  • Publication number: 20040008747
    Abstract: A method of fabricating a surface emitting semiconductor laser includes the following steps. A first laminate of semiconductor layers and a second laminate of semiconductor layers are formed on a substrate. The first laminate includes a first reflection mirror layer of a first conduction type, an active region, a III-V semiconductor layer containing Al, and a second reflection mirror layer of a second conduction type, the second laminate being used for monitoring and having an oxidizable region. The first and second laminates are etched so as to form mesas on the substrate in which side surface of the III-V semiconductor layer contained in the first laminate is exposed. Oxidization of the III-V semiconductor layer from the side surface is started at an oxidization rate.

  • Publication number: 20040010492
    Abstract: This invention describes methods and systems for tasking nodes in a distributed ad hoc network. A node is selected to participate in a data gathering or a routing task based on its potential contribution to information gain and the cost associated with performing the task such as communication bandwidth usage. This invention describes methods and systems for implementing various selection strategies at each node, using local knowledge about the network. For resource-limited sensor networks, the information-driven data gathering and routing strategies significantly improve the scalability and quality of sensing systems, while minimizing resource cost.

  • Patent number: 6678425
    Abstract: An angular orientation of a lattice image pattern is found by forming a composite image of superimposed portions of a lattice image by aligning centroids of a lattice element in each portion, and determining a lattice axis from a line fit through centroids of lattice elements in the composite image. The composite image is formed by selecting a seed pixel, finding a local minimum near the seed pixel and then finding a centroid based on the local minimum. From the centroid, it is determined whether the glyph centroid has sufficient contrast to be included in the composite image. The composite image is formed by superimposing subsamples of the lattice image based on glyph centroids. The composite image is then analyzed to determine a lattice axis through centroids in the composite image, and determining a quadrant image based on the lattice axis.

  • Patent number: 6678415
    Abstract: A text recognition system represents the decoded message of a document image as a path through an image network. A method for integrating a language model into the network selectively expands the network to accommodate the language model only for certain ones of the paths in the network, effectively managing the memory storage requirements and computational complexities of integrating the language model efficiently into the network. The language model generates probability distributions indicating the probability of a certain character occurring in a string, given one or more previous characters in the string. Selectively expanding the image network is achieved by initially using upper bounds on the language model probabilities on the branches of an unexpanded image network. A best path search operation is then performed to determine an estimated best path through the image network using these upper bound scores.

  • Patent number: 6678493
    Abstract: The specification discloses an image forming apparatus which forms a visual image on a belt transfer member by at least one of image forming units and transfers the formed visual image onto a recording medium with the aid of the belt transfer member. In the image forming apparatus, the belt transfer member includes an endless belt wound on a plurality of tension rolls. A bending member, which bends the endless belt toward the inside of a tangential line connecting points on the outer circumferences of a couple of tension rolls, and locates the bent endless belt inside the tangential line, is additionally provided outside the endless belt located between at least the couple of adjacent tension rolls. An image forming unit may be additionally provided within an outside bending concave region of the endless belt, which is bent by the bending member and the tension rolls adjacent to the bending member.

  • Patent number: 6676106
    Abstract: A thin laminate film structure comprises a first metallic lamina formed on a surface of a first dielectric lamina and a third lamina formed on a surface of the first metallic lamina opposite the first dielectric lamina. Electrical and mechanical properties of the thin laminate film structure may be determined and/or optimized separately. The first metallic lamina and the first dielectric lamina may comprise aluminized mylar. The third lamina may or may not be made of a dielectric material. The thin laminate film structure may further comprise a second metallic lamina formed on a surface of the third lamina opposite the first metallic lamina and a second dielectric lamina formed on a surface of the second metallic lamina opposite the third lamina. In such a case, the thin laminate film structure allows dual-direction actuation of electrostatically and/or magnetically driven devices, such as microdevice valves, in which the thin laminate film structure may be employed.

  • Patent number: 6678677
    Abstract: An information retrieval apparatus retrieves information from databases comprising internal representations of documents. Syntactic relations between terms of the query are extracted and an internal representation of the query is created based on the terms of the query and the extracted syntactic relations. New terms are appended to a semantic lattice if the query includes terms not included in the semantic lattice. The query is projected onto the documents in the database by comparing the internal representation and terms of the query to the internal representations and terms of the documents using the semantic lattice for comparing the terms and a similarity is computed between the query and each document. The documents are ranked according to their computed similarities and are output as retrieved documents according to the established rank order.
