     FIELD OF THE INVENTION 
     This application relates to electromagnetic radiation management systems, in the medical arts and in communications. 
     BACKGROUND 
     The field of radiation therapy (also known as “radiotherapy”), along with the sub-field of radiation oncology, seeks the control or treatment of biological processes through the use of electromagnetic radiation. Radiation therapy has been in use in some form for over a century, shortly following the discovery of X-Rays by Wilhelm Röntgen, in November of 1895. Generally speaking, radiation therapy accomplishes its goals by targeting living tissues with ionizing radiation, altering the tissue&#39;s size, structure, composition and function. For example, in cancer therapy, a beam of ionizing radiation may be focused spatially on a malignant tumor, destroying, among other things, the malfunctioning DNA which has caused it to de-differentiate from healthy to malignant tissue, and, thereby, arresting the disease process. Radiation therapy is especially useful in treating “inoperable” tumors, where the size and location create unacceptable dangers or where the prognosis for recurrence despite surgery is especially great, and surgical solutions are either deemed to be ineffective options, or to present too great a risk of injury or earlier death when weighed against the potential successful removal of the tumor. 
     Within the sub-field of radiation oncology, linear accelerator machines (“LINACs”) that generate megavoltage X-rays for deep-tissue penetration are currently in heavy use. LINACs are a form of “external beam” radiation therapy, in the sense that they generate radiation from outside of the treatment area and patient&#39;s body, and focus it inward toward the tumor. Other forms of radiation therapy include brachytherapy and systemic radioisotopes (where the radiation source is inserted, or taken by pill or injection, respectively). Like surgical intervention, brachytherapy causes collateral damage to healthy tissue from the trauma of the procedure. Systemic radioisotopes are even more rarely used, due to difficulties in targeting tumors or other targets, and system-wide collateral damage. 
     Although LINACs have the advantage of avoiding some of the tissue damage and other risks of invasive surgery and brachytherapy, and can cause less damage than systemic radioisotopes, they also present their own drawbacks. In most instances, the external beam of radiation must first pass through healthy, surrounding tissues before reaching the tumor. As a result, those tissues are also damaged, by the same process that damages the tumor tissue. And because a radiation beam can ionize the DNA of any biological cell in its path, LINACs cause mutations in healthy surrounding tissue, which mutations can lead, among other things, to cancer. Thus, ironically, radiation therapy bears a probability of causing new cancer, in addition to otherwise damaging surrounding tissues, even if it succeeds at destroying a current tumor. In addition to causing more cancer, a variety of other radiation therapy side effects are seen in collaterally-damaged, otherwise healthy adjacent tissues, including edema, neural and cognitive decline, hair loss, irritation and heart disease. 
     In tomotherapy and multiple-source fixed LINAC machines, the radiation source may be applied at a variety of isocentric angles from outside of the treatment area—all of which target the tumor—in order to disperse less of the radiation across a greater volume of healthy tissue, such that it can withstand the impact of the radiation more easily. Beginning in the 1990s, image-guided and intensity-, spatial approach- and beam shape-modulated radiation therapy techniques have been developed, which further seek to target tumors with greater accuracy. These techniques (hereafter, called “IMRT”) use advanced imaging technology and computer-aided dosage plans in conjunction with LINACs and other ionizing radiation sources, to target the diseased tissues and avoid collateral damage to more important healthy tissue with greater accuracy. For example, the RapidArc® machine, from Varian Medical Systems, Inc., employs computer modeling of 360-degree dosage plans (1) modulating the shape of the beam source through its escape aperture (via multiple collimating “leaves” that are extended or withdraw over the aperture) (2) controlling gantry (beam-emitting source) rotation speed, as well as (3) beam intensity, to deliver a more favorable dosage pattern. 
     Radiation therapy is often carried out over several sessions in a process called “fractionation,” rather than all at once, to give healthy, non-malignant cells more of an opportunity to heal following exposure. However, the diseased tumor cells may have more of a potential to survive treatment as well, through such timing techniques. In addition, the added time needed for radiation therapy treatments is disruptive to the patients&#39; life, as well as expensive and labor-intensive for both the patient and medical staff. 
     IMRTs employ a variety of particle and electromagnetic wave radiation beams. Most forms of radiotherapy have a decaying ionization profile, meaning that the particle or electromagnetic radiation beam&#39;s ionization energy tends to decrease as the beam penetrates deeper into tissue. An exception may be some forms of proton or heavier ion therapy, which exhibit what is known as a “Bragg Curve,” a phenomenon where ionization beam energy peaks shortly before the particles come to rest (assuming they do not fully exit the target or collateral tissue into space). Proton therapy has been rapidly developing in the hope that these heavier ionization decay profiles will allow for greater localization of radiation dosage to tumors, while decreasing dosage to healthy tissues. However, collateral damage is a major issue in these therapies due to significant dosage to healthy collateral tissues. 
     It is an objective of the present invention to increase the dosage effectiveness of external radiation therapy to target tissues, while decreasing the damage to collateral tissues. 
     The field of cryptography, codes have been used for millennia to protect private information and communications from exposure to third parties. Typically, codes involve applying a cipher given to trusted parties, such that they, and only they, can decode the encrypted information. A wide variety of approaches, including handshakes to bilaterally build ciphers unique to a given communication, have been developed—for example, in secure socket layer (SSL), used to maintain communications privacy widely in the Internet. 
     SUMMARY OF THE INVENTION 
     The present invention includes new techniques for radiotherapy. In one aspect of the invention, multiple sources of radiation are provided in preferably the same or a harmonic or otherwise planned frequency and in the same superposed period and polarization with respect to one another, from the same side of a target, focused on a leading structure in the target and are thereby made to interfere with one another at or near and before a target location, greatly increasing a vector sum of electromagnetic radiation wave amplitudes and ionization energy levels to the target tissue, or creating resonant, harmonic, higher energy or other critical frequencies concentrated in target-associated matter and structures. 
     In additional aspects of the present invention, two or more of such radiation sources create Encrypted Source Beams that, upon converging, create a Decrypted Result Beam, that can be received in the target area. In further aspects of the present invention, two or more converging waves are used to isolate one or more media components, within a multi-layered array of information storage media components, for a read or write event. 
     In other aspects of the invention, collateral structures and areas are protected by intentional electromagnetic interference from the opposing side of the target, causing a substantial proportion of standing waves in the electromagnetic field of the healthy tissue. This protective opposing electromagnetic interference may also be used to redirect leaked or Emerging-Slit radiation emerging from between a source and collimators and a target or related structure. In other aspects of the present invention, which may be combined with the previous aspects, by using tumor-size and healthy tissue-size related pulses, some damage directly from the ionizing beam is prevented in healthy tissue. In yet other aspects, the polarization of beams entering a target, and/or healthy collateral material, are altered relative to one another while the beams are sufficiently separated or isolatable by location of creation and direction of propagation to allow for a magnetic field to alter their relative polarizations at areas or points of superposition, to bring them into the same polarization and lead to building interference in a target, and thereby protecting collateral tissue prior to entry of the target. A reverse process with another magnetic field targeting the emergent radiation again deactivates their interference upon exiting the target. In other aspects of the invention, such a manipulable magnetic field system permits guiding particle therapy around key collateral tissues and into targets. 
     Aspects of the present invention are mediated by image-guiding and computational and executing hardware, which may implement real-time feedback, and independent modulation of sources, in response to such feedback in order to maximize the impact of radiation on a target, and maximize the protective effect on collateral structures. 
     Unless otherwise indicated, the following terms have the specific meaning described herein: 
     “Emergent-Slit Radiation”: “Emergent-Slit Radiation,” in addition to its ordinary meaning, means any energy waves that tend to emerge on one side of an opening or space between neighboring objects, due to energy transfer on the other side of the opening or space.
 
“Treatment Side”: The “Treatment Side” of a system refers to system components that are designed, configured or intended for use in Treatment, and not used for Protection alone.
 
“Protection Side” (or “Protective Side”): The “Protective Side” of a system refers to system components that are designed, configured or intended for use in Protection, and not used for Treatment alone.
 
“Fringe Radiation” (or “Leaked Radiation”): “Fringe Radiation” or “Leaked Radiation,” in addition to its ordinary meaning, refers to the unintended or undesired deviation of electromagnetic radiation or other wave-based energy transferring phenomena from a designated direction or path set forth for Treatment and includes, but is not limited to, such deviation resulting from the tendency of electromagnetic radiation to spread. Generally speaking, because radiation may be in the form of a beam of particles (which are known to contain wave as well as particle characteristics when in relative motion to an observer) as well or instead of typical electromagnetic radiation (such as gamma rays), when a statement in this application refers to radiation generally, it also should be read as a separate alternative statement referring to moving particle beam radiation, as well as the separate original textual statement, which still should be read in its ordinary sense, without the alternative statement, and each statement should be read separately from one another in the context of other surrounding statements.
 
“Encrypted Source Beam”: “Encrypted Source Beam,” in addition to its ordinary meaning, refers to an information-carrying wave (preferably, resulting from the modulation of a carrier wave) that contains only part of the information of a Decrypted Result Beam and that, when combined with another Encrypted Source Beam, superposes to form a Decrypted Result Beam at a receiving region, location or area.
 
“Decrypted Result Beam”: “Decrypted Result Beam,” in addition to its ordinary meaning, refers to an information-carrying wave that results from the superposition of two or more Encrypted Source Beams at a receiving region, location or area.
 
“Treatment” or “Treat”: In addition to its ordinary meaning, “Treatment” means any intended affect of using any wave-based phenomenon, controlled or manipulated by a system or user, on matter or the space, point(s) or region(s) the matter occupies and/or surrounding the matter, or co-locatable with it (any of which may be called a treatment “target”), including, but not limited to, the phenomenon of ionization of living tissues by ionizing electromagnetic radiation, or heating matter with radiation, or creating superposed waves of electromagnetic radiation in such matter, space, points or regions.
 
“Protection” or “Protect”: In addition to its ordinary meaning, “Protection” means any intended affect of using any wave-based phenomenon, controlled or manipulated by a system or user, on matter or the space, point(s) or region(s) the matter occupies and/or surrounding the matter, or co-locatable with it, to attenuate or otherwise reduce an effect of Treatment, including, but not limited to, creating a standing wave by superposing waves from opposing directions, resulting in no net energy transfer between two wave sources.
 
“Constructively-related Polarity”: In addition to the phrase&#39;s ordinary meaning, “Constructively-related Polarity” refers to two or more waves with a polarity such that, when the two or more waves converge, superpose optimally by maintaining or increasing the nature of their polarity. For example, two plane-polarized with the same plane polarization have a constructively-related polarity. Two waves with the same chiral polarity also have a constructively-related polarity.
 
“Beam”: In addition to its ordinary meaning, “Beam” means a wave, particle or group of waves or particles, originating from a common source, and which wave, particle or group of waves or particles, may, or may not travel parallel to or otherwise with a given fixed geometric relationship to other waves, particles or groups of waves or particles over time. For example, waves or particles within a beam may converge or diverge from one another, rather than simply run parallel to one another, depending on the focal and dispersion characteristics of the source.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  illustrates a preferred embodiment of aspects of the present invention related to the delivery of enhanced electromagnetic radiation to a target, such as a tumor embedded in the healthy tissue of a medical patient. The location of the exemplary target, in  FIG. 1 , is shown by a cross-sectional side view through a central plane, as a spherical structure, target  101 . In the upper-left corner, by the same view, an originating source  103 , of electromagnetic radiation, is pictured. This source may take a variety of shapes, forms and configurations which may be suitable for creating, defining and releasing a source of electromagnetic or particle radiation, such as those used in LINAC machines. A sine wave emanating from the lower right side of originating source  103  depicts an initial radiation emission  105 . Initial radiation emission  105  may be of any form of radiation with wave characteristics, but, preferably is tissue-penetrating and ionizing radiation, such as X-rays or gamma rays, in a Treatment-appropriate intensity and duration. Preferably, emission  105  is of a fixed frequency and polarity (and, even more preferably, of a chiral, circular polarization), which may be caused either by the actuating mechanism (e.g., frequency determining bombardment of a foil with particles) of the emitting appliance and/or a polarizing medium and/or filter (not pictured). Preferably, the frequency, polarity and intensity of the emission may be manipulated by the user and/or system with additional hardware and, optionally, software (not pictured). Radiation emission  105  propagates toward the lower-right corner of the figure at a 45-degree angle and next enters a beam splitter  107 . After entering beam splitter  107 , substantially one-half of radiation emission  105  is reflected (reflected emission  109 ) at a 45-degree angle, to the lower-left corner of the figure, while the other substantially one-half of the radiation (pass-through emission  111 ) carries directly through the beam splitter, in the original direction of propagation of beam  105 . Pass-through emission  111  next passes through an optional modulator  113 , which, preferably with a user interface and/or computational system (not pictured), permits the alteration of the intensity, phase, frequency and/or polarization of pass-through emission  111 . At the same time, reflected emission  109  next enters modulator/blocker  115 . As with modulator  113 , modulator/blocker  115  permits the alteration of the intensity, phase, frequency or polarization of its emergent radiation stream  117 . However, it should also be noted that the phase of reflected emission  109  may be varied by a choice of beam splitter as well. For example, if a higher refractive index material on the right-hand side of beam splitter  107  is used, reflected emission  109  will automatically have a phase 180 degrees opposing the initial radiation emission  105 . Such phase reversal is desired in aspects of the present invention, for reasons which will be explained, below. 
