A method for wireless energy transfer in a multipath environment includes transmitting a first energy beam with a first one of a plurality of Power Access Points (PAPs). A second energy beam is transmitted with a second PAP. A reflected beam is formed by the first energy beam reflecting from a reflective surface, wherein the first energy beam constructively interferes with the second energy beam and the reflected beam to form at least one energy bubble. A location of the at least one energy bubble is changed with a control module by adjusting a relative phase between the first energy beam and the second energy beam, wherein the location is sequentially changed to a new location to cover a space including at least one energizable device, and the energy bubble comprises an energy level enabling the energizable device to transmit a reply signal to the first PAP.

Wireless energy transfer in a multipath environment

A system for charging long-range radio frequency identification tags includes a plurality of physically separated transmitters. Each transmitter is configured to direct a respective energy beam to an energy location. A tag is at the energy location. The tag is configured to store a received energy from the energy location, to sense a sensor data and to transmit the sensor data to a reader after a capacitor connected to the tag charges to an operating voltage level. The capacitor is charged by the received energy. A controller is configured to align at the energy location for each of the plurality of transmitters, a respective frequency, and at least one of a respective phase, and a respective polarity of each respective energy beam to maximize an energy level at the energy location in response to a device response of the tag.

Charging long-range radio frequency identification tags

A method for wireless energy transfer includes forming a plurality of energy beams. Each energy beam includes one or more electromagnetic (EM) waves having a same fundamental frequency as another EM wave of another one of the energy beams. A device response of an energizable device to the plurality of energy beams incident thereon is tracked. The one or more EM waves for each of the plurality of energy beams is directed to power the energizable device. A respective phase of the one or more EM waves for at least one of the energy beams is aligned to another phase of another EM wave of another one of the energy beams. A received power level received by the energizable device is maximized according to the device response by optimizing for at least one of the energy beams, the directing, and the aligning of the phase, of the one or more EM waves.

Wireless energy transfer using alignment of electromagnetic waves

A method for improved wireless energy transfer includes steering a first energy beam, having a fundamental frequency, towards an energizable device. The first energy beam is formed by a plurality of polarizers of a first power access point (PAP). A first polarity of the first energy beam is aligned at the energizable device to a second polarity of a second energy beam formed by a second PAP, physically separate from, and having a wireless connection to, the first PAP, by combining at each of the polarizers of the first PAP a respective first polarized signal with a respective second polarized signal. The respective second polarized signal is formed by rotating the respective first polarized signal. The second PAP receives a PAP signal via the wireless connection and locally generates the fundamental frequency from the PAP signal.
