Wheelchair
A wheelchair is a mobilized form of chair using 2 or more wheels, a footrest and armrest usually cushioned. It is used when walking is difficult or impossible to do due to Disease, illnesses, injury, Disability, disabilities, or age related health conditions. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand (self-propelled), by an attendant pushing from the rear using the handle(s), or by an attendant pushing from the side use a handle attachment. History The earliest records of wheeled furniture are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Man In Wheelchair With AFO Braces And Crutches
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome, X chromosome from the mother and a Y chromosome, Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, Prostate, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a ''transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caster
A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment. High capacity, heavy duty casters are used in many industrial applications, such as platform trucks, carts, assemblies, and tow lines in plants. Types Casters may be fixed to roll along a straight line path, or mounted on a pivot or pintle such that the wheel will automatically align itself to the direction of travel. Rigid casters A basic, rigid caster consists of a wheel mounted to a stationary fork. The orientation of the fork, which is fixed relative to the vehicle, is determined when the caster is mounted to the vehicle. An example of this is the wheels found at the rear of a shopping cart in North America. Rigid casters tend to restrict vehicle motion so that the vehicl ...

Center Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a di ...

Titanium
Titanium is a chemical element with the Symbol (chemistry), symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Kingdom of Great Britain, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titan (mythology), Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll process, Kroll and Hunter process, Hunter processes. The most common compound, titanium dioxide, is a popular photocatalysis, photocatalyst and is used in the manufacture of white pigments ...

Aluminium
Aluminium (aluminum in AmE, American and CanE, Canadian English) is a chemical element with the Symbol (chemistry), symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and Passivation (chemistry), forms a protective layer of Aluminium oxide, oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, Magnetism, non-magnetic and ductility, ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of Aluminum-26, 26Al is used in Radiometric dating, radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBOT
The iBOT is a powered wheelchair developed by Dean Kamen in a partnership between DEKA and Johnson & Johnson's Independence Technology division. History Development of the iBOT started in 1990 with the first working prototypes available in 1992. In late 1994, DEKA signed a deal with Johnson & Johnson to manufacture the unit, with Johnson & Johnson paying for all subsequent R&D with DEKA receiving a smaller royalty fee than they normally would in return for their retaining rights to all non-medical applications of the technology. Much of the manufacturing work for what was then a very secretive "Project FRED" was done at an SCI (Now Sanmina SCI) plant in Lacy's Spring, Alabama near SCI's corporate headquarters in Huntsville, Alabama. SCI was partnered with Criticon (Johnson & Johnson medical devices) to do development and manufacturing. Development of the iBOT was conducted at DEKA in Manchester, NH. The iBOT was revealed to the public on Dateline NBC in a segment by John Hockenb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Everest And Jennings
Everest & Jennings was a manufacturer of mobility and adaptive equipment. Everest & Jennings was the first company to mass-produce wheelchairs. Origins Herbert A. Everest and Harry C. Jennings Sr. were friends, and both were engineers. Herbert Everest was also physically disabled after surviving a mining accident in 1918. Everest complained to Jennings about the bulk of chairs available in the early 1930s, and in 1933, the pair designed and built a lightweight, collapsible model in Jennings' garage. The design was patented in October 1937. The pair soon went into business to manufacture their improved design. In the 1940s, they supplied disabled veterans of World War II through government contracts that established the company as a recognized name in rehabilitation equipment. The Everest family sold its interest in the company in 1943, but Gerald Jennings, son of Harry Sr., was chief executive from 1952 until he retired in 1985. In 1956, the company was "the first to manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bath Chair
A bath chair—or Bath chair—was a rolling chaise or light carriage for one person with a folding hood, which could be open or closed. Used especially by disabled persons, it was mounted on three or four wheels and drawn or pushed by hand. It is so named from its origin in Bath, England. If required, the chair could also be mounted on four wheels and drawn by a horse, donkey or small pony with the usual turning arrangement. These animal-drawn versions were the forerunners of the invalid carriage. James Heath, of Bath, who flourished before the middle of the 18th century, was the inventor of the bath,chair. where bathing in the Roman Baths or visiting the nearby Pump Room was popular amongst sick visitors. Later versions were a type of wheelchair which is pushed by an attendant rather than pulled by an animal. In the 19th century they were often seen at spa resorts such as Buxton and Tunbridge Wells. Some versions incorporated a steering device that could be operated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