     Emergent radiation beams  117  and  119  next enter beam splitters  121  and  123 , respectively, yielding emergent beams  125 ,  127 ,  129  and  131 . It should be noted that, in another embodiment, beams  125  through  131  could themselves enter additional modulators, actuated by a control system. However, preferably, they are not modulated at this point in the stream of events. Potentially-created emergent beam  133  preferably is not created by the system but is depicted to illustrate the 180-degree reverse phase that might emerge if a different coupling of refractive materials is used in beam splitter  121 , with different relative refractive indices. Next, emergent beams  125  through  131  reflect against mirrors  135  through  141 , creating emergent beams  143  through  149 . 
     At this point, it is useful to refer to emergent beams  143  and  145  as being within a class of system components termed the “Treatment Side” of the system. The Treatment Side serves to deliver ionizing or otherwise target-affecting radiation to a target. Meanwhile, emergent beams  147  and  149  may be described as being within the “Protective Side” of the system. The Protective Side serves to moderate or reduce the net force or affect of radiation emerging from the Treatment Side in areas where such moderation or “Protection” is desired. The Treatment Side and Protective Side components are described further in  FIG. 2 . In the instance depicted in  FIG. 1 , it may be assumed to be desired to affect target  101  with ionizing radiation. Thus, beams  143  and  145  converge upon the target and, preferably and as will be explained further, below, with a greater amount of their radiation beams focused on and converging on the leading portions (facing the beams) than on the distal portions of the target. However, beams  147  and  149  (the latter of which is only partially pictured, for 2-D illustration purposes) pass through a series of mirrors, including pictured mirrors  150  through  153 , resulting in an emergent beam  159  hitting a diffusing media and complementary target clone  161  and  163 . The size, angles, orientation and refractive indices of the diffusing media and complementary target  161  and  163  are selected to match or approximate those of the actual target  101  and collateral material  165 , such that any emerging radiation  167  is matched by emerging radiation from an opposing angle  169 , which is, owing to the distances and angles of components chosen by the system and/or user, matched in phase with emerging radiation  167 . As a result, a portion of emerging radiation  167  is superposed through interference with emerging radiation  169 , creating standing waves, which do not transfer ionizing energy. 
     Turning again to radiation waves in beams  143  and  145 , converging on the leading volume of target  101 , the system has caused the radiation wave in beam  143  to be in-phase, identically polarized and to have the same frequency and, preferably, the same energy and amplitude. Therefore, as the beams converge, they superpose and interfere—substantially increasing in power, Kerma and Joules per kilogram of Treated matter in the areas of convergence and superposition. In general, assuming that the two converging radiation beams are of identical energy, they will vector sum as they converge, according to the formula 2R cos Ø, in which R is a measure of the energy level or strength of each of the adding source beams, shown as vectors  171  and  173 , and Ø is the angle between each of the source beams and the resulting beam vector  175 , which angle Ø is shown as  177  in  FIG. 1 . Where, as in the example angles shown in  FIG. 1 , the angle Ø is 45 degrees, the resulting vector sum  175  and beam  179  is therefore approximately 71% of the strength of the scalar sum of the two beams, as a result of the vector sum. 
     The angle Ø may be made more acute or oblique, and, generally, will have greater definition between a Treatment target and collateral tissue in the latter instance, but have a greater maximum power differential in the former instance. It should be noted that the particular types of radiation reflecting, modulating, focusing and diffusing devices pictured in  FIG. 1  are illustrative, but not exhaustive. The particular angles, distances of the radiation propagations, beam splitters, mirrors and other optical devices may be of any suitable choice for reflecting, splitting, delaying or otherwise altering the directions, distances and other aspects of electromagnetic radiation, or otherwise carrying out aspects of the invention. For example, a dual-prism square beam splitter need not be the type of beam splitter used, and the emergent collateral radiation may be accomplished to some degree with a diffusing lens, rather than a complementary opening. Radiation may be amplified at any point or in any area, for example, by optical amplification in a medium (not pictured) or the amounts directed to each beam may be attenuated with amplification of a source beam (or source beams), to correct or optimize the distribution of radiation and allow for constructive and destructive interference of the correct vectors to optimize Protection and Treatment according to aspects of the present invention. Furthermore, it should be understood that many other methods may be used to generate complementary, inverse waves such as those created by the system depicted in  FIG. 1 , and the present invention is in no way limited to the exact techniques explained with respect to  FIG. 1 . For example, multiple emitters may be used and separately controlled and modulated through feedback to yield such interference, rather than splitting an originating beam. However, splitting an originating beam may have some advantages, as well as drawbacks, over other approaches to carry out aspects of the present invention. It is also possible to drive, create, simulate or amplify attenuating Protective radiation (or anti-radiation), for example, by magnetic or electromagnetic amplification or attenuation transmitted or pulsed from the same side as the Treatment beam, and/or from the opposing side, (or vice versa, with respect to the Protection Side), rendering it out-of-phase, causing more attenuated, and otherwise different ionization or other radiation effects in desired areas of Protection coverage. 
     As alluded to above,  FIG. 2  aids in explaining which of the components of the exemplary system depicted in  FIG. 1  are within the Treatment Side or Protective Side of the system. All components within the box encompassing Treatment Side components—box  201 —can be thought of as a part of the Treatment Side of the system. All components within the box encompassing Protective Side components—box  203 —can be thought of as a part of the Protective Side of the system. Components contributing, but not entirely within either the Protective Side or Treatment Side of the system, as shown in  FIG. 2 , include the originating source, shown as  207  in  FIG. 2 , and first beam splitter in the beam sequence, shown as  205 , which may be thought of as present in both system sides. 
       FIG. 3  depicts the same system discussed in  FIGS. 1 and 2 , with additional control hardware and techniques depicted. A control system  381  appears in the upper-right corner of the figure, and may include input  383  and output  385  devices and their connectors and circuitry, which allow the control system to give and receive signals, instructions and information to and from sensors  387  and  389 . Sensor  387  is located within the path of the stream of resulting vector beam  379 , and may sense, among other characteristics, the strength, period, phase, frequency, and amplitude or energy of ambient and/or directional radiation. Sensor  387  passes a signal with any or all of that sensory information by transmission wires/bus  391 . Of course, transmission may be by any suitable means, such as RF signal circuitry and hardware, as well as the pictured hard wiring, but hard wiring is preferred in order to avoid unintentional interference with other aspects of the invention. Sensor  389  also permits the system to sense radiation and any of its sensible characteristics, but, in this instance, is located near the convergence of the leaked Emergent-Slit Radiation  367  and Protective radiation  369 . Based on information received by the system, the system may modulate and tune radiation on both the Treatment Side and the Protective Side of the hardware system with output signals or instructions carried on leads  393  and  395 , to modulator  313  and modulator/blocker  315 . For example, if sensor  389  detects that the Protective radiation  369  is not interfering properly or completely enough, for example, because the resulting wave form is not in a well-defined single standing wave phase, the system may, for example, adjust the energy level, amplitude, phase or polarization of source radiation beam  317 , using modulator  315 , until the leaked radiation and Protective radiation are sensed to properly interfere more completely. Additional sensors (not pictured), including sensors for beams  343  and  345 , might also pass characteristics information regarding any beam, including, but not limited to, the individual source beams contributing to resulting vector beam  379 , and allow the system to tune those characteristics using modulators of each of those streams (not pictured) individually. Control system  381  may also be used to control spatial configuration actuators or servos for any system component, including, but not limited to, 3-dimensional pivot and scissoring device  397 , which may re-orient mirrors  351  and  353  in space—in part, by actuating motorized hinge  354 . The distance and orientation of mirrors  351  and  353 , and any other individual device or hardware item in the system of  FIG. 3  may be further altered with respect to the target  301  and additional system hardware, such as mirror  350 , via telescoping and rotating actuators or servos and/or by mounting other variable component-connecting hardware—for example, a telescoping and rotating servo and hardware between mirror array  351 / 353  and mirror  350 , or an adjustable fixative bracket between mirror  353  and target and collateral clone  363  and  361 . In this way, the control system may adjust hardware to fit targets of varying size and location efficiently and conveniently, and may also adjust the 3-D orientation of hardware to maximize the effectiveness and efficiency of both the Treatment Side and Protective Side of the system, for example, to tune source beams  343 ,  345  and  359  in light of refraction effects or live information attributed to or resulting from the target  301  and collateral Protected material  365 . For example, MRI sensory and imaging information may be taken of the target  301  and collateral Protected material  365  on a live basis through MRI hardware (not pictured) and sent to the control system via leads (not pictured) to input  385 . Based on radiation refractive property models held in, or accessible to, control system  381 , a refractive profile for the target  301  and collateral Protected material  365  may be built, and actual and anticipated radiation from any point around or within the target  301  and collateral Protected material  365  may be compared to data projected by those models. For example, a model such as the MIRD-5 phantom computational body model developed by the Oak Ridge National Laboratory, may be used as a platform and modified by the system, including organ surface refraction, fluorescence and scattering effects. In the event of substantial, sustained deviation from anticipated or projected and actual radiation measurements, adjustments to the refraction models and actuated or controlled system hardware may be made that explain and/or compensate for the deviation. In addition, hardware 3-D orientations and beam characteristics may be adjusted to further compensate for such unexpected, newly learned refractive profile characteristics, thereby optimizing system performance. In addition, the system may exploit natural lensing effects that take place in collateral tissue, to allow diffuse radiation across broader, lensing collateral material to focus radiation on a target volume. 
     Additional Treatment and Protective sources, and/or such sources of greater complexity, with, for example, more radiation source beam origination points, may be introduced into the system to address more complex refraction phenomena profiled than that pictured in  FIGS. 1 through 3 , and to address target, collateral material or other subject- or media-related reflection, blocking and refraction effects. 
     A control system, which may supplement or replace  381 , including some of its user interface options, is described in greater detail in  FIG. 19 . 
     To reduce loss of radiation from conversion of a multi-directional source to a source beam, anamorphic mirror and/or lensing, or holographic techniques, may alternatively be used to recreate a reversed image of the source, or part thereof, in the target volume, as an alternative to the mirror array described in  FIGS. 1-3 . 
       FIG. 4  depicts beam collimating, source orientation and other structural and controlling hardware which may comprise or control radiation sources in accordance with aspects of the present invention. Unlike with  FIGS. 1-3 , the common origination and splitting and reflection of a source beam for multiple sources is not pictured. However, it should be understood that any source pictured in  FIG. 4 , and in other related figures including a radiation source, may be commonly derived from such a master source, as described in  FIGS. 1-3 . Beginning with source  400 , radiation is initially emitted in several directions, exemplified by ray paths  403 . Those ray paths hit a substantially parabolic mirror or reflector/absorber  405 . Because the source radiation origination point  401  is located at the focus point of the parabolic shape of  405 , this leads reflected efferent radiation rays  407  to approach lens element  409  in substantially parallel pathways. However, owing to the natural incoherence and expansion of the plane waves of electromagnetic radiation and otherwise errant particle radiation, collimators, such as multi-leaf collimators  411 , may be used to shape and restrict the total beam of radiation that will enter lens element  409  and, ultimately, exit the hardware after being focused and/or diffused by lens element  409 . Collimators  411 , and lens element  409 , may be real-time 3-D conformational, tailoring the beam&#39;s shape according to MRI or other imaging and sensory feedback and refraction models, as further explained with respect to other aspects of the present invention. 
     Rather than a conventional lens, lens element  409  may be replaced by a new form of lens element better equipped to handle the wear and tear of focusing higher-energy radiation. For example, a lens element with replaceable lens-shaped compartment-bounding elements, and an interstitial refractive and/or cooling fluid, which may circulate in and out of an external chamber(s), such as a bladder or tank, and lead channels, via a pump, to avoid overheating and breakdown, may be added. In addition, the lens-shaped compartment bounding elements may bound just the radiation entry and exit sides of the lens element, and may slide, while still sealing the interstitial fluid from leakage, along at least one side-walling element, which need not be transparent or translucent. As the lens-shaped compartment-bounding elements expand or contract together, they may change their shape to have more or less acute gradations, and different focal effects, by a graduated elastic aspect along their expanse, radiating from their center, and the central chamber may naturally draw in more or less fluid, as a vacuum or positive pressure is built, above the pressure naturally created by the circulation system. The focus may also be changed by electrically-actuated or magnetically-actuated control points on the lens-shaped elements (or magnetically-actuated and orienting elements in the fluid, which change their refractive properties in different magnetically-actuated orientations in space), and may be so numerous as to allow effectively unlimited conformational changes in the lens shape. 
