Description

  The present invention is directed to providing an inductive power supply system. In particular, the present invention relates to the incorporation of inductive power outlets into the workspace interface.

  Providing power where and when needed is an important consideration when building a building. The number and location of power outlets required for each room depends on how the room will be used. In many cases, however, the future function of the room is not known during the construction of the room. Therefore, it is often necessary to rearrange power outlets after a long time after the building is completed, which can be costly.

  Conventional power outlets are usually placed at critical points around the walls of the room. An annular power distribution system to which power sockets are connected may be provided. Such an annular power distribution system usually extends around a conduit embedded in the wall, to which a switchboard in or on the wall is connected. Therefore, the position of the power outlet is determined by the position of the fixed switchboard. Once the walls are finished, it is difficult to rearrange the power outlets.

  To add or reposition power outlets, additional wiring must be provided. The additional wiring itself can be embedded in the wall by digging a groove in the surface of the wall, extending the wiring along the groove, and covering the wiring with gypsum, joint finish or the like. The additional power outlet is usually submerged in a recess cut into the wall, or a protruding switchboard is screwed or bolted onto the wall. Another way to reposition the power outlet is to attach a wire conduit to the outer surface of the wall, extend the wiring through the external conduit, and connect the power outlet to the external conduit. Such a solution is commonly used in schools, universities, laboratories, and other institutions, especially where the walls are made from solid stone, concrete, or blocks. This solution is understood to be costly and time consuming and unsightly.

  (Patent Document 1) given to Price describes an electrical tape and a plug connector designed to simplify and simplify installation of electrical wiring. A substantially flat or membranous conductor is sandwiched between insulating layers of protective material. The sandwich structure includes a ground conductor that is insulated from the two main current carrying conductors. One side or one side of the tape or cable is coated with a pressure sensitive adhesive. A three-pronged connector fits the tape or cable into an electrical outlet.

  In Price's solution, the wiring can be placed flat against the wall, reducing the unsightliness of the wiring and making it easier to install. However, installing a power outlet requires removing the insulation from the conductive tape and connecting a special plug. Furthermore, once the power outlet is connected, it cannot be removed without exposing the exposed conductor.

  An alternative system is described in Chang (Patent Document 2) granted to Chang. Chang describes a wire coupling device that includes one or more electrical wires that have one or more electrical cables that engage and are housed in the jacket rubber. Each of the one or more sockets has a socket housing and two conductor members secured within the socket housing, the conductor members being aligned with the socket housing orifice to receive the plug. The Each of the wires and / or sockets has an adhesive material for attachment to the surrounding wall without further fasteners. The socket may include a side opening for coupling to other wires.

  In the Chang system, the wires and outlets are affixed onto the wall surface and protrude from the wall surface. Not only is it unsightly, but if it hits a protruding socket, the socket may peel off the wall. Sockets and wires are supported only by adhesives, not additional fasteners, so if the socket is peeled off the wall, the socket will be supported only by the wires themselves, which is a safety hazard Is presented.

  Conventional electrical sockets have holes in the corresponding plug pins inserted therein to form conductive bonds. For safety, the power supply side of the coupling is generally a female part and does not have any protruding exposed conductive elements. Plugs that are coupled to this device typically have corresponding male parts with exposed pins. The size of the pins and holes is such that even a small child cannot insert a finger inside. In high-grade sockets, a ground connection is provided and the pin (or something else) is connected to the live and neutral wires that carry the current only if a plug with a longer ground pin is plugged into it. Can be inserted into the hole. Nevertheless, sometimes children unexpectedly insert pencils, pins, and other objects into the socket holes, which can sometimes be fatal. Water can also cause a short circuit and cause an electric shock.

  Because sockets are unsightly, the number of sockets installed on the wall is generally limited. In many cases, the location of the socket is not appropriate for changing requirements and an extension lead is required.

  For these and other reasons, there is a need for alternative power supplies to conventional socket outlets that are often positioned along the wall, and the present invention addresses this need.

  Reference is now made to FIG. 1, which shows a schematic diagram of a power supply system according to an exemplary embodiment of the present invention. The work space 1 such as a corner of a room delimited by the walls 2a, 2b, the ceiling 2c, and the floor 2d includes various home appliances 4 such as a television set 4a and a lighting fixture 4b. Such an appliance 4 is adapted to draw power from an inductive power outlet 6. A particular feature of one aspect of the present invention is that inductive power outlets are incorporated into the room interface 2 such as room walls, ceilings, and floors.

  With inductive power coupling, it is possible to transfer energy from the power source to the electrical load without providing a conductive path between them. The power source is connected to the primary inductor, and an oscillating potential is applied across the primary inductor to induce an oscillating magnetic field. The oscillating magnetic field can induce an oscillating current in a secondary inductor disposed in the vicinity of the primary inductor. In this way, electrical energy can be sent from the primary inductor to the secondary inductor by electromagnetic induction without electrically connecting the two inductors. This pair is said to be inductively coupled when electrical energy is sent from the primary inductor to the secondary inductor. An electrical load connected in series with such a secondary inductor can draw energy from the power source when the secondary inductor is inductively coupled to the primary inductor.

  In the inductive power outlet 6, a primary inductor 7 is connected to a power source such as a power distribution system via a controller. The controller provides the electronic circuitry necessary to drive the primary coil. Such an electronic circuit can include, for example, a switch unit that provides a high frequency oscillating voltage across the primary inductor to drive the primary inductor.

  The electrical device 4 may receive power from the inductive power outlet via a secondary inductor 5 that is configured to be inductively coupled to the primary inductor 7 of the inductive power outlet 6. As outlined in more detail below, in some embodiments of the present invention, the secondary inductor 5 may be housed in a dielectric power receiving unit wired to the electrical device 2. In other embodiments, the secondary inductor may be incorporated within the electrical device itself.

  According to various embodiments of the present invention, the inductive power outlet can be incorporated into a pre-assembled building material. Referring to FIG. 2, a gypsum board panel 100 according to one embodiment of the present invention is shown. The gypsum board panel 100 consists of a layer of building material 102, such as gypsum or the like, sandwiched between face sheets 104, 106, typically paper. Built into the gypsum board panel 100 are one or more primary inductors 108A-F and connecting lines 110, 112 that extend to the edges of the panel 100 and can be coupled to a power distribution system (not shown). .

  When bulky, primary inductors 108A-F may be embedded in building material 102. However, it is understood that the primary inductors such as induction coils 108A-F may be relatively thin and may simply be glued or affixed to the topsheet 104 designed as the exterior facing surface of the panel 100. The

  Primary inductors 108a-f and conductors 110, 112 can be made from wires or metal foils such as aluminum sheets or copper sheets. Alternatively, the primary induction coils 108a-f and the conductors 110, 112 may be printed or painted on the topsheet 104 using conductive ink.

  The magnetic flux guide core can improve electromagnetic coupling between the primary coil 108 and the secondary coil 604 (FIG. 6) disposed in the vicinity of the primary coil 108. In certain embodiments of the invention, each primary coil is associated with, for example, a flux guide core (not shown) of ferrite or amorphous ferromagnetic material, and the flux guide core is embedded in the wall material. Additional components such as ferromagnetic shield elements or the like may be further incorporated into the flux guide core.

