Univac 1830
The CP-823/U, Univac 1830, was the first digital airborne 30-bit computing system. It was engineered, built and tested as the A-NEW MOD3 prototype computer for the Lockheed P-3 Orion. In 1963, the US Navy Dept., Bureau of Weapons, Naval Air Development Center contracted Univac Defense Systems Division of Sperry-Rand to perform a study of the feasibility of a central digital avionics computer for the Navy’s Project A-NEW, the ASW (Anti-Submarine Warfare) development for the Lockheed P-3 Orion. The idea was to develop and build the first central digital computing system able to coordinate the many sensors, MPD ( Multipurpose Display) and tactical air command functions. The study, “Final Report on Avionics Unit Computer Study 10-21-63”, concluded that a miniature, modular, digital avionics computer could be engineered, built and tested using current developing technologies. After a meeting in January 1964 with representatives from Univac and the Naval Air Development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicon Chip
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tiny MOSFETs (metal–oxide–semiconductor field-effect transistors) integrate into a small chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones and other home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs such as modern computer proce ...

Microelectronic Circuitry
Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller. These devices are typically made from semiconductor materials. Many components of normal electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive. Digital integrated circuits (ICs) consist of billions of transistors, resistors, diodes, and capacitors. Analog circuits commonly contain resistors and capacitors as well. Inductors are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logic Control
Logic Control is a control surface originally designed by Emagic in cooperation with Mackie. History Logic Control was designed by Emagic as a dedicated control surface for their Logic digital audio workstation software. It was manufactured by Mackie, but distributed by Emagic. About 6 months later, Mackie introduced a physically identical product called "Mackie Control" which included support for most major DAW applications, but not Logic. The Emagic Logic Control was still available and would only work with Logic. Later, Mackie Control's firmware was revised to include compatibility with Logic, combining together Mackie Control, Logic Control and Human User Interface (HUI) into a single protocol. As a result, the name was changed to "Mackie Control Universal" (MCU). Out of the box, MCU included Lexan overlays with different button legends to support control of other DAWs such as Pro Tools and Cubase. Description Logic Control (and now MCU) allows control of almost all Logic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Processor
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other compon ...

Word Length
In computing, a word is the natural unit of data used by a particular processor design. A word is a fixed-sized datum handled as a unit by the instruction set or the hardware of the processor. The number of bits or digits in a word (the ''word size'', ''word width'', or ''word length'') is an important characteristic of any specific processor design or computer architecture. The size of a word is reflected in many aspects of a computer's structure and operation; the majority of the registers in a processor are usually word-sized and the largest datum that can be transferred to and from the working memory in a single operation is a word in many (not all) architectures. The largest possible address size, used to designate a location in memory, is typically a hardware word (here, "hardware word" means the full-sized natural word of the processor, as opposed to any other definition used). Documentation for older computers with fixed word size commonly states memory sizes in words ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logic Operation
In mathematics and mathematical logic, Boolean algebra is a branch of algebra. It differs from elementary algebra in two ways. First, the values of the variables are the truth values ''true'' and ''false'', usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers. Second, Boolean algebra uses logical operators such as conjunction (''and'') denoted as ∧, disjunction (''or'') denoted as ∨, and the negation (''not'') denoted as ¬. Elementary algebra, on the other hand, uses arithmetic operators such as addition, multiplication, subtraction and division. So Boolean algebra is a formal way of describing logical operations, in the same way that elementary algebra describes numerical operations. Boolean algebra was introduced by George Boole in his first book ''The Mathematical Analysis of Logic'' (1847), and set forth more fully in his '' An Investigation of the Laws of Thought'' (1854). According to Huntington, the term "Boolean algebra" wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Arithmetic
A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" (zero) and "1" (one). The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because of the simplicity of the language and the noise immunity in physical implementation. History The modern binary number system was studied in Europe in the 16th and 17th centuries by Thomas Harriot, Juan Caramuel y Lobkowitz, and Gottfried Leibniz. However, systems related to binary numbers have appeared earlier in multiple cultures including ancient Egypt, China, and India. Leibniz was specific ...

Electronic Computing
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johnsville, Pennsylvania
Warminster Township (also referred to as Warminster) is located in Bucks County, Pennsylvania, United States. It was formally established in 1711. The township is 13.7 miles north of Philadelphia and had a population of 32,682 according to the 2010 U.S. census. History The town was called Warminster Township as early as 1685, before its borders were formally established in 1711. It was originally part of Southampton Township, which was founded in 1682 by William Penn. Warminster was named after a small town in the county of Wiltshire, at the western extremity of Salisbury Plain, England. Warminster, Pennsylvania was mostly settled by English and Scotch-Irish colonists after William Penn received a grant of land in the area from King Charles, II. It was the site of the Battle of Crooked Billet during the Revolutionary War, which resulted in a resounding defeat for George Washington's colonial troops. Warminster's Craven Hall is included in the National Register of Historic Places ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Printed Circuit Board
A printed circuit board (PCB; also printed wiring board or PWB) is a medium used in Electrical engineering, electrical and electronic engineering to connect electronic components to one another in a controlled manner. It takes the form of a Lamination, laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper Lamination, laminated onto and/or between sheet layers of a Insulator (electricity), non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it. Another manufacturing process adds Via (electronics), vias: plated-through holes that allow interconnections between layers. ...
