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: 11780445Abstract: Embodiments describe a vehicle configured with a brain machine interface (BMI) for a vehicle computing system to control vehicle functions using electrical impulses from motor cortex activity in a user's brain. A BMI training system trains the BMI device to interpret neural data generated by a motor cortex of a user and correlate the neural data to a vehicle control command associated with a neural gesture emulation function. A BMI system onboard the vehicle may receive a neural data feed of neural data from the user using the trained BMI device, determine, a user intention for a control instruction to control a vehicle infotainment system using the neural data feed, and perform an action based on the control instruction. The vehicle may further include a headrest configured as a Human Machine Interface (HMI) device that reads the electrical impulses without invasive electrode connectivity.Type: GrantFiled: January 13, 2020Date of Patent: October 10, 2023Assignee: Ford Global Technologies, LLCInventors: Ali Hassani, Aniruddh Ravindran, Vijay Nagasamy

Patent number: 11751784Abstract: Example embodiments described in this disclosure are generally directed to detecting drowsiness in a driver of a vehicle. In an example method, a driver drowsiness detection system receives a motor cortex signal from a brain activity monitoring element attached to the driver. The brain activity monitoring element can be a cortical implant, for example. The driver drowsiness detection system evaluates the motor cortex signal to identify an anatomical part of the driver (eyes, for example) that is associated with a brain activity. The driver drowsiness detection system then uses a drowsiness detection device placed in the vehicle for evaluating a physical activity of the anatomical part. The evaluation may be carried out by using a camera directed upon the driver's eyes, for example. The driver drowsiness detection system determines a drowsiness state of the driver based on the evaluation and assigns a sleep risk score.Type: GrantFiled: March 18, 2020Date of Patent: September 12, 2023Assignee: Ford Global Technologies, LLCInventors: Walter Talamonti, Ali Hassani, Aniruddh Ravindran

Publication number: 20220063631Abstract: A sensor-fusion approach of using Brain Machine Interface (BMI) to gain a higher resolution perspective of chassis input control is described according to the present disclosure. Traditional chassis control inputs, such as steering wheel, brake and driver state monitoring sensors can calculate input but often cannot well predict intent. By interpreting well known motor command signals, it can become clear how much chassis input the driver was intending to provide. The BMI may monitor motor cortex to identity when a muscular movement is imminent, such as the movement of the arms to grasp the steering wheel. This combination would enable faster and more precise intent calculation. Additionally, information from driver wearable devices may be used to supplement the determination. This allows for a faster response and well as better integration with the driver.Type: ApplicationFiled: August 31, 2020Publication date: March 3, 2022Applicant: Ford Global Technologies, LLCInventors: Ali Hassani, Aniruddh Ravindran, Vijay Nagasamy

Publication number: 20200038653Abstract: Brain impairment, for example due to stroke, is corrected in order to improve body movement. An fNIRS device is positioned over the motor cortex of non-impaired individuals, and blood oxygen in locations of the brain is analyzed to determine brain activity corresponding to a particular body movement. The movements are statistically analyzed, and are compared with fNIRS data gathered from a movement impaired individual attempting the same movement. A weighted value corresponding to the desired brain activity is generated using the statistical analysis, and is graphically displayed to the movement impaired individual during the attempts. This produces a feedback loop relating to the movement which can be repeated to produce brain plasticity in the impaired individual to facilitate the movement. Additionally, correct brain activity can be used to cause the application of an electrical signal to muscles of the body to produce the desired movement.Type: ApplicationFiled: December 20, 2016Publication date: February 6, 2020Inventors: Ranganatha SITARAM, Janis Jaelynn DALY, Mohit RANA, Aniruddh RAVINDRAN