  Referring to FIG. 3, the gypsum board panel 100 may be incorporated into the wall 200, such as a standard drywall with a gypsum board panel 202 attached to a framework 204,

  The gypsum board panel 100 can be usefully made from a “green” water-resistant gypsum board for use in a bathroom or the like. In practice, the term gypsum board is used rather broadly in this specification, especially for drywall such as other building materials, gypsum, gypsum board, gypsum flat board, seat lock, or the like. It is understood that it can also refer to things.

  Reference is now made to FIG. 4 which shows the wallpaper 300 partially unrolled. The wallpaper 300 comprises a flexible sheet 302 of laminate material, typically paper or fabric, and can be printed or patterned on the flexible sheet 302. A plurality of primary induction coils 308 are provided on the back 304 of the flexible sheet 302. The primary coil 308 can be made from a metal foil and can be glued onto the flexible sheet 302 or can comprise a conductive ink printed on the flexible sheet 302, for example by a silk screen.

  Referring to FIG. 5, the wallpaper 300 is designed to be pasted on the surface of the wall 400. Primary coil 308 is configured to inductively couple with secondary induction coil 602 (FIG. 6). Such a secondary induction coil 602 is used to provide power to a power outlet attached to the surface 402 of the wall 400 while connected to an electrical device such as a lighting fixture 460 or a television 480, for example. Or mounted on a furniture (not shown) such as a table and the like with a conventional power socket or inductive power outlet located on the wall, which may be carried by the power adapter 420 Also good.

  The power adapter 420 may be secured to the wall 400 using an adhesive or may be screwed or bolted in place. Alternatively, magnets may be embedded in the walls and magnetically coupled with corresponding magnets in power adapter 420. Preferably, the power adapter 420 is easily exchanged between different power points without the need for additional wiring. It will be appreciated that the power adapter 420 may be incorporated into an appliance such as a television, music system, or the like. It is further noted that a single appliance, such as television 480, may span across two or more primary induction coils 308, thereby allowing the appliance to draw power from more than one power point. This can be useful in a variety of charge products, such as when the power required by the appliance is greater than the power that can be supplied by a single primary induction coil 308, for example.

  Referring again to FIG. 4, the material from which the flexible sheet 302 is made usefully extends from the underlying primary induction coil 308 and the edge of the paper 300 and is coupled to a power source in the power distribution system 310, It may have a dense pattern or heavy texture to hide the underlying electrical components, such as 312.

  Optionally, the paper 300 has an adhesive surface 306 on the back surface for adhering to the wall 400. Adhesive pre-glued wallpaper itself is known, and the technology can be adapted to the inductive paper described herein. Thus, optionally, a waxy release layer or backing sheet 307, such as low density polyethylene or the like, is adhered to the adhesive layer 306. The backing sheet 307 can be peeled off so that the paper 300 can be bonded to the surface of the wall 400 or the like via the exposed adhesive surface 306. Alternatively, the front surface 301 may be coated with a waxy release material coating so that the adhesive layer 306 is easily separated by hand when rolled. Another possibility is a wallpaper paper hanger.

  Referring now to FIG. 6, in a particular embodiment of the present invention, the control box 500 is connected to the annular distribution system 540 and is required to drive the primary coil 508 embedded or adhered to the wall material 510. An electronic circuit may be provided. Drive electronics (not shown) may be provided. For example, these include a switch unit that provides a high-frequency oscillating voltage source and an outlet selector that selects a power outlet to be driven. The control box 500 may be connected to a crimp connector 520 such as a flat PCB connector, for example. Optionally, a connecting power tape 560 may be provided that does not have a primary induction coil and has a conductive strip (not shown) connecting the wall material 510 and the control box 500.

  The power adapter 600 can include a secondary induction coil 602 wired to a conventional power jack 604 that can couple a conventional power plug (not shown). Alternatively, secondary induction coil 604 may be directly connected to an electrical load such as lighting fixture 460 or the like. When the secondary induction coil 604 in the power adapter 600 is aligned with the primary induction coil 508 in the wall 510, power can be sent inductively between these coils, thereby providing power to the load. it can.

  With reference now to FIG. 7, an exemplary configuration of electrical components within a portion of a power wall 700 in accordance with another embodiment of the present invention is shown. A common conductive strip 710 connects to all primary induction coils 708 in the column. The control strip 712 consists of bundled conductors where each conductor is connected to only one primary induction coil 708. Wherever the power wall material is cut, the common conductive strip 710 and the control strip 712 can be connected to the control box 500 (FIG. 5). Thus, the control strip 712 provides a means for selectively activating each primary induction coil individually. The configuration of the electrical components described above provides control of the individual primary coils. However, it will be appreciated that alternative configurations of electrical components are possible, as will be apparent to those skilled in the art.

  Typically, plasterboard joints are covered using plastering tape before plastering the walls. Plasterer tape, usually scrim or burlap paper tape, helps maintain the integrity of the surface and reduces the risk of gypsum cracking along the joint.

  An adhesive plastering tape as described in (Patent Document 3) is known by Stoogh. The Stone tape is provided in a rolled state, helping to quickly tape the joints of adjacent drywall units. The tape has a first layer of flexible paper material having an inwardly facing pressure sensitive adhesive coating. A second layer of reinforcing fiber fabric material is overlaid on the first layer. A third layer of flexible material is overlaid on the fiber woven material to encapsulate the fiber material between the first layer and the second layer. The third layer has an outwardly facing release coating so that when wound, the first layer adhesive releasably engages the third layer to manually separate the tape. . Crees are formed along the center of the tape to facilitate positioning the tape at the center of the wall. Due to the self-releasing properties of the tape, it is possible to easily dispense and affix the tape without having to remove the backing. Adhesives have a formulation that maintains adhesion even when wet with layers of drywall mud. In addition, the third layer of the release coating allows and allows the adhesion of drywall mud such as joint finishes, gypsum, and the like.

  Reference is now made to FIG. 8a showing a roll of power outlet tape 800 incorporating an inductive power outlet 842 according to another embodiment of the present invention. The power outlet tape 800 is constructed from three layers. The first layer 820 has a pressure-sensitive adhesive surface 822 that can be adhered to a surface such as a wall. The second layer 840 holds electrical components including a series of power outlets 842 and conductive strips 844, 846. The third layer 860 overlaps the second layer 840, thereby sandwiching the electrical component between the first layer 820 and the third layer 860.

  The electrical components of the second layer 840 are conductive strips 844, 846 and a series of primary induction coils 842. Primary induction coil 842 is configured to inductively couple with a secondary induction coil carried by a power adapter that may be used to provide a power outlet on the wall.

  Preferably, the outer surface 862 of the third layer 860 is such that, when rolled, the first layer adhesive surface 822 is normally easily separated from the outer surface 862 of the third layer 860 by hand. Coated with a waxy release material coating such as low density polyethylene or the like. Alternatively, a releasable cover slip (not shown) covering the waxy release material is adhered to the adhesive layer 822 to protect the adhesive surface from collecting dust and the like, and the tape 800 is prematurely applied to the object. Do not attach.

  FIG. 8b shows an alternative embodiment of a power outlet tape 800 'comprising a two-dimensional array 840' of primary induction coils 842 '. Three rows of primary induction coils are provided, each having its own pair of conductive strips 844'a-c, 846'a-c. Note that such a roll of tape 800 'may be useful for covering large areas, such as a tabletop, work surface, and the like. Thus, an alternative power outlet tape 800 'can be used to provide a remote power point array.

