Abstract: An entry system includes a plurality of first user devices, such as key fobs, ID cards and the like. A plurality of second user devices are maintained by users, and may include mobile phones, smart watches and tablets. A main entry system controls a barrier to allow entry to approved individuals. An authorization system is configured to validate the first and second user devices, and to send an electronic questionnaire to the second user device. The user must complete the questionnaire and transmit it to the main entry system. The second user device, the main entry system, and the authorization system communicate with each other over a computer network. If the user successfully completes the questionnaire and the user's identity is authenticated, the main entry system allows the barrier to be opened so that the user may enter the facility.

Abstract: A door assembly includes a doorframe, an insulated glazing unit (IGU), door skins, and a gas passageway. The IGU includes a substantially sealed IGU cavity and a hole communicating with the IGU cavity. The door skins are secured to opposite sides of the doorframe and have openings between which the IGU is provided. The gas passageway provides gas communication between the IGU cavity and the atmosphere outside of the door assembly. The gas passageway contains a gas passage conduit that includes a first end communicating with the IGU cavity through the hole and a second end communicating with atmosphere outside of the door assembly. The gas passageway may contain a gas passage conduit having a first end communicating with the IGU cavity through the first hole and a second end communicating with an air pocket, and a channel connects the air pocket with atmosphere outside of the door assembly.

Abstract: A door is provided that includes a door panel having a periphery and opposite first and second panel surfaces, stiles and rails collectively surrounding the panel, and sealant. The stiles have channeled stile surfaces extending across a thickness of the stiles and facing one another. The rails have channeled rail surfaces extending across a thickness of the rails and facing one another. The channeled stile surfaces and the channeled rail surfaces include channels with open ends that receive the periphery of the panel, first grooves positioned at first interfaces of the first panel surface and first edges of the open ends of the channels, and second grooves positioned at second interfaces of the second panel surface and second edges of the open ends of the channels. The sealant is received in the first and second grooves, preferably forming a water-proof seal.

Abstract: The present invention provides a pre-hung door assembly containing a door slab hung inside a door frame. The margins (space between the perimeter of the door and the frame) between the door slab and the door frame are maintained using at least one door jamb margin holder, at least one door lock margin holder, at least one bottom margin holder, or combinations of these holders. The margin holders allow the margins to be maintained and prevent unwanted opening of the door during the shipping and transportation of the door assembly. The jambs of door frame may include predrilled holes for securing the door assembly to the door opening. Details for the door jamb margin holder, the door lock margin holder, and the bottom margin; and methods for installation of the door assembly are also provided.
