...R.F.I.D. (Radio-Frequency Identification) RFID is the wireless non-contact use of radio-frequency electromagnet fields to transfer data. RFID tags are used in many industries to enter or exit buildings as well as buy certain things (mostly use in the government). It can also be attached to cash, clothing, and everyday possessions (such as cell phone, Laptops, desktop computers, tablets, etc.). Let me give you some history about where this technology came from In 1945 Leon Theremin invented an espionage or spying tool for the Soviet Union which retransmitted incident radio waves with audio information. Sound waves vibrated a diaphragm, which slightly altered the shape of the resonator that modulated the reflection radio frequency. So basically Leon Theremin created the processor for the RFID technology because it is being energized and activated by waves from an outside source. RFID uses signaling between the reader and tag is done in several different incompatible ways its all depending upon the frequency band being used. Tags operate on LF and HF bands, which use small radio waves to transmit signals. In the near electromagnetic field region the tag is closely combined electronically with the transmitter in the reader. The tag can increase the electromagnetic field created by the reader by changing the electrical loading. By changing the relative loads higher or lower the tag produces a change that the reader can detect. RFID...

...Radio frequency identification (RFID) technology is currently being used in such areas as agriculture, athletics, manufacturing, security and law enforcement, and transportation, but few applications have been developed that are related to the construction and facilities operations environment. Lack of standardisation, high costs of implementation, slow technology development and deployment risks, and the lack of skilled labour are all contributors currently preventing the adoption of new RFID technologies in the construction industry. The RFID technology can help improve data accuracy by tracking products through supply chains and by identifying products and items/objects at specific points through Automatic Identification (Auto-ID). The technology enables the detection and identification of tagged objects through the data it transmits. Objective of this topic ‘RFID IN CONSTRUCTION’ is to get an overview of the present application of RFID technology in Construction. Radio Frequency IDentification (RFID) is an old technology which was already in use for recognition for anti-aircraft gun shooting in World War. Since then RFID has been taken into use for many other purposes, i.e. securing against theft of goods, bridge crossing fees, car keys etc. The new importance of RFID is connected to certain measures which a group of the world’s biggest retail chains and brand suppliers initiated under the name of Global Commerce Initiative at the end of the 1990’es.

...Introduction: A network which freely passes desired band of frequencies while almost suppress other band of frequencies is called filter. This type of network was first examined by G.A Campbell and O.J Zobel of bell telephone laboratories. Filters are networks that process signals in a frequency-dependent manner. The basic concept of a filter can be explained by examining the frequency dependent nature of the impedance of capacitors and inductors. In filters, attenuation changes suddenly as the frequency is varied. Thus, filters have ability to discriminate between signals which differ in frequency. Filters are widely employed in signal processing and communication systems in applications such as channel equalization, noise reduction, radar, audio processing, video processing, biomedical signal processing, and analysis of economic and financial data. For example in a radio receiver band-pass filters, or tuners, are used to extract the signals from a radio channel. In an audio graphic equalizer the input signal is filtered into a number of sub-band signals and the gain for each sub-band can be varied manually with a set of controls to change the perceived audio sensation. In a Dolby system pre-filtering and post filtering are used to minimize the effect of noise. In hi-fi audio a compensating filter may be included in the preamplifier to compensate for the non-ideal frequency-response characteristics of the speakers. Filters are also used to create perceptual audio-visual effects...

...Overview For the technical requirement of the V-Bullet system we analyze the size, speed, range, security and some other major standards. The major parts of the system are the tag chips, readers, communicational network, the middleware, the server, the database, and the web-based user interface. RFID Tag For the RFID tag we decided to use a passive chip over an active one because passive tags are cheaper, they have longer lifespan and they are smaller than active tags; besides, Active tags are more useful for locations based applications and others identity applications purposes which we don’t need. This passive chip will be ensemble on a smart card with a convenient size that can fit into a wallet. The RFID tag must be in compliance with the ISO standards and will become a V-Bullet tag chip that will count with anti-cloning measures, and utilize strong encryption during communication with the reader. RFID Reader We select a reader that complies with the ISO standards and it is assumed that the readers will be used in a very noise environment that can be dusty and have high humidity depending on the location of the station, also it is important that these readers have an operating temperature between -13 and 174 degrees Fahrenheit. We know how far the reader would be from the tags but we can’t control the orientation and position of the tags; therefore, we decide to select a reader with ISO standards capable to work with circular antennas which are able...

