摘要： A DRM scheme that may be optionally invoked by the owner. With the DRM protection turned on, the media is encrypted before it is distributed in a P2P network, and is decrypted prior to its use (play back). The peers may still efficiently distribute and serve without authorization from the owner. Nevertheless, when the media is used (played back), the client node must seek proper authorization from the owner. The invention further provides a hierarchical DRM scheme wherein each packet of the media is associated with a different protection level. In the hierarchical DRM scheme of the invention there is usually an order of the protection level. As a result, in one embodiment of the invention, the decryption key of a lower protection layer is the hash of the decryption key at the higher protection level. That way, a user granted access to the high protection layer may simply hold a single license of that layer, and obtain decryption keys of that layer and below. The invention further provides for a process for managing digital rights to a scalable media file wherein a different encryption/decryption key is used to encrypt each truncatable media packet with a base layer without requiring additional storage space to store the key.

摘要： Peer-to-peer communications sessions involve the transmission of one or more data streams from a source to a set of receivers that may redistribute portions of the data stream via a set of routing trees. Achieving a comparatively high, sustainable data rate throughput of the data stream(s) may be difficult due to the large number of available routing trees, as well as pertinent variations in the nature of the communications session (e.g., upload communications caps, network link caps, the presence or absence of helpers, and the full or partial interconnectedness of the network.) The selection of routing trees may be facilitated through the representation of the node set according to a linear programming model, such as a primal model or a linear programming dual model, and iterative processes for applying such models and identifying low-cost routing trees during an iteration.

摘要： An automated arrangement for parsing location descriptions is provided in which semantic verification is integrated into a parsing process to reduce the generation of false results. The semantic verification involves checking up to three semantic relationships between keywords (i.e., syntactical components) parsed from the location description in a tokenization process to determine if a tokenization result is valid. The semantic relationships include: a) a spatial “part-of” relationship between location keywords; b) a spatial “near-by” relationship; and, c) a spatial “intersect” relationship. The semantic relationships between particular locations may be pre-calculated and stored as extended vocabulary to enable the semantic verification to occur early in the parsing process to thus increase overall parsing efficiency. The results of the parsing are sorted based on a rank score that is derived using the semantic relationships between the locations.

摘要： Microlenses are fabricated with a refractive-index gradient. The refractive-index gradient is produced in a microlens material such that the refractive index is relatively higher in the material nearest the substrate, and becomes progressively lower as the layer gets thicker. After formation of the layer with the refractive-index gradient, material is etched from the layer through a resist to form microlenses. The index of refraction can be adjusted in the microlens material by controlling oxygen and nitrogen content of the microlens materials during deposition. High-oxide material has a lower index of refraction. High-oxide material also exhibits a faster etch-rate. The etching forms the material into a lens shape. After removal of the resist, the microlenses have a lower relative refractive index at their apex, where the index of refraction preferably approaches that of the ambient surroundings. Consequently, light loss by reflection at the ambient/microlens interface is reduced.

摘要翻译： 用折射率梯度制造微透镜。 在微透镜材料中产生折射率梯度，使得最靠近衬底的材料的折射率相对较高，随着层变厚而变得越来越低。 在形成具有折射率梯度的层之后，通过抗蚀剂从层中蚀刻材料以形成微透镜。 通过在沉积期间控制微透镜材料的氧和氮含量，可以在微透镜材料中调整折射率。 高氧化物材料的折射率较低。 高氧化物材料也具有更快的蚀刻速率。 蚀刻将材料形成为透镜形状。 去除抗蚀剂后，微透镜在其顶点处具有较低的相对折射率，其中折射率优选接近周围环境的折射率。 因此，减少了在环境/微透镜界面处的反射的光损失。

摘要： A “code optimizer” provides various techniques for optimizing arbitrary XOR-based codes for encoding and/or decoding of data. Further, the optimization techniques enabled by the code optimizer do not depend on any underlining code structure. Therefore, the optimization techniques provided by the code optimizer are applicable to arbitrary codes with arbitrary redundancy. As such, the optimized XOR-based codes generated by the code optimizer are more flexible than specially designed codes, and allow for any desired level of fault tolerance. Typical uses of XOR-based codes include, for example, encoding and/or decoding data using redundant data packets for data transmission real-time communications systems, encoding and/or decoding operations for storage systems such as RAID arrays, etc.

摘要： A microlens array with reduced or no empty space between individual microlenses and a method for forming the same. The microlens array is formed by patterning a first set of microlens precursors in a checkerboard pattern on a substrate. The first set of microlens precursors is reflowed and cured into first microlenses impervious to subsequent reflows. Then, a second set of microlens precursors is patterned in spaces among the first microlenses, reflowed and cured into second microlenses. The reflows and cures can be conducted under different conditions, and the microlenses may be differently sized. The conditions of the reflows can be chosen to ensure that the focal lengths of microlenses are optimized for maximum sensor signal.

摘要： Distributed computing devices comprising a system for sharing computing resources can provide shared computing resources to users having sufficient resource credits. A user can earn resource credits by reliably offering a computing resource for sharing for a predetermined amount of time. The conversion rate between the amount of credits awarded, and the computing resources provided by a user can be varied to maintain balance within the system, and to foster beneficial user behavior. Once earned, the credits can be used to fund the user's account, joint accounts which include the user and others, or others' accounts that do not provide any access to the user. Computing resources can be exchanged on a peer-to-peer basis, though a centralized mechanism can link relevant peers together. To verify integrity, and protect against maliciousness, offered resources can be periodically tested.
