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.
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?
Jawbone has built a reputation for producing slickly designed Bluetooth headsets and the company's latest flagship model - the Jawbone ERA - continues that tradition. The ERA is an exceptionally lightweight package that has 25 percent more audio output than previous models, an updated version of NoiseAssassin noise cancelling technology, an onboard processor and flash storage, but its the first ever inclusion of an accelerometer in the unit that has really grabbed attention. So is this a case of tech for tech's sake or does it actually add up to a better headset? We've been putting the ERA through its paces to find out.
According to a 2008 study by the Swedish National Road and Transport Research Institute, about 20 percent of all road traffic accidents are caused by driver fatigue. Tired motorists are also eight times more likely than rested motorists to get in an accident, displaying driving abilities similar to those of someone who is intoxicated. The problem is, we often don’t know when we’ve reached that “too tired” state – a situation that the Anti Sleep Pilot was created to address. The Danish-designed device sits on your dashboard, monitoring you and your driving conditions, and lets you know when it’s time to pull over and take a ten-minute rest.
The Q2 Internet Radio
asks users to boil down the thousands of available online radio stations and choose just four. This may appear to limit choice, but actually reflects the fact that most of us only regularly listen to a few stations anyway. The device also does away with display screens and has only one button – an on/off switch. To change a station, you tip it onto another of its sides. To increase volume, you raise the front of the unit, and raise the back to lower it. I've been given the chance to take one for a test run, so read on for my thoughts.
capabilities of modern cameras means photographers no longer have to go through the boring task of jotting down the location of a picture on the back of photos. Unfortunately, interference when taking pictures indoors or even outside amongst a forest of skyscrapers can render the geotagging feature inoperative. The latest model to join Casio’s EXILIM
Hi-Zoom lineup, the EX-H20G, overcomes this problem by using a Hybrid GPS system that combines GPS with a three-way accelerometer and direction sensor to track a user’s last known satellite-acquired position against map data stored in the camera’s memory. It then checks every 10 minutes until it can reconnect to a satellite signal.
Micro electromechanical systems, or MEMs
, are promising in an array of high-tech applications. However, the accuracy of conventional techniques to gauge the force and movement of tiny objects containing components so small they have to be measured on the scale of micrometers or nanometers are typically off by 10 percent or more because of their inherent uncertainties. A new technology enabling MEMs to "self-calibrate" could overcome this problem and make possible super-accurate and precise sensors for crime-scene forensics, environmental testing and medical diagnostics.
It seems like just yesterday Oregon Scientific was offering up its ATC2K actioncam
, and now it’s all the way up to the 9K? They grow up so fast! Like its immediate predecessor, the ATC5K
, the ATC9K features a built-in color LCD screen. Unlike it, however, the 9K shoots full 1080p HD, is waterproof down to 20 meters/60 feet (the 5K only goes down to 3 meters/10 feet), has a 130-degree field of view, includes a remote, and
it can embed G-force data on your footage.
No one believing your tales of gnarly moves pulled on some off-piste run? Can’t convince your friends you nailed a Spock 540 One Handed when no one was looking? Now you can prove it (or get a harsh dose of reality) with the ShadowBox – a "personal 3D sports recorder" that attaches to your extreme sporting implement of choice and uses GPS and G-Force data to record a "ride path" of all your extreme sporting moves. Ride data can be viewed immediately on the device or uploaded to a PC or Mac to analyze all your extreme sporting moves in 3D detail.
Obesity rates are on the rise in most western countries where sitting at a computer all day (and sometimes into the night) is commonplace. Low activity levels, in many cases, combined with poor diets, have been blamed for almost two-thirds of Americans being overweight or obese. To help address the problem, health researchers have developed an iPhone app designed to monitor your physical activity and motivate you to do that little bit more.
