Radio Frequency Identification (RFID) Radio-Frequency Identification (RFID) is a wireless technology that uses radio waves to read and capture information stored on a tag. A RFID reader can read the tag from upto several feet away. However unlike barcode, it does not need to be within direct line-of-sight of the reader to be scanned. There are two different type of tags: one is passive tag which collects energy from a nearby RFID reader 's radio waves; and another one is active tag that has a…

The innovation of the RFID chip or the Radio Frequency Identification has been a critical piece of technology that has been around since the 1950’s.. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip known as identity chip. A microchip implant could be used as a virtual barricade, to limit movement, and even to act as a tag for prisoners. In the realm of medicine, it could…

I. INTRODUCTION The performance of present computing systems has increased at the cost of considerably enlarged power consumption. The increased power consumption either reduces the operation time for battery powered systems, such as hand-held mobile systems, or generates extreme amount of heat and requires expensive sophisticated packaging and cooling technologies, especially for complex systems that consist of several processing units. The generated heat, if not efficiently removed, can also…

Chapter 5 Proximity Sensor 5.1 Introduction A proximity sensors is the sensor able to detect the presence of nearby objects without any physical contact. A proximity sensors often emits an electromagnetic field or a beam of electromagnetic radiation, and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor target demand different sensor. For examples a capacitive or photoelectric sensors…

In the first place let begin by saying what is the (LRAD)? It is The Long Range Acoustic Device. Which is a loud megaphone/microphone or speaker to convey important messages to individuals who makes loud noise and disturb the environment. Certainly, the LRAD is not a less lethal weapon. Of course, the LRAD is used to get the attention of a large crowd or a criminal is about to break the law by disturbing the peace. The LRAD once in operation will get the attention of the troublemaker, prevent…

microchip placed into things like: supermarket items(known as the barcode), inside people, pets, computers, phones, etc. to track them down, read their data and transfer files to and from. An RFID tag is a Radio frequency identification device(Tag You're It 72). It contains radio frequency which means anyone with an RFID tag reader can receive radio waves and see whatever the RFID tag contains. Even Though RFID’s track kids and pets that ran away from home, they should not be used because they…

Bryan Liceralde Ms. Muise ENG4U1-01 25 October 2015 Oedipus, Say Hi To Maslow Abraham Maslow 's Hierarchy of Needs is a psychological theory that intends to demon-strate what motivates others to act. One can apply his theorem to Sophocles ' “Oedipus the King”. In each level of Maslow 's pyramid, the actors have a need to fulfil and they do so through their actions. At the base of the pyramid, are the physiological needs, which are the vital necessities in-dividuals necessitate to survive.…

Please include a statement about your saving faith in Christ and when you took that step. (Please limit your essay to approximately 500 words.) Throughout my whole life, I grew up in a Christian home with a loving and supportive family that pushed me to know God better. I genuinely accepted Christ into my life at a young age and have enjoyed serving and reading my bible and learning about God. During my sophomore year, God really opened my eyes to the way I had been living for Him. In a lot of…

From a young age I’ve always had dreams, goals, and things I wanted to accomplish. My very first dream started out at the age of 6 when I saw my best friend’s new golden retriever puppy and I decided right then and there that I just had to have one for myself. It become an obsession. That puppy was the only thing I could talk about, dream about, and I just knew that I couldn’t live my life without it. I would consistently beg my dad for that precious puppy and he would always give me the…
