20140092255 | AUTO CORRELATION BETWEEN CAMERA BANDS - A method for correlating an image to align two sensors comprising the steps of centering an imaging unit on a landmark that provides good contrast and distinct edges so as to provide a scene, taking a snapshot of the scene from both sensors, applying a Sobel edge filter to the image from both sensors to create two strong edge maps, cropping a small block of one image centered about the landmark and cross-correlating it on a larger region centered on an expected position of the landmark in the other image, and from the position of the strongest correlation peak determining the position of the center of the block from the first image, providing the difference in the alignment of the two sensors. | 04-03-2014 |
20140099823 | STACKING CONNECTOR FOR MILITARY APPLICATIONS - An electrical connector assembly adapted for military use comprising a high density maintenance connector which supports high bandwidth video export and low level maintenance functions, a lower density I/O connector, the stacking feature allows multiple branches in an ad hoc distribution center, custom to each user, and the programmability allows for identical cables/stacking connectors to be used in different configurations. | 04-10-2014 |
20140185869 | SCENE CORRELATION - A method for maintaining north comprising the steps of locating north with a north finding gyroscope, tying north to a feature in a scene, correlating the feature to a target in the field of regard of a plurality of cameras, and determining a north factor and translating the north factor into a target vector relative to north. | 07-03-2014 |
20150077547 | ATTITUDE MEASUREMENT BETWEEN OPTICAL DEVICES - A system for measuring an attitude between optical devices is disclosed. In an embodiment, the system includes a plurality of optical devices and a hub. Further, the hub includes a plurality of attitude measurement and control subsystems (AMCSs) that are aligned with a predetermined angle during factory calibration. Each AMCS is connected to one of the optical devices and each AMCS measures an attitude between an AMCS and a corresponding optical device connected to the AMCS. Furthermore, the hub includes an attitude measurement unit to measure the attitude between the optical devices based on the measured attitude between each AMCS and a corresponding connected optical device and the predetermined angle between the AMCSs. | 03-19-2015 |
20150098617 | Method and Apparatus for Establishing a North Reference for Inertial Measurement Units using Scene Correlation - A scene correlation-based target system and related methods are provided. A reference image depicts a remotely-positioned object having identifiable characteristics, wherein a reference directional vector is established relative to the reference image. A target image of a general vicinity of the remotely-positioned object has an unknown directional vector, the target image having at least a portion of the identifiable characteristics. An inertial measuring unit has a scene correlation system, wherein the scene correlation system matches the portion of the identifiable characteristics of the target image with the identifiable characteristics of the reference image, wherein a slew angle between the reference image and the target image is calculated. A target image directional vector is derived from the calculated slew angle and the reference directional vector. | 04-09-2015 |
20150143732 | SYSTEM AND METHOD OF ALIGNING AN ACCESSORY AIMPOINT TO AN AIMPOINT OF A DEVICE - A system and method of aligning an accessory aimpoint to an aimpoint of a device are disclosed. In one embodiment, an aimpoint that can be viewed through a weapon sight is projected from a device mounted on a weapon. Further, an accessory aimpoint is projected on the weapon sight by an accessory device that is mounted on the weapon in front of the weapon sight. Furthermore, the accessory aimpoint is pre-mission aligned to the aimpoint of the device by electronically adjusting a position of the accessory aimpoint to align with the aimpoint of the device on the weapon sight. | 05-28-2015 |
20150146428 | OPTICAL BENCH ASSEMBLY - An optical bench assembly is disclosed. In one embodiment, the optical bench assembly includes a housing and a cantilever optical bench for holding optical components. Further, the cantilever optical bench includes a front flange coupled to the housing and an optical bench attached to the front flange such that the optical bench is not susceptible to movements of the housing due to varying ambient conditions and resulting loads. | 05-28-2015 |
