The railroad industry is a good example of how VMI’s customized solutions work for a variety of applications. The railroads had a difficult time keeping track of all the railcars they manage. Remote inventory tracking was difficult and expensive until VMI provided a solution. Utilizing proprietary technology, VMI developed a system that provides a precise image of each car and collects automatic equipment identification data, even when traveling at speeds in excess of 70 mph. As is often the case, one good solution leads to another. The railroad system now provides information about the weight of the cars and maintenance problems that need attention. All information, both data and visual images, are compiled on the same record resulting in simplified operations and reduced costs.
A major communications company wanted to combine all its network management information in a highly comprehensive and reliable control environment. Working together with VMI they built a highly sophisticated video based control center, that allows network technicians to determine at a glance the status of their regional network.
Can you begin to see the possibilities for your operation? When it comes to managing information, critical to your operations or improving service to your customers, VMI can provide you with the solutions and applications that give you the edge over the competition. At VMI we listen to our customers, work with them to develop solutions that help accomplish their mission, and then deliver what we promise.
As a custom electronic systems integrator VMI has received numerous accolades over the past 4 decades including SBA's Prime Contractor of the Year Award and features on 60 Minutes, ABC News, Fox News, and CNN Espanol. VMI was recently featured in Special Operations Technology Magazine's article, "In the Mind Fight", and in The Year In Special Operations Magazine 2010-2011 edition.
PRESS RELEASES TO FOLLOW
Combat Support Military Personnel: U.S. Army Psychological Operations
"...There are two essential elements in Army PSYOP: the tactical team and the PDD (Product Develop Detachment). A tactical PSYOP team has 3-4 soldiers and is usually led by an E-5 (on occasion, an E-6) non-commissioned officer (NCO). The most apparent specialized equipment that a PSYOP team operates is the FOL (Family of Loudspeakers) The team carries both a large vehicle mounted speaker and a backpack loudspeaker system. Uses for this equipment are endless; a common mission needing loudspeaker support is a cordon and search..."
Giving Back: Haiti Restoration
Following the disastrous Earthquakes of 2010, the Haitian government alongside the U.N. and U.S. have banded together to begin rebuilding this ravaged country. VMI is offering its broadcast expertise to the project by way of loudspeaker systems to communicate critical information to areas of dangerous rubble, etc... Wireless cable stations are also being planned in order to further aid in the redevelopment of Haiti.
VMI was founded in 1976 by three military veterans, including Bob Cleveland. A former Lead Broadcast Engineer (USAF Staff Sergeant), Bob served AFRTS (Armed Forces Radio and Television service) throughout Southeast Asia during the 1968 Tet Offensive through the return of our POWs from Hanoi, Vietnam (1973). Working for 13th Air Force, SSG Cleveland was the principal engineer for AFRTS Networks in the Philippines, Thailand, Vietnam and Taiwan in network and station designs, upgrades and network development including microwave and satellite links. AFPN (American Forces Philippines Network) first introduced color television in 1971 as SSG Cleveland's task force of Army, Navy, Air Force and Marine engineers implemented Clark AB Base Commander's morale programs, and was one of the first broadcasters to began using satellites for live news and sports in 1968. Three members of his team later retired from service and joined Mr. Cleveland at VMI after their AFRTS team had provided all national & international press corps with Television and Radio coverage of Operation Homecoming (POWs returned from Hanoi) - an award winning effort and basis for Cleveland's MSM ( Meritorious Service Medal ).
Upon Cleveland's return to the U.S. and honorable discharge, he was hired by Kansas City based Alexander Electronics, a large broadcast & A/V equipment distributor/ integrator that overextended its growth. As the division head of its only profitable segment, Bob was asked by corporate bankers to liquidate, fulfill all payment obligations and to dissolve that corporation, which was accomplished within 18 months. In appreciation for this effort, the banker provided funds for a new entity named Video Masters, Inc. with Bob Cleveland, Paul Dark and Dave Rauth as founders/ principals.
VMI never lost touch with AFRTS, as Cleveland and many of the military/ AFRTS engineers worked together on unique challenges. Annual NAB meetings kept the Army abreast of VMI's unique ability to provide electronic solutions for difficult mission requirements. In 1981 the USA PSYOP Group identified their shortfalls in loudspeaker, radio and television broadcasting. AFRTS' Chief Engineer (TASA) sent them to VMI, as 'The Can-Do Company' for 'Anything'. From redesigning advanced media systems to lighter broadcasting transmitters/ stations and loudspeakers, VMI embraced these diverse requirements. Whether a direct requirement or FMS, a U.S. Base/Fort, or delivered to El Salvador, Philippines, Africa, the Middle East or Europe, VMI has produced broadcast systems expeditiously and cost effectively for the US Military, NATO, and various other DoD agencies and Allies around the world for three decades.
Prior to VMI, Cleveland and two former team members devoted weekends resolving a major issue with American railroads. Freight cars had to be slowed to 5 mph as they entered a yard, a clerk had to withstand environmental elements, standing beside the train as it entered, manually writing a list of each car ID. Then the train would stand-down until that list was typed into the terminal computer which then sent sorting/ rerouting instructions back to the conductor of each train, to the yard master, etc. Our U.S. Patent # 4,161,000 forever changed this archaic methodology. VMI became known throughout American railroads and by the late 80's was known throughout railroads worldwide for this video tracking system for railcar identification, which is still used at thousands of terminals. This VMI division was purchased by SAIC in 1993, who continues this service today.
