Wireless power system with identifiable receiver

Abstract

This invention provides a wireless power transmission system that directs a high-energy beam to a receiver equipped with an identification marker. [Solution] One type of marker 87 may have asymmetrical shape characteristics such that its mirror image cannot match its actual shape even after being rotated, tilted, and geometrically manipulated. Multiple detectors 84 determine whether the detected image of a marker is a true image received directly from the receiver 80 or whether the beam 85 converging the image was received after being reflected between the receiver and the transmitter 81. In the latter case, the system prevents high-power transmissions from being directed to locations other than the actual receiver, thus posing a safety hazard. Other types of markers are placed in or on the boundaries of different zones in the transmission space to identify zones where transmission is permitted or prohibited.

Description

[Technical Field]

[0001] The present invention relates to the field of beam power transmission that provides energy to a remote receiver, and in particular to certification This guarantees only the direct transmission of power to the receiver, and the reception of the power transmission. Regarding the safe operation of such systems in areas where it is permissible. [Background technology]

[0002] Many wireless power systems are well known in the industry. However, in accordance with safety regulations, Over a reasonable distance from the office or process environment, often exceeding 10W Portable electronic devices such as smartphones and laptops that require charging power It appears that no commercial system exists that can transmit enough power to operate it. That is the case.

[0003] The need for wireless power transmission systems generally stems from the pioneering ideas of Nikola Tesla in the early 20th century. Since that research, it has been accepted as a long-standing necessity. Such proposed wireless Power systems rely on transmitting electromagnetic beams to solar cells or receiver antennas. Some are designed to transmit ultrasonic beams or other types of power beams to the receiver. Some are based on this.

[0004] Such suggested transmission devices are referred to as “transmitters” and “receivers” in this disclosure. A laser beam or other high-energy beam may be used to supply power to it. The "receiver" mentioned in this context is typically a device that can utilize the beam received by the transmitter. This refers to a portable electronic device equipped with a photovoltaic cell to convert energy into other forms of energy. This eliminates the need to plug the device into a physical socket, thus reducing the battery life of the device. It will be possible to charge it.

[0005] In such a system, the transmitter receives from the receiver, retroreflects the transmitted beam, and / or the receiver can be identified by receiving wireless communication from the receiver. Typically, Rooms where receivers requiring charging are expected to be found, and transmitters are broadcasting with low power settings. Using either the emitted laser beam, or a separate RF beam or ultrasonic beam It is scanned. Once the transmitter has located the receiver, the transmitter scans the mirror. —The beam can be used to direct the beam towards an identified receiver for charging purposes. .

[0006] Regarding the "wireless power distribution system" which shares common ownership and several common inventors with the present application: In Patent Document 1, an international patent publication, before enabling the transmission of all power from the transmitter, The minimum amount of energy required before the receiver can identify itself to the transmitter by giving a response. The system for transmitting to the receiver is described. Other applications are common with this application. International patent publication for "Wireless Laser Power Transmitter" owned by the same person and one common inventor In Patent Document 2, which is a report, the transmitter and receiver before full wireless power transmission can be started The system in which the handshake takes place is described.

[0007] Typically, the low power setting in search mode means that its power is below the safe limit for the human eye or Selected to remain below the regulatory safety threshold. Such limits are current as of April 2018. It is set by government regulations, such as U.S. regulations and other similarly recognized regulations. However, systems that use these safety thresholds generally take human safety into consideration. It is implemented in this context, but it is not necessarily sensitive to power beams that are considerably lower than those of the human eye. Laser beams can cause further damage to laboratory equipment, medical devices, cameras, communication systems, etc. It does not take into account other "systems" that are susceptible to this. In other words, the transmitter is low output. Even with force settings, and even for very short periods, when emitting a beam, the beam's diameter Equipment sensitive to laser beams can be damaged in the road. Therefore, such systems Identifying such sensitive devices and avoiding their scans, or all sides From a practical standpoint, the transmitter only transmits its laser oscillation to the receiver after it has identified them. It should be possible to either use a system that guarantees it can be directed. ru.

[0008] Prior art systems may suggest an unacceptable safety hazard in a given situation. There is a constant problem. The position of the receiver is known to the transmitter, and therefore the receiver and Even in systems where scanning to identify its location is not required, especially if the receiver is in a home environment When positioned within an optically complex environment such as a boundary, the beam is transmitted between the transmitter and receiver. It may be deflected or reflected by an object in the path between it and the object.

[0009] Furthermore, the low-power beam scans space, finds multiple receivers, and supplies power to them. Even in systems that attempt to be trusted, the presence and location of the receiver are not used to warn the transmitter. The size of the receiver retroreflector is only on the order of millimeters. Therefore Therefore, the search beam should have a similar or slightly larger size. If such a beam is scanned in a raster pattern or a spiral pattern, to ensure a positive position of the receiver, the distance between scan paths should be below the millimeter, which is necessary. Such a dense scan pattern would, in this case, take an overly long time. Furthermore, to ensure positive identification and logging in of the receiver, it is useful to have a high-power signal during the execution of the scan. Therefore, there is a need for a system and method that overcomes at least some of the drawbacks of the prior art and, in particular, minimizes the risk of laser oscillation in the direction of sensitive objects or in prohibited areas.

Summary of the Invention

[0013] If a wireless power transmitter misidentifies a position as a receiver, the transmitter will direct a high-energy beam at that position, which may cause damage due to the beam. For example, when an image of the receiver is reflected by a mirror, the transmitter may misidentify the reflection as the receiver and direct the beam at the image of the receiver in the mirror. This is because the beam may be reflected by the mirror. Therefore, it may trigger a dangerous reflex when directed at sensitive equipment. This reflection may cause damage or other unintended consequences. Therefore Therefore, it is important that the transmitter is given the correct position of these receivers. If directed towards an area where it is not intended, the beam emitted by the transmitter may damage people or equipment in the room. Because it can cause harm.

