11/1/2006 - Peer reviewed journal articlesNIOSH researchers studied laser safety in potentially flammable environments. Researchers measured threshold igniting powers as a function of beam diameter for butane and propane-air mixtures by laser-heating targets placed on optical fiber tips.
-
9/1/2006 - Peer reviewed journal articlesResearchers conducted experiments to estimate the mean and standard deviation of laser powers needed to ignite 6% methane-air atmospheres using single-mode optical fiber tips covered by two types of iron oxide mixed with a ceramic adhesive.

5/9/2019 - Training materialsAppendix B of the OMSHR advanced tutorial on wireless communication and electronic tracking covering basic equations.
-
7/13/2018 - Peer reviewed journal articlesA study investigating the influence of a steel mass on the magnetic field distribution of a proximity detection system.
-
11/22/2016 - Interagency agreementsAn interagency agreement to improve signal-to-noise in TTE receivers. The aim is to use existing transmitters that are not "intrinsically safe" to provide a reference signal from underground.
-
7/19/2016 - Contracts and cooperative agreementsA contract to enhance key features of the through-the-earth prototype previously developed to improve its usability, investigate design changes to comply with mine safety standards, ruggedize the hardware, and demonstrate performance at coal mine sites.
