Ray Dolby
Ray Milton Dolby (; January 18, 1933 – September 12, 2013) was an American engineer and inventor of the noise reduction system known as Dolby NR. He helped develop the video tape recorder while at Ampex and was the founder of Dolby Laboratories. Early life and education Dolby was born in Portland, Oregon, the son of Esther Eufemia (née Strand) and Earl Milton Dolby, an inventor. He attended Sequoia High School (class of 1951) in Redwood City, California. As a teenager in the decade following World War II, he held part-time and summer jobs at Ampex in Redwood City, working with their first audio tape recorder in 1949.

Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlie Ginsburg
Charles Paulson Ginsburg (July 27, 1920 – April 9, 1992) was an American engineer and the leader of a research team at Ampex which developed one of the first practical videotape recorders. Biography Ginsburg was born on July 27, 1920 in San Francisco, California. At the age of two, he was diagnosed with type 1 diabetes. He attended Lowell High School in San Francisco. Ginsburg earned a bachelor's degree from San Jose State University in 1948. He worked as an engineer at AM-radio station KQW (now KCBS). He joined Ampex in 1951, and remained there until his retirement in 1986, holding the title Vice President of Advanced Technology. The engineering team that helped create the videotape recorder while working for Ampex under his direction in early 1956 were Charles Andersen, Ray Dolby, Shelby Henderson, Fred Pfost, and Alex Maxey. Ginsburg was elected a member of the National Academy of Engineering in 1973, being cited for invention and pioneering development of video magneti ...

American Heritage Of Invention & Technology
''Invention & Technology Magazine'' (formerly known as ''American Heritage of Invention & Technology'') is a quarterly magazine dedicated to the history of technology. It was launched with sponsorship from General Motors in the summer of 1985 as a spinoff of ''American Heritage'' magazine. Later, the magazine had a partnership with the National Inventors Hall of Fame. “Our subject matter is actually nothing less than the making of the world we live in, and the stories of all the extraordinary people who made it,” wrote Frederick Allen, the Founding Editor, in 1985. He noted that the field of the history of technology is relatively new. "Up to now there has been no general magazine of wide circulation reporting on it. A gap exists between the findings of the scholars and the educated public," he wrote. There were three issues of the magazine a year until 1992, when it became quarterly. Following the Summer 2007 issue (volume 23, number 1), publication was suspended (along with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sound Recording And Reproduction
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to ...
