Rigid Marking Foam. Rigid Marking Foam is a tool for deminers to mark, extract, and in some cases, neutralize a mine. This polyurethane substance is dispensed around a mine, encapsulating it and forming a hard, environmentally safe shell. In some instances this neutralizes the mine fuse to prevent accidental activation. A rope may be placed within the hardening foam, thus permitting the mine to be extracted from a distance. This item is not yet fully tested against tripwire-fused mines. It is not intended for use against AT mines or for underwater use. These kits are classified as hazardous material.

Blast Fragment Container. The Blast Fragment Container was developed to contain fragments from a mine blast and vent blast forces upward and away from high value assets that may be nearby. Operators place the container over the mine and explosive charge and follow normal demolition procedures. The containers are made of dry rolled S-2 glass and 100% vinyl ester resin. They are 50.8 cm high and 61 cm in diameter, and weigh approximately 27 kg. Additional protection may be added by sliding a thin outer layer tube over the original container. These tubes are 50.8 cm high, 66 cm in diameter and weigh approximately 11.8 kilograms. In tests, the Blast Fragment Container survived the blast and fragmentation effects from selected mines and 0.46 kg of C-4 explosive. Containers with additional outer shells can be used up to five times against fragmentation mines, and up to ten times on smaller AP mines, depending on the demolition charge. This device is only usable against AP mines and has not been tested against other UXO. Heavy vegetation may interfere with the placement of the container.

Air Spade. The Air Spade comprises a commercial air compressor, a gasoline or diesel engine, and an air nozzle that creates a specially focused jet of air propelled at Mach 1.5. Its objective is to provide a safe standoff capability to rapidly excavate AP and AT mines, doing so at a faster rate than any other current method. The air spade is simple to operate and transport. It is not intended for use in heavily vegetated areas, in areas with motion sensitive fused mines, and may prove difficult to handle in severe terrains. Prototypes have been deployed to Afghanistan and Cambodia. One unit has been purchased for Angola and four for Ecuador.

Universal Power Manager.   The Universal Power Manager (UPM) was designed to help deminers determine battery status in the field and reduce the logistical burden of battery replacement. The UPM is a rugged rechargeable power supply capable of operation in harsh environments and is intended to replace disposable batteries. The UPM can convert input voltages from standard and poorly regulated AC, DC, and solar panels. It can also estimate the remaining life of disposable batteries. The UPM automatically handles unregulated inputs of 3 to 30 V DC, including solar cells and 100-240 V AC at 50-60 Hz. The UPM can power small devices like walkie-talkies and cell phones from a variety of input sources for emergency situations. It cannot recharge alkaline or other non-rechargeable batteries and has a 20-watt maximum output.
