摘要:
An Internet Service Provider (ISP)-aware peer-to-peer (P2P) content exchange system and method for exchanging content over a P2P network using the Internet. The system and method accounts for the type of relationship between peers and classifies and groups each peer according to these relationships. A peer overlay is constructed such that peers within a peer's neighborhood are favored over those peers outside of the neighborhood. Peer scheduling is utilized to exchange information about the availability of blocks of content. This block availability information can be exchanged differently and its frequency changed depending on a peer's classification. Peers are selected for block exchange based on their classification. A peer selection proportion may be defined that dynamically changes depending on contents of a peer's download buffer. The blocks to be exchanged then are selected based on the block availability information, such that the rarest blocks are exchanged before the more common blocks.

A serverless peer-to-peer (P2P) multi-party real-time audio communication system and method in which each of the peers takes a turn mixing and compressing the audio and redelivering the compressed audio. An input audio stream is divided or split into frames. At each frame, one peer node is selected to mix and redeliver the audio to the remainder of the peers in the network. The number of frames mixed and redelivered by a certain peer is proportional to its available resources (such as the upload bandwidth or computational power). The P2P audio communication system and method flexibly balances the load of the peers, such that peers having more resources are able to assist peers having fewer resources. This enables the P2P audio communication system and method to conduct a multi-party audio communication session without the need for powerful servers or peers.

A method implemented in a scalable auxiliary graph for simultaneously displaying both traditional hierarchical information and auxiliary information at the same time. The method provides for a scalable auxiliary graph that shows feature interdependencies between a selected feature or sub-feature and any related interdependent primary features and/or sub-features. Here, the scalable auxiliary graph includes a visual anchor connecting the plurality of primary features and sub-features. A visual link is used to connect a currently selected feature or sub-feature to the visual anchor. Visual connector lines are used to link the visual anchor to related interdependent primary features or sub-features. This allows the user to simultaneously visualize relationship between the selected feature and any related interdependent primary features and/or sub-features.

A wrapper type combined magnetic energy generator and a magnetic energy lamp of the present invention belong to the field of illumination. Especially, it is a magnetic energy generator used in the magnetic energy lamp that can produce the electromagnetic energy to excite the illuminative devices. The magnets of the magnetic energy generator are two split type combined magnets. More than one flute is provided on one side of one magnet and the flutes of the two magnets correspond to each other. The fixed spaces are produced between the two flutes of the two magnets. The spaces are communicated with the two flutes to be located exactly. The lamp body of the magnetic energy lamp is provided and fixed on the magnetic energy generator. These two split type combined magnets of the magnetic energy generator wrap the hollow lamp body of the magnetic energy lamp, respectively. The structure of the present invention is simple. It can be made easily and its cost is low. So it provides a reliable technique implementation project for the large-scale industrialization.

Ellipse-shaped microlenses focus light onto unbalanced photosensitive areas, increase area coverage for a gapless layout of microlenses, and allow pair-wise or other individual shifts of the microlenses to account for asymmetrical pixels and pixel layout architectures. The microlenses may be fabricated in sets, with one set oriented differently from another set, and may be arranged in various patterns, for example, in a checkerboard pattern or radial pattern. The microlenses of at least one set may be substantially elliptical in shape. To fabricate a first set of microlenses, a first set of microlens material is patterned onto a support, reflowed under first reflow conditions, and cured. To fabricate a second set of microlenses, a second set of microlens material is patterned onto the support, reflowed under second reflow conditions, which may be different from the first conditions, and cured.
摘要:
A micro-lens and a method for forming the micro-lens is provided. A micro-lens includes a substrate and lens material located within the substrate, the substrate having a recessed area serving as a mold for the lens material. The recessed can be shaped such that the lens material corrects for optical aberrations. The micro-lens can be part of a micro-lens array. The recessed area can serve as a mold for lens material for the micro-lens array and can be shaped such that the micro-lens array includes arcuate, non-spherical, or non-symmetrical micro-lenses.

Microfeature workpieces having microlenses and methods of forming microlenses on microfeature workpieces are disclosed herein. In one embodiment, a method for forming microlenses includes forming a plurality of shaping members on a microfeature workpiece between adjacent pixels, reflowing the shaping members to form a shaping structure between adjacent pixels, depositing lens material onto the workpiece, removing selected portions of the lens material adjacent to the shaping structure such that discrete masses of lens material are located over corresponding pixels, and heating the workpiece to reflow the discrete masses of lens material and form a plurality of microlenses.
摘要:
Content synchronization in a file sharing environment is described. A node in a circle share maintains a version vector that represents that node's knowledge of file synchronization events. Version vector data may be transmitted between nodes of the circle share via a presence service in the form of short notification messages. The version vector data is compared to identify one or more nodes to be synchronized. A resource-aware overlay representing the circle share is computed, and is used to initiate communication to determine which of the available nodes with which to synchronize will provide the most synchronization value to other nodes in the circle share.
摘要:
A microlens array having first and second sets of spherically-shaped microlenses. The second set of spherically-shaped microlenses are located in the areas between individual microlenses of the first set in such a way that there is minimized gapping over the entire microlens array. A semiconductor-based imager includes a pixel array having embedded pixel cells, each with a photosensor, and a microlens array having spherically-shaped microlenses as just described.
