Abstract: An exemplary embodiment of the present invention is directed to a system, method and computer program product for providing an object recognition blackboard system architecture. The system for recognizing objects in content can include: a blackboard comprising a plurality of experts, and data comprising original input data and data created by processing of any of the plurality of experts, and a controller operative to control the experts; a belief model, coupled to the controller, comprising a set of beliefs and probabilities associated with each belief of the set of beliefs; a belief network, coupled to the controller; and a relations subsystem, coupled to the controller.

Abstract: A field electron emission material is created by applying a silica precursor to graphite particles (11); processing the silica precursor to produce amorphous silica (12) which is doped and/or is heavily defective, and disposing the graphite particles (11) upon an electrically conductive surface (14) of a substrate (13) such that they are at least partially coated with the amorphous silica (12).

Abstract: To create a field electron emission material, there is printed upon a substrate (1501) an ink (1503) comprising a major component of fluid vehicle; a first minor component of electrically insulating material, either on its own or provided within a precursor therefor; and a second minor component of electrically conductive particles (1504). The printed ink is then treated to expel the major component and create the field electron emission material from the minor components on the substrate. The electrically conductive particles may be omitted, to print a solid, electrically insulating layer in a field emission device.
