Bluetooth Applications

BLUETOOTH APPLICATION ABSTRACT In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper.In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives. CONTENTS: 1. INTRODUCTION 2. ROAD ACCIDENT STATISTICS 3. OPERATION 4. AUTOMATIC BRAKING SYSTEM 5. REPRESENTATION OF OUR IDEA 6. CONCLUSION 7. REFERENCES INTRODUCTION Since Bluetooth devices are capable of communicating with eight other devices simultaneously we can monitor and check the speeds of up to eight cars simultaneously, thus preventing accidents.Thus if we have two Bluetooth enabled devices in two cars the devices automatically communicate with each other when they come in the range of up to 100 meters of each other. The range is dependant on the power class of the product. Power transmission rates vary in many Bluetooth devices depending upon the power saving features available in a particular unit, bandwidth requirements, transmission distance. The statistics of road accidents is tremendous and highlights the need for such a system. The following is a statistic on the number of road accidents occurring each year.ROAD ACCIDENT STATISTICS OF INDIA 1970-2003 | |   |   |   |   |   |   | |Sl. No. | |Source:   Data received from States/UTs. | s OPERATION Because of traveling at high speeds there is a possibility of having accident. The figure 2 shows that when two cars or more come within the distance of 10 km at high speeds there is a possibility of having accidents. The Bluetooth radio is a short dist ance, low power radio operating in the unlicensed spectrum of 2. GHz and using a nominal antenna power of 20 dBm. [pic] At the 20 dB the range is 100 meters, meaning equipment must be Within 100 meters to each other (about 328 feet) to communicate using the Bluetooth standard. With the help of this technology we can send data to the eight devices. The group of eight devices is known as piconet. Here we have a piconet and a scatternet, in the piconet M is the master and S1 to S7 are the slaves [pic] Radio communication is subjected to noise and interference, as the 2. 4 GHz frequencies are shared between the all device in piconet.So the Bluetooth specification has solved this problem by employing what is called as spectrum spreading, in which the Bluetooth radio hops among different frequencies very quickly. There are 79 hops starting at 2. 402 GHz and stopping at 2. 480 GHz, each of which is displaced by 1 MHz. The Bluetooth avoids interference by hoping around these 79 frequencies 1600 times per second. So in order to avoid it we use bluetooth equipped car, in which each car have bluetooth transmitter and receiver. And the every car should have mini computer to monitor the relative position of the car with the other car. pic]When any car comes close together bluetooth device sends warning signal to the car. Based on the type of warning signal received the computer sends signal to the brake control system to slow down the speed of the car. There are two types of control signals. First type of signal control the speed of the car and the second type of signal is to overtake the car which is moving forward. Schematic diagram of car: [pic] AUTOMTIC BRAKE SYSTEM: The automatic brake system is the next generation braking system for controlling the speed of the car.On receiving the control signal from the traveling car the computer inside the car manipulates the signal and gives control signal to the braking system. There are four main components to an automatic brak ing system: †¢ speed sensors †¢ pump †¢ valves †¢ controller [pic] Automatic braking pump and valves The computer constantly monitors the distance between each of these cars and when it senses that the car is getting too close it moves the hydraulic valves to increase the pressure on the braking circuit, effectively increasing the braking force on the wheels.If the distance between two vehicle is within the 100m the Bluetooth devices get enabled and if the distance come closer within 10m the automatic braking system takes the control. After the speed of the car is reduced and distance increased the hydraulic valves decreases the pressure on the braking circuit, thus effectively decrease the braking force on the wheels. The following steps show the various functions of the hydraulic valves: †¢ in position one, the valve is open; pressure from the master cylinder is passed right through to the brake. in position two, the valve blocks the line, isolating that b rake from the master cylinder. This prevents the pressure from rising further should the driver push the brake pedal harder. †¢ in position three, the valve releases some of the pressure from the brake.REPRESENTATION OF OUR IDEA In the figure 7 when car A and car B come within the range of 100m both the Bluetooth devices get enabled and if any one of the car comes too fast then the bluetooth device sends a warning signal to the other car and it processes the signal and gives it to the automatic braking system. pic] CONCLUSION: The Bluetooth technology is being widely adopted by the Industry leaders. The possibility for new applications is very exciting with this Versatile technology. It provides a simple, logical answer to all the Problems-which is built a single common radio into every mobile computer, then neither do companies have to worry about WAN, nor do communication companies need to worry about building external cables. The Bluetooth communication device will thus be a small, low powered radio in a chip that will talk to other Bluetooth enabled products.Bluetooth has been designed to solve a number of connectivity problems experienced by the mobile workers & consumers. Thus, this technology helps make the electronic devices more user friendly and helps address various other problems like accidents. ———————– Fig 1 CAR 1 CAR 6 CAR 4 CAR 3 CAR 7 CAR 8 CAR 5 CAR 2 MINI COMPUTER INSIDE THE CAR Fig 2 M S72222222 S1 M2 S2 S1 M1/S S1 S1/S3 M1 S3 Fig 3 Fig 4 Fig 5 Fig 6 Within 10m Sends warning signal Receives signal and control the speed of car Fig 7

