  • Patent number: 11927921
    Abstract: The main element 2 is connected to the mechanism of the movement, having parts 4, 5, by an arbor about which it can turn. To this end, it comprises an attachment 6 for fixing to the movement, which is for example formed by a small ring arranged in the opening 9 of the ring of the main element 2. The attachment 6 is thus composed of the same material as the main element and is arranged in the same plane. By virtue of the attachment 6, the winding mass can make a circular movement about the arbor, when it oscillates.

    Abstract: Proposed is a method of preparing an independent free-standing graphene film. The graphene film is obtained by means of suction filtration of graphene oxide into a film, solid phase transfer, chemical reduction and the like steps. The graphene film is formed by means of physical cross-linking of a single layer of oxidized/reduced graphene oxide. The graphene film has a thickness of 10-2000 atomic layers. The graphene oxide film has a small thickness and a large number of defects inside, so that it has good transparency and excellent flexibility. On the basis of the transfer film-forming method above, an independent free-standing wrinkled graphene film having a nanoscale thickness is prepared by using a poor solvent and a special high temperature annealing process, and an independent free-standing foamed graphene film having a nanoscale thickness is obtained by using a film-forming thickness and a special high temperature annealing process.

  • Patent number: 9908640
    Abstract: Systems, methods, and apparatus for space surveillance are disclosed herein. In one or more embodiments, the disclosed method involves scanning, by at least one sensor on at least one satellite in inclined super-geostationary earth orbit (super-GEO), a raster scan over a field of regard (FOR). In one or more embodiments, the scanning is at a variable rate, which is dependent upon a target dwell time for detecting a target of interest. In at least one embodiment, the target dwell time is a function of a range from at least one sensor to the target of interest and a function of a solar phase angle. In some embodiments, the axis of inclination of the inclined super-GEO is a function of the solar phase angle.
