Method and apparatus for automatic generation of information system user interfaces
InactiveUS7334216B2Promote rapid developmentPromote modelDigital data information retrievalMultiprogramming arrangementsOperational systemPattern language
A method and apparatus for the specification and automatic generation of user interfaces of information system (computer programs) is provided. The method is based in pattern language to specify requirements in an un-ambiguous mode and with precise semantics. The pattern language allows a user interface model to be composed using elements of the pattern language (computer objects in the object oriented programming style) which fully specify the desired user interface. The semantics of the objects in the user interface model have one and only one definition such that user interface model can be validated in a validation process. The validation process eliminates bugs in the final computer program code which is automatically produced from the user interface model. A model (metamodel), an editor tool (computer program) implementing the model for creating specifications of the user interface model, DTD specification, code generators, and other artifacts are depicted and described here for obtaining such user interfaces for different platforms (computers and operating systems) and different programming languages without manual coding of the computer code to implement the user interface. The software obtained is ready to run and it is able to communicate with a business server component using a standardized Application Programmatic Interface (API).

Plural nodes are arranged at predetermined initial positions, and feature values at plural sampling points around each node are obtained as a node feature value of each corresponding node. An error estimator indicating displacement between the current position of each node and the position of corresponding feature point is obtained based on correlation information on a difference between the node feature value obtained in a state in which the plural nodes are arranged at correct positions of the corresponding feature points and the node feature value obtained in a state in which the plural nodes are arranged at wrong positions of the corresponding feature points in a learning image, correlation information on a difference between the correct position and the wrong position, and a node feature value of each node. The position of each feature point is estimated in an input image based on the error estimator and the current position of each node.

Biodiesel purification by a continuous regenerable adsorbent process
ActiveUS20090199460A1Reduced stabilityLarge amount of removalOrganic anion exchangersLoose filtering material filtersFiltrationSorbent
A quick, economical and environmentally friendly, “green”, process for the continuous purification of biodiesel (fatty acid alkyl esters (FAAE)) is described using a powdered, granulated or extruded adsorbent. The adsorbent is contained in a column system and is regenerated for reuse multiple times. The process employs an adsorbent such as, but not limited to, carbon, silica, clay, zeolite or a metal silicate contained in a column to remove the impurities from fatty acid alkyl esters (FAAE) or crude biodiesel in a continuous process. The process utilizes the adsorbent column system for the purification of biodiesel, rather than water or filtration, to remove soaps and other impurities entrained in a crude biodiesel. The crude biodiesel is contacted with an adsorbent packed into a column, or multiple columns in series, for a sufficient amount of time to remove impurities such as, but not limited to, soaps, metals, free glycerin, sterol glucosides and many of the other impurities that reduce the stability of biodiesel. The resulting finished biodiesel exiting the column(s) is ready for the methanol recovery process. Once the adsorbent no longer removes the desired amount of impurities, it is regenerated for reuse. The solvent used for the regeneration process is reclaimed and reused by recycling it back to the transesterification reaction.
