     FIELD OF THE DISCLOSURE 
     The present disclosure is related to the reduction and/or the removal of moisture from material or plants using the delivery of microwave radiation combined with radio frequency (RF) energy, using an apparatus that includes a vertical feed conveyer particularly, for the removal/reduction of moisture content level associated with cellulose-based materials, such as sawn or dimensional wood, lumber, plant(s), leave(s), and/or flower(s); fresh materials; fibrous materials; or porous materials, such as ceramic; or other specimen(s) or material(s). 
     BACKGROUND 
     In the process of manufacturing fibrous materials, particularly, cellulose-based materials, (such as for example, wood, plant(s), flower(s), leave(s), paper, textile, a specimen (for example, plant/flower species, piece of a mineral, etc., used as an example of its species or type for scientific study or display), and/or other materials), moisture and/or oil must be removed to a desired moisture content level, while maintaining a uniform moisture profile. Failure to do so can result in inferior and defective product. For example, in the process of drying green wood, for example, typically using a kiln, free water from cell lumina will naturally be depleted first, while the bound water (bound to the wood via hydrogen bonds) saturating the cell walls will remain until all of the free water is removed. The moisture content remaining in the cell walls after the free water has been removed is referred to as the Fiber Saturation Point (FSP), and is typically between around 24 to 32% and could reach levels of approximately 70%. The FSP further defines the moisture content below which, as the material, for example, wood is further dried, properties such as volume and strength are affected. As is the case in typical kiln drying, the outer surfaces will dry and consequently shrink faster than the interior portions of the material, for example, wood, plant(s) or flower(s). As a consequence of this relative shrinkage, the wood, for example, can crack and split (a defect generally referred to as “checking”). In addition, if the faster drying portions become too dry at any point during the process, the strength of the material can be altered and warping of the example material, wood can occur. 
     In order to mitigate these problems, conventional kiln drying processes include alternately heating and drying the material, for example, wood with a moisture-removal mechanism, such as by circulating unsaturated air to remove the moisture as it evaporates off, and rewetting the example material, wood to redistribute the moisture in order to restore a more uniform moisture profile throughout the bulk of the material. For the heating process, various conduction, convection, and radiation heating methods have been used, including electrical heating means, steam-heated heat exchangers, and solar energy. In this so-called charging phase of a conventional kiln, as the temperature rises in the kiln, the material, for example, wood, plant(s), leaves, flower(s), fresh material(s), other material(s) and/or specimen surface is typically “over-dried” so that the moisture content of faster drying portions is less than that of the desired final product. During the discharge or rewetting phase, the relative humidity in the kiln rises as the temperature falls. This slows the surface drying rate and equalizes the moisture profile through the material, for example, the wood, plant(s), leaves, flower(s), fresh material(s), other material(s) and/or specimen(s). Air is also constantly circulating through the kiln and around the material, for example, wood, plant(s), leaves, flower(s), fresh material(s), other material(s) and/or specimen(s) to remove moisture and assist in drying the wood, plant(s), flower(s), leaves, specimen(s), or other material. The rewetting and drying are typically further controlled by regulating the temperature and humidity of the air circulating in the kiln. 
     There are many disadvantages using such conventional kilns including possible loss of the strength of the example material, wood due to over-drying of the outer surfaces, the possibility of other defects in the wood due to the difficulty in maintaining a uniform moisture profile, high energy consumption, and the release of pollutants into the atmosphere. In addition, the long drying times and relatively small amount of the example material, wood that can be processed in each batch cause a bottleneck in the entire production process. 
     Other known traditional methods of drying hardwood timbers can take several months requiring controlled conditions to prevent damage to the timbers. Such known drying processes are controlled so that the loss of moisture is gradual and the timber or wood shrinks evenly. These processes can take as long as 60 days. 
     Therefore, in order to overcome some of the disadvantages of conventional methods of drying hardwood and other methods of kiln drying, early attempts were made to use microwave radiation to try to remove moisture from wood. However, such early attempts failed due to collection of moisture in the microwave emitter, causing it to malfunction, and further, due to the collection of moisture on the surface of the material, thereby preventing further removal of moisture from within the bulk of the material. 
     A method of using microwave to pretreat wood prior to applying conventional kiln drying techniques is disclosed in U.S. Pat. No. 7,089,685 to Torgovnikov, et al. (referred to hereinafter as the &#39;685 patent). The &#39;685 patent discloses subjecting a surface of wood to microwave at 0.1 to 24 GHz to provide a modified wood zone on the exterior having increased permeability relative to the untreated core volume of the wood. The &#39;685 patent discloses that this microwave pretreatment reduces the time required for the subsequent drying process using a conventional kiln. A variation of the kiln drying process uses RF in vacuum (“RF/V”) to heat a stack of wood volumetrically, causing a more uniform moisture profile in the heating process, and causing the kiln environment to become superheated. The wood is heated under vacuum to create a pressure gradient, the pressure decreasing toward the surface, to draw the moisture toward the outer surfaces. The moisture quickly converts to water vapor at the reduced pressure and can be condensed or drawn out of the kiln by a vacuum pump as steam during the discharge and moisture removal phase. The humidity and temperature are controlled to allow a certain amount of moisture to remain on the surface of the wood to avoid overdrying and to ensure a uniform moisture profile to relieve internal and external stress in the wood throughout the process. While such RF/V systems speed up the wood drying process, they have a high operating cost due to the energy requirements of generating the RF and vacuum pumps. In addition, like the other kiln systems, RF/V is a batch process which is limited in the capacity of wood that can be processed at one time. Accordingly, a need still exists for a system and method of removing moisture from fibrous materials such as sawn and dimensional wood. It is especially desirable for the system and method to operate at a reduced energy and manufacturing cost and in a continuous mode rather than in a batch process. 
     It is even further desirable for a more effective system and method that reduces prolonged drying times associated with conventional kiln and RF Vacuum batch kiln processes. It is even further desirable for the system and method to offer additional commercial and environmental benefits including the prospect of new products that extend our existing timber or other fresh material resources and reduce any unnecessary damage to timber and other fresh material resources that require any such drying treatment in accordance with the disclosed system and method. It is even further desirable for the system and method to permit and accelerate processing of sawn, dimensional wood, timber, and/or other fresh materials such as preservative treatments for generating environmentally friendly end-product(s). 
     SUMMARY 
     The present disclosure provides a system and method of removing and/or reducing moisture effectively from fibrous materials, particularly, from sawn and dimensional wood, lumber, flower(s), leaves, plant(s), fresh materials, specimen(s) or other materials such as ceramic, using microwave radiation. In addition, the present disclosure is applicable to removing and/or reducing moisture that includes water and/or oil moisture from fresh materials, porous materials and/or other materials structurally known to bind, bound and/or absorb moisture. 
     In contrast to the batch systems of the prior art, the system and method of the present disclosure advantageously provide a continuous process for removal of moisture from fibrous materials such as sawn and/or dimensional lumber, flower(s), plant(s), leaves, specimen, or other material. The process preferably includes translating the fibrous material, for example, lumber, flower(s), plant(s), leave(s), specimen, or other material on a conveyor belt through an enclosure in which the heating and drying of the lumber, flower(s), leaves, or plant(s) is conducted. The method includes alternatingly applying a heating phase to a portion of the lumber, flower(s), leaves, plant(s), or other material, followed by a drying (cooling) phase for the removal of moisture until the lumber reaches a desired final moisture content. The heating phase is provided by irradiating the portion of the lumber, flower(s), leaves, plant(s), or other material with microwave for a period of time and with sufficient intensity to heat and vaporize moisture preferably throughout the entire thickness of the lumber without significant destruction to the ray cell tissue of the wood, flower(s), leaves, or plant(s). Preferably, air is constantly circulated through the enclosure using ventilation and exhaust fans during the heating process. In addition, drying or cooling phases can also be provided in the absence of microwave or other heating for a period of time determined by at least one of a number of constantly monitored parameters, such as change in the overall moisture and/or oil content of the wood, lumber, flower(s), leaves, or plant(s), or in the uniformity of a moisture and/or oil profile within the wood, lumber, flower(s), leaves, or the plant(s). In this way, the heating and drying schedules of conventional kilns are essentially performed in a continuous process, rather than a batch process, and at a significantly faster rate. 
     In one aspect, the portion of the material, for example wood, lumber, flower(s), leaves, plant(s), or other material that is irradiated by microwave corresponds to a length thereof of the wood, lumber, flower(s), leaves, plant(s), or other material that is contained within the enclosure. Accordingly, microwave is applied along the entire length and width of lumber, wood, flower(s), leaves, plant(s), or other material within the enclosure for a first period of time to provide the heating phase, and is accompanied by or associated with any appropriate method for a second period of time to provide the drying and cooling phase. Preferably, ventilation and exhaust fans are continuously used to circulate air through the enclosure to remove moisture from the surface of the lumber, wood, flower(s), leaves, plant(s), or other material, and from the enclosure, particularly during the drying phase. 
     In another aspect, the alternating periods of microwave heating and drying, preferably using circulating air, are provided by translating the material, for example, lumber, on a conveyor belt through an enclosure that provides a number of rectangular swaths of electro-magnetic radiation, including RF and/or microwave, for heating a portion of the lumber, wood, flower(s), plant(s), leaves, or other material. Each rectangular swath extends across a width of the conveyor belt, transverse to the direction of translation of the conveyor belt. The rectangular swaths are separated by a fixed distance. Accordingly, the enclosure contains alternating rectangular swaths of microwave radiation for providing heating phases, separated by rectangular drying regions that are not irradiated by microwave for alternating the heating phases with drying phases. The periods of time corresponding to the heating and drying phases are controlled by the speed of the conveyor belt, the length of the rectangular swaths in the direction of the conveyor belt, and the separations between the rectangular swaths. 
     In various aspects, the method can also include alternating the application of microwave radiation with the application of longer wavelength RF within a microwave heating phase, or following a microwave heating phase. For example, the rectangular swaths of microwave irradiated sections of the enclosure can be staggered between pairs of opposing electrodes along the conveyor belt for the application of RF to the portion of lumber as it translates along the conveyor belt. One or both of the applications of RF and microwave heating can be periodically accompanied or combined for a period of time with a drying phase. Air is circulated over the portion of the lumber, wood, flower(s), plant(s), leaves, or other material at least during the drying cycle to remove the moisture evacuated therefrom. 
     Optionally, the microwave heating can be accompanied by RF during a heating phase for predetermined periods of time. Alternatively, the microwave heating can be interrupted by RF pulses during a heating phase for predetermined periods of time. 
     In one aspect, a method for removing moisture from a fibrous material includes irradiating a portion of the fibrous material with microwave to heat and vaporize moisture within the fibrous material during a heating cycle; and accompanying or combined with the delivery of microwave with RF heating for a period of time during the heating cycle in order to equalize and draw the moisture within the fibrous material to outer surfaces of the fibrous material. 
     The method preferably further includes circulating air over the portion of the fibrous material to remove the moisture evacuated therefrom. 
     In certain aspects or embodiments, disclosed is a system for reducing a moisture content level of a material or plant. Such system comprises an enclosure for heating and drying the material or plant enclosed therein; a vertical track mechanism for situating the material or plant vertically; and a microwave delivery device positioned interior to or adjacent to the enclosure, the device delivering microwave radiation to heat and vaporize moisture of the material or plant over a pre-determined period of time of a heating cycle; a radio-frequency emitter positioned interior to or adjacent to the enclosure. The emitter is configured to volumetrically heat at least a portion of the material or plant, wherein emitted radio-frequency (RF) energy is combinable with the microwave radiation to reduce a moisture content level of the material. The disclosed system further comprises a power supply operatively connected to the radio-frequency emitter, the power supply being configured to energize the radio-frequency emitter for a time interval within the heating cycle.

     In certain aspects or embodiments, the system further comprises a circulating air device, the circulating air device circulating unsaturated air around the material or plant and out of the enclosure to remove the moisture evacuated from the fibrous material during the heating cycle. The material or plant may further comprise one or more of sawn lumber, multiple plants, flower(s), leaves, a specimen, and ceramic. In certain aspects or embodiments, the system may further comprise that one or more of the following processes occur during the heating cycle: photosynthesis of the plant occurs during delivery of the microwave radiation; and biosynthesis of the plant occurs during delivery of the RF energy.

     DETAILED DESCRIPTION 
     The following sections describe exemplary embodiments of the present disclosure. It should be apparent to those skilled in the art that the described embodiments of the present disclosure provided herein are illustrative only and not limiting, having been presented by way of example only. All features disclosed in this description may be replaced by alternative features serving the same or similar purpose, unless expressly stated otherwise. Therefore, numerous other embodiments of the modifications thereof are contemplated as falling within the scope of the present disclosure as defined herein and equivalents thereto. 
     Throughout the description, where items are described as having, including, or comprising one or more specific components, or where processes and methods are described as having, including, or comprising one or more specific steps, it is contemplated that, additionally, there are items of the present disclosure that consist essentially of, or consist of, the one or more recited components, and that there are processes and methods according to the present disclosure that consist essentially of, or consist of, the one or more recited processing steps. 
