Abstract: An example system for inspecting a surface includes a laser, an optical system, a gated camera, and a control system. The laser is configured to emit pulses of light, with respective wavelengths of the pulses of light varying over time. The optical system includes at least one optical element, and is configured to direct light emitted by the laser to points along a scan line one point at a time. The gated camera is configured to record a fluorescent response of the surface from light having each wavelength of a plurality of wavelengths at each point along the scan line. The control system is configured to control the gated camera such that an aperture of the gated camera is open during fluorescence of the surface but closed during exposure of the surface to light emitted by the laser.

Abstract: An electrically conductive patch for a sheet that is part of a skin of an aircraft is disclosed. The sheet includes an outermost surface constructed of an electrically conductive material and one or more electrical discharge points that are conductively coupled to the outermost surface of the sheet. The electrically conductive patch is disposed along the outermost surface of the sheet and is conductively coupled to the outermost surface of the sheet. The electrically conductive patch is constructed of a voltage responsive film configured to change from a first coloration and into a second coloration in response to experiencing a threshold voltage difference, where the first coloration substantially matches a coloration of the skin of the aircraft.

Abstract: In an example, a method for accelerated conditioning of a composite core sandwich coupon is described. The method includes setting a first temperature and a first relative humidity level of the conditioning apparatus, wherein a combination of the first temperature and the first relative humidity level correspond to a desired relative humidity level of the plurality of cells of the core layer at room temperature. The method includes maintaining the first temperature and the first relative humidity for a first period, wherein during the first period a core humidity of the plurality of cells in the core layer approaches the first relative humidity level. The method includes determining that the core humidity has reached the first relative humidity level. The method includes, based on determining that the core humidity has reached the first relative humidity level, adjusting the first temperature to a second temperature.

Abstract: Described herein is a method of inspecting a part for defects. The method includes applying an electromagnetic field to the part using a defect detection coil and one or more noise cancelation coils. The method also includes detecting feedback received in response to applying the electromagnetic field. The method includes adjusting settings corresponding to the one or more noise cancelation coils, in response to the feedback, to reduce electromagnetic noise.

Abstract: A self-forming sealant system forms a seal between two parts or between a fastener and a part of a structure. In forming the seal, a first finish having a high surface energy is applied to the joint between the two parts or is applied to the fastener and the part. A second finish having a low surface energy is then applied adjacent to the area where the first finish was applied. A sealant is then applied to the joint between the two parts or the fastener and the part, where the sealant migrates to the joint or fastener coated with the first finish having the high surface energy and away from the areas adjacent the joint or the fastener coated by the second finish having the low surface energy.

Abstract: A method of producing super resolution images includes a detector array capturing images of a scene in which detector array provides pixels for respective portions of the scene, and the detector array captures the images in increments in each of which a lens or the detector array is moved a length of an individual detector. The method also includes a processing unit determining light intensities of the pixels, and calibrating the pixels to a reference pixel based on the light intensities and thereby compensate for any differences in sensitivity of the individual detectors. This calibration is based on a comparison of light intensities of the reference pixel and an other pixel in respectively one and an other of the images in which the portion of the scene is the same for the reference pixel in the one of the images and the other pixel in the other of the images.

Abstract: A plurality of micro-electro-mechanical system (MEMS) transducers in a phased array are coupled to a flexible substrate using carbon nanotubes (CNTs) for conformal ultrasound scanning. Each transducer comprises a cantilever, magnetic material deposited on the cantilever, and a solenoid positioned relative to the magnetic material. The carbon nanotubes are grown on the cantilever and mechanically couple the transducer to one side of the flexible substrate. The other side of the flexible substrate is applied to a surface of a part under inspection, and the transducers are electrically connected to a processer to cause movement of the cantilevers when the solenoids are energized by the processor. The movement of the cantilevers results in movement of the carbon nanotubes, which imparts a force to the flexible substrate that results in ultrasound waves, which permeate the part. Returns from the ultrasound waves are interpreted by the processor to generate images of the part.

Abstract: In one aspect, methods of making semiconducting single-walled carbon nanotubes are described herein. In some implementations, a method of making semiconducting single-walled carbon nanotubes comprises providing a plurality of semiconducting nanotube seeds including (n,m) nanotube seeds and non-(n,m) nanotube seeds. The method further comprises illuminating the plurality of nanotube seeds with a first laser beam having a first wavelength and a second laser beam having a second wavelength, the second wavelength differing from the first wavelength. The first wavelength corresponds to an absorption maximum for a (n,m) carbon nanotube and the second wavelength corresponds to a photoluminescence emission frequency for the (n,m) carbon nanotube.
