Multi-Drop Bus / Internal Communication Protocol (MDB/ICP) is the latest, US-European iteration of a multidrop bus computer networking protocol used within the vending machine industry, currently published by the American National Automatic Merchandising Association and supported by the European Vending Association and the European Vending Machine Manufacturers Association.
Primarily, Kavach works on the principle of continuous supervision of the movement authority and is designed to maintain train speed within the specified limits and can automatically apply brakes to slow down or to bring the train to a complete standstill, incase the Loco Pilots violates the speed restrictions or fails to act in time to prevent Signal Passed At Danger (SPAD); thereby reducing ...
Device communication may also refer to how the hardware devices in a message exchange system enable the message exchange. For example, when browsing the Internet, a number of different devices work in tandem to deliver the message through the internet traffic—routers, switches and network adapters, which on a hardware level send and receive ...
The KG-84A is primarily used for point-to-point encrypted communications via landline, microwave, and satellite systems. The KG-84C is an outgrowth of the U.S. Navy high frequency (HF) communications program and supports these needs. The KG-84A and KG-84C are devices that operate in simplex, half-duplex, or full-duplex modes. The KG-84C ...
Soldiers can send text, data, voice and video communications beyond their area of operations without worrying that the information will fall into the hands of enemy forces. Soldiers can extend the range of their network in such a manner that communications cannot be jammed, detected, or intercepted. The US Army identifies the SMART-T as the AN ...
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).
Examples of a US-made set, the CDS-501, were captured in Cuba and are thought to have seen use in Central and Eastern Europe.The device operated in the upper part of the VHF band and sent high speed bursts of encrypted data from an agent to a receiving station located within a Western diplomatic facility in a hostile country to avoid interception by the adversary signals intelligence service.
A tachyonic antitelephone is a hypothetical device in theoretical physics that could be used to send signals into one's own past. Albert Einstein in 1907 [1] [2] presented a thought experiment of how faster-than-light signals can lead to a paradox of causality, which was described by Einstein and Arnold Sommerfeld in 1910 as a means "to telegraph into the past".