     As explained with reference to  FIG. 19 , below, a control system may instantaneously test 3-D orientation of source or hardware movements or focal lengths and areas and radiation characteristic changes in multiple ways, evaluate improvement or deterioration of Treatment and Protective radiation interference and radiation delivery, such as by test instances, and implement changes according to that feedback. Thereafter, the system may implement further tuning based on additional instantaneous testing and comparison to the results of the previous orientation and beam characteristics to assess improvement. If no overall improvement has been made, the system may revert to the previous orientation and beam characteristics. Among other things, such modulation and focusing of the radiation source may better address target and collateral matter movement, including movements between target and collateral matter. Lens element  409  may either focus or diffuse efferent radiation, depending upon the needs of the system. Lens element  409  may be a single lens, or a complex of lenses and/or parabolic mirror  405  may itself not be perfectly parabolic, with an integrated or derived angle deformation adjustment that diffuses and/or focuses efferent radiation relatively uniformly, or in conformity with a desired Treatment area dosage distribution. For example, the function for the parabola may be modified to result in a unit-by-unit adjustment (e.g., subtract 0.01 millimeters from the x-axis for each function output per millimeter along the y-axis, to cause uniform diffusion or focusing). Such a function might thereby be described as f(y)=(x−0.01y) 2 , for example. Such a pseudo-parabolic mirror could obviate the lens element  409 , which may be omitted. After passing through lens element  409 , the efferent radiation may enter a polarizing and/or modulating filter or filter blocker  413 . Element  413  may permit the source to restrict radiation to one phase, one polarity and one frequency and/or intensity, or a range or ranges thereof, among other characteristics, or a stream, succession or grouping of instances of such characteristics, as may be needed by the system to optimize performance due to interference with other sources and the refraction blocking and reflection characteristics of the target, medium and collateral material of a subject and Protective Radiation, if any. Appropriate radiation emission, or patterns thereof, then exit the source at port  415 . To reduce the risk of leaking radiation, blocking element  417 , variably attached (e.g., by a detachable and conformable ball-and-socket joint  419 ) to the source housing  421 , may be used, which is preferably made of a material or structure or force field that substantially absorbs stray or Fringe Radiation from the source, out-of-line with an intended beam path. Element  417  is preferably a telescoping member comprising matter of high radiation absorptiveness, such as lead, such that different distances between sources, targets, collateral material and media may be physically accommodated. In Treatment configurations with multiple sources, the positioning of blocking members, such as that illustrated as  423  attached to a paired source,  425 . Such accommodating configurations allow for gapless interlocking of the blocking elements, even if telescoped, to prevent or limit stray or unintended peripheral radiation. A literal locking mechanism, such as flexible unisex or multi- or omni-valent latching or other reversible physical binding on every surface of every blocker, which may close any gap between neighboring blocking elements on multiple sources, is preferred. 
       FIG. 5  depicts another exemplary hardware system and associated radiation delivery system and techniques, with multiple sources such as those depicted in  FIGS. 1-4 , which may be used to carry out aspects of the present invention. Treatment-side sources  501  and  503  emit radiation generally from the left-hand side of the figure toward the right-hand side and, more specifically, in the direction indicated by beam lines  505  through  515 . More particularly, the beam of radiation emitted from source  501  is directed toward the lower-right corner of the figure while the beam of radiation emitted from source  503  is directed toward the upper-right corner of the figure. By techniques and mechanisms discussed elsewhere in this application, as above, in connection with  FIG. 4 , the radiation from sources  501  and  503  is preferably in the same phase, of the same or a complementarily superposing polarity (and even more preferably, of a matching chiral pair of polarizations), and the same frequency and intensity, or any one of those characteristics, but, preferably, each of those characteristics. Thus, as discussed earlier in this application, as the cross-sections of the beams of radiation from sources  501  and  503  converge, near or about the volume of a target mass  517 , the radiation vectors sum to resultant superposed beam of greater magnitude and/or a greater or otherwise desired superposition-resulting frequency, or other desired superposition combination, depending on the angle separating the direction of the two sources  501  and  503 , and their beams, whose direction are shown by rays  505  through  509  and  511  through  515 , respectively, and also depending on the magnitude of those Treatment-Side beams. Also by mechanisms and techniques described elsewhere in this application, complementary Protective-Side radiation sources  521  and  523  introduce superposing radiation (preferably of the same frequency, intensity and of appropriate polarity such that it interferes inversely with radiation emanating from Treatment-Side sources (propagating in an at least partially opposing direction in a matching amount in that direction), such as plane wave radiation expanding beyond directional rays  505  through  515 ). In this way, sources  521  and  523  have the net effect of compressing and trimming the effect of fringe or “leaked” radiation expanding beyond the desired Treatment and/or communication target  517 , by greatly reducing the transfer of energy by the Treatment-Side sources to collateral material  519 . Accordingly, sources  521  and  523  may be thought of as Protective-Side components and, more specifically, as Protecting collateral material from fringe radiation on the outer edges of the sources. It should be noted that, in this configuration, Protective outer edge radiation sources  521  and  523  are powered at lower level than their paired Treatment sources  501  and  503 , respectively. More preferably, Protective sources  521  and  523  are outfitted with partially-absorptive filters (not pictured) that reduce the intensity and/or density of the interfering Protective radiation beam if one were to assess the resulting beam/field of Protective radiation moving from directional rays at the edge of the Protective beam nearest the Treatment beam and moving one&#39;s assessment toward the outer edge of those directional rays, by, for example, an assessment sensor passed approximately through a plan bisecting such a beam, the direction of such an assessment path being that shown by arrow  525 . The exact power levels and attrition of the beams laterally or vertically in any rotation orientation of the source, and across any localized plane or volume, may be modulated by an actuated filter and control system (not pictured), and may be adjusted in real time based on sensory feedback concerning the resulting radiation field. For example, if the fringe radiation and Protective radiation are not harmonic, not interfering, not producing standing waves, or are determined to be transferring ionizing radiation that may be further reduced by modulation of either the source radiation or the Protective radiation, the control system may so modulate either the source radiation or the Protective radiation, and with each source, independently, to optimize Treatment and/or Protection given the refraction of collateral material and media, and/or real-time deviation from refractive profiles maintained and adjusted, in the control system. As mentioned previously with respect to other embodiments, instantaneous or other testing, at substantially lower dosages than the majority of the Treatment time, may be used to model and alter 3-D refraction and blocking profiles and models for the target and collateral material. 
     As mentioned previously, the radiation refraction and blocking profiles of targets, collateral material and other media can reduce the effectiveness of paired Treatment sources and Protective sources, which serve to concentrate ionizing radiation, or other, for example, combined signal-carrying radiation, in desired areas. In addition to modifying the intensity and other radiation characteristics emanating from sources, the control system may dictate additional or different ray paths for either the Treatment or Protective sources (and any one or group thereof) by efferent radiation dynamic actuated lenses, filters and/or modifying the number, placement and angle of Protective and Treatment sources to improve the distribution of ionizing and protective radiation, based on refractive/reflective models and live sensory feedback. 
     In any event, preferably, additional Protective Side sources are also used, to also address leaked or fringe radiation on the inner area, between the sides of Protective sources closest to one another. Such additional Protective sources are shown as sources  527 ,  529 ,  531  and  533  which are aimed to Protect collateral material and media from source fringe radiation from that inner area and, preferably, are aimed toward or through the central plane evenly bisecting laterally the Treatment-Side sources and target volume, but at an angle permitting the graduated distribution of Protective radiation to better match fringe radiation with an optimal avoidance of unintentional protective radiation in the target volume. Generally speaking, Protective beam paths aimed tangentially to target structures, at angles more oblique than 90 degrees with respect to the central source and target bisecting plane will be more optimized and require less Protective source power. Unlike Protective beams  521  and  523 , sources  527  through  533  are preferably mounted by hardware (not shown) above and below the central plane bisecting the originating sources  501  and  503  and the Treatment target  517 , such that a lower amount of Protective radiation passes through the target. Because Protective sources  527 - 529  are above and below that central plane, their beam paths may cross over and under the target, thereby partially Protecting fringe radiation in those areas as well, which Protective beams  521  and  523  cannot do as effectively. 
     It should be noted that, although it is preferred that Treatment Side sources emit electromagnetic radiation or other energy-transmitting waves of the same polarity, period and frequency, it may be preferable, in some embodiments, to use a different or more random polarity, period or frequency. For example, to create a superposed frequency that is greater (which may be advantageous for creating a different, increased electromagnetic energy level, waves of a different period, and even different frequencies, may be used. Oscillating, different frequencies, brought together, may also create patterns of increased energy, or energy spikes, that are advantageous, to destroy cells that move with a cyclical biological process (e.g., breathing, heartbeat). 
       FIG. 6  is a perspective view illustration of a device comprised of a structural array of multiple Protective Side and Treatment Side sources, demonstrating the operation of preferred embodiments of the present invention in 3-D space. Device  601  is depicted generally as a ring structure, with Treatment sources  603  and  605  generally facing a viewer of the figure, as well as the inside of the ring structure on the opposing side, preferably, focusing their efferent radiation on a target toward the center of the ring structure (e.g., a cancerous tumor target within a patient laying on a bed inserted into the ring structure.). Sources  607  and  611  emit Protective radiation, according to aspects of the present invention described above, from the outer edges of beam paths from sources  603  and  605  and outward from the center of the ring, thereby reducing fringe radiation, expanding beyond the desired beam paths for sources  603  and  605 . Radiation-diffusing and edged surface coating  613  may line the inner surface of the ring structure, absorbing and/or reflecting away radiation emanating from sources that has already passed through the target volume of the ring structure and hit the inner surface of the ring structure, and preventing the majority of that radiation from re-entering the collateral area surrounding a target. Although not pictured, such surface coating may cover any other structure that may create undesired reflections. In addition to diffusing edges, surface coating  613  may also have downward-facing facets, to further absorb and reflect radiation reflecting on lower, upward-facing facets of the coating. 
     The lenses of all sources shown in  FIG. 6  are not simple spherical or parabolic shapes. Rather, they illustrate a more desirable multifunctional and/or 3-D conformational blend of shapes, leading to improved shaped radiation beams. For example, Protective source  609  extends more greatly above and below the plane bisecting ring structure  601  into two equal, uniformly-shaped rings than other sources, and as its structure reaches inward both above and below that plane, the width of the source increases. Thus, source  609  is capable of generating a greater density of radiation, from a greater distribution of angles and yet at angles that still conform with the edges of the beam paths from sources  603  and  605 , despite the change in distance. Ray paths from source  609  preferably converge just beyond (viewing from the perspective of the drawing) the convergence of ray paths from the Treatment sources, thereby attenuating Fringe Radiation where it is greatest. Alternatively, the protective beam paths of source  609  may face outward from the center of the source head, by a shape or other mechanism aiming its edges along the edges of ionizing source radiation, which, itself, preferably converges on the leading volumetric features of the target. Controllable, graduated modulators or filters may adjust radiation emanating from different regions of sources. For example, source  609  may adjust phase, period, frequency, intensity, amplitude and other characteristics to maximize Protective interference across the beam profile, as it crosses leaked Fringe radiation from the Treatment sources. Other sources, by contrast, may capitalize on additional lateral space, along the ring structure, thereby becoming more ovoid, or a blend with another curved or graduated structure and the primary beam-shaping structure (e.g., parabola or decaying parabola, as discussed with respect to  FIG. 4 ), allowing for a greater number of convergent angles, more diffused across collateral structure and media space. 
     In another embodiment, ring structure  601  may be split into two or more complementary beam structures, rather than one (such as the ring structure pictured), with overlapping regions coated, such as with coating  613 . In such an embodiment, the ray paths may be adjustable to accommodate differing distances between the sources, as they are brought closer or further apart—for example, by flexible, uniform bending of the multiple, complementary semi-ring structures, of the sources alone or by actuation of lens or reflector controls by a control system, such as the control system discussed in connection with  FIG. 19 . All of the same control system and other features and aspects discussed with respect to systems depicted in  FIGS. 1-5  are also possible with respect to  FIG. 6 . 
