Abstract: An air distribution panel for aircraft comprises a primary air inlet port, a housing fluidly coupled to the primary air inlet port, and an environmental sensor. The primary air inlet port is configured to be fluidly coupled to and receive primary air from an air distribution plenum. The housing comprises an air outlet chamber and a secondary air inlet chamber. The primary air is exhausted into an aircraft compartment via the air outlet chamber. Secondary air is drawn from the aircraft compartment via the secondary air inlet chamber. Exhausting of the primary air through the air outlet chamber causes the secondary air to be passively drawn into the secondary air inlet chamber. The environmental sensor is positioned within the secondary air inlet chamber and along an airflow path of the secondary air. The secondary air is exhausted via the air outlet chamber back into the aircraft compartment after the secondary air passes the temperature sensor.

Abstract: An ergonomic casing and tool holder (ECTH) primarily for use in reloading of firearm ammunition and hand-held tool holding. This holder can secure casings frontwards or backwards. The wide clamping range of various collets/chucks allow for holding any variety of casings or tools. The protrusion of casings or tools is set by various adjustable backstops. The design allows a reduced clamping load for collapsing commercially available double angle collets.

Abstract: Disclosed are a fluid control system and method for controlling delivery of two variable pressure fluids to maintain a pressure bias between the two fluids within an end use device. The system employs an actively controlled vent valve which can be integrated into a fluid control module in preferred embodiments and is actuated to an open position to decrease fluid pressure in a first fluid supply line when a determined pressure differential reversal exceeds a predetermined threshold pressure differential reversal. The disclosed system is particularly useful in a high pressure direct injection (HPDI) multi-fueled engine system where the first fluid is a gaseous fuel and the second fluid is a liquid fuel. The fluid control system and method of controlling it provide for improved control of venting along with protecting system components from high back pressure and cross contamination of fluids.

Abstract: Tiles having a matrix of interconnected vaults on its underside surface provides space for flow of heated or conditioned air, passages for electrical service conduits and wiring, or passages for drainage. In particular, each tile may comprise a solid rigid body having a substantially planar upper surface and thickness substantially less than upper surface linear dimensions. The underside surface has a set of concavities forming a matrix of vaults bounded and interconnected by archways. Each archway is characterized by a rise dimension that is less than a span dimension. The matrix of vaults defines a set of pendentives at each vault corner whose load-bearing bases are all substantially coplanar with one another so as to contact a supporting subfloor. Edges of the tile body have corresponding alternating laterally projecting extensions and indentations for forming (with some desired leeway) mortise-and-tenon joints between adjacent tiles.
