     DETAILED DESCRIPTION 
       [0013]      FIG. 1  illustrates a system  10  for providing therapy to a subject  106  and/or promoting health effects in subject  106 , according to one or more embodiments. The therapy and/or health effects may include, but are not limited to, one or more of pain relief, relief of discomfort, reduction of inflammation, improved range of motion, hair growth, tissue repair, regenerative effects, improved circulation, improved micro-circulation, and/or other types of therapy and/or health effects on living organisms. System  10  may include a body  85 , a first wire  86 , a current source  11 , and/or other components. The depiction of the size of subject  106  relative to the size of body  85  is not meant to be limiting. 
         [0014]    Body  85  of system  10  in  FIG. 1  includes two intertwined helically wound runners—runner  88  and runner  89 —sharing the same (circular) axis, coupled by struts  90  and having one or more conductive wires spirally wound around one or both runners. In other words, runner  88  and runner  89  of body  85  form cores around which wire  86  and wire  87  are spirally wound, respectively. As depicted in  FIG. 1 , body  85  includes two wires: wire  86  and wire  87 . In some embodiments, system  10  includes one runner, three runners, and/or another number of runners. 
         [0015]    Runner  88  and runner  89  of body  85  and system  10  in  FIG. 1  are arranged in the shape of a three-dimensional curve similar to or substantially the same as a helix, bend with its ends arranged together. It is noted that the shape of body  85  resembles the general shape of DNA. The shape of the cross-section of a runner may include one or more of a circle, an oval, a square, a triangle, a rectangle, an angular shape, a polygon, and/or other shapes. The width and height of the cross-section of a runner may be limited for practical purposes. For example, for the purposes described herein, in some embodiments, it may be preferable to arrange body  85  such that there is available space within the periphery of body  85 , as shown, e.g., in  FIG. 1 . As depicted in  FIG. 1 , the shape of the cross-section of runner  88  and runner  89  may be a circle. Note that embodiments of this disclosure are not intended to be limited by any of the given examples. 
         [0016]    Runner  88 , runner  89  and/or struts  90  of system  10  in  FIG. 1  may be manufactured from one or more of plastic, plastic plated with metals including copper, nickel, iron, soft iron, nickel alloys, and/or other metals and alloys, and/or other materials. In some embodiments, runner  88 , runner  89  and struts  90  are manufactured from non-conductive material. Runner  88 , runner  89 , and struts  90  may be manufactured from different materials. Runner  88 , runner  89 , and struts  90  may be manufactured through integral construction or formed separately prior to being assembled. The preceding statement is not intended to limit the (process of) manufacture of bodies similar to or substantially the same as body  85  in any way. 
         [0017]    Referring to  FIG. 1 , wire  86  and wire  87 , as any wire listed in any figure included in this description, may be insulated, uninsulated, or partially insulated and partially uninsulated. 
         [0018]    The shape of body  85  of system  10  in  FIG. 1  may be generally toroidal. In some embodiments, the body of system  10  may be arranged in any planar shape, including circular, polygonal, and/or other shapes. Alternatively, and/or simultaneously, a body such as body  85  may be arranged in a three-dimensional curve (a.k.a. space curve). Runner  88  and runner  89  of body  85  may form cores around which wire  86  and wire  87  are spirally wound, respectively. As such, wire  86  and wire  87  may be arranged in a helical shape having axes that coincide with runner  88  and runner  89 , respectively. As shown in  FIG. 1 , wire  86  and  87  may be wound such that they go around any of struts  90  of body  85  and/or around any points of engagement between one of struts  90  and one of runners  88  and  89 . The number of wire turns per complete revolution of a runner and/or the number of wire turns between adjacent struts may be characteristic measurements/features of body  85 . In  FIG. 1 , wire  86  and wire  87  are arranged to make approximately three to five turns between adjacent struts associated with runner  88  and runner  89 , respectively, and/or some other number of turns. The depiction of  FIG. 1  is intended to be exemplary, and in no way limiting. 
