Abstract: There is disclosed a method of operating a communications network having a plurality of selfish users. Each selfish user may send messages to a destination node with the messages being forwarded through intermediate nodes of a mesh network.

Abstract: A method, system and computer program product are provided for automating the task of data collection and reduction for highway vehicle detector testing. To evaluate the performance of each detector under test, a set of detection data is accumulated concurrently from each of the detectors. This data consists, at a minimum, of the time of arrival of each vehicle as reported by each detector and a digitized video image of the vehicle at the position-compensated time of detection. The data reduction process allows for applying weighting coefficients to each detection result in the formation of a consensus. These coefficients may be either fixed or adaptively adjusted based upon the learned accuracy of each detector under test. A ground truth reference data set is then generated using the weighted consensus determined from the data generated by all detectors under test.

Display of the pre-selected media content is then suspended when the document processing signal indicates that the document processing device is active. User-specified media data content is then generated on the display of the user interface when the received document processing signal corresponds to active status of the associated document processing device.
