DETAILED DESCRIPTION
FIG. 1 is a diagram of an exemplary system 101 for wirelessly transferring power from a donor device to a receptor device. The donor device can be a mobile device such a laptop computer 105 and the receptor device can be a mobile device such as a mobile telephone 109. Alternatively the donor device and/or receptor device can be any mobile device such as a laptop computer, notebook computer, tablet computer, mobile phone, portable gaming system or the like. In one embodiment, a user is using a mobile phone 109 extensively throughout a day resulting in the mobile phone having low battery life. Further, the user may have to use the mobile phone 109 for an upcoming conference call and realizes that the mobile phone 109 does not have enough battery life to complete the call. However, the user has a laptop computer 105 with substantial battery life but no power supply or adapter to connect the mobile phone 109 to the laptop computer 105 to charge the mobile phone battery. Instead, according to the embodiments of the pending disclosure, a wireless power transfer mechanism 107 from the notebook computer to the mobile phone can be available to charge the mobile phone battery thereby extending the battery life to allow the user to complete the upcoming conference call.
The wireless power transfer mechanism 107 is capable of incorporating a number of technologies known in the art that include, but are not limited to, electromagnetic induction, electromagnetic radiation, and electrical conduction. Electromagnetic induction technologies include electrodynamic induction techniques such as inductive coupling as well as electrostatics induction techniques such as capacitive coupling. Electromagnetic radiation technology includes but is not limited to beamed power using radio waves, microwave transmission, and laser beaming techniques.
Inductive Coupling Wireless Power Transfer
FIG. 2A is a block diagram of an exemplary system for wirelessly transferring power from donor device to a receptor device using electromagnetic induction. Electromagnetic induction can be implemented in several different ways that includes electrodynamic induction (also called inductive coupling) and electrostatic induction (also called capacitive coupling). Generally, electromagnetic induction is the production of an electric current across a conductor moving through a magnetic field. Further, electromagnetic induction is used in the operation of generators transformers, induction motors, electric motors, synchronous motors, and solenoids.
Referring to FIG. 2A, a wireless transfer mechanism (as shown in FIG. 1) incorporates inductive coupling techniques. Further, the exemplary system for wireless transferring power includes a donor wireless power transfer mechanism (WPTM) 106 and a donor wireless power transfer mechanism 112 using electrodynamic or inductive coupling techniques. A donor WPTM 106 includes a primary coil 102 coupled to other donor WPTM circuit elements 104. Further, the donor WPTM circuit elements 104 are coupled to other donor device components 114. The primary coil 102 and the donor WPTM circuit elements 104 of the donor WPTM 106 as well as the donor device components 114 reside on a donor mobile device such as laptop computer as shown in FIG. 1.
The wireless transfer mechanism (as shown in FIG. 1) also includes a receptor WPTM 112 that has a secondary coil 108 coupled to receptor WPTM circuit elements 110. Further, the receptor WPTM circuit elements 110 are coupled to other receptor device components 118. The secondary coil 108 and the receptor WPTM circuit elements 110 of the receptor WPTM 112 as well as the donor device components 118 reside on a receptor mobile device such as mobile telephone as shown in FIG. 2A.
The primary coil 102 is driven by electric current (121 and 123) from the donor WPTM circuit elements of donor WPTM 106. Electric current (121 and 123) through the primary coil 102 generates a magnetic field 120 that surrounds secondary coil 108. The magnetic field 120 generates an electric current (125 and 127) thereby providing electric current (125 and 127) to receptor WPTM circuit elements 110 and receptor device components 118. Thus, the primary coil 102 and secondary coil 108 act similar to the coils of a power transformer that uses electromagnetic induction or inductive coupling to transfer power from a primary coil to a secondary coil.
Donor device components 114 and receptor components 118 include the battery, computer processor(s), storage devices and memory components, communication interfaces, software applications as well as other components for a mobile device as described in the pending disclosure.
Further embodiments have primary coil 102 and secondary coil 108 substantially close together due the range of the magnetic field 120 generated by the primary coil 102. Thus, in such embodiments the donor WPTM 106 and receptor WPTM 112 reside on the donor mobile device such as the laptop computer 105 in FIG. 1. Thus, the receptor device components 118 include a wire that is capable of coupling to a communication interface donor mobile device (e.g. USB, firewire, etc.) and also coupled to the receptor mobile device through a communication interface (e.g. USB, firewire, etc.) to charge the receptor battery. The charge storage device can be a rechargeable battery incorporated in a flash drive or can be one or more capacitors that can store charge for a significant amount of time. Such a charge storage device is also capable of being coupled to a receptor mobile device such as a mobile telephone 109 as shown in FIG. 1. Additional embodiments include that the donor WPTM 106 and receptor WPTM 112 both residing on the receptor mobile device. Thus, a wire coupled to the donor mobile device provides electric current through the primary coil 102 inducing a magnetic field 120 and providing electric current (125 and 127) through secondary coil 108 thereby providing power to the receptor mobile device.
