    • The present invention provides a method for binding a (smart) secure device (2) to a wireless phone, said wireless phone comprising an identifier parameter, said secure device (2) being adapted to communicate with an Over-The-Air (OTA) server and being suitable for receiving services from a network operator in an authorised area determined with localisation parameters stored in the OTA server, wherein the method comprises the following steps : a. storing the identifier parameter of the wireless phone into the secure device (2) at a first powering on of the wireless phone; b. requesting a user registration on the OTA server so as to download the localisation parameters from the OTA server into the secure device (2). After successful registration confirmation from OTA server, for each powering on, the secure device (2) compares the above two parameters in the secure device (2) with the values from the phone, if they are not the same, authentication is forbidden.

    • A circuit for determining an angular direction of an acoustic cource relative to a reference direction comprises a uni-directional microphone (12), a omni-directional microphone (20), and a background noise suppression circuit (11). The uni-directional microphone (12) is a directional microphone such that the intensity of an acoustic source detected at the uni-directional microphone (12) is dependent on the angular direction of the acoustic source relative to a reference direction (30). The omni-directional microphone (20) is a non-directional microphone such that the intensity of the acoustic source detected at the omni-directional microphone (20) is substantially indenpendent of the angular direction of the acoustic source relative to the reference direction. The background noise suppression circuit (11) determines the direction of the acoustic source by calculating a quotient between a signal strength characteristics (21) and (31) of the acoustic source as detected by the two microphones (12) and (20) and provides for suppressing an output signal (17) if the quotient does not indicate that the acoustic source that is within a threshold angle of the reference direction (30).
    • 用于确定声源相对于参考方向的角度方向的电路包括单向麦克风(12),全向麦克风(20)和背景噪声抑制电路(11)。 单向麦克风(12)是定向麦克风,使得在单向麦克风(12)处检测到的声源的强度取决于声源相对于参考方向(30)的角度方向。 全向麦克风(20)是非定向麦克风,使得在全向麦克风(20)处检测到的声源的强度基本上与声源相对于参考方向的角度方向是独立的。 背景噪声抑制电路(11)通过计算由两个麦克风(12)和(20)检测到的声源的信号强度特性(21)和(31)之间的商,来确定声源的方向,并且提供 用于抑制输出信号(17),如果商不指示声源在参考方向(30)的阈值角内。
