Abstract: A system includes a computing platform having a hardware processor and a memory storing software code, a memory data structure storing memory features for an artificial intelligence interactive character (AIIC), and a trained machine learning (ML) model. The hardware processor executes the software code to receive interaction data describing a communication by a user with the AIIC, predict, using the trained ML model and the interaction data, at least one user memory feature(s) of the communication, and identify, using the memory data structure, one or more of the memory features for the AIIC as corresponding to the user memory feature(s). The software code also determines, using the user memory feature(s) and the corresponding one or more of the memory features for the AIIC, an interactive communication for execution by the AIIC in response to the communication by the user; and outputs the interactive communication to the AIIC.

Abstract: A system includes a computing platform having a hardware processor and a memory storing software code, a memory data structure storing memory features for an artificial intelligence interactive character (AIIC), and a trained machine learning (ML) model. The software code is executed to elicit, using the AIIC, a reminiscence from a user, predict, using the trained ML model and the reminiscence, one or more user memory feature(s) of the reminiscence, identify, using the memory data structure, one or more of the memory features for the AIIC as corresponding to the user memory feature(s), and determine, using the user memory feature(s), a mood modifier for a creative composition. The software code is further executed to produce, based on the mood modifier and the corresponding one or more of the plurality of memory features for the AIIC, the creative composition, and provide the creative composition to the AIIC.

Abstract: A cooling jacket for an electric motor comprises a fluid passage disposed adjacent to a stator and configured to convey a cooling fluid. The cooling jacket includes a flow mixing enhancer within the fluid passage adjacent an axial end of the stator. The flow mixing enhancer includes baffles, a porous fibrous structure, and/or an open-cell foam to provide greater thermal conductance at a region adjacent to the axial ends than it provides to a central region therebetween. A flow bridge directs the cooling fluid through circumferential flow paths adjacent to both of the axial ends before the cooling fluid is circulated in a central flow path around the central region of the stator. One or more nozzles direct a jet of cooling fluid upon the stator end winding, a rotor end winding, and/or printed circuit board. A ring-shaped coolant header may supply the cooling fluid to the nozzles.

Abstract: In distributed green-energy architectures, where a customer location has energy storage as well as local generation, the present application provides techniques which advantageously prevent the battery from being charged from the grid. This is preferably implemented by using voltage-level signaling to limit power transfer from grid to battery, thereby 1) allowing transfer from PV to battery, and 2) preventing “round-trip” transfer of net energy from grid to battery to grid. This is particularly advantageous where net energy metering is allowed, or where any analogous form of preferential pricing is given to green energy (or to solar energy specifically).

Abstract: A storage container includes a body, a lid, and two handles. The body defines a compartment between first and second side walls of the body. The compartment is accessible along a top end of the body. The first and second side walls include respective cavities that are recessed from exterior surfaces of the side walls via rims that define perimeters of the cavities. The lid is connected to the top end of the body and encloses the compartment when in a closed position. The two handles are tethered to the body via cords, and are configured to nest within the cavities of the corresponding side walls when not grasped by a person. First and second ends of the handles are configured to engage opposing portions of the corresponding rim to retain the handle nested in the cavity via an interference fit.

Abstract: An active anti-islanding architecture where a power converter injects a current component at a harmonic of the fundamental power frequency is injected with a phase sequence opposite to that which normally be present with that harmonic. (For example, a 5th harmonic frequency can be used with a positive phase sequence, or a 7th harmonic frequency with a negative phase sequence.) The injected current component can have a thousandth or less of the power transferred by the converter, since the distinctive phase sequence of the injected signal facilitates recognition of a corresponding term in the observed voltage.

Abstract: Power converters, and microgrids driven by such a power converter, in which the converter is controlled by a proportional controller which operates directly on AC waveforms, preferably without conversion to a DC type signal; preferably with use of voltage compensation to remove inherent error of proportional controller; and preferably with use of individual phase RMS voltages in the voltage compensation, to allow for normal operation under any load condition. Undervoltage of one or two phases is automatically compensated by adjusting the voltage of all phases, to retain balance. Line-starting of a motor load is automatically detected, and frequency droop is driven, apart from the other control relations in the system, to complete the line-starting operation as quickly as possible.

Abstract: Methods and systems for managing link voltages in a power converter, where single phase, three phase or universal systems can be used. Common mode management refers to shifting of voltages in a particular direction to perform transition between input and output ports, in addition to maintaining soft switching property. Voltages in power converters can be freely increasing and decreasing, and thus damage to the circuit can be caused if these voltages change are not controlled.

Abstract: Methods and systems for islanding detection in power generators, particularly power converters. The present innovative methods can disconnect the power converter from the power distribution grid. Islanding detection can be performed by detecting the difference in resistive impedance between the islanded and un-islanded conditions, using an input-output power and input-output voltage correlation technique. The present methods can shut down the power converter instead of allowing it to continue running without connection to the grid, which will protect line-worker safety.

Abstract: A car charging station in which battery buffering includes at least approximately as much energy as is required to charge one car rapidly. This is particularly advantageous when a photovoltaic array is connected through a power converter to charge the battery, and also to provide a lower rate of charge directly to the vehicle charge connections. Advantageously, a mains power connection can also be made through yet another port of the same multiport power converter.
