Abstract: The present disclosure is directed to a modular dwelling constructed from intermodal containers. Particularly, the present disclosure is directed to a dwelling constructed from vertically oriented shipping containers. The dwelling may include a foundation and two or more intermodal containers disposed on and secured to the foundation. The intermodal containers may be separated by an interstitial space. The interstitial space may be fully or partially enclosed by a plurality of connector walls. Each intermodal container includes a top, a bottom, and four side walls One of the side walls may be a reinforced side wall. The reinforced side wall of one of the intermodal containers may extend parallel or perpendicular to one or more of the reinforced side walls of other intermodal containers. The dwelling may be divided into one or more rooms, floors, or apartments and may have doors, windows, appliances, a deck, or other common features.

Abstract: The present invention relates to systems that utilize a combination of immunoassay and magnetic immunoassay techniques to detect an analyte within an extended range of specified concentrations. In particular, a device is provided for detecting an analyte in a biological sample. The device includes a first electrochemical sensor positioned on a substrate. The first electrochemical sensor includes an immobilized layer of antibody configured to bind to the analyte. The device further includes a second electrochemical sensor positioned adjacent to the first electrochemical sensor on the substrate, and a magnetic material that generates a magnetic field aligned with respect to the second electrochemical sensor. The magnetic field captures magnetic beads that have an immobilized layer of antibody configured to bind to the analyte, and concentrates the magnetic beads on or near a surface of the second electrochemical sensor.
