    • A speaker mount includes a support structure attachment, an adjustable mount connected to the structure attachment and including a first connector, and a speaker attachment including a second connector. The first and second connectors may selectively be connected or disconnected, permitting a speaker to be connected to and disconnected from the remainder of the mount. The first connector is mounted to a ball. A lock plate is mounted at an opposing side of the ball from the first connector. A fastener controls the distance between the first connector and the lock plate. In one position, the fastener draws the lock plate and first connector towards one another, fixing the lock plate in a position on the ball, and in another position allows the first connector to be moved relative to the ball. The mount permits orientation of a speaker in a variety of positions relative to a support structure.
    • 扬声器支架包括支撑结构附件,连接到结构附件的可调节安装件,并且包括第一连接器以及包括第二连接器的扬声器附件。 可以选择性地连接或断开第一和第二连接器,从而允许扬声器连接到安装座的其余部分并与之隔离。 第一个连接器安装在一个球上。 锁定板安装在与第一连接器相对的球的相对侧。 紧固件控制第一连接器和锁定板之间的距离。 在一个位置,紧固件将锁定板和第一连接器朝向彼此拉紧,将锁定板固定在球上的位置,并且在另一位置允许第一连接器相对于球移动。 安装件允许扬声器相对于支撑结构在各种位置的取向。

    • A tube-mounted inclined optical flat for improving the stealth capability of an optical aperture is disclosed. The optical flat has a light-absorbing finish on its rear surface, and is mounted in front of existing instrument optics. The light from the scene being viewed passes through the optical flat and is undistorted. Any light that is reflected from the optical flat is absorbed by the light-absorbing tube. Light that enters the distal end of tube is absorbed in the same manner. Any light entering the instrument optics from the observer's end and internal reflected light emanate from within the optics. Much of this light is absorbed by the rear finish on the optical flat. Selection of the optics' virtual focal points and placement of the optical flat relative to the optics reduce the size requirement of the rear finish on the optical flat.
    • 公开了一种用于提高光学孔的隐形能力的管式倾斜光学平面。 光学平板在其后表面上具有光吸收光洁度,并且安装在现有仪器光学器件的前面。 来自被观察场景的光通过光学平面并且是未失真的。 从光学平面反射的任何光被光吸收管吸收。 进入管末端的光以同样的方式被吸收。 从观察者的端部进入仪器光学器件的任何光和内部反射光从光学器件内发出。 这种光线大部分被光学平面上的后面完成所吸收。 选择光学器件的虚拟焦点和光学平面相对于光学元件的放置可以减少光学平面上后面光洁度的尺寸要求。
