  • Publication number: 20240105136
    Abstract: An electronic device includes a display unit, a voltage generation unit, a grayscale adjustment unit, and an overdriving unit. The display unit has a relationship curve between the transmittance and the driving voltage. The relationship curve has a predetermined voltage value corresponding to the maximum transmittance. The voltage generation unit generates a first voltage according to a first grayscale, and generates a second voltage according to a second grayscale. The grayscale adjustment unit receives a first display grayscale value, and outputs the second grayscale value when the first display grayscale value is equal to the first grayscale. The overdriving unit overdrives the second voltage corresponding to the second grayscale to obtain a first target driving voltage, and it provides the first target driving voltage to the display unit.

  • Publication number: 20220356517
    Abstract: The invention discloses a method for identifying the bacterial species and key functional genes thereof involved in antimony reduction in the soil. After consuming the original substrate by starvation culture, the sole metabolic substrate is added and the sole electron acceptor Sb(V) is provided, so that there is only one dominant electron exchange process in the system. The microorganisms metabolize and oxidize the organic substrate while coupling with the reduction of antimony, so that Sb(V) gets electrons and is reduced to Sb(III). The present invention observes the Sb(V) reduction in an anaerobic culture system of paddy soil under Sb(V) stress, and uses DNA-SIP technology to identify the phylogenic information of microorganisms that can drive the Sb(V) reduction in the culture system.

  • Patent number: 11044230
    Abstract: A port listening request dynamically generated by an application process hosted in a container can be identified. Whether the application process hosted in the container is trusted can be determined. Responsive to determining that the application process hosted in the container is trusted, a first port to be used as an external port for the application process can be dynamically selected, and a port assignment can be communicated to a container engine, the port assignment indicating the first port is assigned to the application process. The first port can be mapped to a second port assigned as an internal port for the application process. The first port can be opened for the application process.
