摘要： A system, method and program product for rotating a first image in an image buffer such that the resulting, rotated image is substantially free of an aliasing error, i.e., broken lines, stair stepped edges, etc., is dislosed. An algorithm is applied to the first image that uses weighted sums of data points of the first image to create the rotated image. The weighting is based on the skew angle and data point location of the first image. The resulting rotated image also has a reduced data storage space requirement compared to rotated images created by prior art techniques.

摘要： A system and method of imaging a document wherein a watermark is created and applied to the image. The watermark includes identifying information and may include information to determine whether the image has been altered since its creation. In a system where a single document (such as a check) is used to create multiple images (in the case of a check, an image of the front and back may be created in different manners, such as with different resolution or different levels of grey-scale). The use of a single watermark for multiple images of the same check can be used to determine that the multiple images are in fact of a single document and not of different documents, either though mistake or deception. A digitized image of the document is stored and a watermark associated with the document is generated and overlaid on the image to create a watermark on the image of the document for later use and processing.

摘要： A system and method is disclosed wherein a plurality of nodes within an ad hoc wireless network are able to wirelessly communicate with each other. Each node includes a first data array for storing a node identifier used in selecting a clusterhead and a second data array for storing information relating to the node providing the node identifier for selecting the clusterhead to the node. Control logic of each node is configured according to a heuristic wherein the node initially determines a largest and smallest node identifier for each node. The node selects a clusterhead for the node responsive to the largest node identifier and the smallest node identifier using a set of predefined rules. The nodes within the area are then linked with the selected clusterhead.

摘要： An improved erasing structure for performing a programming back operation and a concurrent verify operation subsequent to application of an erasing pulse in an array of multiple bits-per-cell flash EEPROM memory cells is provided. A memory core array (12) includes a plurality of memory cells and an erase verify reference cell array for generating an upper erased state threshold voltage level. A pre-charge circuit (36a) is used to pre-charge all the array bit lines to a predetermined potential prior to a programming back operation. A reference generator circuit (134) is used for generating a reference output voltage corresponding to a lower erased state threshold voltage level. A switching circuit (P1, N1) is used to selectively disconnect a program current source of approximately 5 .mu.A from the selected certain ones of the columns of array bit lines containing the selected memory core cells which have been correctly programmed back. A sense logic circuit (26, 27) continuously compares a potential on one of the selected bit lines and the reference output voltage corresponding to the lower erase threshold voltage level. The sensing logic circuit generates a logic signal which is switched to a low logic level when the potential on the selected bit line falls below the bit line voltage corresponding to the lower erased state threshold voltage level. The switching circuit is responsive to the low logic level for disconnecting the programming current source so as to inhibit further programming back of the selected memory core cells.

摘要： Channel assignment for wireless access networks is directed toward improved overall communication capability of the networks. A network is formed of wireless access points (APs) coupled via wired (and/or wireless) links and enabled to communicate with clients via radio channels of each of the APs. Local information is collected at each of the APs and processed to determine channel assignments according to a Neighbor Impact Metric (NIM) that accounts for one-hop and two-hop neighbors as well as neighbors not part of the network. Optionally, the NIM accounts for traffic load on the APs. The channel assignments are determined either on a centralized resource (such as a server or one of the APs) or via a distributed scheme across the APs. The local information includes how busy a channel is and local operating conditions such as error rate and interference levels.

摘要： Enhanced mesh network performance is provided by computation of a path metric with respect to multi-hop paths between nodes in a mesh network and determination of a path through the mesh network that is optimal according to the path metric. Information is communicated in the mesh network according to the determined path. Nodes in the mesh network are enabled to communicate via one or more wireless links and/or one or more wired links. The path metric optionally includes an effective bandwidth path metric having elements (listed from highest to lowest conceptual priority) including an inverse of a sustainable data rate, a number of wireless links, and a number of wireless and wired links. The sustainable data rate is a measure of communication bandwidth that is deliverable by a path for a period of time. Accounting is made for interference between contiguous wireless links operating on the same channel.
