20110104389	METHOD FOR PATTERNING A SURFACE USING SELECTIVE ADHESION - The invention relates to a method of patterning a layer formed from a fixable material such as photopolymer on a surface in a desired pattern. The method involves coating selected areas of the substrate with an adhesion promoter and subsequently coating the fixable material. The fixable material is then fixed, for instance by curing by exposure to UV radiation. The adhesion promoter is adapted to have a surface energy which is designed to adhere to the substrate or selected areas thereof and also to the fixed material such that fixed material may be easily removed from areas of the substrate not coated with adhesion promoter but retained in areas where the adhesion promoter has bonded to the substrate.	05-05-2011

20090300054	SYSTEM FOR INFERRING DATA STRUCTURES - A system is disclosed for formulating structure descriptions from data. In some embodiments, data arrives with an unknown format. The data may be ad hoc data that is considered semi-structured. Disclosed embodiments analyze chunks of the data to determine tokens. Tokens are analyzed to identify base types and compound types such as structs, unions, and arrays. Descriptions are generated and undergo scoring and rewriting for optimization. The generated descriptions may be fed to a data description language such as Processing Ad Hoc Data System (PADS) and compiled for processing the raw data. In some embodiments, the raw data is parsed, printed, or reformatted using the generated descriptions.	12-03-2009

Through its various components, the cross-border Facilitator creates new markets by generating and facilitating three stages of a cross-border trade transaction: identification, selection and execution. In one embodiment, the Facilitator manages the transaction by: creating a transaction “template” based on transaction information (i.e., HS product code, ISO country code, etc), alerting the buyer to potential problem areas, and updating of important upcoming dates and actions. The Facilitator creates all the required documents, integrates all events, including the service providers, and allows both parties to track the status of the transaction on-line at any time. In one embodiment, the Facilitator receives a search request from a system user, the search request including product and shipping related data. The Facilitator then generates a quote for the transaction and transmitting the quote to the user. The Facilitator receives an indication that the transaction quote has been finalized by the user and effectuates one or more transaction logistics elements based on the product and shipping details included in the finalized quote. The Facilitator then facilitates payment of one or more entities involved in the transaction.	04-02-2009
