  Mine SafetyIn the event of trouble, knowing the precise location of the miners at risk can greatly assist rescuers. The more quickly the rescue team can reach miners at risk, the more likely the rescue operation will be successful. Currently, there is no technology capable of determining the precise location of underground miners. Continue… Location Aware Radiation MonitoringQ-Track worked with ORNL personnel to integrate a teledosimeter with Q-Track’s NFER® location system. A teledosimeter enables […]

Simulated Dosimetry for Realistic Radiation Worker Training Workers who understand how to use and interpret their personal radiation dosimeters can avoid health hazards and minimize costs for their employers. However, accurately simulating hazardous environments is a challenge. Q-Track answers that challenge with our Radiation Worker Training System. Using our patented technology, the system automatically and instantaneously correlates a worker’s actual location with a trainer-controlled simulated radiation environment. Our training dosimeter then displays the instantaneous and […]

Mine Safety

Introduction and Background  Recent tragedies at the Sago Mine, the Aracoma Alma Mine, and the Darby Mine have brought renewed attention to an old problem: situational awareness in mine emergencies. Improved communication is a partial, but not a complete, solution to the problem. Mine emergencies often involve dense smoke and dust that impair visibility and disorient even those familiar with the mine layout. Additionally, miners overcome by carbon monoxide cannot communicate useful information to potential rescuers. […]

  Waynesboro, Georgia May 18, 2009 –Southern Co. employs a unique type of active tag to track employees’ locations at its training center, as well as teach them how to avoid excessive radiation exposure. By Claire Swedberg Southern Co. has completed a pilot testing an RFID-based system to train employees in how to limit their exposure to radiation. The RFID system, provided by Q-Track, feeds a worker’s location data to software that then calculates the […]

Location Awareness for MOUT Training Huntsville, Alabama, June 4, 2008 Today, Q-Track demonstrated a system for tracking trainees in a Military Operations on Urban Terrain (MOUT) Training Range. The training range comprised several steel cargo containers modified with doors and windows. Q-Track’s NFER® real-time location system (RTLS) relied on four Locator-Receivers deployed around the perimeter of the training range. The system successfully tracked a couple of tagged individuals throughout the 25 x 25m (75 x […]
