Pads
Pads (also called leg guards) are a type of protective equipment used in a number of sports and serve to protect the legs from the impact of a hard ball, puck, or other object of play travelling at high speed which could otherwise cause injuries to the lower legs. These are used by batters in the sport of cricket, catchers in the sports of baseball and fastpitch softball, and by goaltenders in sports such as ice hockey, ringette, bandy, rinkball, field hockey, rink hockey and box lacrosse. Cricket In cricket, pads fall into two types, batting pads and wicket-keeper's pads. In Test and first-class cricket, the pads are white (to match the rest of the player's whites), while in limited overs cricket they may be coloured. Batting Cricket pads first appeared in the mid-18th century in England. They were developed to protect the lower part of the legs from the hard leather ball that was used to bowl deliveries in the game. This was in response to the gradual evolution from underar ...

ThinkPad
ThinkPad is a line of business-oriented laptop computers and tablet computers, tablets designed, developed and marketed by Lenovo, and formerly by IBM until 2005, when IBM's Personal computer, PC business was acquired by Lenovo. ThinkPads have a distinct black, boxy design language, inspired by a Japanese ''bento'' lunchbox, which originated in 1990 and is still used in some models. Most models also feature a red-colored trackpoint on the keyboard, which has become an iconic and distinctive design characteristic associated with the ThinkPad line. The ThinkPad line was first developed at the IBM Yamato Facility in Japan, and the first ThinkPads were released in October 1992. It has seen significant success in the business market. ThinkPad laptops have been used in outer space and for many years were the only laptops certified for use on the International Space Station. ThinkPads have also for several years been one of the preferred laptops used by the United Nations. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego Padres
The San Diego Padres are an American professional baseball team based in San Diego. The Padres compete in Major League Baseball (MLB) as a member club of the National League (NL) West division. Founded in 1969, the club has won two NL pennants—in 1984 and 1998, losing in the World Series both years. As of 2022, they have had 16 winning seasons in franchise history. The Padres are one of two Major League Baseball teams (the other being the Los Angeles Angels) in California to originate from the state; the Athletics were originally from Philadelphia (and moved to the state from Kansas City), and the Dodgers and Giants are originally from two New York City boroughs—Brooklyn and Manhattan, respectively. As of 2022, the Padres are the only team in California not to have won a World Series. Following the relocation of the Chargers to Los Angeles in 2017, the Padres became the only franchise in the four major American professional sports leagues in the San Diego sports m ...

Notebook
A notebook (also known as a notepad, writing pad, drawing pad, or legal pad) is a book or stack of paper pages that are often ruled and used for purposes such as note-taking, journaling or other writing, drawing, or scrapbooking. History Early history During the fourteenth and fifteenth centuries, notebooks were often made by hand at home by drawing on them into gatherings that were then bound at a later date. The pages were blank and every notekeeper had to make ruled lines across the paper. Making and keeping notebooks was such an important information-management technique that children learned its skills in school. Legal pad According to a legend, Thomas W. Holley of Holyoke, Massachusetts, invented the legal pad around the year 1888 when he innovated the idea to collect all the sortings, various sorts of sub-standard paper scraps from various factories, and stitch them together in order to sell them as pads at an affordable and fair price. In about 1900, the latt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synthesiser
A synthesizer (also spelled synthesiser) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI. Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II, which was controlled with punch cards and used hundreds of vacuum tubes. The Moog synthesizer, developed by Robert Moog and first sold in 1964, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timbre
In music, timbre ( ), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or musical tone, tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments. It also enables listeners to distinguish different instruments in the same category (e.g., an oboe and a clarinet, both Woodwind instrument, woodwind instruments). In simple terms, timbre is what makes a particular musical instrument or human voice have a different sound from another, even when they play or sing the same note. For instance, it is the difference in sound between a guitar and a piano playing the same note at the same volume. Both instruments can sound equally tuned in relation to each other as they play the same note, and while playing at the same amplitude level each instrument will still sound distinctively with its own unique tone color. Experienced musicians are able to distinguish between diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodwind
Woodwind instruments are a family of musical instruments within the greater category of wind instruments. Common examples include flute, clarinet, oboe, bassoon, and saxophone. There are two main types of woodwind instruments: flutes and reed instruments (otherwise called reed pipes). The main distinction between these instruments and other wind instruments is the way in which they produce sound. All woodwinds produce sound by splitting the air blown into them on a sharp edge, such as a reed or a fipple. Despite the name, a woodwind may be made of any material, not just wood. Common examples include brass, silver, cane, as well as other metals such as gold and platinum. The saxophone, for example, though made of brass, is considered a woodwind because it requires a reed to produce sound. Occasionally, woodwinds are made of earthen materials, especially ocarinas. Flutes Flutes produce sound by directing a focused stream of air below the edge of a hole in a cylindrical tube. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roll Way
A roll way or running pad is the pad placed on a concrete slab or on the ties on the outside of the conventional track along both running rails of a rubber-tyred metro or along the unconventional track of a tram. The rubber-tyred wheels roll directly on the roll ways. * With a conventional track: ** The ones of the Montreal Metro are precast concrete on a concrete slab. ** The ones of the Paris Métro are H-steel on ties. ** The ones of the Mexico City Metro are H-steel. ** The ones of the Santiago Metro are precast concrete below ground and H-steel above ground. ** The ones of the Lausanne Metro Line M2 are H-steel. ** The ones of the Lyon Metro (lines A, B and D) are H-steel. * Without a conventional track: ** The ones of the Lille Metro are precast concrete. ** The ones of the Toulouse Metro are precast concrete. **The ones of the Sapporo Municipal Subway are flat steel with a central guide rail ** Busan Subway Line 4, runs directly on a concrete slab between guide bars * ...

Helicopter Landing Pad
A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing aircraft (VTOL), may be called ''vertiports.'' An example is Vertiport Chicago, which opened in 2015. Usage Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located remote from populated areas due to sounds, winds, space and cost constraints. However, some skyscrapers maintain a helipad on their roofs in order to accommodate air taxi services. Some basic helipads are built on top of highrise buildings for evacuation in case of a major fire outbreak. Major police departments may use a d ...

Launch Pad
A launch pad is an above-ground facility from which a rocket-powered missile or space vehicle is vertically launched. The term ''launch pad'' can be used to describe just the central launch platform (mobile launcher platform), or the entire complex (launch complex). The entire complex will include a ''launch mount'' or ''launch platform'' to physically support the vehicle, a service structure with umbilicals, and the infrastructure required to provide propellants, cryogenic fluids, electrical power, communications, telemetry, rocket assembly, payload processing, storage facilities for propellants and gases, equipment, access roads, and drainage. Most launch pads include fixed service structures to provide one or more access platforms to assemble, inspect, and maintain the vehicle and to allow access to the spacecraft, including the loading of crew. The pad may contain a flame deflection structure to prevent the intense heat of the rocket exhaust from damaging the vehicle or p ...

Brake Pad
Brake pads are a component of disc brakes used in automotive and other applications. Brake pads are composed of steel backing plates with friction material bound to the surface that faces the disc brake rotors. Function Brake pads convert the kinetic energy of a vehicle to thermal energy through friction. Two brake pads are contained in the brake with their friction surfaces facing the rotor. When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together onto the spinning rotor to slow and stop the vehicle. When a brake pad heats up due to contact with the rotor, it transfers small amounts of its friction material onto the disc, leaving a dull grey coating on it. The brake pad and disc (now both having the friction material), then "stick" to each other, providing the friction that stops the vehicle. In disc brakes, there are usually two brake pads per disc rotor, they both function together. These are held in place and actuated by a caliper affixe ...
