  • Patent number: 10780778
    Abstract: Systems and methods for balancing levels of liquid fuel among multiple vehicle-mounted fuel tanks utilize at least one control valve that is configured to admit pressurized gas into a first fuel tank while a second fuel tank is ventilated, responsive to detection of a difference of liquid fuel levels within the first and second fuel tanks. Admission of pressurized gas into one fuel tank and ventilation of another fuel tank creates a pressure imbalance that causes liquid fuel to flow through a balancing line connecting the fuel tanks. Balancing may be performed in a bidirectional manner.

  • Patent number: 10759471
    Abstract: The power steering device is configured to: apply a required assist force only from a first electric motor until a predetermined period elapses, which is a period from a time point at which a driver starts steering to a time point at which a second-electric-motor drive start condition, which is a condition for starting drive of a second electric motor, is satisfied; when the predetermined period has elapsed, apply the required assist force from the first electric motor and a hydraulic actuator; and adjust an assist force by the first electric motor so that the assist force by the first electric motor is a value obtained by subtracting an assist force by the hydraulic actuator from the required assist force. As a result, the device can be downsized, and a sufficient required assist force can be generated from an initial stage of the steering.

  • Patent number: 10751232
    Abstract: An undercarriage system couples to other vehicles, such as wheelchairs and provides mobile application-driven operation. In an exemplary application, the system may be configured to receive a push driven wheelchair and temporarily retrofit the wheelchair for motorized operation. The system includes a console for a mobile computing device that operates a software application and user interface that steers the undercarriage system for navigating through an area such as an airport or other complex. In some embodiments, the software application may provide automated navigation of the undercarriage system so that, for example, the user only needs to enter in a destination (for example, a terminal number) and the application automatically drives the system including the wheelchair to the destination. Sensors and/or cameras may detect objects or markers to guide the steering.
