Berkeley Models, Inc. was an American company that manufactured model-airplane kits that pioneered such firsts as the nation's first gas model plane kit, and which became one of the industry's leading companies. Founded in the Brooklyn borough of New York City, New York, and later based in West Hempstead, New York, it lasted from 1933 to 1962.
Counter-IED equipmentare created primarily for militaryand law enforcement. They are used for standoff detection of explosives and explosive precursor components and defeating the Improvised Explosive Devices(IEDs) devices themselves as part of a broader counter-terrorism, counter-insurgency, or law enforcement effort.
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. [ 1] Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate ...
Prism (optics) A familiar dispersive prism. An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base ...
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
An optical spectrometer ( spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. [ 1] The variable measured is most often the irradiance of the light but could also, for instance ...
The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin- turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which ...
A “deep fake” company in the gray market of airplane parts “While there have always been gray and black markets in aircraft parts, mostly purchased by questionable customers, this is a case ...
