Roll-up Door
A garage door is a large door to allow access to a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. The operating mechanism is usually spring-loaded or counterbalanced to offset the door's weight and reduce the human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss. Description A typical version of an overhead garage door used in the past would have been built as a one-piece panel. The panel was mounted on each side with an unequal parallelogram-style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers. The weight of the door may be or more but is balanced by either a torsion spring system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'' and many variations thereof. Its properties can be modified further by crosslinking or copolymerization. All forms are nontoxic as well as chemically resilient, contributing to polyethylene's popularity as a multi-use plastic. However, polyethylene's chemical resilience also makes it a long-lived and decomposition-resistant pollutant when disposed of improperly. Being a h ...

Electric Eye
An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam. The device does not provide an image; only the presence of light is detectable. Visible light may be used, but infrared radiation conceals the operation of the device and typically is used in modern systems. Originally, systems used lamps powered by direct current or the power line alternating current frequency, but modern photodetector systems use an infrared light-emitting diode modulated at a few kilohertz, which allows the detector to reject stray light and improves the range, sensitivity, and security of the device. Examples Highway vehicle counter * In the 1930s, an electric eye vehicle counter was introduced in the US using two IR lamps set apart so that only cars and pedestri ...

Do It Yourself
"Do it yourself" ("DIY") is the method of building, wikt:modification, modifying, or repairing things by oneself without the direct aid of professionals or certified experts. Academic research has described DIY as behaviors where "individuals use Raw material, raw and semi-raw materials and parts to produce, transform, or reconstruct material possessions, including those drawn from the natural environment (e.g., landscaping)". DIY behavior can be triggered by various motivations previously categorized as market economy, marketplace motivations (economic benefits, lack of product availability, lack of product quality, need for customization), and identity (social science), identity enhancement (Workmanship, craftsmanship, empowerment, community seeking, uniqueness). The term "do-it-yourself" has been associated with consumers since at least 1912 primarily in the domain of home improvement and maintenance activities. The phrase "do it yourself" had come into common usage (in stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Eye For Garage Door Opener
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

Cable Drum
A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables and wire products. Cable reels usually come in four different types, each with their own uses: wood, plywood, plastic and steel. Wooden drums Wooden drums come in three different varieties: steel-tyred for multiple use, export for sending abroad, and one-way drums for single trip use. Wooden drums can carry heavy loads and are constructed in resinous wood. Discarded wooden reels can often be obtained cheaply and are, owing to their shape, commonly used as furniture (usually coffee tables) for college students and others seeking inexpensive furnishings. Plywood drums/reels Plywood reels are used for transporting lighter loads and are a cheaper alternative to other types of drums, used extensively in the building industry and by commercial e ...

Garage (residential)
A residential garage ( , ) is a walled, roofed structure with a door for storage room, storing a vehicle or vehicles that may be part of or attached to a home ("attached garage"), or a separate outbuilding or shed ("detached garage"). Residential garages typically have space for one or two cars, although three-car garages are used. When a garage is attached to a house, the garage typically has an entry door into the house, called the ''person door'' or ''man door'', in contrast with the wider and taller door for vehicles, called the garage door, which can be opened to permit the entry and exit of a vehicle and then closed to secure the vehicle. A garage protects a vehicle from precipitation, and, if it is equipped with a locking garage door, it also protects the vehicle(s) from theft and vandalism. Most garages also serve multifunction duty as workshops for a variety of projects, including painting, woodworking, and assembly. Garages also may be used for other purposes as well, ...

Carriage House
A ''carriage house'', also called a ''remise'' or ''coach house'', is a term used in North America to describe an outbuilding that was originally built to house horse-drawn carriages and their related tack. Carriage houses were often two stories, with related staff quarters above. Current usages In modern usage, the term "carriage house" has taken on several additional, somewhat overlapping meanings: * Buildings that were originally true carriage houses that have been converted to other uses such as secondary suites, apartments, guest houses, automobile garages, offices, workshops, retail shops, bars, restaurants, or storage buildings. * Purpose-built secondary homes, also called accessory dwelling units or detached dwelling units, on the same lot as a primary residence. They have completely separate living areas and facilities, sometimes in the style of converted carriage houses. Some municipalities, such as Ottawa, Ontario, Canada, have introduced regulations per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeuomorphism
A skeuomorph (also spelled skiamorph, ) is a derivative object that retains ornamental design cues (attributes) from structures that were necessary in the original. Skeuomorphs are typically used to make something new feel familiar in an effort to speed understanding and acclimation. They employ elements that, while essential to the original object, serve no pragmatic purpose in the new system, except for identification. Examples include pottery embellished with imitation rivets reminiscent of similar pots made of metal and a software calendar that imitates the appearance of binding on a paper desk calendar. Definition and purpose The term ''skeuomorph'' is compounded from the Greek ''skeuos'' (σκεῦος), meaning "container or tool", and ''morphḗ'' (μορφή), meaning "shape". It has been applied to material objects since 1890. With the advent of graphical computer systems in the 1980s, skeuomorph is used to characterize the many "old fashioned" icons utilized in graphi ...
