Abstract: A system and method are disclosed for lowering the internal relative humidity inside of a concrete structure by applying a pressurized gas and forcing such pressurized gas into the concrete structure, in turn driving moisture in the pores of the concrete to the exterior of the structure. Pressurized gas is supplied to a network of sealed cavities extending into the face of the concrete structure, ultimately causing the gas to move into the concrete structure through pores and capillaries through the structure, in turn driving moisture in the concrete structure toward the surface. Optionally, a competitive inhibiting agent, such as lithium nitrate, may also be provided to stabilize the concrete structure against future deleterious expansions caused by moisture uptake in the existing ASR gel.

Abstract: A method and computer program product are provided for controlling the airflow direction through a device enclosure. A first device enclosure is positioned adjacent a second device enclosure, wherein both enclosures have an airflow pathway extending from the front to the back, and a fan for moving air through the airflow pathway, wherein the fan of the first device enclosure is a reversible rotary fan. The method automatically determines whether the first device enclosure is in a first orientation with its front facing in the same direction as the front of the adjacent second device enclosure or in a second orientation with the front facing in the same direction as the back of the adjacent second device enclosure. The airflow direction imparted by a reversible rotary fan is then controlled according to the determined orientation of the first device enclosure relative to the second device enclosure.

Abstract: Systems and methods for intelligently alerting the flight crew of a cabin depressurization. An example system includes a cabin altimeter that generates a cabin pressure value, an alerting device, such as a speaker system and a processing device in data communication with the cabin altimeter and the alerting device. The processing device determines if there is a problem with the cabin pressure received from the cabin altimeter, determines rate of change of the cabin pressure, and sets at least one of an alert volume or an alert frequency based on the cabin pressure and the rate of change of the cabin pressure if it was determined that a problem exists with the cabin pressure. The processing device also issues a cabin depressurization alert over the alerting device based on at least one of the set alert volume or alert frequency, if there is a problem with the cabin pressure value.
