  • Patent number: 11978887
    Abstract: A method of preparing cathode particles using a co-precipitation reaction in a reactor is disclosed. A feed stream (a) containing metal cations is fed into the reactor, and a feed stream (b) containing anions is fed into the reactor, wherein a ratio of the metal cations in the feed stream (a) is continuously changed from A1 at time t1 to A2 at time t2. The feed stream (a) and the feed stream (b) are contacted in the reactor to form precipitated precursor particles, and at least one transition metal component in the particle has a non-linear continuous concentration gradient profile over at least a portion along a thickness direction of the particle.

  • Patent number: 11432799
    Abstract: A fully automatic ultrasonic scanner and a scan detection method is provided. The fully automatic ultrasonic scanner comprises: an ultrasonic probe (4); a driving system (5) for driving the ultrasonic probe (4) to move; and a flexible structure on which the ultrasonic probe (4) is mounted, wherein the flexible structure enables the ultrasonic probe (4) to be always along a curve of a skin surface and keep perpendicular to the skin surface during scanning. The flexible structure of the fully automatic ultrasonic scanner has self-adaptive effect, can adjust the scan trace and the probe angle in real time according to different curves of the human body, and ensure that the ultrasonic probe (4) scans against the skin surface and keeps perpendicular to the skin surface, which improves the quality of the scanned images, so as to enhance the detection rate and accuracy rate of early screening, and reduces the probability of missed diagnosis.

  • Patent number: 9848419
    Abstract: A method for matching a ground station to an aerial vehicle for establishment of a backhaul link to an airborne network involves: (i) determining location information for a ground station that is configured to provide a backhaul link to an airborne mesh network, (ii) determining flight data for one or more of the aerial vehicles in the airborne mesh network, (iii) based at least in part on the combination of (a) the location information for the ground station and (b) the flight data for the one or more of the aerial vehicles, selecting a flight with which the ground station should establish a backhaul link to the airborne network, and (iv) generating a link-assignment message that comprises instructions for the ground station to establish a backhaul link between the ground station and an aerial vehicle carrying out the selected flight.
