EM Project Essay: The Backscatter Scanner Today, security is one of the most important concerns in the world. Modern technologies can serve as both weapons and protection. In the public places, such as stores and airports, companies use the machines called metal detectors. They prevent from bringing in and out objects that are not allowed. However, it creates some problems, such as false alarms and uncomfortable pat-downs, and makes this technology to be incompetent. In order to solve these problems, the scientists created new full-body scanner, which is based on the use of X-rays. The most famous one is the Backscatter scanner, which is placed in many airports. The new invention solved the problems with metal detectors and gives some more
“In 2001, airline security was minimal and was the responsibility of the airline. Passengers were asked a few questions by ticket agents before they passed through checkpoints with metal detectors that were calibrated to sound an alarm for anything larger than a small caliber handgun. If an alarm did sound, security at the checkpoint would use a hand wand to scan the passenger again to determine what had set off the alarm. Bags were simply passed through an x-ray machine.... ...
One of the first new pieces of technology the TSA introduced were better screeners. A new screener known as AIT or Advance imaging technology has been created to counteract items that may have been hidden from site or...
Since 9/11 there have been nine major security changes at airports. The most important changes are the liquid ban, which bans liquids more than 3.4 ounces from being on an airplane and the body-scan machines along with the enhanced pat downs. (Seaney 1)l/ The body scan machines are x-ray machines that scan the person for anything that could be used as a weapon. Enhanced pat downs are violating to some people as they do not like their private areas searched for weapons. But these pat downs are necessary to detect, find, and remove weapons that a TSA (Transportation Security Administration) agent cannot see with their own eyes. The last important change worth mentioning is that all special items including laptops, tablets, E-readers, and all electronic items have to be checked for explosives and other threats. These changes as well as other minor regulations for passengers give the TSA an extra line of defense while screening air travelers.
At many airports across the country, passengers are sharply greeted with the hassle and headache generated by the long security lines. Many travelers complain of the continuing list of rules they have to observe and how they seem to get persistently worse. The government’s solution to the hassle and headache is full-body scanners. The government claims these full-body scanners are faster to go through versus the traditional metal detector, detect weapons and bombs easier, and reduce the stress of the long security lines. In the past, airport security has not been fully successful in protecting the country from terrorists. As a result, many terrorists without being detected are escaping and are free to pursue their assault on America. Having full-body scanners will allow for less time in security, easier detection of terrorists, and will help to protect the United States.

Driver, (2013), described the DEXA scanner as a machine that produces two x-ray beams of high and low energy levels. Much like fluoroscopy, the x-ray from the DEXA scanner comes from underneath the patient, and the scanner has a very low x-ray dose. Earlier versions of the DEXA scanner emitted radiation which required up to five minutes to scan an area of interest, but the more advanced machines can take as ...
Case Analysis of Barco Projection System: Worldwide Niche Marketing Introduction Barco N.V. was established in 1934 as a producer of radio broadcast receivers. At the end of 1970's, facing the economic recession owing to oil supply shock, the company altered its market strategy from consumer market to industrial niche market of projectors. This decision was based on firm and clear vision that Barco knew which market it had to serve. Pursuing top-of-the-line in the high-end niche market, Barco focused on R&D to retain the top quality and launched series of international expansion activities.
Apart of becoming a new patient at a dental office is taking an x-ray and some may have question along with taking an x-ray, like “will I be affected by the x-ray?” or “will I get cancer?”, “how long will it take” “are x-ray’s safe?”, the list goes on and on. So in this paper we will talk about different types of radiation affects such as affects on children and pregnant women as well as some things that may help reduce some of the radiation that may harm the human body.
Radio frequency identification (RFID) is a computerized ID innovation that uses radio recurrence waves to exchange information between an onlooker and things that have RFID gadgets, or tags, joined. The tags hold a microchip and receiving wire, and work at universally distinguished standard frequencies. Barcodes are much smaller, lighter and easier than RFID but RFID offers significant advantages. One major advantage of RFID is that the innovation doesn't oblige any observable pathway the tags could be perused as long as they are inside the range of the spectator, whereas in barcodes in order to read the barcode the barcode scanner should close around 10-15 fts. In RFID data, for example, part and serial numbers, assembling dates and support history is put away on the tags and catches which help in maintenance of equipments. RFID technology as high value for asset management and inventory systems

In reviewing my lifestyle and daily routine activities, I am very aware of how criminal think due to my career in law enforcement. I feel that the most dangerous things that I do in terms of exposing myself to criminals and entering hot-spot zones are traveling late at night or in the early morning. By being in law enforcement for the past twenty years, I try to alleviate coming into contact with a lot of people. I mostly travel early in the morning (2:00 a.m.) before the highway becomes crowded or a road rage. This allows me to enter the hot-spot zones or become victimized.
I chose this topic because I a found it as a very interesting thing which I wanted to know more about. I have been CT-scanned when I had concussion after a car accident when I was seven. Also because my father has been under a CT-scanner and a lot of my friends.
Barcodes are used everywhere around us. They are used to track products through shipment, track products at a store and speed up and enhance the checkout process, as well as allowing faster access to information. Barcodes began to be used heavily in the 1970’s. This began a great movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. However, just like all technologies, barcodes have been enhanced many times over and are being replaced by better, more efficient systems (Bonsor).
Research Paper & nbsp;& nbsp;& nbsp;& nbsp;& nbsp;& nbs R Radar is usually taken for granted in these days of modern technology. Many people do not know how radar is really used, how it works, or why we need it. People are familiar with several uses of radar, like police enforcement radar guns and radar that measures how fast a baseball is pitched in a major league game. These are only a few of the many uses radar has to offer. Radar can determine several properties of an object from a distance, such as its position, speed, direction of travel, and shape; it can also detect objects out of the range of sight in all weather conditions, making it a fundamental utility for many industries.
Physical security cannot be wholly successful without the human factor element and the active support of these user groups. For example, when the aim is to protect a critical facility from attack or to provide access control for an office building it is necessary to engage people on the proper use of any security systems that are in place, for instance security alarms. If the alarm goes off and employees have no idea what it signifies
