Multisensor Strategies to Assist Blind People Using Gsm

MULTISENSOR STRATEGIES TO SUPPORT BLIND PEOPLE USING GSM Abstract: The development of electronic sensing devices for the visually impaired requires knowledge of the needs and abilities of this class of people. In this project we present a rough analysis that can be used to properly define the criteria to be adopted for the design of such devices. In particular, attention will be focused on clear-path indicators, highlighting their role in orientation and mobility tasks. A new device belonging to this class is presented. The detector is based on a multisensor strategy and adopts smart signal processing to provide the user with suitable information about the position of objects hindering his or her path. Experimental trials demonstrate the efficiency of the device developed. Introduction: About 1% of the human population is visually impaired, and amongst them about 10% is fully blind. One of the consequences of being visually impaired is the limitations in mobility. For global navigation, many tools already exist. For instance, in outdoor situations, handheld GPS systems for the blind are now available. These tools are not helpful for local navigation: local path planning and collision avoidance. The traditional tools, i. e. the guide dog and the cane, are appreciated tools, but nevertheless these tools do not adequately solve the local navigation problems. Guide dogs are not employable at a large scale (the training capacity in the Netherlands is about 100 guide dogs yearly; just enough to help about 1000 users). The cane is too restrictive. The goal of this research is to develop a wearable tool that assists the blind to accomplish his local navigation tasks. Fig shows the architecture of the proposed tool. It consists of a sensory system controlled by the user. The primary data needed for local navigation is range data (which is not necessarily obtained from visual data alone; at this point, the type of sensors is still an open question). The mapper converts the range data into map data. The local map is the input to a warning system that transforms the map data into a form that is suitable for communication. In order to give the blind person freedom of movement, he must be able to control the focus of attention of the sensory system. For hat purpose, the tool must be provided with a man-machine interface Block diagram: Ultrasonic sensor Object detect sensor circuit Alarm MAX 232 Microcontroller At89C2051 GSM module RF Tx RF Encoder RF Rx Decoder DSP Speech IC Head phone Amplifier The ultimate goal of this project is to provide an electronic tool for the local navigation task of the blind. The tool must provide information about the dire ct surroundings of the blind to enable him to move around without collisions. We assume that, although mostly unknown, the environment does have some structure such as in an urban outdoor situation (e. . a street), or in an indoor situation: smooth floors, now and then a doorstep, stairs, walls, door openings and all kind of objects that possibly obstruct the passage. We start with three sensor types: stereovision, optical flow, and sonar. Preliminary research has shown that other types of sensors are also of interest, e. g. ladar, radar and infrared (detection of people and traffic). The system should be expandable such that the information from these types of sensors can be integrated easily in a later stage of the project. Functioning overview of this Projects: 1) Whenever the blind want go to particular place, before that he will set the path through mobile. 2) Wherever he wants to go he has to carry this system. 3) When he is going out his system will communicate to house through GSM. 4) After receiving the data from blind system, it will communicate through voice using head phone. 5) This same data will send to house by GSM. 6) The house members can monitor the blind through mobile and which street, which area he is going. ) This system will support the blind and the children also. 8) The ultrasonic will support the blind distance of each object. 9) RF will support the path name, signal identification. Advantages: 1) Automation of all Customers to communicate through remote GSM using mobile. 2) Save data using automatic control systems. 3) Less cost to communicate. 4) Less power to automate. 5) Increase Safety. 6) To increase n number of person to communicate and automate. 7) Easy and fast identific ation system. Future scope: The application of this project to help navigate people around unknown places has a large scope of development in the field of technologies it uses. With the advancement in the technology, readers are getting smaller and faster with greater ability to self program. Conclusion: We made an attempt to create a prototype for assisting blind people to sense the objects around them so that we can reduce the probability of collisions. More over by using more efficient and reliable components we can make a reliable one which effectively visualizes the blind people. 1.

