Description

INDUCTIVE ENERGY SUPPLIER SYSTEM GIVEN WITH A MOBILE OUTPUT FIELD OF THE INVENTION The present invention is directed to providing an inductive power supplying system. In particular, the invention deals with the supply of energy through mobile inductive outputs.

BACKGROUND The supply of electrical energy where and when necessary, is an important consideration when building buildings. The number and location of electrical outlets necessary for each room depends on the use that will be given to the room. However, the future function of the room is often unknown during its construction. As a result, it is often necessary to relocate power outlets long after a building has been completed, which can be costly.

Conventional energy outlets are typically located at strategic points around room walls. A ring conductor to which the power outputs are connected can be provided. Said ring connector typically runs around a conduit tube embedded in the wall, and the supply boxes in or on the wall are connected thereto. The location of the energy outputs is determined in this way by the location of the fixed power boxes. Once the wall is finished, it is difficult to relocate the energy outputs.

In order to add or relocate power outlets, additional wiring must be provided. The additional wiring can be embedded in the wall by cutting a groove in the surface of the same, which runs through the wiring along the groove and is fixed on the wiring, with plaster, compound to close together or similar. Additional power outlets are typically introduced into depressions bored into the surface of the wall or alternatively into prominent power boxes that are bolted or bolted thereto. Another method for relocating current outputs is to connect a cable duct to the outside of the wall and place wiring through the external duct, connecting the energy outputs to the external ductwork. This solution is commonly used in schools, universities, laboratories and other institutions, particularly when the walls are constructed of solid stone, concrete or brick. It will be appreciated that this solution is expensive, time consuming and unsightly.

U.S. Patent No. 3,585,565 in favor of Price discloses an electrical tape and plug connector designed to facilitate and simplify the installation of electrical wiring. The substantially flat or film conductors are inserted between insulating layers of protective material. The walled construction includes an insulated ground conductor of two mains power supply conductors. A surface or side of the tape or cable is coated with a pressure sensitive adhesive. A three-leg connector fits the tape or cable to a utility outlet.

Price's solution allows the wiring to run flat against a wall surface that allows wiring to be less obstructive and easier to install. However, the installation of utility outlets requires the removal of the insulation from the conductive tape and the connection of a special plug. In addition, the utility outlet once connected can not be removed without exposing the bare conductor.

An alternative system is described in U.S. Patent Application Number 2002/0084096 in favor of Chang. Chang discloses an electrical wire coupling device that includes one or more electrical wires having one or more electrical wires connected and that are received in an outer rubber cover. One or more contacts each have a contact box and two conductive elements secured in the contact housing, which align with the holes in the contact housing to receive the plugs. The electrical wires and / or contacts each have an adhesive material to adhere to the support wall without other fasteners. The contact may include a side opening to join the other electrical wires.

In Chang's system, the electrical strip and exits stick to the surface of the wall and protrude from it. In addition to being unpleasant to the eye, if protruding contacts are hit, they can detach from the wall. Because the contacts and the wires are supported only by the adhesive and not by additional fasteners, if the contacts are detached from the wall, these will only be supported by the wire itself, thereby representing a safety hazard.

Conventional electrical contacts have holes in them in which the terminals of the corresponding plugs are inserted to form a conductive coupling. For safety, the energy spout side of the coupling is usually the female part, and has no bare driving elements protruding therefrom. The plug coupled to the device is the corresponding male part, which typically has bare terminals. The size of the terminals and the buildings are such that even a small child can not insert their fingers in them. In high quality contacts, a ground connection is provided, and, only when a longer ground terminal plug is inserted into it, it is possible to insert a terminal (or anything else) into the holes connected to the wires active and neutral current carriers. However, children sometimes manage to insert pencils, pins and other objects into the holes in the socket, sometimes with deadly results. Water can also cause a short circuit and can result in electrocution.

Since the contacts are unsightly, the number of contacts installed on a wall is normally limited. Often, their position is not appropriate to change the requirements and extension tops are required.

For these and other reasons, there is a need for alternative power supply to the conventional contact outlets occasionally placed along a wall and the present invention takes care of this need.

DESCRIPTION OF PREFERRED EMBODIMENTS Reference is now made to Fig. 1 which shows a schematic diagram of an energy supplying system according to an exemplary embodiment of the present invention. A workspace 1, like a corner of a room, limited by walls 2a, 2b, a ceiling! 2c and a 2d floor, contains a variety of electrical appliances 4, like a! television set 4a and a lighting article 4b, for example. Said electrical appliances 4 are adapted to pull power from inductive power output 6. It is a particular feature of one aspect of the invention that the inductive power outputs are incorporated in the: boundary surfaces 2 of the room, such as walls, ceiling and floor of! the same.

I The inductive power coupling allows the energy to be transferred from a power source to an electric load without providing a path of conduction between them. A power supply is connected to a primary inductor and an electric oscillation potential is applied through the primary inductor that induces a magnetic field of oscillation. The magnetic field of oscillation can induce an oscillating electric current in a secondary inductor placed i near the primary inductor. In this way, the electrical energy can be transmitted from the primary inductor to the secondary inductor by electromagnetic induction j without the two inductors being connected conductively. When electrical power is transferred from a primary inductor to a secondary inductor, the pair is said to be inductively coupled. An electric charge connected in series with such a secondary inductor can draw power from the power source when the secondary inductor is inductively coupled to the primary inductor.

In the inductive power outputs 6, the primary inductors 7 are connected to a power source, such as the power grid, for example, through a combiner. The combiner provides the appliances; electronics needed to excite the primary coil. Said apparatuses; electronic devices may include, for example, a switching unit that | provides a high frequency oscillation voltage through the primary inductor I to excite the same.

The electrical devices 4 can receive energy from the inductive power outputs through the secondary inductors 5| configured to inductively couple with the primary inductors 7 j twenty i i of the inductive power outputs 6. As will be pointed out in more detail below, in some embodiments of the invention, the secondary inductors 5 can be housed in induction receiving units connected to the electrical devices 2. In other forms of embodiment the secondary inductors can be incorporated into the same electrical devices.

According to various embodiments of the invention, the inductive energy outputs can be incorporated into prefabricated building materials. With reference to Fig. 2, a plasterboard panel 100 according to an embodiment of the invention is shown. The drywall panel 100 consists of a layer of construction material 102, such as plaster or the like, placed between lining sheets 104, 106 which are typically made of paper. Incorporated in the gypsum board panel 100 are one or more primary inductors 108A-F and connecting wires 110, 1 12 which extend to the edge of the panel 100 allowing it to be coupled to a mains power supply ( it is not shown).

If they are bulky, the primary inductors 108A-F can be crimped into the building material 102. However, it will be appreciated that the primary inductors such as the induction coils 108A-F can be relatively thin and simply adhere to or adhere to each other. they adhere to the lining sheet 104 designed to be the outer lining surface of the panel 100.

The primary inductors 108A - F and the driving wires! i 1 10, 1 12 can be manufactured from wires or foil, such as! a sheet of aluminum or copper. Alternatively, the primary induction coils 108A-F and the conduction wires 1, 10, 112 can be printed or painted on the trim sheet 104 using conductive inks.

