A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
A mechanically powered flashlight (UK: mechanically powered torch) is a flashlight that is powered by electricity generated by the muscle power of the user, so it does not need replacement of batteries, or recharging from an electrical source.

Conceptual through-beam system to detect unauthorized access to a secure door. If the beam is interrupted, the detector triggers an alarm. A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are largely used in ...
Integrated into the ESV are obstacle neutralization and lane marking systems and mine detection devices. The ESV with its attachments provides a partial solution to the obstacle clearance role, primarily for clearance of hastily emplaced mines on hard surfaces and rubble, plus will enable the Engineer squad to control future robotic based systems.
It was an ionization detector powered by a single 9-volt battery. [10] It cost about US$125 (equivalent to $980.72 in 2023) and sold at a rate of a few hundred thousand units per year. [8] Several developments in smoke detector technology occurred between 1971 and 1976, including the replacement of cold-cathode tubes with solid-state electronics.
A typical route clearance package, or RCP, consists of a sapper platoon, an EOD team, at least one medic, and a HEMTT wrecker staffed by a team of mechanics. RCPs are clearly recognized by troops as they use the Husky vehicle-mounted mine detector, as well as the Buffalo (mine protected vehicle). While these vehicles provide superb protection ...