Mental Behavioral Case Study Essay

A lady came into the emergency room, she felt as though she had maybe had a stroke. We started to ask her questions, we asked her how long she had been feeling this way and she told us five days. She was then ask, what some of her symptoms were. She began to tell us that she was preparing for a weekend in Vegas when she noticed that her left I started to jump, she thought nothing of it. It the jumping persisted, it continued to annoy her. The woman began to say that she carried on with her plans. She then notice that her eyebrows would not move on that side and that her taste was different. Her tongue began to feel numb as well. She began to cry because she really felt as though she had a stroke and why did she not have any symptoms or any illnesses that could provoke it to happen. She said that what really made her come in was that her mouth began to twist and her eye drooped. Then the doctor asked her questions about her last time she gave birth or maybe a sinus infection or something that dealt with her stressing. She then told the doctor that she had a baby about 5 months ago. Then the doctor told her since it has been about five days you are a lucky young lady. I don’t believe this is a stroke, â€Å"I think that this is Bell’s palsy. I then told her not to worry it was still in the primary stages and that I would need to put her on a steroid and a antibiotic to help her get better. I then began to tell her that she was lucky she came when she did because some people stay with Bell’s palsy without ever getting it corrected. She then asked me what Bell’s palsy is. I explained to her that Bell’s palsy is a form of temporary facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal called the fallopian canal in the skull , beneath the ear, to the muscles on each side of the  face. I then explained to her that the disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell’s palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides. I then went on to tell the patient that Bell’s palsy afflicts approximately 40,000 Americans each year. It affects men and women equally and can occur at any age, but it is less common before age 15 or after age 60. It disproportionately attacks people who have diabetes or upper respiratory ailments such as the flu or a cold. I told her that it can occur after pregnancy as well. I then said to her that some people that are affected by the disease their family has to be supportive because some people have after effects or may not have caught it in time like she did to have the chance to have their feeling come back into their face. This affects them in society because people are cruel and it can also affect being able to work or define what you can and can’t do in your life. It also will affect the ability to eat, due to the numbness of your tongue. I then told her that she had nothing to worry about she was going to be okay and she did the right thing by coming into the ER when she did just take her medications and she would soon see her smile again. We then gave her some information and websites that she could look at dealing with the disease. This would be able to help her and give her support to deal with what she was going through. I then let her know that I too have had bells’ palsy and if I could get my smile back so can she. She left the office feeling a little better knowing that her stage of disease was primary and that it was treatable.

