[0016] The following is a more detailed description of various concepts and specific implementations related to methods, apparatuses, and systems for drive unit assemblies. The various concepts introduced above and discussed in more detail below can be implemented in any of a variety of ways.

[0017] This disclosure relates to systems and methods for one or more components of a vehicle. These components may include at least one drive unit assembly. For example, these components may include a stator. The stator may include one or more conductors. For example, the stator may include conductors that provide electrical power. The stator may include or provide a three-phase electrical system. For example, the stator may include conductors associated with one or more phases.

[0018] The stator may include one or more slots. For example, the stator may include a first slot and a second slot. The slots may receive one or more conductors. For example, the first slot may receive a first number of conductors, and the second slot may receive a second number of conductors. These conductors may be associated with one or more phases. For example, the first number of conductors may be associated with a first phase, and the second number of conductors may be associated with a second phase.

[0019] The conductors may be positioned or located across or within the stator based on one or more patterns. For example, the first slot of the stator may receive conductors associated with a first phase. Continuing with this example, a second slot of the stator may be positioned adjacent a first side of the first slot, and a third slot of the stator may be positioned adjacent a second side of the first slot. The second slot may be associated with the first phase, the second phase, or the third phase. The third slot may be associated with the first phase, the second phase, or the third phase. The placement of the conductors according to the phases may include at least one pattern. The conductors may also include a staggered pattern and / or an alternating pattern. For example, the first slot may receive a first number of conductors. Continuing with this example, the second slot may receive a first subset of the first number of conductors, and the second slot may receive a second subset of the first number of conductors.

[0020] Layers or openings within the stator slots may affect or limit the number of conductor turns. For example, a stator having an even number of layers (e.g., a single slot receiving an even number of conductors) may affect the number of turns of the even number of conductors across the stator. The number of turns per phase may affect or define one or more relationships. For example, the turns per phase may affect the torque-speed envelope.

[0021] Some aspects of the present disclosure include providing a stator that includes conductors having a winding design. The winding design may enable transposing the conductors to similar layers within one or more slots of the stator. For example, a first conductor may be located or positioned within a first layer of a first slot. Continuing with this example, the first conductor may also be located or positioned within a second layer of a second slot. The assembly or design of the conductors creates a spacing or space between the respective conductors within a given slot, which enables transposing the conductors to the same layer within multiple slots.

[0022] The winding design described herein may provide increased flexibility regarding the number of turns of the conductors or provide configuration alternatives. For example, based on the winding design described herein, evenly transposing the conductors such that subsequent conductors are transposed across one or more slots of the stator creates or provides additional space. Since the number of turns of the conductors may define the torque-speed curve, an improvement in the configuration may enhance the torque-speed curve associated with the motor. Enhancement of the torque-speed curve may improve the overall performance of the motor or a vehicle including the motor.

[0023] Figure 1Depicts an exemplary cross - sectional view 100 of an electric vehicle 105 equipped with at least one battery pack 110. The electric vehicle 105 can include an electric truck, an electric sport utility vehicle (SUV), an electric van, an electric car, an electric vehicle, an electric motorcycle, an electric scooter, an electric passenger car, an electric passenger or commercial truck, a hybrid vehicle or other vehicles, such as marine or air vehicles, airplanes, helicopters, submarines, ships or drones, and other possibilities. The battery pack 110 can also be used as an energy storage system to power a building (such as a residential or commercial building). The electric vehicle 105 can be fully electric or partially electric (e.g., plug - in hybrid), and further, the electric vehicle 105 can be fully autonomous, partially autonomous or driverless. The electric vehicle 105 can also be manually operated or non - autonomous. An electric vehicle 105 such as an electric truck or car can include an on - board battery pack 110, a battery 115 or battery module 115, or battery cells 120 to power the electric vehicle. The electric vehicle 105 can include a chassis 125 (e.g., a frame, an internal frame or a support structure). The chassis 125 can support various components of the electric vehicle 105. The chassis 125 can span across the front portion 130 (e.g., the hood or cover portion) of the electric vehicle 105, the body portion 135 and the rear portion 140 (e.g., the trunk, payload or rear cargo portion). The battery pack 110 can be installed or placed within the electric vehicle 105. For example, the battery pack 110 can be installed within one or more of the front portion 130, the body portion 135 or the rear portion 140 on the chassis 125 of the electric vehicle 105. The battery pack 110 can include or be connected to at least one bus bar, e.g., a current collector element. For example, the first bus bar 145 and the second bus bar 150 can contain conductive materials to connect or otherwise electrically couple the battery 115, battery module 115 or battery cells 120 to other electronic components of the electric vehicle 105, thereby powering various systems or components of the electric vehicle 105.