Flow guide cores can improve coupling: electromagnetic of the primary coils 108 with secondary coils 604 (Fig. 6) which are placed near them. In certain embodiments of the invention, the flow guide cores (not shown) for example of ferrite or amorphous ferromagnetic material are associated with each primary coil and are crimped into the walls. Other components such as ferromagnetic barrier elements or the like can be further incorporated therein. ! I With reference to Fig. 3, the gypsum board panel 100 can be incorporated into a wall 200, such that a standard drywall comprising plasterboard panels 202 installed as a dry wall; standard that is composed of 202 drywall panels installed in a 204 structure. i For use in bathrooms and the like, the drywall panel 100 can be usefully made of water-resistant 'green' gypsum board. In fact, it will be appreciated that the term "gypsum board" is used rather generally in the present and can refer to other building materials, in particular those used for walls, such as gypsum, gypsum board. , gyproc, sheetrock or similar.

Referring now to Fig. 4 which shows an unrolled roll of wallpaper 300. The wallpaper 300 is composed of a flexible sheet 302 of a sheet material which is typically a paper or cloth, the j front surface 301 may be printed or patterned. At the rear 304 of the flexible sheet 302, a plurality of coils of | primary induction 308. The primary coils 308 may be fabricated from a foil and adhered to the flexible foil 302, or may be composed of conductive inks printed on the flexible foil 302 by silk screens for example.

With reference to Fig. 5, the wallpaper 300 is designed to be glued on the surface of a wall 400. The primary coils 308 are designed to be glued to the surface of a wall. they are configured to inductively couple with the secondary induction coils 602 (Fig. 6). Said secondary induction coils 602 can be transported by power adapters 420 used to supply energy outputs adhered to the surface 402 of the wall 400; connecting the secondary induction coils to electrical appliances, such as light fixtures 460 or televisions 480, for example; or in furniture such as tables and the like (not shown), close to the wall, and having conventional power outlets or inductive power outputs in them./////////// The energy adapters 420 can be secured to the walls j 400 using adhesives or they can be screwed or fixed with bolts. ! ! Alternatively, the magnets can be crimped into the wall to be magnetically coupled with the corresponding magnets that are inside: of the power adapters 420. Preferably, the power adapters 420 can be easily exchanged between different power points without the need for additional wiring. It will be appreciated that the! i 420 power adapters are incorporated into the devices such as! j a 480 TV, music system or similar. It is also observed that! a single apparatus such as television 480 may comprise more than one primary induction coil 308, thereby allowing the apparatus to extract; energy of more than one energy point. This can be useful in several! applications, where the energy needed by an apparatus is greater than the energy 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 can be decorated much or have a very coarse texture to hide the electrical components thereunder, such as the primary induction coils 308 in the back of the same and the electric driving strips 310, 312 extending to the edge of the paper 300 for | be coupled to the power supply of the electric network.

Optionally, the paper 300 has an adhesive surface 306 on the back surface thereof, to adhere to a wall 400. The previously self-adhesive self-adhesive wallpaper is known, and the technologies thereof can be adapted for the users. 1 induction papers that are described in the present. Thus, optionally, a waxed release layer or a lining sheet 307, such as a low density polyethylene or the like, adhere to the self-adhesive layer 306. The lining sheet 307 can be peeled off, allowing the paper 300 adhere to a surface, such as a wall 400, through the exposed adhesive surface 306 thereof. Alternatively, the front surface 301 may be coated with a coating of waxed peel-off material, so that when the self-adhesive layer is Unroll 306 separates manually with ease. Other possibilities will present themselves to wallpaper setters.

Referring now to FIG. 6, in certain embodiments of the invention, control boxes 500 can be wired to a ring connector 540 to supply the electronic devices needed to drive the primary coils 508 crimped or adhered to each other. walls 510. Exciter electronic devices (not shown) j can be supplied. For example, these may include a switching unit that provides high frequency oscillation voltage supply and an output selector to select the power output that Í is going to be excited. The control box 500 can be connected to the primary coils j 508 by pressure connectors 520 such as flat PCB connectors for example. Optionally, the connection power ribbon 560 can be provided without primary induction coils but with strips of! í driving (do not appear) to connect between walls 510 and a box of > 500 control A power adapter 600 may include a secondary induction coil 602 connected wired to a conventional J power outlet 604 to which a conventional power plug (does not appear) I it can be attached. Alternatively, the secondary induction coil 604 can be wired directly to an electrical load as a light apparatus 460 or the like. When the secondary induction coil 604 in a power adapter 600 is aligned with a primary induction coil 508 in the wall 510, the energy can be transferred inductively between the coils thus providing energy to a load.

Referring now to FIG. 7, an exemplary configuration of electronic components is shown within an energy wall section 700 according to another embodiment of the invention. A common electrical driving strip 710 connects to all the coils of! primary induction 708 within a column. A control strip 712 consists of a bundle of conductive wires each of which: connects to only one of the primary induction coils 708. Wherever the power wall breaks, the common electrical conductive strip! 710 and control strip 712 can be connected to a control box 500 (Fig. J 5). The control strip 712 thus provides a means for selectively actuating each primary induction coil individually. The configuration of 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 understood by one skilled in the art.

Typically, before plastering a wall, the plaster tape is used to cover the joints in the drywall. The plaster tape, typically a ribbon of paper made of canvas or jute, helps maintain the integrity of the surface and reduces the risk of the plaster cracking along the joints. 1 The self-adhesive plastering tape is known from the description that Stough makes in the United States Patent No. j i 5,486,394. The Stough tape helps to quickly cover the seams between units of adjacent drywalls, and is supplied in rolls. The tape j has a first layer of flexible paper material with a coating Pressure sensitive adhesive with internal orientation in it. A second layer of reinforcing woven fiber material is superimposed on the first layer. A third layer of flexible material is superimposed on the woven fiber material to encapsulate the fiber material between the first and second layers. The third layer has a release liner with outward orientation so that the adhesive of the first layer joins with releasability to the third layer for manual separation of the tape when it is wound on itself. A fold is formed along the center of the tape to facilitate the placement of the tape in a corner of the wall. The self-detachment properties of the tape allow it to be easily distributed and applied without the need to remove a liner. The adhesive is formulated to maintain adhesion even when wetted by a superposed layer of drywall paste. further, the release layer in the third layer accepts and allows the adhesion of the drywall paste such as the joint compound, the plaster and the like.

Reference is now made to Fig. 8a which shows a roll of energy output ribbon 800 incorporating inductive energy outputs 842 according to another embodiment of the invention. The energy output ribbon 800 is constructed of 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 contains electrical elements including a series of power outlets 842 and electrical lead strips 844, 846. The third layer 860 overlies the second layer 840 thereby leaving the electrical components between the first layer 820 in between. and the third layer 860.

The electrical components of the second layer 840 are electric conducting strips 844, 846 and a series of primary induction coils 842. The primary induction coils 842 are configured to inductively couple with secondary induction coils carried by energy adapters that can be used. to provide energy outputs on the surface of a wall.

Preferably, the outer surface 862 of the third layer 860 is coated with a coating of release waxing material such as a low density polyethylene or the like, such that when rolled the adhesive surface 822 of the first layer is easily separated from the surface. the outer surface 862 of the third layer 860, typically by hand. Alternatively, a release liner paper (not shown) covered in a wax release material may adhere to the adhesive layer 822 to protect the adhesive surface and to prevent dust and the like from sticking to it as well as to prevent the tape 800 it sticks prematurely to objects.

