Harold Mertz
Harold J. "Bud" Mertz is considered to be the driving force in the creation of the Hybrid III crash test dummy, the standard dummy used today. Working with General Motors in the late 1960s, Mertz designed and built the dummy which is today the only recognized test device in both North America and Europe for restraint devices which protect against frontal collisions. Mertz earned his bachelor's degree in aeronautical engineering at Wayne State University, and took a course on fluid dynamics under the tutelage of Lawrence Patrick, who was at the time using himself as a guinea pig in investigating the effects of car crashes on humans. Patrick offered Mertz an opportunity to work as his research assistant, and Mertz accepted. Mertz went on to do his graduate studies at Wayne State, and worked with cadavers in crash testing studies too violent to use live volunteers. He completed his Ph.D. with a dissertation on whiplash Whiplash may refer to: * The long flexible part of a whip * Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid III
The Hybrid III is the standard crash test dummy for frontal crash tests as of the beginning of the 21st century. It was initially only a 50th percentile male (equal in height and weight to the average North American male at the time of its development). Hybrid III, the 50th percentile male dummy which made its first appearance in 1976, is the familiar crash test dummy. If he could stand upright, he would be 5' 9" tall and would have a mass of approximately 78 kg (172 lb). He occupies the driver's seat in all the Insurance Institute for Highway Safety (IIHS) 65 km/h (40 mph) offset frontal crash tests. Hybrid III has a "big brother" model, the 95th percentile Hybrid III, at 188 cm (6'2") and 100 kg (223 lb). The 'female' Hybrid III is a 5th percentile dummy that is based on the same male body shape as the others, at a diminutive 152 cm (5 ft) tall and 50 kg (110 lb). The two Hybrid III child dummies represent a 21 kg (47 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadaver
A cadaver or corpse is a dead human body that is used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and arts students. The term ''cadaver'' is used in courts of law (and, to a lesser extent, also by media outlets such as newspapers) to refer to a dead body, as well as by recovery teams searching for bodies in natural disasters. The word comes from the Latin word ''cadere'' ("to fall"). Related terms include ''cadaverous'' (resembling a cadaver) and ''cadaveric spasm'' (a muscle spasm causing a dead body to twitch or jerk). A cadaver graft (also called “postmortem graft”) is the grafting of tissue from a dead body onto a living human to repair a defect or disfigurement. Cadavers can be observed for their sta ...

General Motors Former Executives
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of ''captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late Middle Ages, late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It h ...

Harper Woods, Michigan
Harper Woods is a city in Wayne County in the U.S. state of Michigan. The city had a population of 15,492 at the 2020 census. Harper Woods is a northeastern suburb of Metro Detroit and shares its southern and western border with the city of Detroit. It was incorporated as a city from the last remaining portion of Gratiot Township in 1951. Etymology According to the city's website, Harper Woods was so named because it was then a wooded area and because its main thoroughfare was Harper Avenue (named for Walter Harper, founder of Harper Hospital in Detroit). History Harper Woods was incorporated as a city on February 19, 1951, from what was left of Gratiot Township. A charter commission was elected, a charter prepared and adopted, and a city council elected. The City of Harper Woods came into existence on October 29, 1951, when the charter took effect and the first city council was sworn in. The fledgling suburb faced the usual problems confronting new cities: schools, stree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whiplash (medicine)
Whiplash is a non-medical term describing a range of injuries to the neck caused by or related to a sudden distortion of the neck associated with extension, although the exact injury mechanisms remain unknown. The term "whiplash" is a colloquialism. "Cervical acceleration–deceleration" (CAD) describes the mechanism of the injury, while the term "whiplash associated disorders" (WAD) describes the subsequent injuries and symptoms. Whiplash is commonly associated with motor vehicle accidents, usually when the vehicle has been hit in the rear; however, the injury can be sustained in many other ways, including headbanging, bungee jumping and falls. It is one of the most frequently claimed injuries on vehicle insurance policies in certain countries; for example, in the United Kingdom 430,000 people made an insurance claim for whiplash in 2007, accounting for 14% of every driver's premium. In the United States, it is estimated that more than 65% of all bodily injury claims are whipl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically moder ...

Crash Test Dummy
A crash test dummy, or simply dummy, is a full-scale anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision. Prior to the development of crash test dummies, automobile companies tested using human cadavers, animals and live volunteers. Cadavers have been used to modify different parts of a car, such as the seatbelt. This type of testing may provide more realistic test results than using a dummy, but it raises ethical dilemmas because human cadavers and animals are not able to consent to research studies. Animal testing is not prevalent today. Computational models of the human b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
