  • Publication number: 20240140619
    Abstract: The present invention discloses a method for autonomous mission planning of Carbon Satellite, which triggers autonomous mission planning for the satellite when it detects the satellite switching from a shadow area to a light area, comprising: determining planning time sequence, wherein the planning time sequence comprise several time nodes; and then, for each time node, carrying out a prediction of the ground attributes of the sub-satellite point, and setting observation arc segment according to the prediction result; and finally, determining the load power-on-off time sequence according to the observation arc segment.

  • Publication number: 20240131477
    Abstract: Hydroxide-exchange membranes (HEMs) and hydroxide-exchange ionomers (HEIs) are provided which include polymers with oxidation resistant groups. The attachment of the oxidation resistant groups to the polymer backbone allows fine-tuning of the mechanical properties of the membrane and incorporation of alkaline stable cations, such as imidazoliums, phosphoniums and ammoniums, and provides enhanced stability to the polymer. HEMs/HEIs formed from these polymers exhibit superior chemical stability, anion conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties in an ambient dry state as compared to conventional HEM/HEIs. The HEMs exhibit enhanced stability in a highly oxidative environment.

  • Patent number: 10629973
    Abstract: A phase shift device includes a planar transmission line that is formed by a signal electrode and a ground electrode which are separated by a dielectric substance, whereby the signal electrode of the planar transmission line is divided into several pieces and includes overlapping areas of adjacent pieces that are filled with a tunable liquid crystal material, thereby forming a dielectric tunable component (varactor) with a metal-insulator-metal type capacitor. The several pieces of the signal electrode are arranged at two or more different distance levels with respect to the ground electrode. The tunable liquid crystal material is arranged as a continuous layer between several pieces of the signal electrode that are arranged at two different distance levels.
