Abstract: Devices are provided for remote environmental and atmospheric testing that can be deployed without personnel entering a potentially dangerous area. The device can detect and automatically analyze biological and chemical agents and then automatically report if any of these agents are present without the intervention of public safety or military personnel. During sample collection and analysis, the device deploys a sample-collecting pad, tape, or filter which is then retracted with captured samples (liquid or solid) obtained from either surfaces or as aerosols from the air. The captured samples may be retracted into an enclosed vessel which will then extract the sample off of the pad, tape, or filter into a liquid carrier, and this liquid carrier is delivered to a downstream process for further analysis.

Abstract: A device and method used to log images of target objects with ultrasound transducers. The object may be a fluid-carrying tubular, such as a pipeline. The transducers operate as phased arrays, insonifying areas of the target object with a plane wave and then storing the reflected signals.
