Last year, we told you about a smartphone-based system that can be used to find your missing stuff, known as BiKN. It consists of an electronic case that the phone slides into, which tracks the whereabouts of paired radio frequency tags that the user attaches to their car keys, purse, children – you name it. The phone displays the location of the sought items, or can sound an alarm if one of them gets too far away. Now, it looks like BiKN might have some competition, in the form of the similar-but-different U Grok It.  Read More

A new type of radio frequency identification (RFID) tag doesn't have an antenna of its own...

Radio frequency identification (RFID) tags are definitely a handy way of tracking shipments. Instead of simply crossing their fingers and hoping for the best, importers and exporters can check the location and condition of shipped items in real time, by remotely accessing the data being transmitted by RFID tags attached to those items. Unfortunately, many such tags don't work on metal objects such as shipping containers or oil drums, as the metal interferes with the functioning of the tags' antennas. A new tag developed at North Dakota State University gets around that limitation, however - it uses the metal object as its antenna.  Read More

New media entertainment company, d'strict, is pushing the concept of virtual reality to a new level with the "Live Park 4D World Tour," a new theme park that recently opened in South Korea. The park is comprised of 65 different attractions over a 10,000 sq. foot (929 sq m) space, which houses several large interactive displays as well as some installation art pieces. Visitors wear RFID wristbands that allow the displays to identify them, while Kinect sensors detect their movements, voices, and faces. Many of the attractions center around having users create an avatar of themselves that they can interact with and take on a virtual adventure, which is portrayed using 3D video, holograms, and augmented reality technology.  Read More

Detecting explosives is a vital task both on the battlefield and off, but it requires equipment that, if sensitive enough to detect explosives traces in small quantities, is often expensive, delicate and difficult to construct. Researchers at the Georgia Tech Research Institute have developed a method of manufacturing highly sensitive explosives detectors incorporating RF components using Ink-jet printers. This holds the promise of producing large numbers of detectors at lower cost using local resources.  Read More

The VIATAG system's RFID transponders allow drivers to use car parks without having to mak...

Car parks can be a hassle – you have to roll down your car window and reach out to get a ticket from the dispenser on the way in, and then have to reach over and pay the cashier on the way out. The engineers at Germany’s Fraunhofer Institute for Material Flow and Logistics, however, have come up with something easier. They’ve developed an RFID (radio-frequency identification) tag system that allows drivers to pass unimpeded in and out of car parks, with parking fees being automatically deducted from an online account.  Read More

Project leader Ollie Szyszka, with one of the electronically-tagged cows

With diseases such as Foot and Mouth, TB, and of course Mad Cow still presenting a danger to cattle, it’s of the utmost importance that farmers monitor the health of their animals, and immediately proceed to isolate any that might be showing symptoms. If you have a herd of over 500 cows, however, keeping track of individuals can be rather tricky. That’s why scientists at England’s Newcastle University have developed electronic ears tags, that they’re trying out on a herd of test cattle.  Read More

Ortho-Tag is a system in which information regarding orthopedic implants is stored on a ch...

Over the years, New Jersey orthopedic surgeon Lee Berger became frustrated with the lack of information that patients had on prosthetic devices that had been implanted within their own knees, hips, feet, or other parts of their skeleton. In order to gather data such as the size, model, age, serial numbers or manufacturers of these implants, either X-rays or extensive paper trail hunts were required. His new product, the Ortho-Tag, is designed to address this problem. All of the vital data regarding an implant could be obtained by placing a probe against the patient's skin, plus information on the health of the surrounding body tissue would be provided.  Read More

The Lovers Box opens like a book to display screen in portrait orientation

Adding that spark of magic to digital devices is the secret ingredient in the success of many products and services. That spark is often personalization; the concept of a device or service being mine and for only me, building an attachment to transcend the mere bundle of plastic and circuitry in front of you. Researchers at the University Of Newcastle have been working on ways to make more emotionally meaningful forms of digital communication by producing what they are calling "Lovers' Boxes". Resembling an antique wooden jewellery box, each conceals the latest technology to play back messages recorded by a loved one.  Read More

Green Goose awards lifestyle points for carrying out everyday tasks you've set yourself

How many times when you were a kid complaining about doing something boring were you told to make a game of it? If your parents and teachers were anything like mine, probably quite a few. Looks like the folks behind Green Goose might have copped the same treatment – they have come up with a system that turns boring tasks like brushing your teeth and exercising into a game that awards the 'player' with lifestyle points for completing various everyday tasks, in much the same way as players earn experience points in role playing games.  Read More

Technology is delivering a array of health monitoring systems that can record a person’s blood pressure or perform an ECG on the go. Now researchers have turned their attention to monitoring cardiac pressure, an indicator of heart problems that can normally only be measured using an invasive procedure known as a coronary angiography.  Read More