  Referring to FIG. 9a, a power tape 800 being applied to the wall 900 is shown. A drywall board 920 of material such as gypsum, gypsum board, gypsum flat board, seat lock, or the like is attached to the framework 940. In order to obscure the seam 960 between adjacent drywall boards 920, segments of the power outlet tape 800 are used to bridge between adjacent drywall boards 920. Drywall board 920 and taped seam 960 create a substantially flat surface onto which gypsum 980 can be applied. Note that gypsum 980 containing a ferromagnetic material may provide additional flux guidance for inductive coupling. In the prior art, the bridging function is performed by paper, burlap, or other scrim tape that is not embedded with electrical components.

  Both ends of the power outlet tape can be connected to the control box 500 by a crimp connector 520 such as a flat PCB connector. Optionally, a connection power tape (not shown) may be provided that does not have a primary induction coil and includes a conductive strip connecting the power outlet tape 800 and the remote control box 500.

  The control box 500 connected to the annular power distribution system 540 provides an electronic circuit necessary for driving the primary induction coil 842 such as a switch unit that provides a high-frequency oscillation voltage source and an outlet selector that selects a power outlet to be driven.

  Inductive power adapters are used to provide power to wall mounted appliances as shown in FIGS. 9b and 9b. With particular reference to FIG. 9b, a wall 950 is shown that conceals two segments of power outlet tapes 810a, 810b, each having five power points that are completely plastered and each have a primary induction coil 842a-j disposed therein . Each segment 810a, 810b is connected to a justice box 500a, 500b connected to an annular power distribution system 540. Exemplary various appliance units include a single-port power adapter 420, a two-port power adapter 440, a lighting fixture power adapter 460, and a wall-mounted television 480, among others. The power adapters 420, 440, 460 can be secured to the wall using an adhesive or can be screwed in place. Alternatively, a magnet may be embedded in the wall and magnetically coupled to the magnets in adapters 420, 440, 460. Thus, power adapters 420, 440, 460 are easily exchanged between power points without the need to add any wiring.

  It will be appreciated that the power adapter may be embedded in a charge product such as a television 480, music system, or the like. A single appliance, such as the television 480 shown in FIG. 9b, extends across two or more primary induction coils 842g, 842h so that, for example, the required power is supplied by a single primary induction coil 842 when needed. Note that if greater than power, the appliance can allow power to be drawn from more than one power point.

  Referring to FIG. 9c, a diagram of inductive power adapter 600 coupled to power point 842 along a segment of power outlet tape 810 connected to control box 500 is shown. Within power adapter 600, secondary induction coil 602 is wired to a conventional power jack 604 that can be coupled to a conventional power plug. Alternatively, the secondary induction coil 604 may be connected directly to an electrical load such as a lighting fixture or the like. When the secondary induction coil 604 in the power adapter 600 is aligned with the primary induction coil 842 in the power outlet tape 800, power can be transmitted between the coils, thereby providing power to the load.

  Two embodiments of the power outlet tape are shown in FIGS. 10a and 10b. With particular reference to FIG. 10a, in a first embodiment, electrical component 840 is configured such that common conductive strip 844 connects to all primary induction coils 842 along the tape. Such a control strip 846 may consist of bundled conductors, each conductor connected to only one primary induction coil 842.

  The segment of the power outlet tape is separated from the winding, perhaps by tearing it by hand or cutting the tape using a cutting instrument such as a scissors or knife. Wherever the power outlet tape is disconnected, the common conductive strip 844 and control strip 846 may be connected to the control box 500 at that location. In this first configuration, the control strip 846 may be used to selectively activate each primary induction coil 842.

  A second embodiment of the electrical outlet tape electrical component 640 is shown in FIG. 10b. In this embodiment, each primary induction coil 642 is connected to its own dedicated conductive strip pair 644,646. The pair of conductive strips from each primary induction coil 642 is long enough to provide access to the three pairs of conductive strips along the power outlet tape and by cutting the tape along any line. Extending over. Thus, for example, by cutting the tape of the second embodiment along line A, to the conductive strip pairs 644b-d, 646b-d that control each of the subsequent three primary induction coils 642b, 642c, 642d. Contact points are provided. For example, by cutting the tape of the second embodiment along the line C, to the conductive strip pairs 644d-f, 646d-f that control each of the next three primary induction coils 642d, 642e, 642f. Contact points are provided. Only three primary induction coils are individually controllable within the power outlet tape shown here, but the number of individually controllable primary induction coils depends on the extension length of the conductive strips 644, 646. Is understood. Thus, various tapes with various conductor extension lengths that provide different numbers of individually controllable primary induction coils may be provided.

  Thus, in Reichert, which is incorporated herein by reference (Patent Document 4), electromagnetic waves are transmitted between two opposed conductors, essentially parallel conductors and parallel conductors. A heating device is described that consists of at least one heating element in the form of a flat element having a coating configured to produce. The coating material is composed of a binder, an insulating agent, a dispersant, water, and graphite. The heating device also includes a control device having a harmonic generator that includes electrical components suitable for generating harmonic components, as well as having a fast current rise. A harmonic generator is coupled to both conductors of the heating element to emit a vibration spectrum in the intrinsic molecular frequency range. Thus, a low cost and highly effective heating system is provided, and in one embodiment, the heating system is a flat panel that can be provided in a rolled form similar to wallpaper. Accordingly, flat wall mounted heating elements are known that can be incorporated into wallpaper.

  Referring again to FIG. 1, surprisingly, in addition to current induction, internal current oscillations provide an induction coil 6 or a ferromagnetic shield having a relatively high internal resistance so as to further create a heating effect. It turns out to be advantageous. Such a heating effect can be used as a convection heater to warm the room 1, and usefully an induction coil with high resistance is placed under the floor 2d or under the window, so that the room Effective thermal circulation is promoted.

  In open plan areas such as offices, factory work floors, exhibition halls, warehouses, and the like, it is often necessary to provide power to electrical devices away from walls. To avoid dragging wires, power can be provided from a socket attached to the floor or ceiling, but both of these approaches are problematic. Prior art floor-mounted plugs and cables are at risk of being kicked or struck, thereby damaging the connection and even damaging the person who is there. In this situation, it is desirable that the floor be free of power sockets and drag wires. To provide power from overhead, the cable must be lowered from the ceiling, which is unsightly and impractical when the ceiling is large, such as large balls and auditoriums, or when used outdoors without a ceiling. possible.

  Referring to FIG. 11, a solution to the above problem in which a floor-mounted inductive power outlet 1200 is connected directly to a power source (not shown) via the underfloor wiring 1220 or via a control unit (not shown). Is proposed. Primary induction coil unit 1200 is configured to be inductively coupled to secondary coil 1300 disposed thereon, and secondary coil 1300 is itself coupled to electrical loads 1320 and 1325. In this way, open floor sockets are avoided. The system 1100 described herein can be used with various types of flooring materials such as rugs, carpet covering the entire floor, parquet, linoleum, floor tiles, tiling, paving, and the like. It is understood.

