Abstract: Programming of the input and output paper handling setup of a high speed reprographic system can adversely affect the throughput of the system. A method or system includes a control system that examines the proposed setup and then determine if any of these options results in a loss of throughput. If such losses are detected and exceed a predetermined threshold, the operator of the device will be informed and given the opportunity to change the setup to reduce the throughput loss.

Abstract: A control system and method of predicting how a machine will respond to occasional or periodic service, and adjusting the machine accordingly to account for the change in machine behavior due to the service, mitigates transients in machine performance. A prediction of the service effect is fed forward to the existing control system just prior to the occurrence of service in order to compensate for the service effect. This prediction is continually updated and refined using subsequent measurements of the effect of service on machine performance. More specifically, a controller monitors the process output variables indicative of the machine performance and adjusts machine inputs to achieve a desired level of machine performance. The controller monitors the process output variables indicative of the machine performance prior to, during, and immediately after the service and adjusts the machine inputs to compensate for the transients.

Abstract: A pattern recognition method and apparatus decrease the amount of computation for pattern recognition and adapts flexibly to an increase and a change in learning samples. Learning is made beforehand on base vectors in a subspace of each category and a kernel function. Pattern data to be recognized is input, and projection of an input pattern to a nonlinear subspace of each category is decided. Based on the decided projection, a Euclidean distance or an evaluation value related to each category is calculated from the property of the kernel function, and is compared with a threshold value. If a category for which the evaluation value is below the threshold value exists, a category for which the evaluation value is the smallest is output as a recognition result. If there is no category for which the evaluation value is below the threshold value, a teaching signal is input for additional learning.

The light-emitting element, the polymeric optical waveguide film and the monitoring light-receiving element are aligned with each other so that the light emitted from the light-emitting element is reflected by the optical path changing mirror surface to be guided through the core and part of the light emitted from the light-emitting element is received by the monitoring light-receiving element via the guided light leakage portion.

Abstract: Demographic information of an Internet user is predicted based on an analysis of accessed web pages. Web pages accessed by the Internet user are detected and mapped to a user path vector which is converted to a normalized weighted user path vector. A centroid vector identifies web page access patterns of users with a shared user profile attribute. The user profile attribute is assigned to the Internet user based on a comparison of the vectors. Bias values are also assigned to a set of web pages and a user profile attribute can be predicted for an Internet user based on the bias values of web pages accessed by the user. User attributes can also be predicted based on the results of an expectation maximization process. Demographic information can be predicted based on the combined results of a vector comparison, bias determination, or expectation maximization process.

Abstract: A method for forming a gap (16) of a width (d) which meets selected tolerance limits includes forming sidewalls (80, 82) in a microstructure, the sidewalls defining a gap (16) therebetween. The gap has a width defined between the sidewalls. The width of the gap between the sidewalls is determined. Where the determined width of the gap is below the selected tolerance limits for the width of the gap, the sidewalls are consumed to form a gap which meets the selected tolerance limits. The gap may be incorporated in a waveguide device (10) of a microswitch (100) and selectively connect input and output waveguides (130, 132).

Abstract: The polarization instability inherent in laterally-oxidized VCSELs may be mitigated by employing an appropriately-shaped device aperture, a misoriented substrate, one or more cavities or employing the shaped device aperture together with a misoriented substrate and/or cavities. The laterally-oxidized VCSELs are able to operate in a single polarization mode throughout the entire light output power versus intensity curve. Combining the use of misoriented substrates with a device design that has an asymmetric aperture that reinforces the polarization mode favored by the substrate further improves polarization selectivity. Other device designs, however, can also be combined with substrate misorientation to strengthen polarization selectivity.

Abstract: Using a document scanner or other image input device of an image or document processing system to periodically scan or image printed test images from a plurality of marking engines replaces internal sensors as a feedback means in image quality control. For example, image lightness (L*) is controlled by periodically printing mid-tone test patches, scanning the printed test patches with a main job document scanner and analyzing the scanned image to determine updated marking engine actuator set points. For instance, ROS exposure and/or scorotron grid voltages are adjusted to maintain image lightness consistency between marking engines.

Job status information is received concerning the output job request forwarded to the output device. The electronic status notification message is prepared using static and dynamic data concerning the job status information of the output job request and the similarity data of the document archived in the document repository.
