Abstract: A wind-articulated, warning sign system responsive to oblique wind currents acting external to surfaces of its exposed, non-flat-sheet and non-fabric structural elements and which provides a functional-airfoil-cross-section with surface configured to display and provide emergency critical technical data for specific classes of regular and emergency visitors to the entrance portal of an industrial site where large quantities of dangerous substances, including, radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating, biohazardous, toxic, pathogenic, or allergenic substances are handled and which substances might be released by accident or by terrorist attack and dispersed by winds into the local environment.

Abstract: An integrated security system for oil-field and gas-field sites is disclosed. The system utilizes state-of-the-art technologies including “logical QR emblems” and powerful, advanced RFID tags. The system is particularly valuable for emergency responders, since it facilitates immediate, secure display of critical site data-according to predetermined classifications, e.g., emergency triage for an accident or terrorist event.

Abstract: A warning sign for use at a site where the risk of hazardous materials is present such as hydrocarbon wells and processing equipment wherein the sign provide satisfying indicia and indicates wind direction and intensity allowing for a soft approach to the site from an upwind position.

Abstract: A modular magnetic card read/write apparatus for installation in an associated mechanism is constructed from modular read/write assemblies. The module construction allows for assembly of different length card read/writers by adding additional modules to fit longer or shorter card paths imposed by the particular application and the associated mechanism. Modular read/write assemblies further provide the option of multiple head readers at various positions to allow reading of more than one card track without modification to the apparatus.
