摘要： A ridged reflector (10) for use in an optical display (12) comprises a polymeric layer (70) having a ridged surface (32) and an opposite surface (34) opposite the ridged surface (32). The ridged surface (32) includes a series of ridges (36). Each of said ridges (36) has a first face (42) and a second face (44) intersecting the first face (42). The first face (42) is oriented at a first angle (56) relative to a plane parallel to the opposite surface (34). A reflective metallic layer (68) overlies at least the first faces (42) of the polymeric layer (70). The first angle (56) is adapted to reflect and biasedly focus light obliquely intercepting the first face (56) into a radiation pattern about a normal axis (38) extending orthogonally from the opposite surface (34). The first face (42) may be curved to tailor a shape of the radiation pattern.

摘要： The display device includes an optical cell having a cell front with at least one cell region being capable of an optically transmissive mode and an optically nontransmissive mode with reference to the cell front. The optical cell contains an optically active material responsive to an applied electrical field such that optical properties of the material are controllably changeable. A reflector may be optically coupled to the cell. A prismatic film including a prismatic surface is optically coupled to the optical cell. The prismatic surface preferably comprises a series of prisms. The prisms have first faces and second faces intersecting the first faces. The first faces are oriented to refract light obliquely intercepting the first faces and the second faces are oriented to minimize refractive, reflective, and optical interactions of the light with the second faces. The prismatic film, the cell, and the reflector optically cooperate such that light entering a display at an incident angle is emitted from the display at an exiting angle distinct from the incident angle for viewing of the display.

摘要： A display (200) includes a slanted fringe volume hologram (206) or other optical element that steers light that passes into and out of the display (200) so as to provide angular separation between unmodulated scattered light and modulated reflected light. As a result of the angular separation the effective contrast of the display (200) is improved. By placing the slanted fringe volume hologram (206) below a front polarizer of the display a further reduction in the amount of unmodulated scatter light is achieved. The slanted fringe volume hologram is preferably a hologram of a diffusive object (328), and consequently exhibits a degree of light diffusion that results in a viewing zone of an appreciable angular extent.
摘要翻译：显示器（200）包括倾斜的边缘体积全息图（206）或其他光学元件，其转向进入和离开显示器（200）的光，以提供未调制的散射光和调制的反射光之间的角度间隔。作为角度分离的结果，改善了显示器（200）的有效对比度。通过将倾斜的边缘体积全息图（206）放置在显示器的前偏振器下方，实现未调制散射光量的进一步减少。倾斜的边缘体积全息图优选地是漫射物体（328）的全息图，因此表现出一定程度的光扩散，其导致观察区域具有可观的角度范围。

摘要： In one aspect, a device comprises a means for generating an aerostatic force exclusive of a buoyancy force acting on the device, wherein the aerostatic force acting on the device is a significant portion of a total force acting on the device due to the aerostatic force exclusive of a buoyancy force, a reaction force, and a buoyancy force. In another aspect, a device includes a cavity with a first internal pressure of a first fluid, and a plurality of conduits extending from the cavity to an environment outside of the device with a second pressure different from the first pressure, wherein fluid flows through the plurality of conduits, and an aerostatic force exclusive of a buoyancy force acting on the device is greater than a reaction force acting on the device due to the fluid flow or is a substantial portion of the total force acting on the device.

摘要： An apparatus determines a cursor position in an illumination field of a projector. An obstruction is detected in the illumination field. The cursor position is determined as the point on the obstruction furthest from where the obstruction crosses a border of the illumination field. A distance to the point on the obstruction is determined and compared to a distance to a point not on the obstruction. Gestures are recognized as a function of movement of the obstruction and the determined distances.

摘要： A ridged reflector (10) permits operation of an optical display device (12) in ambient light, which may be supplemented by artificial back-lighting. The ridged reflector (10) for use in an optical display (12) includes a transparent polymeric layer (70) having a ridged surface (32). The ridged surface (32) includes a series of ridges (36). Each of the ridges (36) has a first face (42) and a second face (44) preferably intersecting the first face (42). A reflective layer (68) overlies the first face (42) of each of the ridges (36). The second face 44 (44) is generally light-transmissive and substantially free of a reflective layer (68). The ridged surface (32) has an opposite surface (34) opposite the ridged surface (32). The second face (44) of each of said ridges (36) allows optical communication with the opposite surface (34) for optional back-lighting of the optical display device.
