  • Publication number: 20260168232
    Abstract: Disclosed is an example of a movable workspace configured to operate in a harsh environment. The exemplary movable workspace includes a primary compartment and a deployable expansion compartment. The primary compartment may have a primary workspace, and at least one primary connection point adapted to releasably secure work equipment within the primary workspace. The deployable expansion compartment may have an expansion workspace, and at least one expansion connection point adapted to secure the work equipment within the expansion workspace. The movable workspace may include a movement component to facilitate movement of the movable workspace either on its own or with assistance from a transport vehicle. The movable workspace is configured to be transported in a transport state in which the expansion workspace meshes with the primary workspace. Upon delivery at a work site, the expansion workspace extends from the primary workspace to place the movable workspace in a work state.

  • Patent number: 9068283
    Abstract: In one aspect, the present invention relates to a layered structure usable in a strain sensor. In one embodiment, the layered structure has a substrate with a first surface and an opposite, second surface defining a body portion therebetween; and a film of carbon nanotubes deposited on the first surface of the substrate, wherein the film of carbon nanotubes is conductive and characterized with an electrical resistance. In one embodiment, the carbon nanotubes are aligned in a preferential direction. In one embodiment, the carbon nanotubes are formed in a yarn such that any mechanical stress increases their electrical response. In one embodiment, the carbon nanotubes are incorporated into a polymeric scaffold that is attached to the surface of the substrate. In one embodiment, the surfaces of the carbon nanotubes are functionalized such that its electrical conductivity is increased.
