Description:
BACKGROUND 
       [0001]    1. Field 
         [0002]    Embodiments of the invention relate to power systems for aerial devices. More particularly, embodiments of the invention relate to an isolated electronic backbone architecture for aerial devices. 
         [0003]    2. Related Art 
         [0004]    Utility workers utilize an aerial device to reach inaccessible locations. The aerial device generally includes a boom with a utility platform connected to a distal end of the boom. One or more utility workers stand in the utility platform to perform a task. Utility workers typically use an aerial device to access overhead electric power lines and electric power components for installation, repair, or maintenance. 
         [0005]    The utility platforms utilized by electric utility workers are highly insulated so as to prevent the discharge of electricity through the utility truck, and especially through the utility worker. However, these utility platforms require power to perform various functions and equipment. In order to maintain this insulation, aerial devices of the prior art utilize only hydraulic power or battery power at the utility platform. This presents several problems because hydraulic power is limited in what functions it can perform and is very inefficient, and battery power requires continual replacement and maintenance. 
         [0006]    Aerial devices of the prior art are also frequently inefficient. First, the hydraulic power systems of aerial devices are powered by large diesel or gas internal-combustion engines. These engines must operate continuously or nearly continuously during static operations to power the various functions. While some operators can turn the engine off when not necessary, the ratio of hydraulic operation to total engine running time is very inefficient. Similarly, the entire engine must be run even when only a small percentage of the total horsepower is necessary to perform the various functions. Second, there are significant energy losses in valves, manifolds, and lines. For example, pressure drop from a pump to an actuator can be as great as 400 psi in some system designs. 
       SUMMARY 
       [0007]    Embodiments of the invention solve the above-mentioned problems and provide a distinct advance in the art by providing an electronic backbone architecture that provides power on demand and provides electrical power throughout the aerial device. The electronic backbone architecture is a system of electrical components connected by an electrical line, all of which is electrically isolated from the aerial device. The electronic backbone architecture provides an electrical motor associated with a respective actuator. Power is provided to each electrical motor from a power source via a protected electrical line. Each electrical motor is only powered so long as the actuator is being utilized. This is different from the inefficient prior art in which a single, large hydraulic pump provides the power to all of the actuators and runs continuously or nearly continuously. As such, the excessive and unnecessary motor running is eliminated. The losses due to hydraulic lines and valves are also effectively reduced. Further, the excessive weight from hydraulic lines and fittings is reduced. 
         [0008]    A first embodiment of the invention is directed to an electronic backbone architecture configured to provide electrical power to an aerial device. The isolated electronic backbone architecture comprises: a power source for generating electrical power, a first actuator, a first electrical motor for powering the first actuator, a second actuator, a second electrical motor for powering the second actuator, and a protected electrical line. The first actuator is disposed adjacent to the first electrical motor. The second actuator is disposed adjacent to the second electrical motor. The protected electrical line is configured to carry electrical current between the power source, the first electrical motor, and the second electrical motor. 
         [0009]    A second embodiment of the invention is directed to an aerial device. The aerial device comprises a grounded base, an insulated utility platform assembly, and an isolated electronic backbone architecture. The insulated utility platform is disposed at a distal end of a boom assembly of the grounded base. The isolated electronic backbone architecture provides electrical power at the utility platform. The electronic backbone architecture comprises a power source and a protected electrical line. The protected electrical line traverses from the base to the utility platform. The protected electrical line provides electrical current at the utility platform and the grounded base while being isolated from both the insulated utility platform and the grounded base. 
         [0010]    A third embodiment of the invention is directed to an aerial device. The aerial device comprises a grounded base, an insulated utility platform assembly, and an isolated electronic backbone architecture. The insulated utility platform is disposed at a distal end of a boom assembly of the grounded base. The isolated electronic backbone architecture provides electrical power at the utility platform. The electronic backbone architecture comprises a power source and a protected electrical line. The protected electrical line traverses from the base to the utility platform. The protected electrical line provides electrical current at the utility platform and the grounded base while being isolated from both the insulated utility platform and the grounded base. 
