  • Patent number: 10790537
    Abstract: A secondary battery and its preparation method, the secondary battery having a negative electrode containing a negative current collector and no negative active material; an electrolyte having an electrolyte salt and an organic solvent; a separator; a positive electrode having a positive active material layer containing a positive active material, wherein the positive active material comprises a material having a layered crystal structure; and a battery case used for packaging. Main active component of the secondary battery is the positive active material having a layered crystal structure, which is environmentally-friendly and low in cost; meanwhile, negative active material is not needed by the second battery system, thereby remarkably reducing the weight and cost of the battery and improving the battery energy density. The reaction mechanism adopted by the secondary battery significantly increases the working voltage of the battery and further improves the energy density of the battery.

  • Patent number: 10788408
    Abstract: A method for determining the diffusion radius of in-situ injection and remediation of contaminated soil and groundwater. According to the triangle method, the hole spacing is perpendicular to the groundwater flow direction, the row spacing is along the groundwater flow direction, and the flow diffusion in the groundwater during the effective time of the remediation agent reaction is considered. Under high pressure rotary injection, the remediation agent and a certain proportion of bromide ions are simultaneously injected into the aquifer as a tracer. The diffusion of the agent is determined by observing the phenomenon of slurry-returning and slurry-channeling of adjacent injection points. After the completion of the injection, the groundwater is quickly sampled in fixed depth, the tracer concentration is quickly detected on site, and the concentration of bromide ions in the groundwater is compared with the background value. Comprehensive determination determines the optimal diffusion radius.

  • Publication number: 20200257299
    Abstract: An autonomous vehicle that automatically responds to an emergency service vehicle. Perception data is captured or received by the autonomous vehicle (AV) cameras, sensors, and microphones. The perception data is used to detect lanes in a road, generate a list of objects, classify one or more of the objects, and determine a state for the classified objects. In response to detecting an emergency service vehicle such as a law enforcement vehicle, a responsive action may be planned by the AV. The responsive action may include sending an acknowledgement signal, notifying passengers of the AV, generating a planned trajectory based on the emergency service vehicle location, an emergency service vehicle detected intention, and other information. A safety check may be performed, and commands may be generated by a control module to navigate the AV along the planned trajectory. The commands may then be executed by a DBW module.
