Abstract: A system for restricting access to an area includes a security barrier with a security hood. The security hood includes a body having a plurality of openings, a plurality of lights positioned within the plurality of openings, a control module and a communications system. The lights may be recessed into the body. The control module changes the security hood between an inactive state and an active state. The control module controls the plurality of lights. The communications system receives data from a remote command location and provides the data to the control module. The data includes instructions for altering operation of the security hood. The communications system may include a satellite link.

Abstract: An artificial stone building tile and method. Disclosed is an artificial stone building tile and a method of making the building tile. The building tile has a low density and significant flexibility, and is nailable without cracking. It is made by layers of cement formulations separated by layers of metal mesh. Color batches of cement are prepared and placed in the bottom of a mold, with the color batches becoming the visible face of the building tile.

Abstract: A method of restricting access to an area comprises removing a plug from a receptacle in a ground region and positioning a base of a security barrier into the receptacle after the removing the plug. The receptacle extends downward from a surface of the ground region. The security barrier includes a tower extending upward from the base. The security barrier restricts movement of vehicles across the ground region when the base is received within the receptacle and the plug does not restrict movement of vehicles across the ground region when the plug is received within the receptacle. The plug has a first shape and the base of the security barrier has a second shape corresponding to the first shape of the plug. The first shape and the second shape are interchangeably receivable within the receptacle for selectively restricting movement across the ground region.
