Patent number: 11945112Abstract: Simulated motion of the papillary muscles in a heart simulator is provided that simulates natural motion of the papillary muscles. This improves heart valve simulation. This can be done with a six degree of freedom robotic actuator (e.g., a Stewart platform or the like) appropriately driven by a controller. This can also be done with a robotic actuator that provides constrained motion of its effector by including a mechanical linkage, as long as the resulting simulated papillary muscle motion includes time-varying position and orientation of the papillary muscle.Type: GrantFiled: March 1, 2021Date of Patent: April 2, 2024Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Y.

Patent number: 11282113Abstract: Vehicle manufacturers may leverage one vehicle of a household to gain intelligence to determine whether a new vehicle may be purchased or an existing vehicle may be replaced for the household. Techniques include identifying a home geofence space that identifies the household at the household address for the vehicle. The sensor data from the vehicle can be used to identify other vehicles within the home geofence space. When other vehicles are identified that match appropriate criteria, the other vehicles may be associated with the household. Further observation of the other vehicles and the behavior of the members of the household can be used to identify when an existing vehicle of the household may be replaced and/or a new vehicle may be purchased. Upon determining that a new or replacement vehicle may be purchased, marketing materials may be provided to the household to aid the household with purchasing the new vehicle.Type: GrantFiled: January 6, 2020Date of Patent: March 22, 2022Assignee: Ford Global Technologies, LLCInventors: Jason Joseph Woo, Jeremy Lerner, Jae Hyung Lim, Taylor Hawley, Joseph Gifford