[0014] To address this problem, this application describes a novel receiver equipped with special or unique markings. The marker may be associated with the location of the receiver, or it may be embedded in the actual receiver. Good. A receiver that may be placed or moved at any location within the scanned space. To identify the location, the transmitter uses a camera or low-power beam, among other things, within the system. The transmitter may be used to scan the space to identify the locations of these markers. A detector is provided that identifies these codes within its field of view. This detector uses the labels This identifies the precise location of the receiver.

[0015] One important feature of the system disclosed herein is that such a marker is distinguishable from its own mirror image. That is the point. In other words, even if the surface unintentionally reflects the light from the sign, this reflection The image of the sign rendered by this method is indistinguishable from the original shape of the sign that is its mirror image. Therefore, if the system scans the room and images the reflection of the sign, the result will be The image of the sign becomes geometrically distinguishable from the original sign.

[0016] In other words, the system determines the direction of the detected reflection by detecting the reflected mirror image of the sign. It does not represent the true position of the receiver, and therefore directs the high-energy beam towards the reflected image. It is programmed to recognize that it means something that should not be done. Assuming the virtual image is in the actual direction of the actual sign, a high-power laser beam is directed towards the reflective surface. This results in the reflective surface breaking, which may lead to further control. The propagation of high-power beams into the scanning space, or the scattering of laser beams in dangerous directions. These involve disturbances or other undesirable and potentially dangerous or damaging circumstances. This is explained below. This means that the mirror or other surface that generates the reflective image of the sign is The transmitter is guaranteed not to be mistakenly identified as an actual receiver by the system. Therefore, the beam is prevented from being directed at these virtual positions of the markers on the receiver. The transmitter accurately identifies the position and arrangement of the receiver and distinguishes between the direct line of sight and the reflected beam path. They can be separated.

[0017] The detector can acquire the label display by one of the following methods. (i) A low-power beam emitted by the transmitter that is reflected by the marker and transmitted to the transmitter. The room is cleared by a low-power beam intended to be returned to the associated detector. To do, (ii) The detector is adapted to detect signals that are actively transmitted by a marker. and, (iii) from artificial or natural light sources (in the most common form), in the surrounding environment By using available ambient power or by scattering radio waves such as Wi-Fi signals Therefore, or by using other energy sources in the surroundings, the sign can be reflected. The signal being emitted, or (iv) generated by the light emitter in the receiver or reflected by the receiver Detection of any one of a series of short light pulses That is the case.

[0018] All such markings uniquely indicate either their location or orientation relative to the transmitter. It can be said that it has a special marker in that it can be used to define something. The output device receives the detected sign from the sign to the sensor or from the transmitter to the sign. Whether or not it is the result of a direct line of sight, or the result of a reflection along a path indicating a potentially dangerous situation. It is necessary to be able to determine whether or not it has been detected as such. Such determination is described in this disclosure. This is made possible by a special type of marker that can be identified by its mirror image from its direct image. This is because it is made to be effective. Therefore, images resulting from unintended reflections Therefore, it can be distinguished from directly detected images, which may result from unintended reflected beams. Appropriate safety measures can be taken due to the inherent danger. Definition and explanation of what constitutes a mirror image. Furthermore, the method for determining whether the imaged marker is a mirror image of the original marker is described below in detail. Further explanation will be provided in the explanation section.

[0019] The system of this disclosure determines operating parameters based on such identifiable special labels. To achieve this, use one of the following methods. A. When scanning the room to initially identify the receiver, part of the transmitter's field of view is, ( a) The receiver, through the reflection of power from the surroundings by its surface, for example, has a barcode. In such cases, or if the receiver generates power internally, such as by a blinking LED light source... In this case, do not use power that may be generated when the receiver is detected during scanning. (b) Safety of persons, animals, property and equipment potentially present in the System's field of view This will either use a power level within all regulations. Such scans will (i) transmit For example, the device directs lasers in different directions to assemble a "photograph" of space, and the data in each direction (ii) by collecting data, or by using a camera or other sensor (iii) The receiver itself may use a camera to transmit By taking a photograph of the, or (iv) additional components, for example, security A camera, or a dedicated camera, or other camera capable of "mapping" the room The scan can be performed either optically or externally, depending on the device. Alternatively, it can be performed by receiving potential coordinates from a pre-configured source. Typically, such scans are performed by the camera looking at the immediate vicinity, or by low-power scan lenses. By receiving communication messages from the receiver via the beam, or by the user Data input from external sources such as inputs, or the results of such scans, This can be performed by communication from an external source containing the coordinates and data being represented. In addition, ski The system is executed using radio transmission in radar-like systems, or using ultrasound. This is possible. Typically, the power level of the scan needs to be set by the user or manufacturer. Such scans can be performed at any time, but are usually performed only when requested by the user and the system is set up accordingly. This may be executed during system startup or periodically during system operation.

[0020] B. The data is integrated over the first hour. Typically, the signs are high compared to the environment. It is identified as having a thrust ratio. The system associates it with the scanned portion of the field of view. Information can be collected regarding the approximate arrangement of the receivers. In the context of this disclosure The contrast ratio used is the RMS signal when the scan beam is over the mark. This is defined as the ratio of the RMS signal when the scan beam is not on the mark. This can be done. Alternatively, the contrast ratio is the RMS value of the signal collected from one marker. The mean / representative value / arithmetic mean value collected from the same indicator, or the median signal. good.

[0021] C. If a mark is displayed, the system will examine that part of the field of view in more detail. This can be done. Typically, the obtained image is compared with an image selected from an image database. It is then compared with a marker pattern such as a barcode, and in that case, by the procedure, The resulting number has special mathematical properties, such as the remainder when divided by a large prime number. This can be checked. The observed images are rotated and cross-referenced during the comparison procedure. The size can be reduced by scaling, enlarging, or simple linear transformations. Rotation is typical. While it can be done in 3D, 2D rotation may suffice, especially in systems with a low field of view. .

[0022] The comparison image may be a set of electronic data in memory, and the comparison is like a convolution. It may be executed using any algorithm. However, other pattern matching algorithms You may use a m. Alternatively, when scanning a portion of the field of view in more detail, the marker is active. A signal may be sent to the target. As a result, the system will store the image in the image database in memory. Without the need to compare with S, or in addition to the need for such comparison, used to reliably identify the mark. It is possible.