Fig. 8b shows an alternative embodiment of an energy output ribbon 800 'comprising a two dimensional array 840' of primary induction coils 842 '. Three rows of primary induction coils are each provided with their own pair of conductive strips 844'a-c, 846'a-c. It is noted that said tape roll 800 'may be useful for covering large areas such as table tops, work surfaces or the like. Thus, the alternative energy output ribbon 800 'can be used to provide a series of remote power points.

With reference to Fig. 9a, the energy tape 800 is shown while being applied to a wall 900. Drywall 920 panels of material such as plaster, gypsum board, gyproc, sheetrock or the like are installed on a 940 frame In order to obscure the seams 960 between the adjacent drywall panels 920, the segments of the energy outlet tape 800 are used to bridge between the adjacent drywall panels 920. The drywall panels 920 and the taped seams 960 create a substantially flat surface on which the plaster 980 can be applied. It is noted that the plaster 980 containing ferromagnetic material can provide additional flow guidance for the inductive couplings. In the prior art, the bridging function can be performed by paper, jute ribbon or other scrim tape without crimped electrical components.

The ends of output power strip segments can be connected to the control box 600 by means of pressure connectors 520 such as flat PCB connectors for example. Optionally, the connecting power ribbon (not shown) can be provided without primary induction coils but including conducting strips for connection between the output power strip 800 and the remote control box 500. The control boxes 500, they are wired to a ring connector 540, provide the electronic devices needed to excite the primary induction coils 842, such as a switching unit that j provides high frequency oscillation voltage supply and an output selector to select the energy output that is going to be excited. j Inductive power adapters are used to power ! 29 Í I appliances installed on the wall as shown in Fig. 9b and 9c. With particular reference to Fig. 9b, a fully plastered wall 950 is shown, which hides two segments of energy output ribbon 810a, 810b each with five power points in each of which a primary induction coil is located 842a - j. Each segment 810a, 810b is connected to a control box 500a, 500b which is wired to a ring connector 540. Several example apparatus units include, among others: a single plug power adapter 420, a power adapter double plug 440, a light fixture power adapter 460 and a wall mounted television 480. The power adapters 420, 440, 460 can be secured to the walls using adhesives or by screwing them into place. Alternatively, magnets can be set in the wall to be magnetically coupled in the adapters 420, 440, 460. The power adapters 420, 440, 460 are easily exchanged between power points without the need for any other wiring.

It will be appreciated that power adapters can be set in apparatuses such as a 480 television, music system or the like. It is noted that a single apparatus such as television 480 that appears in Fig. 9b may encompass more than one primary induction coil 842g, 842h, thereby allowing the apparatus to draw energy from more than one power point if required , for example when the necessary energy is greater than the energy supplied by a single primary induction coil 842.

With reference to Fig. 9c, a representation of an inductive power adapter 600 coupled to an energy point 842 is shown along a segment of energy output ribbon 810 that is connected to a control box 500. In the power adapter 600, a secondary induction coil 602 is wired to a conventional power socket 604 which can be coupled to a conventional power socket. Alternatively, the secondary induction coil 604 can be wired directly to an electrical load such as a light apparatus or the like. When the secondary induction coil 604 in a power adapter 600 is aligned with a primary induction coil 842 in the energy output ribbon 800, the energy can be transferred between the coils thus providing energy to a load.

Two embodiments of the energy output ribbon are shown in Figs. 10a and 10b. With particular reference to Fig. 10a, of the first embodiment, the electrical components 840 are configured such that a common electrical conduit strip 844 is connected with all the primary induction coils 842 along the belt. Such control tape 846 may consist of a bundle of conductive wires each of which is connected to only one of the primary induction coils 842.

A segment of the energy outlet tape is detached from the roll, perhaps by cutting the tape with fingers or using a cutting implement such as a pair of scissors or a knife. Wherever the energy output ribbon is cut, the electrical conductor strip 844 and the control strip 846 can be connected to a control box 500. With this first configuration, the control strip 846 can be used to selectively activate each coil of primary induction 842. 31 i A second embodiment of the electrical components 640 of the energy output ribbon is shown in Fig. 10b. Here, each primary induction coil 642 is connected to its own dedicated pair of conductive strips 644, 646. The pairs of conductive strips of each primary inductive coil 642 extend along the energy output ribbon at a sufficient length that Cutting the tape along any line provides access to three pairs of conductive strips. In that way, by cutting the ribbon of the second embodiment along the line A for example cutting provides contacts to the pairs of conductive strips 644b-d, 646b-d which control each of the following three primary induction coils 642b, 642c, 642d. While cutting the ribbon of the second embodiment along the line C for example, it provides contacts to the pairs of conductive strips 644d-f, 646d-f that control each of the following three primary induction coils 642d , 642e, 642f. It will be appreciated that, although only three primary induction coils can be individually controlled in the energy output belt of the present, the number of individually controlled primary induction coils depends on the length of the extension of the conductive strips 644, 646. Of that Thus, a range of tapes with variable conductor extension lengths can be provided to provide different numbers of individually controllable primary induction coils.

Now U.S. Patent US 6,444,962 to Reichelt, is incorporated herein by reference, discloses a heating arrangement consisting of at least one heating element in the form of a flat element with two essentially parallel, opposite conductors and a coating placed between them for the generation of electromagnetic waves. The coating material is composed of an agent: binder, an insulating agent, a dispersing agent, water and graphite. The heating device is also composed of a control device: with a harmonic generator that contains an electrical component that has a fast speed of current increase and is suitable for generating high harmonic content. The harmonic generator is coupled to both electrical conductors of the heating element in order to emit a spectrum of Í vibrations in natural molecular frequency ranges. A highly effective heating system is provided in this manner, which, in one embodiment, is a flat panel that can be provided in a coiled form similar to the wallpaper. Thus, heating elements installed on the wall, planes that can be incorporated into the wallpaper are known.

With reference again to Fig. 1, it has surprisingly been found that it is useful to provide induction coils 6 or ferromagnetic screens having relatively high internal resistance, so that in addition to inducing an electric current, the oscillation of an electric current i in it, it also produces a heating effect. Said | The heating effect can be used as a convection heater to heat room 1, and usefully, induction coils having high resistance are placed under the floor 2d or under a window, thus facilitating the effective circulation of heat in the room. room.

In open design areas, such as offices, factories, workshops, i i exhibition halls, warehouses and the like, it is often necessary to provide power to electrical appliances at a distance from the walls. To avoid long cables, power can be supplied from contacts installed in floors or ceilings, however, these two approaches are problematic. The plugs and cables installed in floors of the prior art can be kicked or stepped which can damage the connections and even cause injuries to people who are in the place and in many situations it is convenient that the floor is free of electrical outlets and long cables. The aerial power supply requires that the cables be lowered from the ceiling which can be unpleasant to the eye and impractical when the ceiling is high, such as large hallways and auditoriums and for outdoor use, where there are no ceilings.

With reference to Fig. 11, a solution to the above problem is proposed, where the inductive power outputs installed on the 1200 floor are connected through wiring under the floor 1220 to a power source (not shown) either directly or through a control unit (not shown). The primary induction coil units 1200 are configured to inductively couple to secondary coils 1300 which are placed on top of them, which are themselves coupled to the electrical loads 1320, 1325. In this manner, the open floor contacts are avoided. It will be appreciated that the system 1100 as described herein may be used with a variety of floor types such as carpet, fixed mats, parquet, linoleum, tile, tile, and cobbled surfaces and the like.