Capacitive Coupling Wireless Power Transfer
FIG. 2B is a block diagram of an exemplary system 103 for wirelessly transferring power from donor device to a receptor device using capacitive coupling. The exemplary system 103 includes a donor WPTM 106 and a receptor WPTM 112. Further, the donor WPTM 106 includes donor WPTM circuit elements 104 similar to the donor WPTM circuit elements described in FIG. 2A. In addition, the donor WPTM 106 is coupled to donor device components 114 as described when discussing FIG. 1B. Moreover, the receptor WPTM 112 includes receptor WPTM circuit elements 110 similar to the receptor WPTM circuit elements described when discussing FIG. 1B. Also, the receptor WPTM 112 is coupled to receptor device components 118 as described when discussing FIG. 2A.
The donor WPTM 106 includes a primary adapter 122 and the receptor WPTM 112 includes a secondary adapter 124. The donor WPTM 106 and receptor WPTM 112 uses electrostatic induction or capacitive coupling to wirelessly transfer power from primary adapter 122 to secondary adapter 124. In one embodiment, the primary adapter 122 includes a primary conductor and the secondary adapter 124 includes a secondary conductor. Further, when the electric current (127 and 129) runs through the primary adapter 122, the primary conductor in primary adapter 122 and the secondary conductor in secondary adapter 124 along with the air between the primary conductor and secondary conductor act like a capacitor. Thus, the primary conductor and the secondary conductor act as capacitor plates and the air in between the conductors acts as a dielectric of a capacitor. Therefore, electric current (127 and 129) charges the capacitor incorporating the primary conductor and secondary conductor. Subsequently, the capacitor incorporating the primary conductor and the secondary conductor discharges and generates electric current (131 and 133) to power the receptor WPTM circuit elements 110 and receptor device components 118.
As discussed when describing FIG. 2A, the donor WPTM 106 and the receptor WPTM 112 both reside on a donor mobile device such as laptop computer 105 or in a mobile telephone 109 as shown in FIG. 1. Further, the donor WPTM 106 and the receptor WPTM 112 both reside on a charge storage device or some other USB device as described when discussing FIG. 2A.
Electromagnetic Radiation Wireless Power Transfer
FIG. 2C is a block diagram of an exemplary system 200 for wirelessly transferring power from donor device to a receptor device using electromagnetic radiation. The donor device can be a laptop computer 105 and the receptor device can be a mobile telephone 109 as shown in FIG. 1. Exemplary system 200 includes a donor wireless power transfer mechanism (WPTM) 206 having donor WPTM circuit elements 204 and a microwave (MW) or radio frequency (RF) transmitter 202. Further, the exemplary system 200 includes a receptor wireless power transfer mechanism (WPTM) 212 having receptor WPTM circuit elements 210 and a microwave or radio frequency (RF) receiver 208. In addition, donor WPTM circuit elements 204 and receptor WPTM circuit elements 210 are coupled to other donor device components 214 and receptor device components 218, respectively. Such donor and receptor device components (214 and 218) include the battery, computer processor(s), storage devices and memory components, communication interfaces, software applications as well as other components for a mobile device as described in the pending disclosure.
Donor electric current (221 and 223) powers the MW/RF transmitter 202 to emit microwave or radio frequency waves through the air 226 that are detected by the MW/RF receiver 208 on the receptor device. Further, the MW or RF waves 226 are capable of being directed by from the MW/RF transmitter 202 by a directional antenna or waveguide to the MW/RF receiver 208. Upon receiving the MW/RF waves 226, the MW/RF receiver 208 converts the energy received from the MW/RF waves 226 to receptor electric current (225 and 227) to power receptor WPTM circuit elements 210 and other receptor device components 218 such as the receptor device battery to extend battery life.
Wireless Power Transfer Using a Light Source
FIG. 2D is a block diagram of an exemplary system 201 for wirelessly transferring power from donor device to a receptor device using a light source. The donor device can be a laptop computer 105 and the receptor device can be a mobile telephone 109 as shown in FIG. 1A. Exemplary system 201 includes a donor WPTM 106 and a receptor WPTM 112. Further, the donor WPTM 206 includes donor WPTM circuit elements 204 coupled to donor device components 214. Moreover, the receptor WPTM 212 includes receptor WPTM circuit elements 210 coupled to receptor device components 218.