       FIG. 7  is a graphical depiction of radiation sources delivering targeted controlled-length pulses of radiation, according to aspects of the present invention. Sources  703  and  705  are each facing, and placed on opposing sides of, a radiation Treatment target volume  707 , and its collateral volume  711 . Two exemplary pulses of radiation, each a produced increased concentration of radiation of a particular width, once emitted, are depicted, if they have yet been created by a source, at instances of time indicated by point-in-time-associated time/location indicators  715 ,  717 ,  719 ,  721  and  723 —with notations T 1 , T 2 , T 3 , T 4 , and T 5 , respectively—which are placed directly below depictions of the location of Pulse  701  or  702 , or both Pulse  701  and  702 , at the instances of time indicated. Source  703 , on the right-hand side of the figure, produces the first of these two pulses, which is therefore referred to as Pulse  701 . Pulse  702  is emitted at a later time than pulse  701 , by system source  705 , depicted on the left-hand side of the figure. The widths of Pulse  701  and Pulse  702  are shown as identical, and approximately matching the diameter of the target volume and the width of the collateral material through which it may pass, on either side of the target. In practice, these widths will not and need not perfectly match to carry out aspects of the present invention, and widths of the pulses need not exactly match the width of the target or collateral material through which they penetrate. For example, if the width of the collateral material is prioritized and/or keyed by the system, Protection area path-width directed pulses may be used such that the opposing beams overlap more completely at an instant of time in the collateral material area  713 , while ensuring that no Protection or substantially no Protection occurs in the target area. Following the overlap/superposition period of time, in any approach, some ionizing radiation, albeit a lesser amount, will occur in the collateral Protection area  713 , while the two pulses are not in the instant of perfectly matched overlap. Similarly, and preferably, a target-width influenced and/or keyed length and timed pulse may be used by at least one of the sources, or from both sources. Again, the pulses would be timed to intersect before or after the target, and, preferably, the instances of overlap for different pulse pairs would be at different, distributed points in the collateral Protection area, to more evenly distribute their Protection through that mass. Preferably, a distributable common denominator or factor of the target/radiation intersection path and its associated collateral matter intersection path is used and, more preferably, a small enough denominator or factor to allow even distribution of Protective superposition over a greater volume of collateral material. Protection can happen on both sides of the target mass or volume  707 . After the first pulse pair, it is preferred that a new pulse follows, in the same relative timing as between the first pulse pair, and such that protective superposition again occurs on the opposite side of the target, and so on for additional pulses, from alternating sides, in similar timing, but preferably adjusted to distribute protection evenly across the collateral protection areas. 
     It should be noted that point-in-time-associated time/location indicators  715 ,  717 ,  719 ,  721  and  723 —with notations T 1 , T 2 , T 3 , T 4 , and T 5 —are relatively evenly spaced apart in time, but are preferably in increments necessary to achieve the relative locations indicated and discussed, given that the distances involved with a particular target mass and collateral area needing Protection. Preferably, a refraction model is also used by the system, allowing for correct timing and angles, which model may be tuned by the system according to live feedback (e.g., infra-red sensory data for indicating whether heating associated with ionizing energy is present) indicating whether Protective superposition is failing or not optimal. 
       FIG. 8  is a side-view of aspects comprised in an informational storage system and media implementing aspects of the present invention. Directable radiation sources  801  and  803  may direct beams of radiation along any of paired vector paths  805 ,  807 ,  809  or  811  (source  801  being capable of directing beams along the half of the paired vectors projecting from the upper left-hand side toward the lower right-hand side, and source  803  capable of directing beams along the half of the paired vectors projecting from the upper-right hand side toward the lower-left hand side of the figure). A multi-component readable and/or writable media  815  lies within the paired vector paths  805 - 811 . Preferably, the paired vector paths  805 - 811  converge at or about the leading volume or features of media components,  817 - 821 , currently being written or read by the system. Media components neighboring  817 - 821 , which are not currently being written or read, are depicted with dashed lines, signifying their inactive state, because they are not the main focus of the figure. As discussed previously in this application, aspects of the present invention allow the converging pairs of radiation beams to vector sum and/or superpose with one another, with a net vector and/or changed frequency or other resulting characteristic centered along a resulting vector line  822 , and in a direction toward the bottom of the figure. However, the source vectors which are, by themselves, weaker than their resulting vector, alone will pass through certain of the neighboring media components. As a result, a resulting vector may be sufficient to impart a greater effect, such as imparting a charge or charge differential, as in a changed magnetic condition or state, or causing a chemical reaction or photon amplitude-dependent effects in the media component through which it first passes, while being insufficient to impart the same effect on neighboring components. Such effects may be relatively transient, permanent, and/or readable by the system, depending on the media components selected. Wide enough source angles, such as those shown for components  817  and  819 , along with a reflective or semi-reflective surface just above the convergence points of the summing vectors, may permit components within the path of the resulting vector, which are further downstream than the component targeted by a vector pair, to avoid reaching a critical affected energy as well. However, it is also possible, and with certain advantages such as cost of manufacturing, to optimize the array of media component sizes and reactivity (e.g., chargeable cells) and/or beam targeting angles and strengths, such that the naturally increasing vector sum percentage, balanced by the natural spreading and scattering of radiation the beam used, causes the read or write reaction to occur in the cell in which the beams converge, but not in any neighboring cell. Even more preferably, however, the reaction and charge differential leading to a read or write event within a media component is based at least partially on a local differential with neighboring media components. In other words, only when the resulting vector beam energy is both above a threshold and significantly greater than its neighbors, will the read or write event occur in that media component. This arrangement can be achieved, among other ways, by a writing event triggered by a charge diffusion (efflux) gate. 
     To illustrate the nature of the naturally increasing vector percentage in the instance of in-phase amplitude superposition, mentioned immediately above, as pictured, vectors  805  converge with an angle, shown as ø 1  ( 823 ), of 63.43 degrees, which results in a vector sum (of its resulting superposed beam) that is 89.46 percent of either of the two even source vectors at the point of convergence. Assuming that the neighboring media components are tuned to the same combined wave critical reaction energy (or activation energy) for a read/write event, just below (but significantly below) the energy level of each source vector alone, the individual source vectors generally would need to lose slightly more than 10.54 percent of their passage across the upper corners of media component  817 , to avoid an inadvertent read or write event in the neighboring components, assuming that no additional reflecting, refracting or absorbing features are also included along such stray vector paths from neighboring component activation, which additional features may be desirable to omit for cost reasons. An appropriate media and beam type, causing sufficient radiation scattering and absorption, could be chosen for that purpose. Alternatively, or in addition, a central reacting element, such as an antenna located in the center of a cellular media component, could be missed by the majority or a critical amount of such pass-through source vectors in the neighboring media components. Also alternatively, the media component cells could be other than square-shaped, or otherwise have facets that aid in reflecting or scattering vectors that do not proceed in the direction of the resulting combination centered on the line of the targeted media component&#39;s column,  822 . In any event, however, the resulting vector itself must decrease in force as it proceeds to the next media component below the target media component, or the next media component (or, row thereof) below the target media component must be tuned to a higher reaction energy, to avoid an inadvertent read/write event. In this latter instance, the greater percentage sum of resulting vectors as convergence events proceed downward, for deeper read or write events, naturally aids in utilizing such higher reaction energies. But if the system utilizes the natural attrition of a radiation beam from scattering alone, a critical distance may be required from the sources to the first useable media row, such that the decrease in beam strength due to scattering and absorption may be balanced by the increasing resulting vector strength percentage allows a reaction that is within a range of source vectors that do not inadvertently cause a read or write event in cells other than the targeted cell. For example, if square media component cells are used, the distances shown for media component cells  819 ,  820  and  821  may be sufficient relative to the source separation, because the resulting summed vectors of the same strength beam would be 141.4 percent of the source beams at convergence for the beams converging at ø 2 , 166.4 percent for the beams converging ø 3  (or, 17.58 percent more vector sum percentage) and 178.9 percent for the beams converging ø 4  (or, 7.512 percent more vector sum percentage over the sum at ø 3 ), Meanwhile, the source beam lengths (their distances traveled) increase 27.4 percent and 24.1 percent over the same two intervals, as determined by Pythagorean theorem. While these latter intervals, in source beam length, are greater, generally, the semi-exponential attrition due to beam scattering and absorption may be used to exaggerate or decrease the effect of those intervals. Using a beam and media type with a reverse square attrition due to distance, for example, the first interval results in a 38.4 percent decrease and the second interval results in a 35 percent decrease in beam strength due to scattering/absorption. To compensate for this difference, deeper tiers of levels of the media can be made more sensitive in their reaction energy or activation energy, such that they are activated despite the greater attrition to vector sum resultant vector ratio at those tiers. Alternatively, a medium and source beam with a more favorable attrition-with-distance profile may be chosen, than the example just discussed, which depletes with the inverse square of the distance from the source. As another approach, localized and/or periodic optical or other amplification may be used at points along the beam paths, to bring the attrition and vector summing into balance for activating individual cells. As another option, media component or cell length may increase as tiers/rows deepen (away from the source), with or without cell size fanning out and becoming wider horizontally, which is another alternative configuration, to allow a greater build-up of net affecting charge, or other reaction, in deeper cells. This aspect is demonstrated, among others, in more detail, in  FIG. 9 , below. 
     Depending on the nature of the media selected and the characteristics of its comprised elements, such as their refractive index and radiation scattering and absorption characteristics, optimized media components sizes and shapes may be selected that allow the activation of the media component or components targeted by converging wave beams, without inadvertently activating neighboring media components. 
     It should be noted that either the media or the sources may rotate around a central axis, or, to avoid moving parts, both may remain stationary while the strengths of sources vary to create the requisite vector sum at any media component targeted by vector convergence. Multiple sources, other than two, may also be used to increase selectivity of the appropriate media component(s) for a read-write event. In any event, it is preferred that the cells take on a concentered configuration, and that they be shaped for such concentricity, as further illustrated in  FIG. 9 . 
       FIG. 9  depicts comprised parts of a storage medium and system according to aspects of the present invention. As with the system discussed with respect to  FIG. 8 , the system discussed with respect to  FIG. 9  includes directable or directed electromagnetic radiation sources (in this instance,  901  and  903 ), and which may direct beams of radiation along any of paired vector paths  905 ,  907 , or  909 , among other pairings (not pictured) for read or write activities at deeper levels, away from the center between the sources (some of which levels are also, not pictured). As with the analogous sources in  FIG. 8 , source  901  is capable of directing beams along the half of the paired vectors projecting from the upper left-hand side toward the lower right-hand side, and source  903  is capable of directing beams along the half of the paired vectors projecting from the upper-right hand side toward the lower-left hand side of the figure. However,  FIG. 9  further illustrates several additional aspects of the present invention, only some of which were discussed above, with respect to  FIG. 8 . First, sources  901  and  903  may be swiveled, as a pair, along a circular path for their mounting, with respect to its circular grid array of media components  915 , which also point radially outward from the center between the sources. A computer system (not pictured) may direct an actuator (also not pictured) to swivel either the sources on their mounting or the grid array on their mounting, in appropriate stopping points to allow the sources to evenly address the center of the leading volume of a row of grid components, which may then be considered active, such as shown active row of media components  917 . A sensor,  927 , may be used for both reading and writing confirmation readings, which indicate the read/written condition of a media component. Specifically, when a component has been written by the system, a charge density or other reaction condition may be detectable by return radiation which reflects directly back from each surface between individual media components (shown as three per row, in this instance), and therefore passes back through the media in that cell. This configuration permits the sources to remain in a semi-fixed orientation with respect to one another, while permitting the reading of a wide variety of media cells. A greater density of smaller media component cells than that pictured may be used, including smaller cell rows in greater numbers and at more angles, and/or with additional sets into the page, i.e., along a z-axis of the figure (preferably, serial with the previous set, by a single strand, spiral configuration, may be used, to allow infinitely expandable storage, particularly with spiral add-on units that may be fastened together, to lengthen the spiral). In this instance, an actuating mechanism for both spinning and drawing the media with respect to the sensor and source array should be used. A spherical array may also be used by simply extending the array, as it is shown in  FIG. 9 , in three dimensions, in which case the sensor source center piece may be spherical, rather than circular. Alternatively, sensors may be placed on the far side of a row of media components, among other possibilities, in addition to or instead of the location shown for sensor  927 , and may be fixed in position relative to the mounting for the sources. In that instance, reflection back by media components is not required for read/write scanning/confirmation. 
       FIGS. 10-15  relate to a system implementing aspects of the present invention related to encryption and decryption of message or information-carrying waves, such as electromagnetic radiation. To implement these aspects, information-carrying modulation of waves is used. Preferably, and as demonstrated in the figures, amplitude modulation of two carrier source waves is used, but it should be understood that any form of wave modulation to carry information may be used, including, but not limited to, frequency modulation, period modulation, polarization modulation, a type of modulation based on the instantaneous and potentially infinite warping of the direction of an electromagnetic sine wave at any point or the derivation or integration of all such points, and any number of source waves may be used. 