The devices installed in the 1320 device, such as 1320a floor lamp or a 1320b photocopier, with secondary induction coils 1300 in the bases thereof can be placed directly through the primary coils installed on floor 1200.

Alternatively, the 1325 furniture as a 1325a desk or chair; 1325b with secondary coil 1300 therein can be placed on the primary coils installed on the 1200 floor and can serve as platforms for energizing the 1340 electrical appliances placed on | such as a 1340a desk lamp or 1340 desktops such as 1340b laptop computer or a 1340c novel coffee cup that directly heats the liquid in it.

Such devices 1340 may be wired to furniture j 1325, plugged into contacts (not shown) at the top of the table or may themselves include secondary coils 1500 and interconnected with primary coils 1400 on the surface of the part! top of table 1326.

Other electrical devices into which the secondary coils 1200 can be incorporated to align with the primary coils 1200 of; 1100 system include home appliances such as floor lamps, j televisions, music centers, video players, DVDs, and, if adequate voltage is available, including washing machines, clothes dryers and the like, | as well as cooking appliances such as ovens, cooking pots! slow, hot plates, refrigerators and freezers, for example. In the workplace, the 1 100 system can be supplied to power j devices installed on the floor such as paper shredders, fans, photocopiers, computers, printers or heavy machinery. j It is further noted that the furniture 1325 can be equipped with primary coils 1400 incorporated therein to be coupled with secondary coils 1500 associated with the work apparatuses. Furniture in which said primary coils are incorporated includes chairs, tables, work benches, partition walls, cupboards or the like.

Appliances that are placed on top of the table that have integrated secondary coils 1500 which can be aligned with the primary coils 1400 that are incorporated into a table surface 1326 for example include desk lamps, ambient lighting units, fans, cordless telephones , speakers, hands-free phone, base units for conference calls, electric pencil sharpeners, electric staplers, screen devices, electric photo frames, VDUs, projectors, televisions, videos, music centers, computers, calculators, scanners , printers, fax machines, photocopiers, paper shredders, hot plates, electrically heated cups and mobile phones.

There are a number of electrical appliances for personal hygiene that are used preferably in the privacy of the bathroom. These include shavers, toothbrushes, hair dryers, hair tubes and the like. Other electrical appliances are also found in the bathroom, which include heaters and lamps. Water and electricity should be kept separate however. Electrocution in bathrooms is a real risk, and light switches are usually located outside the bathroom, or are installed on the ceiling with pull cords. These problems can Solve with battery-powered devices, which have disposable or rechargeable batteries. However, disposable batteries are expensive and damage the environment. Neither disposable batteries nor rechargeable batteries are particularly reliable as they run out of energy at half use. 1 Very often, the bathroom walls are covered with ceramic tiles and the surrounding areas of the sink are typically made of polished natural or artificial stone, stainless steel, ceramics, or acrylics to provide easily cleanable surfaces that can be repeatedly washed. . For safety, electrical contacts in the bathroom are typically covered with water resistant covers. It will be appreciated that the output contacts of. energy, are more difficult to clean than work surfaces, since the contact holes for the plugs of the plug, and the switches must be kept dry to avoid short circuits or even worse electrocution.

By supplying power to the devices through an inductive coupling, the risk of electrocution inside the bath can be reduced. From; In fact, some devices can be used inside the bathroom.

With reference to Fig. 12a, a schematic representation of an electrical apparatus, such as a music player 2010, is shown. J Instead of having a wired plug to plug it into the power output contact i, a secondary coil 2012 is provided in the base 2014! same. The electrical apparatus 2010 can receive energy by placing it on a surface 2016 such as a sill edge, which incorporates a primary induction coil 2018, so that the secondary coil 2012 aligns with the primary coil 2018. ' The primary coil 2018 is connected to a power supply J | 2019 through a driver 2017 that supplies the necessary electronic devices to excite the primary coil 2018. The electronic excitation devices may include a switching unit that provides a high frequency oscillation voltage supply, for example.

It will be appreciated that apart from a music player 2010 this: energy solution may be appropriate for a wide variety of other devices and devices such as hair dryers, shavers; epilators, heaters, wax melting equipment, hair tubes, j trimmers, bathroom scales, televisions, radios, etc. The coil! Primary can be hidden behind a lining layer 2015 from the surface of the bathroom, such as a ceramic tile edge or wall tile. The J The primary coil can also be incorporated in the wall or in the door of a bathroom cabinet, behind a vinyl or formica surface layer, for example. Similarly, a primary coil may be hidden under or in the floor such as under or in a mat, carpet, parquet, linoleum, floor slabs, tiles, paving and the like, allowing a device to be placed on the floor and Operate without being plugged in through a visible power cord. In fact, the primary coil can be incorporated into a tarja or tub, ceramic or acrylic. j i Fig. 12b is a schematic representation of an apparatus; electric 2210 having a secondary coil 2212 connected thereto through a cable 221 1, with a series of suction cups 2213 for joining j the secondary coil 2212 to a surface 2026, on a primary coil | 2218 within it. The primary coil 2218 is connected to a source of; 2219 feed through an exciter 2217.

It will be appreciated that preferably the bath surfaces are smooth, which allows them to be easily cleaned. This feature allows the suckers 2213 to be used to temporarily attach lightweight objects to the bath surfaces 2216. Optionally, one or more suckers 2213 are placed in proximity with the secondary coil 2212, to connect the secondary coil 2212 on the primary coil 2218.

With reference to Fig. 12c, occasional splashes of the showerhead are inadvertently directed to the light points 2310. When < said points of light receive electricity from the electrical network, there is the possibility of electrocution so the light points of the bathroom must be totally enclosed. It will be appreciated that the light points 2310 according to the embodiments of the present invention can be completely isolated from the power source 2302 through a dielectric material 2304, and be equipped with a secondary coil 2312. The primary coil 2318 can be incorporated inside table green water resistant rock 2320, for example. This is how an alternative safe approach to bathroom lighting is provided.

With reference to Fig. 12d, a drawer 2400 in a bathroom cabinet: 2405 is shown. The drawer 2400 contains one or more primary coils 2418. In fact, the base 2404 thereof can be covered with a large rectangular primary coil 2418 coupled to the mains power source (not shown). A plurality of rechargeable devices such as electric toothbrushes 2424, hair dryers 2426 and razors 2425 can be recharged by providing the devices with secondary coils (not shown) and then placing them inside the 2400 drawer.

With reference to Fig. 12e, additionally or alternatively, a dedicated platform 2500 is provided, with dedicated primary coils 2518 therein for recharging specific apparatus. For example, a toothbrush j 2500 with primary coil 2518 therein may be provided to recharge one or more electric toothbrushes 2524 that can be stored therein through a secondary coil j 2512 therein.

With reference to Fig. 12f, a digital bathroom scale 2600 with secondary coil 2612 under it can be placed on a primary coil 2618 set on the 2620 floor, or placed under a bath mat, i (not shown).

Thus, some embodiments of the present invention eliminate the conventional energy outlet contacts in the bath, which are difficult to clean and have an inherent risk of electrocution.

Certain appliances, such as refrigerators, freezers, stoves; and dishwashing machines are consumers of energy, large appliances that tend to be plugged into dedicated contacts, and that rarely move, apart from allowing the cleaning of the space beneath them and behind them. Such devices have good service by technology | conventional conductive energy.

