E. it is used for the bag formation method of multiple equipment

1. basic configuration

Fig. 5 shows the step of powering accoding to exemplary embodiment to multiple receiver devices.In the first step 501, Transmitter (TX) and receiver (RX) establish connection or associated.I.e. that is, transmitter and receiver can be by using Can be transmitted between two processors of electronic equipment information wireless communication protocol (for example,BLE、Wi-Fi、 NFC、) transmitting control data.For example, implementingOrIn the embodiment of modification, transmitter can be with The commercials signal or receiver of scanning radio can transmit advertising signal to transmitter.Advertising signal can be to hair The presence of machine notice receiver is penetrated, and the connection between transmitter and receiver can be triggered.As described later, In some embodiments, advertising signal can transmit can be by various equipment (for example, transmitter, client device, server meter Calculation machine, other receivers) information that uses to be to execute and manage the process of bag formation.The information for including in advertising signal can be with Including device identifier (for example, MAC Address, IP address, UUTD), the voltage of received electric energy, equipment power consumption with And other kinds of data related with electric energy transmission wave.Transmitted advertising signal can be used to identify and receive in transmitter Machine, and in some cases, the location receiver in two-dimensional space or three-dimensional space.Once transmitter identifies receiver, Then transmitter can establish connection associated with receiver in the transmitter, so that transmitter and receiver can Control signal is transmitted by the second communication channel.

As an example, when includingWhen the receiver of processor is powered on or is placed in the detection range of transmitter, Bluetooth processor can basisStandard starts to notice receiver.Transmitter can identify advertisement and begin setting up and be used for The connection of transmitting control signal and electric energy transmission signal.In some embodiments, advertising signal may include unique identifier with So that transmitter is distinguished advertisement, and finally by the receiver with it is every other in rangeEquipment distinguishes.

In next step 503, when transmitter detects advertising signal, transmitter can be automatically formed and the reception The communication connection of machine, this can enable transmitter and receivers can transmit control signal and electric energy transmission signal.Then, it sends out The machine of penetrating can order the receiver to start to transmit real-time sampling data or control data.Transmitter may also begin to transmission and come from The electric energy of the antenna of the aerial array of transmitter transmits signal.

In next step 505, receiver may then based on the received electric flux of antenna by receiver to measure Voltage and other measurements relevant to the electric energy transmission validity of signal.The control comprising metrical information can be generated in receiver Then data processed will send transmitter to comprising the control signal for controlling data.For example, receiver can be for example with per second 100 Secondary rate samples the voltage measuring value of the electric flux received.Receiver can in the form of controlling signal according to 100 times per second voltage sample measured value is sent back into transmitter.

In next step 507, transmitter can execute one or more software modules, the one or more software mould Block is monitored to from the measurement of the received such as voltage measuring value etc of receiver.Algorithm can pass through the antenna of transmitter Change the generation and transmission of electric energy transmission signal, so that the validity of the energy bag around receiver maximizes.For example, transmitting Phase when machine can transmit electric energy transmission signal to the antenna of transmitter is adjusted, until the received electric energy of receiver refers to Show the energy bag effectively established around receiver.When the best configuration for antenna is identified, the memory of transmitter can To store the configuration to keep transmitter to be propagated with highest level.

In next step 509, the algorithm of transmitter can decide when that electric energy transmission signal must be adjusted, and It can be in response to determining the configuration for needing to carry out such adjustment to change transmitter antenna.For example, transmitter can based on from The received data of receiver determine that the electric energy that receives at receiver is less than maximum value.Then, transmitter not only can be certainly The phase of dynamic adjustment electric energy transmission signal, and can continue to receive and monitor the voltage reported from receiver simultaneously.

In next step 511, after the period of the determination for communicating with specific receiver, transmitter can be swept Retouch and/or detect automatically the advertisement of other receivers in the range for being located at transmitter.Transmitter can be in response to coming from Second receiverThe connection with the second receiver is established in advertisement.

