Abstract: The present disclosure relates to aerosol delivery devices, methods of producing such devices, and elements of such devices. In some embodiments, the present disclosure provides devices configured for vaporization of an aerosol precursor composition that is contained in a reservoir and transported to a heating element by a liquid transport element. The liquid transport element may include a porous monolith.

Abstract: A light emitting diode (LED) assembly is provided for use as an airplane position light which meets Federal Aviation Regulation lighting requirements and lasts longer than conventional incandescent and halogen position lights, while being relatively lightweight, cheap, and requiring relatively little power for operation. The LED assembly includes a first plurality of circuit boards in electrical communication with a base circuit board, wherein each circuit board of the first plurality of circuit boards is parallel to every other one of the first plurality of circuit boards, but is disposed at an acute angle to the base circuit board. The LED assembly also includes a second plurality of circuit boards in electrical communication with the base circuit board, wherein each circuit board of the second plurality of circuit boards is disposed at a different angle to the base circuit board such that the second plurality of circuit boards form a fan-shaped structure.

Abstract: Method and apparatus for measuring thermal radiation emitted by a sample, and for determining emissivity. The apparatus comprises a chamber in which the sample may be positioned, the chamber comprising a plurality of walls including a first wall containing an observation port. The chamber is located in a cold environment, and the walls of the chamber are brought to a selected temperature by circulating a temperature conditioned fluid through the walls. The sample is moved along a movement axis within the chamber past the observation port. As the sample is so moved, radiation emitted outwards through the observation port by the sample is measured.
