Abstract: A fluid compressor includes a housing; a compression chamber within the housing; a motor; a shaft that is rotated by the motor; and a piston assembly including at least two pistons directly connected to each other without any connecting rods. The piston assembly performs a reciprocating motion when acted on by the shaft such that the at least two pistons move within the compression chamber to compress a fluid.

Abstract: Presented herein are systems and methods to automatically and periodically retrieve clinical trial data from an EDC source, process the data to transform it from its initial representation as retrieved from the EDC source into table-based format, and store the resultant transformed data in an intermediate data storage layer for access by stakeholders. Accordingly, instead of accessing source data, such as EDC ODM-XML data directly from an EDC source, a stakeholder may retrieve clinical trial data from the transformed data stored in the data storage layer. The systems and methods provide transformed data that better serves the needs of stakeholders during a clinical trial.