In next step 513, after establishing the second communication connection with the second receiver, transmitter can continue to adjust One or more antennas in the aerial array of whole transmitter.In some embodiments, transmitter can identify antenna subset with The second receiver is serviced, so that array is parsed into array subset associated with receiver.In some embodiments, entirely Aerial array can at a given time period in first class services receivers, then entire array can service during this period of time Second receiver.

The manually or automatically process that transmitter executes can choose a subset of array to service the second receiver.? In the example, the array of transmitter can be divided into two halves, to form two subsets.Therefore, half antenna can be configured to Electric energy is transmitted to the first receiver, and the other half antenna is configurable to transmit electric energy to the second receiver.In current step In 513, transmitter can configure using similar techniques discussed above or optimize antenna for the second receiver Collection.When selection is for transmitting an antenna subset of electric energy transmission signal, transmitter and the second receiver can transmit control Data.Therefore, when transmitter alternately communicates with the first receiver and/or scans new receiver, transmitter is had received that The sampled data of sufficient amount adjusts the phase of the wave that the second subset of the aerial array of transmitter is transmitted, thus effectively Electric energy transmission wave is transmitted to the second receiver.

In next step 515, after second subset is adjusted to transmit electric energy transmission signal to the second receiver, hair The machine of penetrating alternately can communicate or scan other receiver with the first receiver.Transmitter can reconfigure the first subset Then antenna replaces between the first receiver and the second receiver at a predetermined interval.

In next step 517, transmitter can continue to replace between receiver at a predetermined interval and scan new reception Machine.When detecting each new receiver, transmitter can establish connection, and therefore start to transmit electric energy transmission signal.

In some exemplary embodiments, receiver may be electrically connected in the equipment similar to smart phone.Transmitter Processor will scan any bluetooth equipment.It itself is a bluetooth equipment that receiver, which can begin through Bluetooth chip, which to be noticed,. In advertisement, there may be unique identifier so that transmitter is scanned at it to that can distinguish the advertisement when advertisement, finally will The receiver is distinguished with the every other bluetooth equipment in range.When transmitter detects advertisement and notices that it is to connect When receipts machine, transmitter can form the communication connection with the receiver immediately and order receiver starts to send real-time sampling number According to.

Then, receiver will measure the voltage at its receiving antenna, and voltage sample measured value is sent back transmitter (example Such as 100 times per second).Transmitter can begin through adjustment phase place to change the configuration of transmission antenna.When transmitter adjustment phase place When, transmitter monitors the voltage sent back from receiver.In some embodiments, voltage is higher, and the energy in energy bag is got over It is more.Antenna phase can be changed until voltage is in highest and there are maximum energy bags around receiver.Transmitting Antenna can be maintained at particular phases to make voltage be in the superlative degree by machine.

Transmitter can change each individual antenna, change an antenna every time.For example, if having 32 in transmitter A antenna, and each antenna has 8 phases, transmitter can will be stepped into since first antenna and by all 8 phases First antenna.Then, receiver can send back power level (power for each of 8 phases of first antenna level).Then transmitter can store the highest phase for first antenna.Transmitter can repeat this for the second antenna A process, and the second antenna is stepped by 8 phases.Receiver can send back the power level from each phase again, And transmitter can store highest level.Next, transmitter can repeat the process and continue to repeat for third antenna The process is until stepping into all 32 antennas by 8 phases.At the end of the process, transmitter can be with most effective side Maximum voltage is sent to receiver by formula.

In a further exemplary embodiment, transmitter can detecte the advertisement to the second receiver and be formed and connect with second The connection of receipts machine.When transmitter is formed with the communication of the second receiver, transmitter can make 32 original antennas aim at the Two receivers, and the phase process is repeated for 32 antennas for aiming at the second receiver.Once completing the process, second is connect Receipts machine can obtain electric energy as much as possible from transmitter.Transmitter can communicate one second with the second receiver, then exist Replace back the first receiver in predetermined time period (for example, one second), and transmitter interior at preset time intervals can continue Replace back and forth between the first receiver and the second receiver.