  A floor mounted device 1320, such as a stand lamp 1320a or photocopier 1320b, having a secondary power coil 1300 in the base may be placed directly on the floor mounted primary coil 1200. Alternatively, furniture 1325 such as a desk 1325a or chair 1325b having a secondary coil 1300 therein is placed on the floor-mounted primary coil 1200, and an electrical device 1340 such as a desk lamp 1340a or a laptop computer 1340b or internal It can serve as a platform to provide power to a desktop appliance 1340 such as a new coffee mug 1340c that directly heats the liquid.

  Such a device 1340 may be wired to furniture 1325, plugged into a tabletop socket (not shown), or may itself include a secondary coil 1500 and interface with a primary coil 1400 on a tabletop surface 1326. May be.

  Other electrical devices that can incorporate the secondary coil 1200 for alignment with the primary coil 1200 of the system 1100 include, for example, stand lamps, televisions, music centers, video recorders, DVDs, and suitable wattages. Where available, household appliances such as washing machines, clothes dryers, and the like, and cooking appliances such as ovens, cookers, hot plates, freezers, and freezers are included. In the workplace, a system 1100 may be provided to power a floor mounted device such as a paper shredder, fan, photocopier, computer, printer, or heavy equipment.

  It is further noted that the furniture 1325 may be provided with an internally incorporated primary coil 1400 for coupling to a secondary coil 1500 associated with the workbench appliance. Examples of furniture in which such a primary coil can be embodied include a chair, a table, a work table, a partition wall, a cup board, or the like.

  Workbench appliances having an integrated secondary coil 1500 that can be aligned with a primary coil 1400 incorporated within a tabletop 1326 include, for example, desk lamps, ambient lighting units, fans, wireless phones, speakers, Speakerphone, conference call base unit, electric pencil sharpener, electric stapler, display device, electric picture frame, VDU, projector, TV, video, music center, computer, computer, scanner, printer, facsimile machine, photocopier, Examples include paper shredders, hot plates, electrically heated mugs, and mobile phones.

  There are several appliances for personal hygiene that are preferably used in bathrooms that are unobtrusive. These include shave tools, toothbrushes, hair dryers, hair curlers, and the like. Other electrical devices are also found in the bathroom, including heaters and lights. However, water and electricity should remain disconnected. Electric shock in the bathroom is really dangerous and the light switch is usually placed outside the bathroom or attached to the ceiling with a drawstring. These problems can be addressed by battery powered appliances having disposable or rechargeable batteries. However, disposable batteries are expensive and environmentally harmful. Neither disposable batteries nor rechargeable batteries are particularly reliable in that they seem to run out during work.

  The bathroom walls are ceramic tiled and the sink area is usually made of polished natural or artificial stone, stainless steel, ceramic, or polyacrylate, providing a cleanable surface that can be washed repeatedly To do. For safety, bathroom electrical sockets are usually covered with a waterproof cover. Socket sockets and switches for plug pins must be kept dry to avoid short circuits, or worse, electric shocks, so power outlet sockets should be cleaned from such work surfaces. It is understood that it is difficult.

  By providing power to the appliance via inductive coupling, the risk of electric shock in the bathroom can be minimized. In fact, some appliances can be used in a bathtub.

  Referring to FIG. 12a, a schematic diagram of an appliance such as a music player 2010 is shown. Instead of having a plug on the wire for plugging into the power outlet socket, a secondary coil 2012 is provided in the base 2014 of the appliance. The appliance 2010 can be powered by being placed on a surface 2016 such as around the sink incorporating the primary induction coil 2018 so that the secondary coil 2012 is aligned with the primary coil 2018.

  The primary coil 2018 is connected to a power supply 2019 via a driver 2017 that provides an electronic circuit necessary for driving the primary coil 2018. The drive electronics may include, for example, a switch unit that provides a high frequency oscillating voltage source.

  In addition to the music player 2010, this power supply solution includes a wide range of other appliances such as hair dryers, shavers, epilators, heaters, wax melters, hair curlers, beard trimmers, scales, televisions, radios and the like It is understood that it may be appropriate for the device. The primary coil can be hidden around a ceramic sink or behind a surface layer 2015 on a bathroom surface such as a wall tile. The primary coil may be incorporated, for example, behind a vinyl or former squid surface layer in the wall or door of a bathroom cabinet. Similarly, the primary coil is hidden under or inside the floor, such as rugs, carpet covering the entire floor, parquet, linoleum, floor tiles, tiles, paving, and the like, and electrified. The product may be placed on the floor so that it can operate without plugging in a visible power cord. Indeed, the primary coil, whether ceramic or polyacrylate, may be incorporated into the sink or bath.

  FIG. 12 b is a schematic diagram of an appliance 2210 having a secondary coil 2212 connected via an electrical wire 2211 with a vacuum suction device 2213 for attaching the secondary coil 2212 to a surface 2026 on the primary coil 2218. Primary coil 2218 is connected to power source 2219 via driver 2217.

  It is understood that preferably the bathroom surface is smooth and can be easily wiped clean. This feature allows a lightweight object to be temporarily attached to the bathroom surface 2216 using the adsorber 2213. Optionally, one or more adsorbers 2213 are provided in the vicinity of the secondary coil 2212 to mount the secondary coil 2212 on the primary coil 2218.

  Referring to FIG. 12c, sometimes the shower jet may be inadvertently directed to the lighting fixture 2310. When such lighting fixtures are powered by the distribution system, the bathroom lighting fixtures should be completely enclosed because this can lead to electric shock. It will be appreciated that a lighting fixture 2310 according to an embodiment of the present invention may be completely insulated from the power source 2302 by a dielectric material 2304 and the lighting fixture 2310 may be provided with a secondary coil 2312. The primary coil 2318 may be incorporated into, for example, a green or water resistant gypsum board 2320. Thus, an alternative safe approach to providing lighting in the bathroom is provided.

  Referring to FIG. 12d, the drawer 2400 in the bathroom cabinet 2405 is shown. The drawer 2400 is provided with one or more primary coils 2418. Indeed, its base 2404 can be covered with one large rectangular primary coil 2418 coupled to a power distribution system power supply (not shown). A plurality of rechargeable appliances such as an electric toothbrush 2424, hair dryer 2426, and shaving machine 2428 can be recharged by providing the appliance with a secondary coil (not shown) and placing it in a drawer 2400. can do.

  Referring to FIG. 12e, in addition or alternatively, a dedicated stand 2500 may be provided having a dedicated primary coil 2518 for recharging a particular appliance. For example, a toothbrush holder 2500 having a primary coil 2518 therein may be provided to recharge one or more electric toothbrushes 2524 that can be stored in the holder 2500 via a secondary coil 2512.

  Referring to FIG. 12f, a digital scale 2600 having a secondary coil 2612 underneath may be positioned on a primary coil 2618 that is embedded in the floor 2620 or placed under a bath mat (not shown).

  Thus, some embodiments of the present invention obviate the need for conventional power outlet sockets in the bathroom that are difficult to clean and inherently present a risk of electric shock.

  Certain appliances such as refrigerators, refrigerators, cooking ranges, and dishwashers tend to be plugged into dedicated sockets and are rarely moved away so that the space below and behind them can be cleaned There is no large power consuming device. Conventional electrical power technology is often useful for such devices.

