Abstract: A vehicle includes an instrument panel, a support structure coupled to the instrument panel, and a retainer. The support structure defines a receiver that extends from a lower end to an upper end that is vehicle-upward of the lower end. The portion of the support structure that defines the receiver includes at least one rib that protrudes into the receiver. The retainer includes a barrel portion having a threaded interior surface that defines a hollow and an exterior surface opposite the interior surface and having at least one wing. The retainer also includes a head portion coupled to the barrel portion. The retainer is operably coupled to the support structure, such that the barrel portion is received within the receiver and the at least one wing of the exterior surface is engaged with the at least one rib to maintain the retainer within the receiver.

Abstract: Systems and methods are provided for enhanced vacuum bags. One embodiment is a method that includes placing a laminate comprising uncured fiber reinforced polymer onto a mandrel, laying up a vacuum bag, which includes integral ultrasonic transducers within a gas-impermeable layer, atop the laminate, and sealing the vacuum bag to the mandrel. The method also includes drawing a vacuum on the laminate via the vacuum bag, removing gas between the integral ultrasonic transducers and the laminate, and interrogating the laminate with the integral ultrasonic transducers.

Abstract: Methods for machining a composite material substrate are discloses comprising integrating a predetermined pattern area having a disbond material for the purpose of creating a disbond region into the composite material substrate at a predetermined thickness, detecting the disbond region and forming a plurality of recesses in the composite material substrate by removing a machined plug from the composite material substrate to form recesses positioned at locations corresponding to the predetermined pattern area, and composite components comprising the recesses machined according to such methods.

Abstract: Disclosed is a configuration for determining a genotyping label composition of a target individual using direct acyclic paths. The configuration includes receiving a phased genotype of the target individual, including a first haplotype and a second haplotype. The configuration initiates a full-ethnicity hidden Markov model (HMM) including nodes with a set of ethnicity labels. The first haplotype is input to determine a first subset of ethnicity labels that match the first haplotype. The second haplotype is input to determine a second subset of ethnicity labels that match the second haplotype. The first and second subsets of ethnicity labels are combined to create a candidate subset of ethnicity labels for the target individual. The configuration initiates a simplified HMM with nodes from the candidate subset of ethnicity labels. The phased genotype of the target individual is input to the simplified HMM to determine genotyping label composition of the target individual.