         [0011]    Additional embodiments of the invention may be directed to a method of providing power to an aerial device, a method of insulating an aerial device, a method of providing electrical power at a utility platform, etc. Embodiments of the invention may also be directed to electrical motors configured for use with an electronic backbone architecture for an aerial device, actuators configured for use with an electronic backbone architecture, protected electrical lines configured for use with an electronic backbone architecture, etc.

       DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0021]    The following detailed description of the invention references the accompanying drawings that illustrate specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled. 
         [0022]    In this description, references to “one embodiment”, “an embodiment”, “embodiments”, “various embodiments”, “certain embodiments”, “some embodiments”, or “other embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment”, “an embodiment”, “embodiments”, “various embodiments”, “certain embodiments”, “some embodiments”, or “other embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the technology can include a variety of combinations and/or integrations of the embodiments described herein. 
         [0023]    Turning now to the figures, and specifically  FIG. 1 , a schematic diagram of an aerial device  10  is provided. The aerial device  10  comprises a grounded base  12 , an insulated utility platform  14 , and an electronic backbone architecture  16 . As discussed below, each of the grounded base  12 , insulated utility platform  14 , and the electronic backbone architecture  16  is electrically isolated from one another, as can be seen in  FIG. 2 . The grounded base  12  is in contact with the ground and formed at least in part of metal, such that electrical current could flow therethrough and discharge. The insulated utility platform  14  is formed at least in part of a polymer, such that electrical current is prevented from discharging to the grounded base  12 . The electronic backbone architecture  16  provides power and mechanical movements to move the various components of the aerial device  10  as desired. The electronic backbone architecture  16  is formed at least in part of metal, such that electrical current can flow therethrough. However, the electronic backbone architecture  16  is electrically isolated from both the grounded base  12  and the insulated utility platform  14 , such that any external application of current thereto would not be able to discharge through the grounded base  12 . This allows the electronic backbone architecture to safely operate even within the insulated utility platform  14  in an environment in which contact with an electrified external source (such as a power line) is likely. 
         [0024]    The electronic backbone architecture  16  runs throughout the grounded base  12  and the insulated utility platform  14  to provide electrical power to various electrical motors  18 , which in turn operate various actuators  20 . The actuators  20  may include linear actuators  22  (that selectively elongate to achieve the desired motion of the component, as illustrated in  FIG. 3 ) and rotary actuators  24  (that selectively rotate or pivot to achieve the desired motion of the component, as illustrated in  FIG. 4 ). It should be appreciated that the electronic backbone architecture  16  is electrically isolated from both the grounded base  12  and the insulated utility platform assembly  14 . In this way, a single failure of the insulation will not allow an undesirable and dangerous discharge of electricity through the grounded base  12 . Each of the electrical motors  18  is located substantially adjacent to the associated actuator  20 . The electrical motor runs only so long as is necessary to provide power to the actuator. This provides a highly efficient operation in moving the boom because only the necessary electrical motors are running at any given time. 
         [0025]    Reference herein to “isolated,” “electrically isolated,” “insulated,” “electrically insulated,” or similar phraseology should be understood to mean prevention of the discharge or flow of electrical charge. These terms can refer to dielectric materials that have a high resistivity (such as a polymer or ceramic), physical separation (such that air is the insulator), or the like. The degree to which the various components are isolated may meet or exceed certain Occupational Safety and Health Administration (OSHA) regulations or other applicable safety regulations. 
         [0026]    The grounded base  12  generally includes a chassis  26 , a cab  28 , and a boom assembly  30 . The boom assembly  30  is rotatably mounted onto the chassis  26 . The grounded base  12  of the aerial device  10  is a selectively stabilized platform. In embodiments of the invention, the base  12  is a utility truck (as illustrated in  FIG. 1 ), a crane base, an oilrig, an earth-working machine, or a fixed structure. The base  12  provides stability and a counterweight to a load being supported by the boom assembly  30 . The base  12  may be specifically grounded (e.g., via a grounding cable or the like) or it may be incidentally near enough to the ground to be considered grounded. 