Media and Body Image †Essay Essay

How does the media influence our body image? In what forms, does the media influence our perceptions about our body? These were the two questions that I asked myself in order to do the research paper and the panel discussion. In my opinion, I would agree that the media does influence and promote women and men to believe that the culture’s standards for body image are ideal. Hence, the phrases, â€Å"thin is in† and â€Å"the perfect body† are two examples of â€Å"eye-catching† headlines that I observed in many women magazines. I learned that the media influences us through television, fashion and health magazines, music videos, film, commercials, and various other advertisements. Sadly, as a result, this repeated exposure, the â€Å"thin† ideal, can lead many young girls in triggering eating disorders, depression, low self-esteem, stress, and suicide. After acquiring this relevant information, I decided to focus my research on what type of media in fluences elementary school children and the adolescent teenager. The three central types of media that I found that did indeed influence body image are: Fashion magazines, famous top-models and actresses, and teenage or young adult women in the music industry. According to the Seretean Center for Health Promotion, † the term, â€Å"body image† has been coined to describe a person’s inner sense of satisfaction or dissatisfaction with the physical appearance of her/his body.† (From The Wellness Column, April 1, 1996.) In my research, I found that many young girls are dissatisfied with their bodies and many â€Å"strive† to look like the â€Å"waif-thin† models or actresses one sees on television or in fashion magazines. There was a lot of information and facts on body and image that I found on the Internet. However, one website, Just Think Foundation, supported my belief that the media, magazines in particular, do indeed influence young girls to be â€Å"thin† in order to be popular and beautiful in our society. For example, I was in alarmed to learn that â€Å"eighty percent of 10-year-old American girls diet; more than five million Americans suffer from eating disorders and ninety percent of those are adolescent and young adult women; the number one magic wish for young girls age 11-17 is to be thinner; and between elementary and high school, the percentage of girls in the U.S. who are â€Å"happy with the way I am† drops from 60% to 29%.† (from Just Think Foundation) These facts were  from the JTF’s Body Image Project compiled by Jean Holzgang that is an awareness campaign on body image. In fashion magazines, many young girls see â€Å"waif-thin† models like Kate Moss who is one of many top models that sadly represents the â€Å"perfect† body image that young girls are striving towards. Unfortunately, many teen girls do not understand that looking exactly like their favorite supermodel is unrealistic. In fact, as for the supermodel photos, many are retouched before they are printed out, the â€Å"fashion clothes† are often duct-taped to enhance fit, many blemishes are covered or altered, there is at least two inches removed from the thighs, and the average fashion model weighs 23-25% less than the average woman. All this in order to create that â€Å"ideal† or â€Å"perfect† body image everyone is striving for and sadly dying for. This compulsion to be â€Å"thin† has led many young girls to have a negative body image that dangerously paves the way to eating disorders, such as Anorexia and Bulimia, in order for them to achieve their desire for thinness. In television and movies, many teen girls watch and observe these actresses, such as Calista Flockhart, Courtney Cox, Jennifer Aniston, Gweneth Paltrow, Lara Flynn Boyle, and many others who have seemed to have went from an â€Å"average† weight to a â€Å"sickly, death look†. This seems to be setting a dangerous trend for the American culture, particularly women and young girls. In fact, there are endless images of thin women on television, in movies, in women and men’s magazines and in commercials. For instance, these â€Å"Hollywood role models† do have a great impact on young viewers and many parents are very worried that their daughters are trying to imitate their favorite stars. According to Adrienne Ressler, body-image specialist at the Renfrew Center in Coconut Creek, Fla., â€Å"For adolescents, the ideal for the person they want to be when they grow up is either a movie star, TV actress or supermodel, and the emphasis is very much on external appearance. Our patients would die-and practically do-to look like Calista Flockhart.† ( People, 10-18-99) In the music industry, the most popular media influence is the music video and the types of fashion trends the performer displays onstage. The most popular young adult performer is teen sensation Britney Spears. This pretty, young lady is only 17 years old and already has had a huge impact on the teen girls. For example, recently, Miss Spears was on the cover of Rolling Stone magazine and she stirred up controversy when it appeared to look like the singer had  breast enhancements or simply, breast implants. (In all fairness, I did not have a chance to view that cover of Rolling Stone.) Miss Spears has denied the breast implant allegation and is quoted as saying; â€Å"her mother would kill her if she had such a operation.† However, I read that many fans believe that she does look different from her first video, Baby One More Time, with her latest, Sometimes, in that her breasts do look like they were surgically enhanced. This rumor has a great deal of parents worried that their own daughters might want to emulate the teen pop idol because she is promoting the â€Å"ideal image† of a young girls body. Another example of a â€Å"music video† image is Victoria Beckham (Posh Spice) of the well-known Spice Girls. She was considered a â€Å"head-turner† because of her curvaceous good looks and designer clothes. So, know one would have thought of her as over-weight or too curvy, but at a recent Fashion party, many onlookers were stunned to see â€Å"Beckham’s jutting ribs and collarbones† that fellow guests replied, â€Å"She definitely looks like she’s had a dramatic weight loss.† (People, 10-18-99) These two examples plus the dozens of others I have read thro ugh my research, have allowed me to come to the conclusion that, many of Hollywood’s most notable actresses and performers have become partners in the â€Å"thin is in† look in this industry. In my opinion, this is very disturbing and very dangerous for many young girls who look up to these women as â€Å"Role models.† In conclusion, I hope that T.V., magazines, music videos, commercials, retail stores and other mediums realize that there are women of all different shapes and sizes, there is a higher percentage of women that are usually an average size of 12 and there is evidence that a lesser percentage of women who are a size 2 to 4. Unfortunately, it is the size 2 to 4 women who are being recognized as the â€Å"ideal† body image in our society. Furthermore, I would rather have more women like Kate Winslet, Rosie O’Donnell, Emme, and many other â€Å"average† women on the covers of popular magazines and in television. These are the â€Å"true role models† for me, the ones who promote healthy ways to lose weight, promote healthy ways to like yourself for who you are, and not promote the unhealthy â€Å"body image† that engrosses our mind

