Description

WEARABLE POWER SUPPLY

FIELD OF THE INVENTION

The present invention relates to magnetic electrically conductive mechanical connectors, and in particular to the mechanical and electrical connection of a battery electrical power source to a hand held, body mounted or other mounted electrical load. The present invention embodies a self-aligning articulated conductive magnetic attaching system providing a mechanically flexible electrical connection for a battery power supply, together with a battery or plurality of batteries comprising a battery pack with associated connectivity, and controls, and further magnetically facilitated power coupling to an electrical load.

SUMMARY OF THE INVENTION The present invention reveals a battery connection method facilitating rapid battery exchange. The mechanical connection and electrical contact is provided by the attraction of magnetic conductors. The present invention further reveals the electrical attachment and mechanical support of the battery and magnetic and electrical connection to the electrical load. It further provides for geometric reversibility or other alignment of the battery connection eliminating any possibility of reversed electrical polarity during attachment. It further reveals means for the connection and alignment of conductors with the aligning forces provided by magnetic action. Further, the present invention facilitates the relief of side loading forces as the magnetic connector has limited freedom of motion without losing electrical contact or mechanical retention.

An application of the present invention is the powering of a hand held power tool such as a drill, tattoo machine or sprayer by a battery and power control system mounted on the users hand, arm or body. This removes the battery weight from the tool, reducing fatigue and facilitating a smaller and more maneuverable tool use. It further removes the need for a tool power cable connected outside the local work environment, reducing load on the tool. The cabling connected to the tool by the present invention is closely and naturally aligned with the users body proving maximum range of motion and reducing the mechanical loading of the tool or the user.

The principal components of the present invention include a Battery Pack that further includes associated control and safety electronics equipped with Battery Pack Connector Magnets providing both structural and electrical contact with a load to include an arm Band or other body mounted connector device. In a typical application of the present invention the Band will receive electrical power from the Battery Pack and distribute under controlled means to an electrical load, such as a hand tool. The Battery Pack may be exchanged by simply pulling it away from the Band and replacing it with a charged Battery Pack. It is a preferred embodiment of the present invention that this action be facilitated by a single hand without tools and that the action be smooth and magnetically assisted. It is a further preferred embodiment that the Battery Pack exchange be facilitated by a rotational twisting of the Battery Pack about the center Battery Pack Connector Magnet. Unless otherwise defined, all terms (including trade, technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or

constructions may not be described in detail for brevity and/or clarity. The term Load is to be interpreted as an electrical power or current, the terms articulated and moving are used interchangeably, and the terms tattoo machine or tattoo gun refer interchangeably to any power tool. The term tool is used universally to include any powered application, regardless of the geometry or location of the electrical and mechanical connection, including the direct connection of the present invention. The term floating is herein used to describe or augment items with articulated or moving connections. The term artist is interchangeable with a worker of any definition, for example a carpenter or a factory worker. The term body is herein used to indicate the full body and any part including all extremities.

DISCUSSION OF THE PRIOR ART

The present invention provides for the rapid removal and replacement of a battery power pack by electrically conductive magnetic means minimizing the time of a break in supply of electrical power to the load. The process includes the removal of the electrically discharged battery pack followed by the insertion and retention of a charged battery pack, the retention being facilitated by magnetic means, said means further incorporating electrical conduction, and the mechanical provision of degrees of freedom of motion or the battery pack relieving mechanical connection stresses and assuring continuous and assured electrical connection during operation of an electrical load. It also provides for the retention of a control device and the connection to a load. In the case of a hand held or body mounted load such as a power tool the present invention may be mounted on a body part such as the arm, hand or leg. In this manner the battery moves with the body without undue stress on the magnetic mechanical connection maintaining uninterrupted electrical connection.

The present invention further provides mechanical flexibility of the magnetic electrical connectors assuring electrical contact by mitigating minor alignment and facilitating mechanical contact.

Mounting the battery on the electrical load adds weight and complexity to the load, such as a power tool. This weight must be supported and moved with the load during use. The present invention provides for the flexible magnetic connection of the battery in a multiplicity of configurations, including attachment to the arm, leg or body further facilitating electrical connection to the tool via a short electrical connector and the convenience of electrical controls being available at the battery at all times. In this manner the present invention provides for no battery weight on the load, such as an electric tool.

Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation- specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

The present invention relates to the mechanical connection of electrical power and a load through conductive elements by action of integrated magnetic elements and associated controls. In particular to the conduction of electrical current via conductors brought into mechanical contact by integrated magnetic elements to power a load.

FIG. 1 illustrates the principal components of the present invention and their respective physical relationships. It is comprised of the individual components including a Battery Pack 1, Battery Pack Connector Magnets 2, Band 3, Control Knob 14 and Display 15 (hereinafter shown interchangeably as Integrated Controller 4), Power Output Connectors 5, Cable Connectors 6, Band Magnetic Connectors 7, and Cables 8. The Battery Pack 1 is comprised of batteries, not shown, with integrated electronics, controls, condition indicators and power regulation. The Battery Pack 1 is shown with three Battery Pack Connector Magnets 2, Power Indicator 9, Low Voltage Indicator 10, and Battery On/Off Switch 11. The Battery Pack 1 is shown housed in a non-conductive enclosure. This enclosure may be a shaped enclosure such as a box or may be a conformal coating of sufficient strength to maintain Battery Pack 1 as a unit and protect the contained battery and electronic elements from damage. The conformal coating is preferred to be durable and surfaced (such as rubberized) to accommodate handling and wearability. The Battery Pack Connector Magnets 2 are preferred to be coated or housed in a conductive cladding material that is preferred to be mechanically sound and electrically conductive.

Preferred materials comprising conductive cladding material include all conductors without restriction such as gold, silver, copper, nickel, aluminum and any conductive metal. Carbon, conductive plastics and compositions containing conductive materials are also preferred.

Conductive rubberized and elastomeric materials and composition materials providing a conductive path are also preferred as an improvement in the mechanical durability of the conductive cladding material.

The Power Indicator 9 is preferred as an audio, vibratory or light-emitting indicator. It activates when the Battery Pack Connector Magnets 2 are energized by Battery On/Off Switch 11.

Optionally, in the case where Battery On/Off Switch 11 is not integrated, the Power Indicator 9 is either not integrated or is configured to activate when current is conducted through Battery Pack Connector Magnets 2. When the Power Indicator 9 is configured as an optical indicator, the Power Indicator 9 is preferred to be a Light Emitting Diode, hereinafter referred to as an LED, as these devices are robust, water tolerant, low cost and in wide use. When the Power Indicator 9 is configured as an audio indicator technologies such as piezoelectric audio emitters are a preferred embodiment. Any optical, vibratory or audio indication or indicator is a preferred embodiment of Power Indicator 9, the prevailing selection factor being the particular use of the present invention.

Low Voltage Indicator 10 is preferred as an audio, vibratory or light-emitting indicator. It signals when the Battery Pack 1 voltage approaches or reaches a pre determined low voltage level. Low Voltage Indicator 10 may be digitally activated to an electrically on state at a determined voltage level or may function in an analog manner signaling with a small signal at first then stronger as the pre determined voltage level is reached. When the Low Voltage Indicator 10 is configured as an optical indicator, the Low Voltage Indicator 10 is preferred to be an LED. When the Low Voltage Indicator 10 is configured as an audio indicator technologies such as piezoelectric audio emitters are a preferred embodiment. Any optical, vibratory or audio indication or indicator is a preferred embodiment, the prevailing selection factor being the particular use of the present invention. The Battery Pack 1 supplies electrical power through Battery Pack Connector Magnets 2 to Band Magnetic Connectors 7. The electrical power supplied is AC or DC at a voltage and a current as required, and in the case of AC at a frequency as controlled by the Battery Pack 1 integrated electronics and power regulation.

Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 are electrically conductive magnets. They are arranged in a line and their electrical and magnetic polarities are selected to provide a correct electrical connection even if the mechanical connections are reversed. This means that the Battery Pack 1 may be removed, turned one hundred and eighty degrees around (reversed) and reconnected without changing the electrical connection. It is a preferred embodiment of the present invention that the outermost magnets, located at the first and third position of the line of magnets, be of the same magnetic polarity on their exposed side away from the Battery Pack 1, and that the center magnet have an opposite magnetic polarity on the exposed side away from the Battery Pack 1. It is a preferred embodiment that the magnets of the Battery Pack 1 are arranged to be of the opposing magnetic polarity to facilitate the magnetic connector to Band Magnetic Connectors 7.

