Pre-fabricated wall panels with embedded electronic devices. Also, a modular building made from pre-fabricated panels with embedded electronic devices, individual panel identifiers, and a central computer system.

A portable modular shelter apparatus comprises a base, a roof, a plurality of wall elements, a plurality of corner elements, a photovoltaic solar collector, electrical circuit componentry and a utility panel. The base defines a storage compartment. The apparatus is configurable from a disassembled transport condition into an assembled condition, in which the base, roof, walls and corners are configured to releasably interlock to form a rigid shelter having a solar powered electricity supply circuit.

A temporary wall system providing wall panels with peripheral surface mounted roto-locks for linear combinations is provided. Hinged corner posts also, providing the roto-locks, enable selectively orienting wall panels transversely relative to each other. Each wall panel provides an internal strut structure for strengthening the wall panels.

An enclosure for use as a walk-in freezer or refrigerator includes a first panel and a second panel connected to the first panel. Each of the first and second panels includes a body having a frame coupled to the body. The frame includes a beam of a first material and a jacket of a second material at least partially enclosing the beam. An interior edge of the frame is adjacent to the body. An exterior edge is defined by the jacket and defines a joint member. The joint member of the first panel defines a groove, and the joint member of the second panel defines a protrusion adapted to engage the groove of the joint member of the first panel. At least one joint member includes a deformable portion that compresses when the joint member of the first panel engages with the joint member of the second panel.

A field-deployable construction set for the assembly of a Relocatable Habitat Unit (RHU) and associated panels, used for simulating real world environments without costly construction expenses. The various panels, supports, and accessories used to construct an RHU may be interchangeable and readily modified in the field with minimal tools, further providing significant options for reconfiguration of floor, ceiling, and wall panels without having to disassemble the structure. The exterior of the lightweight panels may be customizable to provide a realistic environment for high quality training in a versatile system that is deployable by truck or aircraft and can be assembled with only a single tool. The RHU or components thereof may simulate a real building structure both visually and in a non-visual domain such as via electromagnetic sensors.

Means for releasably connecting two constructional panels to one another comprising first and second parts, wherein: the first part has a bolt; and the second part has an enclosure with an opening into which the bolt of the first part can be moved, a cam rotatable about a pivot within an enclosure between an open position and a locked position, the cam having a slot formed within it adapted to receive a portion of a corresponding bolt of the first part, the slot having a bolt engagement surface with a portion sloped at an angle to the said second dimension, the slot having a locking surface substantially opposite the bolt engagement surface.

A refrigerator having detachably adjacent cabinets is provided. The refrigerator includes a connection mechanism interposed between cabinets adjacent to each other and connecting the cabinets to each other and a manipulation portion configured to drive the connection mechanism by being manipulated from outside, wherein the connection mechanism is configured for the cabinet on one side is pulled toward the cabinet on the other side by a manipulation of the manipulation portion.

A method of manufacturing a kit for a cold storage room includes the following steps: determining one or more dimensions of the cold storage room; providing continuously manufactured insulation panels, cut to have a length based on the dimensions of the cold storage room, and having alignment structures formed thereon; cutting one or more of the continuously manufactured insulation panels to have a width based on the dimensions of the cold storage room and to form one or more joints; forming connecting structures on one or more of the continuously manufactured insulation panels, the connecting structures configured to form one or more joints; and providing connection hardware configured to mate with the connecting structures and to form one or more joints.

A field-deployable construction set for the assembly of a Relocatable Habitat Unit (RHU), used for simulating real world environments without costly construction expenses. The various panels, supports, and accessories used to construct an RHU include male (M) and female (F) lock connectors located on their respective peripheries and a frame constructed from a plurality vertical corner posts and horizontal beams provide the user with innumerable options for floor plans and building design, further providing significant options for reconfiguration of floor, ceiling, and wall panels without having to disassemble the structure. The exterior composition of the expanded polymer foam is customizable to provide a realistic environment for high quality training in a versatile system that is deployable by truck or aircraft and can be assembled with only a single tool.

A fastening system for joining two structural members is provided. The fastening system includes a latching device comprising a housing, at least one eccentric rotatable part and a generally S shaped latch spring hook joined to the rotatable part, and a receiver having at least one hole configured to receive a free end of the latch spring hook. In one embodiment, the bottom portion of the housing is generally semi-circular in shape and the receiver includes two semi-circular frames having a corresponding radius to receive the lower portion of the housing. The latching device is fixed to a first structural member and the receiver is fixed to a second structural member. The structural members may be joined by positioning an end of the first structural member adjacent to the receiver of the second structural member and rotating the rotatable part to cause the free end of the latch spring hook to engage the hole in the receiver. Further rotation of the eccentric rotatable part causes the latch spring hook to exert a pulling force, thereby joining the structural members together. The semi-circular lower portion of the housing and the semi-circular frames on the receiver allows the structural members to be attached at any desired angle using one fastening system.
