Handle
A handle is a part of, or attachment to, an object that allows it to be grasped and manipulated by hand. The design of each type of handle involves substantial ergonomic issues, even where these are dealt with intuitively or by following tradition. Handles for tools are an important part of their function, enabling the user to exploit the tools to maximum effect. Package handles allow for convenient carrying of packages. General design criteria The three nearly universal requirements of are: # Sufficient strength to support the object, or to otherwise transmit the force involved in the task the handle serves. # Sufficient length to permit the hand or hands gripping it to reliably exert that force. # Sufficiently small circumference to permit the hand or hands to surround it far enough to grip it as solidly as needed to exert that force. Specific needs Other requirements may apply to specific handles: * A sheath or coating on the handle that provides friction against th ...

Mortise Lock
A mortise lock (also spelled mortice lock in British English) is a lock that requires a pocket—the mortise—to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. The design is widely used in domestic properties of all vintages in Europe. History Mortise locks have been used as part of door hardware systems in the US since the second quarter of the eighteenth century. In these early forms, the mortise lock mechanism was combined with a pull to open the unlocked door. Eventually, pulls were replaced by knobs. Until the mid-nineteenth century, mortise locks were only used in the most formal rooms in the most expensive houses. Other rooms used box locks or rim locks; in contrast with embedded mor ...

Door
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate locking ...

Accessibility
Accessibility is the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers). Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone. Accessibility is not to be confused with usability, which is the extent to which a product (such as a device, service, or environment) can be used by specified users to achieve specified goals with effectiveness, efficiency, convenience, or satisfaction in a specified context of use. Accessibility is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The American Scholar
"The American Scholar" was a speech given by Ralph Waldo Emerson on August 31, 1837, to the Phi Beta Kappa Society of Harvard College at the First Parish in Cambridge in Cambridge, Massachusetts. He was invited to speak in recognition of his groundbreaking work ''Nature'', published a year earlier, in which he established a new way for America's fledgling society to regard the world. Sixty years after declaring independence, American culture was still heavily influenced by Europe, and Emerson, for possibly the first time in the country's history, provided a visionary philosophical framework for escaping "from under its iron lids" and building a new, distinctly American cultural identity. Summary Emerson introduces Transcendentalist and Romantic views to explain an American scholar's relationship to nature. A few key points he makes include: * We are all fragments, "as the hand is divided into fingers", of a greater creature, which is mankind itself. * An individual may live i ...

Ralph Waldo Emerson
Ralph Waldo Emerson (May 25, 1803April 27, 1882), who went by his middle name Waldo, was an American essayist, lecturer, philosopher, abolitionist, and poet who led the transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and his ideology was disseminated through dozens of published essays and more than 1,500 public lectures across the United States. Emerson gradually moved away from the religious and social beliefs of his contemporaries, formulating and expressing the philosophy of transcendentalism in his 1836 essay "Nature". Following this work, he gave a speech entitled "The American Scholar" in 1837, which Oliver Wendell Holmes Sr. considered to be America's "intellectual Declaration of Independence."Richardson, p. 263. Emerson wrote most of his important essays as lectures first and then revised them for print. His first two collections of essays, '' Essays: Firs ...