In this manner the electrical polarities will always orient properly regardless if the Battery Pack 1 is attached in either direction. The present invention integrates magnetic and conductive functions that are further integrated with the battery pack and its various connections in the desired application forming a single unit providing a connectable battery function mechanically supported by the magnetic action of the electrically connecting element. It is a preferred embodiment of the present invention that a conduction function such as a ferromagnetic material be substituted for an opposing conductive magnet reducing the required number of magnets by as much as half. In this manner the assemblies will connect in any direction and can be aligned such that only one, two or all three magnetic actions of each assembly contact the magnetic actions of the other assembly. This may or may not be desirable depending on the application. Many other combinations and connection orientations are possible and are included as preferred

embodiments of the present invention. Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 are preferred to be configurable in many geometries. For example, they could be configured as a donut shape with a central conductor represented as Conductive Cladding Materials 47 as in FIG. 12. This geometry allows the Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 to be attached at any relative angle to each other.

The Band 3 facilitates the wearing of the present invention on an object such as an arm or leg, and houses Integrated Controller 4 while providing for the electrical output Power Output Connectors 5, along with the magnetic mechanical and electrical connection of Battery Pack 1 by Band Magnetic Connectors 7.

The Band 3 is preferred to be comprised of a flexible material suitable to be worn on the arm or leg, both preferred embodiments. Flexible materials suitable for the present application are wide ranging. Examples of synthetic fabrics include such items as polyester, neoprene including foamed material, acrylic, nylon, rayon, PVC, polypropylene, acetate, spandex, orlon (an Acrylic fiber) and Kevlar (an Aramid fiber), and many others. Examples of natural fibers include all plant and animal fibers used to produce a yarn or cloth. In this manner it can be attached with a Strap 18. These and other similar materials are preferred if the Band 3 is sewn into or otherwise attached to clothing. Harder or stiffer materials are a preferred embodiment for mounting on a surface or containment as is suitable to the situation.

Band 3 is preferred to be configured for attachment to an arm or leg or other body part as desired, or to objects such as a hat, helmet, tool or vehicle as required for the particular use or application. It is a preferred embodiment that Band 3 provides a contained space for electronics. Band 3 is retained by Strap 18.

The Integrated Controller 4 provides both user interface and electronic power control. Integrated Controller 4 is preferred to be configured as a touch screen integrated with or attached to Band 3. Band 3 further contains associated electronics as accommodate the desired configuration and function of Integrated Controller 4. Integrated Controller 4 provides the user interface to control the electrical potential, current regulation and frequency of the electrical output presented at Power Output Connectors 5. Integrated Controller 4 is preferred to contain all the required electronics interfacing with Battery Pack 1 and Power Output Connectors 5. Integrated Controller 4 may also be configured as a display and manual control, such as a knob or knobs controlling electronic devices such as a potentiometer contained within Integrated Controller 4 or within Band 3. Integrated Controller 4 receives electrical power from Battery Pack 1, converts and controls that power for use in terms of voltage, current and frequency as configured, and provides that power to Power Output Connectors 5.

Power Output Connectors 5 are preferred to be comprised of three conductive magnets arranged in a side-by-side order such that the outermost magnets are presenting the same magnetic and electrical polarity that is the opposite magnetic and electrical polarity of the middle magnet. It provides the power output as controlled by the Integrated Controller 4 from electrical power provided by the Battery Pack 1. The polarities are chosen to facilitate magnetic and electrical contact with Cable Connector 6. One or more Power Output Connectors 5 provided on Band 3 is a preferred embodiment.

The electrical power supplied by Battery Pack 1 through Battery Pack Connector Magnets 2 through Band Magnetic Connectors 7 and controlled by Integrated Controller 4, is output to Cable Connector 6 through Power Output Connectors 5. In this manner the controlled power is furnished through Cable 8 to the electrical Load 17 not shown.

The Cable Connector 6 is preferred to be comprised of three conductive magnets arranged in a complementary order both magnetically and electrically to facilitate mechanical connection with Power Output Connectors 5 and provides the desired conduction of electricity through Cable 8 to the electrical Load 17 not shown.

