摘要： The present invention provides a method for distinguishing a boundary of an object, and the object itself, from its background. In the method electromagnetic radiation is detected from at least one field of view substantially spanning the boundary of the object and background adjacent to the boundary and superimposed or overlaid as images onto a detector. The method includes correlating spatial transitions in intensity of the overlaid images on the detector with a boundary of the object. When used for determining the attitude of a satellite with respect to the earth, the detector is a thermal infrared detector thereby providing a sharp contrast between the thermal emission of the earth and cold space. The invention provides a simple, effective method and device for determining satellite orientation and/or attitude with respect to a thermal infrared-emitting target body. The sensor includes a segmented limb-looking mirror to provide multiple fields-of-view within the field-of-regard and superimposing these fields-of-view as images onto a common detector. The required resolution can be obtained while providing a wide range of operational orbital altitudes. The attitude of the satellite can vary by a large angle from the minimal orientation while still permitting an accurate determination of attitude. Multiple channels in a modular form provide redundancy, improved accuracy, and the opportunity of providing more diverse configurations. The utilization of uncooled microbolometer arrays as imaging detectors removes the requirement for additional cooling equipment thereby providing a low cost, small size and low mass sensor with configurational flexibility and no moving parts.
摘要翻译： 本发明提供了一种用于区分对象和对象本身的边界与其背景的方法。 在该方法中，从至少一个视野基本上跨越与边界相邻的对象和背景的边界并且叠加或重叠为图像的检测器检测电磁辐射。 该方法包括将检测器上的重叠图像的强度的空间转换与对象的边界相关联。 当用于确定卫星相对于地球的姿态时，检测器是热红外探测器，从而在地球和冷空间的热发射之间形成鲜明的对比。 本发明提供了一种用于确定相对于热红外发射目标体的卫星定向和/或姿态的简单有效的方法和装置。 该传感器包括分段的肢体镜，以在观察区域内提供多个视野，并将这些视场作为图像叠加到公共检测器上。 在提供广泛的操作轨道高度时可以获得所需的分辨率。 卫星的姿态可以从最小方向变化很大的角度，同时仍能准确地确定姿态。 模块化形式的多个通道提供冗余，提高准确度，并提供更多样化配置的机会。 利用未冷却的微热辐射计阵列作为成像检测器消除了对附加冷却设备的需求，从而提供具有配置灵活性和无移动部件的低成本，小尺寸和低质量传感器。

摘要： An Adaptable kite/airfoil preferably for structured kites having effectively “reefable” sub-section(s) typically changing the effective width and/or length of the airfoil, thereby substantially changing the aerodynamic characteristics of the airfoil, using continuous sheet material sections not separated in flight use or in changing the kite aerodynamics. Thus, all of the sheet material, skin of the kite remain with the kite in its various configurations. Seven exemplary embodiments which achieve this approach are described including (1) roll-up section(s) (FIGS. 2A & 2B); (2) integrally contiguous, fold over, over-lapped section(s) (FIGS. 3 & 5); (3) continuous but not integrally contiguous, overlap section(s) using a telescoping arrangement (FIGS. 4A-4C); (4) varyingly compressed and/or aligned battens (FIGS. 5-6); (5) variable wing tips (FIG. 7); (6) center pull-down or up (FIGS. 8 & 9); and (7) in flight expandable/contractible center pulled up or down (FIG. 10).

摘要： A watercraft drag apparatus may extend into the water from either the port or the starboard side of a watercraft or a hull of the watercraft. The drag apparatus may cause an increase in drag on one side of the watercraft. The increase in drag may slow the watercraft to a slower speed than the watercraft can typically maintain under normal power. The increase in drag may also cause the watercraft to change heading, requiring a watercraft pilot to repeatedly correct the heading to maintain an intended course. The watercraft drag apparatus may be useful for fishing, such as when trolling.

摘要： A cylinder sleeve is composed of multiple identical interlocking sleeve elements. Each sleeve element has a circular cylindrical portion and an integral circular arc portion tangent to the cylindrical portion. The circular arc portion has a boss on one end and an offset finger on the other which mates with the boss of an adjacent sleeve element to fix the adjacent sleeve elements together radially.