In yet another exemplary embodiment, transmitter can detecte the advertisement to the second receiver and be formed and connect with second The communication connection of receipts machine.Firstly, transmitter can communicate with the first receiver and redistribute the example for aiming at the first receiver Property 32 antennas in half antenna, i.e. only by 16 antenna-specifics in towards the first receiver.Then, transmitter can incite somebody to action The second half antennas in antenna distribute to the second receiver, i.e. by 16 antenna-specifics in the second receiver.Transmitter can be right The phase of the second half antennas in antenna is adjusted.Once 16 antennas experienced each of 8 phases, and second Receiver can be to obtain maximum voltage to receiver most effective way.

5. being charged using time division multiplexing to multiple equipment

Figure 51 show accoding to exemplary embodiment it is a kind of for distribute automatically the subset of aerial array with and meanwhile to two The flow chart of the method for a or more client device power supply.

When user or Systems Operator access system administration GUI by website or on the client-computing device to order When 5153 radio energies pass system to client device charging, method 5100 starts, which can connect with what is be adapted to Receipts machine matches or may include the radio energy receiver of the interior a part of hardware for being set to equipment.In other embodiments, it is Unite automatic charging scheduling can also order radio energy transmission system give client device charging.Then, system administration can be given All system transmitters send charge command 5155.Each system transmitter can be determined if in the electric energy receiver Supply district in, if the system transmitter can choose 5157 most not in the supply district of the electric energy receiver Good transmitter come control client device radio energy receiver power supply, then, selected transmitter can start with Radio energy receiver carry out real time communication come track 5159 radio energy receivers relative to transmission antenna array direction, Entire power transmitting antenna array is aimed at into radio energy receiver and starts electric energy transmission.Then, radio energy receiver can To receive the electric energy, then power to client device.

After method 5100, user or Automatic dispatching software can order 5161 to charge to the second client device, with Afterwards, selected transmitter can start to track the second radio energy with the receiver real time communication of the second client device The aerial array of transmitter is simultaneously divided into 5163 two halves by the direction of receiver, so that transmitter can aim at and use electric energy day The half of linear array or its subset to power to the first client device, aim at and using remaining antenna come to the second client End equipment power supply, so that two client devices can constantly receive electric energy.Then, judging at 5165, if User or Automatic dispatching software command give the charging of more client devices, then selected transmitter can start and third Or more client device real time communication and 5167 its antenna are redistributed by the way that the aerial array is divided into antenna subset Array is to aim at each receiver and power to each receiver.If to charge without more client devices, it is Whether system manager can will stop powering in any client device that judging that inspection is charging or powering at 5169, with Afterwards, it if stopping power supply to one or more client devices, distributes for the receiver power supply to the client device Aerial array subset 5171 can be redistributed in the receiver of remaining client device to continue to the receiver Power supply.The process is almost simultaneous for the equipment powered, this is because transmitter software is being tracked And immediately using their accurate directions relative to aerial array.If stopping charging without client device, system administration What whether device can describe before judging to check again at 5165 to have more client devices to charge and follow is synchronised Suddenly.As long as radio energy system is being given, the receiver of one or more client devices charges or power supply, this method can be after Continuous circulation carries out.

F. with the wireless power transmission of range of choice

1. constructive interference

Fig. 6 A is the exemplary system for indicating the wireless power transmission principle that can implement during illustrative bag forming process System.Transmitter 601 including the mutiple antennas in aerial array can be to the electric energy transmitted from each antenna of transmitter 601 The phase and amplitude of transmission wave 607 and other attributes are adjusted.In the case where lacking any phase or amplitude adjusts, Electric energy transmission wave 607 can be transmitted from each of antenna.In this case, due to each antenna element of transmitter Distance is located at the different distance of the receiver of each position, thus the wave transmitted will reach the different location with out of phase Place.