FIG. 2 illustrates a Battery Pack 1, Band 3, Integrated Controller 4, Cable Connectors 6, Body Part 19 in this case a wrist with a hand in a glove, and a Load 17, in this case a tattoo machine, soldering machine, hand drill or other electrically powered device. This configuration is typical for use of the present invention to power a hand held Load 17. Foot Switch 51 turns power on and off to Load 17. The Integrated Controller 4 is further preferred to embody run time meters and electronic recording to include session and total run time, and means to select and set a predetermined run time with an end of time indication including shutting off the power to Load 17. The Foot Switch 51 is preferred to be electrically connected to Integrated Controller 4 by electrical cable or wireless Radio Frequency communication, either mono or duplex operation, and is preferred to select the operation of the Load 17 be maintained or momentary as controlled by the Foot Switch 51. In momentary mode the Load 17 is powered when the Foot Switch 51 is pressed and not powered when the Foot Switch 51 is released. Pressing of the Foot Switch 51 embodies pressure applied such as by a foot or other body part, or other mechanical means as desired. In maintained mode the Load 17 is powered when the Foot Switch 51 is pressed and remains powered until the Foot Switch 51 is pressed again.

In the case of a tattoo machine the process involved in utilizing the present invention is procedurally as follows. The tattoo area is prepped normally, a charged Battery Pack 1 is removed from charging and inserted into Band Magnetic Connectors 7 and Integrated Controller 4 connected to the power supply connector of the tattoo machine via Cable Connectors 6 where it is electrically connected. Magnetic polarities are provided to prevent the possibility of reversing the electrical connection of the battery. This step seamlessly integrates into all set up steps with no additional work or delay by the Artist. Barrier film is then placed over the system comprised of a wrist mounted tool power controller and monitor with inserted Battery Pack 1 in order to protect it from cross contamination. The tattoo is then started at the artist's leisure.

A voltage control system allows the battery pack to deliver a constant voltage as set by and adjusted by the artist via wrist mounted Integrated Controller 4. The artist will take breaks from time to time as needed in order to restock supplies or allow the client to relax. The artist can switch the Battery Pack 1 by twisting as per FIG: 11, and removing the spent Battery Pack 1, immediately replacing it with a charged Battery Pack 1. This action is facilitated by a one-hand twisting operation so as not to disrupt the normal order of activities during the tattoo session. As compared to using conventional equipment the process of switching from an old battery to a fresh one with the present invention is very fast. This method of exchanging batteries provides for near seamless operation of the artists machine and avoids extended breaks in tattooing that would otherwise be required. An LED indicator tells the artist that the battery is connected.

The artist will have a general sense of the Battery Pack 1 remaining energy content by visual monitoring of a voltage display in Integrated Controller 4 displaying both the voltage level of the battery and the voltage level set to supply the tattoo machine. In this manner the artist can judge the approximate battery life remaining in the battery pack. It is a preferred embodiment of the present invention that the display be selectable to automatically switch between the voltage level of the battery and the voltage level set to supply the tattoo machine, or be selectable to simultaneously display both the voltage level of the battery and the voltage level set to supply the tattoo machine.

An LED indicator light or an audio alarm or an integrated vibration or any combination as selected and integrated into wrist mounted tool power controller and Integrated Controller 4 alerts the artist of a need to "quick switch" the Battery Pack 1 when a pre-set voltage level is reached by the Battery Pack 1. This assurers the voltage fed to the tattoo machine is constant and will not be interrupted by an overly drained Battery Pack 1. Once the indicator is noted, the artist will remove the drained Battery Pack 1 from the wrist mounted Band 3 and switch it with a charged Battery Pack 1 from the charging system. The barrier film is easily removed and applied during this time in order to keep all equipment sanitary.

All magnets and magnetic devices and implements in this disclosure include compositions of all know magnetic materials, and preferably includes materials containing an alloy of neodymium, iron and boron to form the Nd2Fel4B tetragonal crystalline structure commonly referred to as neodymium. It is a preferred embodiment that the electrically conductive properties of neodymium provide significant electrical conductivity and facilitate miniaturization of the device. All magnets are preferred to be covered in a conductive and mechanically sound overcoat. This present innovation facilitates the seamless "quick switch" of battery packs, providing the user an un-tethered "wireless" system to utilize during the process of powering the load, and adds no significant additional time to the work at hand.

