Probabilistic sampling method for track association
A method for solving the track association problem updates and samples a marginal association likelihood conditioned upon existing track assignments and marginalized over possible sensor biases to assign tracks and build a full association hypothesis. The “sampling” is repeated multiple times for a given seed track pair and for different seed track pairs to quickly generate hypotheses that approximate the solution space. The probabilistic track association includes a plurality of likely full association hypotheses and a soft association matrix that probabilistically reflects the likelihood of the track association for a pair of sensors. Efficacy can be enhanced by sensing and processing non-metric features (e.g. size, shape, color) to supplement the metric features (e.g. location, velocity). Efficiency may be enhanced by prioritizing the list of seed track pairs in order of decreasing likelihood, saving only full association hypotheses that are both unique and close to the current most likely hypothesis and terminating the search based on a staleness criteria. Probabilistic sampling may be used for such diverse applications as missile defense, autonomous vehicles and package handling. |

Reducing synchronization reliance in marking
Memory reclamation is tailored to avoid certain synchronization instructions, speeding concurrent garbage collection while preserving data integrity and availability. Garbage collection reclaims objects no longer in use, or other unused areas of memory. Pointers are partitioned into address portions holding address values and non-address portions having a special bit. Marking code writes only the non-address portions, setting the special bit as a mark reference, relocation candidate, etc. Mutator threads may concurrently mutate the entire pointer to update the address, but mutation does not cause incorrect reclamations or failure to do other operations such as relocation. Meanwhile, execution speed is increased by avoiding CAS (compare-and-swap instructions or compare-and-set) synchronization instructions. Non-CAS yet nonetheless atomic writes are used instead. Mutators run in user or kernel address spaces. Partitioned pointers and their use may be enclosed to avoid runtime errors by code that expects references to be in a canonical non-partitioned form. |

Vehicle localization augmentation for dismounts
A Vehicle Localization Augmentation for Dismounts (VLAD), which extends the technology used by dismount localization systems to include the capability of riding and aligning inertial systems to a vehicle. VLAD takes the proven Warfighter's Integrated Navigation System (WINS) and, when appropriate, increases capabilities by investigating aiding sensors, algorithms, and frameworks to align dismount inertial sensors to vehicle inertial sensors. The two focuses of this effort are initialization and maintaining the solution quality. Initialization is the process where an inertial unit calculates sensor biases in an effort to minimize systemic errors in the localization solution. This process is highly related to the sensor being used. High quality sensors, for example, perform a gyrocompassing operation on initialization. Gyrocompassing measures the Earth's rotation and gives the absolute heading relative to the Earth. On man-portable inertial systems, this process can take 15 minutes. |
