Radar beacon. Racon signal as seen on a radar screen. This beacon receives using sidelobe suppression and transmits the letter "Q" in Morse code near Boston Harbor (Nahant) 17 January 1985. Radar beacon (short: racon) is – according to article 1.103 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1 ...
Radio navigation. Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. [1] [2] Like radiolocation, it is a type of radiodetermination . The basic principles are measurements from/to electric beacons, especially.
Global Medical Device Nomenclature ( GMDN) is a system of internationally agreed generic descriptors used to identify all medical device products. This nomenclature is a naming system for products which include those used for the diagnosis, prevention, monitoring, treatment or alleviation of disease or injury in humans.
Look-down/shoot-down radars have been enhanced with electronic programs that process the radar image and search for moving objects, which are detected by looking for Doppler shifts in the radar return. See moving target indication. The radar removes all stationary objects (e.g. the ground and buildings) from the display and shows only moving ...
Generic Product Identifier. The Generic Product Identifier ( GPI) is a 14-character hierarchical classification system created by Wolters Kluwer's Medi-Span that identifies drugs from their primary therapeutic use down to the unique interchangeable product regardless of manufacturer or package size. The code consists of seven subsets, each ...
The UIC identification marking for tractive stock is a standard for identifying train stock like locomotives that supply tractive force primarily in Europe. Since the beginning of 2007 locomotives or other traction units in Europe have been given a 12-digit number. Vehicle numbering is now governed by the Intergovernmental Organisation for ...
The second treats an accurate pyramidal beam through the pixel and along a complex path, but it only works for polyhedrical shapes. Cone tracing solves certain problems related to sampling and aliasing, which can plague conventional ray tracing. However, cone tracing creates a host of problems of its own. For example, just intersecting a cone ...
The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies.It is maintained by Jet Propulsion Laboratory (JPL) and NASA and provides data for all known asteroids and several comets, including orbital parameters and diagrams, physical diagrams, close approach details, radar astrometry, discovery circumstances, alternate designations and lists of publications ...
In Electrical Power Systems and Industrial Automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI/IEEE Standard C37.2 "Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations".
ISO 22324. ISO 22324:2022, Security and resilience — Emergency management — Guidelines for colour-coded alerts, is an international standard developed by ISO/TC 292 Security and resilience. This document provide guidelines for color codes to indicate severity of hazards in public warnings.