The policies directed at the capital account could include interest rate policy, action policy (related to Foreign Direct Investments) and complementary infrastructure and Other supply side policies such as employer CAP levels. To manipulate current account, the government by and large does not use protectionism except for domestic service sectors, such as banking, fiscal policy due to small multiplier and does not aggressively undervalue currency because of fears of imported inflation.For the capital account, since we have elected to choose exchange rates and free capital movements as our two choices, it does not use interest rate and UAPITA controls. Singapore does not want to scare away Foreign Direct Investments by implementing controls. Singapore mainly relies on supply side policies as the government tends to be more far-sighted and focuses on returns on the long run. The Balance of Payments will be analyzed as such.Even in crisis periods such as early 2009, Singapore does not react much with exchange rate changes but instead encouraging foreign and few domestic firms to remain in Singapore by offering lower wage (and subsidizing for the lowest wage) and better tax areas. The opinion is that sudden exchange rate changes are inflationary and destabilize. Therefore, the typical exchange rate policy has been one of the slow and steady appreciate of the Singapore dollar in line with gradual improvement in performance of the current account.The underlying policy behind the improved current account performance and how the exchange rate strengthened Balance of Payments come from the following. If rusty, Singapore develops current account in areas of higher value added to AP into growing world of incomes and to avoid goods where prices are volatile, such as those primary products exported by many developing countries. Also, Singapore constantly aims to raise value added to stay ahead of other countries which are building their current account.This involves increa sing expenditure on human capital and strategic alliances with firms that can make use of such labor by offering supply side support. Critic: Employer's CAP, Wage Flexibility, PR Protection, Physical infrastructure improvement, corporate tax regimes, manpower development There is not much to change because Singapore has one of the strongest current accounts in the world.

In The Workplace In many business's today important vital customer information is stored within a company's database, easily accessed by employees with the right verification. The vulnerability of sensitive information is at an alarming risk. Most company's password policies are vague only asking for a one step verification, which entails either the employee's date of birth, or the last four digits of their social security number. I have vast experience working in hotels, and the one common thing I have personally foundIs that the password authentication process can easily be manipulated. As years of working In the hotel business I have had access to customers' credit card numbers, addresses, phone numbers, as well as email addresses. I have personally seen the ease of accessing another person's password. Hypothetically In the hotel business If a customer or any other unauthorized person or persons were able to access the hotel computers, It wouldn't be too difficult to hack one of t he employees' passwords and gain access to the customer files containing all of their information.It is my personal pinion that every company big or small should have a complex password authentication system in place to protect the very customers that keep them afloat. We see it not quite daily but do see it often in the news where business's get hacked into and hundreds of thousands of people are affected. Most of the time these â€Å"hacks† would have been easily avoided had the company put in place a more complex password authentication system. In closing I hope to one day develop a hack proof password system, to protect not only consumers, but corporate database, as well as their integrity.

Mathematical Formula in Material Cost Accounting and Control Essay

Mathematical Formula in Material Cost Accounting and Control - Essay Example Also, overstocking requires more storage space which, in turn, means an increase in insurance expenses, storage costs and deterioration in quality and depreciation in quantity. On the other hand, if materials are understocked, frequent orders have to be placed in small quantities and there is a chance of "stock outs" also. Hence, the tack of the manager is to find the most economic order which s very essential for cost management and control. The cost of carrying the inventory and the ordering cost is inversely proportional to each other. The costs of placing the order decreases as the size of the order increases, because with the bigger size of the order, the number of the orders will be lower. However, simultaneously the costs of carrying the inventory will go up because the purchases have been made in large quantities. It may be possible to have appointed which provides the lowest total cost and the point, which is the ideal size of the order is known as the Economic Order Quantity(EOQ). The EOQ is one where the cost of carrying inventory is equal or almost equal to the cost of not carrying inventory (cost of placing the order), i.e., at EOQ level, the total of inventory carrying cost and the ordering cost is minimum which can be determined mathematically s follows: The EOQ is 600 units, i.e., 10 orders per year are needed.