       FIG. 10  is a graphical depiction of an example wave amplitude modulation alphabet which may be implemented in a modulated carrier source wave that may be used in certain encryption/decryption aspects of the present invention. A carrier wave, preferably of a substantially constant amplitude, frequency, polarization (especially in comparison to any of the Encrypted Source Beam waves generated by the system, such that these characteristics are in common with each source wave encrypted and/or decrypted by the system) may be provided by the system. Part of a such a carrier wave is shown as  1001 , and a ruler  1003  with dashed line  1004  which measures the crest (the amplitude, or substantial highest concentration of particles, or particle location probabilities, depending on the type of wave used) are depicted. The ruler  1003  also depicts various possible levels of amplitude modulation of the carrier wave, at tick points (for example, tick points  1002 ) corresponding with amplitude levels 1 through 7 (the level of the second tick point or level up from the bottom of the ruler being twice the amplitude level of the first, and the level of the third tick/level up from the bottom of the ruler being three times the amplitude level of tick/level 1, and so on.) The potential amplitudes of such a modulated wave are demonstrated by wave sections  1005 ,  1007 ,  1009 ,  1011 ,  1013 ,  1015  and  1017 , each of which corresponds to one, and only one, of the ruler tick points. Including the level of the unmodulated carrier wave, the depicted modulation alphabet for one source wave therefore comprises 7 units (symbols or keys) which may be output in a modulated source wave. For convenience, we may refer to amplitude modulation levels  1005 ,  1007 ,  1009 ,  1011 ,  1013 ,  1015  and  1017  as energy or amplitude levels/symbols 1, 2, 3, 4, 5, 6 and 7, respectively, each matching a tick/level on the ruler. It should be understood that, although an amplitude modulation alphabet is pictured as an example, any form of wave modulation to communicate data may be used, alternatively or in addition to the amplitude modulation example pictured. 
       FIG. 11  is a graphical depiction of an example modulated source signal  1101 , generated by the carrier beam, and using the alphabet of  FIG. 10 . Modulated source signal  1101  is modulated at particular regions  1103 ,  1105 ,  1107 ,  1109 ,  1111  and  1113 . In this instance, one may see, with reference to the modulation levels discussed with reference to  FIG. 10 , that, reading from right to left (from  1113  to  1103 ), that the modulated source signal comprises the following symbols, in the following order: amplitude level/symbols 5, 4, 3, 7, 6, 7. 
       FIG. 12  is a graphical depiction of another example modulated source signal  1201 , generated by a substantially identical carrier beam as used in  FIG. 11 , and also using the symbol alphabet of  FIG. 10 . Modulated source signal  1201  is modulated at particular regions  1203 ,  1205 ,  1207 ,  1209 ,  1211  and  1213 . In this instance, one may see, with reference to the modulation levels discussed with reference to  FIG. 10 , that, reading from right to left (from  1213  to  1203 ), the modulated source signal comprises the following symbols, in the following order: amplitude level/symbols 1, 6, 6, 4, 2, 3. 
       FIG. 13  is a graphical depiction of an example of a resulting wave amplitude modulation symbol alphabet, resulting from the combination of multiple (in this instance 2) Encrypted Source Beam waves. As will be explained in greater detail, with respect to  FIG. 15 , a system in accordance with aspects of the present invention may cause 2 modulated source waves, such as those discussed with respect to  FIGS. 11 and 12 , to converge at a particular point, region, angle, period and timing such that, as they converge at a particular point or region, they generate a superposed vector sum of a resultant wave that is in phase with the each of the two source waves, which are, themselves, in phase. In the instance of the symbol alphabet depicted in  FIG. 13 , the angle of convergence may be 45 degrees, with the source beams of equal strength, converging at the strengths depicted in  FIGS. 11 and 12 . As a result, the vector sum of the two constituent source waves would be approximately 71 percent, if each were unmodulated, or 35.5 percent of whatever modulated power level each source wave contains. Given that each source wave, in the instance of a two-source wave encryption/decryption language and system, has 7 symbol/power levels, a resulting alphabet for a resulting, decrypted and vector summed wave will have 13 possible symbols/power levels, including the level obtained by 2 unmodified carrier source waves. (Namely, the resultant amplitude alphabet will be from the minimum combination of two source wave level-1 symbols (which we may call level 2 of the resultant wave in terms of power level, but level 1 in terms of the resultant wave lexicon) and a maximum combination of two level-7 source wave symbols (which we may call level 14 in terms of power level, but level 13 in terms of the resultant wave lexicon.) The result of what the two unmodulated carrier source waves would be is shown as resultant carrier combination  1301 . A ruler  1303  depicts 14 evenly-divided power levels at ticks (such as  1302 ), 13 of which, as discussed above, are possible resulting power levels and symbols, which are shown as wave sections  1305 ,  1307 ,  1309 ,  1311 ,  1313 ,  1315 ,  1317 ,  1319 ,  1321 ,  1323 ,  1325 ,  1327  and  1329 , each of which corresponds to one, and only one, of the ruler tick points. As discussed above, wave section  1305  corresponds with the combination and superposition of two level-1 source wave sections. Wave section  1307  corresponds with the combination of one level-1 source wave section and one level-2 source wave section, and so on, exhausting each in-phase superposition possibility. 
     The symbols to be employed by a control system implementing aspects of the present invention may be selected for delivery at a target location in accordance with a varied, randomly-generated or semi-randomly-generated combination algorithm. In other words, instances of the same symbol in a resultant signal can be achieved by an unlimited variety of source symbol combinations selected by the control system, each of which is selected to sum to the desired resultant symbol at the target location. The control system may be programmed with an algorithm assigning various, preferably different and non-repeating source symbol combinations to make hacking impossible. Fractional or even source levels may be assigned to generate the source and resultant signals to yield a greater number of possible combinations. More than two sources may also be used, yielding even stronger encryption, with three or more source symbols superposing in a manner planned by the system at the target to yield the same resultant alphabet. The combination algorithm may be more complex, and difficult to hack, using more sources. 
     The location-based encryption methods discussed herein can be used in combination with other forms of encryption, for example, by use of a shared key or cipher to further encode the resultant signal. The same control system may be used to apply each layer of encryption. 
       FIG. 14  is a graphical depiction of an example resultant signal, that might be generated by the two example modulated carrier beams of  FIGS. 11 and 12 , and implementing the alphabet, of  FIG. 13 . As a result, combining Encrypted Source Beam waves  1101  and  1201 , assuming all of the necessary identical conditions discussed above, results in resulting wave pattern  1401 . From right to left, the now combined and decrypted word, phrase or other packet of symbols comprises the following symbols, in the following order: amplitude level/symbols (from the possible resultant alphabet of  FIG. 13 : amplitude level/symbols: 6, 10, 9, 11, 8, 10. 
     Through a separate encryption process (not pictured) such a resultant, unencrypted phrase may be broken down randomly by a computer hardware and software system into random factors or subtraction results, within the integers permitted by the source alphabet, and then may be used to modulate the source carrier waves in an encryption process that is difficult to break, except within the intended recipient area targeted by the Encrypted Source Beam wave vectors. 
       FIG. 15  is a graphical depiction of a part of an example radio frequency signal modulation, encryption, transmission, receiver and decryption system, in accordance with aspects of the present invention. In this example, directional wave transmission broadcast antennas  1507  and  1509  may broadcast waves of the same period, polarization and other important characteristics for carrying out superposition aspects of the present invention, as discussed elsewhere in this application. Source waves  1511  and  1512  may be substantially identical to the waves depicted and discussed with respect to  FIGS. 11 and 12 , and may be aimed as shown by the directional antenna sources  1507  and  1509 , such that they substantially converge at a point  1501 , at an angle ø,  1503 , which, in this instance, is 45 degrees, as was the case in  FIGS. 1-3 . As a result, and as discussed with respect to  FIGS. 13 and 14 , their resulting vector sum is a Decrypted Result Beam wave substantially identical to that shown in  FIG. 14 , and shown in  FIG. 15  as  1505 . Using aspects of the present invention, if the location of a desired receiving area is known, a known array of transmission or other wave sources, such as  1507  and  1509 , can be oriented by a computer system to transmit randomized source alphabet components to that desired receiving area, such that they create the decrypted vector sum signal in that area only. Although a simple, even spatial division is shown in  FIG. 15 , it is also possible to adjust the encrypted transmission for any distance by initiating the wave from the more distant location earlier, by the correct amount of time such that its transmission across the distance to the receiving area is simultaneous with the transmission from another, closer source. Power levels may also be appropriately adjusted, such that the desired or necessary combination levels are achieved. Any number of alternative source and resultant alphabets may also be used, and source alphabets may be unevenly applied to result in the correct resultant wave language at given distances and transmission and receiving locations. 
     Rather than rely on the correct alignment of two Encrypted Source Beam waves perfectly converging at the intended receiving and decryption superposition target, a variety of spaced, identical different Encrypted Source Beam waves may be aimed at the receiving area, which may be at a variety of angles to cover the location and orientation of the intended receiving/decryption hardware. Using this technique, regardless of the perfection of in-phase superposition in any one instance of wave convergence, at least one such set of superposing vectors will correctly sum to a valid combination, as may be quickly determined and selected for translation into a message by a receiving device, based on whether isolated symbols of the correct proportions are being received, matching a valid decryption vector sum library, such as that described with respect to  FIG. 12 . 
     The system may, alternatively, receive just one Encrypted Source Beam wave which, when combined properly with a known second Encrypted Source Beam wave form, which may be regenerated locally, by the receiving hardware, yields a Decrypted Result Beam. 
       FIG. 16  depicts the head and brain of a human medical patient, and another exemplary hardware system carrying out aspects of the present invention related to radiation delivery. Although the context of patient Treatment is given for  FIGS. 16 through 18  and certain other figures, it should be understood that any target for ionizing or other critical energy level targets or subjects, with collateral structures and media, may be Treated in similar ways according to most aspects of the present invention. In  FIG. 16 , target volume  1601  is to be subjected to ionizing radiation. Examples of such targets include, but are not limited to, malignant or benign tumors and neurological source structures for undesired tremors or seizures. Directable radiation sources  1603  and  1605  each face the patient&#39;s cranium, within which the target volume is embedded, and each radiation source may focus a radiation beam on parts of the target  1601 , irradiating it simultaneously. Also pictured is a relatively important, healthy area of the subject&#39;s brain,  1607 , nearby the target tumor. A physician and/or analytical system may have determined that  1607  is especially important to the patient&#39;s health and function, in comparison with other nearby regions of the brain. As will be explained in greater detail with respect to  FIG. 17 , due to  1607 , and other relatively important structures, there may be no easy, straight-line path from a source, such as  1603 , to a target area, such as  1601 . However, magnetic or electrostatic field generators  1609  and  1611  may be used to create magnetic and/or electrostatic fields of multiple different side-by-side orientations, which may even be directly opposed from one region to another. Preferably, magnetic and/or electrostatic field generators  1609  and  1611  work in conjunction with one another, as shown, reinforcing the desired characteristics of desired magnetic and/or electrostatic fields in the patient. A control system  1613 , such as the system discussed in greater detail with respect to  FIG. 19 , may command magnetic and/or electrostatic field generators  1609  and  1611 , and their individually actuable regions, to generate the characteristics of the desired magnetic and/or electrostatic fields. In addition, local charging units  1615  and  1617  may be used, and controlled by control system  1615 , to impart a local charge differential on nearby or targeted areas, as by passing off electrons into the tissues or drawing electrons from tissues towards them, for example, by conduction or creating a dipole, with the same net charge, in the tissue, but with localized regions of increased positive or negative charge. Although  FIG. 17  depicts two instances each of radiation sources, magnetic and/or electrostatic field generators and charging units, it should be understood that a wide range of device arrays may be used to carry out aspects of the present invention. For example, anywhere from 1 to infinity charging units, of any conformational shape, may be used. In addition, if particle therapy is used, a single radiation source may be used or, an infinite number of sources in a complementary spatial array, such as a concentric focal array, may be used with any form of ionizing radiation for carrying out many aspects of the present invention. Similarly, a single, wrap-around magnetic or electrostatic field generator device(s) or unit(s) may be used, or many multiple instances of such generators, dedicated to generating different magnetic field lines in different regions of the subject which may be curved or otherwise shaped differently than the straight-path fields depicted in  FIG. 16 , while still directing radiation toward intended targets and around structures that need protection from radiation energy transfer. 
