Abstract: A bracket includes a first wing, a second wing and a bridge that connects the first wing to the second wing. The first wing has a first inner surface and a first outer surface. The second wing has a second inner surface and a second outer surface. The bridge extends from the first inner surface to the second inner surface thereby coupling the first wing to the second wing such that the first inner surface is normal to a first direction, and the first inner surface is parallel to the second inner surface. The bridge includes a front edge and a rear edge. The front edge forms a recess that extends into the bridge towards the rear edge along a second direction that is perpendicular to the first direction, and the recess terminates within the bridge prior to reaching the rear edge.

Abstract: A connector includes a first joint member, a second joint member, and a fastener. The first joint member includes a first tubular outer wall at least partially enclosing a first outer cavity, and a first tubular inner wall at least partially enclosing a first inner cavity. The second joint member includes a second tubular outer wall at least partially enclosing a second outer cavity, and a second tubular inner wall at least partially enclosing a second inner cavity. The fastener extends through first and second openings of the first inner cavity, and through first and second openings of the second inner cavity to position the first joint member relative to the second joint member.

Abstract: Systems and methods for modular dwelling units that may be combined into a modular building. The modular dwelling units may be fluidly isolated from each other by a sealing system that prevents fluids from leaking into adjacent modular dwelling units, and a subfloor system that is tilted to drain fluids towards a conduit that leads away from the modular building. The modular dwelling units may include one or more sensors that generate signals based upon conditions within the modular dwelling unit and/or based on occupants of the modular dwelling unit. The modular dwelling units may include one or more processor-based devices that may generate an alarm and/or control one or more actuators or valves in response to the signals received from the sensors.
