Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such ...

Formation Skydiving
Formation skydiving is a skydiving event where multiple skydivers attach themselves to one another by grabbing each other's limbs or by the use of "grippers" on their jumpsuit while free falling through the sky. The goal of this skydiving program is to build a formation of multiple divers arranged in a geometric pattern. Sub-categories Formation skydiving can be further divided into several sub-categories, so named for the number of members in a team: *4-way sequential *4-way vertical sequential (VFS, Vertical Formation Skydiving) *8-way sequential *16-way sequential *10-way speed *Large formations (Big-ways) Competitive format A competition in 4-way formation skydiving (FS-4) takes place like this: There are two kinds of formations, called randoms and blocks. The randoms are singular formations with full separation of all grips both before and after building the formation. The blocks are double formations with a special designated movement pattern in between, called an int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symmetric Multiprocessing
Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes. Most multiprocessor systems today use an SMP architecture. In the case of multi-core processors, the SMP architecture applies to the cores, treating them as separate processors. Professor John D. Kubiatowicz considers traditionally SMP systems to contain processors without caches. Culler and Pal-Singh in their 1998 book "Parallel Computer Architecture: A Hardware/Software Approach" mention: "The term SMP is widely used but causes a bit of confusion. ..The more precise description of what is intended by SMP is a shared memory multiprocessor where the cost of accessing a memory location ...

Fourway Athletics
Metro Gallery Football Club () is a Hong Kong football club which currently competes in the Hong Kong First Division. History The team began as Fourway Athletics (), it joined Hong Kong First Division in 2008–09 season as a competition member (, members who pay a specific amount of money and sponsor a domestic cup of Hong Kong to the Hong Kong Football Association, to join the Hong Kong First Division League) of the Hong Kong Football Association. In 2009–10 season, Fourway merged with Rangers in the Hong Kong Second Division and was renamed as Fourway Rangers () for the new season. In 2011–12 season, the team was renamed Biu Chun Rangers in deference to club sponsor ''Biu Chun Watches''. In 2012–13 season, the team was renamed as Yokohama FC Hong Kong as J. League Division 2 team Yokohama F.C. purchased the Hong Kong Football Association membership of the team. In the 2013–14 season, Yokohama FC Hong Kong moved their home ground from Siu Sai Wan Sports Gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-slide
A four-slide, also known as a multislide, multi-slide, or four-way, is a metalworking machine tool used in the high-volume manufacture of small stamped components from bar or wire stock. The press is most simply described as a horizontal stamping press that uses cams to control tools.. The machine is used for progressive or transfer stamping operations.. Design A four-slide is quite different from most other presses. The key of the machine is its moving slides that have tools attached, which strike the workpiece together or in sequence to form it. These slides are driven by four shafts that outline the machine. The shafts are connected by bevel gears so that one shaft is driven by an electric motor, and then that shaft's motion drives the other three shafts. Each shaft then has cams which drive the slides, usually of a split-type. This shafting arrangement allows the workpiece to be worked for four sides, which makes this machine extremely versatile. A hole near the center of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiway Switching
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location. A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room. In contrast to a simple light switch, which is a single pole, single throw (SPST) switch, multiway switching uses switches with one or more additional contacts and two or more wires are run between the switches. When the load is controlled from only two points, single pole, double throw (SPDT) switches are used. Double pole, double throw (DPDT) switches allow control from three or more locations. In alternative designs, low-voltage relay or electronic controls can be used to switch electrical loads, sometimes without the extra power wires. Three-way and four-way switches The controlled load is often a lamp, but multiway switching is used to control other electrical loads ...