     It should be understood that the order of steps or order for performing certain actions is immaterial, as long as the embodiment remains operable. Moreover, two or more steps or actions may be conducted simultaneously. 
     Scale-up and/or scale-down of systems, processes, units, and/or methods disclosed herein may be performed by those of skill in the relevant art. Processes described herein are configured for batch operation, continuous operation, or semi-continuous operation. 
     Referring to  FIG. 1 , an embodiment of a system  10  of the present disclosure includes a conveyor belt  12  and an enclosure  14 , which forms a tunnel through which the conveyor belt  12  translates. Moisture is removed from fibrous materials that are loaded onto the conveyor belt  12  as they translate through the enclosure  14 . Waveguide channels may be affixed to the enclosure  14  for delivery of microwave energy at manifolds ( 26 ). Referring also to  FIG. 2 , the enclosure  14  also includes interior surfaces and structures for mounting the various components necessary for heating, drying, and monitoring the materials as they pass through the enclosure  14 . 
     In contrast to the batch systems of the prior art, the system and method of the present disclosure advantageously provide a continuous process for removal of moisture. In an exemplary embodiment shown and described herein, moisture is removed from sawn or dimensional lumber using a representative number of alternating elements or stages that allow alternately heating and drying sections of the lumber as it translates through the enclosure  14 . It is understood, however, that the system and method can be adopted for any type of suitable material requiring the removal of moisture. It is also understood that the number, spacing, and configuration of the various elements for heating and drying can be adjusted as necessary to heat and dry the material in a continuous process. 
     An additional advantage of the system and method of the present technology permits the removal of moisture from sawn and dimensional wood, flower(s), plant(s), leaves, or other porous or fibrous materials, so the resultant treated materials, plant(s), flower(s), leaves, wood or timber has increased permeability. This increased permeability in effects permits the infusion of environmentally friendly resins that can be infused through such microwave treated wood to improve the process for preservative treatments thereto thereby reducing costs and improving the wood&#39;s or porous material&#39;s appearance, strength, stability and durability. 
     In certain aspects or embodiments, the disclosed drying system and method can be used to dry moisture and/or extract hemp oil from hemp leaves, flower(s) and/or plant(s). In certain embodiments, the input moisture level is 80-85%, and the output moisture is 8-10%. The disclosed system is implemented in order to dry hemp correctly and efficiently, resulting in a product ready for hemp oil extraction or other industrial or medical purposes. Hence, another benefit of the disclosed system and method is that it can be implemented to dry hemp plant(s)/leaves/flowers more efficiently and thoroughly, reducing overhead costs and allowing growers to process their product faster. The disclosed system and method can be used dry the flowers quickly, to meet the requirements of a variety of flowers drying. The flower patterns and/or color can be artificially controlled during the drying processing, in order to preserve the nutrients and color of the dried flower to the utmost, as required by the industry. In certain embodiments, the disclosed system and method can be implemented in small, portable systems designed for cannabis production, for example, and span to larger, industrial-sized systems for processing multiple tons of hemp biomass per day. 
     The disclosed system and method in certain aspects or embodiments can implement a shorter drying cycle, with large output capacity, and can achieve large quantities of continuous drying. The drying cycle is enclosed in the dryer apparatus, with high thermal efficiency and energy saving. In certain embodiments, the automatic cycle can achieve a multiple flip, uniform drying effect. The disclosed system and method can achieve high evaporation efficiency, with the best quality and color of dried flowers. 
     In certain aspects or embodiments, the disclosed system and method can be used for drying and/or lowering the moisture content level of for example, herbaceous plants. The temperature of the equipment is controllable, which is sufficient to improve the quality of the finished product. The disclosed system and method can be widely used for example, in food, beverage, medicine, daily chemical, brewing, cosmetics and other industries. In certain aspects or embodiments, a feeding conveyor feeds the fresh material or other material through the dryer through the conveyor for drying. A discharge conveyor may be implemented to transport dried materials. A drying host may be used to load the material into drying host mesh belt and move forward from top layer to bottom layer (or vice versa) in accordance with one or more embodiments of the disclosed system and method as described hereinbelow. In certain aspects or embodiments, the disclosed system may include application of Radio Frequency (RF) energy and/or microwave (MW) energy, and/or fans that provide sufficient air volume to the dryer, not only based on the level of heat required to dry, but also taking enough air volume to improve the drying efficiency. In certain embodiments, a heat exchange furnace is used to provide heat for the drying machine, the cold air and hot air exchange, and finally at the suitable drying temperature enters into the dryer absorb by fan. A control panel may be implemented along with moisture sensors to control speed and temperature. The moisture sensors can sense the water or moisture content level and/or the oil content of plant(s), flower(s), leave(s), or other material. 
     In certain aspects or embodiments, the plant(s), flower(s), leave(s), specimen(s), fresh materials and/or other material is transported by the feeding conveyor to the inside of the dryer. The material passes from the first layer to the last layer via the conveyor belt, and the dried material is conveyed by the discharge conveyor. The disclosed system and method may use hot air as the drying medium. In such aspect or embodiment, the hot air passes through the material from the bottom to top (or vice versa in other embodiments). Depending on the drying configuration of the system, the final moisture content can be delivered out of the top or bottom of the dryer apparatus. In certain aspects or embodiments, the drying apparatus not only relies on heat to dry, but also implements microwave and/or RF energy and described in greater detail hereinbelow. Hence, the disclosed system and method can improve/increase the drying efficiency and reduce the drying time. 
     Yet, another advantage of the present system and method is the application to the hemp drying industry. Hemp drying system designed to utilize the combination of heat (for example, by alternating RF and microwave energy as described in greater detail hereinbelow) and/or circulating air to rapidly dry hemp leaves and flowers. Low temperature drying may also be implemented as the temperature and/or applied energy is adjustable dependent on the moisture level of the hemp leaves or flowers and/or the required level that would render it useful to a particular industry once the desired moisture content level is achieved. For example, certain applications are the extraction of CBD oil present in hemp leaves. Such CBD oil is currently in greater demand in the industry as exhibiting potential high and useful medical value. CBD oil is made by extracting CBD from the cannabis plant, then diluting it with a carrier oil like coconut or hemp seed oil. Such CBD oil is gaining momentum in the health and wellness world, with some scientific studies confirming it may ease symptoms of ailments like chronic pain and anxiety, among other potential health benefits and/or medical related uses. For example, CBD oil may help reduce symptoms related to cancer and side effects related to cancer treatment, like nausea, vomiting and pain. 
     Some test-tube and animal studies have even shown that CBD may have anti-cancer properties. For example, one test-tube study found that concentrated CBD induced cell death in human breast cancer cells. Other studies have shown that CBD inhibited the spread of aggressive breast cancer cells in mice. However, these studies are generally test-tube and animal studies, so they can only suggest what may be effective in people. More studies in humans are needed before more solid conclusions can be made. CBD may have beneficial effects on acne due to its anti-inflammatory qualities and its ability to control the overproduction of sebum from the sebaceous glands. Despite the requirement for more research, nonetheless, the interest and demand has risen in connection with such studies and indicated uses of CBD in compliance with pertinent laws, etc. Numerous other health benefits have been suggested with use of CBD including with diabetes, substance abuse, mental disorders and certain types of cancers. Though CBD has been shown to help reduce symptoms related to cancer and cancer treatment, and may even have cancer-fighting properties, more research and scientific evaluation is needed to assess its efficacy and safety. 
     In connection with the risen demand for CBD, in accordance with certain aspects or embodiments, the disclosed system and method can accomplish drying hemp leaves/flowers/plants with targeted precision. Hence, such drying is accomplished more effectively and efficiently, resulting in a product with reduced moisture content that is ready for industrial uses, for example, hemp oil extraction or other industrial and/or medical purposes. In certain applications, embodiments of the disclosed system and method permit smashing some fresh hemp plants before drying, by incorporating added peripherals to the system such as a hemp shredder. 
     Additional system configuration designs permit tailoring the drying cycles based on the type of particular fresh material being dried. For example, different system configurations can be implemented to include the capacity to dry various fruits and/or vegetables. Certain system embodiments can be further tailored to deliver industry, biological products and extracts, Chinese herbal medicines, other herbal or homeopathic type supplements, health care products, industrial materials and/or other industry-type products that may require an additional drying cycle and/or additional drying cycle of vacuum freeze-drying. In certain aspects or embodiments, vacuum freeze-drying peripheral and/or main enclosure drying equipment is implemented that is suitable for the food industry, biological products and extracts, Chinese herbal medicines, homeopathic type supplements, health care products, and/or other industrial materials. In certain aspects or embodiments, vacuum freeze-drying equipment is implemented with the fresh material being pre-cooled in low temperature condition, under the condition of vacuum low temperature, then heating the fresh material. The fresh material is rendered in frozen form via tiny ice grain sublimation, directly collected by the condenser, resulting in dried materials. A streamlined de-watering and/or de-moistening method is implemented in such embodiments. 
     In yet additional embodiments, continuous multi-layer seeds drying is implemented in accordance with the disclosed system and method. The system can be implemented for continuous drying of materials. Advantages such as fast drying speed, high evaporation intensity and improved product quality can be achieved. In an example implementation, the system can be used for mass drying of flake, strip and granular materials with improved and/or good air permeability being achieved. Example of such materials include sunflower seeds, pumpkin seeds, watermelon seeds, melon seeds, nuts, etc. 
     In accordance with yet further system embodiments, configurations of the disclosed system can use microwave drying cycle to perform grain microwave drying and achieve curing of such grains. Such example embodiments can used for grain drying, puffing, baking products, sterilization and other processing, such as: black beans, soybean, barley, oats, buckwheat, mung bean, red bean, cowpea bean and other type grains or beans. 
     Yet, another advantage of the present system and method is the sterilizing effects of the delivery of microwave irradiation to the materials being dried. Fungi, bacteria and other etiological agents are destroyed using the disclosed technology system and method. 
     Preferably, various parameters are continuously monitored throughout the entire wood, plant, flower (i.e., hemp flower, hemp leaf or hemp plant), specimen, or other material drying process and used to tune operating parameters in real-time and to achieve a desired level or profile of moisture remaining in the final product. For example, levels and/or changes in an overall moisture content of the lumber, flower (i.e., hemp flower), leaves or plant, as well as the moisture profile (and/or oil content) of the lumber or plant(s) are preferably continuously monitored and used to determine system operating parameters. Such system operating parameters include, but are not limited to, the power, intensity, operating frequency, orientation of the electric field strength vector and other operating parameters of the microwave source (and RF, in certain embodiments) of heating, the humidity and temperature of the circulating air used in the drying process, the period of time needed for each heating phase and drying phase, and speed of the conveyor belt. 
     Generally, the disclosed technology is described as a two-step process which treats the zones of the exterior shell of the wood (or other materials) and treats the core volume of for example, the wood, plants, flowers, leaves, specimens, fresh materials, or other materials such as porous or fibrous materials undergoing the drying system and method either simultaneously or in sequence. The electric field vector (E) is generally oriented parallel to the surface of the wood grains for irradiating the exterior shell zones. The electric field vector is also generally oriented perpendicular to the wood grains for irradiation of the core volume. Any additional treatment is implemented and configurable based on the thickness and size of the wood, flower(s), plant(s), leaves, fresh materials, or other materials that are being treated. In addition, certain portions of the wood, flower(s), plant(s), leaves, fresh materials, or other materials do not require treatment so the system is intelligently adaptive and receptive to the current moisture levels and other conditions of the wood, plant(s), leaves, flower(s), specimen, fresh material(s) or other material, while the material or specimen is being treated and is described in connection with the embodiment shown in  FIG. 6  as described in greater detail below. For example, it may be suitable to treat core regions of the lumber, wood, plant(s), leaves, flower(s), specimen, fresh material(s) or other material. Alternatively, it is otherwise desirable to allow an exposed surface to remain untreated. Depending on the application of the wood, plant(s), leaves, flower(s), specimen, fresh materials(s) or other material in the pertinent industry, it may be suitable to treat the materials, etc. accordingly. 
     Another property of the wood for example, to consider, is that wood cells generally do have a maximum absorption of microwave energy if the E field vector is oriented parallel to the length of the cell. When the E vector is oriented perpendicular to the main wood tissues, the ray cells heat faster than the other tissues of the wood and absorb more energy without destruction to the main wood tissues. Wood ray cells are generally in the radial direction, perpendicular to the main wood tissues so these ray cells will generally have a maximum level of microwave energy absorption when the E vector is oriented in the radial direction. Therefore, when the orientation of the E-field vector is modified from perpendicular to the wood surface to parallel to the surface wood, the absorption of the wood increases. Therefore, the system and method of the disclosed technology in certain embodiments can control the directional component of the E-field when applying microwave energy between the preferable perpendicular direction to the wood surface and parallel direction to the wood surface, depending on the desired results. 
     It is appreciated in the art that the moisture content of wood (MC) is expressed as the weight of water present in the wood divided by the weight of dry wood-substance. For example, a 30 lb. board with 10 lb. of water and 20 lb. of dry wood-substance has a MC of 50%. MC of wood may even be great than 100% because the weight of water in the wood can be greater than the weight of the dry wood-substance. Freshly cut wood may have a MC as low as 30% to as high as 250%. When wood is dried, it should be dried at specified rates to prevent degradation of the wood including of its core region. Therefore, efficient drying processes that effectively target the regions of the wood at the proper heating settings, are desirable to reduce unnecessary waste of environmental resources such as timber. 
