Patent number: 12055940Abstract: The present invention extends to methods, systems, and computer program products for path planning for autonomous moving devices. Aspects of the invention include planning a path for a mobile robot to move autonomously in an environment that includes other static and moving obstacles, such as, for example, other mobile devices and pedestrians, without reference to a prior map of the environment. A planned path for a mobile robot can be determined, adjusted, and adapted using diffusion maps to avoid collisions while making progress towards a global destination. Path planning can include using transition probabilities between grid points to find a feasible path through parts of the environment to make progress towards the global destination. In one aspect, diffusion maps are used in combination with a receding horizon approach, including computing diffusion maps at specified time intervals.Type: GrantFiled: January 24, 2018Date of Patent: August 6, 2024Assignee: Ford Global Technologies, LLCInventors: Sanghyun Hong, Jianbo Lu, Dimitar Filev

Patent number: 11954253Abstract: Embodiments describe a system configured with a brain machine interface (BMI) system implemented in a vehicle for performing vehicle functions using electrical impulses from motor cortex activity in a user's brain. The system uses fuzzy states for increased robustness. The fuzzy states are defined by sets of Gaussian kernel-type membership functions that are defined for steering and velocity action function states. The membership functions define fuzzy states that provide overlapping control tiers for increasing and decreasing vehicle functionality. An autonomous vehicle may perform control and governance of transitions between membership functions that may overlap, resulting in smooth transitioning between the states.Type: GrantFiled: August 13, 2020Date of Patent: April 9, 2024Assignee: Ford Global Technologies, LLCInventors: Ali Hassani, Aniruddh Ravindran, Dimitar Filev, Vijay Nagasamy

Patent number: 7966151Abstract: A constraint analysis and reliability agent executes a method for analyzing operation of a manufacturing asset, and includes the steps of collecting operation data for a machine over a plurality of predetermined time periods. The operation data includes a plurality of mutually exclusive events that describe operation of the machine. For each of the predetermined time periods, it is determined whether the machine is in an “ON” or an “OFF” state. Data for the “OFF” states is removed from the collected data to generate a filtered data set. Reliability information is then generated based, at least in part, on the filtered data set. This facilitates predictions of future machine operation.Type: GrantFiled: October 24, 2006Date of Patent: June 21, 2011Assignee: Ford Motor CompanyInventors: Dimitar Filev, Paul E.
