    摘要: Dual flow auxiliary power unit (APU) inlets and associated systems and methods are disclosed. An inlet in accordance with one embodiment of the invention includes an entrance aperture and a divider positioned in the inlet and located to separate a first portion of the inlet from a second portion of the inlet. The first portion can be configured to couple to an engine air intake of an APU, and the second portion can be configured to direct air away from the air intake. The divider can be positioned to direct air having a first total pressure level and a first distortion level to the first portion of the inlet, and direct air having a second total pressure level and second distortion level to the second portion of the inlet. The first total pressure level can be approximately the same as or higher than the second total pressure level, or the second distortion level can be approximately the same as or higher than the first distortion level, or both.

    摘要: A passive cooling system for aircraft auxiliary power units having an intake duct extending between an inlet opening and the compartment in which the auxiliary power unit is positioned. An inlet scoop is positioned in the intake duct for diverting a portion of the airflow in the intake duct through an outlet in a wall of the intake duct. A vacuum duct is positioned near an oil cooler for the auxiliary power unit, and an aspirator is operatively positioned between the vacuum duct and an exhaust passage of the auxiliary power unit. The aspirator creates a low-pressure region in the vacuum duct that draws the diverted air out of the outlet and through the oil cooler.

    摘要: The present invention relates to the field of optical imaging and therapeutics. More particularly, embodiments of the present invention provide minimally-invasive Fiberoptic Microneedle Devices (FMDs) for light-based therapeutics, which physically penetrate tissue and deliver light directly into the target area below the skin surface (FIG. 1). A preferred embodiment of the invention is a fiberoptic microneedle device comprising: (a) one or more silica-based needles capable of guiding light and comprising a length of about 0.5-6 mm, a base having an outer diameter in the range of about 100-150 micron, and a tip having an outer diameter in the range of about 5-20 micron; (b) a support member to which the needles are secured; (c) a ferrule comprising one or more holes for each of the needles, wherein the ferrule is operably configured to provide mechanical support to each needle at all or some portion of the length of the needle. Embodiments of the invention enable depth-selective and deep photothermal therapeutics and can be adapted for use with any laser-based treatment or diagnostic in which light is used to detect or treat targets under or on the skin surface.
