    • In general, this disclosure describes a technique to simulate the keystrokes on some handset device like remote controller, keyboard, to the touch-based event like slide, tab on the current scene in order to manage the applications and operating systems which are originally designed around the touch interface, with the help of scene recognition algorithm. To realize this simulation, the information for touch-based events and characteristic measurement should be acquired from the scenes of application which have been collected previously. Then, if a scene of the application is recognized with the characteristic information, the layout of the touch-based events in the scene is sure to be known, and consequently the operation of handset device can be mapped to the touch-based events. For instance, if a scene with four buttons is identified, the 'up' keystrokes can be translated to the event of touching the point located above the current scene.
    • 通常,本公开描述了一种技术来模拟一些手持机设备上的按键,如遥控器,键盘,到当前场景上的基于触摸的事件,如幻灯片,标签,以便管理最初设计的应用和操作系统 触摸界面,借助场景识别算法。 为了实现这种仿真,触摸事件和特征测量的信息应该从以前收集的应用场景中获取。 然后,如果利用特征信息识别应用的场景,则确定场景中的基于触摸的事件的布局是已知的,并且因此可以将手持通话器设备的操作映射到基于触摸的事件。 例如,如果识别出具有四个按钮的场景,则可以将“向上”按键转换为触摸位于当前场景上方的点的事件。

    • A dynamic dual-port passive intermodulation reference signal generator for calibrating an intermodulation testing device, mainly comprising: a power allocation coupling network, a non-linear device that may be located under a biasing condition, and a voltage modulation module. Extraction of a carrier signal is performed through a power distribution coupling network; the carrier signal as extracted excites a non-linear device to generate an intermodulation signal; this part of signal, together with the excitation signal, is coupled back to two ports of the generator by the same power distribution coupling network, thereby forming reflected and transmitted reference intermodulation levels as reference sources for calibrating the intermodulation testing apparatus. The voltage modulation generating module may generate a voltage wave of a certain value, implementing modulation of the intermodulation signal; through the modulated intermodulation signal, the intermodulation testing region power level and intermodulation transient response feature within a nominal range are calibrated for the intermodulation testing device.
