The present invention generally provides improved medical devices, systems, and methods. Embodiments may be particularly well suited for the treatment of dermatological and / or cosmetic defects, and alternative embodiments may be configured for treatment of a wide range of target tissues. Some embodiments of the present invention apply cooling with at least one small, tissue-penetrating probe, the probe often comprising a needle having a size suitable for inserting through an exposed surface of the skin of a patient without leaving a visible scar. The cooling may remodel one or more target tissue so as to effect a desired change in a composition of the target tissue and / or a change in its behavior. Exemplary embodiments make use of replaceable needle probes supported by a probe body handle, with small needle probes often being replaced during treatment of a single patient. Unlike the large format cryogenic cooling systems of the past, small cryogenic cooling needle probes may dull or be damaged by insertion. Careful control over the control of cryogenic cooling fluid into a needle probe can allow the length of the active cooling to be controlled through depletion of liquid from an evaporating cryogenic cooling flow. Hence, even needles having similar external structures may provide differing lengths of an iceball along the needle axis. Surprisingly, small cryogenic cooling needles and / or other cryogenic cooling probes having a lubricious coating will allow safe removal of the probe from the treatment region while at a least a portion of the tissue remains frozen, significantly decreasing the overall time for a procedure involving many insertion / freeze / removal cycles.

Described herein is a fuel processor that produces hydrogen from a fuel source. The fuel processor comprises a reformer and burner. The reformer includes a catalyst that facilitates the production of hydrogen from the fuel source. Voluminous reformer chamber designs are provided that increase the amount of catalyst that can be used in a reformer and increase hydrogen output for a given fuel processor size. The burner provides heat to the reformer. One or more burners may be configured to surround a reformer on multiple sides to increase thermal transfer to the reformer. Dewars are also described that increase thermal management of a fuel processor and increase burner efficiency. A dewar includes one or more dewar chambers that receive inlet air before a burner receives the air. The dewar is arranged such that air passing through the dewar chamber intercepts heat generated in the burner before the heat escapes the fuel processor.

A heat dissipation system includes a heat sink, a heat pipe, and a cooling assembly. The heat sink includes a substrate and a number of fins extending therefrom. The heat sink has a receiving portion. The heat pipe includes a shell, a wick, and a working fluid contained in the shell. The heat pipe has an evaporation section and a condensation section. The evaporation section is inserted into the receiving portion of the substrate while the condensation section is equipped with the cooling assembly. A hydrophilic layer is formed on the wick so that the capillarity of the wick is enhanced. The heat dissipation system has two mechanisms by which to dissipate heat from a heat-generating component, i.e., via the heat sink and the heat pipe. Therefore, an efficiency of heat dissipation of the heat dissipation system is improved.

A lighting fixture utilizing LED light sources for illumination of commercial, outdoor and other large area applications incorporates efficient heat dissipation and improved convective air flow. An integrated heat transfer assembly is disclosed that is configured to enhance heat dissipation by providing an efficient thermal conductive pathway for radiation of heat to an external environment. The lighting fixture body is configured with a lens body and heat sink having a chimney tube with internally facing finned heat sink arrangement for providing enhanced convective air flow through the light fixture body. When the heat sink transfers heat from the LED light sources during operation so as to create heated air surrounding the heat sink, ambient air is drawn through the chimney and the heated air is exhausted through air gaps so as to create a conductive air current with the environment. The heat sink fins are configured to enhance the natural air draw through the chimney by tapering the surface areas of the fins.

A cooled airfoil includes an impingement rib having a multiple of openings which supply a cooling airflow from a cooling circuit flow path toward an airfoil leading edge. The multiple of openings are offset in the impingement rib opposite an outer airfoil wall which includes gill holes. Offsetting the multiple of openings opposite an outer airfoil wall which includes the gill holes focuses the cooling airflow across turbulators to increase the cooling airflow dwell time to increase the thermal transfer therefrom in higher temperature airfoil areas.

The floating brake rotor assembly with non-load bearing pins includes a brake rotor and hub that are coplanar and are interconnected by pin and spring assemblies such that the pins do not bear rotational torque being transferred between the brake rotor and hub. The rotor has tooth-like protruding members along its inner edge that mate with recesses along the outer edge of the hub. When aligned, each protruding member and corresponding recess forms an aperture through which a pin is positioned, and allows for transfer of rotational torque without applying load force to the pin.
