  • SYSTEM AND METHOD FOR SOLAR VAPOR EVAPORATION AND CONDENSATION
    Publication number: 20240336494
    Abstract: A solar vapor generator system and method are provided. In some embodiments, the system has near perfect energy conversion efficiency in the process of solar vapor generation below room temperature. Remarkably, when the operation temperature of the system is below that of the surroundings, the total vapor generation will be higher than the upper limit that can be produced by the input solar energy.
    Type: Application
    Filed: September 20, 2022

  • Freeway queue warning system
    Patent number: 10783787
    Abstract: A method includes using sensors to collect information about vehicles on a road and determining a plurality of crash probabilities based on the collected information. Each crash probability indicates a probability of a vehicular crash on the road at a respective point in time. The plurality of crash probabilities is averaged to form an average crash probability and the average crash probability is used to determine when to provide a message to a controller of a vehicle.