FIG. 9 illustrates a Battery Pack Connector Magnets 2 shown firmly connected by Fastener 34 to a structural Substrate 33. Structural Substrate 33 may be selected as electrically conductive, insulated, or facilitating electrically conductive means. The Battery Pack Connector Magnets 2 is shown formed with a Cavity 29 so as to accommodate Fastener 34 attaching Battery Pack Connector Magnets 2 to Substrate 33 without interfering with the mechanical and electrical contact of Battery Pack Connector Magnets 2 to floating conductive magnet Band Magnetic Connectors 7 by magnetic means. Fastener 34 is structural and may also be electrically conductive further facilitating the transfer of electrical energy.

Floating conductive Band Magnetic Connector 7 is shown being electrically connected via flexible electrical Conductor 38 to an electrically conductive and mechanically connective structural Substrate 32. The motion of Band Magnetic Connectors 7 is retained and constrained by Fastener 31 and the mechanical interaction of Fastener 31 and Formed Cavity 30. Fastener 31 allows the mechanical motion of Band Magnetic Connectors 7 as defined by the length and shape of Fastener 31 in relation to the Formed Cavity 30 in Band Magnetic Connectors 7.

Formed Cavity 30 simultaneously facilitates and limits the aforesaid mechanical motion and provides for the mechanical retention of Band Magnetic Connectors 7. Fastener 31 is structural and may also be electrically conductive further facilitating the transfer of electrical energy.

Structural Substrate 32 may be selected as electrically conductive, non-conductive or facilitating electrically conductive means. The floating conductive Band Magnetic Connectors 7 is allowed to move along and be retained by Fastener 31. Formed Cavity 30 in magnet Band Magnetic Connectors 7 simultaneously defines the limits of motion of magnet Band Magnetic Connectors 7 in both the lateral, as in back and forth, and angular, as in other than parallel to structural Substrate 32. Floating conductive magnet Band Magnetic Connectors 7 facilitates motion and angular contact in reference to Battery Pack Connector Magnets 2, facilitating the making and maintaining of both mechanical and electrical contact when structural Substrates 33 and 32 are parallel or at a relative angle to each other.

When Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 are allowed to mechanically contact each other through magnetic action a conductive channel is formed through Fastener 34, Battery Pack Connector Magnets 2, floating conductive magnet Band Magnetic Connectors 7, mechanically flexible electrical Conductor 38, electrically conductive Fastener 31, and conductive structural Substrate 32. Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 are arranged so as to magnetically attract each other to connect the positive to the negative electrical poles of the battery, and repel each other when like electrical poles are brought near each other assuring an electrically correct battery orientation for typical battery operation. Structural Substrates 32 and 33 may be selected to be structural only or both conductive and structural.

Hereinafter, the fixed conductive Magnets 36 are comprised of the selective grouping of subcomponents Battery Pack Connector Magnets 2, Conductive Fastener 34, Structural Substrate 33 and Cavity 29.

In all further embodiments herein disclosed, the use of fixed conductive magnets such as Magnets 36 and/or movable conductive Magnet 37 are interchangeable and mutually

substitutable to address the preferred configuration and application. FIG. 10 illustrates three fixed Battery Pack Connector Magnets 2 aligned to intersect with conductive magnets of Band Magnetic Connectors 7. Battery Pack Connector Magnets 2 are chosen with a magnetic orientation to facilitate the desired mechanical connection with conductive magnets of Band Magnetic Connectors 7. For example, Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 may be oriented such that all Battery Pack

Connector Magnets 2 present the north magnetic pole with respect to floating conductive magnet Band Magnetic Connectors 7. Conductive magnets Band Magnetic Connectors 7 are oriented to present the south magnetic pole with respect to Battery Pack Connector Magnets 2. When Battery Pack Connector Magnets 2 and Band Magnetic Connectors 7 are brought together they attract each other and contact forming an electrically conductive connection. In this manner the assemblies will connect in any direction and can be aligned such that only one, two or all three magnetic actions of each assembly contact the magnetic actions of the other assembly. This may or may not be desirable depending on the application. Many other combinations and connection orientations are possible and are included as preferred embodiments of the present invention.

