Abstract: A license plate recognition process is described that includes automated image analysis integrated with human review and a definition of a plate grammar of license plate visual elements that are required to prepare a database search index that enables selection of a particular license plate, from a known population of all possible license plates issued for each and every jurisdiction of interest. The plate grammar includes visual elements that may be searched by both automated image analysis and by a human reviewer. The process includes creation of a question that guides a human reviewer into providing required information regarding a selected plate grammar element that is not identified by computerized image analysis. Integration of a manual review process within an automated process as opposed to manual review solely at a failed completion of the automated process is included.

Abstract: A digital camera control system that requires no light sensors is described. The control system relies on modeled external environmental geophysical solar parameters, geometric relationships between the object to be imaged and surrounding potentially shadowing objects, the material properties of the object to be imaged such as reflectivity are combined to produce the estimated irradiance on a camera sensor for the particular time of day, date and geometric relationship between the object and the sun. The calculated irradiance on the image sensor for the background of the object of interest and a feature to be recognized provide a contrast. The signal to noise requirements for the feature recognition are used to determine a minimum required contrast transfer function for the sensor. Control parameters for the sensor are then determined to meet the minimum contrast requirements.

Abstract: A license plate recognition and image review system and processes are described. The system includes grouping of images that are determined to be of the same vehicle, using an image encoded database such that verification of a license plate read is done through comparison of images of the actual vehicle to images from the encoded database and testing of the accuracy of a manual review process by interspersing previously identified images with real images being reviewed in a batch process.

Abstract: A tank for containing a fluid, such as fuel, oil or gas within a chamber. The walls of the chamber are partially defined by a rigid structure having an opening; and partially defined by an elastomeric diaphragm which is attached around its periphery to the rigid structure and covers the opening in the rigid structure. An attachment frame engages the diaphragm and the rigid structure, and extends around the periphery of the diaphragm. The attachment frame has a first portion which engages the diaphragm, and a second portion which is positioned outside an outer edge of the diaphragm and attached to the rigid structure.

Abstract: Data for inclusion in a probable cause field of a telecommunications network alarm indication message is structured to comprise first and second delimited data elements respectively indicating first and second predetermined (ie standardized) probable cause codes, the first and second predetermined probable cause codes relating to one or more characteristics of an event occurring or having occurred in a telecommunications network. Methods, apparatus and computer programs for generating and for processing such data is provided as well as signals representing such data.
