The systems and methods described herein related generally to a device that enables the directional control of flow through an anatomical tract of the body. More particularly, the device described herein includes a valve from a plurality of projections. In some implementations, the projections are configured as flaps, posts, or any combination thereof. In some implementations, the device is implanted into a patient's esophagus to prevent gastroesophageal reflux disease. The plurality of projections allow flow into a patient's stomach while substantially preventing a backflow of undesired fluids from the patient's stomach to the patient's esophagus.

Implantable device for directional control of flow within the anatomic tracts of the body

An in-line loss-on-ignition measurement system includes an on-site extractor subsystem configured to collect fuel or a combustion by-product from a hydrocarbon fuel burning plant. An on-site analyzer is configured to receive the collected matter from the extractor subsystem and configured to weigh the collected matter, burn the collected matter, and weight the collected matter again. A controller is responsive to the analyzer and is configured to determine the loss-on-ignition data for the plant based on the weight of the collected matter before and after it is burned in the analyzer.