Many other household appliances in the kitchen and gadgets, such as egg beaters, bread makers, juicers, orange juice extractors, vegetable juice extractors, processors 40 ! food, electric knives, toasters, household sterilizers, sandwich toasters, popcorn makers, magnetic stirrers, waffle makers, electric grills, slow cookers, hot plates, deep fat fryers, electric frying pans, grinders Knives, electric can openers and the like are occasionally used and are preferably stored in cupboards when not in use to keep work surfaces available for manual labor.

Ideally, such devices should be able to be used anywhere; available work surface, including the runoff part of the I I table, useful work surfaces for tables, table top and the like. The well-designed kitchen of the prior art has double energy output contacts installed in the walls above such working surfaces, allowing said occasionally used devices to be plugged in and used when desired. ( Kitchens, which are used to prepare food for human consumption, must be kept hygienically clean. The I walls often have ceramic tiles and top of the tile furniture that is typically made of polished stone! stainless steel or formica, to provide a surface of easy cleaning that can be washed repeatedly. It will be appreciated that the energy output contacts are cleaned less easily than the work surfaces, and that the contact holes for the plugs of the plug, and the circuit breakers, can not be removed.

I can stay dry and avoid short circuits or worse, electrocution. \ Teapots particularly are problematic, as they should Fill regularly from the tap (tap). For safe use, the teapot must be disconnected from the mains and in suitably designed kitchens, the contacts are not located near the dishes, and the teapot cables are short. In order to avoid carrying the cord with the plug, which is dangerous, the teapot cords are normally disconnected at the connection point to the teapot. However, if this connection point gets wet, there is a real danger that it short-circuits and burns or triggers a fuse, which is inconvenient, and also avoids a real danger of electrocution, which is even more serious.

For some applications, these problems can be solved by battery-powered devices, which have disposable or rechargeable batteries. However, disposable batteries are expensive and ecologically harmful. Neither the disposable nor the rechargeable batteries are particularly reliable as they seem to run out of energy in the middle of tasks, and for devices that require a lot of energy such as teapots and fryers, battery power is not a practical option .

With reference to Fig. 13a, a schematic representation of an electrical appliance 3120, specifically a toaster, is shown. Instead of having a plug in an electric cable for plugging it into the power output contact as with conventional apparatuses, a secondary coil 3124 is provided in the base 3122 thereof. The electrical apparatus 3120 can receive energy by placing it on a work surface 3140 incorporating a primary induction coil 3144, so that the secondary coil 3124 is aligned with the primary coil 3144.

It will be appreciated that although a toaster is described herein as an example, the electrical appliance 3120 can be any of a wide variety of appliances or devices such as egg blenders, machines! for making bread, blenders, orange juice extractors, vegetable juice extractors, food processors, electric knives, sandwich toasters, waffle makers, electric grills, pots | slow cooking, hot plates, electric fryers, electric pans, knife sharpeners and household sterilizers, teapots, kettles, radios, cassette players, CD players, and electric can openers, i The primary coil 3144 is connected to a power supply | 3160 through a driver 3180 that provides the electronic devices necessary to drive the primary coil 3144. The electronic exciter devices may include a switching unit that provides a high frequency oscillation voltage supply, for example.

The primary coil 3144 may be concealed behind a trim layer 3142 of the kitchen work surface, or the table. The layer ! can be a sheet of plastic with viscous reverse, vinyl, formica or veneer, for example. Similarly, a coil! primary can be hidden under or inside the floor as under or inside! i a carpet, fixed carpet, parquet, linoleum, floor tiles, paving, paving and the like, allowing the domestic appliance to be placed on the floor and operated.

| In a preferred embodiment, the primary coils; can be placed in a resin that hardens like artificial marble, what? is a polymer matrix composite that includes mineral filler, such as solid surface building materials, for example Corian ® or 1 the so-called Caesar ® Stone, manufactured in Israel. The Caesar ® stone that can be melted with tarras and the integrated squeegees. Unlike the 'real stone' that needs to be drilled from the back to provide a primary induction coil near the upper surface of the same,! When desired, Caesar ® stone and similar composite materials, including concrete, can be fused around inclusions such as metal objects, including induction coils and connecting wires. j Fig. 13b is a schematic representation of an exemplary electrical apparatus i 3120, again represented by a toaster, i having a secondary coil 3124 connected thereto through a flexible cord 3126, with a series of suction cups 3128 for fastening the coil I secondary 3124 to a work surface 3140, on a primary coil 3144 within it. j As with the embodiment of Fig. 13a, the primary coil 3144 may be incorporated within a horizontal surface 3140, such as a kitchen work surface. Otherwise, the primary coil can! hide behind or inside a vertical surface such as a wall of a building or a cabinet, for example inside the ceramic tiles of the wall, behind the wallpaper, behind a door or cupboard wall! I Formica, or similar.

Preferably, the surfaces of the kitchen with smooth, allowing ' I to be easily cleaned This feature allows the suction cups to be | Use to temporarily attach lightweight objects to kitchen surfaces. Optionally, one or more suction cups 3129 are supplied to hold the secondary coil on the primary coil.

The apparatuses of Fig. 13a and 13b further include a contact 3128 for connecting to an electric cable for supply of conductive energy, by plugging it into a conventional electrical power line power outlet.

Alternatively, as shown in Fig. 13c, a retractable cable 3123 that can be wound within the base 3122 of the apparatus 3120c is provided. In addition, as shown in Fig. 13c, although equally applicable to apparatus 3120a and 3120b of Figs. 13a and 13b, an energy storage means 3125 can be supplied, for storing energy, allowing the device to be charged and used when inductive or conductive energy is not available. This makes the apparatuses according to the invention truly portable and can be used on any work surface.

Now, lead-acid batteries, such as those used for automobiles, are designed to produce a large current burst, while rechargeable batteries are essentially designed to power electronic devices such as mobile phones and laptop computers for extended periods of time. periods of time. Embodiments of the present invention are directed to apparatuses that include capacitors or electrochemical energy supply devices designed to give appropriate power to electric motors for a number of seconds to two or three minutes, and thus are suitable for feed food processors, roasters, teapots and the like.

With reference to Fig. 13d, a storage area 3000, such as a drawer or cupboard having primary loading coils 3121 at the base thereof is shown. The devices with rechargeable component 3125 (Fig. 13c) can be stored in the storage area 3000, for its removal and use. In this way, rechargeable component 3125 is fully recharged when necessary.

In the energy dispensing systems described above, the energy outputs are generally fixed at predetermined locations. According to other embodiments of the present invention, the energy outputs can be moved to adapt to the requirements of the change. With reference to Fig. 14a, a mobile power outlet 4110, according to another embodiment of the present invention is shown to provide power to an electrical device, specifically a computer 4182. A primary coil 4120 adjacent to the rear face 4142 of a surface layer 4140, adheres to a positioning mechanism 4160. The primary coil 4120 is configured to inductively couple to a secondary coil 4180 connected to the computer 4182. The positioning mechanism 4160 is configured to move the primary coil 4120 behind of the surface layer 4140 so that the primary coil 4120 can be repositioned.

The primary coil 4120 is connected to a power source typically through a combiner (not shown) that provides the electronic devices needed to excite the primary coil 4120. The electronic excitation devices may include a power unit. switching, providing a supply of high frequency oscillation voltage, for example.

