NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed new software that enables users of critical inspections systems to validate the capability of the inspection system. Traditionally, inspection systems are validated using various methodologies to determine probability of detection (POD). One widely accepted metric of an adequate inspection system is that there is 95% confidence that the POD is greater than 90% (90/95 POD). Directed Design of Experiments for Probability of Detection (DOEPOD) is a user- friendly software package that enables detailed analysis of 90/95 POD or at any specified confidence level. Although it was designed to validate the capability of inspection systems to find fracture-critical flaws in materials, DOEPOD can be applied to systems to locate any type of flaw as well as to validate the detection capability of personnel. DOEPOD can also be employed as the core of an NDE system and provide accurate on-demand validation of the inspection system. The DOEPOD software package can validate the capability of inspection systems to find fracture-critical flaws in materials, components, and systems, and for qualifying personnel. DOEPOD provides an accurate methodology that yields observed POD and confidence bounds for both Hit/Miss and signal amplitude testing. The software uses the concept of Point Estimate Probability of a Hit (POH) at any flaw size. POH defines the number of hits observed per set of specimens exhibiting flaws of similar characteristics. The estimated POH determined by DOEPOD at any selected flaw size is a measured or observed quantitative value between zero and one, and knowledge of the estimated POH yields a quantitative measure of the lower confidence bound. In DOEPOD, flaw size is referred to as class length. Flaws are defined as digital, analog, diameter, volume, length, depth, color intensity, grey scale, or by a combination of criteria such as total mass. DOEPOD incorporates these features into a user-friendly software that is easily integratable into any NDE. Today, almost universally, NDE systems are validated by predictive methods, which do not follow a single standard and vary widely in their results. DOEPOD provides an advance in inspection system validation because the software can prove that an inspection system is capable of finding flaws without relying on predictive math models. The software is not limited to inspection data, and may be applied to determine Probability of Success (POS) for commercial and military logistics, industrial engineering, consumer product acceptance, education testing levels, and more.
