,该系统包括连接到接收器的发射器,接收器和处理器。 发射器被布置成通过介质传输信号,该信号包括多个不同的频率分量和传输技术。 接收器被布置成在通过介质传播之后接收信号。 处理器被布置为在第一时间从接收的信号生成一个或多个传送函数,每个传递函数定义不同频率的预定信号参数的值。 然后处理器在第二时间从接收到的信号产生一个或多个另外的传递函数,并将传递函数与用于相同信号参数的另外的传递函数进行比较。 如果传递函数和另外的传递函数之间的差超过预设的阈值,则产生一个输出。

    • The invention relates to a method of operating a network of a plurality of communication apparatuses (1, 2, 5 to 8) and particularly to a method of operating an ad hoc network between Bluetooth apparatuses. A token (3, 9 to 12, 15), in which the apparatus address of the associated apparatus is stored, is assigned to a plurality of communication apparatuses (1, 2, 5 to 8). At least one communication apparatus is used as a token read apparatus (4, 13 and 14) so as to read the apparatus address of a first communication apparatus (1), stored in the token (3, 9 to 12, 15). The token read apparatus (4, 13 and 14) builds up a connection with the first communication apparatus (1) by means of the apparatus address, and/or the apparatus address is transmitted by the token read apparatus (4, 13 and 14) to at least a second communication apparatus (2). The second communication apparatus (2) can then build up a connection with the first communication apparatus (1).
    • 本发明涉及一种操作多个通信设备(1,2,5至8)的网络的方法,特别涉及一种在蓝牙设备之间操作自组织网络的方法。 将存储有相关装置的装置地址的令牌(3,9〜12,15)分配给多个通信装置(1,2,5〜8)。 至少一个通信装置用作令牌读取装置(4,13和14),以便读取存储在令牌(3,9到12,15)中的第一通信装置(1)的装置地址。 令牌读取装置(4,13和14)通过装置地址建立与第一通信装置(1)的连接,和/或由令牌读取装置(4,13和14)发送装置地址, 至少第二通信设备(2)。 第二通信装置(2)然后可以建立与第一通信装置(1)的连接。
