Using GPS to measure changes in sea level

Measuring sea level is not only an invaluable tool for pilotage, navigation, aeronautics, cartography, sea charting, and geology, it’s also a fundamentally important metric for measuring possible evidence of climate change, and for measuring the direction, extent and rate of such change. Johan Löfgren and Rüdiger Haas of Chalmers University in Sweden have developed a new way of measuring sea level that uses satnav signals for constant, real-time monitoring that promises new insights into many fields, including climate change.

Hi-tech glasses aim to assist the blind with directions and obstacle detection

Researchers from the Center for Research and Advanced Studies (CINVESTAV) in Mexico have developed a pair of glasses that use a combination of ultrasound, GPS, stereoscopic vision and artificial intelligence to help the visually impaired to navigate their environment. The device, perhaps the most sophisticated of its kind, is slated to reach mass production early next year and will likely cost up to US$1,500. Read More

Galileo-LawinenFon turns a smartphone into an avalanche transceiver

In October of last year, the Canadian Avalanche Centre (CAC) issued a warning about the dangers of relying on smartphone apps that were being marketed as economical alternatives to avalanche transceivers. But a new smartphone app and add-on hardware component could provide an alternative that is not only cheaper than dedicated avalanche transceivers, but also provides additional functionality.

Digital positioning shoes keep track of firefighters

Disorientation inside smoke-filled and unfamiliar buildings can be a major obstacle for firefighters – and it's not as if they don't have enough to worry about already. Researchers at KTH Royal Institute of Technology in Stockholm have addressed this problem by developing fancy footwear that allows firefighters to be tracked in places where GPS fails, including up to 25 m below ground.
