This disclosure involves a method of controlling a safety critical control device, the method comprising: sending user inputs to a first state machine, identifying user inputs by the first state machine, determining the correct state to communicate to a second state machine, the correct state being determined by selecting one state of a plurality of states depending on the user inputs, communicating the correct state to a second state machine through a control bus, and determining the correct state for the second state machine based on communication from the control bus.

A concrete layer having an upper surface and a lower surface, a first fiber layer having longitudinally oriented and radially oriented fiber embedded in the upper surface of the concrete layer, and a second fiber layering having longitudinally oriented and radially oriented fiber embedded in the lower surface of the concrete layer.

A cementitious composition may include polyvinyl alcohol, high alumina cement, water, a metallic coagent, a peroxide crosslinking initiator, and an organic acid retardant. A molded article may be manufactured from the cementitious composition by preparing a hydrogel pre-polymer blend of saponified polyvinyl alcohol acetate (PVAA) with greater than or equal to approximately 85% saponified PVAA, and water, mixing the hydrogel pre-polymer blend with high alumina cement (HAC) using a high shear mixing process, mixing in a metallic coagent and a peroxide crosslinking initiator, mixing in an organic acid retardant, and hot press molding the mixture.

A lightweight foamed polymer concrete admixture for use in fabricating building components, the polymer concrete comprising a mixture of a polyol, an isocyanate, an aggregate, and water, wherein once mixed, the mixture releases carbon dioxide gas creating a foamed mixture that may be shaped to form a building component such as, but not limited to, lap siding, shake siding, trim boards, stone and stucco sheeting.

The present disclosure is related to a system for manufacturing an article. The system includes a first mold half and a second mold half. The first mold half and the second mold half define a molding cavity therebetween. The molding cavity is configured to receive two outer layers and a high viscosity material provided between the two outer layers. The system also includes an actuator configured to move at least one of the first mold half and the second mold half towards the other. The first mold half and the second mold half are configured to deform the high viscosity material in conformation with a shape of the article. The high viscosity material fills a space between the two outer layers such that the two outer layers encase the high viscosity material therebetween.
