Objective – Public concern has arisen about the reliability of front airbags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed airbags in fatal frontal crashes. However, the accuracy of airbag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. Methods – Fatally...

In this paper, we propose an occupant sensing system using the sensor fusion composing of PIR (pyroelectric infrared) sensor, USD (ultrasonic distance) sensor and IRD (infrared distance) sensor for the smart airbag. These sensors are used to detect the position and body classification of occupants. By mounting these sensors within vehicles jig, the proposed system is experimentally evaluated in...

This paper describes curtain airbag gas delivery system development work using CFD analysis. The objective of developing gas delivery system was to achieve uniform inflation and reasonable time to position for oblique pole test with 5 %ile female. CFD analysis has been conducted to design gas delivery system of 3 row curtain airbag. The gas delivery system consists of T-diffuser and flexible ga...

The distance between the driver and the steeringwheel airbag module at the time of deployment has been identified as an important factor affecting the frequency and severity of airbag-induced injuries. Pre-crash positioning may influence the clearance at the time of deployment. Data from in-vehicle studies of driving posture were analyzed to determine the clearance between the steering wheel an...

Recently, some investigators have expressed concern about the impaired integrity and decreased tensile strength of the cornea following radial keratotomy (RK) and wound healing, because of pathological findings in human and animal corneas. Corneal tensile strength in eyes following RK has been evaluated in animal models. It has been reported that rabbit corneas require 54% less energy for ruptu...

OBJECTIVE To determine the level of child safety seat (CSS) and airbag safety knowledge in parents who utilize emergency care services for their children and to determine factors that influence knowledge of safe transportation of children. METHODS A prospective survey study was conducted in a 42 000-visit-per-year Level I trauma center and emergency department (ED) in Southern California from...

In order to satisfy the increasing safety requirements for airbag deployment systems in cars, the number of airbag actuators and sensors increases steadily. It is important to keep the complexity of the system manageable, for example by replacing the current point-to-point systems by a networked system. This paper gives an overview of such a system and discusses some of the interesting implemen...

The widespread and mandatory use of airbags has resulted in various patterns of injuries and complications unique to their use. Airbags have been implicated in a spectrum of pulmonary conditions ranging from exacerbation of asthma, reactive airway diseases to new onset asthma. We report a case of inhalational chemical pneumonitis that developed after exposure to the airbag fumes.

Unmanned Areial Vehicles(UAV)can be automatically landed on airbag using Vision based algorithm. This paper proposes a review on the novel algorithm based on the color and shape detection of airbag. Colorand shape-based detection vision algorithms are applied for robust detection under varying lighting conditions.It discuss about the various landing techniques used for aircrafts and Unmanned Ae...
