In various example embodiments, a system and method for tracking objects in a three-dimensional space is disclosed. One method includes receiving detections representing targets, increasing a classification of a track in response to a detection matching the track, decreasing a classification of a track in response to no detections matching the track, and processing detections according to a classification level of the track.

Object tracking

A counter-swarm firework includes a shell casing, multiple streamers positioned in the shell casing, a burst charge positioned in the shell casing and configured to disperse the multiple streamers from the shell casing when discharged, a pusher plate positioned in the shell casing between the burst charge and the multiple streamers, a fire suppressant layer positioned between the burst charge and the pusher plate, and a kick charge configured to launch the shell casing and its contents prior to discharging the burst charge. The fire suppression layer may be configured to suppress heat generated by the discharge of the burst charge.

In one embodiment, a navigation system may include at least one self-describing fiducial with a communication element to communicate navigation state estimation aiding information comprising a geographic position of the self-describing fiducial with respect to one or more coordinate systems and a first navigating object to receive navigation information from an exterior system, receive navigation state estimation aiding information from the self-describing fiducial, and compare the navigation information received from the exterior system to the navigation state estimation aiding information to improve navigation parameters of the first navigating object.

Navigation using self-describing fiducials

A spring lock includes a sinusoidal spring that has one or more crests and troughs formed along a length of the sinusoidal spring, the length extending along a sliding axis, the one or more crests and troughs forming a sinusoidal spring profile. The spring lock further includes a lock bar that has a track extending along the sliding axis, the track being configured to hold the sinusoidal spring and allow the sinusoidal spring to move along the sliding axis, the track further including one or more depressions and plateaus with the depressions and plateaus forming a lock bar profile, wherein the spring lock is locked when the sinusoidal spring profile and the lock bar profile are out-of-phase and the spring lock is unlocked when the sinusoidal spring profile and the lock bar profile are in-phase.

In one embodiment, a self-describing fiducial includes a communication element that optically communicates navigation-aiding information. The navigation-aiding information may include a position of the self-describing fiducial with respect to one or more coordinate systems and the communication element communicates the navigation-aiding information to one or more navigating objects in the vicinity of the self-describing fiducial. In another embodiment, the communication element is further configured to communicate supplementary information describing a spatial relationship between the self-describing fiducial and the surrounding environment.

A method and apparatus for determining the longitudinal position of a tapered displaceable element positioned between two substantially orthogonally laterally opposing displacement sensors. A change in the longitudinal position of the displaceable element causes the sensors to each measure their distance to the displaceable element which relates directly to the local thickness and thus the longitudinal position of the displaceable element. The system factors out errors in measured lateral proximity position of the displaceable element since an erroneous proximity to one sensor is equal and opposite to an erroneous proximity to the other.

Optics positioning sensor system

An image stabilization system includes an optical assembly configured to receive electromagnetic radiation emitted by a target and produce focused image of the target; a focal plane array, the focal plane array being configured to receive the image and integrate at least a portion of the electromagnetic radiation making up the image to produce an electrical representation of the image; sensors configured to provide kinematic data; a control system receiving the kinematic data and estimating jitter-induced motion of the image on the focal plane and outputting a control signal; and actuators configured to receive the control signal and to translate the focal plane along two orthogonal axes and rotate the focal plane about a third orthogonal axis such that jitter-induced motion of the image on the focal plane is reduced.

Three-axis image stabilization system

A system for determining the longitudinal position of a displaceable element positioned between two substantially orthogonally laterally opposing displacement sensors measures a distance from each displacement sensor to the displaceable element. The displaceable element has a tapered thickness along its length. A change in the longitudinal position of the displaceable element causes the proximity sensors to each detect their distance to the displaceable element, which distances then correspond directly to the local thickness and thus the longitudinal position of the displaceable element. The system calculates the position of the displaceable element. The system can easily factor out errors in measured lateral proximity position of the displaceable element, since an erroneous proximity to one sensor is equal and opposite to an erroneous proximity to the other.