  Egg whisk, bread maker, cooking mixer, orange juice squeezer, vegetable juicer, food processor, electric knife, toaster, household sterilizer, sandwich toaster, popcorn maker, magnetic stirrer, waffle maker, electric barbecue grill, throw Many other home kitchen appliances and equipment such as cookers, hot plates, deep fryer, electric frying pans, knife sharpeners, electric can openers, and the like are occasionally used, preferably with the work surface at hand. When not in use, it is stored in the cupboard so that it can be used for work.

  Ideally, such a device should be usable on any available work surface, including a drainboard beside the sink, countertop, tabletop, and the like. A well-designed kitchen in the prior art has a two-piece power outlet socket that is set in the wall on all such work surfaces, plugging in such occasional equipment, and in the desired location Make it available.

  Kitchens used to prepare food for human consumption should be kept hygienic and clean. Often, ceramic tiles are applied to the walls, and countertops are usually made of polished stone, stainless steel, or formica to provide a cleanable surface that can be washed repeatedly. Socket sockets and switches for plug pins must be kept dry to avoid short circuits or worse, electric shocks, so power outlet sockets are harder to clean than such work surfaces It is understood.

  There is a problem with water heaters in particular because they need to be replenished regularly from the water tap. For safe use, the water heater should be disconnected from the power source, and in a properly designed kitchen, the socket is not located near the sink and the water heater line is kept short. To prevent the cord attached to the plug from entering the sink (it is dangerous for the cord to enter the sink), the water heater cord can usually be disconnected at the point of connection to the water heater. However, if this connection point gets wet, there is a real danger that the short circuit and fuse will fly or trip, and it is inconvenient and even more serious the electric shock reality The danger of is avoided.

  Depending on the application, these problems may be addressed by battery powered appliances having disposable or rechargeable batteries. However, disposable batteries are expensive and environmentally harmful. Disposable batteries and rechargeable batteries are not particularly reliable in that they seem to run out of battery during work. For devices that require high power, such as water heaters and deep fryers, Battery powered is not a practical option.

  Referring to FIG. 13a, a schematic diagram of an appliance 3120, particularly a toaster, is shown. Instead of having a plug on the wire for plugging into a power outlet socket as in conventional appliances, a secondary coil 3124 is provided in its base 3122. The appliance 3120 can be powered by being placed on the work surface 3140 incorporating the primary induction coil 3144 so that the secondary coil 3124 is aligned with the primary coil 3144.

  A toaster is described here as an example, but the appliance 3120 is an egg whisk, bread maker, cooking mixer, orange juice squeezer, vegetable juicer, food processor, electric knife, sandwich toaster, waffle maker, electric barbecue grill Of a wide range of appliances or equipment, such as slow cookers, hot plates, deep fryer, electric frying pans, knife sharpeners, household sterilizers, kettles, coffee kettles, radios, cassette players, CD players, and electric can openers It will be understood that it can be any of the following.

  Primary coil 3144 is connected to power supply 3160 via a driver 3180 that provides the electronic circuitry required to drive primary coil 3144. The drive electronics may include, for example, a switch unit that provides a high frequency oscillating voltage source.

  The primary coil 3144 can be hidden behind the work top of the kitchen or the surface layer 3142 of the table. The surface layer can be, for example, a sheet of plastic, vinyl, former, or wooden veneer with an adhesive back. Similarly, primary coils are hidden behind or inside floors such as rugs, carpets covering the entire floor, parquet, linoleum, floor tiles, tiled floors, and the like, and the like Can be placed on the floor for operation.

  In a preferred embodiment, the primary coil is a polymer matrix composite containing an inorganic filler such as a solid surface building material, a resin that hardens as an artificial marble, such as Corian® or so-called Caesar (made in Israel Registered in stone. Caesar stone can be cast into sink and built-in drainage molds. Unlike actual stones that need to be drilled from behind to provide the primary induction coil near the top surface of the desired location, similar composite materials, including Caesar stone and concrete, have induction coils and connecting wires. It can be cast around inclusions such as metal objects.

  FIG. 13 b is a schematic diagram of an exemplary electrical appliance 3120, again represented by a toaster, having a secondary coil 3124 connected via a wire 3126, which operates the secondary coil 3124. There is a vacuum suction device 3128 for mounting on the secondary coil 3144 of the surface 3140.

  Similar to the embodiment of FIG. 13a, the primary coil 3144 may be incorporated into a horizontal surface 3140 such as a kitchen worktop. Alternatively, the primary coil may be behind or inside a vertical surface, such as a building or cabinet wall, e.g. inside a ceramic wall tile, behind wallpaper, behind a door or wall of a formica cupboard, or the like. Can be hidden behind.

  Preferably, the kitchen surface is smooth and can be easily wiped clean. This feature allows a lightweight object to be temporarily attached to the kitchen surface using an adsorber. Optionally, one or more adsorbers 3129 are provided for mounting the secondary coil on the primary coil.

  The appliance of FIGS. 13a and 13b may further include a socket 3128 for connecting a power cable for a conductive power source by plugging into a conventional conductive distribution system power socket.

  Alternatively, as shown in FIG. 13c, a retractable cord 3123 is provided that can be wound into the base 3122 of the appliance 3120c. Furthermore, as shown in FIG. 13c, the power storage means 3125 for storing electric power is provided to charge the apparatus so that it can be equally applied to the electric appliances 3120a and 3120b of FIGS. It can be used where it cannot. This makes the appliance according to the present invention truly portable and usable on any job.

  Here, lead-acid batteries, such as those commonly used in cars, are designed to produce high current bursts, while rechargeable batteries are essentially mobile phones, laptop computers, etc. over time Designed to power the electrical equipment. Embodiments of the present invention are directed to appliances including capacitors or electrochemical storage devices designed to provide adequate power to power an electric motor over a period of seconds to a few minutes, and thus a food processor Suitable for powering toasters, water heaters, and the like.

  Referring to FIG. 13d, a storage area 3000 such as a drawer or cupboard having a primary charging coil 3121 as a base is shown. An appliance having a rechargeable component 3125 (FIG. 13c) can be stored in storage area 3000 and removed from it for use. In this way, rechargeable component 3125 is fully charged when needed.

  In the power supply system described above, the power outlet is generally fixed at a predetermined position. According to other embodiments of the present invention, the power outlet is movable to meet changing requirements. Referring to FIG. 14a, there is shown a mobile power outlet 4100 according to another embodiment of the present invention that provides power to an electrical device, particularly a computer 4182. The primary coil 4120 is adjacent to the back surface 4142 of the surface layer 4140 and is fixed to the positioning mechanism 4160. Primary coil 4120 is configured to inductively couple to secondary coil 4180 wired to computer 4182. The positioning mechanism 4160 is configured to move the primary coil 4120 behind the surface layer 4140 so that the primary coil 4120 can be repositioned.

  Primary coil 4120 is typically connected to a power source via a controller (not shown) that provides the electronic circuitry necessary to drive primary coil 4120. The drive electronics may include, for example, a switch unit that provides a high frequency oscillating voltage source.

  In some embodiments of the present invention, the power outlet 4100 may also be incorporated in a vertical plane, such as a building or cabinet wall. The primary coil 4120 is movable behind a surface layer 4140 of, for example, wallpaper or a stretched canvas. Alternatively, the power outlet 4100 may be incorporated behind a surface layer of a horizontal platform such as a mica, formica, or wooden veneer desk, kitchen worktop, conference table, or workbench. In other embodiments, the primary coil 4120 moves under a flooring such as a rug, carpet covering the entire floor, parquet, linoleum, floor tile, tiled floor, paving, and the like. Composed.