AIDS in the United States Research Paper Example | Topics and Well Written Essays - 750 words

AIDS in the United States - Research Paper Example 20 percent of adults have AIDS in seven countries of this area of Africa. The initial slow reaction and lack of concern during the early 1980’s and beyond by the U.S. is clear today. Forty thousand new instances of the disease is reported each year but exactly how many persons are infected is not known because the method intended used to track AIDS is flawed and not likely to be fixed anytime soon. However, the social effect of AIDS has been widely acknowledged. This has served to inform the public and slow the progression of the epidemic but not in the African American community. The continuing proliferation of AIDS is allowed by the lack of appropriate vaccines and the virus’ ability to evolve as it invades, weakens and finally destroys the immune system. HIV, the disease which develops into AIDS, evolves so quickly that its exterior molecules are in a continuous state of transformation; consequently, the human immune system and the vaccines used to battle the virus, cannot catch up. â€Å"As it replicates within a single infected individual, HIV accumulates mutations that change the shape of its surface proteins, evolving right out from under the antibodies produced by the victim’s immune system† (National Institute of Allergy and Infectious Diseases, 2007). Due to AID’s capability of evolving at such a considerable pace, it rapidly counters medical treatments. The HIV cells which live beyond the primary drug concoction reproduce and their decedents transmit the drug resistant strain. This is the rationale for a patient’s drug therapy including what is generally called a ‘drug cocktail’ (various types of HIV drugs used together) which, in concert, act to hinder the further development of the resistant (strong) HIV viral strains. If a smaller amount of the resistant cells continue to exist, the less likelihood the disease will continue to spread. This is just one of the primary evolutionary models used by biomedical scientists to battle AIDS. (National Institute of Allergy and Infectious Diseases, 2007). AIDS made the evolutionary leap from chimpanzees to people. In all likelihood, the transfer happened by people using chimpanzees as a source for meat. The virus began in two varieties of monkeys which were eaten by chimpanzees which may cannibalize when food sources run short. A hybrid virus found in these monkeys (SIV) dispersed via infected chimpanzees and a mutated type (HIV-1) was ultimately transmitted to humans. Just like chimpanzees, people carry two variations of the disease. HIV-2 is the other and the less virulent. â€Å"Because of the similarity between chimpanzees and humans, any virus that successfully adapts to spreading among chimps would be a candidate for a further jump to humans, a potential HIV-3,† according to Paul Sharp, Institute of Genetics at University in England. (cited in Lovgren, 2003). One percent of the Earth’s inhabitants have contracted AIDS. The disease is to blame for killing of nearly three million people every year. AIDS is spread through use of use needles and unprotected sex. There is overwhelming evidence that needle exchange programs (NEPs) are very effective in preventing the transmission of the AIDS viruses yet do not promote drug use as critics of these programs contend. When first presented with this idea, Congress thought that NEPs would encourage drug abuse and they would send the message that the federal government sanctioned drug use by encouraging clean needle dispersal. â€Å"Restricting access to sterile syringes only acts to exacerbate the IDUs already desperate situation and is not in the best interest of the community regarding health, criminal or financial concerns.

Provider Roles in Spiritual Care Essay Example | Topics and Well Written Essays - 1250 words

Provider Roles in Spiritual Care - Essay Example From this discussion it is clear that the spiritual dimension of the client is strongly evident during illness, stress, difficulties, and end-life-care when people strongly needed the direction and comfort derived from their spiritual preferences. Faith and religion are essential components of a client’s spiritual dimension and health provider has the responsibility to have self-awareness of one’s spiritual preferences before integrating a non-biased spiritual care.This paper outlines that spiritual care is the most difficult task of a provider, specially the nurses. Most of the nurses lack adequate training for spiritual care giving and may influence the provision of adequate spiritual care. Healthcare providers such as nurses need to have formal education training or graduate programs in pastoral counseling or ministry in order to provide an excellent and competent spiritual care and to refer clients to other spiritual care providers as needed. Organizational team mem bers such as the Baptist Healing Trust aim to further the work of non-profit agencies in providing health services to vulnerable populations in Middle Tennessee. Members of the Baptist Healing Trust heal with love and compassionate care in accordance with the Christian tradition. In addition, staffs of the Baptist Healing Trust have the role of reiterating the importance of meeting health needs, providing human services, and balancing of excellence in skill and great compassion. The Baptist Healing Trust operates as a funding agency and requires partnership with the staff of non-profits to raise the standard of compassionate care. The Baptist Healing Trust also offers retreats, workshops, and consultation for organizational and culture change to continue the delivery of spiritual and health services to the vulnerable and underserved population of Middle Tennessee. The Baptist Healing Trust is the organizational team member of Baptist Hospital in Nashville, Tennessee. The organizatio n believed that true healing comes from deep compassionate care and charitable health care expressed through the preservation of humanity and dignity of each human being as a creation of God (Baptist Healing Trust, 2010, n.p.). The emergence of the healing hospital in Baptist Hospital follows the teachings of Jesus and the Good Samaritan. A hospital institution does not only prevent and cure diseases but also enriched the heart and spiritual needs of client. Spiritual health provider must have a servant’s heart that offers compassionate care, goes beyond the box to meet people’s needs, has commitment to organization’s values, mission, and vision, and expressed care in a continuous chain of light from care giver or provider to every patient, fellow caregiver, and one's
