    Abstract: A power supply comprises a DC power source, first and second DC/DC converters, and a protection circuit. The DC power source provides DC power at a variable bulk voltage. The first DC/DC converter converts the DC power from the DC power source to DC power at a high voltage suitable for powering a high-voltage load. The second DC/DC converter receives DC power from the first DC/DC converter, converts the received DC power to DC power at a low voltage, and delivers the DC power at the low voltage to a low-voltage load. The protection circuit selectively transfers DC power from the first DC/DC converter to the high-voltage load. The DC power source may be an AC/DC converter receiving AC power from a power generator driven by an aircraft engine.

    Abstract: A two-stroke internal combustion engine has a crankshaft disposed at least in part in a crankcase, and a cylinder block connected to the crankcase and defining a cylinder.The cylinder defines at least one exhaust port for discharging exhaust fluid. A piston is movably disposed within the cylinder and is operatively connected to the crankshaft. The piston is movable along a cylinder axis in a reciprocating motion including an upstroke and a downstroke. An exhaust valve assembly is operatively connected to and rotates with the crankshaft. The exhaust valve assembly has a shaft rotatably supported by the cylinder block and a valve configured to cyclically obstruct the exhaust port. The valve is operable to move clear of the exhaust port before the piston uncovers the exhaust port during its downstroke, and at least partially close the exhaust port before the piston fully covers the exhaust port during its upstroke.

    Abstract: A tunnel for mounting above a road surface (3) comprises a plurality of tunnel segments (1). Each tunnel segment is adapted for mounting at least one projector (6) therein, above a respective opening formed by the tunnel segment in a ceiling of the tunnel. The openings (5) of the plurality of tunnel segments are spaced apart in succession in a direction of travel of vehicles in the tunnel. The tunnel segments are disposed such that projection surfaces (8) of the projectors are seamlessly contiguous or overlapping on the road surface in the direction of travel. The tunnel may comprise awnings positioned at its entrance and its exit, the ceiling being formed at least in part by the awnings. A first awning (10A) may be mounted to a first tunnel segment, in the direction of travel, and a second awning (10B) may be mounted to a last tunnel segment, in the direction of travel.

    Abstract: A valve for use in an engine exhaust conduit. The valve includes a base portion and a body portion extending from the base portion. The base portion is configured for pivotably mounting the valve within the engine exhaust conduit. The base portion definesa valve pivot axis. The valve ispivotable about the valve pivot axis during use. The body portion hasan upstream side and a downstream side opposite the upstream side.The upstream sideis exposed, during use, tofluid flow in the engine exhaust conduit. The body portion hasa generally pointed shape defining a rounded tip at a location of the body portion furthest from the base portion in a length direction of the valve.The length direction of the valve is generally perpendicular to the valve pivot axis.
