  • Patent number: 10680154
    Abstract: In a known method in which a cooling pipe that is fixed and rigid is used, variation in a distance from the center of an exhaust heat pipe to the outer surface of a thermoelectric conversion module, variation in the radius of curvature of the curved surface of a cooling pipe, and other factors produce a gap between the outer surface of the thermoelectric conversion module and the inside surface of the cooling pipe. The gap prevents the achievement of desired cooling performance and the improvement of power generation efficiency. A thermoelectric conversion module of the present invention includes two flexible substrates each made of a thin resin film and having mounting lands formed thereon, and a plurality of thermoelectric elements mounted on the mounting lands at high density, wherein one of the two flexible substrate has a plurality of slits to make the module easy to bend.

  • Patent number: 10622937
    Abstract: Photovoltaic modules are mounted onto a solar tracker array torque tube via pairs or left-handed and right-handed photovoltaic array connectors having spring latch assemblies.

  • Patent number: 10164135
    Abstract: Certain example embodiments of this invention relate to the use of graphene as a transparent conductive coating (TCC). In certain example embodiments, graphene thin films grown on large areas hetero-epitaxially, e.g., on a catalyst thin film, from a hydrocarbon gas (such as, for example, C2H2, CH4, or the like). The graphene thin films of certain example embodiments may be doped or undoped. In certain example embodiments, graphene thin films, once formed, may be lifted off of their carrier substrates and transferred to receiving substrates, e.g., for inclusion in an intermediate or final product. Graphene grown, lifted, and transferred in this way may exhibit low sheet resistances (e.g., less than 150 ohms/square and lower when doped) and high transmission values (e.g., at least in the visible and infrared spectra).
