Eventually, fewer and cheaper sensors should do the trick, but Google and other researchers are still working out how to combine readings from multiple sensors, and determining which sensors work best in conditions such as night driving or heavy rain.

Instead of relying solely on GPS to determine position, the SiRFstarV architecture gathers real-time information from GPS, Galileo, Glonass and Compass (when operational) satellites, multiple radio systems, such as cellular and Wi-Fi(R), and multiple MEMS sensors, like accelerometers, gyros and compasses.

The robot uses complex and multiple sets of sensors in order to do this.

While competing solutions require either two sensors or multiple chips to support pen and multi-touch, N-trig is the first company to offer both on a single chip and a single sensor, providing device manufacturers with a compact, low-power solution and paving the way for N-trig to enter the handheld market.

This new research, then, will serve multiple functions: Using specialized sensors, processors, and algorithms, the project team will measure noise in real time, tracking both the noise generated by various pieces of wave energy equipment and general background noise.
