  • Asphalt Crack Detection Using Thermography
    , white cracks, and a variety of other problems have presented serious challenges to automated crack identification and detection in this frequency region. The goal here is to test the hypothesis that asphalt cracks cause changes to surface conditions and emissivity leading to perceived temperature
  • Case Study: Crack Detection in Con-rod Bolts
    The problem was that small cracks (bursts and folds) could not be reliably detected using existing inspection technologies. The Resonic ARIS system with the latest opposed twin transducer system was able to reliably detect the smallest "threshold" crack. A sample of "good", "threshold" and "bad
  • Bearing Failure Detection (.pdf)
    Frequency. balance alignment forces. · HF-sonic/ultra sonic. energy detects surface. roughness. · CF- shock wave impact. ratios detect surface. crack spiking defects. · KF-Kurtosis detects. serious fatigue cracks. and spalling defects. · ED-short duration. ball/race impacting. Acceleration time
  • The Detection of Stud Line Cracking in Metal Stud Walls (.pdf)
    the foam-metal interface within the. channel of the stud. The implication of an un-repaired crack may be that air and moisture vapor can enter the building. envelope via the crack minimizing the intended performance of the spray foam. At the Center for Surface Transportation Technology's (CSTT
  • Tiny sensors keep big aircraft healthy
    , according to team leader Dennis Roach. The sensors were tested in a lab and validated on three commercial aircraft. Boeing recently added the in situ, or permanently-mounted, crack-detection CVM sensor to its Common Methods NDI Manual after a two-year validation program. Sandia is also working
  • Tin foils RFID thieves
    ignition keys and wireless-payment tags. The stolen information is then used to crack the chip's secret, encoded cryptographic key, giving thieves unauthorized access to whatever the key protects. It turns out the 40-bit encryption key used in the transponder tags is not strong enough to prevent
  • Developers
    applicator or swirl chamber after the application of penetrant to develop or enhance detection of the surface flaw. The fluorescent powder sticks to the penetrant remaining in a flaw or surface crack after cleaning.  With aqueous-based developer methods, the powders are suspended in a liquid
  • Seeing Is Believing
    analysis such as finding a fine crack in a glass beer bottle. Vision systems are increasingly deployed to guide robots in performing assembly tasks. In addition, they facilitate necessary processes such as SPC and material planning by reading date and lot codes, and bar codes. Cosmetic defects
