Abstract: An electric motor has a stator defining multiple stator poles with associated electrical windings, and a rotor having multiple rotor poles. The rotor has flux barriers between adjacent rotor poles, the flux barriers each having a material with an electrical conductivity higher than the rotor pole material. The flux barriers are electrically isolated from one another external to the ferromagnetic material. Eddy currents are induced in the flux barrier to cause destructive interference of an impending magnetic field, such that the flux barrier effectively acts to inhibit magnetic flux during motor operation, which in some cases will result in a repulsive force that will act to increase an induced motive force on the rotor poles.

Abstract: A device configured to guide creation of an incision in a sclera of an eye including an elongate handle and a footplate having a plurality of struts defining a central opening extending between an upper surface and a lower surface of the footplate. A first strut of the plurality of struts has a proximal-facing blade guide surface that is straight and extends between two lateral struts of the plurality of struts. A second strut of the plurality of struts has a proximal-facing limbal guide surface that is curved. The blade guide surface is separated a distance from the limbal guide surface to identify a target location for creating an incision relative to a limbus of the eye. The blade guide surface has a length between the two lateral struts that limits a length of the incision that can be created using a cutting blade inserted through the central opening.

Abstract: UPS systems, methods, and computer-readable mediums utilizing electromechanical bypass relays to switch from an on-line mode of operation to a green/bypass mode of operation include control logic to adaptively adjust the timing of when an inverter of a UPS turns off to prevent backfeeding a utility. After the UPS is instructed to transition from the on-line mode to the green mode, a monitoring period begins. During the monitoring period, a parameter related to the output current of the inverter is monitored and compared to a predetermined threshold. If the parameter exceeds the predetermined threshold before a fixed period time has elapsed, the inverter is turned off early. If the inverter current does not exceed the predetermined value within the fixed period of time, the inverter is turned off.

Abstract: Systems and methods are described herein for more efficiently updating a data directory, which maps data objects stored by a data storage service, such as maintained by on premise computing resources of a client of the data storage service. In one example, event data corresponding to operations performed on a plurality of data objects stored in a data storage partition of a data storage service may be obtained. A set of data objects relevant to a directory maintained locally by a client device may be determined. The event data may be filtered, such as by removing entries of the plurality of entries not corresponding to the set of data objects. The filtered event data may then be stored or pushed to a client device, to cause the directory to be updated, without requiring a full examination of the data storage partition.

Abstract: An electric motor has a stator mechanically coupled to the rotor by a nutating traction interface, such that during nutation of the rotor with respect to the stator a tilt axis of the rotor progresses about the axis of rotation of the output shaft. The rotor and a surface of the stator bound a dynamic gap across which a magnetic field is produced by electrical activation of the motor to generate a force between the rotor and the stator. The traction interface and the gap are arranged such that, in a plane containing the axis of rotation of the output shaft, the traction interface is angled with respect to the stator surface bounding the gap. The rotor is connected to the output shaft by a tiltable connection such as a gimbal.