         [0027]    The base  12  typically is in contact with the ground via a set of tires  32 , a set of front outriggers  34 , and/or a set of rear outriggers  36 . It should be appreciated that outriggers are typically formed of metal and as such are electrically conductive. The outriggers may fully or partially raise the tires  32  off the ground. The base  12  may also include a mobile operations motor that propels the grounded base  12  along the ground between work sites. The mobile operations motor is typically an internal combustion engine, but could be an electrical engine. The mobile operations engine is typically electrically isolated from the electronic backbone architecture  16 . This is because the mobile operations engine is typically not in use while static operations are being performed. The mobile operations engine is in contact with the grounded base  12 . 
         [0028]    The base  12  includes various components of the electronic backbone architecture  16 . In embodiments of the invention, the base  12  comprises a power source  38 , a front outrigger assembly  40 , and a rear outrigger assembly  42 . The power source  38  generates the electrical power that will be utilized by the various electrical motors  18  discussed below. The power source  38  may additionally, or in the alternative, include a battery or other charge-storing component. It should be appreciated that, like other components of the electronic backbone architecture  16  described below, the power source  38  is electrically isolated from the other components of the grounded base  12 . In this way, if during an accident a component of the electronic backbone architecture  16  becomes electrically stimulated, the power source  38  will not allow for a discharge of the electricity that could cause serious damage and potential injury to the utility worker. This is because the power source is surrounded by an insulating material such that an electrical charging of the power source  38  (such as by a component of the electronic backbone architecture  16  coming into contact with an external electrical power line) is prevented. 
         [0029]    The front outrigger assembly  40  and the rear outrigger assembly  42  each comprises an electrical motor  18  and at least one actuator  20 . Upon receipt of a command to deploy, the electrical motor  18  associated with the actuators  20  pushes or otherwise deploys the front outrigger assembly  40  and the rear outrigger assembly  42 . Typically, the front outrigger assembly  40  and the rear outrigger assembly  42  will deploy simultaneously. However, in some instances, the utility worker may decide to deploy them independently (such as to ensure that either is properly set before attempting to deploy the other). It should be appreciated that the front outrigger assembly  40  comprises a left outrigger and a right outrigger. Similarly, the rear outrigger assembly  42  comprises a left outrigger and a right outrigger. Therefore, in embodiments of the invention, the front outrigger assembly  40  and the rear outrigger assembly  42  may include a single electric motor  18 , a left actuator, and a right actuator. 
         [0030]    In embodiments of the invention, the boom assembly  30  comprises a pivoting boom section  44 , an outer boom section  46 , and an inner boom section  48 . The pivoting boom section  44  is secured to a boom turret  50  on the chassis  26 . The boom assembly  30  pivots and/or rotates via various electrical motors  18  and actuators  20 , as discussed below. The various components of the boom assembly  30  work together in order to place the utility platform assembly  14  (or other implement) in a desired position relative to the ground and any other object (such as a utility pole) such that the utility worker can perform the desired task. Typically, the grounded base  12  is stationary and secured (such as via the outriggers) while the boom assembly  30  is in operation. 
         [0031]    The pivoting boom section  44  pivots upward and downward relative to the boom turret  50 . The pivoting boom section  44  does not telescope out of any other boom section. Instead the pivoting boom section  44  rotates about the base  12  at the boom turret  50 , and the outer boom section  46  pivots and/or rotates relative to the pivoting boom section  44 . The use of the pivoting boom section  44  allows the utility platform  14  to reach certain areas and avoid obstacles in the working environment. The pivoting boom section  44  is typically formed of metal for structural stability. 