History of Red Cross Research Paper Example | Topics and Well Written Essays - 2500 words

History of Red Cross - Research Paper Example He took the help of the villagers at Castiglione to comfort and give medical care to the injured. He worked for the injured for three days without sleep. When he returned to Geneva he was troubled by atrocious visions of the war, he experienced in Solferino. He worked really hard to make sure that the terrible suffering he has gone through must not take place again. It was in 1862 that Dunant published a book by the name of â€Å"A Memory of Solferino†. His book fostered the idea that in every country there must be an institute that must work for providing relief to the people wounded in war. This society must also help the army to carry out their task of helping the wounded militants. The Formation of Red Cross Gustave Moynier who was an advocate in Geneva showed immediate interest to the idea fostered by Dunant in his book. Moynier within no time formed an International Committee of Relief for the ones injured in war, which was later named as â€Å"International Committee o f Red Cross†. Delegates from sixteen states around the world, met at Geneva for the approval of the Geneva committee on 26 to 29 October. The delegates decided that every state will form within their country a private institute whose task will be to provide relief (medical services) to the military and the ones wounded in war. The medical equipment of the relief worker will be labeled with a unique emblem, a red cross with white background. Swiss government in 1864 organized a diplomatic conference at Geneva which brought together representatives from twelve different states. It was on 22 August 1864, that the first Geneva Convention was signed, whereas the others followed soon after this event took place. At that time battles or wars were considered to be irreconcilable. The First Geneva Conference stressed upon the enforcement of certain humanitarian rules during the war as well(About the International Committee of the Red Cross, 2013). Development of Red Cross The founders of Red Cross assigned to themselves the task to foster the creation national societies within different states. By 1874 there were about twenty-two national societies in different states of Europe. However Red Cross was gradually spreading to other continents as well. During the Turkish-Russian war in 1876, the Red Cross informed the government of Switzerland that they would be taking up the â€Å"red crescent† emblem to be placed on their ambulances instead of the â€Å"red cross† From 1864 to 1914 war and disturbance broke out in many parts of the world, at that time â€Å"Red Crescent† and â€Å"Red Cross† were busy giving their services to the men suffering. Above all, it was during the First World War when Red Cross Societies from all the countries were asked to give their services. At that time, all the Red Cross societies working in different countries organized hospital and ambulances for the wounded (History of Organization, 1963). The activities of the Red Cross expanded rapidly, following the foundation of the Central Trading Agenc

Predict future business opportunities and threats in the national and Essay

Predict future business opportunities and threats in the national and global environment - Essay Example The purpose of this paper is to describe and analyze threats and opportunities that businesses face in the future domestically and internationally. The economies of countries have become more interconnected than in the past. A potential opportunity for businesses in the global economy is to take advantage of the growing trade from emerging economies. Emerging economies can be defined as rapidly growing and volatile economies that promise huge potential for growth, but also pose significant political, monetary, and social risks (Businessdictionary). In a lot of these emerging economies there are a growing number of middle class citizens that are looking to purchase consumer products in order to increase their standard of living. Two examples emerging economies that pose a tremendous opportunity for companies looking to expand into foreign markets due to their large populations are China and India. The combined population of China and India account for over one-third of the global popu lation. A market that has been forgotten by the business community which poses an opportunity for companies looking to expand oversees is Africa. The Sub-Sahara African region is considered by many economists as the frontier market. Africa has six of the ten fastest economies in the world (Harare and Johannesburg). Another reason that Africa represents a huge opportunity for businesses in the future is due to the fact that within three decades Africa will surpasses China as the world’s largest workforce. In the future another factor that represents an opportunity for businesses is technological advancement. Companies must invest money in research and development in order to accelerate the process of innovation to bring new technologies to the market. Companies will be able to improve their manufacturing capabilities as technologies such as robotics become advance enough to replace the need for human labor. Automation provides several advantages to companies such as lower labo r costs and greater productivity. â€Å"Automation created hundreds of millions of jobs in entirely new fields† (Kelly). The premise that robotics and automation will increase unemployment is erroneous. The need of low skilled laborers will decrease in the future, but the demand for skilled laborers will rise. New technologies are going to create new markets and more opportunities for new businesses. The supply of labor in the future will change in regards to how companies recruit personnel. The old approach of focusing mainly in employees located near the geographical location of the business will change. Companies in the future are going to look more to recruit employees internationally because it will become harder to find educated employees in many fields from the local labor supply. The governments of the different nations across the world are going to have to change their immigration policies in order to adjust to the needs of global corporations. In the future companie s will be able to reduce their operating costs associated with energy due to the fact that renewable energy sources will become cheap enough to replace the dependency on petroleum as the main source of energy and gasoline. Despite all the positive scenarios of the future of business there are also threats that corporations must deal with. Robotics poses both an opportunity and a threat. If machines evolve enough to have artificial intelligence that is smarter than the human brain it is possible that the robotics

