Abstract: A wall structure is provided for an aircraft. This wall structure includes a first wall section, a second wall section and a fastener system fastening the second wall section to the first wall section. The second wall section includes an aperture extending axially along an axis through the second wall section. The second wall section is axially spaced from the first wall section. The fastener system includes a mount and a retainer. The mount is connected to the first wall section. The mount includes a post that projects axially into the aperture. The retainer includes a head and a spring clip connected to the head. The head axially engages the second wall section. The spring clip is disposed in the aperture and is mated with the post.

Abstract: A latch mechanism configured to engage a mating pin is disclosed. In various embodiments, the latch mechanism includes a latch frame; a latch arm pivotally mounted to the latch frame at a pivot axis; and a bias member configured to apply a load to the latch arm in a transverse direction generally perpendicular to the pivot axis and to bias the latch arm from rotating in a first rotational direction about the pivot axis and from rotating away from the mating pin.

Abstract: The invention relates to a method for calculating the focal stack associated with an object space from the plenoptic function thereof, using a sum transform along the length of constrained planes in discrete hypercubes, which allows the computing time to be considerably reduced. The invention also relates to a method for increasing the resolution of the focal stack obtained. In addition, the invention relates to two methods for the real-time recovery of the depths and moduli and phases of the complex amplitude of the wavefront respectively in each position of the surfaces of a three-dimensional scene and to a system adapted for carrying out the aforementioned methods.

Abstract: A system consisting of a phase camera with microlenses placed in the focal point of a converging lens, wherein the camera data, processed using a combined Fourier “Slice” and fast Fourier transform edge detection technique, provide both a three-dimensional wavefront map and a real scene depth map within a broad range of volumes. The invention is suitable for use in any field where wavefronts need to be known such as earth-based astronomical observation, ophthalmology, etc., as well as in fields requiring metrology, e.g. real scenes, CCD polishing, automobile mechanics, etc. The invention is applied to the particular case of atmospheric tomography using ELTs (large-diameter telescopes: 50 or 100 meters).
