    RFID Helps to Locate Underground Infrastructure 

    3M-caution-tape-locate-underground-infrastructure-RFID-blog3M Company has claimed to have developed an effective way to locate the path of underground plastic pipes and conduits, eliminating the need for tracer wire and test stations and the problems and costs associated with them.

    Traditionally a number of techniques have been used, including tracer wires, but these have limitations. They require power to be effective and cease to operate if broken.

    The company said that its new Electronic Marking System (EMS) Caution Tape “uses a new EMS marker technology embedded into a caution tape for installation near or above the buried facility and helps provide continuous path location.” Technology embedded in the tape transmits a signal to a special reader enabling the precise location and route of the pipe or cable to be found.

    3M says the markers require no batteries and there is no need to hook up an external transmitter or search for access points. The markers work independently so that if a section of caution tape is cut or removed, the other markers on the tape will continue to provide accurate location.

    The tape comes in different versions for different types of infrastructure (water, wastewater, gas, telco). Each uses a different frequency to help reduce the risk of accidentally locating and excavating the wrong buried facilities. 3M says the tape can last for up to 50 years.

    In fact, the tape uses RFID technology, which is finding application in a broad swath of industries. If you’ve ever bought a DVD or a book and seen on the back a label with lots of wire squares one inside the other, that’s one type of RFID tag.

    Those wires are an antenna. The bit you don’t see is a microchip and that’s the heart of the device. A reader placed near the tag creates an electromagnetic field that induces a current in the antenna. This current energizes the microchip, which then uses the same antenna to transmit data stored within it. The reader collects and interprets the data.

    RFID technology works only over short ranges. As the distance increase the power that the tag is able to extract from the reader decreases, reducing the power of its transmission, which in turn has to traverse a greater distance to the reader. 3M’s EMS tape is only good for a maximum of 600mm from the surface.

    Active RFID technology is also available, but this requires an external power source, which would neutralize one of the key advantages of 3M’s tape.

    Philippines Develops RFID Sensors to Predict Meteorological Disasters 

    Philippines-sensors-predict-meteorological-disasters-RFID-blogThe Department of Science and Technology (DOST) in the Republic of the Philippines is developing a series of RFID-based smart sensors which it plans to use in the nation’s disaster prevention program.

    DOST Information and Communications Technology Office (ICTO) is developing an RFID system to monitor weather and geological conditions, as well as other aspects of its “Smarter Philippines” program, which is to generate, gather and analyze data to enable timely and effective decision making and planning.

    RFIDs will initially be put to use in DOST’s Program NOAH (Nationwide Operation on Assessment of Hazards) as automated rain gauges and weather stations. These stations transmit real-time data on the amount of rainfall, temperature, pressure, humidity and wind speed, direction, and velocity.

    Sitting astride the typhoon belt, most of the islands experience annual torrential rains and thunderstorms from July to October, with around nineteen typhoons entering the Philippine area of responsibility in a typical year and eight or nine making landfall.

    RFID in Data Logging 

    data-logging-rfid-blogRFID technology has been increasingly used in tracking inventory and equipment. This passage aims at analyzing this emerging data acquisition trend and how it’s already challenging more conventional products over a wide variety of tracking applications.

    RFID tags wirelessly send data via radio-frequency electromagnetic fields. When the tags are scanned, they send an ID number. Scanning devices don’t need a line of sight to detect RFID tags, which are attached or embedded in the tracked product. In this way, users can remotely track and identify shipments and products in many industries including food and agriculture, healthcare, and transport/logistics.

    RFID technology is especially proliferating in the supply cold chain, the logistic obstacle course which temperature-sensitive food and life science products travel from the manufacturer to the consumer. Research found that market demand for food safety products in the U.S. is expected to increase 7.3% annually to $4.5 billion in 2016.

    The study points to heightening regulatory compliance and industry initiatives as motivations for companies to invest in new food safety technology. Of course, RFID devices are forecast to be among the fastest gains in major food safety product markets as part of a growing industry trend toward supply cold chain transparency and asset tracking.

    In addition to use in the supply chain, RFID technology is also being readily adopted in other fields including the entertainment industry, with Disneyland being a successful early adapter. USA Today has reported that the Disneyland Resort has deployed RFID tags to streamline the costume checkout process and to allow effective tracking of costume pieces that could otherwise go missing or damaged. Disney also provides guests with RFID-embedded room keys and wristbands used to open doors, track attendance at safety drills, and to sort photos.

    As a more unconventional example, Barcelona’s Baja Beach Club made world news in 2004 when it began offering clients a subdermal microchip which grants access to VIP lounges and automatically runs up their bar tabs by accessing a database when scanned by staff. The chip is contained in a small glass capsule sending out a very low range radio frequency to avoid setting off security systems.

    In the near future, RFID devices are predicted to be widely adopted by vendors, hospitals, rescue organizations and in many other areas where real-time data is critical. This is definitely an emerging technology worth watching, with long-term benefits for your business or organization.
