A composite construction element or panel system for use in construction of multi-storey structures, either as a prefabricated panelized system or as a modular system. The composite construction element comprises two mass timber subpanels joined at a distance to form a hollow core, through which various building services (e.g. HVAC or electrical systems) and/or insulation may be integrated. When used as a modular system, after assembly, the two subpanels become one structural entity of increased structural capacity while providing a hollow core to provide/deliver desired building services.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

An amusement system features an interactive floor with an array of panels laid out in one or more grids to collectively define an interactive floor surface, an illumination system operable to individually illuminate each panel, and a sensing system operable to detect presence of any participant atop any panel. A base frame of the interactive floor is composed of a plurality of base modules seated on a subfloor, and supporting a respective panel for one or more cells of the interactive floor. The base modules are not directly fastened together, and instead are only intercoupled by perimeter seals applied over peripheral regions of the panels of neighbouring modules. Separation of the modules is constrained by surrounding walls of a room fully occupied by the interactive floor. In gameplay, some panels are distinctively illuminated as hazards to be avoided by participants, subject to penalty.

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.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

A device for heating a room (2) in a building by means of underfloor heating, the floor comprising pipe loops (4) for circulation of a hot medium, preferably water. The floor has a subfloor (1) and an upper floor (8) at a mutual distance, so that an air-filled chamber (16) is formed between them. In the outer wall (3) of the room there are inlet openings (7) for fresh air, which by means of negative pressure ventilation in the room (2) flows into the chamber (16), over the pipe loops (4) to heat up, and out through outlet openings (9) in the upper floor (8). The heat absorbed from the pipe loops (4) goes partly up through the upper floor (8), partly out into the room (2) as heated air. The pipe loops (4) extend transversely of the direction of movement of the air from the inlet (7) to the outlet (9) and are partly cast in concrete on the bottom of the chamber (16).
