In the Republic of Ireland, laws against metal detecting are very strict: it is illegal to use a detection device to search for archaeological objects anywhere within the State or its territorial seas without the prior written consent of the Minister for Culture, Heritage and the Gaeltacht, and it is illegal to promote the sale or use of ...
This list is incomplete; you can help by adding missing items. ( April 2019 ) This is a list of historically significant items found by metal detecting method, only excluding magnet fishing finds, since magnet fishing is usually considered a distinctively different and separate hobby from traditional metal detecting.
Speed sensors are machines used to detect the speed of an object, usually a transport vehicle. They include: Wheel speed sensors; Speedometers; Pitometer logs; Pitot tubes; Airspeed indicators; Piezo sensors (e.g. in a road surface) LIDAR; Ground speed radar; Doppler radar; ANPR (where vehicles are timed over a fixed distance)
The Joint Electronics Type Designation System (JETDS), which was previously known as the Joint Army-Navy Nomenclature System (AN System. JAN) and the Joint Communications-Electronics Nomenclature System, is a method developed by the U.S. War Department during World War II for assigning an unclassified designator to electronic equipment.
The device then looks at the contrasting reflectivity of the light at certain positions on the form. It will detect the black marks because they reflect less light than the blank areas on the form. Some OMR devices use forms that are printed on transoptic paper. The device can then measure the amount of light that passes through the paper.
Newer speed detection devices use pulsed laser light, commonly referred to as LIDAR, rather than radio waves. Radar detectors, which detect radio transmissions, are unable to detect the infrared light emitted by LIDAR guns, so a different type of device called a LIDAR detector is required. However, LIDAR detection is not nearly as effective as ...
In general, detection is the action of accessing information without specific cooperation from with the sender. In the history of radio communications, the term "detector" was first used for a device that detected the simple presence or absence of a radio signal, since all communications were in Morse code.
