Abstract: A system and method for detection, tracking, classification, and/or identification of a moving object from a moving sensor uses a three-dimensional (3D) model. The system facilitates generation of a 3D model using images from a variety of sensors, in particular passive two-dimensional (2D) image capture devices. 2D images are processed to determine viewpoint and find moving objects in the 2D images. Conventional techniques or an innovative technique can be used to find segments of 2D images having moving objects. Viewpoint and segment information is used for generation of a 3D model of an object, in particular using both object motion and sensor motion to generate the 3D model.

Abstract: A firing mechanism security apparatus prevents runaway machine gun fire by first sensing rounds being fired and sensing that the trigger mechanism is not instructing the weapon to fire. A mechanical actuator may block a path of the ammunition between the ammunition storage box and the machine gun or blocks spent ammunition from being ejected. Without engaging the trigger mechanism directly, a stopper signaled by a controller or motor may move from a first position to a second position and thereby be interposed between rounds of ammunition adjacent the ammunition storage box or between the ammunition feeder and the machine gun. The ammunition feeder may, alternatively, include a mechanical actuator that receives a signal from a motor or controller, the actuator capable of blocking the feeder's advancement of ammunition. Additionally, the gun may be elevated as a safety precaution.

Abstract: A method and system are for measuring and correcting shifts in the boresight, effective focal length, and focus of an optical system that are caused by temperature variations. The method can be used for systems which can be expected to operate in situations where the temperature variations are large, e.g. a FLIR system of a fighter plane, and also where the temperature variations can be very small however high accuracy is needed. The invention is based on placing radiation emitting sources before and as close as possible to the first optical element of the optical system and measuring the thermally induced shifts of the locations of the images of the radiation emitting sources on the surface of the detector of the optical system.

Abstract: At least one solid mass of oxidizing-species-releasing material (ORM), selected as a solid oxidizer (SO), and/or as oxidizing-species-releasing burning substance (ORBS) is used as a device for enhancing the starting process of a turbine engine under various ambient conditions. The ORM is introduced into the combustion chamber of the turbine engine and the starting process of the turbine engine is initiated, by help of the igniter and in association with the ORM to enhance the starting process. In operation, an ORM selected as an SO releases gaseous oxygen when heated to decompose, while an ORM chosen as an ORBS discharges oxidizing species when ignited to burn. An ORM such as an SO or an ORBS may operate alone or in various combinations of both. The ORM is configured to release a predetermined mass flow rate of oxidizing species or of gaseous oxygen.

Abstract: A system and method for providing information for performing a registration correction for artillery employs two spaced apart optical imaging systems associated with a processing system. Outputs from the two imaging systems are monitored to detect potential shell trajectory events and then correlated to eliminate potential shell trajectory events not viewed by both optical imaging systems. Locations are determined for potential shell trajectory events viewed by both optical imaging systems. Shell firing data relating to firing of at least one shell is provided to determine at least one predicted trajectory time point for the shell, and this is used to identify a corresponding detected shell trajectory event.

Abstract: Methods and apparatus for effecting a non-uniformity correction of images of a scene obtained with an array of detector elements are disclosed. A first image of the scene having a first integration period is acquired using the array of detector elements. A second image of the scene having a different integration period is acquired, and a corrected image of the scene is generated by computing a difference of the images. In some embodiments, the first and second images are images of substantially identical scenes. According to some embodiments, the images are infrared images. Optionally, the corrected image is subjected to further correction using pixel dependent correction coefficients, such as gain coefficients. Exemplary image detection elements include but are not limited to InSb detector elements and ternary detector elements, such as InAlSb, MCT (Mercury Cadmium Telluride), and QWIP technology (Quantum Well Infrared Photodiodes).

Abstract: A method for reducing the effects of background radiation introduced into gaseous plume spectral data obtained by an aerial imaging sensor, includes capturing spectral data of a gaseous plume with its obscured background along a first line of observation and capturing a second image of the previously obscured background along a different line of observation. The parallax shift of the plume enables the visual access needed to capture the radiometric data emanating exclusively from the background. The images are then corresponded on a pixel-by-pixel basis to produce a mapping. An image-processing algorithm is applied to the mapped images to reducing the effects of background radiation and derive information about the content of the plume.