     Turning to  FIG. 17 , the significance of the electrostatic and magnetic fields and charge differentials generated by aspects of the invention discussed with reference to  FIG. 16  can be better understood in the context of further aspects of the invention.  FIG. 17  depicts a partial view of the same human patient subject discussed with respect to  FIG. 16 , including a detailed outline of a structural target within the brain of the human patient. In addition,  FIG. 17  depicts a sequence of exemplary particle radiation conditions that may be controlled and monitored in accordance with aspects of the present invention. The right hemisphere  1701  of the patient&#39;s brain is included in  FIG. 17 , and shown in greater detail than in  FIG. 16 . The target region volume is shown in greater detail as well, as  1703 . A critical healthy structure of brain material, to be Protected from ionizing radiation, is shown as  1705 . A particle emitted by a beam of particle radiation, with a particular charge, such as a proton, is shown at different positions over time as  1719  through  1731 , and passes through magnetic and/or electrostatic field lines  1707 - 1717 .  1719  through  1731  illustrate the charged particle&#39;s location at even time intervals, and therefore, map its trajectory through the patient&#39;s brain, which trajectory is, generally, from the left-hand side of the figure toward the right-hand side of the  figure. 1719  depicts the location of the positively-charged particle, such as a proton, at the first point in time considered by the figure, which point in time may be called T 1 . Progressing to the second point in time, the same particle&#39;s position is illustrated an instant later (i.e., the amount of time it takes the particle to travel the distance depicted, which is about 1 centimeter at its current speed, at about 30 to 40% of the speed of light), at a point in time that we may call T 2  (shown as particle location  1721 ). As can be seen by the relatively constant vertical position of the particle between positions  1719  and  1721 , the particle&#39;s initial velocity, at T 1  is almost entirely in a horizontal direction, toward the right-hand side of the figure. However, at particle location  1721 , the particle proceeds into an electric and/or magnetic field, depicted by electrostatic and/or magnetic field line  1707 , which flows generally from the top to the bottom of the figure. By convention, the electrostatic and magnetic fields are depicted by arrows showing the direction of force that would be applied to a positively charged particle at the location of the arrows. Thus, because electrostatic and/or magnetic field line  1707  flows from the top of the figure, toward the bottom of the figure, the positively charged particle begins to accelerate in that direction, and its path begins to curve around the critical brain component  1705 , as dictated by the system, optionally, with magnetic field tuning based on live feedback concerning the particle, the stream of related particles&#39; path from the same source. As the particle continues to proceed generally from the left to the right-hand side of the figure, and arrives at position  1723 , it again is immersed in an electrostatic and/or electromagnetic field line that forces it downward, its acceleration in that direction continues, and its partial velocity in that direction builds further. As the particle continues to progress at a relatively constant horizontal velocity, and maneuvers around critical feature  1705 , it enters a reversed electrostatic or magnetic field at point  1725 , as shown by line  1711 , which flows from the bottom to the top of the page. At this point, the particle&#39;s downward velocity has accumulated appreciably, and the reversed field indicated by magnetic line or electrostatic field line  1711  begins to decrease, but does not yet immediately arrest, that vertical downward velocity component. As a result, the particle continues to curve around critical feature  1705 , as planned by physical models incorporated in the system&#39;s Treatment plan, based on the mass and electromagnetic properties of both the fields and the particles. As the particle approaches location  1727 , it remains in an electrostatic and/or electromagnetic field flowing vertically from the bottom to the top of the page. At this point, the particle has successfully circumnavigated the widest point downward, vertically, of critical feature  1705  and the particle reaches the apex of its curve as its downward vertical velocity is reduced toward zero by the electrostatic and/or magnetic field. Next, the particle proceeds to gain a partially upward velocity by continued acceleration of the electrostatic and/or magnetic field, which continues to flow in that direction, at position point  1729 . At this point, the particle may be thought of as starting to steer toward the target location  1703 , while continuing to curve around critical feature  1705 , which is Protected from the otherwise straight-line path of the particle. To further assist in attraction to the correct target location, a charging device (not pictured) such as charger  1617  from  FIG. 16 , may impart a negative charge on structures near, and to the upper-right hand side of target  1703 , by, for example, conducting electrons into tissue in that region. By positional point  1731 , the particle flows into the target volume, while continuing to accelerate upward. While this may be desired to ensure that the greatest possible amount of target material lies in the particle&#39;s path, increasing the likelihood that it will ionize material there, for example, at the end of a Bragg curve, it may also or otherwise be desirable to alter the electrostatic and/or electromagnetic field upon entering the target, such that the path becomes further curved and, preferably, spiral—which spiral path turns inward or otherwise is confined against exiting the target material until ionization has occurred in target volume  1703 . 
       FIG. 18  also depicts a detailed outline of a structural target within the brain of a human patient, and depicts another sequence of exemplary radiation conditions that may be controlled or monitored according to aspects of the present invention. More specifically,  FIG. 18  depicts two beam waves of ionizing electromagnetic radiation,  1801  and  1803 , emanating from opposing directions, with the same period, preferably in counter-phase (180 degrees out-of-phase), and emanating from their sources with the same relative polarization and amplitude. Electrostatic and/or electromagnetic fields are again created by magnetic and/or electrostatic field generators, such as  1609  and  1611  depicted in  FIG. 16 , and create two discrete, exactly opposed electromagnetic fields: 1) an electromagnetic field applied upon the left edge where beam  1803  enters the target volume  1805  and/or exits critical structure  1807 , and 2) an electromagnetic field applied upon the right edge where beam  1801  enters the target volume  1805  and or exits its collateral brain structures to the right. The former of these fields is described by electrostatic or electromagnetic field line  1809 , and the latter of these fields is depicted by electrostatic or electromagnetic field line  1811 . In this way, because electromagnetic waves shift their polarization when passing through a medium when subject to an externally-applied magnetic field (a magneto-optic effect), opposing, matched waves may better counter one another on either side of the target volume, creating a more effective standing wave that does not transfer ionizing radiation, but each wave entering the field at one edge of the target volume is brought out of phase with the opposing wave while passing through the target region, and may be brought back into the same polarization to again Protect collateral material upon exit at the other end of the target volume by the opposite magnetic and/or electrostatic field on the other side of the target volume. Simultaneously, the same fields may bring the two waves back into phase upon exit, by reversing the process that brought each of them out of phase upon entrance. Additional sensors (not pictured) may test, or periodically test, interference levels in the collateral tissues, by testing methods discussed elsewhere in this application, and adjust characteristics of the fields or sources (or add or adjust instances of them) to optimize Protective interference in the collateral material, especially, critical regions, and ionizing radiation in the target. 
     Magneto-optic effects may also be used in conjunction with other aspects of the present invention, such as those aspects discussed in relation to  FIG. 5 , to slow the propagation of the Treatment Beam of one source, with beam waves of one chirality, as it passes through the medium and magnetic field, in comparison to a Treatment Beam from another source, with waves of the opposite chirality. In this way, the two waves may be initially out-of-phase, when passing through collateral or critical structures, and then brought in phase when passing into a target structure. 
     In any radiation source configuration covered in this application where, as in the aspects covered in  FIG. 18 , two sources face one another and deliver pulses of energy substantially toward one another, other aspects may be used to protect each source from radiation emanating from the source opposing it—such as a variable shielding. Preferably, an absorptive shutter, which is absorptive on the side facing the radiation from the opposing source, closes at the correct time and for the correct duration to absorb any pulse received from the opposing source, and then re-opens to allow the source with the actuated shutter to emit its own pulse. The timing may be orchestrated and adjusted based on feedback from sensors indicating whether opposing radiation is properly blocked. Alternatively, or in addition to such shielding, the sources themselves may avoid such opposing radiation by movement—for example, a juke to dodge the arrival of an opposing pulse, or, due to rotation of the sources, wherein superposition paths at the target shift from convergence point to convergence point around the volume, the pulses may be timed by the system to miss any other source, and, instead, hit neighboring electromagnetic shielding. 
       FIG. 19  is a schematic block diagram of some elements of a control system  1900 , preferably incorporating a machine-readable medium, that may be used to implement various aspects of the present invention, other elements of which are depicted in  FIGS. 1-18 and 20-23 . The generic and other components and aspects described herein are not exhaustive of the many different systems and variations, including a number of possible hardware aspects and machine-readable media that might be used, in accordance with the invention. Rather, the system  1900  is described here to make clear how aspects may be implemented. 
     Among other components, the system  1900  includes an input/output device  1901 , a memory device  1903 , storage media and/or hard disk recorder and/or cloud storage port or connection device  1905 , and a processor or processors  1907 . The processor(s)  1907  is (are) capable of receiving, interpreting, processing and manipulating signals and executing instructions for further processing and for output, pre-output and/or storage in and outside of the system. The processor(s)  1907  may be general or multipurpose, single- or multi-threaded, and may have a single core or several processor cores, including microprocessors. Among other things, the processor is capable of processing signals and instructions for the input/output device  1901 , analog receiver/storage/converter device  1919 , and/or analog in/out device  1921 , to cause a user interface to be provided or modified for use by a user on hardware, such as, but not limited to, physical hand controls (e.g., 3-D hand sensor, scalpel emulator, endoscopic instrument or joystick control) and/or a personal computer monitor or terminal monitor with a mouse and keyboard and presentation and input software (as in a GUI). 
     For example, “window” presentation user interface aspects may present a user with the option to target particular locations of visual emulations of a target model, which lead radiation sources to correspondingly target emulated and modeled real targets, based on live feedback, such as imaging and the detected movement of painted or edge/boundary detected targets within a collateral medium or material. As another example, the user interface and hardware may allow a user to manipulate a “virtual scalpel” in real time, and with reference to a live model depicted on a computer monitor and presenting instantaneous information from an Nuclear Magnetic Resonance Imaging (“MRI”) or X-ray radiographic (e.g., CAT scan) machine, which may allow a surgeon to apply ionizing energy to (or “lance”) particular areas of a target, in particular shapes and sizes or pulses and pulse rates to substantially ionize matter, which size and shape may be given a hardness of edge, tolerance, and strength, all individually controllable by a user or surgeon. A virtual scalpel or other ionizing/Protecting tool may include a shaped cursor which may be semi-transparent, and may allow the user/surgeon to plan and view a portrayed path for the planned future ionization or other, for example actual, robotic, surgical lancing or surgical subject manipulation, before it is actually implemented on a subject (which execution can be done in parts or degrees or completely, with a separate, later command to the system). This surgical or manipulation path planning may be done with a cursor or other display, such as a computer monitor, or depiction/control hardware and techniques (e.g., 3-D physical contour and cutting or manipulation emulation device). In any event, a surgeon may create a path of planned movement for manipulation or lancing by programming such a path and/or by first executing the path in virtual or real space and, optionally, reviewing a depicted path based on that execution, and, if satisfied with the characteristics of the movement(s) of the executed path (e.g., direction(s), length(s), breadth(s), pressure(s), actual or real tissue reaction(s), location(s), size(s) of lancing or projected lancing, or blunt instrument trial of where lancing will take place), all of which characteristics may be displayed numerically or graphically as an attribute of a depicted path in a display as a “Planned Path,” representation, the surgeon may then choose to have the path executed on the patient/target tissues. Optionally, before choosing to execute the path, the surgeon or other user may choose to save a file composed and capable of executing the characteristics of the movement on the system. Also optionally, the surgeon or other user may elect to modify individual, several or all characteristics of the path over any part of the path&#39;s progression, again may choose to save such a file, and again may choose to execute the path, which may be executed at different speeds along the path or even with a graduated acceleration device, which may be stopped at any time during observation of the movement. The system may automatically, or at the surgeon&#39;s direction, adjust the path or path segments for unintended hand tremor by smoothing or drawing more graduated curves and movement accelerations along progressions or as to characteristics of the path. The system may automatically, or a user may direct it, to generate Protective radiation in greater, lesser or other amounts that better interfere and Protect against ionizing radiation, for Protected collateral areas, as well, as another example, based on live feedback concerning the amount of Protection actually occurring through interference, as sensed by the system, and/or based on physical models, including refraction models. The processor  1907  is capable of processing instructions stored in memory devices  1905  and/or  1903  (or ROM or RAM), and may communicate via system buses  1975 . Input/output device  1901  is capable of input/output operations for the system, and may include and communicate through innumerable input and/or output hardware, and innumerable instances thereof, such as a computer mouse, MRI machine, X-Ray radiography device, robotic surgical actuator(s), magnetic field creators or modifiers/oscillators (and magnetically-actuated, locatable nano-particles or manipulation devices that are systemically or locally available in patients, e.g., particles with abrasive surfaces that may spin, expand, grab, cauterize through electric charge, in an oscillating magnetic field and that may also react to markers on targets, available through injection into the patient), such as communications antenna, electromagnetic radiation source(s), keyboard, networked or connected second computer, camera or scanner, a multi-tiered information storage device, such as that described with reference to  FIGS. 8 and 9  (including its actuators and read/write apparati), mixing board, real-to-real tape recorder, external hard disk recorder, additional movie and/or sound editing system or gear, speakers, external filter, amp, preamp, equalizer, computer display screen or touch screen. It is understood that the output of the system may be in any perceptible form. Such a display device or unit and other input/output devices could implement a program or user interface created by machine-readable means, such as software, permitting the system and user to carry out the user settings and input discussed in this application.  1901 ,  1903 ,  1905 ,  1907 ,  1919 ,  1921  and  1923  are connected and able to communicate communications, transmissions and instructions via system bus(ses)  1975 . Storage media and/or hard disk recorder and/or cloud storage port or connection device  1905  is capable of providing mass storage for the system, and may be a computer-readable medium, may be a connected mass storage device (e.g., flash drive or other drive connected to a U.S.B. port or Wi-Fi) may use back-end (with or without middle-ware) or cloud storage over a network (e.g., the internet) as either a memory backup for an internal mass storage device or as a primary memory storage means, or may simply be an internal mass storage device, such as a computer hard drive or optical drive. Generally speaking, the system may be implemented as a client/server arrangement, where features of the invention are performed on a remote server, networked to the client and made a client and server by software on both the client computer and server computer. 