         [0019]    Wire  86  may include two leads—lead  86   a  and lead  86   b.  Wire  87  may include two leads—lead  87   a  and lead  87   b.  In system  10 , body  85  is electrically coupled with one or more power sources and/or current sources, such as, e.g., current source  11  and/or a current source  12 , arranged such that electrical coupling with one or both of wire  86  and wire  87  may be established, e.g. through coupling of current source  11  with lead  86   a  and  86   b  of wire  86  and through coupling of current source  12  with lead  87   a  and  87   b  of wire  87 . The current supplied to wire  86  may be a direct current or an alternating current. The current supplied to wire  87  may be a direct current or an alternating current. The currents supplied to wire  86  and wire  87  may flow in the same direction or the opposite direction. In some embodiments, the leads of wire  86  and wire  87  may be electrically coupled with the same current source. 
         [0020]    For alternating currents, operating frequencies ranging from 0 Hz to 100 GHz are contemplated. Operating currents ranging from 1 pA to 10 A are contemplated. Operating voltages ranging from 1 mV to 20 kV are contemplated. In some embodiments, a root mean square voltage of less than about 1.6 V is supplied to wire  86  and/or wire  87 . In some embodiments, a root mean square voltage of greater than about 0.25 V is supplied to wire  86  and/or wire  87 . In a preferred embodiment, the frequency of the alternating current supplied to wire  86  and/or wire  87  is between 0 Hz and 20 kHz. In some embodiments, the current is less than about 1 pA, 1 nA, 1 mA, 100 mA, 250 mA, 500 mA, and/or other amounts of current. The operating frequencies for wire  86  and wire  87  may be the same or different. Other electrical operating characteristics of current supplied to wire  86  and wire  87 , such as phase, may be the same or different. System  10  may be used to exploit the electromagnetic field that is created in and/or around body  85  when electrical power is supplied to one or more wires of body  85 . The electromagnetic field provides therapy to subject  106  and/or promotes health effects in a subject. 
         [0021]    For the purposes of this description, the electromagnetic field may be an electromagnetic field of at least a predetermined threshold level of tesla. The predetermined threshold may be 1 pT, 1 nT, 1 mT, 10 mT, 100 mT, and/or another threshold. 
         [0022]    Some embodiments of an electrical system including a body similar to or substantially the same as body  85  in  FIG. 1 , thus including wire  86  and wire  87 , may be configured to have a current in wire  86  flowing in the opposite direction as the current in wire  87 . In some embodiments the current supplied to one wire may be a direct current, whereas the current supplied to another wire may be an alternating current.

         [0025]    In some embodiments, body  85  may be configured such that the dimensions of the available space within the periphery of body  85  and/or the passage formed through the centroid of the shape of body  85  are predetermined dimensions. In some embodiments, a predetermined dimension may include a diameter of about 1 inch, about 1 foot, about 2 feet, about 4 feet, about 6 feet, and/or another suitable dimension. Suitable dimensions may depend on average sizes of human fingers, wrists, elbows, arms, ankles, knees, legs, shoulders, (lower) backs, torsos, bodies, and/or other body parts, as may be used as an area to receive treatment and/or therapy. 
         [0026]    In some embodiments, lead  86   a  and  86   b  of wire  86  and lead  87   a  and  87   b  of wire  87  are electrically coupled in the same circuit. This circuit may include, for example, one or more resistive components, such as resistors, that are arranged such that the circuit has a nominal impedance of a predetermined value, such as, e.g., 4 ohms, 8 ohms, 16 ohms, 32 ohms, 100 ohms, 600 ohms, and/or another predetermined value. In some embodiments, the predetermined value may be chosen to match the impedance of standard consumer electronics components and/or systems, including for example audio consumer electronics. These examples are not intended to be limiting in any way. By way of non-limiting example, additional information regarding resistive elements and/or impedance matching may be described in the &#39;347 application. 
         [0027]    By way of illustration,  FIG. 2  schematically illustrates a system  10   a  for providing therapy to a subject and/or promoting health effects in a subject.

Referring to  FIG. 4 , the one or more wires of body  85  are configured to receive current through the leads of the wires such that an electromagnetic field is created at or near the centroid of the toroidal shape of body  85 . The electromagnetic field provides therapy to subject  106  and/or promotes health effects in subject  106 . 
         [0039]    Support structure  44  may be configured to support one or more of subject  106 , supporting posts  42 , body  85 , and/or other components of system  10   b.  In some embodiments, support structure  44  may include a platform and/or base. 
