The on-board train protection device, the first device designed by Konkan Railway with their technical partner Kernex Microsystems (I) Ltd, was installed throughout the Indian Railway network. A new ACD Version-II, now called the Train Collision Avoidance System (TCAS), is under development by The Research Designs and Standards Organisation (RDSO).
Multifunction Advanced Data Link (MADL) is a fast switching narrow directional communications data link between stealth aircraft. [1] It began as a method to coordinate between F-35 (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capability to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems.
