In this issue of the American Journal of Neuroradiology, Marshall et al report the patterns of injury found in children suffering severe or fatal air bag trauma during low-velocity motor vehicle accidents (page 1599). Their results suggest that head trauma is the most important mechanism of injury in infants in rear-facing seats, and that craniofacial and cervical spine injuries are most signif...

Research and evelopment of microelectromechanical systems (MEMS) has hown a significant promise for a variety of commercial applications. For example, accelerometers are widely used for air bag in automobile, MEMS inkjet print heads re used for printers, gyroscopes for guidance and navigation and pressure sensors for various industrial applications. Some of the MEMS devices have potential to be...

A 59-year-old woman self presented to the emergency department with a painful right eye following a motor vehicle accident. She had reduced visual acuity and the eye had an alkaline pH with complete corneal uptake of fluorescein. Diagnosis of corneal abrasion and alkali burn to her right eye secondary to inflation of a driver's automobile airbag was made. The eye was irrigated with normal salin...

  Introduction: Several studies have discussed to the electron contamination caused by the air column between the head of linac and patient for photon beams. Since it is not possible to measure the electron contamination with practical dosimetry, the Monte Carlo technique is an appropriate and accurate choice to calculate particle flounce in radiation therapy. The purpose of t...

The National Highway Traffic Safety Administration (NHTSA) has been monitoring and gathering information on air bag related injuries and fatalities in its data collection programs since air bags were introduced. As frontal air bag technology has progressed from barrier certified (a.k.a. first generation) to sled certified (a.k.a redesigned) and to advanced certified air bag systems, there has b...

The UK Co-operative Crash Injury Study currently includes data on 205 seat belted drivers from frontal impacts in which an air bag deployed; of these, 142 suffered some degree of injury. To detect the influence of frontal air bags, the distribution of injury over the body regions of these drivers was compared to that of a much larger group from vehicles without air bags. The injured drivers fro...

On March 19, 1997, the National Highway Traffic Safety Administration (NHTSA) published a Final Rule amending FMVSS No. 208 to allow manufacturers to de-power air bags in their passenger vehicles. This is considered an interim solution to the problems associated with aggressive air bag deployments. Consequently, the amended rule has a sunset provision that removes the amendment, with the additi...

BACKGROUND Air stacking improves cough effectiveness in people with Duchenne muscular dystrophy (DMD) and respiratory muscle weakness. However, it is not known whether air stacking is more effective via a resuscitator bag or a home ventilator. METHODS This prospective randomized study investigated the effect of air stacking via a volume-cycled home ventilator versus via a resuscitator bag in ...

This paper characterizes the field performance of occupant restraint systems designed with advanced air bag features including those specified in the US Federal Motor Vehicle Safety Standard (FMVSS) No. 208 for advanced air bags, through the use of Event Data Recorders (EDRs). Although advanced restraint systems have been extensively tested in the laboratory, we are only beginning to understand...
