A skirt panel is provided herein for interconnection to another abutted similar skirt panel for attachment beneath a lower, outer longitudinally-extending edge of a trailer including a rear wheel assembly of a tractor-trailer rig, thereby to provide a continuous fairing extending downwardly from the trailer. The skirt panel includes a monolithic, generally-rectangular composite reinforced thermoplastic structure, having vertical lateral side edges configured and arranged for connection to associated vertical lateral side edges of abutting similar skirt panels. This provides a longitudinally-extending fairing for extending contiguously on each side of the trailer, a front face of the thermoplastic structure being provided with a plurality of longitudinally-extending, vertically-spaced-apart arcuate protrusions. The outer face of the thermoplastic panel preferably also is provided with dimples. The reinforcing comprising a panel secured to an inner face of the skirt panel and is provided with laterally-extending means whereby abutting skirt panels are secured to one another; whereby, when said fairing is secured to a lower portion of said trailer, the fairing extends downwardly from the trailer to from 60% to 80% of the distance to the road, so that a portion of any impinging air is directed laterally around the wheels of the rear wheel bogeys to reduce the aerodynamic drag of the trailer and of the wheel assembly.

An LED lighting device comprises: a thermally conducting body having an at least one opening that connects with a cavity within the body and a plurality of LEDs mounted in thermal communication with a face of the body and positioned around the opening. One or more passages pass through the body from the cavity to an outer surface of the body and are configured such that in operation air moves through the cavity by thermal convection thereby to provide cooling of the body. Each passage is configured in a direction that extends in a direction at an angle of about 45° to a line that is parallel with the axis of the body toward the outer surface of the body away from the face. The body can be configured such that its outer surface has a form factor resembling an incandescent light bulb or halogen reflector lamp.

Aerodynamically efficient air flow management in axial flow-turbines is provided by utilizing a variable stagger and camber airfoil. In an exemplary embodiment of the invention, this is accomplished by providing a two-piece airfoil including a strut and a flap, each of which is mounted to articulate about a common, radially oriented axis. The strut and flap are respectively positioned by a strut gear and a flap gear, located at the radial end of the airfoil and, in an exemplary embodiment, are driven by a stepped synchronizing ring.

A more efficient cooling system for densely packed electronic components for use in an out-of-doors equipment enclosure. An array of cooling assemblies are placed on heat generating components mounted to printed circuit boards mounted in enclosure racks. Each board has a manifold for intake and exhaust of refrigerant, and larger rack manifolds are substituted for rails and are attached to a backplane. A hybrid package including a ceramic hybrid power module and an attached array of cooling assemblies provide even more density of components and improved cooling.

A laptop elevation device (1) that attaches to a bottom surface (13) of a laptop (12). Each laptop elevation device has a fold-up leg (2) pivotally or hingedly attached to a base (3). An arm (5) is pivotally attached to the base. When the laptop elevation device is in an open position, the arm may be folded downward to engage one of a plurality of holes (9) located on the leg, thereby locking the laptop elevation device at a desired height. The base may be built into a laptop or attached to the underside of an existing laptop using an attachment means (14). The leg may also have a layer of rubber (11) to prevent the leg from slipping while in use. A clip (11) located on the base locks the leg and arm in place while the laptop elevation device is in folded position. An additional feature of the laptop elevation device is one or more non-slip strips (20) that attach to the underside of a laptop to allow the front portion of the laptop to hang over the edge of a flat surface (22) while the laptop is in an elevated position. An alternative embodiment of the laptop elevation device provides a handle (17) for carrying the laptop computer.

A cooling door assembly includes a frame and a cooling door coupled to the frame. The cooling door includes one or more heat exchangers. The frame is configured to mount to the back of a server rack or other electronics enclosure in such a manner that the cooling door opens to allow access to the electronics servers within the server rack while maintaining a fluidic connection to an external cooling system. The frame is coupled to the external cooling system and the cooling door includes swivel joints configured to provide a fluid path between the cooling door and the frame. In this manner, the frame remains in a fixed position, while the cooling door is configured to rotate relative to the frame so as to open and close, while maintaining the fluid path through the swivel joint.

An outdoor equipment cabinet includes a housing with an equipment compartment therein. An intake air vent and an exit air vent are formed in the housing. A fan is mounted within the housing for pulling air into the intake air vent, moving an air stream through the equipment compartment, and pushing air out of the exit air vent. A membrane is disposed adjacent the intake air vent. The membrane allows air to pass therethrough, but resists the passage of water and contaminants therethrough. In some embodiments, a baffling plate is disposed to direct the air stream within the equipment compartment, and / or the fan speed is controlled by a temperature sensor, and / or a clogging of the membrane is monitored and reported, and / or the intake air vent is located in a first door and the exit air vent is located in a second door of the cabinet.
