    • A device for generating hydrogen gas is provided. The device (101) comprises a first hydrogen-containing composition (107) that reacts with a second composition to evolve hydrogen gas; a dispenser (105) adapted to apply the first composition to a first porous member (109); and a conduit (111) adapted to supply the second composition to the first porous member. In a preferred embodiment, the first composition is selected from the group consisting of hydrides, borohydrides and boranes, the second composition is water, and the dispenser is spring-loaded and is charged with the first composition. As the first composition reacts with water at the interface to evolve hydrogen gas, the dispenser forces the reaction product across the interface and out of the dispenser, where it will not interfere with the progress of the hydrogen evolution reaction.

    • An aerial reconnaissance system generates imagery of a scene that meets resolution or field of view objectives automatically and autonomously. In one embodiment, a passive method of automatically calculating range to the target from a sequence of airborne reconnaissance camera images is used. Range information is use for controlling the adjustment of a zoom lens to yield frame-to-frame target imagery that has a desired, e.g., constant, ground resolution or field of view at the center of the image despite rapid and significant aircraft altitude and attitude changes. Image to image digital correlation is used to determine the displacement of the target at the focal plane. Camera frame rate and aircraft INS/GPS information is used to accurately determine the frame to frame distance (baseline). The calculated range to target is then used to drive a zoom lens servo mechanism to the proper focal length to yield the desired resolution or field of view for the next image. The method may be performed based on parameters other than range, such as aircraft height and stand off distance.
    • 空中侦察系统自动和自主地生成满足解决方案或视野目标的场景的图像。 在一个实施例中,使用从空中侦察摄像机图像序列自动地计算到目标的范围的被动方法。 范围信息用于控制变焦镜头的调节,以产生在图像中心具有期望的,例如恒定的地面分辨率或视场的帧到目标图像,尽管飞行器的高度和姿态快速且显着 变化。 图像到图像数字相关用于确定目标在焦平面处的位移。 摄像机帧率和飞机INS / GPS信息用于准确确定帧到帧距离(基线)。 然后将计算出的目标范围用于将变焦镜头伺服机构驱动到适当的焦距,以产生下一图像的期望分辨率或视场。 该方法可以基于除了范围之外的参数,例如飞行器高度和离开距离来执行。

    • A holder for a plurality of dry cells comprises a tray having a pair of open-top compartments, each receiving a plurality of batteries arranged in series and biased into engagement with one another by a contact spring. A retainer projects over each compartment from a common side wall of the compartments and prevents certain batteries from being removed from their normal positions through the open tops of the compartments, while permitting such removal of other batteries. Sufficient lateral clearance is provided to permit the batteries to move somewhat in response to mechanical shock forces without breaking a desired electrical contact.
