  • Patent number: 10712730
    Abstract: Methods aim to reduce and/or eliminate the need for shims in manufacturing assemblies, such as in manufacturing of aircraft wings. Exemplary methods include predicting a set of predicted manufacturing dimensions within a range of predetermined allowances for a first part, manufacturing the first part, scanning the first part to determine a set of actual manufacturing dimensions for the first part, and at least beginning manufacturing a second part before the scanning the first part is completed. The second part may be manufactured based on the set of predicted manufacturing dimensions for the first part. Once the scan of the first part is completed, the set of predicted manufacturing dimensions may be compared to a set of actual manufacturing dimensions to check for any non-compliant deviances between the predicted and actual manufacturing dimensions. Repairs and local re-scans may be performed in the areas of the non-compliant deviances, which may streamline manufacturing.

    Abstract: Introduced herein are various techniques for displaying virtual and augmented reality content via a head-mounted display (HMD). The techniques can be used to improve the effectiveness of the HMD, as well as the general experience and comfort of users of the HMD. An HMD may increase and/or decrease the resolution of certain areas in digital content that is being viewed to more accurately mimic a user's high resolution and low resolution fields of view. For example, the HMD may monitor the user's eye movement to identify a focal point of the user's gaze, and then increase the resolution in an area surrounding the focal point, decrease the resolution elsewhere, or both. Predictive algorithms could also be employed to identify which areas are likely to be the subject of the user's gaze in the future, which allows the HMD to present the regionally-focused content in real-time.

    Abstract: A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a speed estimate from their temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Three methods are given to determine the azimuth and range of a projectile, one for clear atmospheric conditions and two for nonhomogeneous atmospheric conditions. The first approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. The second calculates this angle using a different algorithm. The third uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate.

  • Patent number: 8280113
    Abstract: A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a time-varying speed estimate from their time-varying temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Various methods are given to determine the azimuth and range of a projectile, both for clear atmospheric conditions and for nonhomogeneous atmospheric conditions. One approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. A second uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate.

  • Patent number: 8186589
    Abstract: The present invention relates to a hierarchical system and method for task assignment (TA), coordination and communication of multiple Unmanned Aerial Vehicles (DAV's) engaging multiple attack targets and conceives an ad-hoc routing algorithm for synchronization of target lists utilizing a distributed computing topology. Assuming limited communication bandwidth and range, coordination of UAV motion is achieved by implementing a simple behavioral flocking algorithm utilizing a tree topology for target list routing. The TA algorithm is based on a graph-theoretic approach, in which a node locates all the detectable targets, identifies them and computes its distance to each target. The node then produces an attack plan that minimizes the sum of distances of the UAV's in the subtree of a given node to the targets.

  • Patent number: 8025230
    Abstract: The present invention increases the survivability of a helicopter by prioritizing a threat engagement sequence for a laser-based countermeasure system based on the determined relative lethality of each detected visually trained threat (e.g., small arms fire). The system and method defines a plurality of threat effectiveness merit factors, or lethality factors, that are determinable from available helicopter navigation and sensor data, to quantify the danger associated with each detected threat. The system and method then combines the defined lethality factors using a mathematical function, such as a merit function, to numerically quantify the level of threat posed by each threat. The calculated threat values for each of the detected threats are compared to prioritize the threats for engagement by a laser-based countermeasure system, such as a Visual Acquisition Disrupter (VAD) system.

  • Patent number: 7963442
    Abstract: A Reconfigurable Nose Control System (RNCS) is designed to adjust the flight path of spin-stabilized artillery projectiles. The RNCS uses the surface of a projectile nose cone as a trim tab. The nose cone may be despun by the action of aerodynamic surfaces, to zero spin relative to earth fixed coordinates using local air flow, and deflected by a simple rotary motion of a Divert Motor about the longitudinal axis of the projectile. A forward section of the nose cone having an ogive is mounted at an angle to the longitudinal axis of the projectile, forming an axial offset of an axis of the forward section with respect to the longitudinal axis of the projectile. Another section of the nose cone includes another motor, the Roll Generator Motor, that is rotationally decoupled from the forward section and rotates the deflected forward section so that its axis may be pointed in any direction within its range of motion.
