MagSafe (Mac)
MagSafe is a series of proprietary magnetically attached power connectors developed by Apple Inc. for Mac laptops. Apple also uses the MagSafe name for MagSafe Attach, a wireless power transfer and accessory-attachment feature for the iPhone. The MagSafe power connector was introduced on 10 January 2006, in conjunction with the MacBook Pro, the first Intel-based Mac laptop, at the Macworld Expo. A MagSafe connector is held in place magnetically so that if it is tugged (for example, by someone tripping over the cable), it will be pulled out of the port without damaging the connector or the port, and without pulling the computer off its surface. A thinner and wider version, called MagSafe 2, was introduced in 2012. It was discontinued across Apple's product lines between 2016 and 2019 and replaced with USB-C and USB Power Delivery charging. MagSafe returned to Mac laptops with the introduction of updated MacBook Pro models with MagSafe 3 in 2021. History The basic concep ...

Computer
A computer is a machine that can be Computer programming, programmed to automatically Execution (computing), carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as Computer program, ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the Computer hardware, hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots.

Deep Fryer
A deep fryer (or deep fat fryer), sometimes referred to by the French name friteuse, is a kitchen appliance used to cook foods by full immersion in hot oil—deep frying. The cooking oil (or fats) are typically between temperatures of . Long common in commercial kitchens, household models now available have become increasingly prevalent. Deep frying has become well known in the United States, from frying sticks of butter to Twinkies, but the method can be traced back to Roman times. Features Deep fryers generally have a basket to lower the food into the oil tank and raise it when the food has finished cooking. Fryer baskets purchased separately are not standardized and when selected, need to fit into the deep fryer. There are timers and alarms, automatic devices to raise and lower the basket into and out of the oil, ventilation systems to exhaust frying odors from the kitchen, an oil filtration system or chemical treatment to improve the re-usability of the same amount of o ...

An apple is a round, edible fruit produced by an apple tree (''Malus'' spp.). Fruit trees of the orchard or domestic apple (''Malus domestica''), the most widely grown in the genus, are cultivated worldwide. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found. Apples have been grown for thousands of years in Eurasia before they were introduced to North America by European colonists. Apples have cultural significance in many mythologies (including Norse and Greek) and religions (such as Christianity in Europe). Apples grown from seeds tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the s ...

EmPower (aircraft Power Adapter)
EmPower is a brand name that refers to three different power outlets available on commercial airlines: * 15-volt, 75-watt DC connector (now called EmPower Classic by the vendor) * 5-volt, 10-watt USB power-only jacks * 110-volt AC power jacks (some also have an EmPower USB jack) Original 15-volt EmPower connector 15-volt Direct current, DC connector type found on many commercial airlines designed to provide power to travelers' electronic devices. The system is limited to 75 watts.EmPower Product Descriptiowww.astronics.com Accessed 2011-01-16. The use of a special connector is to prevent laptops charging at altitude and ensure that only approved adapters can be used. Some airlines offer it only in business class or only in certain types of aircraft or flights. Travelers in the 2000s bought EmPower adapters, frequently from duty-free shops at airports, to run laptops and other electronic equipment without using battery power. Supporting airlines include: * Some Air France pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...
