FOUR WAY ADJUSTABLE HEAD RESTRAINT SYSTEM

2019-11-21
2019-28-2528
To reduce the incidence of whiplash-associated disorders caused by rear impacts, head restraints should be closer to the head which decreases the amount of relative motion and it is believed to reduce the risk of soft tissue neck injury. Drivers are raising complaints that the head restraint causes discomfort by interfering with their preferred head position, forcing them to select a more reclined seat back angle [1]. This paper is about the importance of head restraint system and how it can be improved by adjusting the angle between the head restraint and passenger`s head. It is essential to carry out research on head restraint that can be adjusted in forward and backward direction letting the cost of seats remain in budget.

2019-28-2547
Research and/or Engineering Questing/Objectives: Safety of the occupant in passenger cars is one of the regulatory requirements in many developed countries. This includes upper interior head impact load case of the unbelted occupant during crash (FMVSS 201U) as one of them. During a crash event the occupant head can collide with the interior parts of the vehicle, such as a headliner, pillar trim and other subsequent components in the loading direction. Injury on the head is quantified in terms of the Head Injury Criterion of a crash test dummy (HIC(d)) value which should be less than 1000 per standard. Several ways can be adopted to reduce the HIC(d) value. These include a change in the design of ribs in the safety plastic components, headliner profile change, use of countermeasure foam between headliner and the exterior sheet metal parts, or a combination of any of these to absorb the energy of impact.

2019-28-2551
Head injuries are the main source of road fatalities in when a pedestrian is involved in an accident with the vehicle. The frontal part of vehicle such as engine hood, lower-windshield area and A-pillars are the possible location of head impact in such accidents. The head impact with hard points located in these areas result in the fatal head injuries. The effect of impact can be reduced by using the deployable pedestrian protection systems (DPPS) such as hood-lifters and windshield airbag in the vehicle. The study shows how these systems are effective in reducing the fatalities in pedestrian accidents and how to evaluate the performance of these deployable systems.

2019-11-21
2019-28-2436
When i decided to buy a second hand car from a dealer to learn driving, i was sceptical of the mileage usage for which a particular price was charged. Though the well know dealer told me a about the car, its previous usage, the fact that there were no accidents, and so on, there was no reliable way to verify what the dealer was offering. In order to solve such issues, we are looking at a disruptive technique which will cause a complete paradigm shift - by using blockchain technique. This paper talks about the basics of the blockchain technology and its relevance in automotive industry. We also look at some real life scenarios, where this technology helps to build reliability as one of the implicit requirements. We will start looking at how the block chain will help to reliably select the right components in the assembly line. Also we look at different aspects of software architecture like security and how blockchain can provide solutions in this area.

2019-28-2489
Research Objective The objective of the paper is to research what are the changes in experiences being brought about due to the advent of Electric Vehicles (EVs). EVs are silent, have less complex propulsion system, and have free space under the hood, amongst other things. Each change brings about both good and bad experiences across the spectrum of users. Some of the bad experiences can be safety incidents leading to death as well. Researching the areas that are harmful to end users, including pedestrians, will be our focus area. Methodology Our methodology will look at the changes at the vehicle architecture level which are inherent to the EV design. Research how are the experiences so far due to these changes. Are these just inconveniences or safety hazards? EVs have excellent NVH characteristics. A farmer may love a silent tractor, but a racing enthusiast may not like a relatively silent sports car.

Self-affinity of an Aircraft Pilot's Gaze Direction as a Marker of Visual Tunneling

2019-09-16
2019-01-1852
For the last few years, a great deal of interest has been paid to crew monitoring systems in order to address potential safety problems during a flight. They aim at detecting any degraded physiological and/or cognitive state of an aircraft pilot or crew, such as visual tunneling, also called inattentional blindness. Indeed, they might have a negative impact on the performance to pursue the mission with adequate flight safety levels. One of the usual approaches consists in using sensors to collect physiological signals which are then analyzed. Two main families exist to process the signals. The first one combines feature extraction and machine learning whereas the second is based on deep-learning approaches which require a large amount of labeled data. In this work, we focused on the first family.

WIP
J1050
This SAE Recommended Practice establishes methods for describing and measuring the driver's field of view. The document describes three methods for measuring the direct and indirect fields of view and the extent of obstructions within those fields. The first method uses any single pair of eye points to determine the fields or obstructions that would be seen by an individual driver. The second method uses the SAE Eyellipses defined in SAE J941 to determine the largest fields or obstructions that would be seen for a given percentage of the driving population. The third method uses specific eye points defined in SAE J941 to measure the extent of a specific field of view or obstruction for which those points were developed.

AIR1600B
The environmental factors of prime importance in the transport of animals in aircraft are air temperature, humidity and carbon dioxide concentration, and of course space (or volume) limitations. Secondary factors are air velocity, noise, lighting, etc. Pressure isnot addressed herein as pressure levels and rates of change are totally dictated by human occupancy requirements. Some basic governmental documents, such as References 1, 2 and 3, define overall requirements for animal transportation, but with very limited data on environmental requirements. Reference 4 gives some airplane characteristics measured during animal transportation from the USA to foreign destinations. Temperature and humidity profiles are indicative of airplane characteristics. This report presents information on the temperature, humidity, ventilation, and carbon dioxide limitations and the metabolic heat release rates for animals which will allow the determination of the environment required by th animals.
