Abstract: A gas turbine engine includes a rotor that that has a seal surface, a shaft that has an annular seal channel that opens to the seal surface, and a seal disposed in the annular seal channel for sealing against the seal surface. The seal is made of a composite having carbon fibers disposed in a carbon matrix.

Abstract: A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

Abstract: The technology employs a holistic approach to passenger pickups and other wayfinding situations. This includes identifying where passengers are relative to the vehicle and/or the pickup location. Information synthesis from different sensors, agent behavior prediction models, and real-time situational awareness are employed to identify the likelihood that the passenger to be picked up is at a given location at a particular point in time, with sufficient confidence. The system can provide adaptive navigation by helping passengers understand their distance and direction to the vehicle, for instance using various cues via an app on the person's device. Rider support tools may be provided, which enable a remote agent to interact with a customer via that person's device, such as using the camera on the device to provide wayfinding support to enable the person to find their vehicle. Ride support may also use sensor information from the vehicle when providing wayfinding support.

Abstract: A process of 3D scanning lactating women's breasts to generate an AutoCAD model of the maternal nipple is disclosed. The 3D scanning and generation of a plurality of maternal nipple shapes for creation of breastfeeding accessories and molds is intended to closely mimic a specific mother's unique nipple shape, which can vary widely from one woman to another. The embodiments eliminate nipple confusion in infants being introduced to a bottle nipple and pacifier, in order to promote prolonged breastfeeding. Mimicking a mother's unique nipple shape helps create accessories that better fit a mother's unique nipple size and shape and decrease pain (i.e. pump flange and nipple shield).
