Abstract: Radiation systems, including apparatuses and methods, for providing multiple independent RF electron accelerators with RF power from a single RF generator. The radiation systems may be employed in radiation treatment systems for treating subject objects by irradiating them from different directions and in inspection systems for producing images of the contents of a container or other volume in multiple planes using RF electron accelerators that receive RF electromagnetic power from a single RF generator. The radiation systems include RF drive subsystems each having a 3 dB directional coupler connected between an RF generator and RF electron accelerators. Each 3 dB directional coupler divides RF electromagnetic power received from the RF generator into equal or unequal portions for delivery to respective RF electron accelerators.

Abstract: A radiographic inspection system for inspecting subject objects using charged particle beams having pulses of charged particles with different energy levels from pulse to pulse. A phase shifter thereof enables adjustment of the RF power delivered to first and second accelerating sections thereof from a single RF source without adjustment of the RF power generated by the RF source. The system also enables the generation of images of the contents of a container from multiple directions and in multiple planes, and allows the discrimination of materials present in the container.

Abstract: A cryptographic container security system for enabling the secure transportation of a container from a sender site to a receiver site. The system includes, in the exemplary embodiment, apparatuses and methods for generating pre-transportation and post-transportation fingerprints of a container being transported, for encrypting and decrypting the pre-transportation fingerprint, and for comparing pre-transportation and post-transportation fingerprints, and for comparing the decrypted pre-transportation fingerprint and the pre-transportation fingerprint. The pre-transportation and post-transportation fingerprints are generated from fingerprint data, including, without limitation, the aggregate gamma flux and aggregate effective Z-number determined for the container by multi-energy scanning systems located, respectively, at sender and receiver sites.

Abstract: The present invention comprises an optical communication system, including apparatuses and methods, which use coherence multiplexing to optically multiplex different signals that may have varying protocols or operate at different speeds, onto a single wavelength channel which is dense wavelength division multiplexed with other channels for optical communication. The apparatuses and methods of the optical communication system also enable the dropping and inserting of selected single protocol signals at intermediate sites of a DWDM communication link which is less costly and makes less wasteful use of optical wavelength channels for the communication of lower data rate information.