         [0032]    In embodiments of the invention, a turret rotation assembly  52  is associated with the pivoting boom section  44  and the boom turret  50 . A turret rotation motor  54  powers a turret rotation actuator  56 . The turret rotation motor  54  receives electrical current from the power source  38 . The turret rotation motor  54  powers the turret rotation actuator  56  that rotates the boom assembly  30  about a substantially vertical axis. The turret rotation motor  54  may also receive instructions indicative of movement in a certain direction at a certain speed, a desired total angle change, a desired direction, the speed of angle change, an ending angle, etc. The boom rotation motor may then power the turret rotation actuator  56  to achieve the desired angle. It should be appreciated that in some embodiments of the invention, the boom rotation motor is only engaged so long as the boom rotation actuator is being moved. In this way, excessive losses and idling from traditional configurations are avoided. 
         [0033]    Similarly, embodiments of the invention include a turret pivot assembly  68  associated with the pivoting boom section  44  and the boom turret  50 . A turret pivot actuator  60  is powered by a turret pivot motor  62  (which may be the same as, or distinct from, the turret rotation motor  54 ). The turret pivot motor  62  receives electrical current from the power source  38 . The turret pivot motor  62  powers the turret pivot actuator  60  to pivot the boom assembly  30  upward and downward between substantially horizontal and substantially vertical). The boom pivot motor may power the turret pivot actuator  60  to achieve the desired vertical angle (i.e., angle above a horizontal plane). The turret pivot actuator  60  may be a linear actuator  22  (such as illustrated in  FIG. 3  and discussed below) or a rotary actuator  24  (such as illustrated in  FIG. 4  and discussed below). 
         [0034]    The outer boom section  46  is a hollow, elongated member that presents a proximal end  64  and a distal end  66 . The outer boom section  46  is rotatably and/or pivotably coupled to the pivoting boom section  44  at the proximal end  64  of the outer boom section  46 . The outer boom section  46  is typically formed of a metal for structural stability, but could instead be formed of an electrically-resistant polymer, such as fiberglass or another material. 
         [0035]    Embodiments of the invention include an outer-boom pivot assembly  68  associated with the pivoting boom section  44  and the outer boom section  46 . An outer-boom pivot actuator  70  is disposed on the pivoting boom section  44  to push the outer boom section  46  to a specific angle relative to the pivoting boom section  44 . The outer-boom pivot actuator  70  is powered by an outer-boom pivot motor  72 . The outer-boom pivot motor  72  receives electrical current from the power source  38 . The outer-boom pivot motor  72  powers the outer-boom pivot actuator  70  to pivot the outer boom section  46  upward and downward. The outer-boom pivot motor  72  may power the outer-boom pivot actuator  70  to achieve the desired vertical angle (i.e., angle above a horizontal plane). 
         [0036]    The inner boom section  48  is at least partially disposed within the distal end  66  of the outer boom section  46  and telescopes to extend or retract relative to the first boom section. The inner boom section  48  is an elongated member that presents a proximal end  74  and a distal end  76 . The inner boom section  48  is formed of an electrically-resistant polymer, such as fiberglass or another material. The proximal end  74  of the inner boom section  48  is disposed within the outer boom section  46 . The distal end  76  of the inner boom section  48  is secured to the utility platform  14 . 
         [0037]    The inner boom section  48  is elongated and retracted within the outer boom section  46  via a boom elongation assembly  78 . A boom elongation actuator  80  pushes or pulls the inner boom to achieve a desired length of the boom assembly  30 . The boom elongation actuator  80  is powered by a boom elongation motor  82 . The boom elongation motor  82  receives electrical current from the power source  38 . The boom elongation motor  82  powers the boom elongation actuator  80  to elongate the boom assembly  30  or retract the boom assembly  30 , as desired. 