         [0040]    Support structure  85   b  may be configured to support body  85 . Support structure  85   b  may be configured to mechanically couple to one or more of support posts  42 , raising mechanism  43 , and/or support structure  44 . In some embodiments, support structure  85   b  may include a shelf and/or tray. Support structure  85   b  may include an open area in the center that coincides with a passage formed through body  85  such that support structure  85   b  and body  85  may be moved relative to the position of subject  106  within and/or inside that passage. In other words, body  85  may be disposed around subject  106  and/or move up and down to cover different body parts of subject  106 . For example, the movement of support structure  85   b  and body  85  may be substantially vertical, as depicted in  FIG. 4 . Note that this example is not intended to be limiting. Embodiments in which subject  106  is placed in a substantially horizontal position are also contemplated. In such a case, the position of other components, which may include body  85 , support structure  85   b,  supporting posts  42 , and/or other components, may be adjusted accordingly. 
         [0041]    Supporting posts  42  may be configured to support one or more of body  85 , support structure  85   b,  raising mechanism  43 , and/or other components of system  10   b.  The depiction of two supporting posts  42  in  FIG. 4  is not intended to be limiting. 
         [0042]    Raising mechanism  43  may be configured to move body  85  and/or support structure  85   b  in a predetermined manner or path. For example, the predetermined path may be up and down, as depicted in  FIG. 4  and indicated by the arrows near raising mechanism  43 . The depiction of two raising mechanisms  43  in  FIG. 4  is not intended to be limiting. In some embodiments, raising mechanism  43  may include an electric motor and/or lift. 
         [0043]    Control of one or more raising mechanisms  43  during operation of system  10   b  may include one or more of a determination of a starting position relative to subject  106  and/or supporting structure  44 , a determination of a direction for the movement of body  85  and/or support structure  85   b  relative to the orientation and position of system  10   b,  a determination of the speed of the movement, a determination of the range of movement (e.g. in relation to a particular body part of subject  106 ), a determination of the number of sweeps across (all or part of) subject  106 , a determination of the intensity level, frequency, and/or particular sound information corresponding to the electromagnetic field used, which may vary depending on the position of body  85  or along different parts of subject  106 , and/or other operating conditions of system  10   b.  For example, to treat a specific back problem for a particular subject, raising mechanism  43  may be controlled to start at the center of the intended area of treatment, and may be subsequently controlled to sweep across a predetermined range of movement, e.g. a range of 10 inches on either side of the center, for a predetermined period or a predetermined number of sweeps, as intended for body  85  and/or support structure  85   b  to provide treatment as prescribed. In some embodiments, control of the operating conditions of system  10   b  may be implemented by a computer program module that is executed by a processor. For example, a set of sweeps as described above in relation to a specific back problem may be controlled programmatically by a computer program module. 
         [0044]      FIG. 3  illustrates a method  300  for providing therapy to a subject. The operations of method  300  presented below are intended to be illustrative. In certain embodiments, method  300  may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of method  300  are illustrated in  FIG. 3  and described below is not intended to be limiting. 
         [0045]    In certain embodiments, method  300  may be implemented in one or more processing devices (e.g., a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information). The one or more processing devices may include one or more devices executing some or all of the operations of method  300  in response to instructions stored electronically on an electronic storage medium. The one or more processing devices may include one or more devices configured through hardware, firmware, and/or software to be specifically designed for execution of one or more of the operations of method  300 . 
         [0046]    At an operation  302 , a body is arranged at or near one or both of a subject and/or a body part of the subject. The body includes two intertwined helically wound runners, and a conductive wire. The runners are arranged in at least two complete revolutions per runner. The body is arranged in a toroidal shape having a centroid. The wire is carried by the first runner. The wire is spirally wound around the first runner. The wire has two leads configured to be electrically coupled to a current source to receive a first current through the wire. In one embodiment, operation  302  is performed by a user of system  10  (shown in  FIG. 2  and described above). 
         [0047]    At an operation  304 , a current is supplied to the two leads of the wire such that an electromagnetic field is created at or near the centroid that provides therapy to the subject. In one embodiment, operation  304  is performed by a current source similar to or substantially the same as current source  11  (shown in  FIG. 1  and described above). 
         [0048]    Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
