`WIRELESS POWER TRANSMISSION WITH

`
`CROSS-REFERENCES TO RELATED
`APPLICATIONS
`
`The present disclosure is related to Non-Provisional patent
`application Ser. No. 13/891,430, filed May 10, 2013, entitled
`Methodology for Pocket-Forming,
`the entire content of
`which is incorporated herein by this reference.
`
`FIELD OF INVENTION
`
`The present disclosure relates to electronic transmitters.
`and more particularly to transmitters for wireless power trans-
`mission.
`
`BACKGROUND OF THE INVENTION
`
`Electronic devices such as laptop computers, smartphones,
`portable gaming devices, tablets and so forth may require
`power for performing their intended functions. This may
`require having to charge electronic equipment at least once a
`day, or in high-demand electronic devices more than once a
`day. Such an activity may be tedious and may represent a
`burden to users, For example, a user may be required to carry
`chargers in case his electronic equipment is lacking power. In
`addition, users have to find available power sources to con-
`nect to. Lastly, users must plugin to a wall or other power
`supply to be able to charge his or her electronic device.
`However, such an activity may render electronic devices
`inoperable during charging. Current solutions to this problem
`may include inductive pads which may employ magnetic
`induction or resonating coils. Nevertheless, such a solution
`may still require that electronic devices may have to be placed
`in a specific place for powering. Thus, electronic devices
`during charging may not be portable. For the foregoing rea-
`sons, there is a need for a wireless power transmission system
`where electronic devices may be powered without requiring
`extra chargers or plugs, and where the mobility and portabil-
`ity of electronic devices may not be compromised.

`The present disclosure provides various
`arrangements which can be utilized for wireless power trans-
`mission using suitable techniques such as pocket-forrning.
`Transmitters may be employed for sending Radio frequency
`(RF) signals to electronic devices which may incorporate
`receivers. Such receivers may convert RF signals into suitable
`electricity for powering and charging a plurality of electric
`devices. Wireless power transmission allows powering and
`charging a plurality of electrical devices without wires.
`A transmitter including at least two antenna elements may
`generate RF signals through the use of one or more Radio
`frequency integrated circuit (RFIC) which may be managed
`by one or more microcontrollers. Transmitters may receive
`power from a power source, which may provide enough elec-
`tricity for a subsequent conversion to RF signal.
`Wireless power transmission with selective range may be
`employed for charging or powering a plurality of electronic
`devices in a variety of spots into a variety ofranges, such spots
`may be surrounded by null-spaces where no pockets of
`energy are generated, thus, wireless power transmission may
`be used in applications Where pockets of energy are not
`desired, such applications may include sensitive equipment to
`pocket-forming or pockets of energy as well as people, who
`0007
`
`50
`

`

`

`
`do not want pockets of energy near or over them. Further-
`more, wireless power transmission with selective range may
`increase control over devices which receive charge or power,
`such control may be applied for limiting the operation area of
`certain equipment, such as, exhibition cellphones, exhibition
`tablets and any other suitable device that may be required to
`operate into a limited zone.
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`Non-limiting embodiments of the present disclosure are
`described by way of example with reference to the accompa-
`nying figures which are schematic and may not be drawn to
`scale. Unless indicated as representing the background art,
`the figures represent aspects of the disclosure.
`FIG. 1 illustrates a wireless power transmission example
`situation using pocket-forrning.
`FIG. 2 illustrates waveforms for wireless power transmis-
`sion with selective range, which may get unified in single
`waveform.
`
`FIG. 3 illustrates wireless power transmission with selec-
`tive range, where a plurality of pockets of energy may be
`generated along various radii from transmitter.
`FIG. 4 illustrates wireless power transmission with selec-
`tive range, where a plurality of pockets of energy may be