[0023] D. When a sign is identified by a transmitter or by other elements of the system, The transmitter executes a command to modify the transmitter's operating parameters, which can be inferred. For example, if the identified marker indicates the location of the receiver, the transmitter may use that identified marker. It can begin transmitting wireless power towards a specific location.

[0024] Each sign is either a spatial pattern like a barcode, or a single sign emitted by an LED. A time pattern like a series of pulses, or a spectral space like a combination of multiple wavelengths. These may include patterns between them. These are transmitted by the transmitter, receiver, or other within the system. It can be identified by its elements and can be interpreted as numerical data.

[0025] Most signals, at least partially, are designed to transmit power from the transmitter to the receiver. Using the same wavelength as the stem, and specifically and typically the same beam... It should be possible to identify it by scanning. This is typically the location of the receiver. This includes both placement-related signs and / or safety-related signs such as receiver type. This is necessary. Numerical data can be misinterpreted from surrounding random noise patterns. The probability of coding is extremely low, typically less than once a week or less, or certain The measurement of the rate term results in a ratio of 1:1,000, 1:1,000,000, or less. It should be unique to a certain extent. Such uniqueness should be in the bits of the information received from the indicator. Therefore, it can be measured. In such cases, the indicator shall have at least 10 bits, or 20 bits. It is possible to transmit 40 or more bits of data to the transmitter.

[0026] Typical markers consist of the following methods: Structure A: High-container data such as barcodes, QR codes (registered trademarks), or other similar shapes The last optical shape is, and of particular importance, an irregular, asymmetrical shape that can be identified from the mirror image. The image may be multicolor, multiIR color, or a multiwave. A lengthy response may be provided.

[0027] Structure B: Retroreflective shape Retroreflective shapes have the advantage of being easy to detect. Retroreflective shapes are available at all wavelengths. The filter may include one that recursively reflects only the sub-sets. The retroreflective shape may also constitute areas with different reflectivity.

[0028] Structure C: Light emission shape LED lights, or patterns of LED lights, or any other light-emitting devices A unique light-emitting shape. This pattern also allows a single LED to code that can be identified by the transmitter. It can be time-dependent so that it can be generated. A laser diode can be used instead of an LED. Alternatively, phosphorescent or fluorescent structures may be used.

[0029] Structure D: RF emission "shape". A time-varying or frequency-varying signal identifiable by the transmitter. An RF emitting component (or antenna).

[0030] Structure E: At least some combinations of the above structures. The transmitter may be equipped with a marker identification system that can be matched with the laser beam system. Alternatively, the identification system can connect to the transmitter using either a wired or wireless connection. You may do so.

[0031] The label identification system may include an external aperture and a maximum range. The external aperture is typical. Specifically, it is less than 2% of the maximum range.

[0032] In the context of this disclosure, optical compatibility of the label identification system with the laser scanning system. This refers to the identification of the marker's position relative to the laser's position. This can be done using a mathematical formula or table (distance). (Modify two points upward at angles 1 and 2), or a laser beam from the mark identification system. A mapping function to at least one coordinate to the system, or a laser beam system. This may be in the form of a mapping function of at least one coordinate from to the sign recognition system. For example, in the case of a detector consisting of a CCD array, optical matching is performed in a specific range and direction. In contrast, it can be determined by a table showing the pixels that match the laser (in many cases) (The same pixel functions in different ranges). The center of the CCD field of view is at each point in space. Because they are slightly offset from the laser, different pixels can represent the laser's position. Matching means that the system includes such "transformations" from CCD / sensor images to laser coordinates. It means to do something.

[0033] Optical matching is achieved by using a laser beam with a typically rigid mechanical mount to identify the label. This can be achieved mechanically by connecting to the system, and as a result, charging the battery The optical positions of multiple sensors relative to the element are essentially fixed, or whether thermal or temporal. It has known behavior. Such connections usually require a precise rigid structure or dynamic matching. It requires the use of a method for making a decision.

[0034] Optical matching also involves positioning at least some of the sensors relative to the beam. This can be achieved optically by making it dynamically configurable based on positional measurements. For example, in the case of a position-sensitive detector, optical matching involves adding a bias to the generated signal. Set the bias on the detector so that the (or minus) signal matches the laser. This can be achieved by doing so.

[0035] Optical matching may also be achieved by algorithms.

[0036] Optical matching may also be achieved by using a combination of the methods described above.

[0037] Asymmetrical markers, by their mirror image being different from themselves, determine the receiver's position and alignment. This allows for a unique definition of sex, and furthermore, the position of the target, which is usually the center of a photovoltaic cell (PV). Determining the placement ensures that the marker is positioned in the predetermined location relative to the PV target. This is possible. However, signs are also better than retroreflectors at the center of PV. It's so much bigger that finding this sign is far more difficult than finding the center of the park. It is simple. This mark only requires a low-density scan to find, and generally, it is not very reliable. This is because it collects and reflects numbers.

[0038] The sensor rise time is the output value generated when the system is not pointed at the sign. Between the output value generated when the system is pointed at the sign and the output value generated by any sensor, This is the shortest time in which the output changes by at least 20%, preferably 50-90%. The sensor fall time is the output value generated when the system is pointed at the sign, and Between the output value generated when the stem is not pointed towards the marker and the output value generated when either sensor This is the shortest time during which the output changes by at least 20%, preferably 50-90%. Value [RMS signal] 標識関連 ] is one of the sensors when the system is pointed at the sign. This is the maximum RMS of the signal generated by [the specified method / function]. Value [RMS signal] 標識非関連 ] is either when the system is not pointed towards the sign. This is the minimum RMS of the signal generated by the sensor (typically the average across the environment). (Yes). Once time t has elapsed, preferably to a length that ensures clear identification, The signaling device determines whether a signal is a command or informational signal, or whether it is not a valid signal. It is possible.

[0039] Such signs indicate the area around the transmitter and / or the status and type of the receiver or Information can be sent to the transmitter. Such commands are typically clearly identified as receivers. Limit or modify the maximum or average laser exposure around an object that has not been exposed. This disclosure also Identification of a specific receiver, type of receiver, area for providing preferred service, exposure Additional information such as identifying unique areas like areas where emissions are reduced or areas with windows. Identifiable indicators for the report should also be included.

