Book Description
Impact protection during a crash is one of the primary functions of a flight helmet. In order for the helmet to provide effective impact protection, the helmet must remain firmly secured on the head for the entire duration of the crash sequence. If the helmet is displaced on the head or comes off during the crash sequence, cranial exposure and subsequent head injury can occur. Previous research at USAARL has shown the retention assembly of the SPH-4 flight helmet often allows excessive helmet rotation or even helmet loss to occur during a crash. This report describes the construction and testing of a new SPH-4 retention assembly, the USAARL yoke harness, which will alleviate the helmet rotation/helmet loss problem. The load versus elongation under load and comfort of the USAARL yoke harness was compared to that of the currently used standard retention harness. The USAARL yoke harness was stronger, and stretched less under load than the standard retention harness. Comfort testing of the USAARL yoke harness showed the majority (72 percent) of those questioned preferred the USAARL yoke harness over the standard harness. Keywords: Impact protection, Helmet, Yoke harness, Retention harness, Retention assembly. (sdw).

Book Description
The incorporation of technology into aviation has been exponential. Advancements in microelectronics, stealth technology, engine design, and electronic sensors and displays have converted simple aircraft into formidable flying machines. In this book, recognised experts in aviation helmet-mounted displays (HMDs) summarise 25 years of knowledge and experience in the area of HMD visual, acoustic, and biodynamic performance, and user interface issues such as sizing, fitting, and emergency egress.

Book Description
From the Preface: This book marks the first 50 years of the U.S. Army Medical Research and Materiel Command (USAMRMC). It documents a chronology highlighting some of the Command's many contributions to ensuring that world-class medical technologies are available to our service men and women. Our organizations and programs have evolved to support the needs of the warfighter in training, pre-deployment operations, deployment to nonhostile and hostile operations, post-deployment recovery and reconstitution, and into retirement.