     As shown in  FIG. 3 , in one embodiment, an example material, dimensional lumber  16  is loaded onto the conveyor belt  12  (from the right of the figure shown) for translating (to the left in the figures) through the enclosure  14 . As the lumber  16  translates through the enclosure  14 , it is preferably heated evenly by microwave radiation  30  delivered by nozzles  18  positioned on either side of the conveyor belt  12 . In certain embodiments, the nozzles  18  may be configured as jet nozzles positioned in space between adjacent waveguide sections. The nozzles  18  may also be positioned along opposing waveguide sections. In other embodiments nozzles  18  may rotate in a sweeping motion along the length and across the width of the dimensional lumber  16  as it translates along the conveyor belt, preferably uniformly irradiating and heating the lumber as it passes through the enclosure  14 . Assuming a nozzle is positioned at 0 degrees when it is perpendicular to the conveyor belt, each nozzle preferably has a range of motion of at least +/−45 degrees along the length of the enclosure  14 , or up to almost +/−90 degrees for a full 180 degrees range of motion. 
     The conveyor belt  12  can be formed of any suitable material, such as a plastic that is inert to microwave radiation. 
     The microwave radiation  30 , which penetrates and heats the lumber, can be generated by any suitable source of microwave and is preferably directed to the nozzles  18  through appropriately sized and shaped channel waveguides  20  running lengthwise along the enclosure. It should be noted that though only one layer of dimensional wood  16  is shown on the conveyor belt in the figures, it is contemplated that several layers can be stacked, with or without spacers, for treatment at one time, with the appropriate placement of additional microwave emitters. Accordingly, as shown particularly in  FIG. 3 , the nozzles  18  can be positioned along both an upper waveguide channel  22  which may transition to known mediums such as cable or coaxial mediums, and directed downward for heating the dimensional lumber  16  and also along a lower waveguide channel (not seen in the figure) and directed both horizontally and downward as in the figure shown, or also upward for radiating through a stack of the dimensional lumber  16 . Additional waveguide channels and nozzles can be appropriately placed at various levels for uniformly heating several layers. 
     Additionally, jet nozzles are included in certain embodiments to deliver levels of air streams to the material as determined by the respective nozzle&#39;s head, the shape of the nozzle and the size of the mouth of the nozzle. These jet nozzles may be included in certain embodiments to supplement the delivery of microwave energy to the material being dried by sweeping moisture away from the surface by delivery of bursts of air streams. The jet nozzles may deliver air streams and furthermore, be configured to deliver high velocity gas streams formed from gases at surface moisture removal points of the drying process. These nozzles are configurable to target a certain level of moisture from the surface of the material undergoing the disclosed drying process. 
     In the embodiments shown in the  FIGS. 2-5 , three sets of nozzles  18 , which may be configured to be rotating nozzles, are provided for evenly heating the lumber with microwave. Each set includes four nozzles: a pair of upper nozzles, each upper nozzle positioned on either side of the conveyor belt  12 , and a pair of lower nozzles, each positioned on either side of the conveyor belt  12 . 
     Any known continuous microwave source can be used for delivering the microwave radiation to and through the waveguides. For example, the microwave generator (not shown) can be a stand-alone unit which includes a magnetron, for example, a 150-kW magnetron, electromagnet, power supplies, and additional components such as isolators for protecting the magnetron from back-reflections. Referring to  FIG. 3 , additional components are preferably included for selectively directing a desired range of microwave radiation through a designated opening in a manifold  26  to the waveguides  22  interior to the enclosure  14 . 
     The waveguides  22 , manifold  26 , and nozzles  18  can be formed of any appropriate material, such as aluminum, copper, stainless steel or brass. 
     It is also contemplated to use solid-state microwave emitters known in the art rather than the magnetron system shown. 
     The sets of nozzles  18  are preferably evenly spaced as needed along the length of the enclosure  14  to rapidly and evenly heat and evacuate moisture from the lumber during a heating cycle. As the lumber is heated by the microwave radiation  30  emitted by the nozzles  18 , moisture is transferred from the central areas of a layer (or stack) of dimensional lumber  16  to the outer surfaces of the wood. Removal of the moisture is preferably continuously achieved by circulating air through the enclosure  14  according to any method known to those of ordinary skill in the art. For example, exhaust fans can be appropriately placed to draw air in through one or both ends of the enclosure, creating an air flow along the length of the conveyor belt. Preferably, a circulating air system is used such that the temperature and humidity of the circulating air can be regulated in real-time to maintain a preferred moisture profile of the lumber in accordance with methods known in the art. 
     Referring to  FIG. 3 , in one embodiment, microwave radiation is uniformly applied to heat the portion of the lumber in the enclosure  14  for a period of time and with sufficient intensity to heat and vaporize moisture within the lumber, preferably within a central portion of the lumber, without significant destruction to the ray cell tissue of the wood. The microwave radiation is then interrupted, for example, by modulating, or switching off, the source of microwave, or otherwise mechanically diverting or blocking the radiation from impinging on the wood, to provide a drying (and cooling phase). In certain embodiments of the disclosed system, a drying (and cooling) phase is associated with the microwave cycle. The cycles may operate simultaneously or at certain time delays depending on the moisture levels detected by the sensors of a moisture sensing unit. 
     Moisture is removed from the surface of the lumber during the drying phase by any known method known in the art, such as by circulating air. The drying phase preferably continues for a period of time that is determined by at least one of a number of constantly monitored parameters, such as change in the overall moisture content of the wood, or in the uniformity of a moisture profile within the wood. The microwave heating and drying phases are continued to remove moisture from the lumber, preferably, until a desired final moisture content is achieved. 
     In various embodiments, the intensity of the microwave heating of the lumber is preferably maintained at a level that avoids substantial destruction of the ray cells and wood tissue, preferably, not greater than about 10 W/cm 2 . 
     In other embodiments, the intensity of the microwave heating is raised for at least a portion of one or more heating phases to a range of between about 10 W/cm 2  and 1 kW/cm 2 . 
     In certain embodiments, the heating phase includes the application of microwave radiation to the lumber for a period of time from about 20 seconds to about 40 seconds. In additional embodiments, the drying phases can range from about 30 seconds to a minute. 
     In still other embodiments, the heating phase includes the application of microwave radiation to the lumber for a period of time ranging from about 0.1 second to about 700 seconds. 
     It is understood that each subsequent heating and drying phase can be of differing duration, preferably as determined by monitored parameters, such as the continuing moisture content and profile measurements. 
     In various additional embodiments, the microwave frequency for heating the wood is maintained in a range of between about 0.1 GHz and 300 GHz, more preferably, between about 0.1 GHz to about 24 GHz. 
     In one embodiment, the microwave frequency is maintained between about 2 and 3 GHz, preferably around about 2.45 GHz. 
     In one embodiment, the microwave frequency is maintained in a range between about 750 MHz and 1.2 GHz, preferably between about 850 MHz and about 950 MHz. In other embodiments, also depending on the type of porous or otherwise fibrous material being treated and the currently detected moisture levels of the material, an applied microwave frequency may range from 500 MHz to 10 GHz, preferably 2450 MHz or 915 MHz in a continuous process. Any applicable international standards may also be indicative of the applied ranges as well. 
     The systems and methods of the present disclosure are particularly well-suited to drying dimensional lumber. In typical applications well-suited to the continuous process of the disclosure, the lumber can be from about ¼″ to 3″ thick, 1″ to 12″ wide, and 1 to 24 feet in length. 
     As one example, 1″ thick×3″ wide×40″ long strips of dimensional lumber were dried in about 20-30 seconds under 37 kW microwave radiation for example, at 915 Mhz, is uniformly delivered over the lumber within the enclosure. 
     It is understood that the intensity of the microwave needed to penetrate a predetermined thickness of the lumber will increase in accordance with the moisture content. In other words, as the moisture content is reduced after each heating cycle, the intensity of the microwave is also preferably reduced to prevent unwanted damage to the wood (or other example materials such as plant(s), flower(s), leaves, specimen(s)). It is also understood that the penetration depth of the microwave is a function of the frequency as well as of the properties of the wood (or other example materials such as plant(s), flower(s), leaves, specimen(s)), including moisture content. Accordingly, the moisture content of the lumber (or other example materials such as plant(s), flower(s), leaves, specimen(s)) is preferably monitored throughout the process in accordance with methods well-known in the art and used to adjust the various operating parameters to tune the parameters of the microwave source for optimal performance during the process and, preferably, to vaporize moisture throughout the entire volume of the wood (or other example materials such as plant(s), flower(s), leaves, and/or specimen(s)). 
     It is also desirable to control the orientation of the electric field strength vector E of the microwave radiation. As one of ordinary skill in the art will appreciate, the penetration depth will also depend on the orientation of the electric field vector impinging on the lumber and on the relative orientation of the electric field strength vector relative to the grain of the wood. In one embodiment, the orientation of the electric field is preferably roughly aligned parallel to the grain of the wood. It is also appreciated that the orientation of the E-field vector may differ using a single-mode applicator waveguide, the waveguide being the single applicator. In such mode the orientation of the waveguide determines the orientation of the electric field, either in a parallel direction or perpendicular orientation with respect to the material being dried. In certain embodiments, a series of waveguides can be oriented in a preferred direction for the orientation of the electric field (for example, parallel or perpendicular) and oriented in the opposite direction for the alternate orientation of the electric field. The drying process is affected by mining the electric field with uniform distribution of the microwave field, which mining is also dependent on the material being dried and the desired level of drying. In multi-mode field chambers, the E-field vectors are mixed. For example, at 915 Mhz would not produce as much mixing of E-field vectors. Another example is at 5.8 Ghz, the chamber would experience a typical multi-mode. For any cavity that is larger sized or larger than the cross-sectional area of the waveguide, the field will begin to spread and mixing of modes generally occurs. In such cases, when mixing of modes occurs, some E-fields are oriented parallel or perpendicular to the material and some even dispersing at different angles. The disclosed drying process mines the electric field such that the microwave field is uniformly distributed which results in a more ideal drying process. 
     In other embodiments, the orientation of the electric field is preferably aligned perpendicular to the grain of wood. In still other embodiments, the orientation of the electric field is rotated either from one heating phase to another, or during a single heating phase, from a perpendicular to a parallel orientation. 
     In another embodiment, an RF heating and moisture equalization is initiated either before or after the application of the microwave radiation, and before a drying phase. In a preferred embodiment, the RF heating is applied in combination with the delivery of microwave energy. Though not shown in  FIG. 3 , one of skill in the art will appreciate that volumetric RF heating can be applied to heat the lumber within the enclosure by energizing electrodes positioned on either side of the conveyor belt (or above and below the lumber on the conveyor belt). It will be appreciated that such RF heating will tend to equalize the moisture levels. Accordingly, in one embodiment, microwave heating is applied to preferentially heat, for example, a central portion of the lumber, by proper control of the operating parameters of the microwave, followed by application of RF heating, in order to draw the moisture quickly to the surface, which is in turn, followed by a drying phase. 
     In certain embodiments, the heating phase includes a series of RF pulses that accompany the microwave heating, followed by a drying phase. Referring to  FIG. 4 , for example, in one embodiment, during a heating phase, which can be, for example, between about 10 seconds and 600 seconds in total duration, the microwave heating of the portion of the lumber inside the enclosure  14 , as shown in  FIG. 3 , is accompanied by RF pulses generated by opposing RF electrodes, RF plates or emitters  28 . 
     In certain embodiments a dielectric material can be applied or deposited to the inner walls of the chambers, such as the chambers ( 604 ) and ( 613 ) shown in  FIG. 6A  and described in greater detail below. For example, a dielectric material such as carbon fiber, ceramic material, synthetic resin material, silicon carbide or silicon carbide composite can be applied to the inner wall of the drying chamber. An exhaust module with a vacuum pump system can also be included to prevent unwanted moisture condensation in the drying chamber. The dielectric materials in turn generate heat when microwave energy is applied. This can provide some additional radiant heat to the outer surface of the material being heated and can thereby serve to dry the moisture drawn to the outer surface of the actual material being heated. 
     In one embodiment, the operating parameters of the microwave source are preferably optimized to preferentially heat a central portion of the lumber. The RF is then applied to equalize the moisture profile while simultaneously continuing the heating process to quickly draw the moisture out to the surfaces of the lumber. Preferably, circulating air continuously removes moisture from the lumber even during the heating process. Accordingly, unlike prior art systems that employed microwave drying, moisture can be efficiently and quickly evacuated away from the surface of the lumber and out of the enclosure as it is evacuated, not after it forms a barrier on the surface to further irradiation. As a result, a fairly uniform moisture profile is maintained, similar to traditional cycling of the charging and discharging cycles of traditional kiln drying, but at a much faster rate. In addition, the expense and inconvenient batch process of known RF kilns is avoided, and no defects are imparted to the wood in the process. 
