Confined to the basement of a CIA secret prison in Romania about a decade ago, Khalid Sheikh Mohammed, the admitted mastermind of the 9/11 terrorist attacks, asked his jailers whether he could embark on an unusual project: Would the spy agency allow Mohammed, who had earned his bachelor’s in mechanical engineering, to design a vacuum cleaner?
The agency officer in charge of the prison called CIA headquarters and a manager approved the request, a former senior CIA official told The Associated Press.
Mohammed had endured the most brutal of the CIA’s harsh interrogation methods and had confessed to a career of atrocities. But the agency had no long-term plan for him. Someday, he might prove useful. Perhaps, he’d even stand trial one day.
And for that, he’d need to be sane.
“We didn’t want them to go nuts,” the former senior CIA official said, one of several who spoke on condition of anonymity because they were not authorized to talk about the now-shuttered CIA prisons or Mohammed’s interest in vacuums. (AP Photo)
[A] system being developed by Dina Katabi, a professor in MIT’s Department of Electrical Engineering and Computer Science, and her graduate student Fadel Adib, could give all of us the ability to spot people in different rooms using low-cost Wi-Fi technology. “We wanted to create a device that is low-power, portable and simple enough for anyone to use, to give people the ability to see through walls and closed doors,” Katabi says.
The system, called “Wi-Vi,” is based on a concept similar to radar and sonar imaging. But in contrast to radar and sonar, it transmits a low-power Wi-Fi signal and uses its reflections to track moving humans. It can do so even if the humans are in closed rooms or hiding behind a wall.
As a Wi-Fi signal is transmitted at a wall, a portion of the signal penetrates through it, reflecting off any humans on the other side. However, only a tiny fraction of the signal makes it through to the other room, with the rest being reflected by the wall, or by other objects. “So we had to come up with a technology that could cancel out all these other reflections, and keep only those from the moving human body,” Katabi says.
I am sorry. I think this is absolutely invasive and unacceptable.
“Whenever you find yourself on the side of the majority, it is time to pause and reflect.”
