Ed Yeates' Clip on iWalker
This video clip of iWalker was featured on Channel 5 KSL TV, Salt Lake City, Utah on March 4, 2008 by Ed Yeates.
This video features iWalker, a multi-sensor rollator-mounted wayfinding system for the elderly. The sensor suite consists of an encoder, a digital compass, and an RFID reader-antenna unit. The RFID antenna is attached to a PVC pipe in front of the walker, about 5 cms from the floor. It reads passive RFID tags in smart mats. A smart mat is a carpet with a grid of RFID tags...

Radio-frequency identification (RFID)
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized...

Prototype UHF RFID tags designed within a laboratory course in the ECE Dept of AUTh
In the context of a prototype Antenna-Lab, undergraduate students of the Dept. of Electrical & Computer Engineering of AUTh designed some prototype UHF RFID tags under specific guidance and size-constraints. The antennas were constructed and attached to a passive RFID chip with wake-up sensitivity threshold equal to -14dBm. All tags demonstrated impressive range performance (considering the tag's sensitivity), in the order of 7.5m to 8.5m, in the laboratory environment, which indicates that...

RFID Display of Semi-Passive Tag Hack
The display model testing for a presentation at Purdue University's Springfest 2012. A semi-passive tag has a simple switch integrated into the antenna circuit to prevent eavesdropping (and having to carry a 'as seen on tv' steel wallet). Seen is a 125kHz circuit harvested from a standard passive card interfaced with a tactile swtich, rapid prototyped with my RepRap Prusa.

iWalker: Multi-Sensor Rollator for the Elderly
iWalker is a proof-of-concept multi-sensor rollator-mounted wayfinding system for the elderly. There is a laptop with a contour map of the USU CS Department. The blue circle on the map is the current location of iWalker.
The sensor suite consists of an encoder, a digital compass, and an RFID
reader-antenna unit. The RFID antenna is attached to a PVC pipe in front
of the walker, about 5 cms from the floor. It reads passive RFID tags in
smart mats. A smart mat is a carpet with a grid of...
