William C. Eddy
William Crawford Eddy (August 22, 1902 – September 15, 1989) was a Naval officer, submariner, engineer, television producer, educator, cartoonist, artist, inventor, entrepreneur, explorer and writer. Bill Eddy was born and raised in Saratoga Springs, New York, where his father was a successful businessman and four-term mayor. He completed high school at the New York Military Academy, then received an appointment to the United States Naval Academy. With minimal hearing capability, he passed the physical examination by "reading lips," then kept this deficiency hidden throughout his years at the academy and during his initial military service. Early career Upon graduating from the Naval Academy in 1926, Eddy's first assignment as an Ensign (rank), ensign was on the light cruiser . He was initially sent to Nicaragua to "fight the Banana Wars," then dispatched to China to protect American interests and "show the flag" along the Yangtze River. In 1928, Eddy requested and receive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WNBC
WNBC (channel 4) is a television station in New York City, serving as the flagship of the NBC network. It is owned and operated by the network's NBC Owned Television Stations division alongside Linden, New Jersey–licensed Telemundo station WNJU (channel 47). WNBC's studios and offices are co-located with NBC's corporate headquarters at 30 Rockefeller Plaza in Midtown Manhattan; WNJU's facilities in Fort Lee, New Jersey, also serve as WNBC's New Jersey news bureau. Through a channel sharing agreement with WNJU, the two stations transmit using WNJU's spectrum from an antenna atop One World Trade Center. WNBC holds the distinction as the oldest continuously operating commercial television station in the United States. History Experimental operations What is now WNBC traces its history to experimental station W2XBS, founded by the Radio Corporation of America (RCA, a co-founder of the National Broadcasting Company), in 1928, just two years after NBC was founded as the first nat ...

Naval Research Laboratory
The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research. As of 2016, NRL was a Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year. Research The Naval Research Laboratory conducts a wide variety of basic research and applied r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microwave
Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively. Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio-frequency engineering is the range between 1 and 100 GHz (wavelengths between 0.3 m and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations. The prefix ' in ''microwave'' is not meant to suggest a wavelength in the micrometer range. Rather, it indicates that microwaves are "small" (having shorter wavelengths), compared to the radio waves used prior to microwave te ...

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 ...

Electronics Training Program
The Electronics Training Program (ETP) was the name commonly used for an unusual, difficult, and selective training activity of the United States Navy during World War II. The ETP combined college-level classroom instruction with laboratories involving highly complex electronic systems that were classified secret, resulting in a level of training reported to have been the most intense and difficult ever given to enlisted servicemen. A highly regarded Naval officer noted that the ETP graduates were in the top three to five percent of the Navy's wartime personnel, officers as well as enlisted men. Background As America entered WW II, there was a crisis concerning the availability of men qualified to maintain the huge amount of complex electronic equipment being procured for the Navy's ships, aircraft, submarines, and shore stations. The Navy had over 200,000 personnel, but only a few hundred were radio technicians, most having obtained their qualification through self-study and on ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Bureau Of Navigation
The Bureau of Navigation, later the Bureau of Navigation and Steamboat Inspection and finally the Bureau of Marine Inspection and Navigation — not to be confused with the United States Navys Bureau of Navigation — was an agency of the United States Government established in 1884 to enforce laws relating to the construction, equipment, operation, inspection, safety, and documentation of merchant vessels. The bureau also investigated marine accidents and casualties; collected tonnage taxes and other navigation fees; and examined, certified, and licensed merchant mariners. When established, the Bureau of Navigation was a part of the United States Department of the Treasury. In 1903, the organization was transferred to the newly formed United States Department of Commerce and Labor. In 1913 that department was split into the United States Department of Commerce and the United States Department of Labor, and the bureau was assigned to the new Department of Commerce. In 1932 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

WBBM-TV
WBBM-TV (channel 2) is a television station in Chicago, Illinois, United States, airing programming from the CBS network. Owned and operated by the network's CBS News and Stations division, the station maintains studios on West Washington Street in the Loop district, and its transmitter is located atop the Willis Tower. History Early history (1940–1953) WBBM-TV traces its history to 1940 when Balaban and Katz, a subsidiary of Paramount Pictures, signed on experimental station W9XBK, the first all-electronic television facility in Chicago. Balaban and Katz was already well known for owning several movie theaters in the Chicago area. In order to establish the station, the company hired television pioneer William C. "Bill" Eddy away from RCA's experimental station W2XBS in New York City. When World War II began, Eddy used the W9XBK facilities as a prototype school for training Navy electronics technicians. While operating the Navy school, Eddy continued to lead W9XBK and wrote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