     Input and output devices may deliver their input and receive output by any known means, including, but not limited to, the examples shown as  1917 . The input managed and distributed by the system may be any representational aspect or signal or direct impression captured from any sensed or modeled activity, and may be taken or converted as input through any sensor or carrier means known in the art. In addition, directly carried elements (for example a light stream taken by fiber optics from a view of a scene) may be directly managed, manipulated and distributed in whole or in part to enhance output, and whole ambient light information may be taken by a series of sensors dedicated to angles of detection, or an omnidirectional sensor or series of sensors which record direction as well as the presence of photons sensed and/or recorded, and may exclude the need for lenses (or ignore or re-purpose sensors “out of focal plane” for detecting bokeh information or enhancing resolution as focal lengths and apertures are selected), only later to be analyzed and rendered into focal planes or fields of a user&#39;s choice through the system. For example, a series of metallic sensor plates that resonate with photons propagating in particular directions would also be capable of being recorded with directional information, in addition to other, more ordinary light data recorded by sensors. While this example is illustrative, it is understood that any form of electromagnetism, compression wave or other sensory phenomenon may include such sensory, directional and 3D locational information, which may also be made possible by multiple locations of sensing, preferably, in a similar or measurably related, if not identical, time frame. The system may condition, select all or part of, alter and/or generate composites from all or part of such direct or analog image transmissions, and may combine them with other forms of image data, such as digital image files, if such direct or data encoded sources are used. Specialized sensors for detecting the presence of interference or resonance of radiation of any type, and imaging the sources or capturing the forces applied based on the known characteristics of waves and electromagnetic radiation in particular, may also be included for input/output devices. 
     While the illustrated system example  1900  may be helpful to understand the implementation of aspects of the invention, it is understood that any form of computer system may be used—for example, a simpler computer system containing just a processor for executing instructions from a memory or transmission source. The aspects or features set forth may be implemented with, and in any combination of, digital electronic circuitry, hardware, software, firmware, or in analog or direct (such as light-based or analog electronic or magnetic or direct transmission, without translation and the attendant degradation, of the image medium) circuitry or associational storage and transmission, as occurs in an organic brain of a living animal, any of which may be sided with external detail or aspect enhancing media from external hardware and software, optionally, by networked connection, such as by LAN, WAN or the many connections forming the internet. The system can be embodied in a tangibly-stored computer program, as by a machine-readable medium and propagated signal, for execution by a programmable processor. The method steps of the embodiments of the present invention may be performed by such a programmable processor, executing a program of instructions, operating on input and output, and generating output. A computer program includes instructions for a computer to carry out a particular activity to bring about a particular result, and may be written in any programming language, including compiled and uncompiled and interpreted languages and machine language, and can be deployed in any form, including a complete program, module, component, subroutine, or other suitable routine for a computer program. 
     It should be noted that, in several embodiments of the present invention, it has been stated to be preferable to target leading, outer structures of a target. This serves at least two functions. First, the superposed result will intensify along a path that enters further into the target, rather than exiting the target, at least initially. Second, the Treatment of diseased living tissues may be cut-off from blood supply and metastasis by creating a “dead ring” of encapsulating, ionized tissue. Other patterns, aside from converging and focusing beams and/or waves on the leading structures or volumes of a target may also be used, to otherwise heat, condition and mark the target volume for further identification and actions. For example, patterns which aid in the reabsorption of some targets, such as periodic gaps in heavier dosage designed to “break up” the target mass, may be used. As another example, local regions may be temporarily marked with a pattern of convergent radiation, which may be lower or even a relatively “safe” level, to aid in the proper location of the target for further, ionizing radiation. 
     The embodiments of the present invention may be combined with radio-sensitizing agents, applied to a target volume (e.g., by injection, or drawing by magnetic field and electromagnetic tagging and/or genetic tagging to match a sequence in malignant cells), or naturally coalescing in a target based on other dynamics (e.g., fluid pathways, colligative forces). Agents that fluoresce or otherwise can be read to indicate radiation pathways through both the target volume and collateral material and media, may also be present systemically, to aid the system in assessing existing radiation beam pathways, and adjusting such pathways to optimize dosage in light of reflection, absorption and refraction patterns, as they are observed. Insertable beacons, which may contain lensing and/or radiation re-routing mirrors or other radiation path-diverting elements, may be placed at or near the target, to allow both the accurate location of the target volume and the focusing of radiation from a more diffuse density of radiation in collateral matter or media, into a more concentrated dosage at the target—or may be placed to allow circumnavigation of critical structures, which thereby avoid radiation dosage. More conventional tagging, such as body surface tagging, may also, or alternatively, be used to locate a previously determined target location. The system may plan for, and verify, oscillating or other movements (e.g., breathing, heartbeat, body roll), and how they proceed in comparison to a target, to more accurately locate the target by using a plurality of cross-compared beacons (e.g., by triangulation, quadrangulation, etc., with correction for outlier movements or oscillations of one or more tags). As discussed in greater detail below, a control system such as that discussed with reference to this figure may be used to control any servo motors, instruments and radiotherapy emission sources set forth in this application for controlling radiotherapy techniques, as well as imaging devices, with programming dictating such execution and/or control, by any known wired or wireless communications and command protocols, and carry out or control any aspects set forth in this application. The control system set forth with reference to this figure may also power any such devices or, alternatively, a separate source of power may supply both the devices and the control system. 
     In other aspects of the present invention, a target volume may be accelerated toward a source beam as the pulse enters the target volume, thereby increasing the frequency and energy level in the target, while reversing acceleration as the radiation exits. Using a high frequency vibration of the target volume, relative to its collateral material, and a set of sources delivering radiation at the same time and against the same direction as each vibrational acceleration, it is possible to increase the energy level of absorbed radiation, while decreasing it for collateral material and media. 
       FIG. 20  is a partially cutaway frontal view of a human head  2000 , a radiation source  2001  and an implantable fluorescent focal device  2003 , for use in radiation therapy in accordance with aspects of the present invention. As in other aspects of the present invention, an externally-originating beam of radiation  2005  is provided, and aimed generally toward a target mass  2007 . However, the fluorescent focal device  2003  is placed in between source  2001  and target mass  2007  and external beam  2005  specifically targets a beam-facing, external, absorptive section  2006 , comprising atomic, molecular and/or larger constituent structures capable of absorbing energy from external beam  2005  and, as a result, emitting a different, higher energy or otherwise more tissue-destructive form of radiation, focused toward the target mass  2007 . In other words, focal device  2003  fluoresces in response to receiving source beam  2005  and also serves to focus fluoresced beams of radiation  2008 , concentrating them on the target mass  2007 . Device  2003  may further comprise a radiation-lensing or otherwise radiation-focusing emissive shaped surface  2009 , aiding in achieving that focus for the emitted radiation  2008 . In addition, a variably implantable shield  2011  may be placed on a side opposing fluorescent focal device  2003 , specifically positioned to absorb the fluorescent beams  2008 . In some embodiments, which are preferred, device  2003  creates a limited, controlled-width range of beams, and the beams emit a form of localized or locally absorbed radiation. As a result, the size of both the device  2003  and the shield  2011  may be limited in at least one dimension, greatly reducing their necessary, complementary profile, and greatly decreasing the adverse impact (if any) of their implantation. 
     In some preferred embodiments, external source beam  2005  is of a relatively harmless form of radiation, relative to human tissue (and its genetic material). However, the emitted beams  2008  from fluorescent device  2003  are preferably tissue-ionizing. To achieve this, multi-photon absorption within the structures of device  2003 , and/or magnetic actuation of device  2003  may be used. Alternatively, a less harmful, albeit somewhat ionizing form of radiation, may be used as the external beam of radiation  2005 . In other embodiments, a radiation source may be included within device  2003 , and may be variably shielded by external (including remote control) actuation of a movable shield or interlaceable matrix (not pictured) that may variably withhold the radiation and/or convert it to a harmless form, and, in some embodiments, variably shield that radiation in specified emissive directions (e.g., by variably-pivotable shield louver(s) (also not pictured). 
       FIG. 21  is a perspective view of an exemplary endoscopic radiation focal and shielding instrument  2100 , in accordance with aspects of the present invention. Focal instrument  2100  comprises a main cannula  2101 . Cannula  2101  is insertable into a human or other animal patient&#39;s body with the aid of a rounded, tapered insertion-facilitating tip  2103 , which may penetrate and be inserted through skin, muscular walls, viscera and other organs and layers of tissue—in some embodiments, with the aid of prior incisions through which tip  2103  may then be threaded. Within cannula  2101  is a push-band  2105 , with a high tensile rigidity—in other words, it is relatively inelastic, incompressible and unstretchable along its length, permitting pushing movements to be translated directly into actuation movements of a device attached to its end. However, band  2105  is relatively flexible, and able to turn and curve along its length through channels and around walls within cannula  2101  and instrument  2100  in general. Examples of materials with these properties when in the form of band  2105  include various plastics and natural fibers, such as cellulose, known in the art. Band  2105  splits at the end nearest to tip  2103 , and its split end is attached to distal edges  2106  of a device at the same end of cannula  2101  as tip  2103 —namely, an extending, curving shield, mirror, lens or other curved sheet (or set of sheets)  2107 . When the length of band  2105  is pushed toward tip  2103 , band  2105  is not compressed, but turns in channels  2109  within cannula  2101 , which translate the motion of the ends  2111  attached to edges  2106  into pathways perpendicular to the length of cannula  2101 , and sheet  2107  is extended (as pictured). Due to a natural tendency to curve of sheet  2107 , sheet  2107  takes on a conformation when extended presenting as a concave mirror or other focal lens, or enveloping shield (facing the viewer and upper-left-corner, in the perspective of the figure. Conversely, when band  2105  is retracted, focal sheet  2107  is retracted and folded substantially into the body of cannula  2101  (within storage pockets  2113 ). Sheet  2107  may comprise folding and elastic, force-biased materials that encourage that folding and storage, when band  2105  is so retracted. 
     Driving the pushing or pulling of band  2105  (to cause the extension or retraction, respectively, of sheet  2107 ) are manual controls  2115 , attached to a handgrip  2117 , itself attached to the end of cannula  2101  opposite tip  2103 . In some embodiments, controls  2115  may be electronic, and actuate band retraction and extension via servo/motors wired or otherwise in communication with controls  2115 . However, preferably, at least some of controls  2115  are manual, as pictured, to preserve actuation feel, and attached physical connections, such (such as exemplary push rod  2118  connected to the index and second-finger-actuated manual control loop, at the top) to a lever or wheel (such as exemplary push wheel  2119 , via connector  2121 ), to cause band  2105 , connected to the outer edge of lever or wheel  2119 , to be correspondingly pushed or retracted in channels within cannula  2101 . The lowest control  2115  (which may control another feature of device  2100 , not pictured), by contrast, is pinky and/or ring finger actuated, and cannula  2101  is preferably held between the second and ring fingers, as the user&#39;s hand grips handle  2117 . 
     In a preferred method, a surgeon facilitates radiotherapy or radiosurgery using instrument  2101  by: retracting sheet  2107  (or ensuring that it is retracted) into pockets  2113 ; creating entry incision(s) for a pathway to the far side (opposing the direction from which radiation will be sent) of a radiation treatment target, preferably, at least partially surrounding said treatment target, and focusing radiation onto a treatment target while shielding tissues neighboring the treatment target from radiation when sheet  2107  is later extended; substantially so extending sheet  2107 ; dosing sheet  2107 , the resulting mirror lens it forms, and the treatment target with radiation, while shielding neighboring tissues from the radiation. As will be explained in greater detail below, in some methods of the present invention, the surgeon may also cauterize tissues as he or she is inserting instrument  2100 , or extending sheet  2107 . The steps of the methods discussed above may be carried out in a wide variety of alternative orders, and the listed order is exemplary only. 
     In some embodiments, the leading edges  2106  of sheet  2107  are electrically-powered cauterizing devices, wired to a power source (e.g., through a wire embedded in band  2105 ). In such embodiments, a surgeon using cannula  2101  may cauterize and penetrate tissue blocking the path of sheet  2107  as it is extended, for example, using a cautery-actuating thumb button  2123 , electronically controlling the cauteries. A power source and control system for actuating the cauteries, and other controls, if electronically controlled in the given embodiment, may be resident within instrument  2101  and wired to the actuators they control and power, or may be resident elsewhere but connected to or otherwise able to transmit power and communications to those controls and actuators which they control. 
