Abstract: Continuous skin leading edge slats are disclosed. A disclosed example leading edge slat for use with an aircraft includes a single-piece nose skin defining upper and lower external surfaces of the leading edge slat, where the single-piece nose skin is to extend between a fore end and an aft end of the leading edge slat, and a box spar coupled to an inner surface of the single-piece nose skin. The box spar includes lateral walls extending away from the inner surface of the single-piece nose skin. The lateral walls define at least one compartment of the box spar.

Abstract: Systems, methods, and software are provided for assessing manufacturing errors of a prosthetic socket to facilitate a clinical assessment of the socket. The embodiments disclosed herein may align and compare a manufactured socket shape to a desired socket shape to determine whether clinically significant errors are present in the manufactured socket. A mean radial error (MRE) may be calculated and compared to a set threshold. If the MRE falls below the threshold an interquartile range (IQR) may be calculated and compared to an IQR threshold. If the IQR falls below the IQR threshold, surface normal angle errors (SNAE) may be calculated and plotted to the surface model. If the SNAE plot does not include closed contour regions, the socket may proceed to patient fitting. If the MRE or IQR thresholds are exceeded, or if the SNAE plot indicates closed contour regions, the socket may be reshaped accordingly, prior to fitting.

Abstract: Systems, methods, and software are provided for modifying a prosthetic socket to better fit a residual limb of a patient. The embodiments disclosed herein may align and compare a first shape corresponding to an interior surface of the prosthetic socket or a residual limb shape to a second shape corresponding to a desired socket shape or a rectified residual limb shape. A socket insert or pad may be manufactured per the comparison. The socket insert or pad may be configured to be affixable within the patient's prosthetic socket to modify the interior surface of the prosthetic socket such that the modified prosthetic socket provides a better fit to the residual limb of the patient.

Abstract: For use in connection with evaluating prosthetic sockets (and other objects) designed and fabricated with computer aided design and manufacturing software, the shape of a socket is accurately scanned and digitized. The scanned data are then compared to either an electronic shape data file, or to the shape of another socket, a positive model of a residual limb (or socket), or a residual limb. Differences detected during the comparison can then be applied to revise the design or fabrication of the socket, to more accurately achieve a desired shape that properly fits the residual limb of a patient and can be used to solve the inverse problem by correcting for observed errors of a specific fabricator before a socket is produced. The digitizing process is implemented using a stylus ball that contacts a surface of the socket to produce data indicating the three-dimensional shape of the socket.