  Referring now to FIG. 14 b, according to the first embodiment of the positioning mechanism 4160, the primary coil 4120 is sandwiched between the surface layer 4140 and the base layer 4162. Primary coil 4120 is fixed to carriage 4161 mounted on roller ball 4163 and is configured to roll on base layer 4162. A magnetic element 4166, such as iron, steel, or preferably a permanent magnet, is secured to the carriage 4161. The magnetic element 4166 is configured to be pulled by a nearby attracting magnetic element 4168 disposed on the front surface 4144 of the surface layer 4140. Moving the attracting magnetic element 4168 over the plane of the surface 4140 pulls the magnetic element 4166, thereby pulling the primary coil 4120 under the surface layer 4140 and positioning as required.

  It will be appreciated that instead of roller ball 4163, carriage 4161 may be attached to other elements such as wheels, skis, airborne magnetic elements, or the like. Where appropriate, movement of the positioning mechanism 4160 may be further aided by coating the abutment surface with a low friction material such as Teflon® (PTFE).

  In a second embodiment of the positioning mechanism 5160 as shown in FIG. 15a, the primary coil unit 5120 is slidably attached to the rail 5162. FIG. The rail 5162 may extend horizontally behind the ski 5141 on the wall 5140, for example. Primary coil unit 5120 is configured to be movable along rail 5162 to various positions. The primary coil unit 5120 can be manually pulled by a magnet, as in the embodiment of FIG. 15a. Alternatively, primary coil unit 5120 may be mounted on motorized wheel 5164 and configured to drive itself along rail 5162.

  It will be appreciated that the rail 5162 may be straight or curved, and may meander back and forth to cover a large area of the wall 5140, as shown in FIG. 15b. According to still other embodiments, two or more primary coil units 5120b may be independently positionable. Alternatively, all the primary coil units can all be moved together.

  Reference is now made to FIG. 15c, which shows a third embodiment of a positioning mechanism 5160c, in which the primary coil unit 5120 is slidably attached to the boom rail 5162, wherein the boomle rail 5162 is defined by a pair of generally vertical support tracks 5164. An adjustable H frame 5165 is formed that is slidably supported. Thereby, the position of the primary coil unit 5120 can be moved behind the surface layer 5140.

  It will be appreciated that in embodiments where the positioning mechanism 5160 is oriented vertically behind a vertical surface layer 5140, such as a wall, the support track 5164 may be replaced with a support pulley. Such a pulley can be used to support the boom rail 5162, and the boom rail 5162 can be raised and lowered by adjusting the pulley by hand or by a drive motor. Alternatively, the primary coil unit 5120 may be suspended from a pulley attached to a trolley that is configured to extend horizontally along a fixed gantry beam across the width of the wall.

  According to the fourth embodiment of the positioning mechanism 5160d as shown in FIG. 15d, the primary coil unit 5120 is fixed to the four guide cables 5162a-d. The lengths of the guide cables 5162a-d are independently controlled by pulleys 5164a-d arranged at four points that define the corners of the quadrilateral 5166. The position of the primary coil unit 5120 can be operated to an arbitrary position in the quadrilateral 5166 by the pulley 5164. Other configurations of three or more pulleys may be used to operate the primary coil unit 5120 in two dimensions, using two or even one pool, and the primary coil along the line It will be appreciated that the unit may be operated.

  Referring now to FIG. 16a, in a further embodiment of the present invention, the primary coil 6120 is inductively coupled to a secondary coil 6180 located adjacent to the back surface 6142 of the surface layer 6140 and disposed on the front surface 6142 of the surface layer 6140. Configured. The secondary coil 6180 can be connected to an electric device such as a light bulb 6184, for example.

  To maximize inductive coupling between primary coil 6120 and secondary coil 6180, the gap between the coils should be minimized. Accordingly, primary coil 6120 is preferably pressed firmly against back surface 6142 of surface layer 6140. For example, a clutch such as a compression coil spring 6122 can be provided, and the clutch biases the primary coil 6120 toward the back surface 6142. Optionally, a groove can be cut into the back plate 6142 to provide a bay 6146 with a reduced thickness of the surface layer 6140. By minimizing the thickness of the dielectric layer between the primary coil 6120 and the secondary coil 6180, the primary coil 6120 can be docked in one of these bays 6146 and efficiently inductively coupled. . For example, a wire guide core 6124 comprising a ferromagnetic material such as ferrite can be incorporated into the primary coil 6120, the secondary coil 6180, or even the surface layer 6140 to optimize inductive coupling.

  However, pressing the primary coil 6120 against the back surface 6142 increases friction between the primary coil 6120 and the back surface 6142, which may hinder the movement of the primary coil 6120. Accordingly, the release mechanism 6130 can be provided to disengage the primary coil 6120 from the back surface 6142. According to one embodiment of release mechanism 6130, primary coil 6120 is secured to the distal end of lever 6132 that is configured to pivot about connection point P with carriage 6126. A first alternative magnetic element, such as a permanent magnet 6134, is secured to the proximal end of the lever 6132 and is located near the back surface 6142 of the surface layer 6140.

  As shown in FIG. 16 b, the release mechanism 6130 is configured such that a second magnetic element 6136 that can be adjacent to the front surface 6144 of the surface layer 6140 can be positioned in the vicinity of the first magnetic element 6134. The first magnetic element 6134 is attracted toward the back surface 6142 by the second magnetic element 6136. The lever 6132 rotates around the point P, compresses the spring 6122, and causes the primary coil 6120 to disengage from the back surface 6142 of the surface layer 6140. The carriage 6126 is then free to move the primary coil 6120 to a new position as needed. Note that the first magnetic element 6134 and the second magnetic element 6136 may provide a uniqueness mechanism 6160 as described in the embodiment of FIG. 14b.

  In the case of an automated system, it is understood that a preferred embodiment of the release mechanism 6130 can include an electromagnet attached to the carriage 6126 behind the surface layer 6140. An electromagnet can be used to disengage the primary coil 6120 from the back surface 6142, thereby performing the functions of the magnetic elements 6134, 6136 described above.

  By eliminating the need for coupling pin holes, the inductive power outlets described above can be effectively hidden and are less noticeable than conventional power outlets. In general, it is advantageous that socketless outlets are less noticeable. However, the difficulty of locating than conventional power outlets has the drawback of presenting new problems to be solved. In particular, in order to use an outlet, the user must first somehow find a hidden outlet.

  The problem of finding such a socket is serious when the power outlet is behind a shielding surface such as a desk or wall and is mounted on the positioning mechanism described above. If the location of the power outlet is adjustable by being attached to a track or arm within a wall cavity or hollow work surface, and if the surface is opaque, such an indication mark on the shielding surface It is impossible to indicate the location of the power outlet.

  Referring to FIG. 17a, a localizable power outlet 7100 is shown according to another embodiment of the present invention. The localizable power outlet 7100 includes a visual display 7110 for indicating the position of the primary coil 7120 hidden behind the surface 7140, which can be incorporated into a surface 7140, such as a wall or work surface.

  Primary coil 7120 is typically connected to a power source via a controller (not shown) that provides the electronic circuitry necessary to drive primary coil 7120. The drive electronics may include, for example, a switch unit that provides a high frequency oscillating voltage source.