[0024] The battery pack 110 can supply power to the electric vehicle 105. The battery pack 110 can include any arrangement or network of electrical, electronic, mechanical, or electromechanical devices to power any type of vehicle, such as the electric vehicle 105. The battery pack 110 can include at least one housing. The housing can include at least one battery module 115 or at least one battery cell 120, as well as other battery pack components. The battery module 115 can be or can include one or more sets of prismatic batteries, cylindrical batteries, pouch cells, or battery cells 120 of other form factors. The housing can include a shield on or below the bottom of the battery module 115 to protect the battery module 115 and / or the battery cell 120 from external conditions, for example, in the case where the electric vehicle 105 is traveling on rough terrain (e.g., off-road sites, ditches, rocks, etc.). The battery pack 110 can include at least one cooling line that can distribute fluid through the battery pack 110 as part of a thermal / temperature control or heat exchange system that can also include at least one thermal component (e.g., a cold plate). The thermal component can be positioned relative to a top sub-module and a bottom sub-module, such as between the top sub-module and the bottom sub-module, and other possibilities. The battery pack 110 can include any number of thermal components. For example, each battery pack 110 or each battery module 115 can have one or more thermal components. At least one cooling line can be coupled, partially coupled, or independent of the thermal component.

[0025] Each of the battery modules 115 can include a plurality of battery cells 120. The battery modules 115 can be disposed within the housing of the battery pack 110. For example, the battery module 115 can include battery cells 120 that are cylindrical cells or prismatic cells. The battery module 115 can operate as a modular unit of the battery cells 120. For example, the battery module 115 can collect current or power from the battery cells 120 included in the battery module 115 and can provide the current or power as an output of the battery pack 110. The battery pack 110 can include any number of battery modules 115. For example, the battery pack can have one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, or other number of battery modules 115 disposed within the housing.

[0026] The battery module 115 can be square, rectangular, circular, triangular, symmetric, or asymmetric. In some examples, the battery modules 115 can be of different shapes such that some battery modules 115 are rectangular while other battery modules 115 are square, and other possibilities. The battery module 115 can include or define a plurality of slots, holders, or containers for the plurality of battery cells 120. It should be noted that the illustrations and descriptions herein are provided for example purposes and should not be construed as limiting.

[0027] The battery cell 120 may be included in the battery module 115 of the battery pack 110 to power components of the electric vehicle 105. A housing may be provided in the battery module 115, the battery pack 110, or a battery array installed in the electric vehicle 105. The battery cell housing may be of any shape, such as cylindrical with a circular, oval, or egg-shaped base, etc. The shape of the housing may also be prismatic with a polygonal base. The housing may include a pouch form factor. The housing may include other form factors, such as triangular, square, rectangular, pentagonal, and hexagonal, etc. In some embodiments, the battery pack may not include modules (e.g., module-less). For example, the battery pack may have a module-less or cell-battery pack configuration, in which the battery cells are arranged directly in the battery pack without being assembled into modules.

[0028] The current collector material (e.g., the current collector foil to which the electrode active material is laminated to form the cathode layer or the anode layer) may include a metallic material. For example, the current collector material may include aluminum, copper, nickel, titanium, stainless steel, or a carbon-containing material. The current collector material may be formed as a metal foil. For example, the current collector material may be aluminum (Al) or copper (Cu) foil. The current collector material may be a metal alloy made of Al, Cu, Ni, Fe, Ti, or a combination thereof. The current collector material may be a metal foil coated with a carbon material, such as carbon-coated aluminum foil, carbon-coated copper foil, or another carbon-coated foil material.

