Abstract
Abstract A mine effects simulator system for simulating the operation and encounterf land mines and their potential effects on an armored vehicle. The system utilizes an authentic land mine activation mechanism, radio transmitter and logic circuitry and provides a radio frequency signal when activated by the proximity of an armored vehicle. The armored vehicle has a receiver device which receives the signal to determine a "hit" or "kill" based upon the time of the mine detonation with respect to mine to vehicle position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
A mine effects simulator system, for simulating the operation and encounter of land mines and their potential effects upon an armored vehicle, comprising: a land mine simulation device having an authentic land mine activation mechanism, radio transmitter and logic circuitry, said land mine simulation device providing a radio frequency signal when activated by the proximity of an armored vehicle; and a receiver device mounted on said armored vehicle for receiving said radio frequency signal from said mine simulation device to determine a "hit" or "kill" said receiver including logic circuitry for determining the type of kill effect on the vehicle as a function of time of mine detonation with respect to mine to vehicle position.
Claim 2
Dependent Claim
115 words
A mine effects simulator system, for simulating the operation and encounter of land mines and their potential effects upon an armored vehicle, comprising: a land mine simulation device having an authentic land mine activation mechanism, radio transmitter and logic circuitry, said land mine simulation device providing a radio frequency signal when activated by the proximity of an armored vehicle; and a receiver device mounted on said armored vehicle for receiving said radio frequency signal from said mine simulation device to determine a "hit" or "kill" said receiver including logic circuitry for determining the type of kill effect on the vehicle as a function of time of mine detonation with respect to mine to vehicle position.
Claim 3
Dependent Claim
56 words
The system of claim 1 wherein said mine simulation device logic circuitry determines the type of "kill" detonation of the mine with respect mine to vehicle position at the time of mine detonation said logic circuitry placing a code indicating the type of "kill" detonation on said radio frequency signal provided by said mine simulation device.
Claim 4
Dependent Claim
20 words
