Competing Interests

I have read the journal's policy and have the following conflicts: patent pending on the technique (TFF, AGY, RCM). We would like to declare that there is a patent pending on the technique (Fiber Optic Flow and Oxygenation Monitoring Using Diffuse Correlation and Reflectance, TFF, AGY, RCM. Provisional Application no. 611,570,349, Filed on Dec 14, 2012). This does not alter our adherence to all the PLOS ONE policies on sharing data and materials.