  According to certain embodiments of the invention, the power coil 7120 may be hidden behind a vertical surface, such as a building or cabinet wall. The primary coil 7120 can be hidden behind, for example, wallpaper or a stretched canvas surface 7140. Alternatively, the primary coil 7120 can be hidden behind a surface layer of a horizontal platform such as a mica, former, or wooden veneer desk, kitchen worktop, conference table, or workbench. In other embodiments, the primary coil 7120 is concealed under flooring such as rugs, carpeting over the entire surface, parquet, linoleum, floor tiles, tiles, paving, and the like.

  If the position of the primary coil 7120 is known, it is understood that the secondary coil 7180 can be positioned to align with the primary coil 7120 as shown in FIG. 17b. When so aligned, primary coil 7120 can be inductively coupled to secondary coil 7180, thereby supplying power to an electrical device, such as computer 7182, wired to secondary coil 7180.

  In one embodiment, the location of the hidden primary coil 7120 is indicated to the user by a visual display 7110 incorporated within the surface 7140. The visual display 7110 displays a map 7112 of the surface 7140 showing the location 7114 of the primary coil 7120.

  Reference is now made to FIG. 17c, which schematically shows a power outlet 7101 according to another embodiment of the present invention with an adjustable primary coil 7121 mounted on an adjustable H-frame 7161 and hidden behind the wall. . The adjustable primary coil 7121 can be remotely controlled from the control panel 7111, and the position of the adjustable primary coil 7121 is indicated by the position of the marker 7125 on the map 7123 represented on the control panel 7111.

  It will be appreciated that the control panel 7111 may be a touch screen where the marker 7125 is a cursor that can be moved around the visual map to control the positioning mechanism. Therefore, the marker 7125 indicates the position of the primary coil 7121 and also adjusts it. Alternatively, the control panel 7111 may be a movable mechanical switch, and the position of the switch indicates the position of the hidden primary coil 7121. An adjustable H-frame 7161 is presented here, but it will be understood that other positioning mechanisms can be applied.

  Referring now to FIG. 18a, a schematic diagram of a power outlet 8100 according to yet another embodiment of the present invention is shown. The power outlet 8100 includes a concealed primary coil 8120 that incorporates a transmitter, such as a light emitting diode 8110. A locator beam L is transmitted by the light emitting diode 8110 to indicate the position of the primary coil 8120. The surface 8140 is transparent to the wavelength emitted by the LED, so that the locator beam L can be detected by a photodiode responsive to the wavelength. It has been found that infrared radiation emitted by LEDs from behind a 0.8 mm formica sheet can be detected by standard digital cameras including, for example, digital cameras of the type incorporated in many modern mobile phones 8200. .

  Note that a thin layer 8140 of many materials, such as plastic, paperboard, former, or paper sheet, transmits infrared light. A light emitting diode 7110 that transmits light in the infrared region of the electromagnetic spectrum is invisible to the human eye, but can be easily detected by a digital camera, and such an infrared light emitting diode is incorporated in the primary coil 8120. A standard mobile phone 8200 equipped with a digital camera can serve as a detector for locating the primary coil 8120. However, if the selected cover material is transparent / translucent for a particular wavelength with the emitter radiation intensity and the thickness of the cover layer 8140, use a suitably strong visible light emitter to detect with the naked eye It is understood that it is possible to do so.

  Appropriate detectors can be selected and designated for the detection of specific electromagnetic lengths, including ultraviolet radiation, microwaves, radio waves, or even X-rays or shorter wavelengths, so that embedded electromagnetic signal emitters and detectors As long as are considered together, it is understood that there are a large number of essentially equivalent solutions to this problem. In addition, transmitters configured to transmit other types of radiation, including mechanical vibrations such as audible and non-audible sound waves (e.g., ultrasonic waves), may be concealed with appropriate corresponding detection means. May be used to identify the location of the primary coil.

  Reference is now made to FIG. 18b, which shows a block diagram representing a power outlet 8101 according to another embodiment of the present invention. Primary coil 8121 is configured to transmit a locator beam L that carries an encoded position signal S that identifies the position of primary coil 8121. The movable primary coil 8121 is connected to the power source 8112 via the switch unit 8114 and the microcontroller 8116. The switch unit 8114 is configured to intermittently connect the power source 8112 to the primary coil 8121 at the bit rate frequency f. A position monitor 8118 monitors the position of the primary coil 8121 and transmits a position signal S to the microcontroller 8116. The microcontroller 8116 is configured to modulate the bit rate signal with the position signal S. The voltage applied to the primary coil 8121 may be a modulation variable voltage having a frequency f that carries the encoded position signal S. It can be seen that the variable voltage can generate radio waves of frequency f that can be transmitted as the locator beam L. Alternatively, the locator beam L may be transmitted by a dedicated transmitter that is separate from the primary coil 8121.

  A receiver unit 8201 including a receiver 8221 may be provided. Receiver 8221 may be tuned to receive locator beam L at frequency f. The received locator beam L signal can be correlated with a reference signal of frequency f to separate the position signal S. Thereby, the position of the primary coil 8121 can be transmitted to the remote receiver unit 8201, and the remote receiver unit 8201 can then output the position of the primary coil unit to the display.

  A digital bit rate modulated locator beam L is described in the fourth embodiment, but alternatively, the locator beam L may be modulated by other methods such as analog or digital frequency modulation or amplitude modulation, for example. It is understood that

  The position monitor 8118 may monitor the position of the movable primary coil 8121 by directly tracking the movement of the primary coil 8121 relative to some reference point. Using alternative external sensors such as proximity sensors based on infrared sensors, ultrasonic sensors, magnetic sensors (such as Hall probes), inductance sensors, capacitance sensors, or the like, for example, triangulation Therefore, the movement of the primary coil 8121 may be monitored indirectly.

  High power induction outlets generate a large oscillating magnetic field when active. When the secondary inductor is inductively coupled to the primary inductor, the resulting flux link draws power into the secondary inductor. In the absence of a secondary inductor that focuses power, the oscillating magnetic field causes high-energy electromagnetic waves to be transmitted, which can be detrimental to those present in the field. Further, in low power systems, excessive heat is easily dissipated, while uncoupled high power primary coils or their surroundings can be dangerously hot.

  Thus, a block diagram of a leakage avoidance system 9000 for an inductive power outlet 9200 that can be switched on and off so that the internal primary coil 9220 generates an alternating magnetic field only when the secondary coil 9260 is positioned and draws energy is shown.

  Inductive power outlet 9200 includes a primary coil 9220 connected to a power source 9240 that is inductively coupled to a secondary coil 9260 connected to an electrical load 9264. A particular feature of this embodiment of the invention is that a circuit breaker 9280 is connected in series between the power source and the primary coil 9220 and is configured to disconnect the primary coil 9220 from the power source 9240 in operation.

  Primary coil 9220 is typically connected to power source 9240 via a driver 9230 that provides the electronic circuitry necessary to drive primary coil 9220. The drive electronics may include, for example, a switch unit that provides a high frequency oscillating voltage source. When the power outlet 9200 is composed of two or more primary coils 9220, the driver 9230 can further be composed of a selector that selects the primary coil 9220 to be driven.

