Five-Point Harness
A five-point harness is a form of seat belt that contains five straps that are mounted to the car frame. It has been engineered for an increase of safety in the occurrence of an automobile accident. As a result, this form of seat belt has been mandated in the race car competition of NASCAR. This was an invention made mandatory to have due to the high velocities involved in the sport. Along with the design of the seat belt, helmet straps have been designed to increase the safety of the driver. This invention has also been used to secure infants and young children in child safety seats. Structure The five-point harness is preferred as a safety mechanism for its high amount of safety compared to other designs. The five-point harness consists of five straps. Two are located at the shoulders, two at the hips, and one at the crotch that all come to connect to a buckle release mechanism. This way of buckling up holds the driver's body tight in the seat, which in turn protects the up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Momentum
In Newtonian mechanics, momentum (more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If is an object's mass and is its velocity (also a vector quantity), then the object's momentum is : \mathbf = m \mathbf. In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second. Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it. Momentum depends on the frame of reference, but in any inertial frame it is a ''conserved'' quantity, meaning that if a closed system is not affected by external forces, its total linear momentum does not change. Momentum is also conserved in special relativity (with a modified formula) and, in a modified form, in electrodynamics, quantum mechanics, ...

National Child Passenger Safety Board
The National Child Passenger Safety Board, managed by the National Safety Council, maintains the quality and integrity of the National Child Passenger Safety Certification Training Program in the United States. The program is used to train and certify child passenger safety technicians and instructors in order to assist caregivers in safe transportation of children. Three of the most common issues that put children at risk: improperly used or installed safety seats, hot cars, and teen drivers. The Board is not limited to keeping kids safe in cars in the U.S. The work of Dr. Marilyn J. Bull to help shape automobile safety law in Chile was highlighted in March 2017 by AAP News. Background Traffic crashes are the leading cause of death in children in the United States. In fact, a child under 13 is involved in a crash every 33 seconds. Education and proper use of air bags, car seats, booster seats and seat belts helps save lives and can prevent injuries and deaths on our nation’s ...

Safety Harness
A safety harness is a form of protective equipment designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, braided wire cable, or synthetic webbing. It is attached securely to a stationary object directly by a locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached. An unrelated use with a materially different arresting mechanism is bungee jumping. Though they share certain similar attributes, a safety harness is not to be confused with a climbing harness used for mountaineering, rock climbing, and climbing gyms. Specialized harnesses for animal rescue or transfer, as from a dock to a vessel, are also made. Standards In North America, safety harne ...

Child Seat
A child safety seat, sometimes called an infant safety seat, child restraint system, child seat, baby seat, car seat, or a booster seat, is a seat designed specifically to protect children from injury or death during vehicle collisions. Most commonly these seats are purchased and installed by car owners, but car manufacturers may integrate them directly into their vehicle's design and generally are required to provide anchors and ensure seat belt compatibility. Many jurisdictions require children defined by age, weight, and/or height to use a government-approved child safety seat when riding in a vehicle. Child safety seats provide passive restraints and must be properly used to be effective. However, research indicates that many child safety restraints are often not installed or used properly. To tackle this negative trend, health officials and child safety experts produce child safety videos to teach proper car seat installation to parents and caregivers. In 1990, the ISO sta ...

Human Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the ...

Brain Damage
Neurotrauma, brain damage or brain injury (BI) is the destruction or degeneration of brain cells. Brain injuries occur due to a wide range of internal and external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage. A common category with the greatest number of injuries is traumatic brain injury (TBI) following physical trauma or head injury from an outside source, and the term acquired brain injury (ABI) is used in appropriate circles to differentiate brain injuries occurring after birth from injury, from a genetic disorder (GBI), or from a congenital disorder (CBI). Primary and secondary brain injuries identify the processes involved, while focal and diffuse brain injury describe the severity and localization. Recent research has demonstrated that neuroplasticity, which allows the brain to reorganize itself by forming new neural connections throughout life, provides for rearrangement of its workings. This allows the brain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ripstop
__NOTOC__ Ripstop fabrics are woven fabrics, often made of nylon, using a reinforcing technique that makes them more resistant to tearing and ripping. During weaving, stronger (and often thicker) reinforcement yarns are interwoven at regular intervals in a crosshatch pattern. The intervals are typically 5 to 8 millimeters (0.2 to 0.3 in). Thin and lightweight ripstop fabrics have a 2-dimensional structure due to the thicker yarns being interwoven in thinner cloth. Older lightweight ripstop fabrics display the thicker interlocking thread patterns in the material quite prominently, but more modern weaving techniques make the ripstop threads less obvious. A similar effect can be achieved by weaving two or three fine yarns together at smaller intervals.Fairchild's Dictionary of Textiles, 7th edition, pg. 474 Advantages of ripstop are the favourable strength-to-weight ratio and that small tears can not easily spread. Fibers used to make ripstop include cotton, silk, polyester, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevation
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while '' altitude'' or '' geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and '' depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Ca ...

Shock Absorber
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in air cylinders, the hot air is usually exhausted to the atmosphere. In other types of shock absorbers, such as electromagnetic types, the dissipated energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horizontal Plane
In astronomy, geography, and related sciences and contexts, a '' direction'' or '' plane'' passing by a given point is said to be vertical if it contains the local gravity direction at that point. Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system. Historical definition The word ''horizontal'' is derived from the Latin , which derives from the Greek , meaning 'separating' or 'marking a boundary'. The word ''vertical'' is derived from the late Latin ', which is from the same root as ''vertex'', meaning 'highest point' or more literally the 'turning point' such as in a whirlpool. Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book ''Perspective''.
