Book Description
To determine motion fidelity requirements, a series of piloted simulations was performed. Several key results were found. First, lateral and vertical translational platform cues had significant effects on fidelity. Their presence improved performance and reduced pilot workload. Second, yaw and roll rotational platform cues were not as important as the translational platform cues. In particular, the yaw rotational motion platform cue did not appear at all useful in improving performance or reducing workload. Third, when the lateral translational platform cue was combined with visual yaw rotational cues, pilots believed the platform was rotating when it was not. Thus, simulator systems can be made more efficient by proper combination of platform and visual cues. Fourth, motion fidelity specifications were revised that now provide simulator users with a better prediction of motion fidelity based upon the frequency responses of their motion control laws. Fifth, vertical platform motion affected pilot estimates of steady-state altitude during altitude repositioning. Finally, the combined results led to a general method for configuring helicopter motion systems and for developing simulator tasks that more likely represent actual flight. The overall results can serve as a guide to future simulator designers and to today's operators.Schroeder, Jeffery AllynAmes Research CenterFLIGHT SIMULATION; HELICOPTERS; ESTIMATES; VERTICAL MOTION; VISUAL STIMULI; YAW; CONTROL THEORY; CUES; PREDICTIONS; ROTATION; STEADY STATE; WORKLOADS (PSYCHOPHYSIOLOGY)

Book Description
A number of simulation features have been incorporated into military flight simulators in the belief that they add to the realism and, therefore, increase the training value (e.g., G-suit and G-seat simulation, visual dimming to simulate Gs). Motion simulation has been in this category; however, transfer of training studies have generally yielded inconclusive answers or lack of positive training value of motion for both multi-engine and fighter/attack simulators. Few studies have addressed the contribution of motion simulation to the training of helicopter pilots. This is the second in a series of four studies designed to assess the training effectiveness of the Device 2F64C, SH-3 helicopter flight simulator. The overall program is concerned with evaluating the training effectiveness of the device in various configurations. The present study was concerned with: assessing the contribution of motion simulation to the training of helicopter fleet replacement pilots; assessing the engineering fidelity of the motion platform concurrent with the study to insure that it was performing to design specifications; and identifying variables that are predictive of training success in fleet replacement training environment.

Book Description
Patent laws are different in many countries, and inventors are sometimes at a loss to understand which basic requirements should be satisfied if an invention is to be granted a patent. This is particularly true for inventions implemented on a computer. While roughly a third of all applications (and granted patents) relate, in one way or another, to a computer, applications where the innovation mainly resides in software or in a business method are treated differently by the major patent offices in the US (USPTO), Japan (JPO), and Europe (EPO). The authors start with a thorough introduction into patent laws and practices, as well as in related intellectual property rights, which also explains the procedures at the USPTO, JPO and EPO and, in particular, the peculiarities in the treatment of applications centering on software or computers. Based on this theoretical description, next they present in a very structured way a huge set of case studies from different areas like business methods, databases, graphical user interfaces, digital rights management, and many more. Each set starts with a rather short description and claim of the "invention", then explains the arguments a legal examiner will probably have, and eventually refines the description step by step, until all the reservations are resolved. All of these case studies are based on real-world examples, and will thus give an inexperienced developer an idea about the required level of detail and description he will have to provide. Together, Closa, Gardiner, Giemsa and Machek have more than 70 years experience in the patent business. With their academic background in physics, electronic engineering, and computer science, they know about both the legal and the subject-based subtleties of computer-based inventions. With this book, they provide a guide to a patent examiner’s way of thinking in a clear and systematic manner, helping to prepare the first steps towards a successful patent application.

Book Description
THe NASA Ames Digital Image Generation (DIG) system was purchased from the Link division of Singer Inc. The system provides a simulated out-the-window, visual image for a larg-vertical-motion flight simulator. As originally designed, the DIG can support four visual channels, which represent four aircraft windows with a single pilot eyepoint. The visual system was originally designed to support flight simulations of high altitude, high speed, fixed-wing aircraft. A Helicopter Air Combat (HAC) simulation required modifications to the DIG real-time software to support two helicopters engaged in low speed, low altitude, air-to-air combat. These modications included a second eyepoint to provide an out-the-window visual image for the secod aircraft pilot, new moving-target occulating algorithms, an algorithm to test for the existence of a clear line of sight between the opposing helicopters, and the addition of moving rotors on the helicopters in the scene. These modifications to the NASA Ames vertical Motion Simulator (VMS) system allowed two aircraft to ge independently piloted on a single CGI data base.
