Confidex Launches New Survivor UHF RFID Tags, Including Battery-Assisted Version

Confidex's Survivor tag
Confidex has launched two new versions of its Survivor ultrahigh-frequency (UHF) RFID hard tags. The company says the new tags are designed for applications in which maximal read range and durability in extreme environments are key requirements. First launched in 2006 (see Confidex Launches Reusable Gen 2 Tag), the EPC Class 1 Gen 2, ISO 18000-6C Survivor tag has been a high-performance, heavy-duty hard tag used by customers in a variety of demanding industrial and logistics applications, Confidex reports, such as managing or tracking roll cages, containers and field equipment in harsh, open environments. The new Survivor is a fully passive tag about half the size of the original—weighing just 31 grams (1.1 ounce) and measuring 155 millimeters by 26 millimeters by 14.5 millimeters (6.1 inches by 1.02 inches by 0.57 inch) and offers almost double the performance of its predecessor, with the read range extended to about 20 meters (66 feet). The tag is made with an Impinj chip, either the Monza 4QT or, upon special request, the Monza 4E. A battery-assisted version, the Survivor B, can boost the read range further to up to 60 meters (197 feet), according to Confidex. It is compliant with the EPC Class 1 Gen 2, EPC Class 3 Gen 2, ISO 18000-6C and ISO 18000-6D standards, and uses EM Microelectronic's EM4325 chip. The tag's dimensions are the same as the Survivor's, but its weight is 34 grams (1.2 ounces). Survivor B is powered by Confidex BOOST, Confidex's battery-assisted passive (BAP) technology, and can be read using standard EPC Gen 2 UHF RFID readers. Because of their compact size, the new Survivor tags are suitable for a wider variety of applications, such as yard management, pipe logistics, container and cargo tracking, military applications, and managing construction or rail assets, Confidex reports. Both have an IP 68 rating, meaning they are dustproof and waterproof.

ABR Industries Announces New RFID Antenna Cables and Atlas RFID Store as New Distributor

Coaxial cable assembly manufacturer ABR Industries, based in Birmingham, Ala., has introduced a new line of antenna cables specifically designed for RFID readers. The new RFID LMR type cables are available in various lengths, with outer diameters ranging from 0.100 inch to 0.590 inch. The company also offers a variety of connectors, such as reverse polarity Type N male and female, SMA male and female, and Reverse Polarity TNC male and female. In addition, ABR Industries has announced a new partnership with RFID technology distributor Atlas RFID Store, an e-commerce store providing RFID components and hardware. According to ABR Industries, Atlas RFID has chosen to carry ABR Industries' products because it recognizes the significant difference that a high-quality RFID antenna cable can make on an RFID system's overall performance (Atlas RFID posted a blog entry about the cables—see RFID Antenna Cables: Getting the Highest Performance Possible). ABR Industries is focusing on the RFID market, and recently attended the RFID Journal LIVE! 2014 conference and exhibition—held in April in Orlando, Fla.—where it reports that it met with several RFID manufacturers and solution providers.

RFID Helps Researchers Understand Monkey Behavior

RFID has the potential to help researchers learn more about the social interactions among rhesus macaques, a species of monkey native to South, Central and Southeast Asia. In a research paper authored by Hanuma Teja Maddali, as part of the requirements for a master's degree from Georgia Institute of Technology's School of Electrical and Computer Engineering, Maddali writes that RFID could be used to better understand the social structure of rhesus macaques. According to Maddali, learning the social structure of a group by observing interactions between its members is a valuable tool for primatologists and sociologists, and is useful in learning about dominance relations that arise as a result of these interactions, as well as the correlation between the stress of social hierarchy and its effects on rhesus macaques' immune system. Traditionally, scientists must hand-label either field observations or recorded data, and then convert this information to an interaction matrix representing some relation between different individuals, Maddali explains, adding that collecting and labeling behavioral data through manual observation is an expensive process. In addition, the manual processes do not allow for continuous observation and consist, for example, of multiple samples of hour-long observations of visible individuals. RFID tags, Maddali writes in the research paper, could be used to "continuously and accurately track positions of animals with a high frequency for the automated generation of social network graphs." Some advantages of RFID data collection that he cites include uninterrupted visibility of individuals, the ability to collect a large volume of data, and a way to define social behaviors quantitatively using velocity, bearing and proximity. The RFID tags can be utilized to track how long the monkeys passively interact (doing such things as grooming each other), or how much time a monkey takes to move closer to or farther from another (such as chasing or withdrawing from each other) or to enter or leave certain areas (such as moving away from a feed area more quickly when another monkey approaches). Tracking these variables can help understand social structure, the author explains. Tests were conducted with live animals over a period of 60 continuous days in a metal enclosure at the Yerkes National Primate Research Center, located at Emory University, in Georgia. The enclosure housed six male monkeys, each wearing a collar with four Ubisense battery-powered RFID tags embedded in it. The researcher also used installed Ubisense 7000 RF readers to receive the tags' RF transmissions (beaconing approximately once per second at a frequency of 6 to 8 GHz), and that information is then transmitted to a server over a local area network (LAN). The server had Ubisense proprietary software, which calculated and logged each tag's location and body position. One drawback of this system was the inability to differentiate between playful and agonistic behaviors. "For example, chasing in the context of a time series of positions can be classified as either play or agonistic behavior," Maddali writes. "Rhesus macaques use a rich variety of visual and auditory social gestures such as yawning, lip smacking, grimacing, roaring, grunting, and squeaking. Through an additional video or audio input, the information from these sources can be combined with the approach presented in this work to provide a more detailed representation of social structure that can capture complex behaviors. The goal of future work would also be to incorporate a more general probabilistic framework to improve inferred social structure." This isn't the first time RFID has been used to study animal behaviors. The Dallas Zoo, in Texas, has tracked elephants in real time using RFID to study their behavior and determine if they are getting enough exercise (see RFID Goes on Safari).
