• Through-the-Earth Communication Antenna Feasibility Demonstration
  11/20/2015 - Contracts and cooperative agreements
  A contract to develop new antenna configurations to improve performance and utility of through-the-earth (TTE) communications systems once deployed in underground coal mines.
• Through-the-Earth (TTE) Communications: Range Reliability Improvements
  11/20/2015 - Contracts and cooperative agreements
  A contract to develop and test an enhanced magnetics-based communications waveform with increased ability to provide communications in the presence of ambient noise and interference in order to extend existing magnetics-based technologies.
• Underground Mine Diesel Particulate Monitor Network
  3/31/2015 - Contracts and cooperative agreements
  A contract to develop a monitor that can measure diesel particulate matter (DPM) in real time for at least a month and provide information on the mine-wide DPM concentrations to a central control station located on the surface.
• Smart Escape SCBA
  2/6/2015 - Contracts and cooperative agreements
  A contract to develop a “smart” self-contained open circuit breathing apparatus (SCBA) that protects against threat gasses and provides an extended duration of life-sustaining oxygen inhale stream by monitoring the surrounding atmosphere.
