Abstract: A folding modular structure is described. The structure typically includes a top panel, which is ultimately the roof deck. Two side panels, a front and a rear panel are connected to the top panel by pivoting mechanisms so that the side, front and rear panels can fold open to create the modular structure. Spacer panels are connected between three of the four total side, front and rear panels. The spacer panels are necessary to provide clearance so that each of the panels can be folded onto the other already folded panels. In the folded configuration, shipping many more modular structures to final destinations is possible.

Abstract: A method and apparatus for constructing hollow metal frames having a grout filled interior is disclosed. An apparatus includes a substantially planar body having an upper and lower surface. The upper surface includes at least one grip. The lower surface includes a gasket and a number of protrusions. The protrusions are placed into holes on the hollow metal frame into which additional components such as hinges are to be added. Grout is added to the frame and allowed to harden. Once the grout is hardened, the grout guard is removed and air spaces are retained. Screws and other components are typically filled into the air spaces.

Abstract: A self-latching slide door apparatus for food/cuff passes on prison doors is disclosed. The apparatus includes a main body connected to a front panel. The front panel includes slide doors that cover an aperture in the front panel when in a closed state. The slide doors have self-latching devices that lock the doors when in the closed position, therefore requiring no additional locks.

Abstract: A non-contact food/cuff pass apparatus and system is disclosed. The apparatus generally includes a hollow body adapted to be affixed to a prison door aperture. The hollow body includes a door on one end. The other end is open to be affixed to the prison door aperture. A locking lever is connected to the main body. The locking lever is adapted to lock the body to the prison door. The interior of the body is used to place items to be passed to and from a prisoner.

Abstract: A method and apparatus for inputting design specifications to calculate output specifications and manufacturing machine code is disclosed. A user interface simplifies the data input by a user to calculate the necessary manufacturing specifications. The user interface is typically connected to a computer aided design (CAD) process. The CAD process in turn processes the design input specifications entered by the user.