     In one embodiment, the RF pulses are of a duration in the range of between about 0.5 seconds and about 20 seconds. They can also be separated by between about 0.5 seconds and about 20 seconds. Preferably, air is circulating throughout the entire process to continuously draw the moisture away from the wood as it is vaporized and transported to the surface. However, a drying cycle also preferably follows during which no microwave or RF heating is applied. 
     In any of the embodiments, drying/cooling cycles during which there is no RF or microwave radiation can also be provided between heating cycles and may be between 30 seconds to a minute long, or up to about 10 minutes long and can be determined based on the constantly monitored parameters of the wood, circulating air, and internal environment of the enclosure. 
     In addition, a final drying/cooling stage which is substantially longer is also preferred, which can last anywhere from two (2) hours to three (3) days or longer as needed, and the material (or other materials such as plant(s), flower(s), leaves, and/or specimen(s)) being dried. 
     Referring again to the example shown in  FIG. 4 , the electrodes  28  for RF heating are appropriately sized to heat two separated rectangular sections of the lumber as it translates down the conveyor belt. It is appreciated that one of the ways to control RF heating is the manner in which the RF plates or electrodes are coupled, particularly by changing the distance between the electrodes. Therefore, a pair of electrodes are positioned on either side of the conveyor belt (i.e. anode and cathode plates) and an E-field is produced between the plates. The distance between the plates controls the level of RF energy that is applied to the material or load on the conveyor belt. In a preferred embodiment, the performance of the electrodes can be optimized and further controllable, by making one of the plates movable and the other plate set at a particular distance apart. A motorized device set behind the second plate is able to move the second plate closer or further away from the conveyor belt, and thus optimizing the RF drying process for the material being dried. This ability to move one of the pairs of electrode plates minimizes the air gap and reduces any incidence of arcing (e.g., burning of the product and/or the electrode). In a preferred embodiment, the RF plates or electrodes are situated as close to the product and the current is adjusted as accomplished by adjusting the RF generator, also dependent on the dimension of the material being treated. With a larger product, there would generally be a wider distance between the electrodes. 
     Preferably, the RF pulses are generated in a frequency range of between about 2 and 30 Mhz. 
     During the microwave/RF heating, the temperature of the lumber may be from about 100 to 250 degrees Celsius, depending on the type of wood material (or other materials such as plant(s), flower(s), leaves, and/or specimen(s)). 
     In an alternate embodiment, rather than uniformly heat the entire portion of the lumber that is inside the enclosure  14  at any one time with microwave, only a portion of the lumber is irradiated with microwave  30  as it is translated on the conveyor belt, as shown in  FIG. 5 . 
     In additional embodiments, the enclosure is also injected with nitrogen to help evaporate the moisture off the lumber. 
     For example, the sets of nozzles  18 , can be configured to sweep back and forth transverse to the direction of the conveyor belt to generate a number of rectangular swaths of radiation for heating a portion of the lumber. The rectangular swaths of microwave radiation are separated by a fixed distance. The nozzles  18  are staggered between pairs of opposing electrodes  28  along the conveyor belt for the application of RF to each portion of lumber as it translates along the conveyor belt. Accordingly, alternating rectangular swaths of microwave radiation and of RF heating are provided. Additional rectangular drying regions can also be provided along the conveyor belt that are not heated by either microwave or RF to provide drying or cooling “stations.” Additional fans and vents could be placed to preferentially circulate air over these regions. 
     Accordingly, the periods of time corresponding to the RF heating, microwave heating, and drying can be controlled by the speed of the conveyor belt, the length of the rectangular swaths in the direction of the conveyor belt, the separations between the rectangular swaths, and, optionally, also by controlling the periods of time during which each of the microwave and RF emitters are energized. 
     In various embodiments, the nozzles  18  of the present disclosure have an adjustable shape and length for altering the emitted radiation pattern and intensity profile in the dimensional lumber as needed. 
     In any of the embodiments of the present disclosure, various parameters of the dimensional lumber  16  are monitored continuously as the lumber translates along the conveyor belt. Measurements of these parameters are preferably used in a feedback loop to adjust any of the operating parameters of the system  10 . For example, the moisture content and gradient in the lumber can be monitored using various in-line moisture meters known in the art, and various humidity and temperature monitors can be positioned throughout the interior of the enclosure  14  to monitor the environment. The humidity and temperature of the air circulating into the enclosure  14  can be adjusted accordingly to maintain operable conditions for heating and drying the lumber. In addition, the intensities and radiation wavelengths of the continuous microwave and of the RF interceptor can also be controlled in accordance with the parameters that are monitored, as well as in accordance with the type, starting moisture content, and volume of material that is being treated. 
     As one example, power amplifier technology for RF heating systems can be used as both a sensor for the moisture content of the lumber and for subsequent control of the RF power. 
     In order to accommodate different ranges of microwave radiation, the system  10  can also include additional sets of microwave emitters and waveguides that are optimized for different wavelength regimes. The waveguides are generally fed into the cavity and the mode of excitation of the cavity depends on the size of the cavity and frequency of the microwave energy. Thus, in certain embodiments, these additional waveguides may be used with different microwave frequencies applied simultaneously. Additionally, in certain embodiments, the same or varied microwave frequencies may also be applied intermittently. 
     Appropriate energy guiding components selectively guide the desired microwave radiation through corresponding waveguides in the manifold. The optimal microwave and RF range can be manually chosen from a control panel by the operator upon initial setup, based on the type of wood material (or other materials such as plant(s), flower(s), leaves, fresh materials, and/or specimen(s)) and so on, and can optionally also be automatically adjustable during processing, based on the constantly measured parameters of the lumber and of the environment within the enclosure  14 . 
       FIG. 6A  is a preferred embodiment of the present technology. A generator ( 601 ) delivering microwave energy is shown at ( 601 ). The generator ( 601 ) may be configured as a standard microwave generator, including power supply and magnetron heads for operation at varied levels. For example, a 915 MHz generator operates with power ranges up to 100-150 KW, a single 2.45 GHz generator operates at levels of up to approximately 30 KW and a 5.8 GHz generator operates at a power level of approximately 700 W. In certain embodiments, multiple generators may be implemented at certain operable frequencies. Typically, the microwave power supply can be stand-alone with magnetron heads that can be integral to or remotely situated from the power system. Other custom configurations are also possible including configurations that are suitable for power supply systems implemented in international environments. 
     In a preferred embodiment of the disclosed system and method, the microwave generator ( 601 ) having a power of 150 KW can be split four ways in certain embodiments. Four waveguides ( 619 ) are shown in the  FIG. 6 , adapted to extend with the waveguide ( 619 ) flanges that can extend with varied lengths. Generally, hollow conductive metal pipe is used to carry high frequency waves, particularly microwaves. The waveguides ( 619 ) are sealed and connected to the respective openings of each chamber ( 614 ) at connection points ( 612 ). The microwave energy is introduced into the first chamber ( 613 ) via opening ( 614 ). The energy is dispersed within chamber ( 613 ) while a dead zone or microwave attenuation area is formed surrounding the first and second chambers ( 613 ,  604 ) at surrounding portions of chamber  1  ( 604 ) and chamber  2  ( 613 ) as shown in zone areas ( 603 ). It is noted that the microwave attenuation areas or zones ( 603 ) are purposely created to serve the purpose of preventing microwave energy from entering, for example, the RF zones ( 616 ) and ( 618 ). This permits among other advantages, greater control over the drying process including specific targeted heating depending on the mode of operation and the type and cut of material being dried. Chamber  2  ( 613 ) permits the applied energy to be better focused and target. In addition, Chamber  2  ( 613 ) permits the system to maintain better control over the applied energy levels without as much dispersion. 
     The microwave energy is directed to the second chamber ( 613 ) within a close range distance of the wood, plant, leaves, flower, fresh materials, or other materials as it passes along the conveyor belt along zones ( 615 ) to ( 618 ). This in effect, controls the distance of the microwave energy applied to the material, for example, plant(s), flower(s), leaves, specimen(s), fresh materials, and/or wood being dried. The benefit over existing systems is the ability to exert greater control over the distance, direction and rate of penetration of the microwave energy as delivered to the wood, plant(s), flower(s), leaves, specimen, or other material being processed and dried. Any inefficiency associated with prior art systems that merely apply microwave energy to material being dried, are thereby eliminated. Such conventional systems typically experienced greater dispersion of microwave energy. The energy in the disclosed embodiment is not as greatly dispersed but, rather the levels controlled and applied to the materials with greater ability to intelligently target areas of greater moisture. This prevents greater amounts of dispersion of microwave and/or RF energy including the power generally associated with such applied energy. In effect, the energy emitted into the second chamber ( 613 ) is better targeted and the disclosed embodiment can maintain better control over the energy level without as much dispersion of energy. 
     It is noted that the specific dimensions and shape of the chambers may affect the targeted delivery of the energy as shown in  FIGS. 6B-6D  (elements  604 ( b ) through  604 ( d )) with surrounding microwave attenuation zones (elements  603 ( b ) through  603 ( d )) varying also based on the shape of the surrounding chambers ( 604 ( b )- 604 ( d )). The targeted delivery of energy also depends on the type, cut and/or dimensions of the material as well as the uniformity of the applied microwave field. The chambers are designed in certain embodiments to control and focus the microwave energy and promote optimal coupling with the material or load. Additionally dielectric materials such as for example, silicon carbide, carbon, carbon containing resin or carbon fiber, can be used to coat the interior walls of the chambers ( 604 ) and ( 613 ) in order to absorb any stray microwave energy. 
     In the shown embodiment of  FIG. 6A , the first chamber ( 604 ) is used essentially to dissipate the microwave prior to the microwave energy impacting the RF portion. In certain embodiments, the microwave and RF signals may also be combined in one or more of chamber  2  ( 613 ) by including opposing RF electrodes in or near the conveyor belt at zones ( 615 ) and ( 617 ). 
     It is noted that chokes ( 609 ) are included throughout the chambers in order to prevent impedance or blead-off. The impedance brushes ( 607 ) and/or chokes ( 609 ) comprising for example, silicon carbide, carbon, carbon containing resin or carbon fiber, may be used to absorb or “mop-up” any stray microwave energy. Additionally, such brushes ( 607 ) and/or chokes ( 609 ) can cause the microwave energy to be reflected back and/or essentially cause the microwave energy to cancel itself out. The impedance brushes ( 607 ) may be located either under the conveyor belt ( 606 ) or above the conveyor belt, brushing the surface of the conveyor belt ( 606 ). The impedance brushes may be located in the same region as the moisture control device ( 611 ) as radiation absorbers to prevent unintended impedance. Chokes ( 609 ) such as for example, pins, ¼ wave, cut-off or tube chokes, can also be used to separate and isolate chambers from any neighboring irradiation and prevent any impedance blead off. Chokes ( 609 ) are generally situated in the dead zone areas or microwave attenuation zones ( 603 ) situated before and after any of the impedance brushes ( 607 ) and/or surrounding the areas of the chambers. 
     The wood boards, plants, plant(s), leaves, flower(s), specimen, fresh materials, ceramic slabs or other materials that have retained or absorbed some level of moisture and/or oil content level, are loaded onto the conveyor belt ( 606 ). As the board first passes for example, from right to left, from zone  615  to zone  618 , the material first passes underneath the moisture control device ( 611 ) in zone  615 . In certain embodiments, this scanning is accomplished using x-ray, laser, or other known scanning device. The moisture content is processed by a computer processor within moisture control device ( 611 ), for example. The computer processor may scan the board every nanosecond and determines whether for example, the detected levels of moisture require additional exposure to microwave energy or alternatively, increasing or decreasing the speed of the conveyor belt ( 606 ). A signal to increase the speed of the conveyor belt ( 606 ) will decrease the applied energy to the material on the conveyor belt ( 606 ). A signal to decrease the speed of the conveyor belt ( 606 ) will increase the applied energy to the material on the conveyor belt ( 606 ). 
     It is noted that a certain distance between the moisture control device ( 611 ) and any of respective zones adjacent thereto ( 615 )-( 618 ) creates a zone of quiescence so that the material is not being treated with any form of energy in those areas. It is preferable to use radiation absorbers such as impedance brushes ( 607 ) to control and reduce the unintended incidence of unwanted irradiation. Chokes ( 609 ) may also be used throughout the zones ( 615 )-( 618 ) to separate and insulate the chambers from neighboring irradiation. 
     The moisture control device ( 611 ) will detect the moisture level of the material that is currently passing on the conveyor belt as the material passes through successive zones, namely ( 615 )-( 618 ). The moisture control component ( 611 ) may include moisture and temperature detection sensors that send an electric signal to the tuning forks ( 610 ) such as for example, stub tuners, transmitting the detected temperature and/or moisture level of the material. The tuning forks ( 610 ) in turn, may send a signal to the louvers&#39; locations at elements ( 605 ). The tuning forks ( 610 ) make an adjustment inside the waveguides ( 619 ) changing the harmonics of the microwave energy as emitted to the chambers and subsequently, as emitted to the material moving along the conveyor belt ( 606 ). The tuning forks ( 610 ) function to more effectively couple the microwave energy into the load or material and minimize the reflected power. The tuning forks ( 610 ) may change the impedance of the microwave energy to better match the level of the load. The moisture control device ( 611 ) may also interface with the microwave generator ( 601 ) controls, such as for example, a PID interface and controller connected thereto that can adjust the power of the microwave energy upon receipt of a signal to either increase or decrease the power of microwave energy. An automatic stub tuner may be implemented in certain embodiments with fully integrated feedback model to send appropriate signals to increase or decrease the impedance of the microwave energy and/or signal the microwave generator ( 601 ) to increase or decrease the power of the microwave. Such stub tuners may be implemented with microprocessor controllers. 
