Next-Generation Custom-Fit Reusable Respiratory Protective Device with Continuous Fit Monitoring. S Park, Y Tian, M Bergman, Dr. Ziqing Zhuang, J Pollard, S Jayaraman.

As the first step in customizing the prototype, a set of 21 facial anthropometric landmarks and 15 dimensions was selected for the design. The faces of three members of the research team were scanned using a 3dMD digital scanning system. From these scans, algorithms were developed to create digital representations of the contours of the RPD frame.

NIOSH’s “Respirator Fit Evaluation” Challenge… A Phase 1 Winner. S Jayaraman, S Park.

Their innovation device is customized to the individual’s facial profile, continuously monitors the fit unobtrusively, and when there is a change in the fit during use, which could lead to a faceseal leakage, alerts the user through an App on the smartphone thereby ensuring the user’s safety.

Effect of alar base cinch suture based on anatomic landmarks on the morphology of nasolabial region in patients after orthognathic surgery.

This modified alar base cinch suture is more favorable for the postoperative nasal coordination and nasolabial morphology in patients who need mild to moderate maxillary advancement, and it has certain advantages in operability and objective accuracy.

Initial Steps towards a Multilevel Functional Principal Components Analysis Model of Dynamical Shape Changes. DJJ Farnell, P Claes.

Multilevel PCA (mPCA) has been used by us to analyze 3D facial shapes obtained from 3D facial scans; note that two-level multilevel PCA (mPCA) is equivalent to bgPCA. mPCA has been used previously to investigate changes by ethnicity and sex, facial shape changes in adolescents due to age, and the effects of maternal smoking and alcohol consumption on the facial shape of English adolescents.
