Charging of cell phone battery is a big
problem while travelling as power supply source is
not generally accessible. If you keep your cell phone
switched on continuously, its battery will go flat within
five to six hours, making the cell phone useless. A fully
charged battery becomes necessary at times when
you need to use them. Here is a simple charger that
replenishes the cell phone battery within two to three
hour. This device was accomplished by Max Donelan.
He invented a knee braces to harness the human power
which according to him is believed as much as 1000
kg battery can provide. This device is strapped to the
knee of the wearer and as he walks using the principle
of energy conversion the device converts the kinetic
energy into electrical energy which is sufficient enough
to charge ten cells at a time.
Index Terms—energy resources, knee braces, electrical
energy, kinetic energy.

VII. CONCLUSION
With natural resources depleting, it is vital for
human survival to look for alternatives, be it
windmill to harness the wind energy, Solar panels to
use them for heating and generating electricity etc.
No one can deny the fact, recharging our electronic
device keep us ahead in the digital era. At some
Smartphone's are unquestionably one of the most useful devices of the 21st century but they continue to have one critical flaw- battery life. unpredictable battery lifetime issue from multitasking can have a significant negative effect on the availability of Smartphone devices.
Hard of Hearing patients need something that will suit there financial goals in the long run, be less of a hassle to worry about and enhance their hearing all at the same time. We propose in creating a Battery-Less-Hearing Aid and believe that it is the best option to go because Hard of Hearing patients will never have to worry about recharging batteries or buying new ones all the time like you do with our current hearing aids that are available in today’s society. On top of that our patients would save money at the same time by never having to buy batteries and will still able to hear just like they would with a hearing aid that is battery operated.
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.
Nike has found a way to make smart phones work with a bracelet to track all of your physical activity each and every day. Now that is sweet, not is Nike making great sporting and everyday clothes, but they now have found a way to make your phone ...
Buzz; Buzz. *teen picks up phone* next thing you know the family is planning the teens funeral or trying to figure out they are going to pay for the hospital bills. Many people could argue that the texting and driving law should be for everyone, this includes adults and elderly people. I believe that the law should only include teenagers because it effects them at such a young age. It will train their brain not to pick up that phone every time it goes off. Almost every teen now and days grew up with a phone, thee adults however did not. Teens are so us to just picking up their phone whenever it goes off. Adults should know better not to text and drive, they shouldn’t need a law that states not to text and drive, teens however they need that
In this recent century, there is ease into taking our technology as something for granted. After all, technology has opened up our abilities to instantly connect to the other side of the world, instantly retrieve information from the Internet, and instantly listen to digital content if desired. However, while a cell phone, laptop, and iPod has many differences from one another, all of those three devices share one item in common at the very least and that is a Lithium-Ion Battery.
Have you ever wondered how some athletes have gotten so good at a certain sport? Have you ever thought about what they did in order for them to get this good? For some the answer is simple; workout and train. But for others the answer is different; the use of performance enhancing drugs such as steroids. There are some people that argue that steroids should be legalized and allowed in professional sports. Other people argue that steroids should not be allowed. Today I am going to state my opinion and justify my reason. Steroids should not be allowed in professional sports because it can be very dangerous to the athlete’s health, it is a way to gain and un-fair advantage and it can be dangerous in both social and physical aspects.
Over the years, the cost of college tuition has been one of the central issues limiting students, like me, from obtaining the best education that one could receive. Usually, this results in students settling for a school nearby rather than being able to have the choice to go to the best one in which they were accepted into, due to such skyrocket prices. Much of this problem or concern has to do with out-of-state tuition being much higher than in-state tuition, sometimes almost doubling the price of in-state tuition! Therefore, students are more pressured to remain in state rather than go to out-of-state schools that may offer a better education.
High school education is for students to learn the basic information that is needed to prepare them for college. It is critical for students to feel that it isn’t a waste of time for them to wake up and go to high school everyday. Is it right for students to not come to school because they feel high school is a waste of their time? Majority of students has also felt that the courses they are attending aren’t giving them enough information that will be useful beyond high school. Shouldn’t students be in classes that will benefit them in the future? Should students be able to know what might be their strengths, and weaknesses in the courses that are required to be taken for a certain major? High schools should offer useful courses because it
Cell phones have gradually become a large part of a person’s life. A person’s day usually starts and ends by using a phone. People may argue that this is false, but for many, their alarm is on their phone, and that is the first sound they hear in the morning, followed by the action of turning it off. Even looking at the time of day requires someone to turn on their phone. Even though a cell phone might be the most innovative item on the market that makes everyone’s lives easier, it could end up harming them from many different aspects. This paper will focus on scientific, economic, and environmental point of views.
If there could be a law that saves lives, it should be placed. Texting and walking has shown concern for citizens safety while crossing streets. The question of having a law to stop people from being on their phones while crossing a street has been a conversation topic. The questioning of having the need to place a law that saves lives should not even be an argument. Texting and walking has created a distraction for people to realize what is going on around them, which is very dangerous.
Even as I sit here typing this paper, my own shiny, rectangular piece of molded plastic and metal lies inches away from my fingertips, beckoning me to use it. Looking out the window, one of the first sights I see are people walking with one hand up to their ear, evidence this technology is in use. I can count on one hand the number of adults I know who do not own one these mobile devices. People are now able to be virtually accessible almost anywhere at any time.
Storage of electrical energy is very important in many applications especially electrical appliances which require mobility or short burst of energy over a short duration of time. There had been many technologies developed to emulate characteristics of an ideal power supply which can store large amounts of energy, providing good power output as well as being able to be charged and discharged rapidly without deterioration of any type. A typical power storage device can be characterized by its power density and its energy density, noting that with our current technology, none which can achieve the best of both.
Raise your hand if you’re one of 44% of Americans that sleep next to their phones at every night. It’s true, so many of us are dependent on our mobile devices, that psychologists are now calling it the “Invisible Addiction”! Since its invention critics have debated every inch of the cell phone. From its usefulness and size, to its effects on health after prolonged usage. The conversation has since shifted. The cell phone market today is flooded with a plethora devices to choose from, sporting top of the line materials and industry leading software, but this just scratches the surface. With over 968 million worldwide smartphone sales in 2013, consumers are feeding into the latest technology that the market has to offer. Though they may become
Cell phones represent a type of technology that has been around for more than over fifty years; it has only been recently that many people began to use cell phones as a major part of their everyday life. In the past cell phones were for business people to conduct their business, but in today’s society every one owns a cell phone. Cell phones are interesting, useful and also play a major role in our life’s bringing people closer and keeping in touch with one another. Most people do not know and understand the physics of a cell phone. Cell phones are also known as cellular phone, hand phone, and commonly known as a mobile phone. A cell phone is an electric device that can make and receive calls, over and automatic repeat request (radio link petrol -RLP) used over wireless air interdace.it us a portable telephone that uses and receive phone signals.it also divides that earth into small regional called cells.in the resent estimates there are over 190 million people using mobile phone. One of the primary health concerns is the impact of cell phone radiation, by radio waves by which it operates.
