Abstract:
Wireless power transfer is received using a magneto mechanical system. A magneto mechanical system may include an array of magneto-mechanical oscillators, wherein each oscillator may comprise a magnetic symmetrical part and a suspension engaged to the magnetic part. The system may further include a coil formed around the array and electromagnetically coupled to the oscillators to produce an electric current caused by electromagnetic coupling with the oscillators.
Abstract:
Exemplary embodiments are directed to wireless power transfer. A wireless power receiver includes a receive antenna for coupling with a transmit antenna of transmitter generating a magnetic near field. The receive antenna receives wireless power from the magnetic near field and includes a resonant tank and a parasitic resonant tank wirelessly coupled to the resonant tank. A wireless power transmitter includes a transmit antenna for coupling with a receive antenna of a receiver. The transmit antenna generates a magnetic near field for transmission of wireless power and includes a resonant tank and a parasitic resonant tank coupled to the resonant tank.
Abstract:
This disclosure provides systems, methods and apparatus for wirelessly transmitting power while avoiding interference with wireless communication devices. In one aspect a wireless power transmitter apparatus is provided. The wireless power transmitter apparatus includes a transmit circuit configured to wirelessly transmit power at a transmit frequency to a first receiver device. The wireless power transmitter apparatus further includes a controller circuit configured to reduce a level of emission of the transmit circuit at a determined frequency during a period of time based on information about an information signal transmitted to a second receiver device substantially at the determined frequency to be received within the period of time.
Abstract:
Exemplary embodiments are directed to wireless power. A wireless charging device may comprise a charging region configured for placement of one or more chargeable devices. The charging device may further include at least one transmit antenna configured for transmitting wireless power within the charging region. Furthermore, the charging device is configured to exchange data between at least one chargeable device of the one or more chargeable devices.
Abstract:
A wireless power system includes a power source, power receiver, and components thereof. A current sensor senses the amount of current through the antenna. That amount of current is then used to adjust characteristics of the transmitting or receiving.
Abstract:
A wireless powering and charging system is described. The antennas can be high q loop antennas. The antennas can use coupling between a first part and a second part.
Abstract:
A power transmission system produces a magnetic field at a source that is wirelessly coupled to a receiver. Both the source and receiver are capacitively coupled LC circuits, driven at or near resonance.
