  • Patent number: 12017685
    Abstract: An autonomous vehicle longitudinal-and-lateral control method for preventing motion sickness is disclosed. Firstly, a vehicle dynamics model is established, and the current vehicle travelling state and road surface information are determined according to the vehicle dynamics model. After the vehicle travelling state and road surface information are acquired, the desired velocity, desired acceleration, and desired wheel turning angle are output according to a driver model for reducing occurrence of motion sickness while ensuring safety and efficiency, to carry out longitudinal-and-lateral control of the vehicle.

  • Patent number: 9732057
    Abstract: A catalyst which can catalyze ring-addition reaction of CO2 and an alkylene oxide at 0˜180° C. under 0.1˜8.0 MPa to produce a corresponding cyclic carbonate, and the preparation thereof. The catalyst is a conjugated microporous macromolecule polymer complexed with cobalt, chromium, zinc, copper or aluminium, and by using the macromolecule catalyst complexed with different metals to catalyze the reaction of CO2 and alkylene oxide at normal temperature and normal pressure, a yield of the corresponding cyclic carbonate of 35%˜90% can be obtained. The catalyst is easy to recover and the re-use of the catalyst has no influence on the yield; additionally, the yield can reach over 90% by controlling the reaction conditions.

  • Patent number: 8985231
    Abstract: Methods and systems are provided for selectively displacing water from a hydraulically continuous water zone in a porous geological formation. The target zone to be displaced is defined by a hydrodynamically maintained pressure differential, which has been shown to be capable of confining an expanding injected gas zone. One or more gas injection wells and water production wells are located within the zone. During pressurized gas injection within the zone, the gas displaces water downward within the confined zone such that water is selectively produced from the target zone and the injected gas zone is confined within the hydraulically continuous water zone.

  • Publication number: 20120205096
    Abstract: A method and system for displacing water from a porous geological formation are provided. The zone to be displaced is defined by the injection of water into one or more barrier wells around the zone. One or more gas injection wells and water production wells are located within the zone. During pressurized gas injection within the zone, the barrier wells are operated to achieve a hydraulic pressure barrier surrounding the zone that is sufficient to prevent penetration therethrough by the injected gas. The well system is operated to concurrently limit gas entry into the water production well. Accordingly, the gas displaces water downward within the zone such that water is produced at the water production wells.
