  • Patent number: 6275866
    Abstract: Software components such as objects, applications and computational blocks are linked through a data flow manager and an interface that facilitate data exchange between the components. The interface defines a communication protocol. Components that comply with the protocol can share data, even if such components are associated with unrelated applications. Non-compliant components can be paired with translation objects or controlled by scripts to allow such non-compliant components to be linked to compliant components for data sharing. The data flow manager controls data exchange by determining which components are prepared to share data, and then prompting only prepared components to share data. Data exchange is executed in discrete steps.

  • Patent number: 6275859
    Abstract: To authenticate and authorize prospective members in a reliable multicast data distribution setup, the prospective members contact a central authority to obtain a “participation certificate” for the multicast session. The central authority authenticates each node and issues a digitally signed certificate to the node. Each certificate contains information specifying the manner in which the respective node is authorized to participate in the multicast session in addition to the respective node's public key. The nodes exchange their participation certificates with each other during session-establishment dialog to prove their identities and their authorization to participate. Each node verifies the rights of other nodes based on authorization information contained in the participation certificate received from the other node. Thus, a node is allowed to participate as a repair node only if it presents a participation certificate authorizing it to do so.

  • Patent number: 6272310
    Abstract: A toner fuser system suitable for producing high quality color transparencies is provided. The fuser system includes a media conditioning assembly located directly downstream of a fuser assembly, which may be a roll fuser or an instant-on belt fuser. The conditioner assembly includes a convective heat source, a heating zone, and a convective circulation path past the heat source and the heating zone to provide convective heat transfer to a transparency in the heating zone. A transparency (or other media) with toner to be fused travels on a media path first through the fuser assembly and then through the heating zone of the conditioner assembly. The fuser assembly causes toner to adhere to the transparency just well enough to allow the transparency to pass into the conditioner. In the conditioner, the toner is reheated, thereby causing the surface of the toner to reflow into a smooth, glossy, and uniform surface that increases light transmission efficiency of color transparencies.

  • Patent number: 6272247
    Abstract: A system for digital image recognition which combines sparse correlation with image pyramiding to reduce the number of pixels used in correlation provides effective recognition of a reference image template without exhaustive correlation of all pixels in the reference image template. An optimal sparse pixel set is selected from the pixels of the reference image template by correlating the reference image template against a search image scene which is to be searched. Such a sparse pixel set includes those pixels which are optimal in defining the correlation sensitive features of the reference image template. By terminating the accumulation of sparse pixels at an optimal point, performance is maximized without compromising accuracy of recognition. The resultant optimal sparse pixel set is then correlated against the pixels in the search image scene through a series of transformations to find a match of the reference image template within the search image scene.

  • Patent number: 6269085
    Abstract: A method and system for pruning slow multicast group members in a multicast group that includes a sending node and member nodes. The sending node and selected ones of the other nodes comprise repair heads of a repair tree. Each repair head has at least one child. Each of the member nodes generates a slowness metric. Each member node repair head aggregates its own slowness metric with the slowness metrics of their respective children in the tree along with a subtree flag that indicates whether the respective slowness metric is due to the reporting node or a node downstream of the reporting node. The member node repair heads propagates the largest of the aggregated slowness metrics upstream along with a subtree flag associated with the propagated slowness metric. Via this process the sending node receives the largest slowness metrics generated in respective branches of the repair tree along with corresponding subtree flags associated with the respective metrics.

  • Patent number: 6265851
    Abstract: An ultracapacitor power supply for an electric vehicle is provided which employs an ultracapacitor as the primary power source and a battery as a supplemental power source. This vehicle is particularly effective in power-rail system having gaps in the power-rail or in non-power rail systems having recharging stations positioned along the track The ultracapacitor recharges quickly upon vehicle passage over a live power rail or entry into a recharging station. Optimum performance is achieved when the capacitor is allowed to fully recharge. The battery need only provide power when the ultracapacitor has been discharged or during acceleration or other periods of peak power consumption, thereby reducing the number of battery recharges required during any given operational period.
