A satellite-based positioning system is being developed to determine the location of farm equipment while working in the field. A satellite receiver mounted in a moving tractor or combine calculates position coordinates based on signals received from a selection of satellites in the Department of Defense Global Positioning System (GPS). The position coordinates are retrieved from the receiver by a computer and combined in a common data base with additional information collected by the computer such as yield, soil fertility, soil moisture, temperature, implement draft, and fuel consumption. There are a number of possible applications for this system. One is the automation of position information and data collection for research purposes. Comparison of results between years can be easily made. Another application is the optimized and automated application of manure, fertilizers and chemicals. Profits can be increased and environmental damage minimized.

The design and employment of teleoperated heavy equipment for safe and efficient handling of hazardous material requires a thorough understanding of task characteristics and variables which can effect operator performance. This is particularly true when accurate end effector positioning is required, and where mistakes can result in life threatening events. This paper presents results of a Lockheed Martin Environmental Systems and Technologies Company Independent Research and Development study to determine the effects of 2-D vs 3-D visual displays on operator-system performance during a set of tasks associated with the operation of a 110,000 pound Caterpillar 235 Front Shovel. The research program is in support of Department of Energy, Department of Defense, Bureau of Mines, and Lockheed Martin commercial program objectives.

The case study is presented with emphasis on the impact value engineering has on top management and management personnel.

Many materials have emerged from the aerospace and defense industries that may have a significant impact on commercial vehicles in the future. Some of these new materials were investigated for their application on Class 8 trucks. The most promising materials were applied to prototype parts and installed on a test truck as part of a lightweight development program. Most of these materials have unique characteristics that require a more complex and rigorous design process than the equivalent design with a conventional material. The major obstacles to be overcome are the high cost of the raw material and the development of automated fabrication methods.

The 21st Century Truck Initiative represents the premier partnership between government (Departments of Defense, Army, Energy, Transportation and the Environmental Protection Agency) and the U.S. trucking and supporting industries in seeking to develop and demonstrate commercially viable advanced technologies for trucks in the 21st century. At the request of senior leadership within the U.S. Departments of Defense and the Army, the Tank-automotive and Armaments Command's (TACOM) National Automotive Center (NAC), located at TACOM's Tank-Automotive Research, Development & Engineering Center (TARDEC), spearheaded the creation of this government-industry partnership to pursue the necessary leap-ahead technologies. By teaming the research and development efforts of government and industry, the partnership will improve fuel efficiency, increase safety, reduce owning and operating costs, and reduce emissions, while maintaining or enhancing the performance of military and commercial trucks.

Introducing water in a diesel engine has been known to decrease peak combustion temperatures and decrease NOx emissions. This however, has been limited to stationary and marine applications due to the requirement of a separate water supply tank in addition to the fuel tank, thereby a two-tank system. Combustion of hydrocarbon fuels produce between 1.35 (Diesel) and 2.55 times (Natural Gas) their mass in water. Techniques for extracting this water from the exhaust flow of an engine have been pursued by the United States department of defense (DOD) for quite some time, as they can potentially reduce the burden of supply of drinking water to front line troops in theater. Such a technology could also be of value to engine manufacturers as it could enable water injection for performance, efficiency and emissions benefits without the drawbacks of a two-tank system.

This standard provides general, dimensional and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment.

This standard shall be utilized as a procurement document only to the extent as agreed upon by the manufacturer and user.

Over the years, the DARPA Challenges in the United States have galvanized interest in autonomous cars, making them a real possibility in the mind of the public, but autonomous and unmanned vehicles have been increasingly employed in many roles on land, in the water, and in the air. Military applications have received a great deal of attention, with weaponized unmanned aircraft (drones) being the most prominent. However, unmanned vehicles with varying degrees of autonomy already have many civilian applications. Some of these are quite familiar (such as the Roomba autonomous vacuum cleaner), while others remain largely out of the public eye (such as autonomous farm equipment). Additional applications and more capable vehicles are rapidly coming to the markets in the years ahead. This book examines a number of economically important areas in which unmanned and autonomous vehicles, also understood here as autonomous technologies, are already used or soon will be.
