摘要： Embodiments are directed towards a multi-stage wireless power transmission system that includes a transmitting unit and a receiving unit. The transmitting unit transmits a power beam to the receiving unit, which converts the power beam into local electrical power and provides it to a personal electronic device without a corded connection between the receiving unit and a mains power supply. The transmitting unit includes a light-based transmitter to generate and transmit a power beam towards the receiving unit. The receiving unit includes a receiver to receive at least a portion of the power beam and to convert the received power beam into local electrical power. The receiving unit also includes a power output unit to provide the received local power to a personal electronic device when the personal electronic device, which is separable from the receiving unit, is electrically coupled to the power output unit.

摘要： A free-space power receiver includes layouts of photovoltaic cells selected to optimize power extraction even when a power beam moves or changes profile on the receiver. The receiver may also include a circuit board having apertures therein whereby light may reach the photovoltaic cells. The circuit board may include suitable wiring for connecting the photovoltaic cells to one another and to a load for extraction of power.

摘要： The plurality of emitters and the plurality of detectors form a light curtain that is patterned about the beam, and are positioned to surround the beam. The plurality of emitters each have a centerline and each have a divergence angle centered on the centerline. The placement and orientation of the plurality of emitters about the acceptance centerline of the beam receiver are configured to align the centerlines of the plurality of emitters substantially parallel to the incoming beam. The detection of one or more of the plurality of emitters by one or more of the plurality of detectors depends on the divergence angles of each of the plurality of emitters and the tilt of the beam receiver relative to the beam centerline.

摘要： A dual-use electromagnetic beam system may be used as a remote power delivery system when not needed as an offensive weapon. For example, a system for disabling or destroying uncooperative or enemy assets such as UAVs or ground vehicles may be used during “down time” to provide power to assets that are separated from prime power sources by distance or by logistics.

摘要： A reflector assembly at a power beam receiver includes at least two sets of reflection surfaces positioned to shift some incoming light away from the center of the beam and towards the periphery. These surfaces may be positioned obliquely to one another, for example orthogonally. By shifting a portion of the power beam away from a higher-intensity center and toward a lower-intensity periphery, the reflector assembly may improve receiver efficiency without substantial redirection of power outside of a power-collecting surface of the receiver.

摘要： A device for converting electromagnetic radiation into electricity comprises an expander that includes a conical shape having an axis and a curved surface that is configured to reflect electromagnetic radiation away from the axis to expand a beam of the electromagnetic radiation; and one or more energy conversion components configured to receive a beam of electromagnetic radiation expanded by the expander, and to generate electricity from the expanded beam of electromagnetic radiation. With the expander's curved surface, a beam of electromagnetic radiation that is highly concentrated—has a large radiation flux—may be converted into a beam that has a larger cross-sectional area. Moreover, one can configure, if desired, the curved surface to provide a substantially uniform distribution of radiation across the expanded cross-sectional area. With such an expanded beam the one or more energy conversion components can efficiently convert some of the electromagnetic radiation into electricity.

摘要： A commercially available vehicle is modified by coupling a beamed-power transmission system to the vehicle's frame. The beamed-power transmission system is arranged to deliver beamed power to a remote device such as an unmanned aerial vehicle (i.e., UAV or drone). The cooling system of the vehicle is used to cool portions of the beamed-power transmission system. An aiming system aims a power beam produced by the beamed-power transmitter toward the remote device, and a stability system coupled to both the vehicle frame and the beamed-power transmission system maintains three-dimensional constancy of the power beam even when the vehicle frame is in motion. The commercially available vehicle may be an electric vehicle, a gas-electric hybrid vehicle, or the like having a power source that includes batteries, a fuel-cells, or a generator.
