Abstract: Aspects disclosed herein provide an operator training system that can train an operator about basic machine movements, operations, and applications, such as asphalt compactor rolling patterns, paving-by-numbers, milling-by-numbers, etc. with the use of a virtual reality headset at any point or time on a work site. The operator training system uses data received from the virtual reality headset and associated hand controls to guide the operator via training scenarios. The operator training system also includes providing immediate feedback on the outcome of the training scenario and may also identify one or more areas of improvement.

Abstract: Aspects disclosed herein provide a learning management system associated with a learning environment. The learning management system may be accessed via a credentialed sign-in procedure. Once the credentials are verified, a user may be provided a tailored experience based on their account. The learning management system may provide offerings of different training scenarios and also for tracking and reviewing of assessments associated with completed training scenarios.

Abstract: A gas turbine ring segment (10) for use in gas turbine engines made from a ceramic matrix composite (CMC) material is disclosed. The ring segment includes a stacked multiplicity of CMC thin-sheet lamellae (25a, 25b) each comprising a peripheral surface collectively defining a cross-section profile of the ring segment. The lamellae collectively define a channel (11) formed in the center thereof for receiving a bow-tie member (27). The bow-tie member is disposed in the channel for holding together the stacked lamellae in a through thickness direction, and the in-plane strength of the bow-tie member is perpendicular to the in-plane strength of the lamellae. A stem portion (33) of the assembly may be further secured with a wrap (38) of CMC ribbon.

Abstract: A gasket assembly is formed at least two carrier layers laminated together and formed with at least one opening through the carrier corresponding to openings across a parting plane of two members to be sealed. an elastomeric seal is molded to the carrier to define sealing beads on opposite sides of the carrier adjacent the opening with respective contact surfaces which engage the members to be scaled. The sealing contact surfaces are asymmetrically arranged contact surfaces are asymmetrically arranged relative to one another across the carrier to accommodate associated misalignment of the openings of the members to be sealed across the parting plane.
