    • A peer-to-peer cache architecture stores peer address certificates in different cache segments according to the number of IDs being stored and their relative distance in the peer name space. The cache instantiates regions of decreased range and increased granularity as additional information from close peers is learned. In a large peer cloud where the number of instantiated IDs is not known, each succeeding cache region covers one tenth of the preceding cache region. For peers with multiple IDs registered locally, the segmented cache of the present invention combines overlapping segments of the same granularity to eliminate the duplication of information that would otherwise occur. A cache tree, an instantiated segment tree, and an uninstantiated segment tree are arranged in red-black trees to simplify the search and proper placement and instantiation of information.
    • 对等缓存体系结构将对等体地址证书存储在不同的高速缓存区段中,根据存储的ID数量及其在对等体名称空间中的相对距离。 随着从邻近对等体的附加信息被学习,高速缓存实例化了范围减小和粒度增加的区域。 在实例化ID的数量不大的大对等体云中,每个后续高速缓存区域覆盖前一高速缓存区域的十分之一。 对于在本地注册的多个ID的对等体,本发明的分段高速缓存组合相同粒度的重叠段以消除否则将发生的信息的重复。 一个缓存树,一个实例化的分段树和一个无创的分段树被布置在红黑树中,以简化搜索和信息的正确放置和实例化。

    • An improved excimer laser is disclosed. In one embodiment, the laser includes laser beam generating circuitry operable to generate a laser beam and a vessel enclosing the laser beam generating circuitry. The vessel contains a volume of gas conducive to the formation of the laser beam by the laser beam generating circuitry. The vessel has a wall with a beam aperture formed therein to permit the laser beam generated by the laser beam generating circuitry to pass through it. A window mount assembly is attached to the wall of the vessel. The window mount assembly encloses a beam cavity and has a window that transmits the laser beam. The window is positioned at a first, closed end of the beam cavity. The beam cavity has a second, open end adjoining the beam aperture formed in the vessel wall. The beam cavity has a lateral surface extending between the first and second ends. A plenum lies outside the beam cavity. A gas handling system extracts the gas from the vessel and provides the gas to the plenum. A slot formed in the window mount assembly extends between the plenum and the lateral surface of the beam cavity. The slot forms a gas inlet aperture in the lateral surface of the beam cavity proximate to the first end of the beam cavity. The slot provides a flow of gas from the plenum to the beam cavity.

    • A regenerative amplifier design capable of operating at high energy per pulse, for instance, from 20-100 Joules, at moderate repetition rates, for instance from 5-20 Hertz is provided. The laser amplifier comprises a gain medium and source of pump energy coupled with the gain medium; a Pockels cell, which rotates an incident beam in response to application of a control signal; an optical relay system defining a first relay plane near the gain medium and a second relay plane near the rotator; and a plurality of reflectors configured to define an optical path through the gain medium, optical relay and Pockels cell, such that each transit of the optical path includes at least one pass through the gain medium and only one pass through the Pockels cell. An input coupler, and an output coupler are provided, implemented by a single polarizer. A control circuit coupled to the Pockels cell generates the control signal in timed relationship with the input pulse so that the input pulse is captured by the input coupler and proceeds through at least one transit of the optical path, and then the control signal is applied to cause rotation of the pulse to a polarization reflected by the polarizer, after which the captured pulse passes through the gain medium at least once more and is reflected out of the optical path by the polarizer before passing through the rotator again to provide an amplified pulse.

    • Imaging systems in which an undedicated optical component—i.e., a component that would be present in the system even in the absence of image stabilization—is configured to undergo corrective motion and/or other correction of image data, and thus to function as a stabilization component. The stabilization component may be a mirror and/or a lens, and a positioner may be provided to tilt, rotate, and/or otherwise precisely adjust the position and orientation of the stabilization component to improve image resolution, compensate for platform motions such as platform vibration, and/or improve image tracking. Because an undedicated optical component functions as the stabilization component, the stabilization occurs upstream, rather than downstream, from separation (if any) of the incoming image data into two or more beams. As a result, only one stabilization component is required regardless of whether the system is configured to split the image data into multiple data channels, and imaging systems as described herein therefore may be particularly well-suited for integration into a shared-aperture imaging system. In some embodiments, the coefficients of thermal expansion of selected system components—including optics, optical support structures, and/or positioners—may be substantially the same or closely matched.
    • 未成像的光学部件(即,即使在不存在图像稳定的情况下也将存在于系统中的部件)的成像系统被配置为进行图像数据的校正运动和/或其他校正,并且因此用作稳定 零件。 稳定部件可以是镜和/或透镜,并且可以设置定位器以倾斜,旋转和/或以其他方式精确地调节稳定部件的位置和取向以提高图像分辨率,补偿诸如平台的平台运动 振动和/或改善图像跟踪。 由于未被校正的光学部件用作稳定部件,所以稳定发生在输入图像数据分离成两个或更多个光束的上游而不是下游。 因此,不管系统被配置为将图像数据分割成多个数据通道,仅需要一个稳定组件,因此,如本文所述的成像系统可能特别适合于集成到共享孔径成像系统中。 在一些实施例中,所选择的系统组件(包括光学器件,光学支撑结构和/或定位器)的热膨胀系数可以是基本上相同或紧密匹配的。

    • In a typical peer-to-peer network, any user of the peer-to-peer network may request a lookup of a key and its associated value. To limit access to a stored key-value pair, a user node may generate a registration message for a key-value pair. The value may include the payload to be stored at the storage node, and an access list containing one or more retrieval identifiers indicating one or more users authorized to access the payload. In some cases, the registration message may also include an encrypted payload which is encrypted with a group key. The group key may be included in the registration message, and may be encrypted with an encryption key which is known by the authorized user.
    • 在典型的对等网络中,对等网络的任何用户可以请求查询密钥及其相关联的值。 为了限制对存储的键值对的访问,用户节点可以生成用于键值对的注册消息。 该值可以包括要存储在存储节点处的有效载荷,以及包含指示被授权访问有效载荷的一个或多个用户的一个或多个检索标识符的访问列表。 在一些情况下,注册消息还可以包括用组密钥加密的加密有效载荷。 组密钥可以被包括在注册消息中,并且可以被授权用户已知的加密密钥加密。

    • In a distributed hash table (DHT), a participating node has a routing cache associating nodes in the DHT with their respective network addresses. Messages can be routed with the routing table using prefix-matching or numerical-closeness without requiring rigid structuring of the node's cache. Entries in the cache may be replaced using routing information obtained from en route messages. Entries in the routing cache may be replaced without regard for the nodeIDs in or entering the routing cache, and/or without structuring the routing cache according to the nodeIDs placed therein. Cache entries may be replaced randomly.
