摘要： An aircraft has a first antenna arrangement, a payload and a processing unit. The first antenna arrangement is designed to wirelessly receive electromagnetic signals. The processing unit is coupled to the first antenna arrangement, on the one hand, and to the payload, on the other hand. The processing unit is designed to modulate an electromagnetic signal received by the first antenna arrangement and thereby to generate a first modulated signal and to forward it to the payload. The payload is designed to use the first modulated signal as working signal. A radiofrequency power signal on an uplink is thus remodulated into a payload working signal, such that the payload working signal is able to be used directly by the payload without rectification into a DC voltage.

摘要： A magnetic alignment system can include a primary annular magnetic alignment component and a secondary annular magnetic alignment component. The primary alignment component can include an inner annular region having a first magnetic orientation, an outer annular region having a second magnetic orientation opposite to the first magnetic orientation, and a non-magnetized central annular region disposed between the primary inner annular region and the primary outer annular region. The secondary alignment component can have a magnetic orientation with a radial component.

摘要： A contactless device includes an impedance matching and filter circuit connected to an antenna and being on the one hand operable for contactlessly communicating with a second device via the antenna, and on the other hand operable for contactlessly charging a rechargeable power supply of a third device via the antenna. A method of control includes modifying the impedance matching and filter circuit of the contactless device depending on whether the contactless device carries out the contactless communication or carries out the contactless charging.

摘要： Eyewear and receptacles for housing such eyewear include components of a wireless power transfer system. The eyewear includes a receiver system for receiving power from a transmission system associated with the receptacle(s). The receiver system includes at least one receiver antenna, for receiving wireless power from the transmission system, and a repeater antenna for repeating the wireless power signal to the receiver antenna. The receiver antenna is positioned proximate to a first arm of the eyewear and the repeater is positioned proximate to a second arm of the eyewear. Positioning of the receiver and repeater antennas allows for positional freedom of the eyewear and/or the arms of the eyewear, when mechanically received by the receptacle.

摘要： Disclosed herein is an antenna device that includes a first coil wound in a plurality of turns, and a second coil disposed outside the first coil as viewed in a coil axis direction of the first coil. The first coil is configured such that a first interval between turns in a first direction is larger than a second interval between turns in a second direction perpendicular to the first direction. An inter-coil distance between an outer edge of the first coil and an inner edge of the second coil is larger than the second interval as viewed in the coil axis direction.

摘要： Systems, apparatuses, and methods provide for technology that locates one or more masses of an ocean-based weather system, as the ocean-based weather system starts to organize and before the ocean-based weather system spawns a land-based storm, and controls a transmission of electromagnetic radiation from the space platform to the one or more masses, wherein the transmitted electromagnetic radiation tracks the one or more masses as the ocean-based weather system is starting to organize and rotate, and wherein the transmitted electromagnetic radiation prevents the ocean-based weather system from rotating and spawning the land-based storm.

摘要： A system for wireless power networking, preferably including one or more nodes, such as transmit nodes, receive nodes, relay nodes, and/or hybrid nodes. The system may function to form a power network (e.g., mesh network) configured to transfer power wirelessly between nodes of the system. A method for wireless power networking, preferably including transmitting power, controlling relay nodes, and/or receiving power, and optionally including optimizing power network operation. The method is preferably performed at (e.g., by one or more nodes of) the system, but can additionally or alternatively be performed by any other suitable system(s).