[0040] According to further implementation examples of the indicators described in this disclosure, the area that the transmitter intends to transmit To indicate different "zones" that represent different characteristics, signs or patterns may be used. Yes, it is possible. For example, this display is: For example, the center of a preferred charging zone can serve as a marker indicating a zone where receivers are densely concentrated. and display of range, For example, the center of a non-charging zone, such as a zone where a large number of receivers are not densely packed together. and display of range, Indication of preferred corners or edges of the charging zone, This indicates a corner or edge of a non-charging zone. The user can identify various areas by coded labels identified by the transmitter scanner. A label or contour may be defined. Such a label is a corner that the transmitter can interpret. It may be interpreted as a pivot point, center of curvature, inflection point, center of radius, or other geometric feature. Specifically, the coordinates of various domains are used to determine what actions are permitted within each defined domain. The scanner may be programmed with the relevant commands to the transmitter.

[0041] In such a system, when the transmitter detects a command indicator, the transmitter will, Typically, it works by modifying the system's configuration parameters as needed. ru.

[0042] If the detected markings are interpreted as indicators of the center and extent of the preferred charging zone, The transmitter may be configured to prefer searching for receivers within its zone, or It may supply a lot of power to the receivers in the zone, or it may provide a high advantage to the charging receivers in that zone. Priority may be assigned. Priority may be assigned to specific types of receivers, or to draw maximum power. Even more complex indicators may exist, such as prioritizing a particular receiver under specific conditions. .

[0043] If the detected indicator is interpreted as an indication of the center and extent of the non-charging zone, the transmitter This provides power to receivers within that zone, or to specific types of receivers within that zone. It may be configured to allow for the refusal of payment.

[0044] The detected markings are interpreted as markings for the corners or edges of the preferred charging zone. In this case, the receiver will define the direction and position of its preferred charging zone, as well as the other zones. It may be structured in a way that allows you to find the corner you're looking for.

[0045] If the detected sign is interpreted as an indication of a corner or edge of a non-charging zone, The receiver uses the other corners of the non-charging zone to define the direction and location of that zone. It may be structured in a way that allows you to search for something.

[0046] The detected sign was, Reduced charging speed - a zone where maximum or average power drawdown is limited. Increased charging speed - average power consumption in inaccessible areas where safety regulations may be relaxed. A zone where increasing output is acceptable. Decreased / increased scan speed - different speeds, such as in areas where the maximum achievable range is limited. Zones where receiver scans are performed at different receiver densities, Preferred zone-scan or power supply preferred zone, Reduced power zone, or Modified operating parameter zones such as high / low / specific priority zones If interpreted as a representation, The transmitter is configured to operate accordingly and operates when operating within that zone. The parameters can be changed. The detected signs are: entrance, window, mirror, mirror edge, window edge. For example, to define the center of motion, such as obstructed field of view or safety hazards, for calibration purposes. If interpreted as indicating a specific point in space, the transmitter will indicate such mark The system's operating parameters can be changed in response to the detection of recognition. For example, beam To avoid directing the beam towards the area in question, or to direct only beams with special parameters towards the area in question. To point to the rear, or any other parameter of the system when pointed in that direction It can be corrected.

[0047] The detected signs are found in high-density receiving environments such as cafes or train stations. or low-density receiver environments such as environments where a single client is known to exist. Furthermore, if interpreted as an indication of an environment having different characteristics, the transmitter movement in such environment Optimization of the process involves performing different levels of search, or searching in different ways. It can vary. Also, in many cases, transmitters in low receiver density environments will transmit The device may be configured to supply power to the receiver when it is locating the receiver. In high-density environments, the transmitter must first complete the location identification of all receivers. You can then prioritize them.

[0048] If the detected markings are interpreted as an indication of the receiver's license and legal status, The status and ID are stored in the database for special handling instructions for that receiver. It may be compared or verified against S, and based on such comparison or verification, further action The procedure may be carried out.

[0049] The detected marker indicates the location of the receiver, or is located near the receiver. If interpreted as an indication of the location of another target that can indicate direction and distance, or if Even on a device, it is possible to indicate the actual target (PV) to which the power beam should be directed. The configuration is such that the dimensions of the marker are larger than the markings on the target itself, thus affecting the receiver's position. If the time required for identification can be reduced, the system will determine the coordinates indicated by the sign. The receiver can be searched for.

[0050] The detected markings indicate the manufacturer and / or serial number and / or power capacity of the receiver and / Or, if interpreted as an indication of at least a portion of a license number, the system is typical The electronic record is updated according to the date, or the operation is based on the interpreted data. The parameters can be modified. Such operating parameters can be used to deny power to the receiver. No, the limit on the maximum power to the receiver, or the request for additional data from the receiver or other sources. , initiating payment procedures, calibrating internal sensors, providing operation-related data to receivers, or similar processes May include limitations. Operation-related data includes firmware updates, calibration data, time and date, transmission This may include data such as communication device information and geographical data.

[0051] The detected indicators are interpreted as representing client capabilities such as power requirements and usage models. If interpreted, the system will typically update its electronic records with this data. Alternatively, the system can interpret its operating parameters based on the data. It is permissible to modify it. Such changes to the operating parameters will result in the denial of power to the receiver, receiving Limitations on the maximum power of the device, requests for additional data from the receiver or other sources, opening of payment procedures Initially, the internal sensors are calibrated, and operational data is sent to the receiver, such as updates (firmware updates). This may include providing calibration data, time and date, transmitter information, geographical data, etc.

[0052] The detected sign is interpreted as indicating a temporary non-charging zone or a temporary power-restricted zone. If so, the system will remain in place until a predetermined time has elapsed or until the sign is removed. Alternatively, suspend charging for that zone until another indication is received by the system. It is possible.

[0053] The detected markers are interpreted as indicators of a certain number of targets and their relative positions. If so, the system will find those targets, and once all of those targets are found, Once the location is determined, the search for that target can be terminated.

