    • An optical filter for intentionally blurring camera images has a generally transparent material and a plurality of optical distortions formed in the transparent material. Placement of the transparent material longitudinally in the optical path of a camera in front of the aperture stop allows contouring the blur across the image plane. That contour is preferably random, so as to defeat digital methods for image restorations. Additionally, a linear gradient is utilized to even-out the ground resolution on oblique cameras or localized to even-out resolution on cameras that have areas of unwanted high resolution.
    • 用于有意模糊照相机图像的滤光器具有通常透明的材料和在透明材料中形成的多个光学失真。 将透明材料纵向放置在孔径光阑前面的照相机光路中允许在整个图像平面上形成模糊。 该轮廓优选是随机的,以便击败用于图像恢复的数字方法。 另外,使用线性梯度来平滑倾斜相机上的地面分辨率,或者在具有不需要的高分辨率区域的相机上将其局限于均匀分辨率。

    • Aerodynamic control apparatus which deflects a control-surface-member into the airstream for creating drag on an aircraft. This drag flap mechanism includes a strut and hinge plate which together constrain the control-surface-member to move in a coupled manner about mutually perpendicular axes. There is an actuator from the controls of the pilot which moves the hinge plate which in turn moves the control-surface-member in that coupled manner. It moves between a fully feathered position presenting minimal resistance to the airstream and a fully operative position presenting maximum resistance to the airstream. The preferred embodiment of the drag flap mechanism is as a continuation of the wing tips where two control-surface-members are hinged about a common axis on the hinge plate so they can open like a split flap. The motion of these two control-surface-members are constrained to allow the force of the air opening the two surfaces to assist in pushing the two surfaces more into the airstream. An alternate embodiment is a single flap that opens into the airstream from any surface on the aircraft but most usefully on the top surface of the wing inboard of the ailerons. Either embodiment can be used for both yaw control and for glide slope control as can many prior art drag flaps. The advantage of the present invention is with extremely large drag forces. The augmenting force is a function of the side slip angle and incorrect actuation (pilot error or hydraulic failure) will not be augmented. In fact without any actuation force, this invention can perform the same function as a large fixed vertical stabilizer and with more deflection on both sides, there is more stabilizing effect.
    • 空气动力学控制装置,其将控制表面构件偏转到气流中,以在飞行器上产生阻力。 这种拖曳襟翼机构包括支柱和铰链板,它们一起约束控制表面构件以相互垂直的轴线联接的方式移动。 有一个来自飞行员的控制器的致动器,该致动器使铰链板移动,该铰接板又以该联接的方式移动控制表面部件。 它在对气流具有最小阻力的完全顺桨位置和呈现对气流的最大阻力的完全操作位置之间移动。 拖曳翼片机构的优选实施例是作为翼尖的延续,其中两个控制表面构件围绕铰链板上的共同轴线铰接,因此它们可以像分裂翼片一样打开。 这两个控制表面构件的运动被限制为允许两个表面的空气打开的力有助于将两个表面更多地推入空气流。 一个替代实施例是从飞机上的任何表面打开到空气流中的单个翼片,但最有效地在副翼的内翼的顶表面上。 任何一个实施例都可以用于偏航控制和用于滑行斜坡控制,如许多现有技术的拖曳片。 本发明的优点是具有非常大的阻力。 增强力是侧滑角的函数,不会增加不正确的致动(导向误差或液压故障)。 实际上没有任何驱动力,本发明可以起到与大型固定式垂直稳定器相同的作用,并且在两侧具有更大的偏转,所以具有更多的稳定效果。

    • An aircraft comprises first and second wings positioned on opposite sides of a longitudinal axis, a first forward opening control surface attached to an upper surface of the first wing, and a second forward opening control surface attached to an upper surface of the second wing, wherein each of the first and second hinges is canted with respect to a direction perpendicular to a longitudinal axis of the aircraft. A method of providing yaw control of an aircraft is also provided. The method comprises the steps of providing a first forward opening, canted spoiler in a top surface of a first wing of the aircraft, providing a second forward opening, canted spoiler in a top surface of a second wing of the aircraft, and operating the first and second spoilers differentially to create a yaw moment. The creation of yaw moments without any down force has application in sweptback wings where the tips are behind the center of gravity of the aircraft. The advantage is in reducing radar cross section over traditional (forward hinged, rearward opening) spoilers where there must be a spoiler on the bottom side to counter the down force created by the top spoiler.
    • 飞机包括位于纵轴相对侧的第一和第二翼,附接到第一翼的上表面的第一向前开启控制表面和附接到第二翼的上表面的第二向前开启控制表面,其中 第一和第二铰链中的每一个相对于垂直于飞行器的纵向轴线的方向倾斜。 还提供了提供飞行器的偏航控制的方法。 该方法包括以下步骤:在飞行器的第一翼的顶表面中提供第一向前开口的倾斜扰流板,在飞行器的第二翼的顶表面中提供第二向前开口,倾斜扰流板,并操作第一 和第二扰流板差分地产生偏航力矩。 在没有任何向下的力的情况下创建偏航力矩可以应用在飞行器的翼部,其中尖端在飞行器的重心之后。 优点在于减少传统(前向铰链,向后开启)扰流板的雷达横截面,其中底部必须有扰流板,以抵抗由顶部扰流器产生的向下力。

    • The method of landing a flying wing type aircraft in a crosswind includes the steps of disengaging the nose landing wheel upon impact with the runway so that it is free to castor; and thereafter, engaging the nose wheel after a specific time period after the nose wheel impacts the runway such that the nose wheel is steerable. The system for landing a flying wing type aircraft in a crosswind on a runway includes a steering system for steering the nose wheel, the steering system having a first condition wherein it controls the angular position of nose wheel and a second condition wherein the wheel is free to castor. A control system moves the steering system from the first condition to the second condition upon the wheel contacting the runway and moves the steering system back to the first condition after a specified time after the wheel contacts the runway.

    • An endotracheal tube having an audio aid for indicating the accurate placement thereof. In a first preferred embodiment, the invention comprises a cuffed ETT having distal and proximal ends, the latter having a mechanical noise-making apparatus formed thereon that provides an audible signal when air passes therethrough. In a second preferred embodiment, the invention comprises the combination of a cuffed ETT having distal and proximal ends and an insertion rod for stiffening the ETT during insertion. The insertion rod is coupled to an electrically-powered noise maker formed upon the distal end thereof to produce an audible sound before air flow through the ETT is established. In both embodiments the correct placement is determined by the unaided ear hearing the noise coming from both sides of the chest. If sound is from one side only the insertion is too deep. If the sound is heard from the stomach the ETT is in the esophagus instead of trachea and should be pulled out and reinserted in such a way that it press more forcefully in the ventral direction.
