  2. Radar beacon - Wikipedia

    en.wikipedia.org/wiki/Radar_beacon

    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 ...

  3. Laser designator - Wikipedia

    en.wikipedia.org/wiki/Laser_designator

    A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively. When a target is marked by a designator, the beam is invisible ...

  4. Look-down/shoot-down - Wikipedia

    en.wikipedia.org/wiki/Look-down/shoot-down

    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 ...

  5. Adderall - Wikipedia

    en.wikipedia.org/wiki/Adderall

    Adderall is commonly used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy (a sleep disorder).. ADHD. Long-term amphetamine exposure at sufficiently high doses in some animal species is known to produce abnormal dopamine system development or nerve damage, but, in humans with ADHD, long-term use of pharmaceutical amphetamines at therapeutic doses appears to improve brain ...

  6. A new technique can detect newer 4G 'stingray' cell phone ...

    Newer cell site simulators, called “Hailstorm” devices, take advantage of similar flaws in 4G that let police snoop on newer phones and devices. Some phone apps claim they can detect stingrays ...

  7. Cone tracing - Wikipedia

    en.wikipedia.org/wiki/Cone_tracing

    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 ...

  8. Admiralty code - Wikipedia

    en.wikipedia.org/wiki/Admiralty_code

    Admiralty code. The Admiralty System or NATO System is a method for evaluating collected items of intelligence. [1] The system comprises a two-character notation assessing the reliability of the source and the assessed level of confidence on the information. The Admiralty system is used by NATO member nations and members of the Five Eyes community.

  9. UIC identification marking for tractive stock - Wikipedia

    en.wikipedia.org/wiki/UIC_identification_marking...

    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 ...

  10. Ray-tracing hardware - Wikipedia

    en.wikipedia.org/wiki/Ray-tracing_hardware

    The ray tracing algorithm solves the rendering problem in a different way. In each step, it finds all intersections of a ray with a set of relevant primitives of the scene. Both approaches have their own benefits and drawbacks. Rasterization can be performed using devices based on a stream computing model, one triangle at the time, and access ...

    en.wikipedia.org/wiki/Domain_Awareness_System

    The Domain Awareness System is the largest digital surveillance system in the world [2] as part of the Lower Manhattan Security Initiative in partnership between the New York Police Department and Microsoft to monitor New York City. [3] It allows the NYPD to track surveillance targets and gain detailed information about them, and is overseen by ...
