摘要:
A projector having a curved field lens and a displaced light modulating display. The system includes at least one light source configured to generate colored light beams, and a prism routing the light beams to the display. The curved field lens is coupled to a face of the prism, and the prism and curved field lens together decenter the light beam from the prism face and uniformly illuminate the display. A center of the display is displaced from the projection lens optical axis. The decentered light beam and the displaced display together generate a favorable shifted boresight of the created image. Dimensions of components of the projector are a function of a curvature of the curved field lens. The greater the curvature of the curved field lens, the smaller the dimensions of the components and the overall projector. The projector may be used in eyewear.

A passively athermalized infrared imaging system includes an object side meniscus lens that forms at least one aspheric surface, and an image side meniscus lens that forms two aspheric surfaces. Each of the meniscus lenses are formed of a material selected from the group consisting of a chalcogenide glass, germanium, silicon, gallium arsenide, zinc selenide and glass. An optical power of the image side meniscus lens is at least 1.6 times an optical power of the object side meniscus lens such that an effective focus position of the imaging system is athermalized over a range of 0 to +40 degrees Celsius.

In an embodiment, a method of aligning elements in a manufacturing process includes placing a middle element onto a base element, the base element forming first alignment features, the middle element forming apertures therethrough corresponding to the first alignment features. The method also includes placing second alignment features of an upper element onto the first alignment features such that the first and second alignment features cooperate, through the apertures, to align the upper element with the base element. An infrared lens assembly includes a lens formed of an infrared transmitting material that is disposed within a carrier of a base material, the lens being molded within the carrier with at least one feature that secures the lens to the carrier.

The present invention is a system, data access management utility and a method of generating links between local merchants and a marketing system. For example, the marketing system may be that disclosed in PCT Patent Application No. PCT/CA2009/001605. The present invention may be operable to register members, merchants, community programs, intermediaries and other entities with the marketing system. Embodiments of the present invention may be operable to quickly and efficiently register multiple members and/or multiple merchant store types virtually simultaneously to the marketing system. An automated registration and/or boarding process may be operated by the present invention to undertake such registration and/or boarding of members, merchants, community programs, intermediaries and other entities with the marketing system, including automated boarding of merchants.

The present invention relates to a navigational safety system for visually impaired quadrupeds. An onlay has a right side, a left side, a top side, a bottom side, and a chest side. The onlay is retrofittable to or manufactured into a harness worn by a quadruped. Distance sensors and vibrators are integrated into the onlay and configured to determine the distance between obstacles and provide localized vibration stimulation to the quadruped. The vibration causes the quadruped to change course avoiding the obstacle. In this regard, the localized vibrations are positioned on the right torso, the left torso, and the chest of the quadruped.
摘要:
A compact projector for eyewear including a refractive lens to achromatize an image and to reduce the size of the projector. The compact projector includes two total internal reflection (TIR) prisms, a polarizing beamsplitter, a quarter-wave plate, and the refractive lens combining refractive and reflective power, referred to as catadioptric. In one example, a light source generates light that is directed through a collector, into a first TIR prism, to the polarizing beamsplitter, and to a display panel. The display panel modulates the light and creates an image. The image is directed through the beamsplitter, into a second TIR prism, through a quarter-wave plate, and then to the refractive lens. The refractive lens reflects the image back into the second TIR prism, and which image then exits to a waveguide. In a second example, the display generates an illuminated image which is then processed as in the first example.
