Active Control Unveils Starfish Feature For ActiveMine Wireless Communications System
Toronto, Canada (SPX) May 12, 2008 Active Control Technology has announced a major enhancement of ActiveMine, the premier wireless communications and locating system for mines, that represents a breakthrough in underground mining communications. The new feature, called "Starfish," for the first time makes it possible for miners who become isolated due to an accident, explosion or other event to stay linked, even when they are distant from one another and cut off from the outside world. "We know of no other communication system marketed to the mining community which has this capability," said Steve Barrett, President and CEO, Active Control. "Starfish demonstrates our commitment to ensuring ActiveMine remains the benchmark for wireless mine communications and locating systems." Starfish technology has operated successfully for over a month in the underground coal mine in West Virginia referenced in ACT's press release of May 1, 2008. This installation marked the first commercial sale of the ActiveMine system.
How Starfish Works With Starfish, even if a node or series of nodes becomes isolated from the main network, voice communications will automatically be re-established within the isolated area. The analogy in nature is that of a starfish: If a starfish's arm is severed, a complete new starfish is naturally regenerated by the severed section. This capability is currently not possible with analog walkie-talkie radios used in leaky feeder systems. When these radios lose their network connection (for example, because of a damaged leaky feeder cable), they provide line-of-sight communications to other radios within a few hundred feet. Consequently, miners located across a larger area or isolated behind pillars would likely be unable to communicate with one another should a leaky feeder network fail.
Additional Starfish Benefits - By making it possible for miners to find one another and provide mutual assistance, Starfish is particularly valuable for search and rescue operations. - As soon as an ActiveMine node in an isolated area "sees" signal from the main network, communications to the surface will automatically resume. - With the advent of Starfish, ActiveMine wireless mesh networks can now be set up for communications without a "Head End," where communications system controls are typically located. All that is required are nodes. This is cost-effective for small mines that track underground personnel "by administration" only and do not require electronic tracking. - This capability also enables the deployment of temporary local networks that are ideal for shorter-term activities requiring high quality communication links. - Starfish-enabled local networks can be connected to satellite phones, making it possible for isolated locations such as prospecting camps to have a fully digital communications and data network linked to "the outside world".
ActiveMine - Operate on a 100 percent wireless Wi-Fi network backbone. - Be less susceptible to water and mechanical damage of all sorts, including rock fall. - Use open-standards technology. - Meet federal MINER Act requirements for wireless systems as established in MSHA policies. - Provide four-day intrinsically safe battery back-up and power supply. - Provide a wireless communications and data network above-ground, linked seamlessly to underground networks.

KVH Introduces New CNS-5000 GPS/IMU Continuous Navigation System
Middletown RI (SPX) May 12, 2008KVH Industries has introduced the CNS-5000, a self-contained navigation system that combines fiber optic gyro (FOG)-based inertial measurement technology from KVH with global positioning system (GPS) technology from NovAtel. This rugged navigation solution affordably provides the precise position and orientation of a host platform on a continuous basis, even during periods where GPS signals are blocked by natural or man-made obstructions or conditions. |