Receiver (RCVR) can receive multiple signal 607a from mutiple antennas element, and if these signals with Cancellation mode increases, then the combination of these signals may be substantially of zero.The antenna element of transmitter can transmit identical Electric energy transmits signal (that is, including the electric energy transmission wave with same characteristic features), however, each in electric energy transmission signal 607a It is a that receiver can be reached in a manner of being offset from one another 180 degree, thus these electric energy transmission signal can mutually " counteracting ".With The signal that this mode deviates can be referred to as " destructive interference ".On the contrary, as depicted in figure 6b, in so-called " Xiang Changgan Relate to " in, accurately " same to phase " reaches receiver to signal 607b each other, thus increases the amplitude of signal.Explanation in fig. 6 Property example in, it is noted that it is identical for transmitting the phase of signal in transmission, and they are destructively superimposed upon receiver machine Place；However, in fig. 6b, being adjusted the phase of transmission signal arrive them in a manner of phase alignment in transmission Up to receiver and constructively it is superimposed.In the illustrative embodiments, the energy around receiver will be present in Fig. 6 B Bag, and the transmission zero around receiver will be present in fig. 6.

Fig. 7 depicts the wireless power transmission 700 with range of choice, wherein transmitter 702 can produce bag formation with For multiple receivers associated with electronic equipment 701.Transmitter 702 can pass through the radio energy with range of choice Transmission 700 generates bag formation, and it may include one or more wireless chargings that this, which has the wireless power transmission 700 of range of choice, Radius 704 and the radius for being zero in one or more of specific physical location 706.It can be in wireless charging half It charges or powers to multiple electronic equipments 701 in diameter range 704.Therefore, multiple energy points can be created, these points can be used In the limitation for enabling to power and charge for electron equipment 701.As an example, the limitation may include in wireless charging half Specific electronic equipment is operated in the specific or limited point for including in diameter range 704.Furthermore, it is possible to by using having The limitation with high safety of wireless power transmission 700 of range of choice, this security restriction can be to avoid needing to avoid energy Energy bag in field or region, the field may include following field: field including the equipment sensitive to energy bag and/ Or the field of the personnel including being not intended to the energy bag near the field and/or on the field.In all realities as shown in Figure 7 It applies in the embodiment of example etc, transmitter 702 may include the receiver associated with electronic equipment 701 in service field The antenna element found in different planes.For example, the antenna element of electronic equipment 701 can be located in room, transmitter 702 may be mounted on the ceiling in the room.Can by by the aerial array of transmitter 702 be placed on ceiling or The range of choice of energy bag is established on other raised positions by using the energy transmission wave for being expressed as concentric circles, and Transmitter 702, which can issue, will generate the electric energy transmission wave of ' cone ' of energy bag.In some embodiments, transmitter 701 It can control the radius of each charging radius 704, thus to establish the interval of service field to create and be directed toward lower flat The energy bag in the field on face can adjust the width of cone by the appropriate selection to antenna phase and amplitude.

Fig. 8 depicts the wireless power transmission 800 with range of choice, and wherein transmitter 802 can produce for multiple The bag formation of receiver 806.Transmitter 802 can generate bag formation by the wireless power transmission 800 with range of choice, Wireless power transmission 800 with range of choice may include one or more wireless charging points 804.It can be in wireless charging It charges or powers to multiple electronic equipments in point 804.Energy bag can be generated in multiple receivers 806, and it is more with this is surrounded The obstacle 804 of a receiver is unrelated.It can mutually be grown according to principle described herein by creation in wireless charging point 804 Interference generates energy bag.It can be by tracking receiver 806 and by being used such as in various communication systemsSkill Multiple communication protocols such as art, infrared communication, Wi-Fi, FM radio form the position of energy bag.

G. the Exemplary System Embodiment of thermal map is used

Fig. 9 A and Fig. 9 B show accoding to exemplary embodiment for client's computing platform wireless charging framework 900A,900B.In some embodiments, user can in the room and can by electronic equipment (such as smart phone, Tablet computer) it takes.In some embodiments, electronic equipment can be located on the furniture in room.Electronic equipment can Using include be embedded into electronic equipment or as the individual adapter being connected on electronic equipment receiver 920A, 920B.Receiver 920A, 920B may include all components described in Figure 11.Transmitter 902A, 902B can be suspended on Room on a wall at user rear.Transmitter 902A, 902B also may include all portions described in Figure 11 Part.

