    • A system and method for collecting data on small-arms usage in the form of a device which is mounted to the firearm so as to be able to sense at least an impulse in the firearm due to firing. The device is mounted to the gun so as to detect impulses due to firing. A processor accepts impulse signals from the sensor, and uses either a hold-off delay or a windowing time to determine and store information related to the firing of the firearm. This information may be any combination of temperature, firing rate, firing intervals and time data for subsequent analysis, and, optionally, information identifying the weapon to which the device is attached. The device preferably has an interface to transfer data from the device to a computer or other data collection device.
    • 一种用于以装置形式收集关于小型武器使用的数据的系统和方法,所述装置安装在枪支上,以便能够至少感测由于射击而在枪支中的脉冲。 该装置安装到枪上以便检测由于点火而产生的脉冲。 处理器接收来自传感器的脉冲信号,并使用延迟延迟或窗口时间来确定和存储与火器射击有关的信息。 该信息可以是用于后续分析的温度,燃烧速率,燃烧间隔和时间数据的任何组合,以及可选地,识别装置所附着的武器的信息。 该设备优选地具有将数据从设备传送到计算机或其他数据收集设备的接口。

    • A flip-chip module is interconnected to a PCB or circuit card through a peripheral LGA interposer connector. The flip-chip is mounted on the same surface of the module substrate as the peripheral array of LGA interconnection pads and projects into a central opening of the interposer. An opening in the upper stiffener of the PCB or circuit card permits the peripheral array of LGA interconnection pads to make contact with corresponding LGA PCB or circuit card pads. A first heat sink is arranged to thermally contact the entire surface of the substrate opposing the surface upon which the flip-chip is mounted. An opening in the PCB or circuit card and lower stiffener allows a second heat sink to make thermal contact with the surface of the flip-chip.
    • 倒装芯片模块通过外围LGA插入器连接器与PCB或电路卡互连。 倒装芯片安装在模块基板的与LGA互连焊盘的外围阵列相同的表面上并投影到插入器的中心开口中。 PCB或电路卡的上加强件中的开口允许LGA互连焊盘的外围阵列与相应的LGA PCB或电路卡焊盘接触。 布置第一散热器以使与基板相反的表面的整个表面热接触,所述表面上安装有倒装芯片。 PCB或电路卡和下加强件中的开口允许第二散热器与倒装芯片的表面进行热接触。
