Abstract: An inductive charging system for charging an electric vehicle, the inductive charging system comprising: an onboard vehicle assembly, which includes a receiver module comprising a receiver coil that defines a central aperture, an apertured metal shielding layer and a series of ferrite bars between the receiver coil and the apertured metal shielding layer, the series of ferrite bars radiating outward from the central aperture; and a charging station assembly, which includes a transmitter module comprising a transmitter coil that defines a central aperture, an apertured metal shielding layer and a series of ferrite bars between the transmitter coil and the apertured metal shielding layer, the series of ferrite bars radiating outward from the central aperture, wherein the receiver coil and the transmitter coil are a matching geometry of polygons having four to ten sides with central apertures that are a matching geometry to the matching geometry of polygons.

Abstract: A heat pump system is provided. The heat pump system includes a first compressor and a second compressor and a first heat exchanger, a second heat exchanger, and a third heat exchanger. The system further includes a first expansion device, a second expansion device, and a third expansion device. When the system operates in a cascade heating mode, the third heat exchanger is configured to: receive a first portion of refrigerant from the first compressor and a second portion of refrigerant from the second compressor, and provide a first consistent flow of refrigerant to the first compressor and a second consistent flow of refrigerant to the second compressor so as to improve an efficiency of the system.