     The processor or moisture control module ( 611 ) may also send at least one signal to the louvers ( 605 ). The sensors may be of any known in the art such as optical sensors, RF sensors and/or infrared sensors. Motion detection sensors may also be included in certain embodiments to detect the speed of the conveyor belt. 
     The louvers ( 605 ) which include a number of fixed or operable blades mounted in a frame, can receive a signal to rotate to an open position, up to a 90° angle. In the event, a smaller amount of energy is desired to pass through the louvers ( 605 ), the louvers ( 605 ) will receive a signal to rotate the blades from a more open position to a lower degree of rotation, such as between 90° to 45° as shown in  FIG. 8A . A signal may be received to rotate the louver blades to an even lower degree of rotation from 45° to a closed position of 0° as shown in  FIG. 9A . In a closed position, no energy can be transmitted and therefore, no energy is delivered to the material as it&#39;s passing in the particular zone ( 617 ) or ( 615 ). The ranges of louver ( 605 ) openings are from a rotational range of 0° to 90°. The highest energy level can be transmitted is when a louver ( 605 ) is fully opened at 90° as shown in  FIG. 9B . A closed position of 0° is able to block the delivery of any microwave energy as the material travels lengthwise on the conveyor belt to the next zone of energy delivery as shown in any one of zones ( 615 ) to ( 618 ). 
     It is noted that the spacing of the louvers ( 605 ) does not significantly interfere with application of the microwave energy in its open position at 90°. In addition, any potential arcing is minimized by fully grounding the louvers ( 605 ). Consideration of any potential for arcing is also minimized by controlling the emitted microwave field&#39;s intensity. 
     The speed of the conveyor belt ( 606 ) is controllable and variable based on the detected conditions of the material as it passes the zones of the conveyor belt. For example, when a detected level of moisture signal is sent to the conveyor belt controller, the controller is able to increase or decrease the relevant speed of the material as it passes the zones of energy ( 615 ) to ( 618 ). Additionally, the variable of delivery of energy as signaled by the moisture control device ( 611 ) to the tuning forks ( 610 ), may transmit a signal the tuning forks to increase or decrease the level of microwave energy delivered to any one of the chambers ( 604 ) drying the material at any of the particular zones ( 615 ) or ( 617 ). Louvers ( 605 ) operate in conjunction with the tuning forks ( 610 ) to more intelligently target the areas of the material that require increased or decreased energy as the material passes in the zones ( 615 ) to ( 618 ), in particular at zones ( 617 ) and ( 615 ). 
     It is noted that the first location of the moisture control device ( 611 ) as the board just enters the machine, is shown in this embodiment just entering zone ( 615 ). At this first moisture control device ( 611 ) the moisture control device includes scanners, for example an x-ray scanner, that identifies the type of material, for example the cut of the wood (or other material) and may also detect the moisture level. The cut of the wood includes cuts such as for example, plain sawn, rift and quarter sawn cut. In connection with the detected cut of wood (or other properties of other example materials), the applied microwave energy may differ. Penetration of the microwave or RF energy will differ dependent on the difference in cuts of wood (or other properties of other example materials). 
     Once the material has been treated with microwave energy at zone  615 , it will undergo detection by the moisture control device ( 611 ). The x-ray scanner of the moisture control device ( 611 ) is also able to adjust the emitted RF energy module or device ( 608 ) that is applied in zones ( 616 ) and ( 618 ) by sending a signal to the RF energy module or device ( 608 ). The material will next be passed along on the conveyor belt ( 606 ) to zone ( 616 ), at which time, RF energy ( 608 ) is applied to the wood, plant(s), leaves, flower(s), specimen, fresh material, or other material being dried. 
     It is noted that the portion of the wood, plant(s), leaves, flower(s), specimen, fresh material or other material being targeted, depends on the cut and dimensions of the material. In addition, the moisture levels of the material impact how the applied RF energy targets the surface or core layers of the material. RF having a lower frequency has a much longer penetration depth and generally, can heat the entire thickness of for example, a wood board. However, microwave can preferentially heat the surface until enough water is evaporated for the penetration depth to increase (since less water is now absorbing the microwave energy), and then can heat the core. At that point, microwave can heat the interior of the board hotter than the surface (because the surface is radiating and losing heat). Also, moisture has condensed on the surface of the example, wood board, the RF generally targets higher areas of moisture and may preferentially heat the area with more water, which is the surface. Therefore, the RF energy is known to targets the outer layers of the material, for example, plant(s), leaves, flower(s), specimen, fresh materials, or wood but, has a longer penetration depth that it is known to reach the core of the material. While microwaves do provide for greater heating intensity, they are limited in penetrating deeply enough and/or providing uniform heating. Therefore, the disclosed combination of RF and microwave heating within same or alternate zones ( 615  to  618 ) creates a process for more uniform heating of the material that is also capable of drying the inner core regions regardless of moisture levels or thickness and/or size of the material which variables all impact how thorough the material is dried. 
     The material enters the area of the next moisture control device detection device ( 611 ). Any further adjustments to any emitted microwave energy are made by a signal delivered from the moisture control device ( 611 ) to the tuning forks ( 610 ), which can adjust the microwave harmonics. In addition, the moisture control device ( 611 ) may send a signal to the louvers located in the next upcoming zone ( 617 ) in order to adjust the level of microwave delivery by adjusting the degree of opening of the louvers ( 605 ) by either increasing the opening of the louvers ( 605 ) to a maximum of 90° or decreasing to a minimum of 0° rotation. The degree of rotation of the louver will impact the angle of penetration of the microwave signal. Therefore, the system will detect the best angle of rotation of the louver ( 605 ) to reach the best level of penetration. The cycle may repeat for the length and number of zones that the apparatus may be configured to comprise and/or when it is determined that the material, for example, wood, plant(s), leaves, flower(s), specimen, fresh material(s) or other material no longer requires treatment. It is also noted that the RF energy ( 608 ), in certain embodiments may also be deliverable by solid-state RF power devices. In certain embodiments, infrared energy may also be use either in combination with RF or in separate zones in which infrared energy may also applied to the materials in order to heat the materials. Infrared radiation may also be used to remotely detect the temperature of the material. Infrared heaters may be achieved using known infrared energy sources, a heat exchanger and a fan that blows air into the exchanger to disperse the applied heat. 
     While particular embodiments have been described herein for delivering microwave to either the entire portion of the lumber within the enclosure or to separated rectangular swaths of the lumber using nozzles connected to channel waveguides, it should be appreciated that various other configurations for delivering microwave for heating the lumber are also contemplated. For example, slots can be provided in microwave waveguides positioned above the lumber. In what are known as a leaky waveguide configuration, appropriate microwave guides can be positioned below the slots and in certain embodiments, rotated in a sweeping motion to deliver either uniform microwave radiation to the entire portion of lumber within the enclosure, or to deliver separated rectangular swaths. Such semi-standard configuration permits the application of microwave energy to the material along the length of the waveguide via the slots configured along the length of the waveguides. In addition, various solid-state emitters are known in the art, which provide various additional compact solutions. 
     The system and method of the present disclosure advantageously replace prior art batch processing systems and methods for heating and drying materials in a kiln with a continuous processing technique. Accordingly, as dimensional lumber for example, is cut to process a particular order, it can be immediately placed in the continuous feed system and dried in as little as 15 minutes. In contrast, traditional kiln processes that provide heating by steam, hot water coils and so on can take from 10 to 30 days to complete a batch, depending on the species of material, for example the wood, flower(s), leaves, and/or plant(s) and the more energy-intensive and expensive RF-vacuum kilns take up to 5 days to complete a batch. Furthermore, running any of the prior art kilns at a reduced capacity significantly increases the relative cost of the final product. Finally, the microwave treatment of the present disclosure also effectively rids the lumber from pests, eliminating the need for the application of pesticides such as methyl bromide in the final product. Accordingly, the present system and method offer additional environmental benefits as already described above. 
       FIG. 6B  is an alternate embodiment with chambers ( 604   b ) shaped with a narrow mouth that extends into to a wider chamber. The dead zone or microwave attenuation zone is located in this configuration surrounding the chamber at  603   b.    
       FIG. 6C  is an alternate embodiment with chambers ( 604   c ) shaped with parallel extending walls. The dead zone is located in this configuration surrounding the chamber at  603   c .  FIG. 6D  is an alternate embodiment with chambers ( 604   d ) shaped with a narrow mouth extending radially to a wider chamber. The dead zone is located in this configuration surrounding the chamber at  603   d . In such preferred embodiment, the shape of the chamber is known to minimize reflections within the chamber ( 603   d ). 
     As described above regarding the varying degrees of rotation of the louvers,  FIG. 7  is a top perspective view of the louver blades ( 710 ) as connected to a rotating mechanism ( 740 ) that extends the length of the blades and is guided by element ( 750 ). The louvers ( 710 ) are attached to the louver structural supporting elements ( 720 ) and ( 730 ). 
       FIG. 8A  illustrates the louvers apparatus ( 800 ) with louvers ( 710 ) as rotated at 45° angles with respect to the x-axis or horizon.  FIG. 8B  illustrates a cross-sectional view of a louver ( 710 ) including the inner mechanics ( 810 ) of the rolling mechanism ( 80 ) as shown in  FIG. 8A  that permit the louvers ( 710 ) to rotate from 0° to 90°. 
     In certain aspects or embodiments, disclosed is a vertical feed conveyer (VFC) drying system  100  that implements microwave and/or RF drying, as shown for example in  FIG. 10 . Such VFC drying system  100 , may be integrated with an embodiment of the drying system described for example in connection with  FIGS. 1-6C , or provided as a separate standalone system. In addition, such VFC system  100  may be customizable as integrated units that can be attached to multiple VFC system  100  units as required for the drying system operation and the particular plants and/or materials being dried. Additional implementations provide for an embodiment in which the VFC drying system  100  is a portable mobile unit that includes a power supply unit and can implement such drying system operation in the fields. 
     More particularly, in certain aspects or embodiments disclosed is a vertical feed conveyer (VFC) system  100  as shown in  FIG. 10 , that is a novel drying system that eliminates the traditional horizontal conveyer belt system used in conventional drying systems. The VFC system  100  is vertically integrated into the drying chamber using a top track conveyer system  115 . In certain embodiments, the top track system can turn upwards (vertically) or horizontally creating a loop (left or right) for the return to the input side  101 . For example, while entering the VFC system  100  and hence, entering the drying chamber  102 , the top track system may complete a full track while looping back horizontally from the output side  110  for the return to the input side  101 . The track loop of the track conveyer system  115  may be configured to operate external to the drying chamber  102  for the return route from the output  110  side back to the input side  101 . 
     Alternatively, the track loop of the track conveyer system  115  may be configured to operate in cooperation with the VFC drying system  100 , specifically for the items/plants to be vertically dried, and hence, vertically received by the drying chamber  102  for drying treatment with the VFC conveyer track system  115  configured to be located entirely within the drying chamber  102 , or otherwise, configured as a hybrid design, and hence, located partially external to and partially within the drying chamber  102 . Such configurations would both operate the drying process with commencement of the drying cycle in the microwave (MW) chamber portion  105  through the rest zone  108 , and then proceeding to the final drying phase in the RF chamber portion  106 , in standalone system units. The track loop of the track conveyer system  115  may also be configured to further cultivate/process the plant/flowers (for example, cannabis plant) for distribution. 
     The track of the track conveyor system may be configured to further operate in a clockwise or counterclockwise direction (i.e., forward direction and/or reverse direction(s)). In such reverse configurations, the VFC system  100  would commence an RF chamber  106  drying cycle first, followed by rest zone  108 , moisture monitoring  107  and tempered air  109  cycle, and then MW chamber  105  distribution of microwave energy or waves would be the next drying cycle. 
     Other contemplated embodiments of the VFC system  100  may be implemented with n number of multiple VFC systems  100  integrated or interconnected thereto (in various configurations) to repeat the MW chamber  105  zone of delivery or distribution drying cycle, the rest zone  108  of delivery cycle and then the RF chamber  106  zone of delivery or distribution drying cycle. The drying cycle can also operate in a reverse direction with the RF chamber  105  drying cycle or distribution/zone of delivery first, then the rest zone  108 , followed by the MW chamber  106  drying cycle or zone of delivery/distribution. Additional embodiments permit variability within such system configurations within the standalone VFC system  100  alone. For example, the system may begin the drying cycle with RF chamber zone of delivery  106  drying cycle, rest zone of delivery  108  cycle, followed by MW chamber  105  zone of delivery or MW chamber  105  distribution drying cycle. 
