    • Two detector elements are optically isolated by having them mounted (die-attached) on the same header so that the thermal tracking of the detectors respectively for the signal and reference channels is close to ideal. Furthermore, such an optical isolation technique or cross-interference suppression between the two detector elements mounted on the same header also allows the use of only one and the same narrow band pass interference filter covering both detectors. Thus the thermal tracking of the filters respectively for the signal and reference channels is also close to perfection as both channels share the same filter.
    • 两个检测器元件通过将它们安装在(相连)在相同的头上而被光学隔离,使得分别用于信号和参考通道的检测器的热跟踪接近理想。 此外,安装在同一报头上的两个检测器元件之间的这种光隔离技术或交叉干扰抑制也允许仅使用覆盖两个检测器的同一窄带通干涉滤波器。 因此,分别用于信号和参考通道的滤波器的热跟踪也接近完美,因为两个通道共享相同的滤波器。

    • A sporting game in which a game ball that behaves differently from a conventional soccer ball is kicked from a starting point toward an end point for the purpose of getting the game ball in the end point in as few as strikes as possible and, if this is not accomplished in one kick, then the game ball is kicked one or more additional times until it is in the end point. However, unlike the direction of travel for a conventional ball, the game ball's direction of travel is to the right when a counterclockwise spin is applied at a point of contact with the player's foot, to the left when a clockwise spin is applied at the point of contact, and straight when a top spin is applied at the point of contact.
    • 一种运动游戏,其中与常规足球的行为不同的游戏球从起点向终点踢出,目的是尽可能少地敲击游戏球,并且如果这是 没有在一个踢中完成,然后游戏球被踢了一次或多次,直到它在终点。 然而,与常规球的行进方向不同,当在与玩家的脚接触的点处施加逆时针旋转时,游戏球的行进方向向右,当在该点处施加顺时针旋转时,游戏球的方向向右移动 的接触,当在接触点施加顶部旋转时为直线。

    • The concentration of a gas species is detected by using a single beam NDIR gas sensor in which an infrared source element is driven at two different temperatures, a feed back loop senses an operation voltage of the source, a differential gain amplifier creates a high cycle amplified output during a high cycle and a low cycle amplified output during a low cycle while a controller synchronizes the source driver so that a signal processor can determine the gas concentration through use of the high cycle amplified output and the low cycle amplified output. The infrared source can be a non-genuine blackbody source such as an incandescent miniature light bulb when the sample chamber is a thermally insulated aluminum tube that is maintained at a preselected temperature greater than ambient so that the glass envelope of the bulb is maintained at an equilibrium temperature (such as approximately 30 degrees Celsius plus or minus two degrees Celsius) during its low cycle operation state.
    • 通过使用其中红外源元件在两个不同温度下驱动的单束NDIR气体传感器来检测气体种类的浓度,反馈回路感测源的操作电压,差分增益放大器产生高周期放大 在低周期期间在高周期和低周期放大输出期间输出,同时控制器使源极驱动器同步,使得信号处理器可以通过使用高周期放大输出和低周期放大输出来确定气体浓度。 当样品室是保持在比环境温度大的预选温度的绝热铝管时,红外源可以是非真正的黑体源,例如白炽灯微型灯泡,使得灯泡的玻璃封套保持在 在其低循环运行状态期间的平衡温度(例如约30摄氏度加或减2摄氏度)。
