摘要： The present application relates to an apparatus which comprises a wireless power transfer (WPT) system. This system comprises features which allow it to transfer more power wirelessly at extended distances than other systems operating in the same frequency range. The system possesses heat dissipation features; these features allow it to operate effectively in elevated-temperature environments, and to transfer power at higher levels and/or greater distances than a typical power-transfer system. The system also might include design features to withstand mechanical shocks, stresses, and impacts for use in a rugged environment. The system can also comprise adaptations to reduce electromagnetic interference (EMI), and can comprise specially shaped components with magnetic/ferrimagnetic properties that enhance performance. Other potential features include power conditioning by combining, within one circuit or one board, multiple elements that protect against excessive current, over-voltage, and/or reverse voltage. Other features might include integration of an antenna and a battery within one module.

摘要： A wireless transmission system includes a transmitter antenna, a sensor, a demodulation circuit, and a transmitter controller. The sensor is configured to detect electrical information associated with AC wireless signals, the electrical information including, at least, a voltage of the AC wireless signals. The demodulation circuit is configured to receive the electrical information from the at least one sensor, detect a change in the electrical information, determine if the change in the electrical information meets or exceeds one of a rise threshold or a fall threshold, if the change exceeds one of the rise threshold or the fall threshold, generate an alert, and output a plurality of data alerts. The transmitter controller is configured to receive the plurality of data alerts from the demodulation circuit and decode the plurality of data alerts into the wireless data signals.

摘要： An antenna for wireless power transfer includes a first antenna portion and a second antenna portion. The first antenna portion includes a first antenna terminal, a second antenna terminal, at least one first inner turn, at least one first outer turn, and a first wire crossover electrically connecting the at least one first inner turn with the at least one second outer turn. The antenna further includes a second antenna portion including a third antenna terminal, a fourth antenna terminal, at least one second inner turn, at least one second outer turn, and a second wire crossover electrically connecting the at least one second inner turn with the at least one second outer turn. The second antenna terminal is in electrical connection with the third antenna terminal and the first antenna terminal and fourth antenna terminal are configured for electrical connection with a transmitter circuit.

摘要： Various embodiments of a multi-mode antenna are described. The antenna is preferably constructed having a first inductor coil and a second inductor coil. A plurality of shielding materials are positioned throughout the antenna to minimize interference of the magnetic fields that emanate from the coils from surrounding materials. The antenna comprises a coil control circuit having at least one of an electric filter and an electrical switch configured to modify the electrical impedance of either or both the first and second coils.
