  • Radio Frequency Identification (RFID)

    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…

  • Inductive Proximity Sensors

    held to the ear during a call. They are also used in the machine vibration monitoring to measures the variation in distance between the shaft and its support bearing. This is common in the large steam turbine, compressor, and motor that use sleeve type bearing. 5.2 Inductive Proximity Sensor A proximity ( inductive ) sensors is an electronic proximity sensors which detects metallic object without touching them. The sensor consist of the an induction loop. Electric current generate a magnetic…

  • The Radio Frequency Identification

    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…

  • Rfid Disadvantages

    3.8: Benefits and Limitations of RFID: Though RFID is not likely to entirely replace commonly used barcodes in the near future, the following advantages suggest to additionally apply RFID for added value of identification: • Tag detection not requiring human intervention reduces employment costs and eliminates human errors from data collection, • As no line-of-sight is required, tag placement is less constrained, • RFID tags have a longer read range than, e. g., barcodes, • Tags can have…

  • Resident Evil: Extinction Analysis

    Resident Evil: Extinction. It’s a very entertaining action packed movie, but it also gives a rough draft about what are radio-frequency identification chips (RFID Chips). Radio frequency identification chips uses electromagnetic fields to automatically identify and track tags attached to objects that contain personal information. In the movie, the used a devices very similar to radio-frequency chips to track the main character Alice. Alice was an ordinary girl until the antagonistic Umbrella…

  • Essay On Nanotechnology

    Imagine that, in the near future, you need lung surgery. Currently, this type of surgery would be very invasive and very risky to do surgery. But, due to advances in nanotechnology, the surgery could be quick and painless with almost no inherent risk and would not be nearly as invasive. Nanotechnology isn’t exactly new; it has been discussed and studied for many years. However, advances in this field have led to new and exciting discoveries. Surgeries, for example, are one of the things to which…

  • Microchips Disadvantages

    Microchips are smaller than regular sized chips and typically can do the same amount of work, if not more. According to the Merriam-Webster dictionary, a regular chip is “a small wafer of semiconductor material that forms the base for an integrated circuit.” (dictionary) Although microchips seem like a better way to go, there are a few minor complications in this idea, such as the complexity of the circuits, the cost of the materials to make produce it and the function that is required of this…

  • The Pros And Cons Of RFID Chips

    life. Everyone has seen Windows 10 and the new iPhone 6s+, but not many people have noticed the small and silent but (metaphorically) deadly technological “predators” that are spreading quickly throughout humanity: RFID chips. RFID stands for Radio Frequency Identification. RFID is a small piece of equipment that utilizes electromagnetic fields to transfer data between the chip and a receiving device. General RFID chips are a breach of personal privacy and should not be used in any circumstance…
