Hand Dryer
A "hand dryer" is an electric machine which might make use of a heating element and an air blower to dry both the hands after hand washing. Since 1922, it is commonly used in public toilets around the world as a cost-effective alternative to paper towels. It may either operate with the gentle push of a button or automatically using a sensor. History The earliest hand dryer was patented on June 13, 1922 by R.B. Hibbard, D. J. Watrous and J.G. Bassett as a "Dryer Machine" for the Airdry Corporation of Groton New York. This machine was sold as a built in model or freestanding floor unit that consisted of an inverted blower (much like a handheld blow dryer) that was controlled by a floor pedal. Known as "Airdry The Electric Towel", these units were used in restrooms, barbershops and factories. Airdry Corporation moved to Chicago and San Francisco in 1924 to centralize their distribution. The hand dryer was later popularized in 1948 by George Clemens, who founded World Dryer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine To Dry Hands In Costco
A machine is a physical system that uses Power (physics), power to apply forces and control Motion, movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by Animal power, animals and Human power, people, by natural forces such as Wind power, wind and Water power, water, and by Chemical energy, chemical, Thermal energy, thermal, or electricity, electrical power, and include a system of mechanism (engineering), mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, ...

World Health Organization
The World Health Organization (WHO) is a list of specialized agencies of the United Nations, specialized agency of the United Nations which coordinates responses to international public health issues and emergencies. It is headquartered in Geneva, Switzerland, and has 6 regional offices and 150 field offices worldwide. Only sovereign states are eligible to join, and it is the largest intergovernmental health organization at the international level. The WHO's purpose is to achieve the highest possible level of health for all the world's people, defining health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." The main functions of the World Health Organization include promoting the control of epidemic and endemic diseases; providing and improving the teaching and training in public health, the medical treatment of disease, and related matters; and promoting the establishment of international standards for biologic ...

Personal Hygiene Products
Personal care products are consumer products which are applied on various external parts of the body such as skin, hair, nails, lips, external genital and anal areas, as well as teeth and mucous membrane of the oral cavity, in order to make them clean, protect them from harmful germs and keep them in good condition. They promote personal hygiene and overall health, well-being and appearance of those body parts. Toiletries form a narrower category of personal care products which are used for basic hygiene and cleanliness as a part of a daily routine. Cosmetic products, in contrast, are used for personal grooming and beautification (aesthetically enhance a person's appearance). Pharmaceutical products are not considered personal care products. Most of the personal care products are rinsed off immediately after use, such as shampoos, soaps, toothpastes, shower gels, etc. A few personal care products, however, are left on the applied surface such as moisturizing cream, sunscreen, et ...

Forest Conservation
Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as silviculture, forest protection, and forest regulation. This includes management for timber, aesthetics, recreation, urban values, water, wildlife, inland and nearshore fisheries, wood products, plant genetic resources, and other forest resource values. Management objectives can be for conservation, utilisation, or a mixture of the two. Techniques include timber extraction, planting and replanting of different species, building and maintenance of roads and pathways through forests, and preventing fire. Many tools like remote sensing, GIS and photogrammetry modelling have been developed to improve forest inventory and management planning. Scientific research plays a crucial role in helping forest management. For example, climate modeling, biodiversity research, carbon sequestration research, GIS applications ...

Towel
A towel () is a piece of absorption (chemistry), absorbent cloth or paper used for drying or wiping a surface. Towels draw moisture through direct contact. Bathing towels and hand towels are usually made of cotton, linen, bamboo and Microfiber, synthetic microfibers. In households, several types of towels are used, such as hand towels, bath towels, and Dishtowel, kitchen towels. Paper towels are provided in commercial or office Bathroom, bathrooms, via a dispenser, for users to dry their hands. They are also used for such duties such as wiping, cleaning, and drying. History According to Middle Ages archaeological studies, "... closely held personal items included the ever present knife and a towel." However, the invention of the towel is commonly associated with the city of Bursa, Turkey, in the 17th century. These Turkish towels began as a flat, woven piece of cotton or linen called a ''peshtamal'', often hand-embroidered. Long enough to wrap around the body, peshtamal were or ...

Paper Towel
A paper towel is an absorbent, disposable towel made from paper. In Commonwealth English, paper towels for kitchen use are also known as kitchen rolls, kitchen paper, or kitchen towels. For home use, paper towels are usually sold in a roll of perforated sheets, but some are sold in stacks of pre-cut and pre-folded layers for use in paper-towel dispensers. Unlike cloth towels, paper towels are disposable and intended to be used only once. Paper towels absorb water because they are loosely woven, which enables water to travel between the fibers, even against gravity ( capillary effect). They have similar purposes to conventional towels, such as drying hands, wiping windows and other surfaces, dusting, and cleaning up spills. Paper towel dispensers are commonly used in toilet facilities shared by many people (such as at schools or shopping malls), as they are often considered more hygienic than hot-air hand dryers or shared cloth towels.

Aural Diversity
Aural Diversity describes the plurality of the sense of hearing, encompassing the whole of human and animal nature and extending to machine listening. The Aural Diversity Infographic shows its scope, including: the many changes in so-called “normal” hearing that occur over a lifetime; the universal variations that affect everybody's hearing; the medically identifiable hearing conditions of roughly one sixth of the world's population; and an array of technologies that mediate hearing, such as hearing aids, prosthetics (e.g. cochlear implants, auditory brainstem implants, middle ear implants and bone conduction implants), and all kinds of hearable devices. An important feature of Aural Diversity is the recognition that it includes not only the many forms of hearing loss, but also an increased sensitivity to sound in conditions such as auditory processing disorder, auditory neuropathy spectrum disorder, tinnitus, hyperacusis, misophonia and various types of neurodivergence.

Distance
Distance is a numerical or occasionally qualitative measurement of how far apart objects, points, people, or ideas are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). The term is also frequently used metaphorically to mean a measurement of the amount of difference between two similar objects (such as statistical distance between probability distributions or edit distance between string (computer science), strings of text) or a degree of separation (as exemplified by distance (graph theory), distance between people in a social network). Most such notions of distance, both physical and metaphorical, are formalized in mathematics using the notion of a metric space. In the social sciences, distance can refer to a qualitative measurement of separation, such as social distance or psychological distance. Distances in physics and geometry The distance between physical locations can be defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a Power, root-power, and field quantities, power or root-power quantity on a logarithmic scale. Two signals whose level (logarithmic quantity), levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 101/20 (approximately ). The strict original usage above only expresses a relative change. However, the word decibel has since also been used for expressing an Absolute scale, absolute value that is relative to some fixed reference value, in which case the dB symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is "#Voltage, V" (e.g., "20 dBV"). As it originated from a need to express power ratios, two principal types of scaling of the decibel are used to provide consistency depending on whether the scaling refer ...

Dyson Airblade
Dyson Airblade is an electric hand dryer made by the Singapore-based company Dyson, found in public bathrooms around the world. It was introduced in the United Kingdom in 2006 and in the United States in late 2007. In 2013 the Airblade Tap was launched, which incorporates Airblade technology into a bathroom faucet enabling washing and drying in a single unit. Description Instead of using a wide jet of heated air, Dyson Airblade uses a thin layer of unheated air travelling at around as a squeegee to remove water, rather than using heat to evaporate the water. The Dyson Airblade is claimed by its manufacturer to dry hands in 10 seconds and to use less electricity than conventional hand dryers. The first commercially available high-speed, horizontal-wiping air dryer was the Mitsubishi Jet Towel, developed since 1991 and introduced in 1993. It has been available in the United States since 2005. There are several technical differences among electric hand dryers, such as airspeed, ...
