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: A projectile including an ejectable aft fin housing assembly. The aft fin housing assembly includes aft fins that increase a distance between a center of gravity and a center of pressure of the projectile, improving passive stabilization of the projectile. Once the projectile has been passively stabilized, the aft fin housing assembly is ejected, decreasing a distance between the center of gravity and the center of pressure, improving active stabilization of the projectile.

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: A beam steering architecture for an optical sensor is based upon a pair of Micro-Electro-Mechanical System (MEMS) Micro-Mirror Arrays (MMAs) and a fold mirror. The MEMS MMAs scan both primary and secondary FOR providing considerable flexibility to scan a scene to provide not only active imaging (to supplement passive imaging) but also simultaneously allowing for other optical functions such as establishing a communications link, providing an optical transmit beam for another detection platform or determining a range to target. A special class of MEMS MMAs that provides a “piston” capability in which the individual mirrors may translate enables a suite of optical functions to “shape” the optical transmit beam.

Abstract: An optical sensor uses a MEMS MMA to scan a narrow laser beam over a transmit FOR to provide active illumination and to correct the beam profile (e.g., collimate the beam, reduce chromatic aberrations, correct the beam profile or wavefront). A staring detector senses light within a receive FOR that at least partially overlaps the transmit FOR. By completely eliminating the dual-axis gimbal, this sensor architecture greatly reduces the volume and weight of the optical sensor while avoiding the deficiencies of known systems associated with either fiber or free-space coupling of the laser beam into an existing receiver.

Abstract: Small angle optical beam steering is performed using a Micro-Electro-Mechanical System (MEMS) Micro-Mirror Array (MMA) that minimizes diffraction for a specified steering angle, Generally speaking, this is accomplished with a MEMS MMA that exhibits a “piston” capability to translate individual mirrors in addition to the tip and tilt capabilities. Adjacent mirrors can be tipped/tilted to the specified steering angle and then translated by a requisite amount to approximate a continuous surface. For a specified steering angle, the MEMS MMA is partitioned into one or more sections with each section including the maximum number of mirrors that can be grouped together and actuated to approximate a continuous surface given a maximum translation z. As a result, the only edge discontinuities exist between adjacent sections thereby minimizing distortion for a given steering angle.

Abstract: Optical sensors and particularly gimbaled optical sensors transmit an active signal at a given wavelength and receive passive signals over a range of wavelengths while controlling pointing without benefit of measuring and locating the active signal return. The sensor includes a Tx/Rx Aperture Sharing Element (ASE) is configured to block the received active signal (e.g. reflections off a target in a scene) and process only the passive emissions. These optical sensors may, for example, be used with guided munitions or autonomous vehicles.
