A safety portal system for use in existing building, such as schools. The safety portal system includes a first portal section. The first portal section includes a first wall and a second wall, a first open end, a floor portion and a ceiling portion, the at least one open end defined by an outer edge. In addition to the first portal section, the safety portal system includes a second portal section. The second portal section includes a first wall and a second wall, at least one open end, a floor portion and a ceiling portion. The at least one open end of the second portal section is defined by an inner edge that cooperates and engages with the outer edge of the first portal section to create a protective overlap section. A method of installing the safety portal system includes positioning the safety portal system in a desired building and assembling the safety portal system. The safety portal system can then be secured in its desired location within the building.

A multi-threat security apparatus system for critical infrastructure protection is disclosed having an above-ground concrete base, a vertical post system adapted to be attached to the above-ground concrete base and to receive a plurality of louvers. The plurality of louvers provides the necessary ballistic protection for and air flow through to the critical infrastructure. The louvers may include a composite of aluminum foam, a resin impregnated ballistic material and an aluminum foam. The composite structure may be used on doors, panels or building walls.

A flexible insulation material may be configured to substantially reduce the amount of radiation transmitted therethrough by incorporating a reflective mat of high temperature fibers that withstand temperatures of at least 500° C. The flexible insulation may be stored and used over temperatures ranging from −270° C. to 5000° C. The mat may have optical properties to produce a transmittance of no more than 5% over a range of temperature from 500° C. to 5000 vC. The mat may include high temperature fibers such as carbon and/or silicon carbide and these fibers may be coupled by a binder in a non-woven fabric. The flexible insulation material may be configured in the Flexible Thermal Protection System of a deployable aerodynamic decelerator or a Hypersonic Inflatable Aerodynamic Decelerator and may be durably flexible.

A tuned liquid damper, including a first outer housing having two ends, the first end being open to the atmosphere and the second end being connected by a conduit to a gas-filled second outer housing. The conduit may be adapted to allow gas flow between the second end and the second outer housing. The tuned liquid damper may also include first and second membranes, each attached to the inside of the first outer housing, and a sealed compartment within the first outer housing defined by the first and second membranes. The sealed compartment may be at least partially filled with a liquid, which prevents gas flow through the first outer housing from the first end to the second end.

A method for operating a disaster safe smart shelter includes: a step (a) for transmitting, by a transmitter installed in an arbitrary bus, operation data including a plurality of pieces of bus operation-related information; a step (b) for receiving, by the receiver, operation data transmitted from transmitters installed in one or more buses, calculating an entry order of buses to arrive at the disaster safe smart shelter, on the basis of the operation data, and assigning the entry order to each of the n sectors, a step (c) for identifying, by a sensor module installed in each of the n sectors, whether a bus assigned in the step (b) enters, and a step (d) for opening and shutting, by the door control unit, the opening and shutting door of a sector where the entering of the bus is identified in the step (c).

A sunshade device and management system for mitigating the effects of climate change to help reduce the risk of extinction of plants, animals, and humans. The sunshade device has a canopy, which will collapse when lifted into the atmosphere by lifting devices, and open when the lifting devices are turned down or off, to provide shade. The canopy is preferably formed of a flexible lightweight solar panel film containing solar cells, which charge a battery power system which operates electrically powered propeller-driven lifting devices attached to a central portion of the canopy. The sunshade management device controls the lifting devices to manage the sunshade device elevation, angle and geolocation. The sunshade management device is provided with artificial intelligence and machine learning whereby it is able to make determinations regarding sunshade device takeoff and shutdown, and positioning of the elevation and angle of the canopy relative to the ground below, to maximize the shade effects of the canopy.
