Hothead Technologies has developed a system that can sense and warn a user of heatstroke. In this video, an RFID transmitter is fitted in a headband and a white temperature-sensing patch touches the wearer’s forehead. Readings are beamed to a PDA (not shown). When the wearer’s temperature hits 102.5 and stays there for 20 seconds, an alarm sounds on the PDA.
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is a new satellite developed by the European Space Agency to measure the earth’s gravity field. Here, researchers discuss the mission and how it will impact climate-change research.
The New York startup, Sense Networks, has developed algorithms that can identify distinct types of behaviors of people in a city, and group them into so-called tribes. The first animation shows the changing whereabouts of these tribes over the course of an evening in San Francisco and the second animation depicts the process of identifying the primary tribes visiting the top 200 nightlife destinations during a certain period of the night.
