Abstract: An electric machine includes a stator defining multiple stator poles with associated stator windings configured to receive a stator current. The electric machine also includes a rotor defining multiple fixed rotor poles with associated rotor windings, wherein the rotor defines a field energizable by magnetic fields produced by the stator windings when receiving the stator current to produce relative motion between the rotor and the stator and wherein the rotor is maintained in synchronicity with the magnetic fields produced by the stator during operation of the electric machine. The electric machine also includes a rectification system configured control against an alternating current being induced in the rotor poles as the field is energized by magnetic fields produced by the stator windings when receiving the stator current.

Abstract: Techniques for improving a graphical user interface are described. In an example, a computer system receives an activity identifier of an activity in a video game and correlated locations. It builds a map of the locations from completion data indicating completion of the activity, and location data indicating where the activity was completed in the video game by other players. The identifier can be predefined in program code of the video game. Data is processed to determine where the likely location is for completing the activity in the video game. This likely location is shown as a graphical user interface element in a map.

Abstract: An electrical termination unit or feedthrough which may be used for routing electrical conductors through a chamber wall, or otherwise across a barrier between isolated atmospheric conditions. The electrical termination unit may have aluminum as the interface material to the chamber interface and may utilize a ceramic insulator. The electrical termination unit may have the aluminum used as the interface brazed directly to a ceramic surface of the insulator. The aluminum that forms the chamber interface may be formed within a hollow ceramic tube in the same process step that brazes the aluminum to the ceramic tube with a hermetic joint. Machining subsequent to the brazing of the aluminum to the ceramic insulator may allow for achievement of the final form desired. A method for manufacturing such an electrical termination unit.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for multi-jurisdictional endpoint allocation compliance. A multi-jurisdictional endpoint allocation system receives a request to allocate an endpoint in a jurisdiction to an account and accesses a regulation data object for the jurisdiction. The regulation data object identifies a set of jurisdictional requirements for the jurisdiction and a set of actions to be performed to satisfy the set of jurisdictional requirements for the jurisdiction. The multi-jurisdictional endpoint allocation system allocates an endpoint in the jurisdiction to the account and executes the set of actions associated with the regulation data object to satisfy the set of jurisdictional requirements for the jurisdiction.

Abstract: Systems and methods for sender profile and/or recipient profile disambiguation and/or confirmation are disclosed. In instances where a sender profile is not indicated by a user sending a communication from a communal device, heuristic data may be utilized to infer the sender profile. Similar heuristic data may also be used when selection of the sender profile is associated with a low confidence level. Heuristic data may also be used to infer the recipient profile when the user does not indicate the recipient profile or when selection of the recipient profile is associated with a low confidence. Various confirmations may result from the sender and recipient profile disambiguation.

Abstract: The present disclosure generally relates to writing data to streams. A host device can instruct a data storage device to operate in implied streams mode such that the host device does not need to tell the data storage device the specific stream in which to write data. The data storage device would maintain a list of open append points of specific streams. Upon receiving a write command, the data storage device determines whether the write command is for an already open stream, and if so, write to the specific stream. If not, then the data storage device opens a new stream or write the data to an overflow stream.
