Abstract: A ground penetration radar (GPR) antenna system is integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine. The system includes a GPR antenna and an inertial measurement unit (IMU). The GPR antenna includes a rectangular hollow enclosure made of a conductive material defining a cavity therein and is affixed to a bucket of the digging machine. The IMU is mounted to the hollow enclosure and provides a space trajectory over time of the GPR antenna on the bucket as the digging machine is operated.

Abstract: A ground penetration radar (GPR) antenna system is integrated into a digging machine such that the system is configured to remain operable under the same environmental conditions as the machine. The system includes an RF antenna and an antenna monitor. The antenna includes a rectangular hollow enclosure made of a conductive material defining a cavity therein and is affixed to a bucket of the digging machine. The antenna monitor is rigidly connected to the hollow enclosure and monitors inertial antenna location and/or movement.

Abstract: A system and a method for therapeutic treatment of biological tissue using weak magnetic fields. In accordance with one embodiment, the system comprises: a magnetic field transducer for transducing electrical currents into magnetic fields; a sheet or disk made of high-permeability material and disposed on one side of the magnetic field transducer, but removable therefrom; and a current source coupled to the magnetic field transducer for supplying electrical current thereto. A magnetic beam produced by the interaction of the sheet of high-permeability material with a magnetic field produced by the magnetic field transducer has a profile which is a function of the composition, geometry and thickness of the high-permeability material. Preferably the high-permeability material has a relative permeability value greater than 10,000.

Abstract: The present invention provides an article tracking and control system that records articles when they are entered into or removed from a case. Each article is tagged with an RFID tag and is identified individually by the system. The system comprises: wireless identification device attached to each article; a case for containing the tagged articles; an antenna mounted close to the cover of the case so that the antenna is able to read the tagged articles entering or being removed from the case, while tagged articles inside the case are not detected by the antenna; processing means for tracking each entry and removal of a tagged article into or out of the case; and means for visualizing reports and/or alerts regarding the status of tagged articles inside the case.

Abstract: An expendable, stand-alone, off-board Electronic Counter-Measure system, airborne RF decoy aimed to provide airborne platforms with protection against multiple radar-based threats including Air-to-Air and Surface-to-Air missiles both active and semi-active ones. The airborne RF decoy has the mechanical outline of standard chaff and flare decoys and is safely ejected from any platform by pyrotechnic elements. The airborne RF decoy deceives enemy radar-based threats as follows: immediately after its ejection from the protected airborne platform, the decoy activates an energy source, stabilizes its path, acquires illuminating signals and analyzes threat parameters. Then the decoy alters the received signals to generate an authentic false target and transmits a deceiving signal towards the radar threat. The radar threats locks on the decoy and follow its path.
