Objective: This study was designed to evaluate the performance of a pelvic restraint cushion (PRC), a submarining countermeasure that deploys under the thighs when a crash is detected in order to block the forward motion of the pelvis.
Methods: Sled tests approximating low- and high-speed frontal impacts were conducted with 4 female postmortem human subjects (PMHS) restrained by a lap and shoulder belt in the right front passenger seat. The subjects were tested with and without a PRC.
Results: The PRC is effective in reducing forward motion of the PMHS pelvis and reduces the risk of injury due to lap belt loading in a high-speed frontal crash.
Conclusions: Although small sample size limits the utility of the study's findings, the results suggest that the PRC can limit pelvic forward motion and that pelvic injury due to PRC deployment is not likely. 相似文献
Our jurisprudence assigns duties to persons to keep children safe. Under negligence law, a breach of duty causing an accident means the breaching party can be liable for damages inflicted on the injured person. Legislatures are considering new laws that reduce the damages that activity providers will need to pay to injured participants. Under some statutes, injured persons are precluded from maintaining lawsuits. In other cases, injured plaintiffs have a more stringent burden of proving liability. While activity providers may use insurance to pay for accident damages, for some injuries we might hold injured persons responsible. Four suggestions are offered as mechanisms to reduce tort litigation. 相似文献
ABSTRACT: Electric generation facility water requirement will increase substantially in the future in the Western United States because new power plants are to be constructed at inland sites rather than on the coast. At the inland locations, power plants will have to compete with agriculture and public users for fresh water supplies, and will be constrained by environmental legislation to dispose of cooling waste water in lined evaporation ponds. The various options for power plant cooling are analyzed in respect to cost, water consumption, and environmental hazard, and also in respect to their compatibility with existing state and federal regulations. Several proposals for balancing the water requirements of various users in water-scarce areas are reviewed and criticized. 相似文献
