...chief problem with the sensor technology is how to find an inexpensive way of transmitting the sensors' data to computers. Sensors currently rely on batteries that often need to be replaced, and they require a fair amount of bulky hardware. "Right now, it wouldn't be a cost-effective way [to monitor changes] on structures like bridges," Farrar says. So his team is testing small, remote-controlled helicopters that would send a pulse to provide power to the sensor, take a reading and send it back to the helicopter's computer and then transmit the data to officials...
Chris Goggin, who heads his own research and engineering company in Wilmington, N.C., is working on a different method of transmission; a radiowave-powered switch that can wirelessly control small devices such as locators or sensors. Goggin, a semi-finalist for the History Channel's annual Modern Marvels Invent Now Challenge this year, says state officials could get data from the sensors directly at the push of a button and a radio signal would act as a transmitter, putting the bridge's sensor information into an e-mail sent straight to their inbox. "You wouldn't need helicopters or lights...
Harvard researchers and a local technology company are developing a network of weather sensors that will make the Cambridge climate one of the most closely studied in the country. CitySense, a project headed by Assistant Professor of Computer Science Matt Welsh, brings Harvard researchers and BBN Technologies engineers together to create a unique wireless network that can be used for research ranging from high school projects to doctoral theses. Cambridge will be the first city to install the sensor nodes, which will be placed on or inside small boxes, on its street-light poles next year. “CitySense...
...master's TV remote control fixed to the lip of a basin. It has one button to turn on or increase the water's flow, one to turn it off or down, and one each to make it hotter or colder. Behind the minimalist exterior is a programmable sensor that allows the user to get precisely the temperature desired with a single push-er, caress-of a button...

Behind the minimalist exterior is a programmable sensor that allows the user to get precisely the temperature desired with a single push - er, caress - of a button. Nouvel can pick his tasks, so why bathrooms? "It turned out I have something to say about taps," says Nouvel, 61. "We have technology now that lets us minimize our gestures...