     Although the example of an instrument administered focal mirror or other lens is shown, it should be understood that this is exemplary, and a separate (or detachable focal mirror may be positioned and or implanted as discussed in reference to this figure. Similarly, a fixed, rather than collapsible mirror or focal lens may be used, in some embodiments. 
     To guide a surgeon using device  2100 , an extension indicator, such as extension degree indicating window  2125  may be included. The rotational degrees surrounding a treatment target that is the focus of mirror or lens  2107  (and therefore, the degree of extension of mirror or lens  2107 ) may then be indicated to the surgeon, as he or she extends it. This indicator may be manually driven, by labels on wheel  2119 , visible through window  2125 . Alternatively, window  2125  may be a control system-actuable and powered (e.g., LCD) display. 
       FIG. 22  is a perspective drawing depicting a new radiotherapy machine  2200  with multiple, simultaneously radiation sources  2201  and  2203 . Each radiation source,  2201  and  2203  may be positioned at a wide variety of radiation emission angles by a computer system-actuable gantry  2205  (comprising a set of adjustable, actuable arms  2206  and  2207 ) to treat a target mass inside a human or other animal subject (not pictured) laying on a flat bed  2208 . Furthermore, sources  2201  and  2203  may be put in motion during such treatment, while remaining trained on the target mass (e.g., at a point  2209 ) preventing the prolonged irradiation of tissues collateral to the treatment target (through which, radiation beams, such as examples  2211 , pass to reach point  2209 ). Gantry  2205  is able to position sources  2201  and  2203  at opposing angles from a line perpendicular to the surface of the human or animal subject (as pictured). In a preferred embodiment, the opposing nature of the positions of sources  2201  and  2203  are maintained, as they are put in motion as discussed above. Also in a preferred embodiment, sources  2201  and  2203  are placed in continuous motion by a rotating rig  2213  to which they are attached, and which is rotated about an axel  2215  by a computer-system controlled motor within a main supporting arm  2217  (which itself may be position adjusted by control system actuable motors). For example, in one exemplary embodiment, rig  2213  rotates about axel  2215  during radiation treatment in a clockwise direction (when viewed from above, as pictured) as illustrated by rotational motion arrow  2219 . In addition, each source  2201  and  2203  may be, simultaneously with this rotational motion, raised to increasingly acute angles with the parallel line from the surface of the subject, by control system actuated servo motors within arms  2206  and  2207 , controlling the angle of hinges  2220 , and linear actuators  2223  controlling the control system-variable length of arm sections  2222 . Correspondingly, emitted beams  2211  from one of the sources (namely,  2201 ) are swept across a spiral path about exemplary spiral pattern  2221  at the outer surface of the human or animal subject. The emitted beams from the other source ( 2203 ) is also swept across a spiral path, preferably different from spiral path pattern  2221 , and, even more preferably, exactly centered within the spaces between spiral path  2221 , as pictured. An example of such an overlapping pattern is shown below, in  FIG. 23 , as exemplary overlapping pattern pair  2301 . To accomplish this, the opposing angle of source  2203  is not an exact mirror image of the angle of source  2201 . But both paths,  2221  and the corresponding path of source  2203 , are constantly trained at the target mass (e.g., at point  2209 ). In an even more preferred embodiment, the spiral paths are adjusted and morphed to optimize the distribution of radiation to the treatment target, and throughout, collateral non-treatment subject tissues. This adjustment can be made in real time, based on live imaging of the treatment target and other subject tissues. 
     In addition to the varying, opposing treatment angles of sources  2201  and  2203 , each source  2201  and  2203  may further comprise multiple beams of radiation  2211 , emitted from opposing angles and intersecting at the treatment target (e.g., point  2209 ) as pictured. Preferably, the position and angle of the multiple beams may also be varied, leading to the ability to select intersection points at different distances from the source  2201  or  2203 . For example, alternate beam positions  2224  and  2225  may be selected and control-system-mandated. By transitioning to such paths, and controlling gantry  2205  to maintain the intersection of the emitted beams at the treatment target (e.g.  2209 ), the dosage to collateral tissues may be even more greatly varied, and spread out across them, while maintaining treatment of the target. 
     In addition, the control system may both rotate main gantry wheel  2227  and body length position adjusting arm  2229  (which the control system may shift fore and aft along bed  2208 ) to distribute the dosage about through wide variety of subject surfaces, anywhere all the way around the subject, and administer the spiral dosages in a smeared out pathway, wrapped and bent around the subject. 
     Due to the differing positions, rotational velocity and movements of sources  2201  and  2203 , and different collateral matter through which radiation generated from the sources must travel, the control system may determine the relative positions of each source from the target, and map all collateral matter, along a function describing the beams&#39; path, and adjust the period, frequency, or any other attribute of beams that they each generate, to carry out constructive superposition at the target throughout treatment in accordance with aspects of the present invention set forth in this application. As with other aspects discussed above, a longer beam path to target, due to a greater distance of a source or greater or more instances of refraction through collateral matter in a beam path, may be determined by the control system, may require advancing the period as the beam is emitted, to optimize constructive interference at the target. The system may seek and exploit paths with greatly differing distances in this way, to decrease incidental constructive interference, and increase protection (by destructive interference) in collateral objects through which the beam paths pass prior to reaching the target. Differences in the birefringence of the collateral material through which the different beams pass may also be determined and applied in planning the period and other wave attributes of each beam upon emission, projecting and causing them to constructively interfere upon arrival at the target site, but not at other, earlier and later, points in time. 
     Radiotherapy machine  2200  may be used with sources implementing other aspects of the invention set forth in this application. For example, beams from source  2201  may be generated that have the same period and frequency, or a harmonic or otherwise constructively-building frequency, when they intersect at the above-stated intersection points. And any beam from source  2201  and source  2203  also may be generated that have the same period and frequency, or a harmonic or otherwise constructively-building frequency, when they intersect at the above-stated intersection points. 
     But machine  2200  may also be used with more conventional radiation therapy sources and techniques, not involving the intersection of beams at a target, with their separation within collateral tissues. In another embodiment, one source  2201  does not simultaneously treat the same point as source  2203 , and their respective beams need not intersect with one another. Instead, a source first treating the target point charges the materials with its radiation beams (some of which are absorbed within atoms of the target mass, e.g., exciting electrons within DNA to higher-energy orbitals. While still charged, the second source then treats the same point, leading to additional energy absorption, breaking of bonds, and greater destruction of the target mass. In this way, dosage to collateral matter can be even more greatly distributed. 
       FIG. 23  depicts a series of radiation beam pattern pairs,  2301 ,  2303  and  2305 , emanating from sources  2201  and  2203 , discussed above. It is to be understood that, as with pattern  2221 , discussed above, these patterns occur at or about the surface of the human or animal subject (pair  2301  and  2303 ) or within the subject&#39;s body, but not as far down as the target point (pair  2305 ). First, in pair  2301 , as discussed above, a pattern from source  2201  at or about the surface of the subject is pictured (also pictured in the greater context of a radiotherapy machine in  FIG. 22 , above, as spiral pattern  2221 .) A second spiral,  2302 , is also pictured, spaces between pattern path  2221 . As both patterns descend and converge toward a target, however, they merge and, due to overlapping constructively interfering frequencies, periods, polarity or other attributes, form a united waveform of much higher energy density at the treatment target. In an embodiment creating pattern pair  2301 , each source preferably has an angle relative to a line perpendicular from the subject&#39;s outer surface permitting the nesting of spiral  2302  within the interstitial space of pattern  2221  until each pattern reaches the treatment target. 
     Beam pattern pair  2303  illustrates additional features, comprising destructive interference at a point in time prior to beams from the two sources converging. The top pattern,  2307 , describes a pattern above the subject drawn by source  2201 , which is positioned at an angle more acute to the perpendicular line from the surface of the subject than source  2203 . The lower pattern,  2309 , is drawn by source  2203 , out wider from the subject than source  2201 , at the surface of the subject. Due to its more oblique treatment angle, pattern  2309  is wider and descends more slowly than pattern  2307 . But pattern  2309  also converges at a greater rate than pattern  2307 . Thus, at the instant pictured, the outer edge sweep  2311  of pattern  2307  may abut an inner sweep  2313  of pattern  2309 . If those abutting regions are made, by a control system planning the period, frequency, polarity and other radiation wave attributes of each pattern, to destructively interfere at the instant shown, protection will then occur at the instant pictured. At a later interval within a treatment target, however, due to the greater rate of convergence and slower rate of descent of pattern  2309 , the two patterns (then depicted as  2315  and  2317 ) are then overlapping at constructively related regions, as they converge—again by a control system planning the period, frequency, polarity and other radiation wave attributes of each pattern, causing outer region  2318  to constructively interfere with region  2319 . 
     The control systems discussed in  FIGS. 21-23  may be a computer system such as that set forth earlier in this application, with reference to  FIG. 19 . 
       FIG. 24  is a perspective drawing, depicting aspects of the invention applied in a handheld wireless communications device  2400 . As with the instrument and method set forth above, in reference to  FIG. 21 , device  2400  comprises at least one extendable and retractable sheet  2401 , which forms a concave mirror or other focal lens, or enveloping shield when extended (as pictured). Also as with the sheets described in reference to  FIG. 21 , and by the same encompassed features, sheet  2401  envelopes more greatly, and becomes more concave, the more it is extended from a stowage bay  2402  comprised in an actuator—in this instance, shielding and focusing actuator  2403  (in which sheet  2401  may be furled, for example, around a rotary motor to which it is attached). However, unlike the embodiment set forth in  FIG. 21 , in this instance, sheet  2401  does not extend to cover a treatment target. Instead, sheet  2401  is sized and curved to envelope a wireless communications broadcasting sub-device  2405 , when sheet  2401  is extended from bay  2402 . As pictured, broadcasting device  2405  is comprised in communications device  2400 . Communications device  2400  may be any portable communications device that may be held in close proximity to a human or other animal. For example, communications device  2400  may be a smartphone, personal digital assistant, tablet, or other personal computer. Broadcasting device  2405  may be a WIFI or other antenna, other wireless communications gear or any device emitting any form of radiation, or potentially emitting any form of radiation. The broad side  2406  of communications device  2400  that faces the viewer of the figure is the side of communications device  2400  that faces a user of the device, during normal usage. A screen or other GUI, along with a mounting bracket, may be overlaid onto side  2406 , when the complete device is assembled. 
     Thus, when sheet  2401  is extended from bay  2402 , enveloping the side of broadcasting device  2405  that faces a user of device  2400 , it serves to: (1) focus ambient electromagnetic radiation received from the other side (facing into the page) of device  2400  onto broadcasting sub-device  2405 ; (2) reflect outbound electromagnetic radiation toward another device(s) with which device  2400  is communicating, and (3) shield the user from electromagnetic radiation from device  2400  and other sources. Depending on the degree of extension, sheet  2401  will undertake more curved (when fully extended) and more flat (when closer to fully retracted) shapes. Thus, a control system in communication with and controlling sheet  2401  and actuator  2403 —such as control system  2407 —can select from a variety of altered outbound and incoming angles of shielding and reflection, to better focus, receive and send electromagnetic signals from sub-device  2405 , and actuate actuator  2403  to create those angles of shielding and reflection, depending on conditions sensed by the control system. 
     For example, if ambient radiation sensed by device  2400  is of a sufficient strength, reception of electromagnetic radiation from all sides of broadcasting sub-device  2405  may not be required to establish an adequate local network connection for device  2400  and, as such, the control system may fully extend sheet  2401 , to maximally protect a user on the user&#39;s side of device  2400 . If, however, the signal later decreases in strength, or a wireless connection is otherwise lost, decreased in quality or moves, the control system can command actuator  2403  to retract, completely or to varying degrees, to select angles of reflection and focus that maximize reception of the electromagnetic signals. 
     Control system  2407  may be any suitable control system, such as the control system set forth in reference to  FIG. 19 , above, and may communicate with and/or partially reside on remotely connected hardware. Sheet  2401  may comprise of or be lined with a fine mesh or other layer of copper or any other materials known in the art to shield electromagnetic radiation. Sheet  2401  may also be lined with a layer of any electromagnetic reflective material known in the art. While such details have been eliminated for clarity of visual presentation, it should be understood that any part of communications device  2400  may be connected to any other part of communications device  2400 , for example, by wired or wireless interconnections. Similarly, any part of communications device  2400  may be physically connected to any other part by any connecting devices known in the art (e.g., solder, screws, and intermediate brackets, such as bracket  2409 , shown mounting control system  2407  and broadcasting sub-device  2405 , and connecting them to outer housing section  2411 ).
