Regular (APR / ATC / ATO / ATS) blade-type fuses, also known as standard, were developed in 1976 as ATO by Littelfuse [2] for low voltage use in motor vehicles. Bussmann makes the ATC [3] that also complies with the same ISO 8820-3 and SAE J1284 standards. OptiFuse, a newer entrant in the market, makes regular (APR / ATC / ATO) fuses that meet ...
Japanese-style ATC cab signalling indicator. Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger.
Fuse packages may include a rejection feature such as a pin, slot, or tab, which prevents interchange of otherwise similar appearing fuses. For example, fuse holders for North American class RK fuses have a pin that prevents installation of similar-appearing class H fuses, which have a much lower breaking capacity and a solid blade terminal ...
An air tasking order (ATO) is a means by which the Joint Forces Air Component Commander (JFACC) controls air forces within a joint operations environment. The ATO is a large document written in United States Message Text Format (USMTF) that lists air sorties for a fixed 24-hour period, with individual call signs, aircraft types, and mission types (e.g. close air support or air refueling).
Friendly surface/submarine-launched AShM (for example, Harpoon, Exocet, Otomat). Bullseye An established point from which the position of an object can be referenced; made by cardinal/range or digital format. Bump/Bump-up Start temporary increase of flight altitude to set the aircraft to a favorable glide path to the target on the attack run ...

CBTC is a signalling standard defined by the IEEE 1474 standard. [1] The original version was introduced in 1999 and updated in 2004. [1] The aim was to create consistency and standardisation between digital railway signalling systems that allow for an increase in train capacity through what the standard defines as high-resolution train location determination.

In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. [1] The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices.
