Abstract: Systems and methods are described for procedurally-based decision support using ontology-based classification of database records. The procedural decision support can facilitate extraction of contextually relevant data from a database. The data may be formatted for compatibility with a knowledge-based data library using one or more scripts and populated in the library as an entity. Classification of the entity can be reasoned using the available data. One or more classifications of the entity may be returned to the procedural decision support to facilitate computation of a recommendation.

Abstract: A piezo-electric actuator operable in a fluid. The actuator has a piezo-electric element having one or more layers of piezo-electric material and electrodes adjacent to the piezo-electric material, the electrodes being coupled to electrical leads. A conductive layer surrounds the piezo-electric element, serving as a Faraday cage for shielding the fluid from effects due to electric fields within the conductive layer. A seal substantially impermeable to the fluid surrounds the piezo-electric element.
