A time-domain reflectometer (TDR) is an electronic instrument that uses time-domain reflectometry to characterize and locate faults in metallic cables. It can also be used to locate discontinuities in a connector, printed circuit board, or any other electrical path. The equivalent device for optical fiber is an optical time-domain reflectometer.
Surveyor 7 was the seventh and last lunar lander of the American unmanned Surveyor program sent to explore the surface of the Moon. A total of 21,091 pictures were transmitted to Earth.
The GATOR mine system is a United States military system of air-dropped anti-tank and anti-personnel mines developed in the 1980s to be compatible with existing cluster dispensers. It is used with two dispenser systems—the Navy 230 kg (500 lb) CBU-78/B and the Air Force 450 kg (1,000 lb) CBU-89/B. Additionally the mines are used with the land- and helicopter-based Volcano mine system.
Minesweeping is the practice of the removal of explosive naval mines, usually by a specially designed ship called a minesweeper using various measures to either capture or detonate the mines, but sometimes also with an aircraft made for that purpose. Minesweeping has been practiced since the advent of naval mining in 1855 in the Crimean War. The first minesweepers date to that war and consisted of British rowboats trailing grapnels to snag the mines.
Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes.
The POMD-1 is a cylindrical scatterable Bulgarian anti-personnel mine, used in the KNURS-DM 122 mm rocket fired from the BM-21 vehicle mounted rocket launcher. In one 122 mm rocket, a single POMD-1 mine was carried along with 16 PMD-1 AP pressure mines, and four TMD-1 anti-tank mines.
The SAPM is a Chinese scatterable anti-personnel fragmentation mine. It is typically deployed from either 122 mm rockets or truck based mine layers. Once the mine hits the ground, two tripwires are deployed to a maximum distance of 10 meters from the mine. Tension on these wires triggers the mine.
The VS-SATM1 is an Italian scatterable anti-tank landmine that was produced by Valsella Meccanotecnica SpA. The mine can be scattered by a GRILLO-128 man-portable single-tube launcher system or a VS-MDH helicopter based system. The mine has six pop-out fins which slow its descent and improve the dispersion characteristics.
The 4AHM-100, AHM-200, AHM-200-1, AHM-200-2, PMN-150, and PMN-250 are Bulgarian directional fragmentation mines that can be used with proximity fuzes to function as anti-helicopter mines.
The FFV 028 is a series of steel cased Swedish anti-tank mines that use electronic fuzes. The mines are circular, with a large Misznay Schardin effect warhead in the center of the mine, with the fuzing and sensor electronics located in the dead space above the main charge. The design of the mine dates from the 1970s and uses a magnetic influence sensor to detonate the mine, making it able to attack the full width of armoured vehicles.
Curb feelers or curb finders are springs or wires installed on a vehicle which act as "whiskers" to alert drivers when they are at the right distance from the curb while parking.
The BM/85 is an Italian blast resistant bounding anti-personnel mine that was produced by Tecnovar italiana SpA. The mine is cylindrical with a three pronged tilt/pressure fuze on the top with a central post for attaching a tripwire. A plastic safety clip prevents the fuze from tilting when in transit. Once the pressure clip is removed the mine is armed. Once the fuze is pulled sideways by a trip wire or by downward pressure, the mine is triggered. A small charge launches the mine to a height of about 0.45 meters where it explodes scattering 1,000 fragments to a lethal radius of about 25 meters.

The M432 is a Portuguese bounding anti-personnel mine, which traces the roots of its design to the Second World War German S-mine, although it is probably more directly related to the Belgian NR 442 mine and United States M16 mine. As of 2004, all operational stocks of the mine have been destroyed, although some may have been retained for training purposes.
The MN-121 is a Polish scatterable anti-tank mine, externally similar to the German AT-2 mine. The mine is cylindrical with ten wire legs which fold outward to keep the mine upright. The mine uses a magnetic influence fuze, which triggers the mine when a vehicle passes over it. The mine also has an anti-handling device which triggers the mine if it is moved. The mine's warhead is a shaped charge design containing approximately 700 grams of RDX. The manufacturer claims that it is capable of penetrating 60 millimeters of armour at an offset of half a meter.
Automated airport weather stations are automated sensor suites which are designed to serve aviation and meteorological observing needs for safe and efficient aviation operations, weather forecasting and climatology. Automated airport weather stations have become part of the backbone of weather observing in the United States and Canada and are becoming increasingly more prevalent worldwide due to their efficiency and cost-savings.
The MW-1 is a German munitions dispenser similar to the British JP233. It is designed to be carried on the Tornado IDS, although it can be carried on the F-104 Starfighter and the F-4 Phantom. The MW-1 started to be phased out after the German Government ratified the Convention on Cluster Munitions in 2009.
The MineCam is a remote exploration camera built by I.A.Recordings. It is used for mine shaft exploration and other similar environments. It was originally conceptualized in 1988, and since went under several design revisions. The name MineCam, is a pun on MiniCam, an early hand-held broadcast camera built by CBS Laboratories.
The Sony Xperia XZs is an Android smartphone manufactured and marketed by Sony. Part of the Xperia X series, the device was announced to the public along with the Xperia XZ Premium at the annual Mobile World Congress last February 2017.
