![]() As their name implies, active tags are internally powered so they can broadcast a low level radio “beacon” carrying the asset description. Your asset tracking software must then receive the RFID reads, record that information, and update the database accordingly.Īctive RFID is the next level up in terms of performance (and cost). A pallet of tagged boxes passing through a portal-mounted reader, for example, records all the boxes simultaneously. In either case, it’s unnecessary to scan each piece of inventory individually. Passive RFID scanners can take the form of handheld units or fixed-position readers set up at entrances and exits. Under ideal conditions, a passive RFID tag can be detected and read from as far as 30 feet between the tag and the scanner, and you don’t need line of sight, so you can detect tags you can’t access easily with a barcode laser. The advantages of a passive RFID tag over a barcode are range and speed. This is an important distinction from active. Passive RFID is a standard, meaning you can mix and match tags with reader hardware. Often, passive RFID tags also sport traditional barcodes so that they can be read with both an RFID reader and – if necessary – a barcode scanner. The reader itself powers the chip, which means the passive chip lasts forever. These passive chips must be near a “reader” to be read. Passive tags have tiny internal, unpowered chips that are programmed with data, typically the ID of the asset for asset tracking purposes, but they can store additional data as well. RFID tags come in two basic forms: passive and active. The benefits of the codes are still the same, but they support easier scanning with smart device cameras. The most current barcodes are “QR Codes,” which we’ve all seen. ![]() They were magic forty years ago, but not today. ![]() Technology Overviewīarcodes are straightforward. I responded, “It depends.” But in more fully answering his question, we explored some important basics to be considered before committing to an RFID investment. As prices drop on RFID technology, the benefits become more and more realistic.Ī customer recently asked me how much he should spend on asset tags and should they do barcode, passive or active RFID. Not surprisingly, IT Asset Managers have been asking more and more about the use of RFID to reduce the time and effort tracking assets, especially by implementing RFID technology in as many places as possible.

![]() Risks associated include not being able to participate in noisy environments which can often result in depression and anxiety.” “Those with APD often develop issues with language development, hearing in noise, and sound localization. Pursuing treatment for APD as early as possible is imperative, McCullagh explains, because hearing is vital to social and educational interactions. These include environmental modifications, addressing functional deficits, and improving listening and spoken language comprehension. There are no cures for APD, but there are many treatments that aim to improve the effectiveness of everyday communication. I am hopeful that future scientific advancements will better the lives of veterans and all Americans.” Army Colonel John Dillard of HHF’s Board of Directors remarks, “It is truly unfortunate that our veterans, after making such honorable sacrifices, are forced to live with APD, often alongside tinnitus and/or hearing loss. ![]() HHF’s ERG recipient Edward Bartlett, Ph.D., explains that the changes to the central auditory system may account for the behavioral issues that veterans experience, such as problems with memory, learning, communication, and emotional regulation. An estimated 15% of all returning military personnel live with APD. Military veterans who have been repeatedly exposed to blasts are another community disproportionately affected by APD. Older adults, who are more susceptible to some cognitive decline, are also at greater risk for APD. HHF Emerging Research Grants (ERG) recipient Elizabeth McCullagh, Ph.D.’s 2017 published work in The Journal of Comparative Neurology examines the strong connection between Fragile X Syndrome (FXS), the most common genetic form of autism, and difficulties with sound localization.Īdditionally, APD is prevalent in individuals with neurological problems, including those who have experienced head injuries or strokes. APD is commonly misdiagnosed as ADD/ADHD, dyslexia, or hearing loss.ĭemographically, APD is a common secondary diagnosis for children with autism most children diagnosed with autism have auditory processing disorders or auditory difficulties. They show delayed responses to verbal requests and instructions and will often ask someone to repeat what has been said. Individuals with APD have trouble distinguishing between words or syllables that sound alike (auditory discrimination) and recalling what they heard (poor auditory memory). It is vital to review the symptoms, demographics, and treatments of APD, should you suspect it in yourself or a loved one. Individuals with APD are often unable to hear sounds as words and have learning problems, including difficulty in reading, spelling, and language comprehension. In the U.S., it is estimated five percent of school-age children, or 2.5 million children, have APD. |