         [0038]    For purposes of this disclosure, the outer boom section  46  and the pivoting boom section  44  are considered components of the grounded base  12 , and the inner boom section  48  is considered a component of the insulated utility platform assembly  14 . This is best illustrated in  FIG. 2 . This is because, as discussed above, the base  12 , the outer boom section  46 , and the pivoting boom section  44  are all typically formed of a metal and are in contact with the grounded base  12  (such that an application of electrical current to the outer boom section  46  and/or the pivoting boom section  44  will discharge through the grounded base  12 ). Alternatively, the inner boom section  48  is isolated from the grounded base  12  via the insulative properties of the polymer (or other material) from which it is formed. In other embodiments of the invention, the entirety of the boom assembly  30  is formed of a polymer. In these embodiments, the entirety of the boom assembly  30  may be considered a component of the utility platform assembly  14 . In either case, each of the three distinct components of the aerial device  10  (the grounded base  12 , the utility platform  14 , and the electronic backbone architecture  16 ) is electrically distinct and isolated from the others. 
         [0039]    In other embodiments of the invention, the boom assembly  30  comprises a single boom section (not illustrated). In still other embodiments of the invention, the boom assembly  30  comprises the pivoting boom section  44 , the outer boom section  46 , a first inner boom section, and a second inner boom section that telescopes within the first inner boom section (not illustrated). The first inner boom section may be formed of a polymer as well, so as to increase the range of the insulated utility platform assembly  14 . 
         [0040]    The boom assembly  30  is extended, retracted, rotated, and pivoted via a set of lower boom controls  84 . The set of lower boom controls  84  is disposed on or near the base  12 . In embodiments of the invention, the set of lower boom controls  84  is disposed externally to the aerial device  10 , such that an operator stands on the ground or an exterior platform to manipulate the set of lower boom controls  84 . In other embodiments, the set of lower boom controls  84  is located in a cab  28  of the aerial device  10 , such that the operator sits or stands in the cab  28  to manipulate the set of lower boom controls  84 . 
         [0041]    The set of lower boom controls  84  sends commands and/or power to the various electric motors  18 , which in turn power various actuators  20  to manipulate the boom assembly  30  or utility platform  14  to move in a desired direction. In embodiments of the invention, the set of lower boom controls  84  comprises a joystick (not illustrated) in which the movement of the joystick is translated into electrical motor  18  operations with the assistance of a power source  38 , inputs into a computer which directs the electrical motor  18  operations, or any combination thereof. 
         [0042]    The insulated utility platform assembly  14  is disposed on the boom assembly  30  to provide an elevated platform for the accomplishment of a task by a utility worker. The insulated utility platform  14  generally includes the inner boom section  48  and a utility platform  14  (both formed of a polymer). The utility platform  14  is a bucket or other platform that couples to the distal end of the inner boom section  48 . In embodiments of the invention, the utility platform  14  comprises four bucket sidewalls and a bucket floor that form a cavity and present an interior segment and an exterior segment. The operator stands in the cavity to perform work. The platform may further comprise a bucket lip. There may be enough space within the platform for the operator to walk around, as well as store tools or supplies. The utility platform  14  may further comprise a door in at least one of the bucket sidewalls to allow for ingress and egress of the operator. In other embodiments of the invention, the utility platform  14  is a basket that comprises a handrail and a kick plate (not illustrated). 
         [0043]    The four bucket sidewalls of the utility platform  14  may be successively coupled to one another to form the interior segment with a horizontal cross-section that is substantially rectangular. Thus, two of the opposing bucket sidewalls may have a greater width than the other two opposing bucket sidewalls. In other embodiments, the four bucket sidewalls may form the interior segment with a horizontal cross-section that is substantially square. The bucket floor is coupled to at least one of the four bucket sidewalls. In embodiments of the invention, the bucket lip is coupled to at least one of the four bucket sidewalls. Although the dimensions of the platform may vary widely, an exemplary platform for one operator has a horizontal cross-section of approximately 24 inches by approximately 30 inches and has a height of approximately 42 inches. An exemplary platform for two operators has a horizontal cross-section of approximately 24 inches by approximately inches and has a height of approximately 42 inches. 
