The Defense Advanced Research Project Agency is on the look-out for new ideas and risk-taking innovators.

In mid-April, DARPA plans to officially request executive summaries, white papers and research proposals for new defense systems, according to the agency. And in early May, DARPA’s Tactical Technology Office is holding pitch sessions called “Proposers’ Days.”

The agency is looking for emerging technologies for ground systems — combat vehicles and soldier and squad technologies, maritime and undersea systems, air systems and spacecraft technologies, among others.

Proposers’ Days allow “innovative risk-takers and DARPA to get together and learn from each other where the next huge leaps forward in technology could come from,” Tactical Technology Office Director Brad Tousley said in a statement.

BAE Systems unveils picture-taking Google Glass app

Arlington-based defense contractor BAE Systems has created a mobile picture-taking app that can be used with Google Glass, the company announced last week.

The app, which works on smartphones, tablets, and Google Glass devices, lets users take photos and record a title and description using their voices. Photos are automatically location-tagged, time-stamped and uploaded onto BAE Systems’ geo-spatial data server, GXP Xplorer.

The company expects to release the app for Google Glass later this year; a version of the app is currently available for download on devices running iOS and Android operating systems.

How government uses wireless signals

The National Telecommunications and Information Administration launched a new Web site last week intended to improve transparency about how federal agencies use wireless signals known as spectrum. shows which bands of spectrum — transmitting signals at a certain frequency — agencies are using between 225 MHz to 5 GHz. The information could give “non-federal stakeholders and technology developers a better sense of the potential opportunities and obstacles for accessing any particular band,” NTIA notes on the Web site.

Virginia high schools vie for cybersecurity cup

Eight teams from Virginia high schools competed in the Governor’s Cybersecurity Cup Challenge, a state-wide cyber defense competition held last week.

Students were asked to solve cybersecurity problems, such as securing operating systems or networks. Teams from Marshall Academy in Falls Church won the competition and also took second and third places.

Held at George Mason University, the event was organized by the Virginia Governor’s Office and the Air Force Association’s CyberPatriot National Youth Cyber Education Program. The competition, which included two practice rounds, two elimination rounds and in-person finals, started in January with 42 teams.

GAO denies Desbuild’s request to reconsider

The Government Accountability Office has denied a request filed by Hyattsville-based construction firm Desbuild to reconsider a Jan. 6 decision denying its protest of a contract won by Alexandria-based Biscayne Contractors, Hyattsville-based Meltech Corporation, District-based Montage Inc., and Purcellville-based TMG Construction Corporation.

The awards cover repair and renovation work at Federal Bureau of Investigation facilities, including the FBI’s headquarters in Washington, the FBI Academy in Quantico, and the Criminal Justice Information Services Complex in Clarksburg.

Desbuild also raised a new protest against the awards to Montage and TMG Construction Crop, arguing that there was a “substantial discrepancy” among the Desbuild’s pricing and these two businesses. The GAO denied this protest.