     In certain embodiments, the VFC system  100  shifts the traditional horizontal feed and converts the entire chamber for example 90 degrees counterclockwise. Such counterclockwise turn will shift the microwave chamber  105  and RF chamber  106  delivery system on the side of the drying chamber as compared to traditional drying chamber set-ups where the microwave and RF delivery systems are generally located on the top of the drying chamber. 
     The VFC system  100  is vertically integrated into the drying chamber using a top track conveyer system  115  shown in  FIG. 10  (and further, as shown and described in connection with  FIGS. 11-13B ). The top track loop in certain embodiments will turn or shift following its track upwards for the return back to the input side  101  of the VFC system  100  via the top track conveyer system. In certain embodiments, an operator may hang for example cannabis flower(s) or plants, upside down from a spring tension clamp (or alternatively hook) connected to the track, before entering the microwave and RF drying chamber  102 , which begins with the initial phase or stage of the drying cycle for example, at input  101  to the drying chamber  102 . 
     In example embodiments, the VFC system  100  supports hanging plants, flowers, cannabis plants/flowers or other vegetation or items, upside down using for example, spring tension clamps (or hooks) that are evenly spaced and permanently affixed to the top track of the conveyor system  115 . The equal distance (equidistance) between such clamps or hooks (and hence, the items or plants/flowers being dried) can be fine-tuned prior to the drying cycle in order to optimize the drying cycle and process. The vertical track conveyor is adapted to permit a d length predetermined distance between the items or plants/flowers being dried. In addition, the equidistant d length between the clamps, hooks or other mechanism holding/securing the items being dried vertically, permits the VFC system  100  operator, administrator, or other automated administrator of such VFC system  100 , to keep track of how many items, plants, flowers, (measured in weight for example, pounds (lbs.) or tons (tonnage)), etc. Such plants/flowers or material are being dried at a given point in time, or a given/predetermined interval or span of time. Hence, the VFC system  100  permits automated tracking of such drying cycle and related operations, in certain aspects or embodiments. 
     In certain embodiments, the flowers or plants, for example cannabis flower and/or plants may be hung upside on the clamping mechanism of the automated vertical track conveyer  115  with an additional spin cycle in which a spin-like system similar to flip spinners as shown in  FIG. 14  can be implemented to optimize the drying of such plants or flowers and improve the outcome of the drying cycle. An alternate clamp mechanism can be implemented for example, a three clamp or a cluster of n number of clamps or hooks can be used. Such cluster of n clamps or hooks can be implemented by being affixed to the vertical track conveyer system  115  at one or m number of connection points. 
     There is scientific evidence as to the reason such VFC system  100  implementing a vertical system that permits upside down drying of plants, vegetation, flowers, etc. The cannabis flower, plants, vegetation, and other items that are dried, in particular flowers or cannabis flower, are dried upside down or inverted downwards with their stem ends connected to the vertical track conveyer system  115 , in order to promote the “full flower effect”. In fact, the drying process is crucial to the flavor and efficacy of certain plants, vegetation, and flowers. 
     In certain aspects or embodiments, it is known that drying certain plants properly, for example cannabis flower, is crucial as it retains the flavor of the strains, and further converts the tetrahydrocannabinolic acid (THCA) into tetrahydrocannabinol (THC) in cannabis plants, for example. THCA serves as the biosynthetic precursor to THC. Without a proper drying process, one risks losing flavor and significant potency, and hence, even potential medical uses, for the harvested plant/flower. 
     When cannabis plants or flowers for example, are ready to dry, they are generally stored in a dark area to stop the photosynthetic process. In certain embodiments, this area generally remains between 62° and 64° F. with 60-70% humidity. The flowers are generally sticky at this juncture and are positioned to be hung upside down. So, the whole plants are positioned to dry upside down so their plant nutrients and/or nourishment can still circulate with the plants still “functioning” as if they are alive. The plants will use their chlorophyll as a last energy resource because the roots cannot absorb any water and the leaves aren&#39;t receiving any light. Much of this energy will be diverted to the flowers so the cannabis plant or other plants/flowers can still reproduce, in certain example implementations. 
     In certain disclosed embodiments, the plants are hung upside down to dry very slowly so the plants will break down chlorophyll and convert starches into sugar. This process will ultimately activate the tetrahydrocannabinol (THC) and enable the full flavor and aroma, in the buds to be produced by the plants which will enhance various uses, including disclosed medical uses. 
     Another aspect of the drying process is to prevent the growth of mold. While the drying process requires that it be tempered, the growth of mold is a concern. In fact, the disclosed vertical feed conveyer system  100  is implemented so as to customize, optimize and/or temper the drying process according the particular material, item or plant/flower type being dried, but also used in preventing mold from growing on leaves or flowers. The system may implement a dehumidifier, a dehumidifying drying phase, and/or combination of RF and/or MW heating to speed up the drying process or even to temper the length of drying time as required, to prevent the growth of mold and/or enhance and even optimize the process of breaking down chlorophyll and/or conversion of starches into sugar in plants/flowers. 
     In certain disclosed embodiments, the plants or flowers may be hung vertically and upside down at a pre-determined distance apart from neighboring plants or flowers, in order to prevent contact between the plants and further ensure the plants are not in contact with any neighboring plants positioned on the track conveyor system  115  during the drying cycle process. 
     The process of hanging the plants or flowers vertically upside down tricks the plants into continuing to thrive as if they are still alive, and as the juices and nutrients continue to flow throughout the plant. The VFC system  100  implements a system that permits a tailored drying process that keeps the plants/flowers alive as long as possible. In such manner, the chlorophyll can be converted into glucose. This in turn, renders a flower/plant with greater flavor and higher yield. The plant will use the remaining chlorophyll as a last energy resource because the roots can no longer absorb water and the leaves are no longer absorbing light. All this energy actually goes to the flower portion so that plants can reproduce. The chlorophyll will be converted into sugar. In certain embodiments, a stable temperature between 17° C. to 18° C. with humidity levels between 60-70% can be implemented by the VFC system  100 , so the plant(s) won&#39;t dry out too quickly. The drying cycle of the disclosed vertical feed conveyor drying system  100 , can be customized to optimize the drying cycle to prevent mold from growing and optimize the yield and/or uses for the dried plants/flowers. In certain aspects or embodiments, the VFC System  100  is also used as non-pesticide fumigation. 
     Some plant cultivators remove leaves while drying their plants, but this practice is not generally advisable in certain disclosed embodiments for the following reasons: plant leaves contain nutrients the plant will use to ripen, leaves protect the buds and ensure they dry slowly, and leaves can reduce the risk of mold growing. In certain embodiments, larger leaves may be removed for the purpose of reducing the plant mass and chlorophyll. Reducing the plant mass permits the plants to dry more quickly. Moisture may evaporate through the leaves, which reduces the risk of mold on the flowers. The leaves form a protection barrier for the flowers because as the leaves dry, they will generally bend around the flowers and protect them. 
     Should mold begin to grow on the flowers/plants, speeding up the drying process and/or a dehumidifying drying phase can be used to treat and optimize the drying process in plants/flowers in certain embodiments of the disclosed VFC drying system  100 , in particular in the reduction of mold during one or more of the drying cycles. 
     In certain embodiments, larger flowers may even be cut into smaller pieces and secured to the vertical conveyer system  115  upside down or otherwise, vertically. 
     Referring back to  FIG. 10 , the input  101  to the drying chamber  102  is automated via the track mechanism of the track conveyor system  115 . In certain aspects or embodiments the first step in drying for example cannabis plants/flowers, to achieve full flower effect and greater range therapeutic uses, the cannabis plant proceeds to the microwave chamber  105  unpruned for irradiation of microwave energy. 
     In certain aspects or embodiments, the cannabis plant enters the drying chamber  102 , and begins the drying cycle in the microwave chamber  105 , un-pruned. In particular, the plant leaves remain on the plant in order to maximize water evaporation and higher chlorophyll levels during the drying cycle. Microwave heat is applied/used because it is a dielectric and will draw out the most moisture quickly through the flowers/leaves and bring the chlorophyll that is within the plants stem to the cannabis plant trichomes. Hence, photosynthesis will occur initially in the MW chamber  105  drying cycle. Next, cannabinoids, terpenes, and flavonoids are produced within the trichrome cells through biosynthesis, in which enzymes catalyze a series of chemical reactions to produce complex molecules from simple (smaller) molecules as described in greater detail hereinbelow in connection with  FIGS. 15-16 . Such biosynthesis phase occurs within the RF chamber  106  drying cycle. 
     In such fashion, all the chlorophyll can be converted into glucose, which generates more flavor and higher yield. Higher THC levels and chlorophyll turn into glucose in the RF chamber portion  106 . The plants/flowers will generally use its chlorophyll as a last energy resource since the roots cannot absorb any water. As the cannabis plant initially travels through the Microwave chamber  105 , water is evaporated through the flower leaves. All this energy transmits to the flowers/trichomes/buds, thereby initiating the cannabis plant to begin stages of the “full flower effect”. 
     During the various drying stages, the system  100  aims to keep the plant alive as long as possible. In such fashion, the plant/flower is in preferred embodiments positioned upside down. Much of the chlorophyll can then be converted into glucose, which generates greater flavor and higher yield, and higher THC levels. The plant dries faster if the larger leaves are removed because the plant itself has little mass and then less chlorophyll. Removing the leaves, reduces the total mass and hence, the plant(s) tend(s) to dry out more quickly. Any moisture will evaporate through the leaves thereby reducing the risk of mold on the flowers, so it a preferred embodiment, the leaves are left on the plant(s). The leaves form a barrier of protection for the flowers, because of the bent around the flowers formed by the leaves, during the drying process. 
     While the THC in cannabis plants may be inactivated, this activation can be significantly expedited with combination of applies microwave and RF heating. If the drying process is not done correctly, the effect will not be as strong and creates spoilage rather quickly. In addition, the taste of for example, cannabis plant would taste more bitter if the drying process is not done in an effective manner. Hence, the VFC system  100 , works to trick the plant into thinking it is still alive so that the nutrients, juices, chlorophyll still circulation but the plants are hung vertically upside down in a preferred embodiment. Hence, the plant will use any remaining chlorophyll as a last energy resource since the roots cannot absorb and water and the leaves are not absorbing any light. The applied Microwave energy in the MW chamber  105  creates the photosynthesis process. 
     The second phase of the drying VFC system  100  drying cycle is commenced by drying the cannabis plant/flowers for the full flower effect in the rest zone delivery chamber  108 , as shown in  FIG. 10 . The rest zone  108  includes tempered air  109  that is introduced in the area between the microwave distribution chamber  105  &amp; RF distribution chamber  106 , referred to as the “Rest Zone” delivery chamber  108 . In certain example embodiments, the temperature is maintained between 17° C. and 18° C. The humidity is leveled between 60-70% in the cool down/rest zone delivery chamber  108 . In certain aspects or embodiments, the rest zone  108  is also used in order to keep the microwave and RF waves from impeding with each other. Hence, the rest zone  1008  acts as an impedance zone in certain embodiments and/or changes/maintains the respective/desired humidity levels as well. The rest zone is considered key to the drying cycle because it permits the cannabis fibers to relax and become engorged with chlorophyll. The key step in achieving the full flower effect is by maximizing chlorophyll amounts and initiating the biosynthesis step occurs in the RF chamber  106 . A viewing window  104  can be used to visually inspect the status of the drying of the plants or materials. The rest zone  108  can include the introduction of tempered air  109  and/or moisture monitoring  107  using moisture sensors, for example, to determine the level of moisture of the plants, flowers or materials that are present in that particular rest zone  108 . The tempered air  109  and/or moisture monitoring can also be introduced during the MW chamber  105  drying phase and further during the RF chamber  106  drying phase. In certain aspects or embodiments, the moisture monitoring  107  process is implemented during all drying phases of the VFC system  100 , beginning with the MW chamber drying cycle  105 , next during the rest zone  108  drying cycle, and further during the RF chamber  106  drying cycle (and in reverse drying cycle embodiments, the reverse direction would be implemented). 
     In particular, during the second phase of the cultivating sequence, in order for the cannabis plants to achieve the “full flower effect”, the VFC system  100  performs treatment of the cannabis plants mostly in the rest zone  108  cycle. During this cycle, fibers retake their shape, maximizing the most amount of chlorophyll of the cannabis mostly during the rest zone  108  cycle. The introduction of cool down or tempered air  109 , achieves the cooling of the plant or cannabis flower in order the draw the maximum amount of chlorophyll to the buds. The rest zone  108  in certain aspects or embodiments, also prevents the microwave energy and RF energy waves from impeding with each other and/or obstructing such transmission of either form of waves (whether MW or RF waves/energy). The VFC system  100  will generally seek to dry certain plants more slowly, so the plant can use all of its chlorophyll, and convert it into sugar without using any fans or heaters. In certain example implementations, after even a few seconds in the RF chamber  106 , a cannabis plant/flower will change and the leaves will bend around the flowers. In certain aspects or embodiments, after about 2-3 minutes of treatment in the RF chamber  106 , the leaves will dry but the flowers and/or stem may be flexible and sticky. The resin falls off easily so such plants are handled with great care so as not to cause dryness. 
