Patent number: 11451608Abstract: Embodiments disclosed herein may relate to systems and methods for managing work flow data collection for users across a wide area network comprising a diverse set of devices and processes and unifying the work process to be device agnostic. Embodiments disclosed herein may allow a single process having multiple steps to be retrieved and continued across multiple channels and devices with apparent continuity to the end-user. The status of each process step is tracked and the inputs are stored, providing the system with the requisite information when users continue processes on a different channel or device from the original channel or device. The system may host and execute processes that may be presented and manipulated across the various channels and devices, but without requiring engineers and developers to write or otherwise tailor software applications and network configurations to facilitate or allow multi-channel interactions.Type: GrantFiled: June 5, 2020Date of Patent: September 20, 2022Assignee: United Services Automobile Association (USAA)Inventors: James T.

Patent number: 10744906Abstract: Example embodiments presented herein are directed toward a seat assembly, and corresponding method, for seat retraction in a vehicle during an autonomous driving mode. Seat refraction is provided by detecting a user initiated input for the retraction. Thereafter, a front seat is refracted such that an occupant of the front seat is out of reach of at least one driving control input device, for example, a steering wheel, pedals or a gear shift, during an autonomous driving mode. Such seat retraction prevents the occupant from providing inadvertent driving inputs to the driving control input devices during the autonomous driving mode.Type: GrantFiled: September 17, 2015Date of Patent: August 18, 2020Assignee: VOLVO CAR CORPORATIONInventors: Ichiro Sugioka, John Downs, Andreas Zinn, Douglas Hall Frasher
