"I can see what he sees, which sensors are being activated, what emotions he's showing," he said.
Beginning in the early 1950s, then, the U.S. and British navies began to investigate passive sonar, in which sensors detected noises emanating from the submarine itself.
A similar approach is used with external electrocardiogram machines in hospitals in which sensors are placed on the skin to detect heart attacks.
The optimization relies on different levels of decision: choosing which sensors are masters and balancing the load among sinks.
We consider networks in which sensors are not aware of their locations or the relative directions of their neighbors.
By the 10th session we'll be ready to try out a kind of video game, in which sensors on my groin measure whether I'm contracting the muscles enough to stay above a running orange line on the computer screen.
Researchers have already experimented with such a device in New York last year, in which sensors are attached to the tree and then the recorded sounds are fed through a computerized neural network.
In lieu of gauges or hard buttons, the entire dash is a pane of glass, behind which sensors detect the proximity of a user's hand and can intuit a command without the driver's ever laying a finger on the glass.
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.
Boeing chief executive Dennis Muilenburg said Sunday that his company is finalizing software updates and pilot training protocols to address problems that have emerged "in response to erroneous sensor inputs". He did not specify which sensors.
Once under the Arctic ice, navigation depends on an inertial system in which sensors record every motion of the submarine in a computer that keeps track of the ship's position.