     The VFC system  100  will constantly monitor the moisture present in the flowers/plants as it moves throughout the MW chamber  105 , and then through the RF chamber  106 . The RF chamber  106  introduces an RF wave oscillating at a lower frequency, therefore the heating process is slowed down and causes the water molecules to reverse polarity. This physical and/or chemical change(s) marks the beginning of biosynthesis. 
     Shown in  FIG. 11  is a perspective view of the vertical feed conveyer (VFC) drying system  100 , in particular a frontal view, in accordance with an embodiment of the present disclosure. The VFC conveyer track system  115  holds the plant/flowers or other materials vertically along the track and can loop at turning point end(s)  120 , out of the output  110  and return back into the input  101  to commence a MW drying cycle, followed by a rest zone  108  cycle, and then followed by an RF drying cycle as described in connection with  FIG. 10  hereinabove. In particular, shown is a frontal view including a viewing window  104  to observe the drying results and/or status of the VFC drying system  100  cycle(s). The drying chamber portion  102  includes the MW chamber distribution and the RF energy/waves chamber distribution. The MW and RF drying chamber  111 , is clad and/or lined with aluminum type materials. The MW/RF shell  118  is comprised of a composite material. This lining improves the cost-benefits of such disclosed design over known drying systems. In addition, one or more portions of the chamber will include carbon materials which improves the drying efficiency and related costs. 
     The moisture catcher/water collector  121  as shown in  FIG. 11 , may further include a drain or purge that may be used later to draw such fluids collected during the drying cycle(s) or processing and/or such moisture may further be drawn, undergo additional processing/extraction, and/or used for later industrial/medical/therapeutic applications. 
     The diagonal shaded portion in  FIG. 11 , represents the bristles or MW/RF choke(s)  103  that is used to prevent impedance or blead-off. The impedance brushes, bristles and/or MW/RF chokes ( 103 ) comprising for example, silicon carbide, carbon, carbon containing resin or carbon fiber, may be used to absorb or “mop-up” any stray microwave energy. Additionally such brushes and/or chokes ( 103 ) can cause the microwave energy to be reflected back and/or essentially cause the microwave energy to cancel itself out. The impedance brushes or MW/RF chokes ( 103 ) may be located as shown in  FIG. 11 , or in  FIG. 12 , as described further hereinbelow. In certain example embodiments, the impedance bristles ( 103 ) may be located in the same region as the moisture control device to act as radiation absorbers to prevent unintended impedance. Bristles or MW/RF Chokes ( 103 ) such as for example, pins, ¼ wave, cut-off or tube chokes, can also be used to separate and isolate chambers from any neighboring irradiation and prevent any impedance blead off. Bristles or MW/RF chokes ( 103 ) can also be implemented and configured to be located in-between chambers. As an example, bristles or MW/RF chokes ( 103 ) are located between MW chamber ( 105 ) and rest zone ( 108 ) chamber, and also located in-between rest zone  108  chamber and RF chamber  106 . 
       FIG. 12  provides a perspective view of the vertical feed conveyer drying system  100 , in particular an input  101  view, in accordance with an embodiment of the present disclosure. In example VFC drying system  100  shown in  FIG. 12 , the drying system includes a plant or cannabis attachment portion  119  following the input  101  portion. The cannabis attachment portion  119  is located at the clamp attachment to the moving VFC conveyor system  115  and/or associated conveyor track  115 . The diagonal shaded portion of the MW/RF chamber  111  in  FIG. 12 , represents the bristles or MW/RF choke(s)  103  that are used to prevent impedance or blead-off as describe in connection with  FIG. 11 . The RF distribution chamber  105  and MW distribution chamber  106  introduce the RF and/or MW energy to the MW/RF chamber  111  depending on the phase of the drying cycle that is occurring. The viewing window  104  is also shown in  FIG. 12 , albeit more prominently shown in  FIG. 11 . 
     The MW and RF drying chamber  111 , is clad and/or lined with aluminum type materials. The MW/RF shell  118  is comprised of a composite material. This lining improves the cost-benefits of such disclosed design over known drying systems. In addition, one or more portions of the chamber will include carbon materials which improves the drying efficiency and related costs. 
       FIG. 13A  provides an additional view of the microwave and RF chamber  111  specifically a side perspective view of the vertical feed conveyer drying system  100 , in accordance with an embodiment of the present disclosure. The VFC track conveyer  115  includes a track with a clamping mechanism  141  to secure the plants/flowers or other items being dried vertically and in other embodiments, upside down. 
     In particular, the VFC system  100  supports hanging plants, flowers, cannabis plants/flowers or other vegetation or items, upside down using for example, spring tension clamps (or hooks) to clamping mechanism  141 ,  145  that are evenly spaced apart and permanently affixed (or configured to be attachable and/or detachable) to the top track of the conveyor system  115 . The equal distance (equidistance) between such clamps or hooks (and hence, the items or plants/flowers being dried) can be fine-tuned prior to the drying cycle in order to optimize the drying cycle and process. The vertical track conveyor  115  is adapted to permit a d length predetermined distance between the items or plants/flowers being dried. In addition, the equidistant d length between the clamps, hooks or other mechanism  141 ,  145  holding/securing the items being dried vertically, permits the VFC system  100  operator, administrator, or other automated administrator of such VFC system  100 , to keep track of how many items, plants, flowers, (measured in weight for example, pounds (lbs.) or tons (tonnage)), etc. Such plants/flowers or material are being dried at a given point in time, or a given/predetermined interval or span of time. Hence, the VFC system  100  permits automated tracking of such drying cycle and related operations, in certain aspects or embodiments. The MW/RF chamber  111  as shown in  FIG. 13A , and drying cycles can be accessed via the VFC track conveyer  115 , as the VFC system  100  progresses on its track  115  in a continuous (but, controllable) feed, through various drying phases/cycles through the MW/RF chamber portion(s)  111 . The height from floor to top of VFC conveyer/track  115  is a total height shown at label  146 . The height from floor to the VFC conveyor/track  115  is a total height shown at label  147 . 
       FIG. 13B  provides a top view perspective of the vertical feed conveyer drying system  100 , in accordance with an embodiment of the present disclosure. The VFC track conveyer  115 , in particular, the frame carousel portion has a width shown at label  143  and total length shown at label  144 , as shown in  FIG. 13B . As described in connection with  FIG. 13A , the VFC system  100  supports hanging plants, flowers, cannabis plants/flowers or other vegetation or items, vertically and/or upside down using for example, spring tension clamps (or hooks) to clamping mechanism  141 ,  145  that are evenly spaced apart and permanently affixed (or configured to be attachable and/or detachable) to the top track of the conveyor system  115 . The equal distance (equidistance) between such clamps or hooks (and hence, the items or plants/flowers being dried) can be fine-tuned prior to the drying cycle in order to optimize the drying cycle and process. The vertical track conveyor  115  is adapted to permit a d length predetermined distance between the items or plants/flowers that are being dried. In addition, the equidistant d length between the clamps, hooks or other mechanism  141 ,  145  holding/securing the items being dried vertically, permits the VFC system  100  operator, administrator, or other automated administrator of such VFC system  100 , to keep track of how many items, plants, flowers, (measured in weight for example, pounds (lbs.) or tons (tonnage)), etc. Such plants/flowers or material are being dried at a given point in time, or a given/predetermined interval or span of time. Hence, the VFC system  100  permits automated tracking of such drying cycle and related operations, in certain aspects or embodiments. The MW/RF chamber  111  as shown in  FIG. 13A , and drying cycles can be accessed via the VFC track conveyer  115  as it progresses on its track in a continuous (but, controllable) feed, through various drying phases/cycles through the MW/RF chamber  111 . 
       FIG. 14A  illustrates an enlarged view of the top conveyer track and related mechanism used in the vertical feed conveyer drying system  100 , in accordance with an embodiment of the present disclosure. The track  157  can be configured to pivot upwards or remain horizontally level, as it progresses through the MW/RF chamber(s)  111  through various drying phases or cycles. The clamp mechanism  155  securely affixes the attachment juncture points  159  thereto. The track  157  includes an equi-distant d distance between each entry securing point  158  at which one or more items, plants/flowers or other material(s) can be secured to the track  157  via clamps, hooks  170  (as shown, for example in  FIG. 14B ) or other securing mechanism for entry into and for undergoing drying treatment through the MW/RF drying chamber  111 . 
       FIG. 14B  provides an illustration of a sample mechanism to clamp/hook the plants/flowers or other material vertically to the vertical feed conveyer track mechanism shown for example in  FIG. 14A , in accordance with an embodiment of the present disclosure. The clamp or hook portion  171  can be affixed to the securing connection points  158  shown in  FIG. 14  A. the plants/flowers or other materials are hung vertically from the hook securing portions  173 ,  174 . Such hook securing portions  173 , 174  are situated at an equi-distance d from neighboring Hook securing portions  173 ,  174 , and hence can be configured to maintain a distance d that prevents contamination or any physical cross-over. However, once plants are harvested generally, there isn&#39;t a concern for physical cross-over. The plants/flowers or other materials are secured on a neighboring hook securing portion  173 ,  174  or any hook securing portions  173 ,  174 . The neighboring hooks  174 , for example, are separated by a distance di while non-neighboring hooks, for example  173 , may be separated by a variable distance d. 
       FIG. 14C  illustrates a 360° spinning mechanism implemented in the vertical conveyer drying system  100 , in accordance with an embodiment of the present disclosure. The spinner mechanism  150  can be used in conjunction with the clamping/hook mechanism for example shown in  FIGS. 14A-14B . In particular, the spinner mechanism  150  can be affixed to hook securing portions  173 ,  174  (i.e., clamp/hooks) via entry point  151 , with the hook portion  171  of  FIG. 14B  then attached to the connection points  158  along the track  157  shown in  FIG. 14A . Alternatively, the entry point  151  can be affixed or secured to a shaft  145  of clamping mechanism  141 , for example, as shown in  FIGS. 13A-B . The spinner mechanism  150  can be used to spin the flower or plant constantly 360° degrees while traveling through the drying chamber affixed to the track conveyor system  115 . The speed of the spinner mechanism  150  is further configurable in terms of velocity of spinning speed. Hence, the spinner mechanism  150  provides for an automated form of drying in a spinning fashion. 
     In certain disclosed embodiments, the VFC system  100  is implemented to optimize certain complex series of biosynthetic reactions that form precursors to natural cannabinoids, such as geranyl pyrophosphate and olivetolic acid, which are produced themselves by a complex series of biosynthetic reactions. Geranyl pyrophosphate and olivetolic acid bond to each other with the assistance of an enzyme in the prenyltransferase category known as GOT, thus creating the first cannabinoid, CBGA (with the molecular bond structure as illustrated in  FIG. 15 ). CBGA, or Cannabigerolic acid (CBGA), contains a carboxylic acid group (with the molecular formula COOH), and due to the presence of that acidic group, an “A” is placed at the end of CBGA. This is true for the rest of the cannabinoids whose acronyms end with the letter A (THCA, CBDA, etc.). The carboxylic acid groups spontaneously break off the cannabinoid structures as carbon dioxide (CO2) gas when heated, in certain disclosed embodiments of the VFC drying system  100 . This process that is effected by heating, is called decarboxylation, after which the “A” designation is lost. For example, decarboxylated CBGA becomes CBG. This is considered a degradation process because it does not require enzymes and occurs after the plant is harvested. The CBG type of cannabinoids have one ring in the molecular structure; it&#39;s the aromatic ring that is originated from the olivetolic acid. 
     In certain aspects or embodiments, CBGA is the first cannabinoid formed from a biosynthetic reaction that joined two smaller pieces together. CBGA is also the precursor to other natural phytocannabinoids. Next, CBGA is cyclized into THCA, CBDA, or CBCA via the enzymes known as THCA synthase, CBDA synthase, and CBCA synthase. The presence and relative quantities of the specific enzymes determine which cannabinoid is the major product from each particular strain and even, each particular cell. The CBG type cannabinoids have generally only one ring in their structure. After the cyclization reactions, the THCA, CBDA, and CBCA cannabinoids have multiple rings in their structures as shown in  FIG. 16 . 
     In certain aspects or embodiments, for THCA, two new rings are formed by the creation of two new covalent bonds, a carbon-oxygen (C—O) bond and a carbon-carbon (C—C) bond. The CBDA synthase enzyme catalyzes a reaction that creates one new C—C bond at the same position that the C—C bond formed in THCA, but without the new C—O bond, thus forming CBDA. The formation of CBCA occurs by the formation of one (C—O) bond at a different position of the molecule than the (C—O) bond formed in THCA. Hence, compounds with two rings fused to one another, such as in CBCA and CBC, are considered to be bi-cyclic. Thus, in certain aspects or embodiments, disclosed is the processes in which THCA, CBDA, and CBCA are made through biosynthesis during implementation of heat and/or drying conducted through the VFC drying system  100 . 
     In certain aspects or embodiments, when cannabis flower is dried and cured properly, the result is that in prominent cannabinoids, for example, are the acidic forms of the cannabinoids (THCA, CBDA, CBCA, or CBGA). When heated or dried, these molecules decarboxylate. While decarboxylated forms of cannabinoids might be produced to a small extent biosynthetically during drying, acidic forms are generally the product. The decarboxylation products generated are delta-9-THC, cannabidiol (CBD), and cannabichromene (CBC) (referring to  FIG. 16 ). 