[0029] Figure 2 A perspective view of the motor 200 is depicted. The motor 200 may be coupled to a vehicle. For example, the motor 200 may be coupled to the vehicle 105. The motor 200 may be included in the vehicle 105. For example, the motor 200 may be disposed within the vehicle 105. The motor 200 may be provided as one or more components of the vehicle 105. For example, the motor 200 may be disposed within the vehicle 105 after the vehicle 105 is assembled. The motor 200 may include one or more electronic components. For example, the motor 200 may include components that may be coupled to a power source (e.g., the battery 115). The motor may include at least one stator 205. The stator 205 may be included in or provided as a drive unit assembly. The stator 205 may be electrically coupled to one or more components. For example, the stator may be electrically coupled to an inverter. Alternatively, the stator 205 may be electrically coupled to the battery 115.

[0030] The stator 205 may include at least one slot 220. The slot 220 may include or define at least one cavity. The slot 220 may receive or accommodate at least one conductor 210. The conductor 210 may include the conductors described herein. The stator 205 may include one or more slots 220 associated with one or more phases. For example, the stator 205 may include a first slot 220 and a second slot 220. Continuing with this example, the first slot 220 may be associated with a first phase, and the second slot 220 may also be associated with the first phase. The slot 220 may be associated with one or more phases based on the placement of a given slot 220 within the stator 205. The slot 220 may be associated with one or more phases in response to a given slot 220 receiving or accommodating one or more conductors 210 associated with a given phase.

[0031] The slot 220 may include a different number or quantity of conductors. For example, the first slot 220 may receive a first quantity of conductors 210. Continuing with this example, the first quantity of conductors 210 may be associated with a first phase. The number or quantity of conductors may include different amounts. For example, the slot 220 may include one or more layers 255, and the layers 255 may define openings or spaces to receive one or more conductors 210. The slot 220 may receive one or more subsets of the conductors 210. For example, the first slot 220 may include a first subset of the conductors 210 and a second subset of the conductors 210. Continuing with this example, the first subset of the conductors 210 may also be included in the second slot 220, and the second subset of the conductors 210 may also be included in the third slot 220.

[0032] The slot 220 may receive a total odd number of conductors 210. For example, the first slot 220 may receive an odd number of conductors 210 associated with a given phase. As another example, the second slot 220 may receive a subset of an odd number of conductors 210 associated with a given phase. Continuing with this example, the second slot 220 may also receive a subset of the conductors 210 included in the third slot 220. As a non-limiting example, the first slot 220 may accommodate five conductors 210 or provide space for the five conductors (e.g., the first slot 220 includes five layers 255). Continuing with this non-limiting example, the first slot 220 may receive five conductors 210 (e.g., an odd number of conductors). In this non-limiting example, the first slot 220 may be associated with a single given phase in response to the five conductors 210 being associated with the single given phase.

[0033] The layers 255 may include various placement, arrangement, or positioning manners. For example, as Figure 2 shown, the slot 220 is shown as having five layers 255, where each layer 255 corresponds to a given conductor 210. The layer 255 closest to the center point of the stator 205 (e.g., the center of the pore or opening) may be regarded as the first layer or the front layer. The numbering of the layers 255 may follow one or more patterns.

[0034] Figure 2 Provide an example of conductor 210 associated with a single given phase. For example, conductor 210 may be associated with the first phase. As Figure 2 shown, the conductors 210 associated with the first phase may be grouped or bundled in sets of three slots 220. For example, three adjacent slots 220 may receive the conductors 210 associated with the first phase. As Figure 2 shown, each bundled slot 220 may receive an odd number of conductors 210. The bundled slots 220 may receive a subset of the conductors 210 from one or more subsequent slots 220.

[0035] Figure 3 is a top perspective view of the motor 200. As Figure 3 shown, the top perspective view includes a magnified view of the conductors 210. The conductors 210 may travel, extend, or otherwise be transposed along or across one or more directions. For example, the conductors 210 may leave or exit the body of the stator 205, and then the conductors 210 may travel in a given direction. As described herein, the slots 220 may include one or more layers 255, and the layer 255 may define or represent the placement of the conductors. For example, the first layer 255 may represent the first position. As another example, the second layer 255 may represent the second position. The first slot 220 may include a first conductor 210 and a second conductor 210. The first conductor 210 may be located in the first layer or the front layer 255, and the second conductor may be located in the second layer or the subsequent layer 255. The first conductor 210 may include one or more portions. For example, the first conductor may include portion 305 and portion 310. Portion 305 may travel in one or more directions outside of the slot 220. For example, portion 305 may travel in direction 320. Portion 310 may travel in one or more directions outside of the slot 220. For example, portion 310 may travel in direction 315. As Figure 3 shown, portion 310 traveling in direction 315 forms a spacing between the conductor 210 in the first layer 255 and the conductor 210 in the second layer 255. The conductors 210 in the second layer may also travel in one or more directions. For example, the conductors in the second layer may travel in direction 320.

