  • Patent number: 11644146
    Abstract: A three-dimensional multi-shell insulation configured to conform to the shape of a spacecraft component to be insulated. The insulation may have a plurality of nested shell layers that are displaceable relative to each other for providing natural separation between the shell layers when the insulation is used in low-pressure and/or low-gravity space-related applications. To establish the spacing between shell layers, an edge clamp may be operatively coupled to an edge portion on at least one side of each shell layer. The shell layers may have sufficient flexibility and/or may be sufficiently displaceable relative to each other to allow the insulation to be installed or removed from the spacecraft component. One or more restraints may be provided in the space between the shell layers for restricting the relative lateral and/or transverse movement between shell layers for preventing contact. Additive manufacturing may be employed to fabricate the insulation and integrate features.

    Abstract: A light source, calibration device and method of calibrating an imaging device is disclose. The calibration device includes the light source which includes an ultraviolet light layer that, in operation, generates ultraviolet light, and a quantum dot layer that absorbs the ultraviolet light and, in response, generates radiation within the near infrared region at a selected intensity. The near infrared light is received at the selected intensity at the imaging device and a sensitivity of the imaging device is altered to detect the near infrared light at the selected intensity provided by the light source.
