    Abstract: A system and method for authenticating a physical object. The method may include the steps of: (1) encoding a feed material with randomized information; (2) forming the object with the feed material such that one or more portions of the object have respective randomized signatures based upon at least some of the randomized information of the feed material; (3) reading the respective randomized signatures at the one or portions of the object; (4) creating a profile of the respective randomized signatures at the one or more portions of the object based upon information from the reading; (5) transporting the physical object to an authenticator, and transmitting the profile to the authenticator; (6) reading the respective randomized signatures at the one or more portions of the object by the authenticator; and (7) comparing the reading by the authenticator to the profile received by the authenticator to thereby authenticate the physical object.

    Abstract: A distributed secured database system includes a ledger, a transmitting device, edge devices, and a time synchronization source. An evolving nonce is generated at the transmitting device and the edge devices. The evolving nonce is time-synced across the transmitting device and the edge devices. A hash value is generated at the transmitting device and the edge devices using the evolving nonce. The hash value is verified at the transmitting device and each of the edge devices during a particular time frame. A block is added to the distributed secured database system when the hash value is verified by the transmitting device and the edge devices.

    Abstract: An EO/IR optical imaging system comprises collection optics to collect light from a scene into a collimated or near-collimated space. An imaging detector is positioned at the image plane and configured to integrate incident light (radiant flux or photons) over an image frame and readout a sequence of pixelated images at a frame rate, said detector exhibiting a saturation threshold. To prevent saturation of the imaging detector, a MEMS MMA is positioned in the collimated or near-collimated space. A secondary detector (via a pick-off) samples light from the collimated or near-collimated space multiple times per image frame. A controller responsive to the sampled light commands a percentage of the mirrors to re-direct light incident on those mirrors to a light dump and commands the remaining mirrors to re-direct light incident on those mirrors to the imaging detector. Together the mirrors adjust a fraction of light reaching the imaging detector such that the integrated incident light for a given image frame is less than the saturation threshold.

    Abstract: According to embodiments, a method of forming a coating on an article includes forming a coating including an emitting layer. The emitting layer includes an elemental isotope with a known property that can be measured by a spectroscopic method. The elemental isotope provides a distinguishing identification tag for the coating, and the coating providing a layer of protection to the substrate. The method further includes depositing the coating on a surface of a substrate of the article. The elemental isotope is a stable isotope, an unstable isotope, a neutron scattering isotope, a neutron capturing isotope, or combinations thereof.