[0054] In other words, according to a typical implementation of the device described in this disclosure, the wireless power supply device or A method is given to safely direct these beams to at least one power receiving device, The method is, (a) at least one asymmetrical feature associated with at least one power receiving device Scanning the field of view for detection by a power supply device of at least one sign having properties To do, (b) When at least one of the signs is detected, Record the scan pose from which the detected label was obtained, (c) Encompassing one or more representations of a mark associated with at least one power receiving device From the database, the marker having at least one asymmetrical characteristic is A sign that maps another detected sign to at least one of the expressions in question. Performing a matching algorithm, (d) The detected label is matched by the label matching algorithm in the database If it is determined that the detected sign matches the expression of one of the signs contained within, then the detected sign is This is presumed to indicate that the beam directed from the scan pose was not reflected. Therefore, there is no direct line of sight between the power receiving device and the wireless power supply device. What is shown, (e)(i) Direct at least one beam to the at least one power receiving device (ii) modifying the operating parameters of the wireless power supply device However, doing one of the two things Includes.

[0055] In such a method, step (e) puts the mirror image of the detected image into the database The mark mapping is performed by mapping to one of the enclosed asymmetric mark representations. The sign matching algorithm of the above method may be independent. Specifically, the mirror image of the detected image is one of the representations of the asymmetric markers included in the database. This may be done by mapping to a different parameter. In this case, the modification of the operating parameter is done by The mirror image of the detected image is mapped to one of the representations of the markers included in the database. This may include preventing wireless power supply in such cases.

[0056] In any of the above methods, step (e) is that the detected image is stored in the database. If the sign mapping algorithm determines that the included sign is not a mirror image representation. It may only be done in this case.

[0057] Further examples of the method include the (i) position, (ii) orientation and ( iii) At least one of the detected markers and scan poses It may be determined by [the relevant factor].

[0058] In all of these methods, the marker also represents different frequencies of the receiver. Zones may be described. These zones include charging zones, non-charging zones, and high-frequency receivers. It may be either a zone or a reduced power receiving zone. Additionally, these two In law, at least one of the signs is a special sign for at least one zone A feature may be defined. Such definition may include the area, range, boundary, corners, radius, and center of the zone. This may include providing information related to at least one aspect.

[0059] According to a further implementation example of the method described above, at least one marker is (i) at least (ii) may be attached to one receiver, (iii) may be embedded inside a receiver, (iii) ) may have a fixed position for at least one receiver, or (iv) at least one This may include information regarding the placement of the receivers.

[0060] Additionally, the label matching algorithm rotates and zooms the image. It may include at least one of the following.

[0061] According to other alternative implementations of the system of this disclosure, secure transmission to at least one receiver is possible. A line power supply system is further provided, and this system, (a) A transmitter adapted to emit radio power, (b) having at least one asymmetrical feature associated with at least one receiver A detector configured to detect at least one label, (c) at least one controller and Includes, This at least one controller, (i) Receiving a signal from the detector, (ii) Record the pause when the detector detects the label, (iii) A data that includes one or more representations of a marker associated with at least one receiver. Accessing a database, wherein the marker has at least one asymmetrical characteristic. to, (iv) A mark mapping that maps the detected mark to at least one expression of the expression.

[0067] A further implementation example of this invention describes a sign that provides information to a wireless power supply system. The sign is, (i) direct reflection from the sign to the radio power supply system, and (ii) from the sign The mark generated by at least one of the direct emission to the wireless power supply system The image has a symmetry property that makes it distinguishable from its mirror image. The wireless power system includes at least one sensor that detects the sign, and the The sensor determines whether the detected sign was acquired through a direct line of sight from the light sign. or whether the detected label was acquired by reflection in the laser beam path. It can be determined whether or not. In such cases, the wireless power supply system has its operating parameters Commands should be given to adjust the tactile gear according to the information provided by the detection of the sign. In this case, giving instructions means using pre-encoded instructions or instructions from a database. Received commands, or received via the network or through a wired connection It may include instructions. The sign itself contains at least one of optical data, electronic data, or electromagnetic data. It may be included.

[0068] Furthermore, the beam from the wireless power supply device is efficiently transmitted to at least one power receiving device.

[0069] In this method, the command scans the field of view associated with the detected sign. This may include, or, relating the detected indicator to the wireless power supply device. Either scan the field of view that has been blocked, or direct the beam towards that field of view. It may also include not allowing it.

Additionally, The at least one mark may have at least one asymmetrical characteristic, and the mark match The ping algorithm can distinguish between a mirror image of a marker and its original image.

[0070] Further systems of this disclosure provide efficient wireless power supply to at least one receiver. It is acceptable to provide a salary, and such a system is (a) A transmitter adapted to emit radio power, (b) In order to detect at least one marker associated with at least one zone The configured detector and (c) at least one controller and Includes, This at least one controller, (i) Receiving a signal from the detector, (ii) Record the pause when the detector detects the label, (iii) Data containing one or more representations of multiple signs associated with different zones Accessing the base and (iv) The detected label is one of at least one of the labels included in the database.

[0071] In such a system, the operation of the controller is related to the visual information associated with the detected sign. Scanning the field and sending at least one beam from the transmitter to the detected mark This may include directing it towards at least one receiver associated with it. The controller further enables wireless power supply devices to access the field of view associated with the detected marker. This includes not allowing scanning or directing the beam towards the field of view. That's fine.

[0072] In any of the methods described above, scanning is performed when the wireless power supply device emits This may be done by steering the beam, which is reflected at at least one sign. The beam is transmitted from the wireless power receiving device to the wireless power supply device, opposite to the scan beam. They move in opposite directions.

[0073] Ultimately, none of the above systems aim to detect at least one marker. It may further include a scanner adapted for scanning fields. In addition, the transmitter scans It may include a mirror. The transmitter is adapted to scan the field of view with a beam of radio power. The beam is then reflected from at least one marker and is opposite to the scan beam. It moves in that direction. In this situation, the transmitter further detects the beam that has been directed in the opposite direction. It may include a beam splitter directed towards the container. [Brief explanation of the drawing]

[0074] This invention will be more fully understood and recognized from the following detailed description in conjunction with the drawings.