It is difficult since user may hinder the path between receiver 920A, 920B and transmitter 902A, 902B RF wave is linearly directed at receiver 920A, 920B.However, due to the short message number generated from receiver 920A, 920B Omni-directional can be for the type of used antenna element, so these signals can be anti-on wall 944A, 944B Bullet reaches transmitter 902A, 902B until them.Hot spot 944A, 944B, which can be in room, will reflect any object of RF wave Product.For example, can be used to will be on the mobile phone of RF wave reflection to user for band large-scale metal clock on wall.

Microcontroller in transmitter is based on the signal adjusted from receiver received signal from the transmission of each antenna. Adjustment may include the conjugation (conjugates) to be formed from receiver received signal phase, and the phase of transmission antenna Adjustment also takes into account the built-in phase of antenna element.Antenna element can be controlled simultaneously along assigned direction guide energy. Transmitter 902A, 902B can scan room, and search hot spot 944A, 944B.Once calibration is performed, transmitter 902A, 902B can follow path and focus on RF wave in channel, which can be most effective path.Then, RF signal 942A, 942B can form an energy bag on the first electronic equipment, and another energy bag is formed in the second electronic equipment, The barrier of such as user and furniture etc are avoided simultaneously.When the room in scan service field, Fig. 9 A and Fig. 9 B, transmitting Different methods can be used in machine.The feasible method being able to use is limited as illustrated examples, but not, is emitted Machine can detecte the phase and amplitude of the signal from receiver, and the conjugation for example by calculating the phase and amplitude of signal And it should be used to using the phase and amplitude of the signal of the signal in transmission to form one group of transmission phase and amplitude. As another illustrated examples, transmitter can be in a manner of per next by all possible phase application of transmission antenna Into subsequent transmission, and by signal detection of the observation from receiver by each intensity for combining the energy bag formed.So Afterwards, transmitter repeats the calibration every now and then.Notice that transmitter needs not search for all possible phase but may search for base Calibration value in front of is more likely to generate one group of phase of strong energy bag.In another illustrated examples, transmitter can make The energy bag for the different location being directed toward in room is formed with the preset value of the transmission phase for antenna.For example, transmitter It can be by being scanned in room from top to bottom and from left to right in subsequent transmission using the preset phase value of antenna Physical space.Then, transmitter generates most strong energy bag by signal of the observation from receiver to detect around receiver Phase value.Without departing from spirit described herein, there are other possible methods.No matter which is used A method, the result of scanning are all the thermal map in room, in the heat map, the heat of transmitter identification instruction optimum phase and amplitude Point is to be used for transmission antenna, so that the energy bag around receiver is maximum.

Bluetooth connection can be used to determine the position of receiver 920A, 920B in transmitter 902A, 902B, and can be with RF wave is passed to different receiver 920A, 920B with different not laps using RF.In some embodiments In, the position that transmitter 902A, 902B can be scanned room to determine receiver 920A, 920B, and by not being overlapped RF transmission belt form orthogonal energy bag.Energy is directed to receiver using multiple energy bags can be inherently than one The method of electric energy transfer substituted a bit is safer, this is because very strong single transmission is not present, and received at receiver Total electric energy transmission signal is very strong.

H. Exemplary System Embodiment

Figure 10 A shows the wireless power transmission using more bag formation 1000A, which may include one A transmitter 1002A and at least two receiver 1020A.Receiver 1020A can be communicated with transmitter 1002A, this is in Figure 11 In further described.Once transmitter 1002A identification and location receiver 1020A, it will be able to be connect by knowing to come from The gain of receipts machine 1020A and phase establish channel or path.