         [0044]    A set of upper boom controls  86  allows the operator to move the boom assembly  30  from within the utility platform  14 . The operator in the bucket has a better vantage point to know where and how to position the boom assembly  30  as opposed to the operator on the ground. Additionally, the set of upper boom controls  86  promotes efficiency by allowing the operator to directly control the movement of the boom assembly  30 . In embodiments of the invention, an assistant operator (not illustrated) can access the lower boom controls  84  for the duration of the operator being in the utility platform  14 . This provides a safety backup to allow the assistant operator to remove the operator from a dangerous situation should the operator become incapacitated or there be a failure in the set of upper boom controls  86 . The set of upper boom controls  86  may utilize the same or a different mechanism from the set of lower boom controls  84 . 
         [0045]    The set of upper boom controls  86  comprises a dash cover and at least one input (not illustrated). In various embodiments of the invention, the input can be a valve handle, a joystick, a button, a switch, or a combination thereof. The dash cover is generally flat or arcuate and presents at least one opening. Each of the at least one opening is situated around each of the at least one input. The dash cover may additionally contain written instructions and safety information. 
         [0046]    In embodiments of the invention, the utility platform  14  remains substantially level regardless of the position of the boom assembly  30  via a platform leveling assembly  88 . The utility platform  14  is leveled by a platform leveling assembly. The platform leveling assembly keeps the floor of the utility platform  14  substantially parallel to the ground. This is important especially during movement of the boom assembly  30  with the utility worker disposed in the utility platform  14 . Sudden changes in the relative angles of the utility platform  14  can be dangerous for the utility worker. In other embodiments, the operator manipulates a set of upper controls, discussed below, to manipulate the utility platform  14  into the flat position. The platform leveling assembly comprises a platform leveling motor  90  that powers at least one platform leveling actuator  92 . The platform leveling motor  90  either detects or acquires an indication of the angle of the utility platform  14  with respect to a hypothetical horizontal plane. The platform leveling motor  90  then automatically moves the utility platform  14  to keep the utility platform  14  level, especially during movement of the utility platform  14 . 
         [0047]    In embodiments of the invention, the implement can be maneuvered relative to the inner boom section  48  via a platform control assembly  94 . The platform control assembly  94  comprises at least one platform control actuator  96  and at least one platform control motor  98 . The platform control assembly  94  allows the utility worker to position the utility platform  14  in a desired orientation relative to the inner boom assembly  30 . This allows the utility worker to reach a desired position so as to complete the task. This may allow the utility platform  14  to pivot about the end of the inner boom section  48 , extend or retract, etc. 
         [0048]    In embodiments of the invention, a jib, winch, or other implement is powered by an implement control assembly  100  disposed in or near the utility platform assembly  14 . The implement assists the utility worker with performing the various tasks. For example, the jib may allow the utility worker to move an orient an object such as a repair part. As another example, the winch may allow the utility worker to lift a heavy object. The implement could also provide power for various external tools that could be utilized by the utility worker. The implement may comprise an implement actuator  102  and an implement motor  104 . 
         [0049]      FIG. 3  depicts a schematic diagram of an exemplary linear actuator  22  and associated electric motor  18 . The linear actuator  22  elongates a component of the aerial device  10 . This elongation may make the elongating component longer or may pivot the elongating component relative to another component. For example, the turret pivot actuator  70  may elongate so as to push or pull the pivoting boom segment relative to the boom turret  50 . The elongating component could be any of the above-discussed actuators  20  or other components of the aerial device  10 . 
         [0050]    As seen in  FIG. 3 , the electronic motor  18  and associated linear actuator  22  comprises a cable  106 , a motor controller  108 , the electric motor  18 , a pump  110 , a reservoir  112 , a diaphragm  114 , a manifold  116 , and a hydraulic cylinder  118 . The electronic motor  18  and associated linear actuator  22  operate as a standard hydraulic cylinder. The cable brings power and/or commands to the motor controller. The motor controller powers the motor  18  so as to the power the actuators  20 . 
