Designing An Airbag System For A Car

RTOS must provide a priority mechanism that allows high-priority interrupts to take precedence over less important ones. Chimera implements Maximum Urgency First (MUF) scheduling algorithm which is a combination of fixed and dynamic priority scheduling. The fixed priorities are criticality and user priority. Criticality set to high or low determines if the task is critical to finish within the deadline. The dynamic priority, minimum laxity priority is an inverse of laxity defined as

The following steps need to be taken to improve the performance of a system using the theory of constraints approach;

It demonstrates the workflow behaviour of a system which describes the state of activities by showing the sequence of activities performed in different order. The diagram has branches and forks to describe conditions and parallel activities.

A system is an organized structure that has inputs and outputs that carry out a specific activity. A system is a group of components that makes up a complex functioning unit. When an element changes, the system will stop functioning right. Once the system has been defined by jurisdiction, budget, coverage requirements and user needs, the next step is to design the system using components and systems that are obtainable and have the desired features that the customer and the design engineer have agreed upon. If the design engineer is not careful, then there will be coverage, operational, maintenance and reliability issues that will plague the system forever. The equipment-engineering phase will specify each and every component in the system, (Wiesenfeld, 2010). Due to a problem or situation, there is a beginning and an end to a system that is tasked to solve that problem.

According to the National Highway Traffic Safety Administration (NHTSA), “in 2015, seat belt use in passenger vehicles saved an estimated 13,941 lives” (1). The NHTSA goes on to say that almost 30 million Americans still don’t use seat belts on a daily basis. Since vehicle accidents are among the leading causes of death in the United States and even the world, the argument to improve seat belt technology has increased dramatically. Researchers are often more concerned with whether or not people are wearing their seat belts, not the effectiveness of them, until now, although both are incredibly important. Seat belt safety, which is directly related to seat belt technology, has been shown to be increasingly ineffective because of the high severity

Front air bags have been on all new cars since 1998 and light trucks since 1999. Most vehicles had them before. Crash sensors connect to a computer and can detect a front collision and trigger the bags. The bags inflate in a few milliseconds then it starts deflating.

Today I saw a community come together in a way I have never seen before. My sister and I while driving to the nearby library as we found ourselves at the site of a car crash. We turned the corner onto the street right as another car hit a tree and totaled their car. We parked our car and we asked them if they needed help. One by one people started to get out of the car their faces full of pain and shock. All the airbags in the car had gone off and the front side of the car was completely smashed up. As they got out of the car I watched as neighbors and nearby walkers ran to the scene to help these people. A woman sat down on the grass with someone who was hurt and just talk to her and comforted her as someone else called 911, a doctor ran out

Some people believe that airbags make seat belts unnecessary. They argue that seat belts are pointless because an airbag will cushion one's impact with the steering wheel or dashboard. Although convenient to believe, this isn't true. Air bags are designed to supplement seat belts and are not a substitute for them. Seat belts are restraint devices that keep the person in position during a crash while airbags are a cushion for the face. Specifically, they are meant to cushion the face of a seat belted person. More details on this distinction are discussed next.

The article “Automakers Knew of Takata Airbag Hazard for Years, Suit Says” covered in “The New York Times” newspaper writes about that at least four automakers Ford, Honda, Nissan and Ford knew about Takata defective airbags but continued to purchase them due to low costs. The allegations came hours before the plea deal was reached between Takata, a Tokyo-based company manufacturing car airbags and its victims totaling in $125 million. These defective rupture-prone airbags resulted in exploding metal shards injuring car drivers. The company knew of the airbags defects, but continued to manufacture and sell them to the automakers. They purposely manipulated safety data to hide these defects. In the past few years, 11 deaths and over 100 injuries

Air suspension has a higher price but is worth it. Luxury cars sometimes come with air suspension or are available as an upgrade. Bags have gotten more advanced the past years because before you could not track a car with bags it had to have coilovers. Nowadays they are possible to track as well as make it possible to be comfortable for riding on the weekends. Bags will adjust to road situations, for example if you want to go to Coachella through all the bumpy roads, with a controller it is possible to control the ride height and just inflate the suspension and go over every bump without a problem. Not saying I would do this but if I had air suspension I could park anywhere I wanted without getting towed. Once the car is parked it will lower

The theoretical background for the project will be stated. The design process for the buggy system as well as a detailed manufacturing procedure of the prototype will then be described. An interpretation of the results from the design process will then be presented. The figures, tables & graphs used will be compared against one another as well as compared against theoretical results. Any issues stated during the design process will be addressed. The report will then summarize the overall findings and then provide an appendix as well as all figures, tables &

Petri net is graphical and mathematical modeling language used to describe a system. Petri nets are a strong language has been used for specification, analysis, and synthesis of programs. And it is can be used to represent the parallel or concurrent activities in a system. In this paper reviews several issues related to the Petri net modeling. The discussion is includes: Petri net models, benefits, limitations, advantages, and when it needs to use.

After the proposed system is analyzed and designed, the actual implementation of the system occurs. After implementation, working system is available and it requires timely maintenance.

Formal mathematical methods are system designs that utilize specific rigorous mathematical models in the production of software and hardware systems. The methods are unique in comparison with other methods for they utilize mathematical proof as a complement to system testing so as to ensure a perfect behavior. A formal approach to system designs ensures safety due to the complicated nature of systems.
