    Abstract: A high-rate Reed-Solomon erasure resilient codes (ERC) system and method for generating and implementing Reed-Solomon erasure-resilient codes for use in high-rate applications. High-rate applications are applications where the number of coded messages is significantly higher (such as an order of magnitude) than the number of original messages. The Reed-Solomon ERC system uses a scalar vector multiplication and addition technique and a direct inversion technique. The direct inversion technique uses specific generator matrices, including a modified Vandermonde Matrix and a Cauchy Matrix, to directly calculate an inverse of the sub-generator matrix of receiving ERC-coded messages. The scalar vector multiplication and addition technique generates high-rate Reed-Solomon codes and performs scalar vector multiplication and addition on the Galois Field for the Reed-Solomon erasure encoding/decoding operations. In effect, the Reed-Solomon codes are “tuned” for use in the high-rate environment.

    Abstract: A “Mass File Sharer” (MFS) provides a mass P2P file sharing protocol with optional on-demand file access across a P2P network. Unlike conventional P2P file sharing, the MFS simultaneously asynchronously shares large numbers of files, while providing optional on-demand (synchronous) access to shared files. The MFS uses a unique metadata structure in combination with an inter-peer file/folder version analysis and an inter-peer file/folder availability analysis to share complex directory structures that may include any number of folders, sub-folders, and files. Sharing may be asynchronous and/or synchronous. Specifically, file sharing is generally accomplished as an asynchronous distribution across the network. However, when a particular peer wants direct access particular files, an on-demand access mode is used to enable synchronous delivery of shared files. This combination of asynchronous and synchronous file distribution enables the MFS to support a number of applications, such as on-demand movie viewing, file/folder browsing, etc.

    Abstract: An adaptive coding storage system that uses adaptive erasure resilient code (ERC) which changes the number of fragments used for encoding according to the size of the file distributed. Adaptive ERC may greatly improve the efficiency and reliability of P2P storage. A number of procedures for P2P storage applications may also be implemented. In one embodiment small, dynamic data files are diverted to the more reliable peers or even a server, while large and static files are stored utilizing the storage capacity of the unreliable peers. Also, for balanced contribution and benefit, a peer should host the same amount of content as it stored in the P2P network. As a result, unreliable peers are allowed to distribute less data, and more reliable peers are allowed to distribute more. Also, smaller files are assigned a higher distribution cost, and the larger files are assigned a lower distribution cost.

    Abstract: A microlens structure includes lower lens layers on a substrate. A sputtered layer of glass, such as silicon oxide, is applied over the lower lens layers at an angle away from normal to form upper lens layers that increase the effective focal length of the microlens structure. The upper lens layers can be deposited in an aspherical shape with radii of curvature longer than the lower lens layers. As a result, small microlenses can be provided with longer focal lengths. The microlenses are arranged in arrays for use in imaging devices.

    Abstract: A variety of structures and methods used to adjust the shape, radius and/or height of a microlens for a pixel array. The structures affect volume and surface force parameters during microlens formation. Exemplary microlens structures include a microlens frame, base, material, protrusions or a combination thereof to affect the shape, height and/or radius of the microlens. The frame, base and/or protrusions alter the microlens flow resulting from the heating of the microlens during fabrication such that a height or radius of the microlens can be controlled. The radius can be adjusted by the height differences between the microlens and frame. The bigger the difference, the smaller the radius will be.

    Abstract: A microlens has a surface with an effective index of refraction close to the index of air to reduce reflection caused by change in indices of refraction from microlens to air. The microlens having an index of refraction approximately the same as that of air is obtained by providing a rough or bumpy lens-air surface on the microlens. Features protrude from the surface of a microlens to create the rough surface and preferably have a length of greater or equal to a wavelength of light and a width of less than a sub-wavelength of light, from about 1/10 to ¼ of the wavelength of light. The features may be of any suitable shape, including but not limited to triangular, cylindrical, rectangular, trapezoidal, or spherical and may be formed by a variety of suitable processes, including but not limited to mask and etching, lithography, spray-on beads, sputtering, and growing.
