VESA Enhanced Video Connector
The VESA Enhanced Video Connector is a VESA standard intended to reduce the number of cables around a computer by incorporating video, audio, FireWire and USB into a single cable system. The intention of the system was to make the monitor the central point of connection. Although the specific idea did not find favour with computer manufacturers, it was evolved into the somewhat more popular VESA Plug and Display standard. A VESA EVC connector is capable of carrying analog video (VGA-based) output, video input (composite), FireWire, audio (analogue stereo), and USB signals. Pinout is somewhat similar to the newer VESA Plug and Display. It can be distinguished from a Plug and Display connector by the shell, which is shaped like an isosceles trapezoid similar to the shell of a D-subminiature instead of the "D"-shaped shell of a DVI Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1A EVC Connector
The Springfield Armory M1A is a semi-automatic rifle made by Springfield Armory, Inc., beginning in 1974, based on the M14 rifle, for the civilian and law enforcement markets in the United States. "M1A" is a proprietary name for Springfield Armory's M14-pattern rifle. Early M1A rifles were built with surplus G.I. parts until Springfield Armory, Inc. began manufacturing their own. Differences between the M1A and M14 The M14 was developed to take the place of 4 different weapons systems: the M1 Garand, M1 carbine, M3 submachine gun, and M1918 Browning Automatic Rifle (BAR). It was thought that in this manner the M14 could simplify the logistical requirements of the troops by limiting the types of ammunition and parts needed to be supplied. It proved to be an impossible task to replace all four as the cartridge was too powerful for the submachine gun role and the weapon was too light to serve as a light machine gun replacement for the BAR. The Springfield Armory M1A is, for the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VESA
VESA (), formally known as Video Electronics Standards Association, is an American technical standards organization for computer display standards. The organization was incorporated in California in July 1989To retrieve the information, search for Entity Number C1645094. and has its office in San Jose. It claims a membership of over 300 companies. In November 1988, NEC Home Electronics announced its creation of the association to develop and promote a Super VGA computer display standard as a successor to IBM's proprietary Video Graphics Array (VGA) display standard. Super VGA enabled graphics display resolutions up to 800×600 pixels, compared to VGA's maximum resolution of 640×480 pixels—a 56% increase. The organization has since issued several additional standards related to computer video displays. Widely used VESA standards include DisplayHDR, DisplayPort, and Flat Display Mounting Interface.

FireWire
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic. Apple called the interface FireWire. It is also known by the brand names i.LINK (Sony), and Lynx (Texas Instruments). The copper cable used in its most common implementation can be up to long. Power and data is carried over this cable, allowing devices with moderate power requirements to operate without a separate power supply. FireWire is also available in Cat 5 and optical fiber versions. The 1394 interface is comparable to USB. USB was developed subsequently and gained much greater market share. USB requires a host controller whereas IEEE 1394 is cooperatively managed by the connected devices. History and development FireWire is Apple's name for the IEEE 1394 High Speed Serial Bus. Its development was initiated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VESA Plug And Display
VESA Plug and Display (P&D) is a video connector for digital monitors, such as flat panel displays and video projectors, ratified by VESA. It was introduced around the same time as DFP, marketed as a replacement of VESA Enhanced Video Connector (EVC) and an extension of DVI. Unlike DVI, it never achieved widespread implementation. The P&D connector shares the pin layout of VESA EVC, but the pins assigned for carrying analogue audio and video in signals are reused to carry digital video signals. Signals A basic P&D line carries single-link TMDS digital video signal (max 160 MHz), and supports VESA Display Data Channel version 2. Analogue video signals, if supported, must be capable of carrying at least 150 MHz bandwidth. USB version is not specified, but if supported, it would have been intended for contemporary USB standards. The USB connector is intended for passing mouse movements from a projector's wireless remote into the computer's presentation software. FireW ...

Isosceles Trapezoid
In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of equal measure. Note that a non-rectangular parallelogram is not an isosceles trapezoid because of the second condition, or because it has no line of symmetry. In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram). The diagonals are also of equal length. The base angles of an isosceles trapezoid are equal in measure (there are in fact two pairs of equal base angles, where one base angle is the supplementary angle of a base angle at the other base). Special cases Rectangles and squares are usually considered to be special cases of isosceles trapezoids though s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-subminiature
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems. Description, nomenclature, and variants A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. D-sub connectors have gender: parts with pin contacts are called ''male connectors'' or ''plugs'', while those with socket contacts are called ''female connectors'' or ''sockets''. The socket's shield fits tightly inside the plug's shield. Panel mounted connectors usually have #4-40 UNC (as designated with the Unified Thread Standard) jackscrews that accept screws on the cable end connector cover that are used for locking the connectors together and offering mechanical strain relief, and ca ...

Digital Visual Interface
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of digital video content. This interface is designed to transmit uncompressed digital video and can be configured to support multiple modes such as DVI-A (analog only), DVI-D (digital only) or DVI-I (digital and analog). Featuring support for analog connections, the DVI specification is compatible with the VGA interface. This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD play ...
