  • Patent number: 7686909
    Abstract: A method for reel-type packaging flexible printed circuit boards (FPCs) is disclosed. Firstly, a flexible plate having a plurality of FPC patterns is cut out to form several bar-like materials, wherein each of the bar-like materials has a plurality of aligned FPCs thereon. Subsequently, the bar-like materials are wound onto a reel one by one to form a reel-type package so as to prevent the FPCs from crumpling, curving and deforming when suffering an external force.

  • Publication number: 20070132918
    Abstract: A flat display, a flat panel display and a backlight module are disclosed. The flat display module comprises the flat panel display and the backlight module. The flat panel display comprises an upper polarizer and a lower polarizer. The lower polarizer includes a first diffusion layer. The backlight module comprises a light emitting device, a prism sheet and a light guide plate. A light beam is provided by the light emitting device. The prism sheet is one-dimensional prism array structure. The light guide plate includes a second diffusion layer for diffusing the light beam. The first diffusion layer has an optical haze greater than the optical haze of the surface of the upper polarizer. Accordingly, thin thickness and high brightness are achieved for the flat display.

  • Patent number: 5912257
    Abstract: Styryl dyes and compositions which exhibit superior two-photon absorption cross-sections and are useful in two-photon pumped cavity lasing, two-photon pumped upconversion lasing, optical power limiting, optical power stabilization, optical signal reshaping, and infrared beam detection and indication are disclosed. Also disclosed are multiphasic nanostructured composites which include a glass having pores, an optically active coating material on the pore surface, and a polymeric material in the pores. These composites are useful in producing multifunctional optical materials, such as broadly tunable lasers. Methods for killing cells and viruses using a photosensitizer and a two-photon upconverting dye are also described. These methods are especially useful to kill cells and viruses in biological materials, such as in photodynamic therapy of tumors and cancers or blood purification protocols.

  • Patent number: 5909476
    Abstract: In the present invention, an iterative process is provided for cone-beam tomography (parallel-beam and fan-beam geometries are considered as its special cases), and applied to metal artifact reduction and local reconstruction from truncated data, as well as image noise reduction. In different embodiments, these iterative processes may be based upon the emission computerized tomography (CT) expectation maximization (EM) formula and/or the algebraic reconstruction technique (ART). In one embodiment, generation of a projection mask and computation of a 3D spatially varying relaxation factor are utilized to compensate for beam divergence, data inconsistence and incompleteness.
