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 to match the team uniform. 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 gradua ...

Synthesiser
A synthesizer (also synthesiser or synth) 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 of a musical note, sound or tone. Timbre distinguishes sounds according to their source, such as choir voices and musical instruments. It also enables listeners to distinguish instruments in the same category (e.g., an oboe and a clarinet, both woodwinds). 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 distinctive with its own unique tone color. Musicians distinguish instruments based on their varied timbres, even instruments playing notes at the same pitch and volume ...

Woodwind Instrument
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 of other materials include brass, silver, cane, and 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 across the edge of a hole i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roll Way
__NOTOC__ 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 Métro 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 betw ...

Helicopter Landing Pad
A helipad is the landing area of a heliport, in use by helicopters, powered lift, and vertical lift aircraft to land on surface. 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 (VTOL) aircraft, 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 away from populated areas due to sounds, winds, space and cost constraints. Some skyscrapers have one on their roofs 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 depart ...

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 liquid-propellant rocket, 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 deflector, flame deflection structure to prevent the intense heat of the roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 affi ...

One-time Pad
The one-time pad (OTP) is an encryption technique that cannot be Cryptanalysis, cracked in cryptography. It requires the use of a single-use pre-shared key that is larger than or equal to the size of the message being sent. In this technique, a plaintext is paired with a random secret Key (cryptography), key (also referred to as a ''one-time pad''). Then, each bit or character of the plaintext is encrypted by combining it with the corresponding bit or character from the pad using Modular arithmetic, modular addition. The resulting ciphertext is impossible to decrypt or break if the following four conditions are met: # The key must be at least as long as the plaintext. # The key must be True random, truly random. # The key must never be reused in whole or in part. # The key must be kept completely secret by the communicating parties. These requirements make the OTP the only known encryption system that is mathematically proven to be unbreakable under the principles of informat ...

IBM WorkPad
IBM WorkPad was a line of portable devices, produced by Palm Inc. and branded by IBM. This line contained personal digital assistants (PDAs) and one subnotebook model (WorkPad Z50). Overview This line was released in 1997 and discontinued in 2002. After discontinuation of its self-branded line, IBM still offers the main Palm line on its site. This IBM-branded line of PDAs were rebranded PalmPilots, with only a few software improvements (easy sync for Lotus Notes, DB2 EveryPlace, and IBM Mobile Connect). Reception Early WorkPad PDAs were received positively, similar to parallel Palm models; but later this conservative business-oriented line lacked notability, and multimedia options of latest models were described as relatively poor. Models WorkPad Z50 - 1999, subnotebook/thin client, powered by Windows CE, equipped with an NEC MIPS processor and with an 8.2" screen. PDAs All WorkPad PDAs have a similar gray-scale screen (with better resolution and contrast for C series, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