[0036] Figure 4 is a perspective view of the conductor 210. The conductor 210 may include or undergo one or more turns. For example, the conductor 210 may have one or more bends or curves. Continuing with this example, the bend or curve may refer to or include a turn. As Figure 4 shown, the conductors 210 may overlap each other. For example, the first conductor 210 may be on top of or at a higher level than the second conductor 210. As another example, the first conductor 210 and the second conductor 210 may be wound or interlocked with each other. Figure 4An example depicting the spacing or gap formed between the previous layer conductor 210 and the subsequent conductor 210 in response to the previous layer conductor 210 having moved in direction 315.

[0037] Figure 5 is a perspective view of the motor 200. The stator 205 may include at least one face 505. For example, the stator 205 may include a first face 505 and a second face 505. The face 505 may refer to or include at least one of a top face, a bottom face, a top side face, or a bottom side face. The conductor 210 may be located outside the face 505. For example, a first portion of the conductor 210 may be located outside the first face 505. As another example, a second portion of the conductor 210 may be located outside the second face 505.

[0038] Figure 6 is a perspective view of the motor 200. Figure 6 Depicts an example of a stator 205 that includes one or more first conductors 210 associated with a first phase and one or more second conductors 210 associated with a second phase. Figure 6 Is shown as including a highlighted portion 605 and a highlighted portion 610. The highlighted portion 605 illustrates an example of a slot 220 that includes a plurality of conductors 210 associated with a first phase. The highlighted portion 605 also illustrates that the first conductor or previous conductor 210 (e.g., the previous layer 255 of the first slot 220) has moved in direction 315 to form a spacing between the first conductor 210 and the subsequent conductor 210. The highlighted portion 610 illustrates an example of the first conductor 210 of the highlighted portion 605 that has been transposed or advanced to the first layer 255 of the second slot 220. The highlighted portion 610 also illustrates that the first conductor 210 is flush or aligned with the subsequent conductor 210.

[0039] As Figure 6 shown, the conductors 210 associated with a first given phase are located in three adjacent slots 220, and the conductors 210 associated with a second given phase are also located in three adjacent slots 220. The slots 220 that include the conductors 210 associated with the first given phase may also be associated with the first given phase. The slots 220 that include the conductors 210 associated with the second given phase may also be associated with the second given phase.

[0040] Figure 6 Depicts an example of slots 220 that are bundled or strapped such that one or more slots 220 associated with a given phase are adjacent to subsequent slots 220 that are also associated with the given phase. As Figure 6 shown, the slots 220 are bundled in groups of three such that a first given slot 220 is disposed between a second given slot 220 and a third given slot 220. The groups of three (e.g., the bundled slots 220) may be associated with a given phase. Figure 6Examples of a first set of bundled slots 220 associated with a first phase and a second set of bundled slots 220 associated with a second phase are depicted. Respective subsets of the bundled slots 220 may be adjacent to each other. For example, the set of bundled slots 220 associated with the first phase may be adjacent to the second set of bundled slots 220 associated with the second phase.

[0041] Figure 7 is a perspective view of the motor 200. Figure 7 Examples of a stator 205 are depicted that includes one or more first conductors 210 associated with a first phase, one or more second conductors 210 associated with a second phase, and one or more third conductors 210 associated with a third phase. The stator 205 may include at least one pattern or arrangement. For example, the stator 205 may include conductors 210 arranged in a staggered pattern. In other words, the positions and / or placement of the conductors 210 may be staggered across the stator 205. The staggered pattern may include the bundled slots described herein. For example, three adjacent slots 220 may each receive a conductor 210 associated with a given phase. Continuing with this example, each of the three adjacent slots 220 may receive an odd number of conductors 210. The odd number of conductors 210 may be or include one or more subsets of conductors. For example, the first slot 220 may receive a first subset of conductors 210 from the second slot 220, and the first slot 220 may receive a second subset of conductors 210 from the third slot 220. This bundled slot design may be repeated or reused for one or more slots 220 associated with each phase.