`
`DETAILED DESCRIPTION OF THE DRAWINGS
`
`“Pocket-forming” may refer to generating two or more RF
`waves which converge in 3-d space, forming controlled con-
`structive and destructive interference patterns.
`“Pockets of energy” may refer to areas or regions of space
`where energy or power may accumulate in the form of con-
`structive interference patterns of RF waves.
`“Null-space” may refer to areas or regions of space where
`pockets of energy do not form because of destructive inter-
`ference patterns of RF waves.
`“Transmitter” may refer to a device, including a chip which
`may generate two or more RF signals, at least one RF signal
`being phase shifted and gain adjusted with respect to other RF
`signals, substantially all of which pass through one or more
`RF antenna such that focused RE signals are directed to a
`target.
`“Receiver” may refer to a device including at least one
`antenna element, at least one rectifying circuit and at least one
`power converter, which may utilize pockets of energy for
`powering, or charging an electronic device.
`“Adaptive pocket-forming” may refer to dynamically
`adjusting pocket-forming to regulate power on one or more
`targeted receivers.
`
`DESCRIPTION OF THE DRAWINGS
`
`In the following detailed description, reference is made to
`the accompanying drawings, which form a part hereof. In the
`drawings, which are not to scale or to proportion, similar
`symbols typically identify similar components, unless con-
`text dictates otherwise. The
`illustrative
`embodiments
`
`described in the detailed description, drawings and claims,
`are not meant to be limiting. Other embodiments may be used
`and/or and other changes may be made without departing
`from the spirit or scope of the present disclosure.
`FIG. 1 illustrates wireless power transmission 100 using
`pocket-forrning. A transmitter 102 may transmit controlled
`Radio RF waves 104 which may converge in 3-d space. These
`Radio frequencies (RF) waves may be controlled through
`
`0007
`
`

`
`
`
`US 9,124,125 B2
`
`3
`phase and/or relative amplitude adjustments to form con-
`structive and destructive interference patterns (pocket-form-
`ing). Pockets of energy 108 may be formed at constructive
`interference patterns and can be 3-dimensional
`in shape
`whereas null-spaces may be generated at destructive interfer-
`ence patterns. A receiver 106 may then utilize pockets of
`energy 108 produced by pocket-forming for charging or pow-
`ering an electronic device, for example a laptop computer 110
`and thus effectively providing wireless power transmission.
`In other situations there can be multiple transmitters 102
`and/or multiple receivers 106 for powering various electronic
`equipment for example smartphones, tablets, music players,
`toys and others at the same time. In other embodiments,
`adaptive pocket-forming may be used to regulate power on
`electronic devices.
`
`FIG. 2 depicts a wireless power transmission principle 200,
`where two waveforms, for example waveform 202 and wave-
`form 204, as depicted in FIG. 2A may result in a unified
`waveform 206 as depicted in FIG. 2B. Such unified waveform
`206 may be generated by constructive and destructive inter-
`ference patterns between waveform 202 and waveform 204.
`As depicted in FIG. 2A, at least two waveforms with
`slightly different frequencies such as waveform 202 and
`waveform 204 may be generated at 5.7 Gigahertz (GHZ) and
`5.8 GHZ respectively. By changing the phase on one or both
`frequencies using suitable techniques such as pocket-form-
`ing, constructive and destructive interferences patterns may
`result in unified waveform 206. Unified waveform 206 may
`describe pockets of energy 108 and null-spaces along pocket-
`forming, such pockets of energy 108 may be available in
`certain areas where a constructive interference exists; such
`areas may include one or more spots which may move along
`pocket-forming trajectory and may be contained into wireless
`power range 208 X1. Wireless power range 208 X1 may
`include a minimum range and a maximum range of wireless
`power transmission 100, which may range from a few centi-
`meters to over hundreds of meters. In addition, unified wave-
`forms 206 may include several null-spaces, which may be
`available in certain areas where a destructive interference
`
`exists, such areas may include one or more null-spaces which
`may move along pocket-forming trajectory and may be con-
`tained into wireless power range 210 X2. Wireless power
`range 210 X2 may include a minimum range and a maximum
`range of wireless power transmission 100, which may range
`from a few centimeters to over hundreds of meters.

`generate pocket-forming through wireless power transmis-
`sion with selective range 400, which may include one or more
`wireless charging spots 404. A plurality of electronic devices
`may be charged or powered in wireless charging spots 404.
`Pockets of energy 108 may be generated over a plurality of
`receivers 406 regardless the obstacles 408 surrounding them,
`such effect may be produced because destructive interference
`may be generated in zones or areas where obstacles 408 are
`present. Therefore, pockets of energy 108 may be generated
`through constructive interference in wireless charging spots
`404. Location of pockets of energy 108 may be performed by
`tacking receivers 406 and by enabling a plurality of commu-
`nication protocols by a variety of communication systems
`such as, Bluetooth technology, infrared communication, WI-
`FI, FM radio among others.
`While various aspects and embodiments have been dis-
`closed herein, other aspects and embodiments may be con-
`templated. The various aspects and embodiments disclosed
`herein are for purposes of illustration and are not intended to
`be limiting, with the true scope and spirit being indicated by
`the following claims.
