INTRODUCTION
In 2004, there were about 17,000 alcohol related traffic fatalities in the U.S., which represented about 40% of about 42,500 all traffic fatalities. This represents one alcohol related fatality every 31 minutes. There were also 248,000 people were injured in traffic accidents where alcohol was involved – about one every 2 minutes! Perhaps more disturbingly, in 85% of all alcohol-related fatalities, the blood-alcohol concentration (BAC) of those involved in the accident was reported to be above 0.08%, the legal limit in the U.S.
The Invention relates to apparatus for preventing a motorcar from being driven by a drunk driver. Traffic accidents caused by drunk drivers not only represent a significant portion of all automobile accidents, but they frequently involve fatalities. However, an effective apparatus for preventing such kinds of accidents has not yet been developed.
HISTORY
An object of this invention is to provide a novel and prevention drunken driving of a Motorcar by cutting-off the Fuel supply and induce the alarm & Indicators, but also it enabling a person who is not drunk to drive the same Motorcar. About 51% had a BAC over 0.16, a level at which an individual is typically severely intoxicated As high and disturbing these numbers are, there is a bit of good. News in this: this numbers represent about 33% drop in alcohol related fatalities (from 26000) in 1982 While the reasons for this drop is many, one could include toughened. Traffic laws and the now ubiquitous use of breath analyzers that can be used on the spot to test near-objectively test the individual’s level of intoxication. Breath analyzers (note that a Breathalyzer is a particular brand name) are now available even for consumers who can purchase these and test their BAC at any time. These devices, like countless other consumer or medical grade biomedical equipments are designed by biomedical engineers who typically have an electrical and computer engineering background. The goal of this laboratory exercise is to give you a glimpse of this exciting and rapidly growing area of biomedical engineering, where engineering solutions are sought for real-world problems in medicine. In this lab, you will build a prototype of such a breath analyzer. On the other hand, no concept of biological origin – including designing devices for biomedical applications – can be fully appreciated if such an exercise is divorced from the underlying physiological underpinnings. It is therefore important to at least have some understanding of the physiological affects of alcohol on humans, more specifically, on the central nervous system. This physiological effect and the associated impairment that causes ten thousands of alcohol related traffic fatalities. You are therefore asked to read about the central nervous system and the effect of alcohol on this system before coming to lab.
BLOOD ALCOHOL CONTENT
An estimate of BAC can be made from the charts shown below as Figure 1 and Figure 2. As a notional sensor, the Breath Alcohol Indicator as we are building it today can provide a quick check about whether you are in the red zone, or near the red zone, in the event that you need to drive. As a safety accessory, this may be the convincing data that a taxicab or other alternative to driving is appropriate. Detailed examination of [4], published as a web page by a campus police organization, and says repeatedly in the most direct possible terms that driving with any alcohol in your system is ill advised. About 51% had a BAC over 0.16, a level at which an individual is typically severely intoxicated As high and disturbing these numbers are, there is a bit of good. News in this: this numbers represent about 33% drop in alcohol related fatalities (from 26000) in 1982 While the reasons for this drop is many, one could include toughened.
