Abstract: A friend or foe detection system and method is disclosed. Friend or foe warning unit 20 has a geographic locating system, a communication system for communicating with each of the warning units, and a military force detection system for detecting military forces in a combat area and has a signal routing and control circuitry 50 for controlling operations. A number of components, devices, or sub-systems, such as a transmitter/receiver radio 28, an antenna 26, a microphone 30, a speaker 32, a battery 34, a display 36, a microprocessor 38, a memory 40, a camera 56, a radar/lidar input 54, on/off switch 52, a GPS location system 45 that includes a GPS processor 46, a GPS receiver 42, a GPS antenna 44, are coupled to the circuitry 50. Display 36 provides a display to the user of the unit 20 and shows the location of friendly forces as well as unfriendly or unidentified forces in the area. Display 36 displays text messages for the user of the warning unit 20.

Abstract: A system and method for tracking, monitoring and learning prisoner or parolee behavior involves obtaining prisoner or parolee data and monitoring data for at least one individual prisoner or parolee, storing the prisoner or parolee data and monitored data into a database, learning prisoner or parolee behavior from the prisoner or parolee data and the monitored data in the database, and updating the prisoner or parolee data and the monitored data in the database. Expert system (i.e. including but not limited to fuzzy logic, reinforcement learning, neural networks, artificial intelligence, etc.) algorithms are executed for determining and analyzing deviated behavior by the prisoner or parolee. A parole level is assigned to the prisoner or parolee and it is determined whether the prisoner or parolee is to be moved up or down a parole level depending on whether the prisoner or parolee behavior does not constitute or does constitute prisoner or parolee violations.

Abstract: A comprehensive system and method for monitoring a geographic person location, periodically warning a person of emergency situations in the geographic location, and transmitting requests for assistance in emergency situations. The system comprises a warning unit 12 that is carried by the person or that is located in mobile units 20 or in buildings or houses 19. The warning unit 12 includes a geographic satellite receiver 38, a receiver circuit that receives broadcast warning signals defining dangerous situations and geographic locations of the situations, a computer controller including a processor 42 and a memory 44, an alarm indicator 64 or 66 that indicates when the person is in danger, and a transmission circuit that generates and transmits signals requesting assistance and signals warning of the dangerous situations in a vicinity of the person carrying the portable warning unit 12 along with the current geographic location of the person. The system further comprises a command center 10.