Conductive Magnet Assemblies 53, 54 and 55 are comprised of the fixed conductive magnet used in Battery Pack Connector Magnets 2 and conductive Fastener 34. Conductive Magnet Assemblies noted as 56, 57 and 58 are comprised of floating conductive magnet assemblies as herein described in their various forms. The magnetic and electrical properties of each of the conductive magnet assemblies are selectable in any of the various possible combinations. For example, Conductive Magnet Assemblies 53, 55 and 57 are selected to present the magnetic north pole. Conductive Magnet Assemblies 54, 56 and 58 are selected to present the magnetic south pole. In this manner the overall assemblies are mechanically reversible facilitating magnetic and electrical connection in a reversible orientation and preventing connection in anything other than a desirable magnetic and electrical orientation due to magnetic repulsion. For another example, Conductive Magnet Assemblies 53, 54 and 58 are selected to present the magnetic north pole. Conductive Magnet Assemblies 56, 57, and 55 are selected to present the magnetic south pole. In this manner the electrical connection is only allowed in the magnetically prescribed manner. The end magnetic action may connect in a useless manner, not connecting any of the other contacts, a one to one connection without mechanical guidance as herein provided.

Fasteners 34 are structural and are in this case electrically conductive facilitating the transfer of electrical energy.

Band Magnetic Connectors 7 are shown being electrically connected via flexible electrical Conductors 38 to a mechanically connective structural Substrate 32 or an outside conductor as desired. The motion of Band Magnetic Connectors 7 are retained and constrained by Fasteners 31 and the mechanical interaction of Fasteners 31 and Formed Cavities 30. Fasteners 31 allows the mechanical motion of magnets Band Magnetic Connectors 7 as defined by the length and shape of Fasteners 31 in relation to the Formed Cavities 30 in magnets Band Magnetic

Connectors 7. Formed Cavities 30 simultaneously facilitate and limit the aforesaid mechanical motion and provides for the mechanical retention of magnets Band Magnetic Connectors 7. Fasteners 31 are structural and may also be electrically conductive further facilitating the transfer of electrical energy.

The floating conductive magnet Band Magnetic Connectors 7 is allowed to move along and be retained by Fastener 31. Formed Cavity 30 in magnet Band Magnetic Connectors 7

simultaneously defines the limits of motion of magnet Band Magnetic Connectors 7 in both the lateral, as in back and forth, and angular, as in other than parallel to structural Substrate 32. Floating conductive magnet Band Magnetic Connectors 7 facilitates motion and angular contact in reference to fixed Battery Pack Connector Magnets 2, facilitating the making and maintaining of both mechanical and electrical contact when Substrates 33 and 32 are parallel or at a relative angle to each other. Substrates 33 and 32 are selected to be conductive or non-conductive either uniformly or in selected areas only. Facilitating constrained movement of the electrical and mechanical connection provides mechanical stress relief on the overall connection.

FIG. 11 illustrates a method of battery power pack removal by turning the Battery Power Pack 44 in relation to the Battery Power Pack Receiver 45 causing the fixed and moveable conductive Magnets 42 and 43 to slide apart at the outer ends of the Battery Power Pack 44 and the Battery Power Pack Receiver 45 decreasing the strength of the magnetic attraction by two thirds in this case facilitating removal of Battery Power Pack 44 by physically pulling away from the Battery Power Pack Receiver 45. The force of removal is assisted by the action of conductive Magnet 43 passing over optional repelling removal magnets (not shown), four each to facilitate separation of the shown assemblies in any twisting direction, applying the repulsive magnetic force of conductive Magnets 43 as they pass over removal magnets overcoming the attractive force of the center conductive Magnets 43 and 42 pushing the assemblies apart facilitating ease of separation. This twist-to-release method provides for enhanced ease of removal even when vary powerful magnets are utilized and is a preferred embodiment of the present invention. Battery Power Pack 44 is illustrated as a transparent backplane or structural substrate to more clearly exhibit the relative orientation.

These may be reversed as per the application. In the case of an alternating current connection the connections are made in reference to safety and electrical ground considerations. In this manner the magnetic action of the magnetic material contained in floating conductive magnet Band Magnetic

Connectors 7 facilitates the bringing of electrically Conductive Cladding Materials 46 and 47 into desired electrical contact through magnetic mechanical means. Flexible Substrate 48 is selected to facilitate the minor motions of Conductive Cladding Materials 46 and 47 when connected to a source or sink.
