Patrick J. Hanratty
Patrick J. Hanratty was an American computer scientist and businessperson, known as the "Father of CAD/CAM"—computer-aided design and computer-aided manufacturing. Up to 2013, he was president and CEO of Manufacturing and Consulting Services (MCS) of Scottsdale, Arizona, a company he founded. According to the University of California in 2012, industry analysts think that "70 percent of all 3-D mechanical CAD/CAM systems available today trace their roots back to Hanratty’s original code".Professor Wayne Carlson in his course at Ohio State University traces this statistic to the MCS website which is no longer available. Early career Hanratty earned a PhD from the University of California, Irvine. He worked for General Electric, where in 1957 he wrote Pronto, an early commercial numerical control programming language. Then he moved in 1961 to General Motors Research Laboratories where he helped to develop DAC, (Design Automated by Computer). Banking standard Around the mid-195 ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

Magnetic Ink Character Recognition
Magnetic ink character recognition code, known in short as MICR code, is a character recognition technology used mainly by the banking industry to streamline the processing and clearance of cheques and other documents. MICR encoding, called the ''MICR line'', is at the bottom of cheques and other vouchers and typically includes the document-type indicator, bank code, bank account number, cheque number, cheque amount (usually added after a cheque is presented for payment) and a control indicator. The format for the bank code and bank account number is country-specific. The technology allows MICR readers to scan and read the information directly into a data-collection device. Unlike barcode and similar technologies, MICR characters can be read easily by humans. MICR encoded documents can be processed much faster and more accurately than conventional OCR encoded documents.

1931 Births
Events January * January 2 – South Dakota native Ernest Lawrence invents the cyclotron, used to accelerate particles to study nuclear physics. * January 4 – German pilot Elly Beinhorn begins her flight to Africa. * January 22 – Sir Isaac Isaacs is sworn in as the first Australian-born Governor-General of Australia. * January 25 – Mohandas Gandhi is again released from imprisonment in India. * January 27 – Pierre Laval forms a government in France. February * February 4 – Soviet leader Joseph Stalin gives a speech calling for rapid industrialization, arguing that only strong industrialized countries will win wars, while "weak" nations are "beaten". Stalin states: "We are fifty or a hundred years behind the advanced countries. We must make good this distance in ten years. Either we do it, or they will crush us." The first five-year plan in the Soviet Union is intensified, for the industrialization and collectivization of agriculture. * February 10 †...

NX (Unigraphics)
NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/ CAE, which has been owned since 2007 by Siemens Digital Industries Software. In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX. It is used, among other tasks, for: * Design (parametric and direct solid/surface modelling) * Engineering analysis (static; dynamic; electro-magnetic; thermal, using the finite element method; and fluid, using the finite volume method). * Manufacturing finished design by using included machining modules. NX is a direct competitor to CATIA, Creo, Autodesk Inventor. History 1972: United Computing, Inc. releases UNIAPT, one of the world's first end-user CAM products. 1973: The company purchases the Automated Drafting and Machining (ADAM) software code from MCS in 1973. The code became a foundation for a product called UNI-GRAPHICS, later sold commercially as Unigraphic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McDonnell Douglas
McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor, formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced well-known commercial and military aircraft, such as the DC-10 airliner, the F-15 Eagle air superiority fighter, the MD-80 airliner, and the F/A-18 Hornet multirole fighter. The corporation's headquarters were at St. Louis Lambert International Airport, near St. Louis, Missouri; its subsidiary, McDonnell Douglas Technical Services Company (MDTSC), was based elsewhere in St. Louis County, Missouri. At its peak in mid-1990, McDonnell Douglas employed 132,500 people. By the end of 1992, employment had dropped to approximately 87,400. History Background The company was formed from the firms of James Smith McDonnell and Donald Wills Douglas in 1967.

Computervision
Computervision, Inc. (CV) was an early pioneer in Computer Aided Design and Manufacturing (CAD/CAM). Computervision was founded in 1969 by Marty Allen and Philippe Villers, and headquartered in Bedford, Massachusetts, United States. Its early products were built on a Data General Nova platform. Starting around 1975, Computervision built its own "CGP" (Computervision Graphics Processor) Nova-compatible 16-bit computers with added instructions optimized for graphics applications and using its own operating system known as Computervision Graphic Operating System (CGOS). In the 1980s, Computervision rewrote their code to operate on Unix-based platforms. Computervision was acquired by Prime Computer in 1988 for $434 million. Prime subsequently adopted the Computervision name. On December 12, 1998 Parametric Technology Corporation acquired Computervision. CADDS product history Computervision's first product, CADDS-1, was aimed at the printed circuit board layout and 2-D drafting ma ...

Temporal Process Language
In theoretical computer science, Temporal Process Language (TPL) is a process calculus which extends Robin Milner's CCS with the notion of ''multi-party synchronization'', which allows multiple process to synchronize on a global 'clock'. This clock measures time, though not concretely, but rather as an abstract signal which defines when the entire process can step onward. Informal definition TPL is a conservative extension of CCS, with the addition of a special action called σ representing the passage of time by a process - the ticking of an abstract clock. As in CCS, TPL features action prefix and it can be described as being ''patient'', that is to say a process a.P will idly accept the ticking of the clock, written as a.P \rightarrow^a a.P Key to the use of abstract time is the ''timeout'' operator, which presents two processes, one to behave as if the clock ticks, one to behave as if it can't, i.e. \lfloor E \rfloor (F) \rightarrow^\sigma F provided process E does no ...
