Abstract: This disclosure provides methods and systems for dynamically detecting and tracking objects in an environment of an autonomous vehicle. In some embodiments, the method comprises: receiving image data from sensors of the autonomous vehicle, the image data comprising a plurality of images representative of objects in a field of view of the autonomous vehicle; detecting the objects in the plurality of images through an object detector; generating image embeddings for the objects detected in the plurality of images; determining similarity scores of the image embeddings of the objects that are detected in images received from two or more different sensors; identifying the objects that are detected in the images received from the two or more different sensors as a candidate object for tracking, if the objects have a similarity score of the image embeddings equal to or greater than a threshold value; and initializing a track for the candidate object.

Abstract: Disclosed herein is a system for time aligning electric power system measurements at an intelligent electronic device (IED) using samples and sample time offset from merging units. The merging units do not require access to a common time signal. The IED does not require storage of a communication latency with the merging units. The sample time offset corresponds to a latency between obtaining the sample and receipt of the sample at the IED. The IED aligns samples from various merging units using sample time offset values communicated from the merging units to the IED. The IED performs monitoring and protection functions using the time aligned samples.

Abstract: In order to incorporate minor perturbations in the simulated operation of a weapon (to simulate dispersion between batches of ammunition or individual rounds, and/or the effects of changing environmental phenomena), a variable is generated at a rate related to the type of ammunition to be simulated. For ammunition exhibiting a high degree of dispersion between rounds, the variable changes rapidly and an accurately-aimed shot is deemed a hit only if the value of the variable at that instant is less than the predetermined probability of a hit with that ammunition. In the case of ammunition exhibiting some consistency between rounds but not between batches, the variable changes slowly, and its value controls the extent of a displacement applied to a laser projector before the projector is energised and scanned for a hit/miss determination.

Abstract: For initial alignment of a simulator laser-projector with a weapon, the weapon is boresighted on a target, the projector is fitted and the laser beam is scanned stepwise across the target successively along orthogonal axes. The range of steps on each axis for which a return from the target occurs is sensed, and the step corresponding to the median of all the returns taken as the position for which the laser beam is centered on the target. These calculated positions are stored and used as the reference positions during simulated firing of the weapon. The detection of the position of a target for hit/miss determination is achieved with the same scanning and median selection procedure.
