What Is An Atomic Clock?

The atomic clock is a kind of clock that utilizes atomic resonance frequency as its timekeeping feature. These clocks show the exact time and frequency standards and are identified as the primary standards for international time and manage and organize the frequency of the television broadcasts and GPS satellite services. The atomic clock uses the resonance frequency of atoms as its resonator. A resonator is operated by the frequency of the microwave electromagnetic radiation absorbed or emitted by the molecule or atom’s energy change. Thus an atomic clock generates standard frequencies. These are installed at various sites to show time signals. Alpha navigation transmitters and LORAN C. Atomic clocks are very useful in long wave and short wave broadcasting stations to deliver an exact frequency that can act as the standard frequency. Also, atomic clocks have been used in a long-baseline interferometer in radio-astronomy.

Technologies That Fight Global Warming

Global warming is a significant threat to people and the earth. It is an increase in the earth’s surface air and the oceans. Earth now finds it difficult to breathe because of the concentration of greenhouse gases. Greenhouse gases are essential to the earth’s environment. It effectively traps heat in the lower atmosphere and radiates the heat the planet needs. Without greenhouse gases, our earth’s temperature would be 0o F or -18oC instead of 57°F or 14°C. Are we aiding in the enhancement of the greenhouse gases or going against it and making it worse? Man has caused the most damage to greenhouse gases. Through the combustion of oil, coal, and gas, human activities have increased the concentration of greenhouse gases in the atmosphere. Pollution is the biggest human-made problem. Another main problem the cause of global warming is population. To fight global warming, scientists have found different ways to solve the problem. The use of technology in fighting global warming is one of the means to reduce global warming.

Nanotechnology provides the user to play with a variety of components present in the world. The nanoscience engraves certain unique features associated with the development of science. It revolves around certain intricate topics such as manufacturing at the nano level and then engineering components at the nano level. This may involve an improved skillset from the working community. The works of various researchers involve the use of nanotechnology in day to day life. The people worldwide may appreciate the use of Nanotechnology in production of carbon tubes used for various engineering applications if it is feasible. But it is known that nanotechnology’s use to produce such a small component is practically impossible, but this statement is proved wrong in recent years.

Mind/Though Controlled Robot Arms

The human mind is an excellent feature of God’s creation. Only with our mind, our body parts are controlled and made to do certain activities. Thus, when a person is brain dead, he cannot move his body or lift his arms and legs. The mind is the main thing needed to make the whole body function more effectively. Now, according to the new research study, the human mind can control robot arms. Robot arms are fitted to persons who have lost theirs in an accident or through some other means. For those who are disabled, just a mere robot arm which does actions only when a button is pressed doesn’t help. To make a more efficient and effective robot arm, scientists have created a robot arm that can be controlled by the person’s mind. The mind is used now though to control robot arms. The Rehabilitation Institute of Chicago introduced the first woman to be fitted with robot arms or bionic arm technology. This woman met with an accident, and her left arm was amputated from the shoulder. She has now been fixed with a robot arm with which she can now think and make the arm do the things…

Invisibility Technologies

Invisibility is often used in movies to express a magical feeling in the minds of the viewers. The word ‘invisible’ itself is magical and needs a lot of connotation. When something is invisible, it creates a magical effect and a questioning mind, and this makes the viewers probe into the field of invisibility technology. Really is there something called invisibility cloaking? Fictional movies have used invisibility cloaking to make something disappear for some time, and when the cloak is removed, the thing or the person appears again. In 2008, a physicist named Michio Kaku prophesied that a feasible invisibility device like the ones used in Star Trek could emerge from research laboratories. He also quoted David Smith of the Duke University who had used meta-material to bend light around an object. He also quoted that German scientists have found that a meta-material can make the red light around the object.

Fuel Cell Technology: Advantages and Disadvantages

In this age of technology, there is a development every minute in almost all the fields in one regard or the other. Such a significant result in a lot of alternate energy is the Fuel cell. A fuel cell, in simple terms, is an electrochemical energy generating device. It has been one of the most fascinating and interesting aspects of today’s world’s technology. Many things are yet to be developed in this field, and there are a huge scope and application for these Fuel Cells. These fuel cells are being under research by many people all around the world. Construction and Working There are many different types of fuel cells. But the basic construction and working of a fuel cell are the same, and the concept behind it is also the same. The Fuel cell works on the principle that energy is produced when some chemical reaction occurs. If this energy can be tapped, it can be converted into practical means. In a conventional fuel cell, the reaction occurs between hydrogen and oxygen, and water is formed. This is the primary chemical reaction that happens, and energy produced by this is tapped through proper channels and used for several applications.…

Automated Guided Vehicles

Automated Guided Vehicles help transport the raw materials, semi-finished products, and finished products within a workplace. Initially, in any industry or a workplace, the materials are transported from one work station to another work station manually or by using a vehicle that the human operates. Because of the manual interaction, the time taken for transporting the materials is high, and because of the increased time, the production rate of an industry comes down. To increase the production rate and utilize the resources like labor, machine efficiently in an industry, Automated Guided Vehicles have been brought into existence. The Automated Guided Vehicles cannot be installed in the workplace as such. It needs a lot of planning and design. This is because the Automated Guided Vehicles installation is costlier, and once installed, it would be difficult to change them. Thus, before installing the Automated Guided Vehicles, the Automated Guided Vehicles’ installation and movement region should be pre-determined. The layout of the company plays a vital role in the Automated Guided Vehicles system installation. Automated Guided Vehicles’ primary purpose is to reduce the travel time of the raw material or the workpiece. So the shortest route between the workstations has to be identified,…

The Multipurpose Controllable Power Outlet

For all the home hobbyists, you knew that dealing with microcontrollers is a fun thing. Once you have been hooked with it, there was no turning back. Do you know that a microcontroller’s GPIO (General-purpose input/output) pins cannot handle higher power requirements? An LED was easy enough, but how about the large power items such as light bulbs, toaster ovens or blenders that required more circuitry? In this case, a relay is wanted in this situation. However, building a 5V controllable power outlet can be handy for many applications; thus a relay is a perfect choice for this project! For your information, a relay is a large mechanical switch, where the switch is toggled on or off by energizing a coil constantly. By applying the relay in the project, it will ensure your safety. Let’s take an example. If you have 120VAC running through the paddles, you don’t have to worry that 120VAC will sneak back into and vaporise your microcontroller connected to the coil, as the paddles are capable of carrying substantial currents! Furthermore, you can use the relay to control a DC motor or an AC lamp if you want to.