In some embodiments of the invention, the energy outlet 4100 can be incorporated in a vertical surface such as in a wall of a building or a cabinet. The primary coil 4120 can be moved behind a surface layer 4140 of the elastic wallpaper or canvas for example. Alternatively, the energy outlet 4100 can be incorporated behind a lining layer of a horizontal platform such as a desk top, a kitchen work surface, a conference table or a workbench for example of mica, formica or sheet metal of wood. In other embodiments, the primary coils 4120 are configured to move behind the floors such as carpets, fixed mats, parquet, linoleum, paving, paving, paving and the like.

Referring now to Fig. 14b, according to a first embodiment of the positioning mechanism 4160, the primary coil 4120 is placed between the surface layer 4140 and the base layer 4162. The primary coil 4120 is fixed to a carriage 4161, installed with j bearing 4163 and configured to roll on base layer 4162. A magnetic element 4166 such as iron, steel or preferably a permanent magnet j, adheres to carriage 4161. Magnetic element 4166 | it is configured to be pulled by a nearby magnetic attraction element j 4168 located on the front face 4144 of the surface layer 4140. To move the magnetic attraction element 4168 across the plane of the surface i 4140 drags the magnetic element 4166, dragging itself the primary coil 4120 under the surface case 4140 and placing it as shown in FIG. 47 I i require It will be appreciated that instead of the bearing 4163, the carriage 4161 is installed on other elements such as wheels, skis, magnetic levitation elements or the like. When applied, the movement of the positioning mechanism 4160 can also be assisted by contiguous facing surfaces with low friction materials such as Teflon ® (PTFE).

In a second embodiment of positioning mechanism 5160, as shown in Fig. 15a, a primary coil unit 5120 is slidably mounted to a rail 5162. The rail 5162 can run horizontally behind the valance 5141 of a wall 5140 for example. The primary coil unit 5120 is configured to be movable in various positions along the rail 5162. The primary coil unit 5120 can be manually pulled with magnets as in the embodiment of Fig. 15a. Alternatively, the primary coil unit 5120 can be installed on motorized wheels 5164 and configured to drive itself along the rail 5162.

It will be appreciated that the rail 5162 may be straight or curved and that 1 may even advance back and forth to cover a large area of the wall 5140, as shown in Fig. 15b. According to still other embodiments, more than one primary coil unit 5120b 'can be placed independently. Alternatively, a plurality of primary coil units can be moved all together.

Referring now to Fig. 15c showing a third form < of embodiment of the positioning mechanism 5160c in which a primary coil unit 5120 is installed with sliding capability with a floating rail 5162, which can be supported with displacement capability by a pair of generally perpendicular support tracks 5164 to form an adjustable H-structure 5165. Thus, the position of the primary coil unit 5120 can move behind a surface layer 5140.

It will be appreciated that in the embodiments where the positioning mechanism 5160 is oriented vertically, behind a vertical surface layer 5140 as we say a wall, the support tracks 5164 can be replaced by support pulleys. Such pulleys can be used to support the floating rail 5162 that can be lowered and raised by adjusting the pulleys either manually or with a drive motor. Alternatively, the primary coil unit 5120 can be suspended from a pulley installed on a rolling table configured to roll horizontally along a beam of fixed support structure extending the width of the wall.

According to a fourth embodiment of the positioning mechanism 5160d, as shown in Fig. 15d, a primary coil unit 5120 is attached to four guide wires 5162a-d. The lengths of the guide wires 5162a-d are independently controlled by pulleys, placed at four points defining the corners of a quadrilateral 5166. The position of the primary j-coil unit 5120 can be manipulated with the pulleys 5164 at any position within the quadrilateral 5166. It will be apparent that other configurations of three or more pulleys can be used to manipulate the primary coil unit i 5120 over two dimensions and that two or even a pulley is used to manipulate a primary coil unit along a line.

Referring now to Fig. 16a, in another embodiment of the invention, the primary coil unit 5120 is adjacent to the back face 6142 of the surface layer 6140 and is configured to be inductively coupled with a secondary coil 6180 placed in the front face 6142 of the surface layer 6140. The secondary coil 6180 may be connected to an electrical device such as a light source 6184 for example.

In order to maximize the inductive coupling between the primary coil 6120 and the secondary coil unit 6180, the space between them must be minimal. Therefore, the primary coil 6120 is preferably pressed as far as possible against the back face 6142 of the surface layer 6140. A clutch, such as a compressed helical spring 6122 for example, which drives the primary coil 6120 towards the back face 6142. Optionally, recesses can be cut in the back plate 6142, providing spaces 6146 therein, wherein the thickness of the surface layer 6140 is reduced. The primary coil 6120 can be coupled in one of these spaces 6146 for efficient inductive coupling by minimizing the thickness of the dielectric layer between the primary coil 6120 and the secondary coil 6180. A flow orientation core 6124, for example, comprising ferromagnetic material such as ferrite, can be incorporated into the primary coil 6120, the secondary coil 6180 or even within the surface layer 6140 to optimize the inductive coupling.

I However, pressing the primary coil 6120 against the rear face 6142 increases the friction between them and can prevent the movement of the primary coil 6120. Therefore, a release mechanism 6130 can be provided to disengage the primary coil 6120 from the face 6142. According to one embodiment of the release mechanism 6130, the primary coil 6120 is fixed to the distal end of a lever 6132 which is configured to rotate about a point P connected to a cart 6126. A first magnetic element of attraction such as a permanent magnet 6134 is attached to the proximal end of the lever > 6132 and is located near the rear face 6142 of the surface layer 6140.

As shown in Fig. 16b, the release mechanism 6130 is configured such that a second magnetic element 6133, which can be on one side of the front face 6144 of the surface layer 6140, can approach the first magnetic element 6134. The first magnetic element 6134 is attracted to the rear surface 6142 by the second magnetic element 6136. The lever 6132 rotates about the point P,, compressing the spring 6122 and disengaging the primary coil 6120 from the back face 6142 of the surface layer 6140. The cart 6126 is then free to transport the primary coil 6120 to a new position as required. It is noted that the first magnetic element 6134 and the second magnetic element 6136 can also provide a positioning mechanism 6160 as described in the embodiment of Fig. 14b.

It will be apprecd that, for automated systems, a preferred embodiment of the release mechanism 6130 may include ? electromagnets installed in the carriage 6126 behind the surface rate 6140. The electromagnets can be used to disengage the primary coil i 6120 from the back face 6142 thereby serving the function of the magnetic elements 6134, 6136 described above.

By not requiring holes for coupling pins, the inductive power outputs described above can effectively hide and clog less than the conventional power outputs. Generally, the fact that non-contact outputs are less obstructive is useful. However, it is more difficult to locate than conventional energy output what I have disadvantages and new problems to solve. Notably, the user must somehow locate the hidden output before it can be used.

The problem of locating such contacts is particularly serious when the energy outputs are behind a dissimulating surface I such as a desk top or wall, and installed in | positioning mechanisms as described above. When the ! The position of an energy outlet can be adjusted when installed on a track or arm, inside a wall cavity or hollow work surface and I When the surface is opaque, it is not possible to indicate the position of said energy outputs by making indicator marks on the surface j I dissembler ' With reference to Fig. 17a, a localizable energy output i 7100 is shown according to another embodiment of the invention. The locatable energy output 7100 includes a display screen 71 10 that can be incorporated into a surface 7140 such as a wall or j I work surface, to indicate the location of a primary coil 7120 hidden behind surface 7140. j The primary coil 7120 is connected to a power source, typically through a combiner (not shown) that provides the electronics needed to excite the primary coil 7120. The electronic exciters may include a switching unit that provides a supply of high frequency oscillation voltage, by (example. i According to certain embodiments of the invention, the! 7120 power coil can be hidden through a vertical surface such as a wall or a building or a cabinet. The primary coil 7120 can be hidden behind a surface 7140 of wallpaper or elastic canvas for example. Alternatively, the primary coil 7120 can be hidden behind a lining layer of a horizontal platform such as a part! top desk, a kitchen work surface, a conference table or a bench for example mica, formica or veneer. In other embodiments, a primary coil 7120 is concealed below the floor like carpets, fixed mats, parquet, linoleum, floor tiles, paving, paving and the like.

