Available in PDF, EPUB and Kindle. Book excerpt: There are problems with the compatibility of spectacles and certain helmet mounted electro-optical visual display systems. The incompatibility has been partially resolved with single vision contact lenses. However, these contact lenses have not helped senior aviators, who must wear bifocal glasses due to their presbyopia. The purpose of this study was to compare the performance of bifocal soft contact lenses with that of bifocal spectacle lenses to determine if contact lenses are an option for helping older aviators meet the visual requirements needed to fly military aircraft. Seventeen volunteer presbyopic aviators from Fort Rucker were fitted with five bifocal soft contact lens combinations and bifocal glasses. A four-phase investigation was conducted: a clinical phase involving the fitting of the bifocal contact lenses; a laboratory phase involving measurements of visual functions; a simulator phase involving measures of visual performance in simulated flight conditions; and an operational phase consisting of subjective responses regarding in-flight use of bifocal contact lenses. In general, vision in the best performing bifocal contact lenses typically was slightly reduced from vision in bifocal spectacles. The amount of the reduction, and whether it was clinically significant, depended on the refractive error of the subject (myopes generally performed better), the add group of the subject (low add group subjects performed better), and the type of bifocal contact lens. Aviators performed flight simulation maneuvers better in bifocal contact lenses than in bifocal glasses, and they evaluated their own ease of vision while performing aviation duties to be much easier in bifocal contact lenses than in bifocal glasses. In actual flight operations, each aviator preferred bifocal contact lenses over bifocal spectacles. Bifocal soft contact lenses are an acceptable.

Book excerpt: Given its characteristics and the complexity of its use and its environment, the helicopter is exposed to damage and a whole series of measures can be previewed to alientate this risk. The presentations concentrated on five main topics: 1. Crew training; 2. The different conditions of use; 3. The psycho-physiological component; 4. Survival equipment and methods; and 5. Accidents and their prevention. A careful reading of the papers presented at the symposium will enable both specialists and decision-makers to make a summary assessment of the constraints of the missions on the one hand, and on the other, of the new methods of protection and training and the new technologies which will enable aircrew to carry out their missions in a safer environment. In addition, they will perhaps discover that helicopter operation can be optimised by a series of different devices and above all by judicious matching of "type of helicopter-type of aircrew training-type of additional on-board equipment".

This book was released on 1991-02-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.

Download or read book Aeromedical Training for Flight Personnel written by Department of the Army and published by . This book was released on 2009-08-31 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is intended for use by all Army crewmembers in meeting requirements set forth in Army Regulation 95-1, Training Circular 1-210, and other appropriate aircrew training manuals. Lessons learned from previous military conflicts and recent contingency operations have caused changes in Army aviation doctrine. With the development of more sophisticated aircraft and weapons systems, Army crewmembers must be capable of operating these systems around the clock, in austere environments, and under adverse conditions. The hazards of stress and fatigue in combat operations and concept of operations will eventually take a toll in aircrew performance and could jeopardize mission accomplishment unless crewmembers are trained to recognize and understand these hazards. Proper training prepares crewmembers and prevents stress and fatigue from reducing mission effectiveness, thereby increasing their chances of survival. Training Circular 3-04.93 provides crewmembers with an understanding of the physiological responses that can occur in the aviation environment. It also describes the effects of the flight environment on individual mission accomplishment. In addition, this publication outlines essential aeromedical training requirements (in Chapter 1) that assist commanders and flight surgeons in conducting aeromedical education for Army crewmembers. Subject areas addressed are by no means all inclusive but are presented to assist crewmembers in increasing performance and efficiency. This publication applies to the Active Army, the Army National Guard/Army National Guard of the United States, and the United States Army Reserve unless otherwise stated.

This book was released on 2018-06-23 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the human aspects of wearable technologies and game design, which are often neglected. It shows how user centered practices can optimize wearable experience, thus improving user acceptance, satisfaction and engagement towards novel wearable gadgets. It describes both research and best practices in the applications of human factors and ergonomics to sensors, wearable technologies and game design innovations, as well as results obtained upon integration of the wearability principles identified by various researchers for aesthetics, affordance, comfort, contextual-awareness, customization, ease of use, ergonomy, intuitiveness, obtrusiveness, information overload, privacy, reliability, responsiveness, satisfaction, subtlety, user friendliness and wearability. The book is based on the AHFE 2018 Conference on Human Factors and Wearable Technologies and the AHFE 2018 Conference on Human Factors in Game Design and Virtual Environments , held on July 21–25, 2018 in Orlando, Florida, and addresses professionals, researchers, and students dealing with the human aspects of wearable, smart and/or interactive technologies and game design research.

Download or read book Using Medicine in Science Fiction written by H. G. Stratmann and published by Springer. This book was released on 2015-09-14 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a clearly written, entertaining and comprehensive source of medical information for both writers and readers of science fiction. Science fiction in print, in movies and on television all too often presents dubious or simply incorrect depictions of human biology and medical issues. This book explores the real science behind such topics as how our bodies adapt to being in space, the real-life feasibility of common plot elements such as suspended animation and medical nanotechnology, and future prospects for improving health, prolonging our lives, and enhancing our bodies through technology. Each chapter focuses on a single important science fiction-related subject, combining concise factual information with examples drawn from science fiction in all media. Chapters conclude with a “Bottom Line” section summarizing the most important points discussed in the chapter and giving science fiction writers practical advice on how to incorporate them into their own creations, including a list of references for further reading. The book will appeal to all readers interested in learning about the latest ideas on a variety of science fiction-related medical topics, and offers an invaluable reference source for writers seeking to increase the realism and readability of their works. Henry G. Stratmann, MD, FACC, FACP is a cardiologist with board certifications in internal medicine, cardiology, and nuclear cardiology.