[0075] [Figure 1A] A schematic example of a prior art power transmission system is shown, in which a beam collides with a reflective surface and is detected by a sensor system. [Figure 1B]A schematic example of the situation shown in Figure 1A is provided, incorporating the system described in this disclosure. The image of the receiver displayed on the reflective surface is distinguished from the image of the actual receiver that is directly visible. [Figure 2] This shows a typical room layout when the transmitter covers the entire room. Several zones are marked within the room. These include, for example, the corners of multiple zones that define areas where transmission is permitted or prohibited. [Figure 3A-3C] Figures 3A–3C show a number of examples of markers that are not useful for the novel systems of this disclosure due to their symmetry. [Figure 3D] This shows an asymmetrical marker used to determine whether the image received from the marker is a direct image or a mirror image of the marker received after reflection. [Figure 3E-3J] Figures 3E-3J show various images of the letter F, for example, to illustrate the concept of a mirror image of an object. [Figure 4] This illustrates a single marker indicating the location of more than one receiver, or more than one target on a single receiver. [Figure 5] This shows a transmitter equipped with a certain number of sensors for detecting and identifying signs, as shown above. [Figure 6] This indicates a marker that is an integral part of the receiver, asymmetrical, embedded within the receiver, and located in a fixed position relative to the photovoltaic cell. [Figure 7] This shows a barcode, an example of a high-contrast label that can encode information. [Figure 8] A typical structure of the system described in this disclosure is illustrated below. [Modes for carrying out the invention]

[0076] First, we outline an example of a prior art system that transmits optical power to a handheld mobile device. Refer to Figure 1A shown for reference. The transmitter reflects the beam off a reflective surface such as a mirror or window. Therefore, the receiver location may be incorrectly identified, posing a risk of damage to people or sensitive equipment. To increase.

[0077] In Figure 1A, the receiver 10 held by user 14 is positioned within the field of view of transmitter 11. However, the transmitter 11 receives the image 16 of the receiver 10 from the reflection of the receiver 10 itself through window 1. Since it is located within 3, the system directs the power beam 12 to the identified "receiver". "16 gives permission to transmit, believing it to be an actual receiver. The window is 9 of the incident beam If more than 0% passes through, this high power will proceed to exceed window 15, so it will pass through. Cause damage to person 15 or to sensitive equipment located along the beam path outside window 13 It is possible to surpass it.

[0078] Furthermore, the partially reflective window surface 13 cannot handle such high power levels. Therefore, it can be damaged, which in turn can cause diffuse scattering of the power beam, or even break it. In this case, the reflected beam returns to the sensor and disappears, stopping power transmission and the scan mode. A return to normal occurs. The transmitter may also accidentally direct the beam towards a reflective, flammable surface. This increases the risk of fire-related damage.

[0079] Furthermore, in systems where multiple transmitters are used, direct crossover is prevented. Even if it is a MU, the reflected beam intersects with beams emitted by different transmitters. This can happen. This can lead to unintended and even dangerous consequences. (Beam) This is because when combined, they can become more powerful than safety requirements allow. Furthermore, if the beam is accidentally When directed towards an unintended surface, the beam is diffused by that surface, and the beam enters the room. Scattering can occur. Alternatively, the surface can split the beam in random directions, affecting sensitive objects or machinery. This can also cause unintended damage to the container.

[0080] In other words, regardless of whether it is perfect reflection or partial reflection, any reflective surface, in particular, Mirrors, people, animals, and camera irises, glass surfaces, metal surfaces, and sensitive equipment are also affected by the beam's misdirection. When directed at those things, it can create a dangerous situation.

[0081] Referring now to Figure 1B, which schematically illustrates an example of an advantageous system, the transmitter is actually The light reflected or received from the receiver's position, and the virtual image of the receiver that generates an incorrect receiver position. It can accurately distinguish between the received light and the received light.

[0082] In the embodiment shown in Figure 1B, the receiver 10 is equipped with a marker 17a having an asymmetrical shape. It is provided. This allows the image of the shape to be rotated, tilted, enlarged, reduced, or cropped. Regardless of whether it is mirrored or not, it becomes possible to distinguish it from its mirror image. Transmitter 11 reflects When a reflection image of the marker 13a, which is shown as shape 17b within the window glass 17, is detected, the system The image processing routine of Tem predicts that the detected image 17b is from the actual receiver. It was determined that none of the acceptable image shapes matched, and the actual receiver was placed in that position. It accurately identifies what has not been done. The system stores the identified image in a database of labels. Compare with the received image, rotate and / or enlarge and / or tilt it. This can be done by cropping.

[0083] Alternatively, the transmitter hashs or other tables of the received image based on a predetermined algorithm. You may calculate the actual value. The database is a number associated with digital signatures, hashes, and coordinates. This may include representations of the indicator in the form of values ​​or other data representing the geometric properties of the indicator. If the image received by the device is an image of a reflected sign, then due to the asymmetry of the sign, The sign matching algorithm did not find a match, and consequently, the mirror image was not found. This means that the current sign does not exist in the database of safe signs.

[0084] In other words, the transmitter ignores the reflected image of the marker 17b and the image 17b from the reflective surface 13. To prevent dangerous transmissions, the transmitter has a direct line of sight with the marker 17a to the transmitter 11. The actual location of the receiver should be precisely identified so that beam 12 can be received directly. It can be directed towards container 10.

[0085] Here, in order to define areas that are preferred or prohibited for power transmission, how See Figure 2, which shows how recognizable signs can be used. Figure 2 covers the entire room. A typical floor plan of a room with a transmitter 23 intended for use is shown. Different zones are marked within the room. In this example, there are two charging zones 22 B, 22C, and one non-charged zone 22A are shown, and each of these zones is the zone Within the area, or to define its edge, boundary, or corner, by one or more signs It may be marked.

[0086] In other words, zone 22A has a sign 24A located at the center of the zone. It is shown. Zone 22A is a non-charging zone, which is, among other things, a sleep area. This may represent a storage area, or an area where receivers are not normally placed. The transmitter is used for identifying the marker. Therefore, the area of ​​the zone is identified, and / or the extent or surroundings of the zone are associated with the sign. Therefore, when a transmitter detects such a signal, it modifies its transmission accordingly. You will be informed of what you should do.

