Patent number: 11468009Abstract: In embodiments, secure compression algorithms are provided that may be employed as a single operation on raw data to produce compressed and encrypted data. In embodiments, the algorithms described herein may be performed using any type of dictionary based encryption. In one embodiment, upon adding a new prefix to a dictionary table, the dictionary table may be permuted to randomize the entries into the table. The randomization may be based upon a permutation value generated by a deterministic pseudo-random generator and/or pseudo-random function.

Patent number: 11292456Abstract: A motion planner of an autonomous vehicle's computer system uses reconfigurable collision detection architecture hardware to perform a collision assessment on a planning graph for the vehicle prior to execution of a motion plan. For edges on the planning graph, which represent transitions in states of the vehicle, the system sets a probability of collision with a dynamic object in the environment based at least in part on the collision assessment. Depending on whether the goal of the vehicle is to avoid or collide with a particular dynamic object in the environment, the system then performs an optimization to identify a path in the resulting planning graph with either a relatively high or relatively low potential of a collision with the particular dynamic object. The system then causes the actuator system of the vehicle to implement a motion plan with the applicable identified path based at least in part on the optimization.Type: GrantFiled: January 4, 2019Date of Patent: April 5, 2022Assignees: DUKE UNIVERSITY, BROWN UNIVERSITYInventors: Daniel Sorin, William Floyd-Jones, Sean Murray, George Konidaris, William Walker
