The present relates to a device being used in modular building construction comprising at least one flat load support comprising a first main face and a second main face, at least one elongated load support designed for being coupled with said flat load support. The device is characterized in that said flat load support comprises an array of transverse openings extending through the thickness of the flat load support. The flat load support is arranged for fastening said flat load support with said elongated load support at any position corresponding to one of said opening in a reversible manner and to any position between said openings in a reversible manner. Each flat load support comprises reversible lateral connection means and/or reversible transversal connection means for coupling flat load supports in a reversible manner. The flat load support and the elongated load support are arranged for being detachably assembled to provide the modular, reversible, and/or versatile building construction. The invention further relates to a modular construction building based on said device and to a method using said device.

A module mat system with first layer that is joined to a second layer by fusion welding, hot welding, hand welding, seam welding, heat pressing, or other methods know to those having skill in the art. Each layer has a central core with a first cellular structure formed from ribs extending from the interior surface. The cross section of the ribs in the central core of the first layer matches the cross section of the ribs in the central core of the second layer such that when fusion welded together the ribs of the central core of the first layer weld to the ribs of the central core of the second layer.

A gait assistance slab is provided. The gait assistance slab includes a body that includes an outer surface. The gait assistance slab further includes a plurality of sensors disposed inside the body. The gait assistance slab further includes a plurality of actuators disposed inside the body. The gait assistance slab further includes circuitry communicatively coupled to the plurality of sensors and the plurality of actuators. The circuitry detects a presence of a person on the outer surface based on an electric signal acquired from one of the plurality of sensors. The circuitry determines a level of actuation of one of the plurality of actuators based on the detected presence of the person and the acquired electric signal. The circuitry further controls, based on the determined level of actuation, the one of the plurality of actuators to assist gait of the person on the outer surface.