         [0051]      FIG. 4  depicts a schematic diagram of an exemplary rotary actuator  24  and associated electric motor  18 . The rotary actuator  24  rotates or pivots a component of the aerial device  10 . This rotation or pivoting changes the position of the pivoting/rotating component relative to another component of the aerial device  10 . For example, the turret pivot actuator  70  may elongate so as to push or pull the pivoting boom segment relative to the boom turret  50 . 
         [0052]    As seen in  FIG. 4 , the electronic motor  18  and associated linear actuator  22  comprises the power cable, the motor controller, the electric motor  18 , a gearbox  120 , and an output shaft  122 . The gearbox provides rotation that is appropriate for the amount of power provided and can shift to another gear to assist in the rotation. The output shaft is secured to, or otherwise associated with, the component that is intended to be moved. 
         [0053]      FIG. 5  depicts a schematic of the utility platform  14 , illustrating how the components of the electronic backbone architecture  16  (specifically, the platform leveling assembly  88 , the platform control assembly  94 , and the implement control assembly  100 ) are brought into the utility platform  14 , while preventing a dangerous discharge of electricity. The discharge is prevented by shielding the electrical components, such as the cable  106 . The cable  106  may be embedded in the inner boom section  48  and the utility platform  14 , such as by laying the cable  106  into the fiberglass or other polymer of the inner boom section  48  and the utility platform  14  during construction. This provides further insulation and prevents damage to the cable. The electrical components of the electronic backbone architecture  16  are also not grounded such that any incidental contact with an electrified source would not allow for a discharge. In this way, the electronic backbone architecture  16  is safe to use even around electrical lines and the like. 
         [0054]      FIG. 6  depicts an exemplary electrical cable for carrying the current associated with the electronic backbone architecture  16  throughout the aerial device  10 . As discussed above, the electrical cable of the electronic backbone architecture  16  keeps the electronic backbone architecture  16  electrically isolated from both the grounded base  12  and the insulated utility platform assembly  14 . The cable includes various layers to allow the cable to be disposed adjacent to very high power electrical lines and the like without receiving interference, discharging that electrical current, or the like. The cable includes metallic current-carrying wires  124 , an inner protective casing layer  126 , a high-voltage insulation layer  128 , a magnetic field shielding layer  130 , an electric field shielding layer  132 , and an outer protective casing layer  134 . 
         [0055]    In embodiments of the invention, potential energy from lowering the boom assembly  30  (or other component) can be recouped. The recouped energy is accumulated in an energy storage device momentarily. The recouped energy can then used for future machine operations. This is advantageous over prior art aerial devices in which such energy was lost to heat and friction. 
         [0056]    While it has been discussed throughout, the steps of a method for performing a job or task while utilizing an aerial device  10  powered by an electronic backbone architecture  16  will now be discussed. The operator operates the set of upper boom controls  86  (which instruct the various electric motors  18  to activate and move their associated actuators  20  as desired) to position the utility platform  14  from a starting position adjacent to the ground into an elevated, desired location or orientation. The operator then performs a job or task while standing in the utility platform  14 . The job or task could include, but is not limited to, installing equipment, repairing equipment, uninstalling equipment, testing equipment, clearing a power line, maintaining trees and other vegetation, installing utility poles, moving a load, rescuing a stranded person, extinguishing a fire, recording a video, taking a photograph, and observing or supervising a task or job performed by others. The utility worker may then perform additional jobs or tasks, which may include moving the utility platform  14  into a different location or orientation, using the set of upper boom controls  86  to instruct the various electric motors  18  to power their associated actuators  20 . Upon the completion of all tasks or jobs, the utility worker returns the utility platform  14  to the position adjacent to the ground via the set of upper boom controls  86 . It should also be noted that the assistant operator at the set of lower boom controls  84  could perform some or all of the movement of the utility platform  14 .
