    • An electromagnetic test system induces large current pulses in a component of a system under test. The pulse waveform may be selectively varied, and possible waveforms include square wave pulse, double exponential, and damped sinusoid waveforms. In a preferred embodiment, these waveforms are generated by simultaneously triggering a plurality of modular signal injector units having ferrite cores hinged to permit positioning of a system component under test (such as a cable or antenna) along their central axes without disturbing connections of the tested component within its system. The injector units are resonance tuned to induce a particular signal in the component under test when triggered, and the modular construction of the system permits selective connection of different injector units to provide different desired total induced signals.
    • 电磁测试系统在被测系统的一个部件中引起大电流脉冲。 可以选择性地改变脉冲波形,并且可能的波形包括方波脉冲,双指数和阻尼正弦波形。 在优选实施例中,这些波形是通过同时触发多个具有铁氧体磁芯的模块化信号注射器单元来产生的,所述模块化信号注射器单元铰接成允许沿着其中心轴定位待测系统组件(例如电缆或天线),而不干扰所测试的连接 其系统内的组件。 喷射器单元被谐振调谐以在触发时在待测部件中感应特定信号,并且系统的模块化构造允许不同喷射器单元的选择性连接以提供不同的期望的总感应信号。

    • The computer pointing input device allows a user to determine the position of a cursor on a computer display. The position of the input device in relation to the display controls the position of the cursor, so that when a user points directly at the display, the cursor appears at the intersection of the display and the line of sight from of the input device. When the device is moved, the cursor appears to move on the display in exact relation to the input device. In addition, a cursor command unit allows the user to virtually operate the input device wherein changes in the position of the device allow the user to spatially invoke mouse functions. The computer pointing input device is designed to operate with a computer having a processor through a computer communication device.
    • 计算机指向输入装置允许用户确定光标在计算机显示器上的位置。 输入设备相对于显示器的位置控制光标的位置,使得当用户直接指向显示器时,光标出现在来自输入设备的显示器和视线的交点处。 当设备移动时,光标似乎在与输入设备完全相关的显示屏上移动。 此外,光标命令单元允许用户虚拟地操作输入设备,其中设备位置的改变允许用户在空间上调用鼠标功能。 计算机指向输入设备被设计成通过计算机通信设备与具有处理器的计算机一起操作。