[0087] Zone 22B has four corners, all of which are marked 24B, 25B, 26B, and 27B. This illustrates a charging zone that can be identified by the transmitter. Identify a zone by obtaining an image of one or more markers associated with that zone. And, consequently, the area of ​​that zone is calculated, or the zone is determined based on the placement of these signs. This shows one embodiment in which the parameters and surrounding area of ​​the element can be defined.

[0088] Zone 22C includes rooms that are often conference rooms, offices, cafeterias, or rooms where receivers are typically located. It is indicated as a charging zone that can be represented. Multiple signs indicate multiple receivers placed in the room. The expected frequency and / or the predicted pattern or set in which the receiver is placed within the zone. It can represent a top-up. For example, one marker may indicate the location where a receiver is presumed to be located. This could represent a conference room that has information about a specific location on a table.

[0089] Multiple zones within circular, elliptical, or square zones of a specific size or angle. It can be marked by a single sign indicating the heart. Note that the sign is a single sign such as sign 24C. It can represent not only a 'ner' but also other types of closed shapes. Other implementation examples disclosed These may be two or more markers used to demarcate the perimeter or area of ​​the charging zone. When describing polygons in the context of this disclosure, various types of rounded corners or other Any other closed shape in two or three dimensions, such as a shape with non-acute corners and curves. Shapes may be used. Similarly, when the term "corner" is used, rounded corners may be used. A horn, or any other distinct curvature around the shape, may be mentioned.

[0090] Here, refer to Figures 3A to 3J, which show examples of the geometric properties of the markers. As a simplified example, the circular shape of the sign shown in Figure 3A represents the size of one unit ( Send the diameter of the surface and the one-dimensional spatial angular position in the direction perpendicular to its surface, indicated by the black arrow. Give it to the device.

[0091] As another simplified example, the arrow-shaped sign shown in Figure 3B represents multiple units of Size (length, width, and dimensions of the tip), and the typical size shown as the head of the black arrow in Figure 3B. The transmitter receives signals in two or three directions.

[0092] The simplified arrows shown in Figure 3C, which consist of lines rather than surfaces, are another useful indicator of such signs. This could serve as an implementation example. However, such shapes typically have low detection visibility, limiting their usefulness. ru.

[0093] Such a shape allows for the identification of the target's position relative to the sign. However, None of the shapes shown in Figures 3A, 3B, and 3C are asymmetrical. A circle is its mirror image. It is indistinguishable from the arrow, and the arrow is indistinguishable from its rotated mirror image. However, The transmitter then receives a mirror image of these markers after the beam has been reflected, and such markers It is indistinguishable from an image received directly from [the source].

[0094] Here, the optical cell 31 is placed in the receiver, depending on its position and orientation. Refer to FIG. 3D, which shows an example of an asymmetric marker 33 indicating a location on the sensor. The asymmetric marker 33 is distinguishable from its mirror image. With such a marker, the system can determine whether the marker is being viewed directly or after being reflected in a mirror. It should be noted regarding the asymmetric shape that many two-dimensional shapes, including the shape shown in FIG. 3D, can become identical to their mirror images depending on the direction in which they are viewed when rotated up to three dimensions. This occurs when the shape is viewed from the opposite side of the drawing plane of FIG. 3D, i.e., through the material containing the marker. However, in practical implementations of the present disclosure where the marker is typically attached to the surface and there is no access to the back side of the marker, the shape like that in FIG. 3D can be considered completely asymmetric in the context of the present disclosure because the marker is viewed using a camera or sensing system with a fixed field of view and the marker is imaged only from one side of the plane on which it is placed. The system can use the type of asymmetric marker shown in FIG. 3D to determine whether the received image is an image received directly from the marker or a mirror image of the marker.

Refer to FIGS. 3E - 3J, which show various images of the letter "F" as an example. The concept of the mirror image of the marker used and claimed in the present disclosure is illustrated. As shown in FIG. 3E, the original non - reflected image of the marker is in the shape of an upright capital "F". Comparing the received image with the representation of the original marker, object, or pattern being imaged requires first performing any or all of the operations of rotation, tilting, and scaling of the image as needed. Refer to FIGS. 3E - 3J, which show various images of the letter "F" as an example. The concept of the mirror image of the marker used and claimed in the present disclosure is illustrated.

[0097] As shown in FIG. 3E, the original non - reflected image of the marker is in the shape of an upright capital "F". Comparing the received image with the representation of the original marker, object, or pattern being imaged requires first performing any or all of the operations of rotation, tilting, and scaling of the image as needed. Comparing the received image with the representation of the original marker, object, or pattern being imaged requires first performing any or all of the operations of rotation, tilting, and scaling of the image as needed. Comparing the received image with the representation of the original marker, object, or pattern being imaged requires first performing any or all of the operations of rotation, tilting, and scaling of the image as needed. There is either a direct image of the original marking pattern or a cropped direct image of the original marking pattern. Before making a comparison, it may be necessary to perform rotation on one of the three coordinate axes of the 3D image. It can be done above.

[0098] The image of the detected label is rotated to the correct orientation within the two-dimensional field of view. It simply needs to be rotated 90° around the axis protruding from the plane. In addition, the original upright sentence Only horizontal expansion is necessary to obtain the letter "F," that is, the original sign pattern. .

[0099] In Figure 3F, tilting, rotating, and scaling are performed to match the image to its original pattern. It will be necessary. Therefore, the original upright letter "F", that is, the original sign pattern shown in Figure 3E During the comparison procedure, the character F appears on a plane parallel to the comparison source image. The image is tilted, then rotated until it is upright, and then its dimensions match the pattern. The size needs to be increased to this extent.

[0100] In Figure 3G, the original upright letter "F," i.e., the original sign pattern, is adapted. This may require rotation, tilting, and in some cases, scaling.

[0101] In Figure 3H, in addition to the three operations mentioned above, the original pattern from the database is also used. Rimming is required during the comparison procedure.

