Abstract: A molecular single electron transistor (MSET) detector device (14) is described that comprises at least one organic molecule (87) connecting a drain electrode (84) and a source electrode (82). In use, said at least one organic molecule (87) provides a quantum confinement region. At least one analyte receptor site (90, 92) is provided in the vicinity of said at least one organic molecule (87) that bind molecules of interest (analytes). A fluid analyser (2) is also described that includes the MSET detector, a pre-concentrator (4) and a fluid gating structure (6). The fluid gating structure (6) is arranged to selectively route fluid from the pre-concentrator (4) to either one of the detector (14) and an exhaust port (12). The pre-concentrator (4), fluid gating structure (6) and detector (14) are each formed as substantially planar layers and arranged in a stack or cube.

Abstract: A buyer agent system is disclosed for assisting purchasers to retrieve data, obtain services, and purchase products on a computer network. One embodiment identifies a purchaser's goal and then uses a knowledge base to create a plan for meeting the determined goal. The system uses an inference engine such as a partial order planner, or a non-monotonic truth maintenance system to create plans. One embodiment of the present invention is an Internet browser plug-in for assisting purchasers in conducting electronic commerce.

Abstract: A dynamic business process management system and method is disclosed for providing using a least commitment planner to better handle the changes and uncertainties that inevitably occur in the real-world. An embodiment of the invention provides a dynamic business process management system using partial-order planning. An additional embodiment of the present invention includes an intent interpreter module that supports the implementation of intelligent decision support functionality in a corporate information management interface.
