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.

Abstract: An image reader has a transport passage for transporting an original, a CIS for reading an image on the original transported on the transport passage, and a control member for pressing the transported original against an abutment member disposed at an opposed side of the transport passage at a read position of the CIS. The original does not slide on glass at the read position of the CIS and is moved with the original abutted against the abutment member of a chute on the opposed side, and image data is read in sequence.

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.

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.

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.

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.

In response to a request from a job control section, a resource management section dynamically changes the amount of resources to be allocated to a job at the time of execution of the job, so as to correspond to the priority of the job.
