The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
An example of center to center communications is two traffic management centers that exchange real-time information about the inventory and status of traffic control devices. This allows each center system to know what timing plan, for example, the other center system is running to allow traffic signal coordination across center geographic ...
When information is exchanged between superior and subordinate, it is known as vertical two-way communication. On the other hand, when communication takes place between persons holding the same rank or position, it is called horizontal two-way communication. Two-way communication is represented in the following diagrams: [3]
Two-way communication systems have primarily been limited to lower-information-capacity applications, such as audio, facsimile, or radioteletype. For the most part, higher-capacity systems, such as two-way video communications or terrestrial microwave telephone and data trunks, have been limited and confined to UHF or microwave and to point ...
Iridium Communications satellite phones use frequencies between 1616 and 1626.5 MHz [4] to communicate with the satellites. Iridium Communications 2-way messaging service Snapdragon Satellite will utilize frequencies in the L Band as well. Inmarsat and Ligado Networks (formerly LightSquared) terminals use frequencies between 1525 and 1646.5 MHz.
VHF/UHF/SATCOM two-way, multi-mode voice and data radio communication system: E-8 Joint STARS: Rockwell Collins: AN/ARC-231: Skyfire VHF/UHF/SATCOM two-way, multi-mode voice and data radio communication system: BAE Systems: AN/ARC-232: Very High Frequency (VHF)/Ultra high frequency (UHF) radio communication system: Raytheon
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.
An emergency communication system (ECS) is any system (typically computer-based) that is organized for the primary purpose of supporting one-way and two-way communication of emergency information between both individuals and groups of individuals. These systems are commonly designed to convey information over multiple types of devices, from ...