Transmitter 1002A can start to transmit controlled RF wave 1042A, which can be by using minimum two Antenna element converges in three dimensions.By using external power supply and the local oscillations of piezoelectric material appropriate can be used Chip generates these RF waves 1042A.RF wave 1042A can be controlled by RFIC, and RFIC may include proprietary chip, this is proprietary Chip is used to be adjusted to form Xiang Changgan the phase for the RF signal that may be used as antenna element input and/relative magnitude Relate to pattern (bag formation).Bag formation can use interference and mutually grow in the antenna element to change the directionality of antenna element Interference generates energy bag 1060A, and destructive interference generates zero point.Then, receiver 1020A, which can use, passes through bag formation The energy bag that 1060A is generated charges or powers to electronic equipment (for example, laptop 1062A and smart phone 1052A), To effectively provide wireless power transmission.

It can be more to realize by calculating phase from each antenna of transmitter 1002A to receiver 1020A and gain Bag formation 1000A.Above-mentioned calculating process can be independently carried out, this is because the antenna element from transmitter 1002A can be passed through The antenna element of part to receiver 1020A generate mulitpath.

I. Exemplary System Embodiment

Figure 10 B is the example view of multiple adaptive bag formation 1000B.In this embodiment, user can be located at room In and electronic equipment can be taken, electronic equipment can be tablet computer 1064B in this case.In addition, Smart phone 1052B can be located on the furniture in room.Tablet computer 1064B and smart phone 1052B respectively may include It is embedded into each electronic equipment or as the individual adapter for being connected to tablet computer 1064B and smart phone 1052B Receiver.Receiver may include all components described in Figure 11.Transmitter 1002B can hang in a room On one wall at user rear.Transmitter 1002B can also be included in all components described in Figure 11.Since user can The path between Receiver And Transmitter 1002B can be hindered, therefore RF wave 1042B is likely difficult to take aim in a manner of along sight Quasi- each receiver.However, since the short message number generated from receiver can be full the type of used antenna element Tropism, so these signals can be rebounded on wall until they find transmitter 1002B.At substantially the same time, emitting The microcontroller being resident in machine 1002B can be based on the reception signal sent by each receiver by adjusting phase and gain And the convergence of electric energy transmission wave is formed to recalibrate transmission signal, so that they are superimposed together and enhance in the position Locate the energy concentrated, on the contrary, what is be superimposed in a manner of being subtracted from one another and make the energy reduction concentrated at the position is dry It relates to referred to as " destructive interference ", and the conjugation of the signal phase received from receiver and the adjustment general to transmission antenna The built-in phase of antenna element is taken into account.Once performing calibration, transmitter 1002B can be according to most effective path To focus RF wave.Then, energy bag 1060B can be formed on tablet computer 1064B, and another energy bag 1060B can be It is formed in smart phone 1052B, while the barrier of such as user and furniture etc being taken into account.The benefit of above-mentioned attribute It is, the wireless power transmission using multiple bag formation 1000B can be inherently safe (this is because along each energy The transmission of bag is not very strong) and RF transmission usually reflect from living tissue and the living tissue will not be penetrated.

Once transmitter 1002B identification and location receiver, it will be able to by knowing the gain from receiver 1020A Channel or path are established with phase.Transmitter 1002B can start to transport through to be converged in using minimum two antenna elements Controlled RF wave 1042B in three-dimensional space.By using external power supply and the local oscillations of piezoelectric material appropriate can be used Chip generates these RF waves 1042B.RF wave 1042B can be controlled by RFIC, and RFIC may include proprietary chip, this is proprietary Chip is used to be adjusted to form Xiang Changgan the phase for the RF signal that may be used as antenna element input and/relative magnitude Relate to pattern and destructive interference pattern (bag formation).Bag formation can use interference to change the directionality of antenna element, in the day In thread elements, constructive interference generates energy bag, and destructive interference generates transmission zero in specific physical location.Then, Receiver, which can use, fills electronic equipment (for example, laptop and smart phone) by the energy bag that bag formation generates Electricity or power supply, to effectively provide wireless power transmission.

More bag formations can be realized by calculating phase from each antenna of transmitter to receiver and gain 1000B.Above-mentioned calculating process can be independently carried out, this is because can be by from the antenna element of transmitter to receiver Antenna element generate mulitpath.

Example for the calculating of at least one antenna element may include: to determine the phase of the signal from receiver And the conjugation for receiving parameter is applied on the antenna element being used for transmission.