Further, donor WPTM 206 includes a laser transmitter 222 and collimation device 230. In addition, receptor WPTM 212 includes a photodetector 224. Electric current (229 and 231) provided by donor WPTM circuit elements 204 drive laser transmitter 222 to transmit a laser beam 228 toward photodetector 224. The collimation device 230 focuses the laser beam 228 toward the photodetector 224 so that the laser beam is not scattered away from the photodetector. Upon receiving the laser beam 228, photodetector 224 converts the received laser light energy into electric current (233 and 235) to drive receptor WPTM circuit elements 210. Further, the power is provided by the receptor WPTM circuit elements to receptor device components 218 such as the receptor battery extending battery life.
The donor WPTM circuit elements and the donor device components as well as the receptor WPTM circuit elements and receptor device components described in discussing FIGS. 2C-2D are similar to the donor WPTM circuit elements, the donor device components, receptor WPTM circuit elements and receptor device components described when discussing FIGS. 2A and 2B.
Additional embodiments include the donor device charging its own battery through its power supply coupled to an electrical power source (e.g. electrical outlet, vehicle lighter outlet, etc.) while wirelessly transferring power to a receptor device.
FIG. 3 is a block diagram of an exemplary system 300 for wirelessly transferring power from donor device such as laptop 302 to a receptor device such as a mobile telephone 304. The laptop computer 302 and mobile telephone 304 each include several components that include a central processing unit (CPU) or processors (306 and 314), memory components or storage devices (308 and 320) including removable storage media, and control software (SW) applications (310 and 318). Further, the control software applications (310 and 318) include software applications that implement software functions that assist in performing certain tasks for the laptop computer 302 and mobile telephone 304, respectively, such as providing access to a communication network, executing an operating system, managing software drivers for peripheral components, and processing information. In addition, the control software applications (310 and 318) also include software drivers for peripheral components, user interface computer programs, debugging and troubleshooting software tools. Also, the control software applications (310 and 318) include an operating system such as Droid, Symbian, IOS, Windows 7, Linux, Windows Mobile, MacOS, etc.
The laptop computer 302 wirelessly transfers power 303 to the mobile telephone 304 by one of the techniques described herein or known in the art such as inductive coupling, capacitive coupling, MW/RF radiation, and laser beam detection. Further, the laptop computer 302 includes a donor wireless power transfer mechanism and the mobile telephone 304 includes a receptor wireless power transfer mechanism as described in discussing FIGS. 1A-1C and 2A-2B. Such a donor WPTM is configured and managed by a wireless transmit software application 312 while a receptor WPTM is configured and managed by a wireless receive software application 322. The wireless transmit software application 312 and/or wireless receive software application 322 includes a function that allows a user to input a threshold (e.g. applicable to the battery life of the laptop 302 (donor power threshold) or mobile telephone 304 (receptor power threshold) to initiate wireless power transfer and continue wireless power transfer from the laptop computer 302 to mobile telephone 304 until battery of the laptop computer 302 or the mobile telephone 304 reaches the threshold (e.g. the laptop reaches a donor power threshold or the mobile telephone reaches a receptor power threshold). Alternatively, the user may enter a threshold to initiate wireless power transfer (if the laptop computer 302 and mobile telephone 304 are wirelessly coupled) when the mobile telephone battery is depleted to a threshold. The user may input such thresholds either on the laptop computer 302 and/or on the mobile telephone 304.
For example, the user configures the wireless transmit software application 312 and/or wireless receive software application 322 to manage the wireless power transfer by setting a donor power threshold for the battery life on the laptop computer. That is, the laptop computer 302 continues transferring power until the mobile telephone battery has been fully charged or that the laptop computer battery has decreased to 50% battery life. Alternatively, mobile telephone may currently have only 15% battery life. However, the user of the mobile telephone knows that an upcoming one hour conference call is capable of exhausting up to 50% of the mobile telephone's battery life. In addition, the laptop computer 302 has 95% battery life. Thus, the wireless transmit software application 312 sets a donor power threshold to continue transferring power to the mobile telephone 304 from the laptop computer 302 until the laptop computer's battery life is reduced to 45%. Alternatively, the wireless receive software application 322 sets a receptor power threshold to continue transferring power to the mobile telephone 304 from the laptop computer 302 until the mobile telephone's battery life exceeds 65%.

