Abstract: Compressor rotor structure and methodology for harmonizing compressor aerodynamics and rotordynamics are provided. Disclosed embodiments benefit from a compressor design effective for improving rotordynamics (e.g., stiffer rotor structure) without reducing a usable aerodynamics range of the compressor. This design may involve variation of the rotor structure along the rotor axis to locate respective surfaces defined by respective inlets of the one or more impellers at a varying distance relative to the rotor axis based on respective ratios selected for the configuration of the impeller bodies. This arrangement may be effective for improving rotordynamics while satisfactorily meeting the respective varying aerodynamics requirements at the various compression stages by the impeller bodies.

Abstract: Compressor rotor structure for turbomachinery, such as a compressor, is provided. Disclosed embodiments can benefit from sealing sleeves that may be arranged to inhibit passage onto respective hirth couplings of process fluid being processed by the compressor. The sealing sleeves may be affixed to adjoining structures (e.g., adjoining impeller bodies) by way of a slip fit connection to one of the adjoining structures and an interference fit connection with respect to the other adjoining structure, which is conducive to a user-friendly assembly of the sealing sleeves with the adjoining structures.

Abstract: A compressor rotor for turbomachinery, such as a centrifugal compressor, is provided. Disclosed embodiments benefit from a seal assembly including one or more seal members positioned within a Hirth coupling to inhibit passage of process fluid being processed by the compressor. A circumferentially extending groove is arranged in a toothed meshing interface of the Hirth coupling to receive and securely hold the one or more seal members within the Hirth coupling. The groove may be configured with features, such as may define a dovetail groove, to facilitate assembly of certain seal members into the groove. Disclosed embodiments can make use of any of various sealing modalities for the seal member within the Hirth coupling based on the needs of a given application.

Abstract: Systems and methods for determining a predicted brain health of a first user and providing individualized health recommendations to the first user based at least in part on an artificial neural network trained on previously existing anatomical and functional neuroimaging information, behavioral information, self-reported information, and other types of information of a plurality of users. The artificial neural network may be capable of determining a predicted benchmark of brain health of the first user's information when compared with the previously existing users' information and storing the first user's anatomical and/or functional neuroimaging information, behavioral information, self-reported information, and other types of information in a database such that the artificial neural network can be re-trained based on the new information of the first user. The first user can be notified of his or her brain health and receive individualized health recommendations.

Abstract: A portable data exchange device including a data input, a data output, and a memory is incorporated into a mechanical or electronic key that is required for operating a motor vehicle. The data exchange device can exchange data bi-directionally or uni-directionally with a data processing device in the vehicle and with an external input/output terminal. The data may include vehicle-specific and/or driver-specific data relating to various systems of the vehicle. The data are transmitted to and from the device in the key in a wireless or direct-contacting manner. This device incorporated in the key avoids the need for carrying a separate data unit for exchanging data between the on-board data processing device of the vehicle and the external input/output terminal.

Abstract: A control unit for user-specific adjustment of device settings in a motor vehicle on the basis of user data according to a specific key, where the control unit recognizes the users in the seat positions in a motor vehicle on the basis of identification means assigned to each user. The control system is characterized by a great variability and convenience. Instead of allowing only driver-specific settings, the control system according to the present invention allows a person-specific selection of seat positions, climate control or multimedia entertainment. This is made possible by means of a seat-specific identification.