Compare and contrast Marx idea of Class and Durkheims Division of Essay

Compare and contrast Marx idea of Class and Durkheims Division of Labour - Essay Example Those who accepted it became modern societies or Capitalist societies. Many theorists in the sociology have tried to explain or simplify the complexities of these societies, among the greatest of them Karl Marx and Emile Durkheim. Karl Marx and Emile Durkheim are considered as the fathers of sociology. Both of them had a deep power on the development of sociological theories. Karl Marx (1818-1883) wrote the Economic and Philosophic Manuscripts in 1844, and one of these documents, titled Estranged Labor, includes his debate of alienation - the experience of isolation resulting from powerlessness. Marx’s main concern was with the formations of capitalism that result this alienation. He gave a theory of alienation deep-rooted in social composition. In his theory he wanted to get across two vital and foremost ideas. Firstly, that mankind make society, and at some point society is a natural extension of their nature and their being, and secondly, as modern society develops, human beings begin to feels that society is not of their making, and no longer reflects their being or their nature, but instead appears to be alien. Marx argued that laboring was the primary way by which human kind exposed themselves in nature and history. According to Marx, alienation breaks fundamental association individuals have to the self-defining aspect of laboring activity. He identified four characteristics of alienation: Product alienation takes place when workers become alienated from the objects they produce. The product of their labor belongs to the capitalists not to the workers. The capitalists may utilize it however they wish mostly to sell the product to get profit. Furthermore, workers often do not have information of the features of production they are not involved in, and have no sense of their job in the entire production process. Alienation from productive activity refers that workers do not work their own satisfaction to fulfil their needs but capitalism makes

Research Progress Report Assignment Example | Topics and Well Written Essays - 1500 words

Research Progress Report - Assignment Example There are several vehicles that authorities can employ to realize the genuine, effective participation of citizens in the governance process. One such vehicle is community councils. Following the amalgamation of Toronto in 1998, six community councils were established. The community councils were meant to serve as the platform for â€Å"participating† the residents of Metropolitan Toronto, the new amalgamated city. The notion of "amalgamation" entails merging smaller local authorities with one larger municipality to form one large metropolitan area. Promoters of city amalgamations argue that it is more cost-effective to provide services and goods to one larger municipality than in several small local government areas(Schwartz, 2010). However, many scholars are of the view that amalgamation has not worked for Toronto and that the community councils are weak. This paper compares the Toronto model with two others: New York and Montreal. Scholars consider New York a success and Montreal, like Toronto, a failure. Based on the findings of the case studies, the author recommends two reform options for Toronto. Until 1997, Toronto had a two-tier regional government. The Municipality of Metropolitan Toronto comprised the upper tier while the lower tier comprised the municipalities of North York, East York, Scarborough and Toronto and the borough of York. In late 1996, the premier of Ontario proposed the amalgamation of Metropolitan Toronto. They argued that the move could save $645 million during the transition and $300 million a year afterthat (Schwartz, 2010). However, a report by KPMG revealed that the transition cost the government of Ontario $275 million while they managed to save only $135 million a year. As of 2008, the city’s budget stood at $8.1 billion, up from $5 billion in 1997. Only the number of politicians fell, but increases in the councilors staff and office budgets have canceled any cost
