Abstract: An apparatus and method for training a search engine generates synthetic search arguments and target information that are provided to the search engine as training. A search argument simulator ingests product information and historical interaction data, determines relevant descriptors, creates compound descriptors, and creates candidate search arguments. A trainer checks the candidates against historical search arguments, identifies similar search arguments and determines likely search arguments that are used for training. An evaluator monitors search engine responses and triggers retraining of the search engine.

Abstract: Dampening of unwanted resonant modes in a conductive enclosure for microwave circuitry carried on a conductive ground plane is provided by interrupting the ground plane at one or more locations about the microwave circuitry and providing electical resistance by either a resistive film or resistor spanning the one or more interruptions in the ground plane to thereby dampen one or more dominant resonant moded in the enclosure. One or more interruptions or openings for electrical resistance may be preferably located at locations of maximum current flow of the one or more dominant resonant modes excited by the operation of the microwave circuit, or may comprise a single space or gap provided in the ground plane surrounding the microwave circuitry with a plurality of resistors located about the circuitry to dampen the dominant resonant modes. The electrical resistance for dampening can be calculated with the computer program of Appendix 1.
