Abstract: Disclosed are implementations that include a power converter system and method including an N-phase power converter stage having to an alternating current (AC) side and a direct current (DC) side, with N > 1. The system and method further include an N-phase LC filter comprising one or more capacitors, wherein respective one or more neutral points of the one or more capacitors are electrically connected to a DC negative terminal of a DC source. A control system drives power switching elements of the N-phase power converter stage to convert received power and to output converted power. The control system drives the power switching elements using variable frequency soft switching at a frequency of at least 20 kHz. The power converter may have bidirectional operation to operate in a traction mode to drive a motor or a charging mode to charge a DC source.

The converter further includes a power switching element pair including a high side switch and a low side switch coupled together at a midpoint node. The converter further includes an LC filter having a switch-side inductor, a lower capacitor coupled between a second end of switch- side inductor and the negative DC terminal; and an upper capacitor coupled between the second end of the switch-side inductor and the positive DC terminal. The converter may further include drain-source capacitors coupled across the drain and source terminals of the switches.

Abstract: A stator defines multiple stator poles with associated stator windings. A rotor defines multiple rotor poles with associated rotor windings configured to be energized substantially by the stator. The rotor defines a rotor field energizable by magnetic fields produced by the stator windings to produce relative force between the rotor and the stator. An active rectifier is conductively coupled to one or more first rotor windings. The active rectifier is configured to control a direction of current flow through the one or more first rotor windings responsive to a signal received wirelessly from the stator by one or more second rotor windings.

Abstract: Systems and methods may involve processing of entity data by machine learning models to produce one or more entity and/ aggregate risk scores and/or aggregate anticipated risk scores, which may be compared to one or more thresholds to determine when one or more predefined actions should be taken. The entity data may be collected for various entities related to an exam registration and delivery process, which may include a candidate, an exam, a test center, an exam registration event, a proctor, and an exam delivery event. The exam registration and delivery process may include multiple states - each being associated with a different set of entities. Aggregate risk scores for a given state may be calculated using only entity data for the set of entities associated with that state. The predetermined actions taken may also be dependent on the current state.

Abstract: An in-game video game editing system and method is provided. An electronic processor executes a game software application to generate, on a display, a graphical gameplay interface including a plurality of sprites and a graphical editing panel listing predetermined modifications. The electronic processor receives a selection of one of the predetermined modifications ad determines a type of the predetermined modification. The type indicates whether the predetermined modification includes adding a new sprite or selecting an existing sprite. Based on the type, an existing sprite is selected from the graphical gameplay interface. The electronic processor then adds a block of code to the selected sprite based on the predetermined modification to generate a modified sprite, and executes the block of code to provide the modified sprite on the graphical gameplay interface.

Abstract: An intraoral x-ray sensor with embedded standard computer interface. The sensor includes a data transfer cable with improved mechanical strength and heat transferring properties. The cable is quad-twisted USB cable and includes two data lines, a ground line, and fillers twisted within a metallic sheath, e.g., a metal braided shield. The cable is symmetrically organized about a centerline. The symmetric cable has an improved life due to the ability to withstand mechanical stress (e.g., rotational stress). The sensor includes a processor and a housing with an inner metallization layer. The sheath is coupled to the inner metallization layer to transfer heat generated by the processor from the inner metallization layer to the sheath.

Abstract: A stator defines multiple stator poles with associated stator windings. A rotor defines multiple fixed rotor poles with associated teeth with a ferromagnetic material. The fixed rotor poles have associated rotor windings configured to be energized substantially by the stator. Each of the rotor windings is associated with the tooth. Each of the rotor windings includes an alternating current (AC) coil (or auxiliary coil) configured to carry an AC current induced by an AC current flowing in the stator. A direct current (DC) coil (or primary coil) defines a rotor field energizable by magnetic fields produced by the stator windings to produce relative forces between the rotor and the stator. The DC coil is at least partially powered or controlled by the AC coil.
