As wireless devices proliferate and the radio spectrum becomes ever more congested, all users have a common interest in radio technologies that can accommodate the largest number of users but still enable priority traffic to get through. The DARPA Spectrum Challenge—a competitive demonstration of robust wireless technologies—recently announced the selection of 15 of 18 semifinalists for $150,000 in prize money. DARPA plans to fill three remaining wildcard slots in August 2013 before the September 2013 semifinals at DARPA’s offices in Arlington, Va.

DARPA-funded researchers recently demonstrated the world’s smallest vacuum pumps. This breakthrough technology may create new national security applications for electronics and sensors that require a vacuum: highly sensitive gas analyzers that can detect chemical or biological attack, extremely accurate laser-cooled chip-scale atomic clocks and microscale vacuum tubes.

 

Since 2000, more than 2,000 servicemembers have suffered amputated limbs. DARPA’s breakthrough research with advanced prosthetic limbs controlled by brain interfaces is well documented, but such research is currently limited to quadriplegics; practical applications of brain interfaces for amputees are still in the future. In contrast, nerve and muscle interfaces allow amputees to control advanced prosthetics in the near term. Recent demonstrations may give Wounded Warriors hope that they can soon take advantage of these breakthroughs.

 

DARPA’s Adaptable Sensor System (ADAPT) program aims to transform how unattended sensors are developed for the military by using an original design manufacturer (ODM) process similar to that of the commercial smartphone industry. The goal is to develop low-cost, rapidly updatable intelligence, surveillance and reconnaissance (ISR) sensors in less than a year, a marked improvement to the current three-to-eight year development process.
