    • Off-axis total internal reflection Fresnel lenses and projection screens are disclosed that, when combined, enable construction of projection assemblies for rear-projection-type screen devices (e.g., projection television systems) that are thinner, provide easier handling and maintenance, and have improved contrast, focusing, and resolution when compared with conventional projection screen devices. The off-axis Fresnel lens comprises a plurality of concentric, outwardly-extending, total internal reflection-type prism facets, the top side of which may be aspherical. Embodiments of the invention also include projection screens having at least one diffuser and one lenticular lens. In addition, one or more opaque layers may be used to improve contrast. The various components, e.g., the fresnel lens, the diffuser, the lenticular lens(es), the opaque layer(s), etc. are all combined, or connected, in such a way as to eliminate substantially all air gaps within the connections.

    • Methods, apparatus, and systems for performing fault diagnosis are disclosed herein. In certain disclosed embodiments, methods for diagnosing faults from compressed test responses are provided. For example, in one exemplary embodiment, a circuit description of an at least partially scan-based circuit-under-test and a compactor for compacting test responses captured in the circuit-under-test is received. A transformation function performed by the compactor to the test responses captured in the circuit-under-test is determined. A diagnostic procedure for evaluating uncompressed test responses is modified into a modified diagnostic procedure that incorporates the transformation function therein. Computer-readable media comprising computer-executable instructions for causing a computer to perform any of the disclosed methods are also provided. Likewise, computer-readable media comprising lists of fault candidates identified by any of the disclosed methods or circuit descriptions created or modified by the disclosed methods are provided.

    • An off-axis Fresnel lens is disclosed that, when combined with a rear projection screen (comprising, e.g., a lenticular lens, a diffuser, or both), enables construction of rear-projection-type screen devices (e.g., projection television systems) that are thinner and have improved contrast and resolution when compared with conventional projection screen devices. The off-axis Fresnel lens comprises a plurality of concentric, outwardly-extending, total internal reflection-type prism facets. Each facet, in turn, comprises top and bottom sides, one or both of which may be flat or outwardly convex. Embodiments of the invention may also include concentric opaque sections that are disposed between successive prisms, between the prism base and the output surface of the Fresnel lens, and/or between the output surface of the Fresnel lens and the input surface of the projection screen in order to improve contrast. Contrast may also be enhanced by laminating the Fresnel lens to the projection screen.
    • 公开了一种离轴菲涅尔透镜,当与后投影屏幕(包括例如双凸透镜,扩散器或两者)组合时,可以构建背投型屏幕装置(例如,投影电视系统) 与传统的投影屏幕装置相比,其更薄并且具有改善的对比度和分辨率。 离轴菲涅耳透镜包括多个同心的,向外延伸的全内反射型棱镜面。 每个小面又包括顶侧和底侧,其中一个或两个可以是平的或向外凸的。 本发明的实施例还可以包括设置在连续棱镜之间,棱镜基座和菲涅尔透镜的输出表面之间和/或菲涅尔透镜的输出表面与投影屏幕的输入表面之间的同心不透明部分 为了改善对比度。 对比度也可以通过将菲涅尔透镜层压到投影屏幕来增强。
