DARPA to develop new unified mathematical language for military

DARPA is working to create a unified mathematical language for everything the military sees or hears:

The armed forces are overwhelmed by all the data its various sensors are sniffing out. They want a single data stream that combines drone video feeds, cell phone intercepts, and targeting radar. Darpa’s solution, found in the brand-new Mathematics of Sensing, Exploitation, and Execution program is to design an algorithm that teaches the sensors how to interpret the world — how to think, how to learn and what data, accordingly to collect.

Sensors “process their signals as if they were seeing the world anew at every instant,” Darpa laments in its call for algorithms. To put it in Philosophy 101 terms, existence is, to a sensor, what William James called a “blooming, buzzing confusion“: an unmediated series of events to be vacuumed up, leaving an analyst overloaded with unsorted data. Wouldn’t it be better if a sensor could be taught how to filter the world through a perceptual prism, anticipating what the analyst needs to know?

That’s the specific military application of MSEE. But to get there, Darpa takes a rather unconventional path. To get the “economy and efficiency that derives from an intrinsic, objective-driven unification of sensing and exploitation,” it wants to create an “intrinsically integrated” algorithm for the machines to interpret reality. “All proposed research must describe a unifying mathematical formalism that incorporates stochasticity fundamentally,” Darpa tells would-be designers.

Dean Kamen's "Luke Arm" prosthesis just about ready for clinical trials

IEEE Spectrum Online has a special report on the current state of prosthethic arm development, including the latest on Dean Kamen's "Luke Arm" which is being funded by DARPA. There's also an amazing video showing the arm in action.

Kamen's next-gen prosthetic arm

Scott Kirsner has penned an article for The Boston Globe about the latest work being done by DARPA's Dean Kamen to develop the next generation of prosthetic limbs. Excerpt:

When Kamen, one of America's best-known inventors, first spoke with officers at the Pentagon's Defense Advanced Research Projects Agency, they told him they were looking for a research and development group that could build a prototype of a new prosthetic arm. Kamen was expecting to hear a list of technical specifications, such as how much the arm would need to lift and how many moving joints it would require. Instead, Kamen says, the Pentagon officials told him they wanted to create an arm that could "pick up a raisin or a grape from a table, know the difference without looking at it, and be able to manipulate it into the person's mouth without breaking it or dropping it."

"Wow," Kamen thought, "that is pretty much beyond the capability of current engineering."

Several hundred US soldiers have returned from Iraq and Afghanistan missing an arm, and several dozen have lost both arms, according to Kamen. The numbers are tragic - yet too small to motivate some of the largest makers of medical devices. But Kamen says, "You don't say no to DARPA, and you don't say no to a challenge that can be that much of a life-changer for people who need it."
