connected to the leads that motherboard interprets the signals from the contacts for example the weight sensor will send signals to the motherboard to activate the device the motherboard will send signals to the homing units to notify that the mines have been activated the homing unit can be located at a separate area and monitored so the status of the device may be monitored at all times the base unit also contains a gps radio transponder and battery to power the unit the gps can provide the exact location of the device to monitor the location of the device at all times the motherboard takes the information from the contacts and interprets it and ignites the charge in the insert tube the motherboard also sends a signal to a nearby transponder or homing unit that alerts the monitoring station that the device has been triggered the motherboard is also connected a gps unit in the device that notifies the transponder and the monitoring station which unit has been triggered the base unit also has a trigger to ignite the insert unit 102 that is propelled out of the outer housing by an explosive charge the trigger may also be controlled remotely by the homing unit or activated by the sensors as discussed above the inner housing unit 102 acts as a lid for the cylinder the inner housing unit 102 is disposable and can be recharged with a new engine or power source explosive charge or chemical bag the insert lid 500 fits snuggly over the top of the main housing.
