Flexnet™ is a Unattended Ground Sensor capability, [9] from the Swedish company Bertin Exensor, subsidiary of Bertin Technologies. It includes sensors with embedded processing, GPS, and radio communication. Those sensors are based on seismic-acoustic detection, passive infrared, electro-optical and magnetic detection techniques.
McQ Inc. is a defense and electronics company in Fredericksburg, Virginia, that specializes in remote monitoring and surveillance equipment and systems for government and industry. McQ Inc designed and produces the OmniSense unattended ground sensor system equipment in use as part of currently deployed Unattended Ground Sensors (UGS).
Part of the AN/GSQ-187 Improved Remote Battlefield Sensor System (I-REMBASS) is a passive acoustic sensor, which, with other MASINT sensors, detects vehicles and personnel on a battlefield. [24] Passive acoustic sensors provide additional measurements that can be compared with signatures, and used to complement other sensors.
A bistatic remote sensing system would separate source 3a from sensor 3b; a multistatic system could have multiple pairs of coupled sources and sensors, or an uneven ratio of sources and sensors as long as all are correlated. It is well known that bistatic and multistatic radar are a potential means of defeating low-radar-observability aircraft.

The Wide Area Tracking System (WATS) is a prototype network for detecting a ground-based nuclear device [22] such as a nuclear "briefcase bomb." WATS is being developed at the Lawrence Livermore National Laboratory (LLNL). WATS would be made up of wireless gamma and neutron sensors connected through a communications network.
Unattended Transient Acoustic MASINT Sensor (UTAMS) Mortar, Rocket, Explosive Locator System is an acoustic localization sensor system developed by the Sensors and Electronic Devices Directorate (SEDD) of the U.S. Army Research Laboratory (ARL) in 2004. [1]
An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth. It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 kΩ (sample of IEC standard for medical applications). The main advantage ...
