Accelerometers

UC3M's combined GPS unit and inertial measurement unit

Many of us use our vehicle navigation systems on a daily basis, and as self-driving cars come into common use – assuming they do – such systems will become even more important. Unfortunately, however, the GPS technology that’s integral to vehicle navigation can be thwarted by obstacles such as tall buildings. A team of researchers at Spain’s Universidad Carlos III de Madrid (UC3M) are attempting to address that problem, with a system that is said to drastically boost GPS accuracy in city driving.  Read More

A prototype DropTag

If you’re like most people, you probably just sign for a delivered parcel upon receiving it at your front door. You really ought to open it and check that its contents are intact first, but who wants to bother doing that? Well, if the DropTag makes its way into production, a quick check on your smartphone will be all that’s needed to tell you if your goods have arrived unharmed.  Read More

The POLETAP SMARTROD uses a built-in accelerometer to detect fish strikes

Imagine that you’re an angler who has several lines in the water at once. How will you know if a fish strikes on one of your unmanned rods? Well, you could attach a bell to each rod, or just listen for its reel to start running. In these days of electronic everything, however, another alternative is now in the works – the computerized POLETAP SMARTROD.  Read More

The Ten Count is a 'smart' punching bag that records the number and force of the user's pu...

Over the years, we’ve seen all sorts of performance-monitoring devices designed for the likes of runners, cyclists and even swimmers. According to Canadian boxer, electrician and boxing coach Michael Williamson, however, the only tech innovation to hit the world of boxing has been the introduction of Velcro closures on the gloves. He decided to address that situation, and invented the Ten Count smart punching bag.  Read More

An array of the optomechanical accelerometers on the surface of a microchip – the proof ma...

As any smartphone aficionado knows, the accelerometer is one of the key sensors within the device – it allows the phone to know when and by how much it’s been moved. Accelerometers also have many other applications, being major components of things like navigation systems, various automotive systems, and image stabilization systems in cameras. Now, researchers from the California Institute of Technology are developing a laser-based accelerometer, that they claim should offer much better performance than is currently possible.  Read More

UnLoc could make navigating sprawling indoor environments such as shopping malls much easi...

The commercialization of GPS technology has been a boon for those navigating unfamiliar city streets, highways and byways, but head inside out of sight of the GPS satellite signals and the limitations of the technology can quickly become evident. Other efforts to solve the problem involve the use of accelerometers, sometimes combined with magnetic field sensors, but a new system developed at Duke University promises to provide precise indoor localization using a different approach – detecting “invisible” landmarks.  Read More

Using accelerometers the Tilt of Light seesaw can show users how their movement would impa...

If you're anything like us, you probably spent many an hour in your younger days bouncing up and down on a seesaw (or teeter-totter or teeter board, depending on where you grew up. And, even now, you might fight the desire to relive your childhood and jump on one as you walk past a playground. But Melbourne-based design group ENESS has created a seesaw, which comes complete with hundreds of LEDs and a physics engine to explore the forces at work on the familiar playground staple, that might just prove too difficult to resist.  Read More

U.S researchers are developing a tiny middle ear "microphone" that could remove the need for any external components on cochlear implants. Led by University of Utah engineer Darrin J. Young, the research team has produced and tested a prototype of the device which uses an accelerometer attached to the tiny bones of the middle ear to detect sound vibration.  Read More

The MicroPEM measures air pollution, along with its wearer's activity level

For decades now, scientists have been monitoring air pollution in order to better understand how atmospheric contaminants affect our health. The gathered data can tell us the amount and type of pollutants that are in the air, which can in turn sometimes be linked to health problems in the area. What that data doesn’t tell us, however, is the effect that different types of physical activities can have on the amount of pollutants that are breathed in – if a smog warning is issued, for instance, does that mean we shouldn’t go outside at all, or just that we shouldn’t go jogging outside? A new personal exposure monitoring device, known as the MicroPEM, has been designed to answer such questions.  Read More

The mPowerPad is a solar charging device that has several functions, but lacks any externa...

With recent advances in photovoltaic panels and rechargeable batteries, it's only natural that there should now be an influx of solar-powered electronic devices. Just last week we profiled the Sunbox solar power system, that uses energy from the Sun to power three kinds of lights, recharge AA batteries, and juice up mobile phones. Now, it's time to take a look at a similar product, Third Wave Power's mPowerPad. It can charge mobile devices through its two USB ports, along with serving as a radio, flashlight, reading lamp, and even an ultrasonic insect-repelling device. As you might have noted in the photo, however, it has no external controls ... so how are you supposed to use the thing?  Read More
