Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. In structures, be they land-based, offshore or even ships, the owners and operators are responsible to maintain their facilities in accordance with a design-basis that is rooted in laws, including the local building code and fire code, which are enforced by the Authority Having Jurisdiction.

A method of continuously forming a multilayer panel includes making a gypsum slurry, then dividing the gypsum slurry into at least a primary gypsum slurry and a secondary gypsum slurry. An additive slurry having water and an intumescent material is created, then added to the secondary gypsum slurry to make an expandable layer slurry that is spread over at least a portion of a facing material. The primary gypsum slurry is distributed over the secondary gypsum slurry over the facing material and the expanding layer slurry to form a core. Optionally, another layer, an edge coating, is applied to the expanding layer for additional fire protection. The edge coating includes a second intumescent material. During a fire, the expanding layer expands to increase the thickness of the fire exposed gypsum panel and the edge coating expands to seal the gap between adjoining gypsum panels.

The present invention is a method and apparatus that provides detection, characterization, and intuitive dissemination of targets. This disclosure combines improvements to ultra-wideband (UWB) sensing and machine target characterization with a means to convey data in a format that is quickly and readily understood by practitioners of the technology. The invention is well suited for Situational Awareness (SA) support in areas that are occluded by rain, fog, dust, darkness, distance, foliage, building walls, and any material that can be penetrated by ultra-wideband RF signals. Sense Through The Wall (STTW) performance parameters including target range, stand-off distance, and probability of detection are improved herein by combining a dynamically positioned sliding windowing function with orthogonal feature vectors that include but are not limited to time amplitude decay, spectral composition, and propagation time position in the return signal data. This invention is particularly useful for STTW and SA applications including urban combat, law enforcement, fire protection, transportation security, and homeland security. The invention can also be used to detect objects that are concealed by clothing, debris, and other non-metallic materials.
