11/22/2016 - Contracts and cooperative agreementsA contract to provide detection of ambient conditions in lesser traversed, remote areas of a mine by way of a repeater system with sensing modules capable of linking into the existing, hardened communications and tracking system.
-
7/19/2016 - Contracts and cooperative agreementsA contract to develop and test a Media Converter Device (MCD) that allows wireless handheld radios to communicate with leaky feeder communication systems. This will greatly improve voice quality and underground communications coverage in cross-cuts.

4/1/1994 - Conference papersTo address communicating while wearing an SCSR, two-way, FM radios were built in and improved mouthpieces were added to the SCSR to improve the ability to communicate. Prototypes we built and tested. Leaky feeder systems are also described.
-
11/1/1981 - Contract reports, Open File ReportsAdvanced communication and monitoring systems were developed and demonstrated in three underground mines representing different mining techniques, geographical areas, and material mined.
-
7/1/1980 - Conference papersA summary is presented of existing leaky feeder communications systems currently in operation in North America. Background information pertaining to previous use of leaky feeder technology is discussed along with the survey methodology.
