Abstract: Efficient differencing and update mechanisms operate directly on the native representation of the data. No irrelevant differences are introduced by the process. The difference reports generated are stated in terms of the basic operations that can be performed on a data tree, thus requiring no additional interpretation, and making it amenable to direct human inspection and understanding. This mechanism can become a central part of any version management system.

Abstract: The disclosure includes a computational system (110) that implements a method for controlling operation of report production facilities. The system (110) is particularly suited to efficiently operating a facility that prints mail pieces and inserts the mail pieces in envelopes for delivery by the U.S. Postal Service. In one implementation, the system (110) includes a main processor (112) that receives constituent data and sequentially stores the data in report recipient files (116). The main processor (112) is utilized to process the stored data to create relational database files (118, 120). The database files (118, 120) include index fields which facilitate tracking and sorting of the data based in part upon postal rates, report lengths, and other distribution and production criteria. The main processor (112) may then be operated to create report output files (160) to be used by a report production facility (160) in printing and inserting the mail pieces.

Abstract: A system and method for removing a file from a system is disclosed. The system includes a storage device and a virtual storage. The file has associated metadata that indicates a location of the file on the storage device. A first copy of the associated metadata resides on the virtual storage. A second copy of the associated metadata resides on the storage device. The system and method include marking the file as removed and updating the second copy of the associated metadata substantially immediately if the system is to run out of space on the storage device and a next scheduled update of the second copy of the associated metadata has not occurred. The system and method further include indicating that the location is available for storing data substantially immediately if the system is to run out of space on the storage device and the next scheduled update has not occurred.

Abstract: A method and an apparatus are provided for combining spatial and temporal filtering for blood speckle reduction in high frequency ultrasound images wherein a sequence of image frames is processed to produce a binary mask. In this mask, a first value is assigned to regions of identified blood speckles and a second value is assigned to regions of the remainder. The images are then modulated with the mask, i.e., by applying different filtering techniques to assigned blood regions and assigned nonblood (i.e., tissue) regions, the filtering techniques having been selected to optimize images for the type of feature to be highlighted based on differences in frequency sensitivity between blood and tissue. The images are preferably in polar coordinate format. The degree of blood speckle suppression can be determined based on the actual values of the pixels at the same spatial location in given frames.

Abstract: A digital data encode system for inserting water mark data into digital data signals having a series of field data by use of a water mark data inserting device, the digital data encode system has a field judging unit dividing the digital data signals by a predetermined reference, a water mark data selection output unit for selecting proper one of a plurality of different water mark data prepared correspondingly to the division according to the judgment result of the field judging unit, and a water mark data inserting device for inserting the water mark data supplied from the water mark data selection output unit into the digital data signals.
