    摘要: An offset determination system and method permit accurate calculation of an offset of a central feature of an object. The offset determination system and method are particularly suited for, but not limited to, an automatic inspection system for determining the eccentricity of an optical fiber core relative to a theoretical ideal center of an optical fiber termination. The core is extremely smaller (typically between about 50 and 500 times) in size than the termination boundary. An inspection system has a feature imager, one or more boundary segment imagers but preferably four in number, and a machine vision system connected to the foregoing imagers. The feature imager is positioned to capture an image of the feature ( e.g ., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object ( e.g ., termination endface). The machine vision system determines the offset, or eccentricity, based upon the feature image, the one or more boundary segment images, and the offset determination system and method.

    摘要: Metal hydrides are activated by an electrochemical procedure. In this procedure, a bulk sample of the corresponding metal is immersed in an aqueous electrolyte and contacted by a cathode, Current passed through the aqueous electrolyte causes electrolysis of the water and a concomitant reaction with the formation of metal hydride. As a result, the metal hydride is fractured and smaller particles result. Additionally, the resulting metal hydride has a substantial amount of absorbed hydrogen. A novel plating method, taking advantage of the reducing power of hydrogen absorbed in a metal hydride, is useful to encapsulate such metal hydride with a variety of metals. Therefore, such hydrides are uniformly coated by using plating solutions without the standard reducing agent and stabilizer.

    摘要: A modular optical fiber ribbon has a repetitive color identifier arrangement for the individual coated fibers defining one or more adjacent modules. Each module is identified by a digital bar-code imprinted or otherwise marked on the top surface of the ribbon so that each individual fiber in the entire ribbon structure is uniquely identified. Each module or portion thereof can be broken out from the ribbon by means of a break-out tool which is sufficiently hard to cut the matrix bonding material which holds the fibers in the ribbon configuration, but which is not hard enough to cut the fiber coating. Methods of removing the coating material of the ribbon cable with an alcoholic matrix expander or an adhesive tape are described.

    摘要: The foregoing problems of the prior art have been overcome by the cable of this invention. A fire retardant communications cable comprises a core which comprises at least one transmission media immediately surrounded by a protective insulation layer made of a fire-retardant thermoplastic material. More specifically, the fire-retardant thermoplastic material used as the insulation layer comprises a mixture of a first inorganic oxide constituent and a second inorganic oxide constituent. The first inorganic oxide constituent is characterized by melting when exposed to temperatures as low as about 350°C whereas the second inorganic oxide constituent begins to crystallize at about 650°C. The layer of fire retardant thermoplastic material is effective when said cable is exposed to temperatures in the range of about 350°C to 1000°C to form a crusty layer which insulates said core from heat energy and minimizes release of smoke and combustible gases. In other words, one embodiment of the present invention modifies the formulation of commonly-used insulation materials so as to provide superior resistance to flame spread and smoke evolution while also providing the necessary electrical performance to make it acceptable for use as the layer of material immediately adjacent the transmission media.
    In an alternative embodiment of the present invention, two layers of thermoplastic material are used to protect each transmission media. In particular, a first layer of commonly used insulative material is applied immediately adjacent the transmission media with a second layer of enhanced insulative material coextruded thereon. In accordance with this embodiment, the second insulative layer has dispersed therein the mixture of inorganic oxides set forth above, and further described and claimed herein. The presence of the oxides in the second layer acts to significantly enhance the fire resistance of the cable without adversely affecting the operational performance of the cable.

    摘要: A method is disclosed for rate allocation within the individual switches of a communications network implementing a rate-based congestion control approach for best-effort traffic. The methodology of the invention centers on a new rate allocation algorithm which performs its allocation functions independently of the number of connections sharing a network link and therefore performs an allocation in Θ(1) time. With that implementation simplicity, the algorithm is particularly advantageous for implementation in ATM switches carrying a large number of virtual channels. The algorithm operates on bandwidth information supplied from the source of a connection in special cells or packet headers, such as ATM Resource Management cells. By storing parameter values for other connections sharing a network link, the algorithm requires a constant number of simple computations for each request from a connection for a bandwidth allocation. The algorithm is asynchronous and distributed in nature and converges to the max-min fairness allocation. G60

    摘要: A method and apparatus for training a text classifier is disclosed. A supervised learning system and an annotation system are operated cooperatively to produce a classification vector which can be used to classify documents with respect to a defined class. The annotation system automatically annotates documents with a degree of relevance annotation to produce machine annotated data. The degree of relevance annotation represents the degree to which the document belongs to the defined class. This machine annotated data is used as input to the supervised learning system. In addition to the machine annotated data, the supervised learning system can also receive manually annotated data and/or a user request. The machine annotated data, along with the manually annotated data and/or the user request, are used by the supervised learning system to produce a classification vector. In one embodiment, the supervised learning system comprises a relevance feedback mechanism. The relevance feedback mechanism is operated cooperatively with the annotation system for multiple iterations until a classification vector of acceptable accuracy is produced. The classification vector produced by the invention is the result of a combination of supervised and unsupervised learning.

    摘要: A mechanically stable self-aligned optical switch having a low insertion loss is achieved by employing two silica substrates (35,40) containing optical waveguide arrays (37). The waveguides within each substrate are arranged in a common plane. It is possible to achieve such silica substrates by cleaving a monolithic silica substrate. In one embodiment, the substrates are disposed on respective flat surfaces of moveable (15) and fixed bases (5) that are aligned in a common plane. The substrates are further positioned with their cleaved edges (39,44) adjacent to and facing one another. In this manner, the waveguides of the cleaved substrates are effectively self aligned in the direction normal to the flat surface of the bases. In operation, the moveable base moves in the direction along the cleaved edges to selectively provide connections between the waveguides in each substrate.