[0042] The pattern of the conductors 210 may include one or more pre - determined or pre - arranged patterns. For example, the first conductor 210 may have a first portion 405 positioned in a first layer 255 of the first slot 220, and the first conductor 210 may have a second portion 405 positioned in the first layer 255 of the second slot 220. As another example, the second conductor 210 may have a first portion 405 positioned in a second layer 255 of the first slot 220, and the second conductor 210 may have a second portion 405 positioned in a third layer 255 of the second slot 220.

[0043] Figure 8 is a flow chart of a process 800 for manufacturing a stator. The stator may include the stator 205. Manufacturing the stator 205 may include providing the stator 205. For example, the stator 205 may be provided during the assembly of the vehicle 105. The stator 205 may be provided in response to having purchased the stator 205.

[0044] At operation 805, an odd number of conductors may be set. For example, an odd number of conductors 210 may be set. The odd number of conductors 210 may be set within the slot 220. The odd number of conductors 210 may be set within the slot 220 by placing, positioning, locating, or otherwise disposing at least one of an even number of conductors 210 within the slot 220. The slot 220 may be associated with a given phase. For example, the slot 220 may be associated with a first phase. The odd number of conductors 210 may be associated with the first phase. The odd number of conductors 210 may include five conductors.

[0045] At operation 810, a subset of the odd number of conductors may be set. For example, in operation 805, a subset of the odd number of conductors 210 set within the slot 220 may also be set within a second slot 220. As another example, a first portion of the odd number of conductors 210 may be set within the slot 220, and a second portion of a subset of the odd number of conductors 210 may be set within the second slot 220. The subset of the odd number of conductors 210 may be set within the second slot 220 by placing, positioning, locating, or otherwise disposing at least one of a subset of an even number of conductors 210 and a first number of conductors within the slot 220. The subset of the odd number of conductors 210 may include at least one of two conductors or three conductors. The second slot 220 may be associated with the first phase. The second slot 220 may be different from the first slot 220. For example, the first slot 220 and the second slot 220 may be different slots.

Although a computer storage medium is not a propagated signal, a computer storage medium can be the source or destination of computer program instructions encoded in an artificially generated propagated signal. A computer storage medium can also be or be included in one or more separate components or media (e.g., multiple CDs, disks, or other storage devices including cloud storage). The operations described in this specification can be implemented as operations performed by a data processing apparatus on data stored on one or more computer - readable storage devices or received from other sources.

[0050] Terms such as "computing device", "component", or "data processing apparatus" encompass various devices, equipment, and machines for processing data, including, for example, programmable processors, computers, system-on-a-chip, or multiple of the foregoing or a combination of the foregoing. The apparatus may include dedicated logic circuitry, such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). In addition to hardware, the apparatus may also include code that creates an execution environment for the computer programs being discussed, such as code that constitutes processor firmware, protocol stack, database management system, operating system, cross-platform runtime environment, virtual machine, or a combination of one or more of them. The apparatus and the execution environment may implement various different computing model infrastructures, such as web services, distributed computing, and grid computing infrastructures.

[0051] A computer program (also referred to as a program, software, software application, application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program can correspond to a file in a file system. A computer program can be stored in a part of a file that holds other programs or data (e.g., one or more scripts in a markup language document), stored in a single file dedicated to the program being discussed, or stored in multiple cooperating files (e.g., files that store one or more modules, subroutines, or portions of code). A computer program can be deployed to execute on one computer or multiple computers located at one site or distributed across multiple sites and interconnected by a communication network.

[0052] The processes and logical flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logical flows can also be performed by dedicated logic circuitry, and the apparatus can also be implemented as dedicated logic circuitry, such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). Devices suitable for storing computer program instructions and data can include non-volatile memory, media, and memory devices, including, for example, semiconductor memory devices such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks or removable disks; magneto-optical disks; and CD ROM and DVD-ROM disks.

The components of the system can be interconnected by any form or medium of digital data communication (such as a communication network). Examples of communication networks include local area networks (“LANs”) and wide area networks (“WANs”), the Internet (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).

