Side-curtain airbags have demonstrated the ability to help reduce the possibility of ejection and serious injury during automotive collisions. Engineers developing these new types of airbags are aided by Virtual Product Development tools (VPD), which allow the engineer to more fully analyze the airbag mechanism and dynamic inflation. Autoliv, the world’s largest manufacturer of automotive safet...

Minimizing the injury potential of the interactions between deploying airbags and car occupants is the major issue with the design of airbag systems. This concern was identified in 1964 by Carl Clark when he presented the results of human volunteer and dummy testing of the "Airstop" system that was being developed for aircraft. The following is a chronological summary of the actions taken by th...

servatively. Follow-up at 4 months showed spontaneous resolution of the subretinal fluid on optical coherence tomography (Figure 1C); visual acuity had returned to 6/60 OS but the macular hole remained open. Four months later, the patient’s vision remained stable but the subretinal fluid had returned. An inverse pseudohypopyon was visible at the macula (Figure 2), and optical coherence tomograp...

Analysis of the vehicle occupant posture is a key problem in designing “smart airbag” systems. Vision based technology could enable the use of precise information about the occupant’s size, position, and posture in making airbag deployment decisions. In this paper, we present our experiments in estimation of the body posture of a sitting person using a motion capture system that performs analys...

Presently, main applications can be found in the automotive market segment (e.g. front and side airbag sensors, ESP respectively chassis stabilization, active suspension, roll over detection). However, low-g sensors enter also new application areas like inclinometry and vibration sensing for instance for anti-theft devices or activity monitoring for pacemaker control. Like in the microelectroni...

Acoustic metamaterials possessing subwavelength characteristics can be used for low-frequency noise and vibration control. with adjustable dynamic properties further enhance their possible applications. This paper designs a kind of tunable acoustic consisting the frame structure, airbag, balancing weight. And manipulated by tuning gauge pressure gas temperature in airbag. The calculation result...

PURPOSE To report a case of airbag induced corneal ectasia. METHODS Case report. RESULTS A patient 3 years post-LASIK developed bilateral corneal ectasia worse in the right eye following airbag deployment in a road traffic accident. At last follow up, best corrected vision was 20/40 with -4.00/-4.00 x 25 in the right eye and 20/25 with -1.25/-0.50 x 135 in the left eye. CONCLUSIONS This i...