  Note that circuit breaker 9280 may be connected between driver 9230 and primary coil 9220, in which case circuit breaker 9280 cuts only primary coil 9220. Alternatively, a circuit breaker may be connected between the power source 9240 and the driver 9230, in which case the circuit breaker 9280 disconnects the driver 9230 itself along with any primary coil 9220 connected to it.

  Circuit breaker 9280 typically has a primary signal P indicating that primary coil 9220 is transmitting and a secondary signal S indicating that secondary coil 9260 is inductively coupled to primary coil 9220 and drawing power from primary coil 9220. Are controlled by a controller 9400 configured to receive. The controller 9400 typically receives the primary signal P, but if the secondary signal S is not received, the controller 9400 is operable to start the circuit breaker 9280, thereby disconnecting the primary coil 9220 from the power source 9240.

  20a and 20b are schematic diagrams illustrating an inductive power outlet 9201 protected by a field leakage avoidance system 9001 according to another embodiment of the present invention. Referring specifically to FIG. 20a, the primary coil 9221 may be hidden behind a surface layer of a horizontal platform 9641, such as a desktop, kitchen worktop, conference table, or workbench. Such platforms can be made from a wide range of materials including, for example, mica, formica, or wooden veneers.

  In other embodiments, the primary coil 9221 is concealed under flooring materials and coverings such as rugs, carpet covering, parquet, linoleum, floor tiles, tiled floors, paving floors, and the like. Or can be embedded within. Alternatively, the primary coil 9221 can be embedded in or hidden behind a vertical surface such as behind a wall of a building or cabinet, such as wallpaper, a stretched canvas, or the like.

  The primary coil 9221 can be used to power an electrical device such as a computer 9262 that is wired to the secondary coil 9261, and the computer 9262 has a secondary coil 9261 coupled to the computer 9262 hidden within the platform 9641. Placed on the platform 9641 so as to be aligned with the primary coil 9221 formed.

  In a preferred embodiment of the present invention, a primary detector 9421 is disposed in the vicinity of the primary coil 9221 and is configured to detect the magnetic field generated by the primary coil 9221 that is actively transmitting power. The detector 9421 may function according to one or more of a variety of principles including magnetic sensing means, Hall probes, etc., among others. Alternatively, the detector may be a thermal or electromagnetic sensor configured to detect one or more scientific effects that are specific to or related to the operation of primary coil 9221.

  A secondary detector 9441 for detecting the presence or operation of the secondary coil 9261 is also provided. The secondary detector 9441 detects a signal indicating the presence or absence of an inductively coupled secondary coil directly or indirectly by detecting a signal from the secondary coil 9261 or from the primary coil or its surroundings. This can be done.

  The secondary detector may be a thermal detector 9441 configured to detect a large temperature increase in the platform 9441 in the vicinity of the primary coil 9221. Alternatively, the secondary detector may be a magnetic sensor, Hall probe, electromagnetic sensor, or the like configured to detect transmissions from the secondary coil 9261.

  Referring to FIG. 20a, when the secondary coil 9261 is inductively coupled to the primary coil 9221, the power sent by the primary coil 9221 is received by the secondary coil 9261 so that the electrical device 9262 is powered. A specific configuration is shown. Accordingly, the primary detector 9421 can detect the magnetic field generated by the primary coil 9221 and send a primary signal P indicating that power is being sent by the primary coil 9221 to the controller 9401. Since power is being sent to the electrical device 9262, when the secondary detector 9441 is a temperature probe, the secondary detector 9441 detects a large temperature rise, and the electrical load is primary depending on the logic programming of the controller 9401. A secondary signal S indicating that it is inductively coupled to the coil 9221 can be sent to the controller 9401 or no signal can be sent, thereby providing an equivalent indication.

  Thus, if the controller 9401 receives the primary signal P indicating that power is present in the primary coil 9221 and the secondary signal S indicating that an electrical load is present, the controller 9401 does not start the circuit breaker 9281 and does not start the primary coil 9221. Continues to draw power from the power supply 9241.

  As shown in FIG. 20b, when the secondary coil 9261 is not inductively coupled to the primary coil 9221, the power delivered by the primary coil 9221 is dissipated as heat throughout the platform 9641. The primary detector 9421 again detects the magnetic field generated by the primary coil 9221 and transmits a primary signal P indicating that the primary coil 9221 is transmitting power to the controller 9401. However, in this case, the secondary detector 9441 does not detect a large temperature rise due to heat being dissipated throughout the platform 9641, so a secondary signal indicating that the electrical load is not inductively coupled to the primary coil 9221. Send S. The controller 9401 receives a primary signal P indicating that power is being generated and a secondary signal S indicating that there is no electrical load, so that the controller 9401 starts a circuit breaker 9281, thereby causing the primary Coil 9221 is disconnected from power supply 9241 so that no further power is delivered by primary coil 9221.

  Referring now to FIG. 21, a schematic diagram is shown illustrating a plurality of inductive power outlets 9203 protected by a remote leak avoidance system 9003 according to a further embodiment of the present invention. An array of primary induction coils 9223 is incorporated in the wall 9643 and connected to a power source (not shown) via a driver 9233. Primary coil 9223 is configured to be inductively coupled with secondary coil 9263 connected to an electrical device such as a light bulb 9262 disposed in the vicinity.

  When primary coil 9223 is activated, driver 9233 provides primary coil 9223 with a variable voltage that oscillates at characteristic frequency f. Accordingly, the primary coil 9223 transmits a radio wave having a frequency f. The remote leak avoidance system 9003 includes a primary detector, such as a radio receiver 9423, that is tuned to detect radio waves of a characteristic frequency f within various ranges of the wall 9643. Such radio waves indicate that at least one primary coil 9223 is transmitting power.

  The power outlet 9203 can further include a secondary detector 9443 that detects a secondary coil 9263 that is inductively coupled to the primary coil 9223. The power transmission can then be modulated with a secondary tag indicating that secondary coil 9263 is inductively coupled to primary coil 9223.

  The primary detector 9423 can then demodulate the radio waves to identify the secondary tag. If a secondary tag is not detected, primary detector 9423 communicates to controller 9500 a control signal C that indicates that at least one primary coil 9223 is transmitting power in the absence of secondary coil 9260. According to the basic embodiment, the controller 9500 is then operable to start a circuit breaker (not shown), thereby disconnecting all primary coils 9223.

  Alternatively, driver 9233 may further include a modulator (not shown) that attaches a primary tag to each active primary coil 9223a-h power transmission that uniquely identifies the active primary coil 9223a-h that is the source of the radio wave. . Next, primary detector 9423 detects the primary tag, thereby identifying which defective primary coil is transmitting power in the absence of a secondary coil. Next, the primary detector 9423 communicates this to the controller 9500, which cuts only the defective primary coil.

A method for preventing the inductive power outlet of the embodiment of the present invention from transmitting power in the absence of a combined electrical load is presented in the flowchart of FIG. This method has the following steps:
a) the primary coil transmitting power;
b) detecting power transmission from the primary coil;
c) the secondary detector searching for a secondary coil inductively coupled to the primary coil;
d) if the secondary coil is not a detector, the primary coil is disconnected from the power source.

  Several power delivery technologies and configurations have been described and described above. These techniques use an inductive feed inductor (primary inductor) that is coupled to a secondary inductor connected to the appliance. Various embodiments can replace the conductive feed with associated sockets and trailing drag lines with an elegant solution.
