Full Body Scanners – How do they work?

The new full-body security scanners might become a popular alternative to body searches with the increased alleged terror threats worldwide. The full-body scanning system has taken the world by surprise in the past recent months. The most advanced method of whole-body imaging technology involves scanning the whole body through clothing, revealing both metallic and non-metallic hidden objects, including weapons or plastic explosives. The U.S. Transportation Security Agency (TSA) had already tried this concept of whole-body imaging at six airports in mid-2009 to look for threats that typical metal detectors could not find. The process to install these scanners at more airports in several U.S. cities is already heading rapidly, with the recent alleged unsuccessful terrorist attempt on a Christmas Day flight to Detroit. To combat this threatening problem and for the people’s security, the TSA has worked with two essential technologies to upgrade its passenger screening systems- the Millimeter-wave and the Backscatter X-ray.

Evolution of Solar Cells

With the non-renewable sources of nature diminishing and the global warming effect increasing, Solar energy is vital in the present times because the power demand in the world is a never-ending process. And the emergence of solar cells in the 19th century has signified the importance of solar energy today, in our lives. A solar cell is a device converting sunlight energy directly into electricity using the photovoltaic effect. The term “photovoltaic” is used since 1849, derived from Greek ‘phos’ meaning “light” and ‘voltaic’ meaning “electric” from the name of the Italian physicist Volta. Today, these solar cells or the photovoltaic cells are used to make solar panels, solar modules, or photovoltaic arrays.

Setup AVR Eclipse plugin to work with WinAVR

Probably many of you (including me) are using Programmers Notepad or AVR Studio to set up AVR projects. Each of them has advantages and disadvantages. For instance, Programmers, Notepad is a great GUI, but there are many manual routines required to start compiling projects – like setting up makefile, creating file dependencies, etc. AVR Studio is a great solution that generates makefiles automatically, and it has a great simulator for immediate debugging. So why would we need another IDE? Actually, Eclipse IDE is one of the best open-source tools that programmers widely use – so it is optimized for managing projects, code writing with auto-complete functionality. So why not give it a try. So let’s set up an Eclipse environment to work with AVR. First of all, let’s download Eclipse from https://www.eclipse.org/downloads/ site. Choose Eclipse IDE for C/C++ Developers as we want to program AVR in C. Open it (no need to install), then go to HELP->Install New Software… Click Add… and in the Add Site dialogue box, enter the URL where the AVR Eclipse plugin is located (https://avr-eclipse.sourceforge.net/updatesite/ )

Machine vision faster than human eye

Machine vision is more compact when compared with the other equipment. These equipment types are extensively utilized to develop more organized manufacturing operations carried out at the shop floor without any confusion. The machine vision system is a combination of imaging and controlling hardware that can influence the more complicated equipment utilized in manufacturing like robot-arms. The robot arms are to be calibrated concerning the positional deviation allowed in a particular workstation. Hence precise monitoring of the working of such equipment is necessary. The inspection process greatly relies on utilizing the machine vision system to mobilize better results in the overall production process. Inspection is considered to the shop floor’s life and can greatly decide the operation’s outcome in many ways. Inspecting relatively tiny and but the machine vision systems carry out active components like IC chips. They are supplied with imaging equipment like the camera to focus the change in the position of the component that is to be measured. This setup is employed to monitor the assembly lines carrying the supply of the raw material or finished goods traveling at a constant speed towards the successive workstations.

How does 3D scanning work?

Scanning is considered to be one of the most challenging jobs to be performed by equipment. It creates natural coordinates compared to the general coordinates as specified by the component’s general topography. These use specifically implicate the concept of triangulation. This concept depicts the usefulness of defining the object based on the input signals obtained by the three sensors placed at a specific angle and positional difference. The designers and professionals work 24×7, and their business is to deliver relevant data to the consumer environment. The marketing tool for the 3D scanner is a website where the professional enhance the power and image of consumer and make it easy. Graphics, contents, and colors are incorporated into a functional website for easy direction-finding. The information collected will not be revealed, disclosed, and shared with other hardware systems available with the 3D scanner. All identifiable personal data are ordered depending on the utilization of the service of the scanner. It might sound astonishing, but it is confirmed that many big software companies don’t rely on investment in new technology. For attaining adequate profit, they depend on third-person share and software.

Deadly electromagnetic waves

Science has bestowed some real bountiful things that can play a vital role in daily life. The concept of electromagnetic waves originated from the evolution of material waves. The electromagnetic waves can be produced in intricate ways that can be costly by all means. Electromagnetic waves ionize the surrounding air to carry out certain immaculate operations, creating a defining magnetic field with the available volumes of the electromagnetic waves. The dependence on electromagnetic waves has brought in particular known and unknown implications endangering the person’s life in the process. They can be helpful in creating useful cracking of the bonds, enabling better performance of the compound. They are helpful in the magnetizing and demagnetizing of the particular material based on the person’s requirement.

Blue Laser – The New Alternative Treatment for Autism Care

Life as a human being is full of many unpredictable events. We always have the risk of getting numerous types of diseases at any time. Although health and medical’s technology have been growing in leaps and boundaries, many conditions remain uncured until today… A recent study has been shown that the blue laser has the power to cure autism. A research group from MIT had carried out an experiment where they shined the blue laser onto a live mouse brain directly. They discovered that the gamma waves are triggered in the mouse’s brain, where the primary brain wave can be used to cure autism. The research group called the specific neurons that trigger gamma waves “Fast-spiking interneurons.” Although scientists have known about gamma waves for over decades, they’ve lacked the technology to prove their theory. They also mentioned that people with autism are mainly caused by the inadequate gamma waves in their brains. One of the best solutions to overcome this problem is to trigger gamma waves in people with these psychiatric conditions as soon as possible! More research has to be done before the blue laser could cure autism in the future. [discovery]
