  • Patent number: 9275019
    Abstract: System and method for performing Unicode matching for comparing and merging similar data objects having Unicode strings that are equivalent yet not exact matches. Unicode characters are characterized by number of strokes, stroke order, radicals, geometry, phonemes in association with input method editor and keyboard characteristics such as location of a character on an IME or keyboard (or number of GUI interface interactions used in entering the character, e.g., via tapping where “a” on a mobile device keyboard takes 1 tap of a key, “b” takes 2 taps). These characteristics associated with code points and IME's/keyboards are utilized to create subdomains for matching and determining “distance” to other Unicode code points (e.g., number of keyboard keys away). Allows for determining whether close, yet incorrect data entry may have taken place. Enables merging of duplicate data objects into master data object where minor differences or spelling errors introduce actually represent duplicate data.

  • Patent number: 8331621
    Abstract: A toll violation enforcement system that contains a capture unit that receives a trigger signal and takes vehicle images of passing vehicles. A lighting unit configured to operate continuously is provided to establish a major lighting source incident on the vehicle. A processing unit is provided that processes the vehicle image and controls the settings employed by the capture unit. The processing unit preferably contains a plate location module for extracting an original resolution license plate area image from a first vehicle image; an exposure control module for controlling the exposure setting on the capture unit to provide consistent intensity of the license plate area; a resolution reset module for changing the image resolution for a second vehicle image; an image enhancement module for brightening pixels of the second vehicle image; and an image compression module for compressing the license plate area image and second vehicle image to a predetermined format.

  • Patent number: 8200673
    Abstract: A system and method for on-demand indexing in a data management system is described. An index is generated when it is requested, such as when a database operation requires access to the index. If the index is loaded in memory, the index is retrieved from memory. Otherwise, the index is generated on-demand. A priority configuration identifies at least one priority index which is generated and loaded in memory. The priority configuration can identify priority indexes either directly or indirectly, such as by a threshold parameter.
