The operations include generating a digital model from the images in the database and communicating a first portion of the digital model as an enhanced view to a user device. The first portion corresponds to a first line of sight orientation of the user device as measured by an orientation sensor. The operations include receiving a signal based on sensor data measured by the orientation sensor. The signal indicates movement of the user device from the first line of sight orientation to a second line of sight orientation. In response, the method includes communicating a second portion of the digital model to the user device that corresponds to the second line of sight orientation of the user device.

Abstract: A heat exchanger is provided having an integrally and seamlessly formed return manifold connecting multiple supply tubes and return tubes. The heat exchanger may also include a return manifold having one or more structures providing a flow restriction within or proximate the return manifold.

Abstract: Load-bearing structures constructed from polymer matrix composite (PMC) materials, and processes for their production. The structures are produced from at least one shaped panel formed of a continuous fiber reinforcement in a thermoplastic resin matrix. The shaped panel has been thermoformed to have a substantially constant cross-sectional thickness and portions that lie in different planes and are interconnected by one or more bends. The shaped panel is machined to alter its shape, and optionally to produce multiple separate subcomponents therefrom. The machined shaped panel can constitute the entire structure, or the structure can be formed by joining the machined shaped panel with other shaped panels or by joining two or more of the subcomponents. The structure can be installed on an aircraft engine to secure components to the engine.