It will be apparent that when the place of the primary coil 7120 is known, a secondary coil 7180 can be aligned with it, as shown in Fig. 17b. When so aligned, the primary coil 7120 can inductively couple with the secondary coil 7180, thereby feeding an electrical device, such as a computer 7182, connected I to the secondary coil 7180.

In one embodiment, the location of the hidden primary coil 7120 is indicated to the user with a display 7110 incorporated in the surface 7140. The display 7110 displays a map 71 2 of the surface 7140 in which the display is indicated. place 7114 of the primary coil 7120.

Referring now to FIG. 17c, schematically showing an energy outlet 7101 according to another embodiment of the invention, it comprises an adjustable primary coil 7120, installed in an adjustable H-frame 7161 and concealed behind a wall. The adjustable primary coil 7121 can be controlled remotely from a control panel 7111 and the location of the adjustable primary coil 7120 is indicated by the position of a marker 7125 on a map 7123 shown on a control panel 7111.

It will be appreciated that a control panel 7111 may be a touch screen where the marker 7125 is a cursor that moves on a virtual map to control a positioning mechanism. Therefore, the marker 7125 indicates and adjusts the location of the primary coil 7121. Alternatively, the control panel 7111 can be a mobile mechanism switch, whose position indicates the location of the hidden primary coil 7121. Although the H-frame 7161 is represented here it will be apparent that other positioning mechanisms can be applied.

Referring now to Fig. 18a, a schematic representation of an energy outlet 8100 according to yet another embodiment of the invention is shown. The power output 8100 includes a hidden primary coil 8120 incorporating a transmitter, such as a light emitting diode 8110. A locating beam L is transmitted by the light emitting diode 8110 to indicate the position of the primary coil 8120. The surface 8140 is translucent for the wavelength emitted by the LED and thus the locator beam L can be detected by a photodiode that responds to the wavelength. It has been found that infrared radiation emitted by an LED behind a 0.8mm formica sheet can be detected by normal digital cameras including digital cameras of the type incorporated in many modern 8200 cell phones, for example.

It is observed that thin layers 8140 of many materials such as plastic, cardboard, formica or sheet of paper, are transparent to infrared light. Although a light emitting diode 8110 that transmits light in the infrared region of the electromagnetic spectrum is visible to the human eye, it is easily detectable by digital cameras and, if such an infrared light emitting diode is incorporated in a primary coil 8120, a mobile telephone standard 8200 equipped with a digital camera can serve as a detector to locate the primary coil 8120. It will be appreciated, however, that a powerful visible light emitter can be used allowing detection by pure sight, as long as the selected coating material is transparent / translucent for the specific wavelength in the emission intensity of the emitter and the thickness of the coating layer 8140.

It will be appreciated that the appropriate detectors can be selected and specified to detect specific electromagnetic wavelengths, including ultraviolet radiation, microwaves, radio waves or even shorter x-rays or wavelengths and thereby as long as the electromagnetic signal emitter and set the detector are considered together, there are a large number of essentially equivalent solutions for this problem. In addition, transmitters configured to transmit other types of radiation, including mechanical vibrations such as audible or inaudible (eg ultrasonic) sound waves, can be used to locate the hidden primary coil with the corresponding appropriate detection means.

It will be appreciated that the appropriate detectors can be selected and specified to detect specific electromagnetic wavelengths, including ultraviolet radiation, microwaves, radio waves or even shorter x-rays or wavelengths and thereby as long as the emitter and electromagnetic signal detector If they are set together, there will be a greater number of essentially equivalent solutions to this problem. In addition, transmitters configured to transmit other types of radiation, including mechanical vibrations such as both audible and inaudible (e.g. ultrasonic) waves, can be used to locate the hidden primary coil with the corresponding appropriate detection means.

Reference is now made to Fig. 18b which shows a block diagram representing an energy output 8101 according to another embodiment of the invention. A primary coil 8121 is configured to transmit a localized beam L carrying a coded location signal S identifying the location of the primary coil 8121. A mobile primary coil 8121 is connected to a power source 8112 through a switching unit 8114 and a microcontroller 81 16. The switching unit 81 14 is configured to intermittently connect the power supply 8112 to the primary coil 8121 with a bit rate frequency f. An 818 location monitor monitors the location of the primary coil 8121 and sends a location signal to the microcontroller 8116. The microcontroller 8116 is configured to modulate the bit index signal with the location signal S. The voltage applied to the primary coil 8121 can be a variable voltage modulated with frequency f, which carries a coded location signal s. It will be appreciated that the variable voltage can produce a radio wave of frequency f that can be transmitted as a locator beam L. Alternatively, the locator beam L can be transmitted by a dedicated transmitter, separate from the primary coil 8121.

A receiver unit 8201 including receiver 8221 can be provided. Receiver 8221 can be tuned to receive locator beam L of frequency f. The signal received from the locator beam L can be intercorrelated with a reference signal of the frequency f to isolate the location signal S. The location of the primary coil 8121 can therefore be transmitted to a remote receiving unit 8201, which can then send the location of the primary coil unit to a primary coil screen.

Although a digital indexed bit indexer L beam is described in the fourth embodiment mentioned above, it will be appreciated that the locator beam L can alternatively be modulated in other ways as by analog or digital frequency modulation or by amplitude modulation, for example.

The location monitor 8118 can monitor the location of the primary mobile coil 8121 while maintaining traces of movement of the I mobile primary coil 8121 in relation to some reference points. 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, can be used to monitor the movement of coil j primary mobile 8121 indirect, by triangulation for example.

A high-power inductive output, when active, produces a large oscillating magnetic field. When a secondary inductor is inductively coupled to the primary inductor, the link I The resulting flow causes the energy to be drawn to the secondary inductor. | When there is no secondary inductor to concentrate the energy, the magnetic oscillation field j causes high-energy electromagnetic waves to be transmitted which is harmful to the passers-by. In addition, considering that in low energy systems, excessive heat can easily dissipate, a disconnected high power primary coil or its surroundings can become dangerously hot. j Reference is now made to Fig. 19 which shows a block diagram of a 9000 energy leakage prevention system for a | inductive 9200 power output that can be turned on and off, i I The primary coil 9220 produces in the same alternating magnetic field only when a secondary coil 9260 is placed to extract energy therefrom.

The inductive power output 9200 consists of a primary coil i 9220, connected to a power source 9240 for inductively j coupling with a secondary coil 9260 connected to a load 9264. It is a particular feature of this embodiment of the present invention that a circuit breaker 9280 is connected in series between the power source and the primary coil 9220 and is set j so that, when activated, it disconnects the 9220 primary coil of the 9240 power supply. j The primary coil 9220 is typically connected to a source of < Power 9240 through a 9230 exciter that provides the necessary electronics to excite the 9220 primary coil.

