Ever since Edward Angle introduced his edgewise appliance in 1925, orthodontic innovators have been working to improve on not only its original design, but also the method of attachment. Our "strap-ups" have evolved from banding to bonding, from labial to lingual, and from metallic to clear. But, as Angle would be pleased to learn, we still call it edgewise.

Introduction Composite materials are weak normal to the plane of the laminate due to a lack of through-thickness reinforcement, with strength dictated by the brittle epoxy matrix. Therefore it is important to evaluate the through-thickness load transfer in composite bonded joints because of their discontinuous nature to improve confidence in the join and inform more efficient joint designs. A d...

Beginning with the Pronto4TM Strap-on Autonomy System — a retrofit kit that makes any existing vehicle with a steering wheel a drive-by-wire system — and including a flexible, shared variable software base running on an open architecture system, DesignJug is enhancing its technology by creating a new sensor platform with supporting software that provides input to the team’s Actively Refined Rea...

Wireless PPG devices were developed and embedded in everyday clothes (bandage, scarf, cycling glove and wrist strap) to monitor cardiovascular state of free-moving persons. The corresponding software for measurements also has been developed and tested in laboratory. Real-time measurements of PPG signals were taken in parallel with a professional ECG reference device, and high correlation was de...
