    • The disclosure discloses a method for processing/testing of a called terminal and a Long Time Evolution (LTE) system. The method comprises that: a network side of the LTE system sends a paging message to the terminal residing in an LTE cell which is called by a Circuit Switched (CS) domain service; the terminal establishes a Radio Resource Control (RRC) connection with the network side; the terminal sends to the network side a message for requesting to establish a CS domain service; the network side indicates, to the terminal, carrier frequency information of a Global System for Mobile Communications (GSM) cell to which the terminal needs to be redirected; the terminal sends a channel request message to the GSM cell; the terminal performs routing area updating in the GSM cell; the terminal sends a paging response message to the GSM cell; the terminal establishes the CS domain service in the GSM cell. By using the disclosure, when being called by the CS domain service, the terminal residing in the LTE cell can return to a cell of a corresponding network to establish the CS domain service.
    • 本公开公开了一种用于处理/测试被叫终端和长时间演进(LTE)系统的方法。 该方法包括:LTE系统的网络侧向驻留在通过电路交换(CS)域服务调用的LTE小区的终端发送寻呼消息; 终端与网络侧建立无线资源控制(RRC)连接; 终端向网络侧发送请求建立CS域服务的消息; 网络侧向终端指示终端需要被重定向到的全球移动通信系统(GSM)小区的载波频率信息; 终端向GSM小区发送信道请求消息; 终端在GSM小区中执行路由区域更新; 终端向GSM小区发送寻呼响应消息; 该终端在GSM小区中建立CS域服务。 通过使用本公开,当被CS域服务调用时,驻留在LTE小区中的终端可以返回到相应网络的小区以建立CS域服务。

    • A system includes multiple speakers arranged in a speaker array configuration. The system also includes one or more filters configured to filter audio signals and generate filtered audio signals. The one or more filters are configured to operate using filter coefficients associated with a desired beam pattern to be produced by the multiple speakers. The system further includes at least one amplifier configured to amplify the filtered audio signals and provide the amplified filtered audio signals to the speakers. The one or more filters reside within or are coupled to the at least one amplifier. The system may further include a controller configured to modify at least one of the filter coefficients based on a change in the speaker configuration. The filters may operate independently of a centralized processor, and a centralized processor may not even be required to provide electronic beam forming.
    • 系统包括布置在扬声器阵列配置中的多个扬声器。 该系统还包括被配置为过滤音频信号并产生滤波后的音频信号的一个或多个滤波器。 一个或多个滤波器被配置为使用与由多个扬声器产生的期望波束图案相关联的滤波器系数进行操作。 该系统还包括至少一个放大器,其被配置为放大经滤波的音频信号并将放大的经滤波的音频信号提供给扬声器。 一个或多个滤波器驻留在或耦合到至少一个放大器。 该系统还可以包括控制器,其被配置为基于扬声器配置的变化来修改至少一个滤波器系数。 滤波器可以独立于集中处理器操作,并且中央处理器甚至可能不需要提供电子束形成。

    • A rotational micro-actuator (20) used in hard disk driver is disclosed. It comprises a frame (21) approximately in the shape of letter “S” and PZT pieces (28, 29) attached to said frame (21), wherein said frame (21) is formed with a central coupling portion (213) by which the micro-actuator (20) is coupled to a suspension tongue (177), and two pieces of said PZT (28, 29) are arranged in central symmetry manner about said central coupling portion (213) such that said micro-actuator (20) can rotate about said central coupling portion (213) in response to the driving signals applied to said PZT pieces (28, 29), thus cause the displacement of the head element secured to the micro-actuator (20) so as to achieve the fine positioning of the head element. With above configuration, the micro-actuator of this invention will not cause the resonance of the suspension base plate during operation. Thereby the servo bandwidth of the hard disk driver is expanded.
    • 公开了一种用于硬盘驱动器的旋转微致动器(20)。 它包括大致为字母“S”的框架(21)和附着到所述框架(21)上的PZT片(28,29),其中所述框架(21)形成有中心联接部分(213) 微致动器(20)联接到悬挂舌(177),并且两个所述PZT(28,29)围绕所述中心联接部分(213)以中心对称的方式布置,使得所述微致动器(20) )可以响应于施加到所述PZT片(28,29)的驱动信号而围绕所述中心联接部分(213)旋转,从而导致固定到微致动器(20)的头元件的位移,以便实现 头元素的精细定位。 通过上述结构,本发明的微型致动器在操作中不会引起悬架基板的共振。 从而扩大了硬盘驱动器的伺服带宽。