...Running head: RADIO FREQUENCY IDENTIFICATION Radio Frequency Identification (RFID) Esther Olayinka Olagbaju November 27, 2011 Chamberlain College of Nursing Introduction Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. It is in use all around us; from the chips inserted in pets as an ID tags, to the EZPass through a tollbooth. In short, this technology does not require contact or line of sight for communication. RFID data can be read through the human body, clothing, and non-metallic materials (AIM, 2011). As a member of the committee created by the Government to investigate the potential of implanting an electronic record (EHR) into every U.S. citizen, this research will look into the benefits of this business decision to the Government, and then we will analyze the advantages and disadvantages of RFID being implanted under the human skin, which is then followed up by the laws governing this action if it can be enforced or voluntary based procedure, and finally the percentage of people that will be willing to go through this procedure. Body of Analysis Radio frequency identification technology is slick and easy to manage and also comes in three general varieties, namely; passive, active, and semi-passive (also known as battery-assisted). Passive tags need no internal power source and are only active when...

...Allaire Webster Case 1 Radio Frequency Identification Devices (RFIDs) are small chips used to track inventory through radio transmissions and are powered by radio signals similar to that of a cell phone. This technology is fairly new. In 2003 Walmart started testing the use of RFID tags on its merchandise for inventory control. RFID tags can be placed anywhere on most items and are readable even when covered with packing materials, dirt, or plastic bands. Bar codes must be visible to be scanned. A bar code scanner must be placed within a few inches of the bar code. Most RFID readers have a range of about six feet. RFID tags are small enough to be installed on the face of credit cards or sewn into clothing items. Using RFID technology can greatly benefit Harley Davidson. RFIDs can track inventory much faster. RFID offers a range from inches to hundreds of feet. With using RFIDs means you do not have to open each box. Individual tags within a carton packed in a box stored on a pallet may be read. RFID can also store much more data than a bar code. RFIDs have read and write capabilities, unlike barcodes, mistakes are less likely and maintaining accuracy is consistent. Using RFID helps manage inventory by making sure that items are stocked and available for the customers. It also improves processing time in terms of ordering needed supplies. RFIDs do have flaws. The cost of implementing RFID in a large company like Harley Davidson would be high.Harley Davidson would need...

...CHAPTER-1 INTRODUCTION The global focus on terrorism and security may have geared up following the 9/11 attacks in the USA. The risk of terrorist attack can perhaps never be eliminated, but sensible steps can be taken to reduce the risk. The issue here is how seriously do the governments take the threat of terrorism…Post-Limburg, we cannot continue to hope for the best and ignore the lessons. Our Prime Minister Manmohan Singh also mentioned in a speech last year that Indian soldiers will soon have robots assisting them to counter terrorist attack. We are yet to hear more on that thought. The word “robot” was first used in a 1921 play titled R.U.R.: Rossum’s Universal Robots, by Czechoslovakian writer Karel Capek. Robot is a Czech word meaning “worker.” Merriam-Webster defines robot as “a machine that looks like a human being and perform various complex acts; a device that automatically performs complicated, often repetitive tasks; a mechanism guided by automatic controls.” ISO describes a robot as “an automatically controlled reprogrammable, multipurpose manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications. “ Yet, all these definition do give us a rough idea about what comprises a robot, which needs to sense the outside world and act accordingly. There are motors, pulleys, gears, gearbox, levers, chains, and many more mechanical systems, enabling locomotion. There are sound, light, magnetic...

...distributors, transporters, retailers and customers. NEED OF RFID One of the key challenges many organisations face is managing the interconnectivity and collaboration between different entities of the supply chain. Seamless flow of information, tighter integration and communication between channel partners plays an important role in increasing the efficiency of any supply chain and in turn the profitability and rate of return for any business. Due to the lack of communication and flow of information between the stages of supply chain results in poor product visibility and lack of transparency in the supply chain. This occurs mainly because of the fact that each link in the chain operates as individual entity. Information technologies like Radio Frequency Identification Information (RFID) along with ERP and centralized...

...RFID stands for Radio Frequency Identification. The job of RFID system is primarily the same one that barcodes perform today, to store and provide information about a product, a pallet of goods or entire inventories. RFID systems are, however, far superior to barcodes. For example, they can process several products at once without any direct contact. And RFID tag consists of a microchip which contains a small antenna. The antenna transmits information can be stored on the microchip than on a barcode label – up to several kilobytes. The key benefit of RFID is that data no longer has to be laboriously processed using scanners. Instead this can all be done through radio transmissions, fast and at a distance. While barcodes always need to be read separately, RFID chips can be read “in bulk”, which saves time. In warehousing logistics, for example, a stock inventory can be generated at the push of a button. The possibilities for RFID in logistics are endless opening up completely new opportunities for the sector. Smart Medication: Many products have to be kept chilled during transport such as foodstuffs, liquid medication and cosmetics. An RFID sensor tag developed in the DHL innovation center and fitted with temperature sensors monitors the goods and their temperature during the entire transport process. Reading can be taken at every point of processing. Shippers, recipients or controllers can check on the condition of the products without having to open the shipment. Moreover...