[0102] All of the above representations of the letter "F" are a complete match to the original pattern of the source upright letter F. It can bring about a problem.

[0103] On the other hand, with respect to the images shown in Figures 3I and 3J, rotation, tilt or It is clear that even if enlargement is performed, the original upright letter F cannot be obtained. Figures 3I and 3 The image in J is a mirror image of the original letter F. Therefore, the original upright letter "F" To obtain "", the image needs to be inverted.

[0104] The markings may consist of an asymmetrical pattern found in close proximity to the target being illuminated. The sign also has a symmetrical pattern different from its mirror image, for example, a friese pattern. It may include a line or other repeating pattern. From a point on the marker to the receiver, for more details, the receiver The direction and distance to the PV cell located inside the device are known to the transmitter from an external source. It must be, or most conveniently, encoded in the pattern itself by using a barcode. It's okay if it's not allowed.

[0105] Typically, a marker allows the transmitter to estimate the receiver's location. At least one, preferably more than one, direction and size can be determined. Typically, a marker allows the transmitter to determine the location of the receiver associated with that marker. Determining at least one, preferably more than one, direction and distance that allows for This is possible. For example, if a sign is placed on a target that is defined to be 30 mm away from the sign. It may indicate that it is present in the direction. The system can also determine the identification and distance from the transmitter. This information allows us to determine the estimated size of the sign of this shape, for example, 5 x 5 mm. For example, by searching a database, or by encoding the data of the sign itself. This allows them to be found. The signs can be seen from different ranges depending on the transmitter. , As a result, the sizes of the labels on the imaging device of the transmitter are different. However, the exact position of the target is determined by the coordinate system of the label, that is, the amount of tilt required to decode the image, in its forward, left - right, and up - down directions, and its size determined by the amount of zoom required to decode the image, and can be calculated by determining these. Once the direction of the label is known and the range and direction of the correct steps to take to reach the target on the receiver are known, the position of the target can be easily calculated.

[0106] According to another implementation example shown in FIG. 4, a single label 43 can represent the positions of more than one receiver 41 and 42, or more than one optical cell on a single receiver. Therefore, one transmitter can direct two beams to the receiver that exists at a known distance from one label, or two transmitters can be used to radiate two beams to the receiver associated with such one label. It is clear that one label can represent multiple receivers and their positions, or multiple labels can represent only a single receiver.

[0107] The label can contain other types of information. For example, the model and type of the receiver, power performance, power requirements, identification, contact address, and other types of information.

[0108] Now, refer to FIG. 5 showing a transmitter 51 equipped with a fixed number of sensors 55 for detecting and identifying such a label 53. Each one of such sensors can identify at least a part of the data encoded in the label 55, and typically interprets the data and responds accordingly. This can be transferred to a controller 52 or CPU that operates accordingly.

[0109] In most applications, one sensor is sufficient, but more than one sensor is not enough. Having this feature reduces the possibility of false detection, and generally improves the detectability of the label. Alternatively, each sensor detects the same part of the sign and compares the results for redundancy purposes. You may do so.

[0110] The sensor is part of a wireless power supply system and is embedded within the transmitter. by, or by wireless or wired connection with the transmitter, and / or both having a common control The transmitter may be connected by a roller or other device.

[0111] The receiver marking area is at least

[0112] Using larger-sized labels significantly reduces scanning time, for example, Marking the boundaries of areas where power transmission is prohibited, such as a baby's crib. In an application where a user applies a label, it becomes easier to apply the label. In a mobile device such as a mobile phone, a small-sized label can be used. It can be designed.

[0113] The transmitter typically collects information from the label during time t. t is at least

[0114] Here, refer to Figure 6 showing the marker 63. This marker is asymmetrical and embedded in the receiver 61. It is embedded. This marker is a photovoltaic cell that can be targeted by the beam emitted by the transmitter. It is located in a fixed position relative to the receiver. Such a marking positively identifies the receiver as an effective receiver. It is permissible to identify it.

[0115] Here is a diagram showing a barcode, an example of a high-contrast label that can encode information. See 7. According to one typical convention used in this disclosure, high contrast The term refers to the RMS signal when a sensor sees a portion of a label, or when the sensor sees "no label". This is understood to mean that it is at least 1.3 times larger than the RMS signal being observed. Terminology [RMS signal 標識関連 ] is optional when the system is directed towards the sign or part thereof. This is the maximum RMS of the signal generated by the sensor. Terminology [RMS signal 標識非関連 ] is when the system is not directed towards the sign, This is the minimum RMS of the signal generated by that sensor (typically the average across the environment). (This is the result).

[0116] Here, refer to Figure 8, which shows an example of a typical structure of the type of system described in this disclosure. The beam emitter 82 emits beam 85. The beam 85 is directed by the beam steering device 86. It is directed towards receiver 80 using . Marker 87 is placed on / inside the receiver, or It is associated with the location of the receiver. The source of the marker or the marker itself is an RF emitter, light emitter, or light source. It may consist of a reflector, a retroreflector, or an ultrasonic emitter.

[0117] When the transmitter scans the room with beam 85 to identify the receiver, marker 87 The signal 88 emitted from, or the signal of the sign resulting from the reflection of the incident beam from the sign. The image travels from receiver 86 to transmitter 81 in the opposite direction 88 to the search beam. Signal 88 is typically separated from the transmit beam using the beam splitter 83. The signal is directed to one or more detectors 84. The signal allows for the identification of the receiver's location. The transmitter is designed to ensure that it is a valid receiver. The transmitter first receives radio power. Before emitting the beam to initiate the process, it is necessary to clearly identify the signal emitted by the marker. There is a need for this. After positive identification of the mark, the risk of pointing the laser at a sensitive object is significantly reduced. In some cases, the transmitter can direct the beam towards the identified receiver. This ensures secure wireless power transmission.

[0118] As will be apparent to those skilled in the art, the present invention is not limited to what is specifically illustrated and described above. No. Rather, the scope of the present invention is a combination of the various features described above and subcontracts. Both binations, and modifications that a person skilled in the art could conceive of after reading the above description but which are not prior art, and Includes revised examples.