[0054] Although the operations are depicted in the drawings in a particular order, these operations need not be performed in the particular order shown or sequentially, and all of the illustrated operations need not be performed. The actions described herein can be performed in a different order.

[0055] Now that some illustrative specific implementations have been described, it is apparent that the foregoing is illustrative and not restrictive, and has been presented by way of example. Specifically, although many of the examples presented herein involve specific combinations of method actions or system elements, these actions and these elements can be combined in other ways to achieve the same purpose. The actions, elements, and features discussed in connection with one specific implementation are not intended to be excluded from similar roles in other specific implementations.

[0056] The language and terminology used herein are for the purpose of description and should not be regarded as restrictive. The use of “including,” “comprising,” “having,” “containing,” “involving,” “characterized by,” and variations thereof herein is intended to cover the items listed thereafter, their equivalents, and additional items, as well as alternative specific implementations consisting only of the items listed thereafter. In one specific implementation, the systems and methods described herein consist of each combination or all of the elements, actions, or components described.

[0057] Any particular implementation or element or action of the systems and methods referred to herein in the singular can also include a specific implementation that includes a plurality of these elements, and any plural form of any particular implementation or element or action herein can also include a specific implementation that includes only a single element. References in the singular or plural form are not intended to limit the presently disclosed systems or methods, their components, actions, or elements to a single or multiple configurations. References to any action or element based on any information, action, or element can include a specific implementation in which the action or element is at least partially based on any information, action, or element.

[0058] Any specific implementation disclosed herein may be combined with any other specific implementation or embodiment, and references to "specific implementation", "some specific implementations", "one specific implementation", etc. are not necessarily mutually exclusive, but are intended to indicate that the particular features, structures, or characteristics described in connection with the specific implementation may be included in at least one specific implementation or embodiment. Such terms as used herein do not necessarily all refer to the same specific implementation. Any specific implementation may be inclusively or exclusively combined with any other specific implementation in any manner consistent with the aspects and specific implementations disclosed herein.

[0059] References to "or" may be construed as inclusive, such that any term described using "or" may indicate any of the single, more than one, and all of the stated terms. References to at least one of a list of terms may be construed as inclusive OR to indicate any of the single, more than one, and all of the stated terms. For example, a reference to "at least one of 'A' and 'B'" may include only 'A', only 'B', and both 'A' and 'B'. Such references used in conjunction with "comprising" or other open-ended terms may include additional items.

[0060] In the case where a technical feature in the drawings, the detailed description, or any claim is followed by a reference numeral, including the reference numeral is for the purpose of enhancing the understandability of the drawings, the detailed description, and the claims. Accordingly, the presence or absence of a reference numeral has no limiting effect on the scope of any claim element.

[0061] The elements and acts may be modified without materially departing from the teachings and advantages of the subject matter disclosed herein, such as variations in the size, dimensions, structure, shape and proportions, parameter values, mounting arrangements, use of materials, color, orientation of various elements. For example, elements shown as integrally formed may be composed of multiple parts or elements, the positions of the elements may be reversed or otherwise varied, and the nature or number or position of discrete elements may be changed or varied. Other substitutions, modifications, changes, and omissions may also be made in the design, operating conditions, and arrangement of the disclosed elements and operations without departing from the scope of the present disclosure.

[0062] For example, the descriptions of positive and negative electrical characteristics may be reversed. An element described as a negative electrode element may be constructed as a positive electrode element, while an element described as a positive electrode element may be constructed as a negative electrode element. For example, an element described as having a first polarity may have a second polarity, while an element described as having a second polarity may have a first polarity. Further relative parallel, perpendicular, vertical, or other positioning or orientation descriptions include variations within + / - 10% or + / - 10 degrees of a purely vertical, parallel, or perpendicular positioning. Unless otherwise explicitly stated, references to "about," "substantially," or other degree terms include variations of + / - 10% from a given measurement, unit, or range. The elements that are coupled may be electrically coupled, mechanically coupled, or physically coupled to each other directly or through intervening elements. Accordingly, the scope of the systems and methods described herein is indicated by the appended claims rather than the foregoing specification, and variations that fall within the meaning and scope of the equivalents of the claims are included therein.
