Abstract: The present invention relates an integrated, post-tensioned building construction system that utilizes a rectangular array of interlocking block components for the shell of building structures. Internal tendons that pass through the interlocking blocks are affixed to beams at the base or foundation of the building walls and terminate above beams atop the building walls. The ends of tendons receive mechanical fasteners that are tightened to the beams and/or foundation. The tendons serve to maintain the integrity of the interlocking block components, which cannot come apart when the tendons are tightened. Build stops secured to tendons help to stabilize the interlocking block components during construction. With interlocking blocks fabricated from a compressible material, like concrete-and-aggregate, the tendons are tensioned to induce a compressive load on the material.

Abstract: The present invention relates to a portable, self-contained, neonatal intensive care unit (NICU) providing heating (or cooling) for the patient by controlled exchange of thermal energy between a transparent enclosure that houses the infant and an internal reservoir. The invention has no requirement for electrical power. The internal reservoir utilizes water that is heated (or cooled) by an external source. The micro-environment inside the transparent enclosure for the infant and the water inside the internal reservoir are thermally and acoustically isolated in order to minimize heat and sound exchange with the ambient environment.
