An air leak detection system for chest tube collection systems includes a light emitting element, such as an LED, and a photodetector that can detect reflected light emission generated by the light emitting element. The air leak detection system can include a securement component, such as a transparent clip or adhesive, so that the air leak detection system is compatible with any conventional chest tube collection system. In certain embodiments, the light emitting element is positioned closer to the bottom portion of the water seal tube than the photodetector. In certain embodiments, the photodetector is positioned closer to a bottom of the water seal chamber than the light emitting element. In certain embodiments, the air leak detection system is part of a chest tube drainage system. A method of detecting an air leak in a chest tube collection system is also disclosed.

A thermal imaging system for use in maintaining a turbine assembly includes a case, a single pixel detector positioned within the case, at least one optical transportation device, and a prism. The optical transportation device is coupled to the case and configured to direct electromagnetic radiation to the single pixel detector. The prism is coupled to the optical transportation device and configured to direct electromagnetic radiation into the optical transportation device and to the single pixel detector. At least the prism and the optical transportation device are inserted into the turbine assembly and the single pixel detector acquires images of the turbine assembly.

Disclosed is a method for detecting a blowout in an irrigation pipe being formed by an extrusion manufacturing process. The irrigation pipe is extruded. Further a positive air pressure inside the irrigation pipe may be created by circulating air through the irrigation pipe during the extrusion manufacturing process. The irrigation pipe with positive air pressure is then fed into a tank, wherein the tank comprises a coolant liquid. Further at least one air bubble is trapped at a surface of the tank.
