The document summarizes tests of a microphone prototype and LabView algorithms for detecting human errors. It outlines tasks from a previous meeting, describes the microphone prototype, and reports on LabView results analyzing audio files to detect differences between files representing correct and incorrect settings. Tests were conducted in simulation mode to verify files were loaded correctly and differences detected between non-identical images and audio files. Results are presented for various component errors detected by analyzing changes in audio signals.

Outline of the review ? Update on tasks from the previous meeting ? Microphone prototype ? LabView Results for detecting methods/algorithms for audio files
Update on labView ? Need: Vision and Motion package to analyze the images ? Issue: ¨CThe Vision and Motion programming/function package is missing or not available for the Labview 2014 and NI myRio software ? This issue is resolved
Image test ? Simulation mode ¨C Make sure image files are loaded into the workspace without any issues. ¨C Make sure a correct file is loaded ¨C Plot histogram of the image ¨C Verify that the histogram value is correct. ¨C Positive test: load two image files which have 2 different images and verify that the test results show the difference. ¨C Negative test: load two image files which have 2 similar images and verify that the test results show the same thing or match.
Labview results for comparing two images which are identical
LabView results for comparing two images which are not identical
LabView results for comparing two images which are not identical
Audio test ? Simulation mode ¨C Make sure audio files are loaded into the workspace without any issues. ¨C Plot and listen to audio files; make sure a correct file is loaded. ¨C Verify that the FFT value is correct. ¨C Positive test: load two audio files which have 2 different signals and verify that the test results show the difference. ¨C Negative test: load two audio files which have 2 similar signals and verify that the test result show the same thing or match.
Microphone prototype for correct setting
LabView results for comparing two audio files which are identical
Microphone prototype for hex pin not popped out
Result of hex pin not popped out after executing the device for 1 min
LabView results for comparing two audio files (hex pin) which are not identical
Microphone prototype for upper arm not correctly set
LabView results for comparing two audio files (upper arm) which are not identical
Microphone prototype for upper arm not correctly set
LabView results for comparing two audio files (upper arm) which are not identical
Microphone prototype for lower bearing not correctly set
LabView results for comparing two audio files (lower bearing) which are not identical
