摘要： A multiple protection group (MPG) erasure-resilient coding method for constructing MPG codes for encoding and decoding data. The MPG codes constructed herein protect data chunks of data in multiple protection groups and subgroups. In general, the MPG erasure-resilient codes are constructed by locating data chunks into multiple protection groups and assigning at least one parity chunk to each protection group. Basic MPG codes are constructed from existing Maximum Distance Separable (MDS) codes by splitting at least some of the parity chunks into local parities for each of the multiple protection groups and projecting local parities onto each of the groups. Generalized MPG codes have a Maximally Recoverable property that can be used to determine whether an erasure pattern is recoverable or unrecoverable. Generalized MPG codes can recover any erasure pattern that is recoverable.

摘要： 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.

摘要： 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.
摘要翻译：一个“大众文件共享器”（MFS）提供了一个质量P2P文件共享协议，可以通过P2P网络提供可选的按需文件访问。与传统的P2P文件共享不同，MFS同时异步共享大量文件，同时提供对共享文件的可选按需（同步）访问。 MFS使用唯一的元数据结构与对等文件/文件夹版本分析和对等文件/文件夹可用性分析结合，以共享可能包含任意数量的文件夹，子文件夹和文件的复杂目录结构。共享可以是异步的和/或同步的。具体来说，文件共享通常作为跨网络的异步分发来完成。然而，当特定对等体想要直接访问特定文件时，使用按需访问模式来启用共享文件的同步传递。这种异步和同步文件分发的组合使MFS能够支持许多应用程序，如按需电影查看，文件/文件夹浏览等。

摘要： 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.

摘要： 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.
摘要翻译：一种自适应编码存储系统，其使用自适应擦除弹性码（ERC），其根据所分配文件的大小改变用于编码的片段的数量。自适应ERC可以大大提高P2P存储的效率和可靠性。还可以实现用于P2P存储应用的多个过程。在一个实施例中，小的动态数据文件被转移到更可靠的对等体或甚至服务器，而使用不可靠对等体的存储容量来存储大而静态的文件。此外，为了平衡贡献和收益，对等体应该承载与存储在P2P网络中相同数量的内容。因此，不可靠的对等体被允许分配更少的数据，并且允许更可靠的对等体分发更多的数据。而且，分配较小的文件分配成本较高，分配较大的文件分配成本较低。

摘要： 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.

摘要： 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.