I Excitation electronics may include a switching unit that provides a high frequency oscillation voltage supply, for example. When the power output 9200 consists of more than one primary coil 9220, the driver 9230 may further consist of a selector to select which primary coil 9220 is to be energized.

It is noted that the circuit breaker 9280 can be connected j between the driver 9230 and the primary coil 9220, in which case the circuit breaker 9280 disconnects only the primary coil 9220. Alternatively, the circuit breaker can be connected between the source! of power 9240 and exciter 9230, in which case the automatic switch I 9280 disconnects the exciter 9230 by itself, together with any primary coil 9220 connected thereto. j Circuit breaker 9280 is typically controlled by a combiner 9400 configured to receive a primary signal P indicating i that the primary coil 9220 is transmitting power and a secondary signal S indicating that a secondary coil 9260 is inductively coupled to the primary coil 9220 and pull energy from it. He combiner 9400 can typically be operated to operate the circuit breaker 9280 by thereby disconnecting the primary coil 9220 from the power source 9240 when a primary signal P is received but the secondary signal S is not received.

Figs. 20a and 20b are schematic diagrams representing an inductive power output 9201 protected by a local leakage prevention system 9001, according to another embodiment of the present invention. With particular reference to Fig. 20a, a primary coil 9221 may be concealed behind a lining layer of a horizontal platform 9641 such as a desk surface, a kitchen work surface, a conference table or a work bench. Said platform can be manufactured from a wide variety of materials, including mica, formica or veneer, for example.

In other embodiments, a primary coil 9220 can be concealed or crimped into flooring materials and covers such as carpets, fixed mats, parquet, linoleum, paving, paving, paving and the like. Alternatively, the primary coil 9221 may be crimped into or concealed behind a vertical surface such as a wall of a building or a cabinet, for example behind the wallpaper or elastic tarpaulin or the like.

The primary coil 9221 can be used to power an electrical device such as a computer 9262 connected to a secondary coil 9261; the computer 9262 is placed on the platform 9641 so that the secondary coil 9261 coupled to the computer 9262 is aligned with the primary coil 9221 hidden within the platform 9641.

In the preferred embodiments of the invention, a Primary detector 9421 is located in the place of primary coil 9221 and is configured to detect a magnetic field generated by a primary coil 9221 that actively transmits energy. The detector 9421 may operate in accordance with one or more of a variety of principles, including among others, magnetic detector elements, Hall probes, etc. Alternatively, the detector may be a heat sensor or electromagnetic sensor configured to detect one or more scientific effects inherent to or associated with the operation of the primary coil 9221.

A secondary detector 9441 is also provided, for detecting the presence or operation of the secondary coil 9261. The secondary detector 9441 can do this by detecting a signal from the secondary coil 9261 or detecting a signal from a primary coil or from its surroundings indicating directly or indirectly, the presence or absence of a secondary coil inductively coupled to it.

The secondary detector may be a heat detector 9441 configured to detect a significant temperature rise in platform 9641 in the vicinity of primary coil 9221. Alternatively, the secondary detector may be a magnetic sensor, a Hall probe, an electromagnetic sensor or similar, configured to detect transmissions from the secondary coil 9261.

With reference to Fig. 20a, a specific configuration is shown, so that when a secondary coil 9261 is inductively coupled to the primary coil 9221, energy transmitted by the primary coil 9221 is received by the secondary coil 9261, thereby feeding to the electrical apparatus 9262. Accordingly, the primary detector 9421 can detect a magnetic field generated by the primary coil 9221, and send a primary signal P to a combiner 9401 indicating that the energy is being transmitted through the primary coil 9221. to which the energy is being transferred to the electrical device 9262, where the secondary detector 9441 is a temperature probe, it does not detect an increase! significant temperature and can be configured to send a signal; secondary S to a 9401 combiner indicating that an electrical load is' I inductively coupled to the primary coil 9221, or not to send a signal, thereby providing an equivalent indication, depending on the logic programming of the combiner 9401.

In this way, if the combiner 9401 receives a primary signal P, i indicating that the energy is present in the primary coil 9221, and a secondary signal S, indicating that an electrical load is present, this does not activate the circuit breaker 9281 and primary coil 9221 continues to draw power from power source 9241.

When no secondary coil 9261 is inductively coupled to the primary coil 9221, as shown in Fig. 20b, the energy transmitted by the primary coil 9221 is dissipated through the! 9641 platform as heat. The primary detector 9421 again detects a I magnetic field generated by the primary coil 9221 and sends a primary signal j to a combiner 9401 indicating that energy i is being transmitted through the primary coil 9221. However, in this case, the secondary detector 9441 does detect a significant increase of temperature due to heat dissipated through platform 9641 and thereby sends a secondary signal S indicating that no electrical charge is inductively coupling to the primary coil 9221. The combiner 9401 receives the primary signal P, indicating that the energy is being generated, and the secondary signal S indicating that no electric charge is present, consequently the combiner 9401 activates the automatic switch 9281 by disconnecting by the same the primary coil 9221 of the power supply 9241 and avoiding any additional transmission of energy through the primary coil 9221.

Referring now to Fig. 21, a schematic diagram showing a plurality of inductive power outputs 9203 protected by a remote leakage prevention system 9003 according to another embodiment of the present invention is presented. A series of primary inductive coils 9223 are incorporated into a wall 9643 and connected to a power source (not shown) through an exciter 9233. The primary coils 9223 are placed to inductively couple with secondary coils 9263 connected to apparatus electrical, as a light source 9262, that approach them.

When a primary coil 9223 is activated, the exciter 9233 supplies a variable voltage that oscillates at a characteristic frequency f. Consequently, the primary coil 9223 transmits radio waves at a frequency of f. The remote leakage prevention system 9003 includes a primary detector such as radio receiver 9423 within the range of wall 9643, tuned to detect radio waves at the characteristic frequency f. Said radio probes indicate that at least one primary coil 9223 is transmitting.

The power output 9203 can also include a detector secondary 9443 for detecting a secondary coil 9263 inductively coupled to a primary coil 9223. The energy transmission can then be modulated with a secondary label indicating that a secondary coil 9263 is inductively coupled to the primary coil 9223.

The primary detector 9423 can then demodulate the radio probes to identify the secondary label. If the secondary card is not detected, the primary detector 9423 will communicate a control signal C to a combiner 9500 indicating that the energy is being transmitted by at least one primary coil 9223 in the absence of a secondary coil 9260. According to a In a basic embodiment, the combiner 9500 is operable to then operate a circuit breaker (not shown) thus disconnecting all the primary coils 9223.

Alternatively, the exciter 9223 may further be composed of a modulator (not shown) to label the power transmissions of each active primary coil 9223a - h with a primary tag only identifying the active primary coil 9223a - h from which the radio probes are being transmitted. The primary detector 9423 will then detect the primary tag thereby identifying which individual primary coil is transmitting the power in the absence of a secondary coil. The primary detector 9423 then communicates to the combiner 9500 which disconnects only the primary coil alone.

A method for preventing an inductive power output according to the embodiments of the invention from transmitting energy in the absence of an electrical charge coupled thereto, is presented in FIG.

Flow chart of Fig. 22. The method includes the following steps: (a) a primary coil transmits energy; (b) the energy transmission of the primary coil is detected; (c) a secondary detector searches for a secondary coil inductively coupled to the primary coil; Y (d) the primary coil is disconnected from the power source if no secondary coil is detected.