FIG. 4C is a block diagram 405 of an example power adapter 402 as described in discussing FIGS. 4A-4B. The power adapter 402 includes a donor WPTM 408 and a receptor WPTM 410. Further, the power adapter 402 includes a wireless transmit software application 412 and a wireless receive software application 414 that is used to configure or control donor WPTM 408 and receptor WPTM 410, respectively. In addition, the power adapter 402 includes one or more control software applications 416. The wireless transmit software application 412, wireless receive software application 414 as well as the one or more control software applications are similar to the software applications described when discussing FIG. 3.

Further, the power adapter 402 also includes communication interface 1 (422) and communication interface 2 (424) which can be USB, firewire, or any other wired or wireless communication interfaces including the hardware or software components associated with such communication interfaces (422 and 424).
Power adapter 402 incorporates electromagnetic induction or electromagnetic radiation technology as described in the pending disclosure as well as known in the art to receive and store energy from a donor device and then transmit such stored energy to a receptor device. For example, the donor WPTM 408 includes primary coil and/or a subset of the donor WPTM circuit elements and the receptor WPTM 410 includes secondary coil and/or a subset of the receptor WPTM circuit elements discussed when describing FIG. 1B thereby allowing the power adapter 402 to use electromagnetic induction to transfer energy from the donor device to the receptor device. Alternatively, the donor WPTM 408 includes primary adapter and/or a subset of the donor WPTM circuit elements and the receptor WPTM 410 includes secondary adapter and/or a subset of the receptor WPTM circuit elements discussed when describing FIG. 1C thereby allowing the power adapter 402 to use capacitive coupling to transfer energy from the donor device to the receptor device. Thus, the donor WPTM 408 and the receptor WPTM 410 includes a charge storage device such as a capacitor that is charged by current received from the donor device and subsequently discharged when coupled to the receptor device thereby potentially increasing the battery life of the receptor device.
Moreover, the donor WPTM 408 includes the microwave (MW)/radio frequency (RF) transmitter and/or a subset of the donor WPTM circuit elements and the receptor WPTM 410 includes MW/RF receiver and/or a subset of the receptor WPTM circuit elements discussed when describing FIG. 2A thereby allowing the power adapter 402 to use MW/RF radiation to transfer energy from the donor device to the receptor device. In addition, the donor WPTM 408 includes the laser transmitter as well as a collimation device and/or a subset of the donor WPTM circuit elements and the receptor WPTM 410 includes photodetector and/or a subset of the receptor WPTM circuit elements discussed when describing FIG. 2B thereby allowing the power adapter 402 to use laser beam radiation to transfer energy from the donor device to the receptor device.
The power adapter 402 includes a rechargeable battery incorporated in a flash drive or one or more capacitors that can store charge for a significant amount of time and be discharged when coupled to the receptor device thereby charging the receptor device battery and extending battery life.
FIG. 5 is a flowchart illustrating an example method 500 for wirelessly transferring power from donor device. The example method includes configuring the donor WPTM on a donor device, as shown in block 505. The donor WPTMs include the primary coil or primary adapter associated with inductive and capacitive coupling, respectively discussed when describing FIGS. 1B and 1C or microwave, RF, or laser radiation as discussed when describing FIGS. 2A and 2B.

The example method includes configuring a receptor WPTM on a receptor device, as shown in block 510. Moreover, the user configures to manage the wireless power transfer by setting a donor power threshold for the battery life on the donor device or the receptor device. That is, a laptop computer (donor device) continues transferring power until the mobile telephone (receptor device) battery has reached a receptor power threshold 85% of battery life or that the laptop computer battery has decreased to a donor power threshold of 50% battery life.
The receptor WPTMs includes the secondary coil or secondary adapter associated with inductive and capacitive coupling, respectively discussed when describing FIGS. 2A and 2B or microwave, RF, or laser radiation as discussed when describing FIGS. 2C and 2D. The configuring of the receptor WPTM is performed by a user through a wireless receive software application as discussed when describing FIG. 3.
In addition, the method includes initiating the power transfer, as shown in bock 515, which is performed by the wireless transmit software application. Further, the method includes the donor WPTM transmitting power from the donor device, as shown in block 520. The method also includes the receptor device receiving the power from the donor device, as shown in block 525. In addition, the method includes that the receptor WPTM converts the received power to electric current, as shown in block 530. The method further includes that the donor/receptor device reaches a power threshold, as shown in block 535. For example, the wireless power transfer is capable of being configured to continue until the receptor device has 95% of battery life or that the donor device battery life has decreased to 50% battery life. Upon reaching a power threshold (e.g. donor power threshold or receptor power threshold), the wireless power transfer is stopped, as shown in bock 540.

It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. 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.
