    摘要： Embodiments of the present invention relate to electromagnetic interference (EMI) shielding structures. Rectangular EMI shielding panels are formed that include a first and second ends. A pair of rectangular EMI shielding panels are affixed orthogonal to each other at their first ends. The pair of rectangular EMI shielding panels are successively overlapped with each other to thereby form a plurality of interconnected EMI shielding planes. The pair of rectangular EMI shielding panels are affixed to each other at their second ends to form a helical EMI shielding structure that unfolds to an unfolded state and folds to a folded state along its center axis. Here, the plurality of interconnected EMI shielding planes are each angularly offset from each other about the center axis to form a helical structure when in the unfolded state. The EMI shielding panels include an encapsulating layer and/or metallic layer.

    摘要： An article includes a first layer comprising a substrate having one or more images applied thereto. A second layer applied on each image and comprising one or more first and second portions, the first portion and second portions each in communication with a first image area and a second image area of an image, respectively. The second layer comprises a coating composition comprising fully exfoliated single sheets of graphene. The first and second portions comprise first and second detectable properties, respectively, having a value correlated with the graphene. The first and/or second detectable properties each comprise a first X-ray diffraction pattern, a first electrical conductivity, and one or more of a thermal conductivity, an optical property. The first and second detectable properties together create a distinctive signature for the article.

    摘要： Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders may employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system can establish mesh networking communications and communicatively couple to portable radios via a communications device. Some of the antenna elements may be within the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end that couples to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps may include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements may be formed using a conductive composition that includes fully exfoliated graphene sheets present as a percolated network in a polymer matrix.

    摘要： Embodiments of the present invention relate to communications tarpaulins. In one embodiment, the communications tarpaulins include a textile layer, a plurality of antenna elements, and a communications hub. The communications hub includes a plurality of radio frequency (“RF”) connectors. The communications hub is affixed to the textile layer. The RF connectors are each conductively coupled to one of the antenna elements. The RF connectors each demountably receive a communications device. The antenna elements are each affixed to the textile layer and includes a conductive composition. The antenna elements each include a conductive composition. The conductive composition includes a polymer and fully exfoliated single sheets of graphene that are present as a three-dimensional percolated network within the polymer. The textile layer includes a first textile layer and a second textile layer that are coterminous and physically coupled together and thereby form a multilayered structure.

    摘要： Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system communicatively couples to portable radios that operate on different RF frequencies via a communications hub. Some of the antennas elements are dynamically positionable (i.e., swappable, switchable, etc.) on the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end. The demountable fasteners couple to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements are formed using a conductive composition of fully exfoliated graphene sheets present as a percolated network in a polymer matrix.