     Hence, the VFC drying system  100  implements a drying/heating cycle that for certain flowers/plants, results in complex processes/developments of cannabinoids, flavonoids, and terpenes that can take place in the plant&#39;s glandular trichomes. 
     By way of background, cannabinoids, terpenes, and flavonoids are produced within the trichrome cells through biosynthesis, in which enzymes catalyze a series of chemical reactions to produce complex molecules from simple (smaller) molecules. Cannabinoids produced by the cannabis plant, or phytocannabinoids, interact with our body&#39;s receptors to produce numerous psychotropic and therapeutic effects that may be implemented in medical therapeutic uses, for example. Terpenes are compounds responsible for the aroma and flavors of cannabis, and support cannabinoids in producing desired effects. Flavonoids are similar to terpenes and contribute to a plant&#39;s aroma and flavor profile, but may offer their own unique therapeutic effects as well. 
     The three basic steps for cannabinoid biosynthesis are binding, prenylation, and cyclization. On a molecular level, nanoscale macromolecules called enzymes bind to one or two small molecules (substrates), attach the substrates to each other (prenylation, catalytic chemical conversion of the substrates), then pass the small molecule (transformed substrate) down to another enzyme that processes it, making sequential changes to the small molecule (cyclization). The enzymes act as biological nanomachines that use chemical energy rather than mechanical energy to build structures. Enzymes have inspired numerous studies in nanotechnology, biology, and other fields. 
     The VFC system  100  as shown in  FIG. 10 , begins the initial phase of an example RF and Microwave (MW) drying process with the track initiating the drying cycle at input  101 . The items, plants, flowers or other vegetation to be dried, enters the microwave/RF drying chamber  102  with the microwave drying phase first followed by the rest zone phase and finally the RF drying phase. Following these drying phases, an oil extraction process can then proceed. The dried plants/flowers are next placed in steel canisters for high pressure nitrogen/oxygen extraction process in which oil is extracted through tubes and next pressed. Biomass recovery process is also an option for recovery of stems, etc. and can be used in industry. Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals. The biomass can also be burned to create heat (direct), converted into electricity (direct), or processed into biofuel (indirect). Thermal Conversion also can be performed. The biomass can be burned by thermal conversion and used for energy. 
     Current uses for that extracted biomass are many. Among other things, biomass can be implemented to create: 1) Hemperete, i.e., concrete manufactured utilizing hemp, for products such as bricks or utilized in the same fashion as concrete; 2) Fiber board/hemp plywood utilized as a plywood substitute; 3) Fiber for a multitude of industrial uses—from construction to insulation; 4) Hemp seed oil; 5) Hemp paper (e.g., rolling papers); 5) De-hulled hemp seed/nut for food products; and/or 6) Seed for bird food, among other implementations. 
     In certain aspects or embodiments, other contemplated uses can included but are not limited to the following: 1) Cellulose: isolation for potential plastic manufacturing for cannabis packaging; 2) Hemp cardboard for cannabis packaging; 3) Lipids, fats and wax for salves, creams and lip balm; 4) Waste ethanol for potential re-distillation; 5) Fuel, including ethanol; 6) Soil amendment; and/or 7) Pet products for both wellness and/or as bedding. 
     Plants absorb the sun&#39;s energy through photosynthesis, and convert carbon dioxide and water into nutrients (carbohydrates). The energy from these organisms can be transformed into usable energy through direct and indirect means. Biomass can be burned to create heat (direct), converted into electricity (direct), or processed into biofuel (indirect). Thermal Conversion is yet another example. Biomass can be burned by thermal conversion and used for energy. Thermal conversion involves heating the biomass feedstock in order to burn, dehydrate, or stabilize it. The most familiar biomass feedstocks for thermal conversion are raw materials such as municipal solid waste (MSW) and scraps from paper or lumber mills. Different types of energy are created through direct firing, co-firing, pyrolysis, gasification, and anaerobic decomposition. Before biomass can be burned, however, it must be dried. This chemical process is called torrefaction. During torrefaction, biomass is heated to about 200° to 320° Celsius (390° to 610° Fahrenheit). This can be accomplished using one of the disclosed drying systems. 
     The biomass dries out so completely that it loses the ability to absorb moisture, or rot. It loses about 20% of its original mass, but retains 90% of its energy. The lost energy and mass can be used to fuel the torrefaction process. During torrefaction, biomass becomes a dry, blackened material. It is then compressed into briquettes. Biomass briquettes are very hydrophobic, meaning they repel water. This makes it possible to store them in moist areas. The briquettes have high energy density and are easy to burn during direct or co-firing. 
     Pyrolysis is a related method of heating biomass. During pyrolysis, biomass is heated to 200° to 300° C. (390° to 570° F.) without the presence of oxygen. This keeps it from combusting and causes the biomass to be chemically altered. Pyrolysis produces a dark liquid called pyrolysis oil, a synthetic gas called syngas, and a solid residue called biochar. All of these components can be used for energy. Pyrolysis oil, sometimes called bio-oil or biocrude, is a type of tar. It can be combusted to generate electricity and is also used as a component in other fuels and plastics. Scientists and engineers are studying pyrolysis oil as a possible alternative to petroleum. 
     Another process is the extraction of cannabidiol. Cannabidiol (CBD) is one of the chemical compounds or cannabinoids that is present in the cannabis plant. CBD is known for having a range of profound medical benefits that range from fighting chronic ailments, such as pain and anxiety, to promoting wellness through protecting brain health and aiding in weight loss. The way that this cannabinoid can do so much for our bodies is by interacting with our Endocannabinoid System. This is part of our central nervous system that is responsible for maintaining balance in the body. The majority of CBD is extracted from industrial hemp, which is a term used to describe strains of the cannabis plant that contains 0.3% or less of THC. THC is the psychoactive cannabinoid in the plant, which causes the high or euphoria associated with other methods of consumption. 
     CBD extraction is the method used to isolate CBD from the plant and separate it from the other cannabinoids present. There are a variety of ways this is done, some of which are considered better than others. The manner in which the CBD is extracted will impact the quality and purity of the final product, which is then used in a variety of different ways for consumers to reap the benefits. Some methods of extracting CBD can leave trace amounts of other cannabinoids or harmful residues that can compromise its effects, so it is essential to consider when one is searching for the best product for a particular need. Generally, the known ways that CBD is extracted is one of the following methods: 1) The Rick Simpson Method; 2) Carrier Oil Extraction; 3) Alcohol Extraction; and/or 4) CO 2  Extraction. 
     CO 2  Extraction is carbon dioxide extraction. This is the most widely-used and best method for extracting CBD. Because of its efficacy and purity, it is quickly becoming an industry standard. There are three types of this process, which are supercritical, subcritical and ‘mid-critical.’ Supercritical is the most widely used so, for the sake of simplicity, described hereinbelow as an example. In the simplest possible terms, CO 2  acts as a solvent when used at the proper temperature and pressure. However, it poses none of the dangers that come with using other solvents. That makes this method incredibly safe and effective for CBD extraction. Specialized equipment is used to convert the CO 2  into a liquid that is at supercritical cold temperatures. When the CO 2  is in this state, it is perfect for extracting the cannabinoids because it isn&#39;t going to cause any damage to the plant matter or compounds therein. The supercritical carbon dioxide is passed through the plant matter extracts all of the useful oils so that it can be further filtered and used. The resulting solution passes through a separator that draws out at all of the cannabinoids and terpenes and oftentimes, the CO 2  can be reused for this method. The ability to reuse it makes this an economically sound extraction method for companies who create CBD products on a large scale. 
     Subcritical and mid critical extraction is gentler and won&#39;t pull out some of the larger molecules that companies may not want to use. Either of these methods can be used to create full-spectrum CBD oils that contain other cannabinoids as well. Supercritical extraction is best for pure CBD products. These processes can be used once the plants/flowers/stems have been dried by the disclosed drying system  100 , for extraction of useful CBD which is emerging in the health field as having many proven health benefits and uses for treatments of a wide range of medical conditions.

The term “machine-readable medium” shall accordingly be taken to include, but not be limited to: solid-state memories such as a memory card or other package that houses one or more read-only (non-volatile) memories, random access memories, or other re-writable (volatile) memories; magneto-optical or optical medium such as a disk or tape; and/or a digital file attachment to e-mail or other self-contained information archive or set of archives is considered a distribution medium equivalent to a tangible storage medium. Accordingly, the embodiment is considered to include anyone or more of a tangible machine-readable medium or a tangible distribution medium, as listed herein and including art-recognized equivalents and successor media, in which the software implementations herein are stored. 
     Although the present specification describes components and functions implemented in the embodiments with reference to particular standards and protocols, the disclosed embodiment(s) are not limited to such standards and protocols. 
     The illustrations of embodiments described herein are intended to provide a general understanding of the structure of various embodiments, and they are not intended to serve as a complete description of all the elements and features of apparatus and systems that might make use of the structures described herein. Many other embodiments will be apparent to those of skill in the art upon reviewing the above description. Other embodiments may be utilized and derived there from, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. Figures are also merely representational and may not be drawn to scale. Certain proportions thereof may be exaggerated, while others may be minimized. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense. 
     Such embodiments of the inventive subject matter may be referred to herein, individually and/or collectively, by the term “embodiment” merely for convenience and without intending to voluntarily limit the scope of this application to any single embodiment or inventive concept if more than one is in fact disclosed. Thus, although specific embodiments have been illustrated and described herein, it should be appreciated that any arrangement calculated to achieve the same purpose may be substituted for the specific embodiments shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments. Combinations of the above embodiments, and other embodiments not specifically described herein, will be apparent to those of skill in the art upon reviewing the above description. 
     The Abstract is provided to comply with 37 C.F.R. § 1.72(b), which requires an abstract that will allow one upon review to quickly ascertain the nature of the technical disclosure. The Abstract generally permits one to determine quickly from a cursory inspection of thereof, the nature and gist of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter. 
     In a particular non-limiting, example embodiment, the computer-readable medium can include a solid-state memory such as a memory card or other package that houses one or more non-volatile read-only memories. Further, the computer-readable medium can be a random-access memory or other volatile re-writable memory. Additionally, the computer-readable medium can include a magneto-optical or optical medium, such as a disk or tapes or other storage device to capture carrier wave signals such as a signal communicated over a transmission medium. A digital file attachment to an e-mail or other self-contained information archive or set of archives may be considered a distribution medium that is equivalent to a tangible storage medium. Accordingly, the disclosure is considered to include any one or more of a computer-readable medium or a distribution medium and other equivalents and successor media, in which data or instructions may be stored. 
     In accordance with various embodiments, the methods, functions or logic described herein may be implemented as one or more software programs running on a computer processor. Dedicated hardware implementations including, but not limited to, application specific integrated circuits, programmable logic arrays and other hardware devices can likewise be constructed to implement the methods described herein. Furthermore, alternative software implementations including, but not limited to, distributed processing or component/object distributed processing, parallel processing, or virtual machine processing can also be constructed to implement the methods, functions or logic described herein. 
     It should also be noted that software which implements the disclosed methods, functions or logic may optionally be stored on a tangible storage medium, such as: a magnetic medium, such as a disk or tape; a magneto-optical or optical medium, such as a disk; or a solid state medium, such as a memory card or other package that houses one or more read-only (non-volatile) memories, random access memories, or other re-writable (volatile) memories. A digital file attachment to e-mail or other self-contained information archive or set of archives is considered a distribution medium equivalent to a tangible storage medium. Accordingly, the disclosure is considered to include a tangible storage medium or distribution medium as listed herein, and other equivalents and successor media, in which the software implementations herein may be stored. 
     Although specific example embodiments have been described, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader scope of the inventive subject matter described herein. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense. The accompanying drawings that form a part hereof, show by way of illustration, and not of limitation, specific embodiments in which the subject matter may be practiced. The embodiments illustrated are described in sufficient detail to enable those skilled in the art to practice the teachings disclosed herein. Other embodiments may be utilized and derived therefrom, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. This Detailed Description, therefore, is not to be taken in a limiting sense, and the scope of various embodiments is defined only by the appended claims, along with the full range of equivalents to which such claims are entitled. 
     Such embodiments of the inventive subject matter may be referred to herein, individually and/or collectively, by the term “embodiment” merely for convenience and without intending to voluntarily limit the scope of this application to any single embodiment or inventive concept if more than one is in fact disclosed. Thus, although specific embodiments have been illustrated and described herein, it should be appreciated that any arrangement calculated to achieve the same purpose may be substituted for the specific embodiments shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments. Combinations of the above embodiments, and other embodiments not specifically described herein, will be apparent to those of skill in the art upon reviewing the above description. 
     In the foregoing description of the embodiments, various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting that the claimed embodiments have more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate example embodiment. 
     Although preferred embodiments have been described herein with reference to the accompanying drawings, it is to be understood that the disclosure is not limited to those precise embodiments and that various other changes and modifications may be affected herein by one skilled in the art without departing from the scope or spirit of the embodiments, and that it is intended to claim all such changes and modifications that fall within the scope of this disclosure.
