Title: Universal power cord handling device

Description:
FIELD 
     Disclosed embodiments of the present disclosure relate generally to power cords extending from devices, and in particular to power cord handling devices and methods. 
     BACKGROUND 
     With the proliferation of electronic devices, one aspect of manufacturing and otherwise servicing such devices is handling the power cords that are attached to many of the devices. Such devices may include, for example, set-top boxes, television receivers, gaming consoles, media devices, appliances, computing devices, and a plethora of other types of electrical/electronic devices that have power cords attached thereto and extending therefrom. There are multiple steps in a process of manufacturing or otherwise servicing the devices that involve power cord handling. Oftentimes, handling power cord is conventionally done by hand or otherwise involve inefficient and non-adaptable means. For example, under conventional work practices, wrapping power cords into coils is performed by hand and may involve wrapping up to 1000 or more power cords per person per day. Several issues are presented by conventional practices, including ergonomic issues such as pain in hands due to overuse and other personal injuries, inefficiencies, and costs. The trend is toward shorter work windows, with a desire for more productivity. So, safer, more ergonomic, and more productive solutions are lacking. 
     Thus, there is a need to solve these problems and provide for power cord handling devices and methods. These and other needs are addressed by the present disclosure.

     DETAILED DESCRIPTION 
     The ensuing description provides preferred exemplary embodiment(s) only, and is not intended to limit the scope, applicability, or configuration of the disclosure. Rather, the ensuing description of the preferred exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing a preferred exemplary embodiment of the disclosure. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the disclosure as set forth in the appended claims. 
     Various embodiments according to the present disclosure may provide for universal power cord handling devices and methods that solve problems of conventional power cord handling. Various embodiments may provide for adaptable power cord handling devices and methods that may increase efficiencies, increase safety, and eliminate or mitigate ergonomic issues. 
     Various embodiments will now be discussed in greater detail with reference to the accompanying figures, beginning with  FIG.  1   .  FIG.  1    depicts a perspective view of a universal power cord handling device  100 , in accordance with disclosed embodiments according to the present disclosure. The power cord handling device  100  may be configured to wind a power cord extending from a device. The power cord handling device  100  may include a rigid frame assembly  126 . As depicted, the frame assembly  126  may be an assembly of components. 
     The power cord handling device  100  may include a motor enclosure  102  and a base  104  attached to the motor enclosure  102 . The base  104  may be mounted on the motor enclosure  102 . The base  104  may be attached to the motor enclosure  102  in any suitable manner (e.g., fastened with screws or other fasteners) and may be adapted to support other components of the power cord handling device  100  and to provide a work surface in accordance with embodiments disclosed herein. The frame assembly  126  may include the motor enclosure  102  and the base  104 . Other frame configurations may be included in other embodiments. 
     The power cord handling device  100  may be adapted to form a device receiving area  108 . In various embodiments, the device receiving area  108  may be adapted to receive a device, such as a set-top box such as a television receiver, a console such as a gaming console, a media device, an appliance, a computing device, and/or any other type of electrical/electronic device which has a power cord attached thereto and extending therefrom. In preparatory operations to facilitate power cord handling, a device may be disposed in the device receiving area  108 . The device receiving area  108  may include a support plate  110  adapted to support a device in a predetermined height with respect to the base  104 . In some embodiments, the support plate  110  may be adjustable with a quick adjustment mechanism (e.g., a screw adjustment mechanism with a crank, and/or the like) turn to adjust the height of the support plate  110  with respect to the base  104  and, thereby, adjust the height of a device placed in the receiving area  108 . The device receiving area  108  may be partially bounded by one or more guide members  112 . The guide member  112  may be adapted to provide lateral support, act as a stopper, and/or otherwise guide a device placed in the device receiving area in order to facilitate proper placement of the device in the receiving area and securing of the device during cord handling operations. In some embodiments, the guide member  112  may be fastened to the base  104  in any suitable manner. In some embodiments, the guide member  112  may include an adjustment mechanism to adjust the distance between the guide member  112  and one or more other components of on the base  104  (e.g., the control enclosure  114 ). For example, some embodiments of the guide member  112  may include one or more adjustable components that may be laterally spring-loaded in order to contact device when the device is placed in the receiving area  104  in order to provide lateral support to secure the device in the receiving area  104 , where the lateral support forces are directed toward the control enclosure  104  two secure the device against the control enclosure  114 . Thus, the one or more adjustable components may engage the device when the device is placed in the device receiving area  108  (e.g., by way of pushing the device against the one or more adjustable components), with the one or more spring-loaded adjustable components thereafter maintaining contact with the device by force of the spring force(s) until the device is removed from the device receiving area  108 . Accordingly, the device receiving area  108  may adapt to handle and secure different types of devices with varying dimensions. Once the device is disposed in the device receiving area  108 , the device may be in a ready state for power cord handling operations. 
     The power cord handling device  100  may include a wheel assembly  116 . The wheel assembly  116  may be positioned generally opposite the device receiving area  108  with respect to the base  104  in some embodiments.  FIG.  2 A  depicts a perspective view of the wheel assembly  116 , in accordance with disclosed embodiments according to the present disclosure.  FIG.  2 B  depicts a bottom view of the wheel assembly  116 , in accordance with disclosed embodiments according to the present disclosure. 
     The wheel assembly  116  may be adapted to facilitate coiling of a power cord. The wheel assembly  116  may include a wheel base  118  and a protrusion member  120  that extends from the wheel base  118 . In some embodiments, the wheel base  118  and the protrusion member  120  may be integrally formed as a single piece. In some embodiments, the wheel base  118  and the protrusion member  120  may be separate components where the protrusion member  120  is attached to the wheel base  118  in any suitable manner. For example, as illustrated in the non-limiting embodiment of  FIG.  2 B , the wheel base  118  may include holes  119 - 1 ,  119 - 2  for fasteners of any suitable type (e.g., screws and/or the like) to fasten the protrusion member  120  and one or more angle members  124 , respectively, to the wheel base  118 . 
     The wheel assembly  116  may include a wheel assembly motor  132  adapted to rotate the protrusion member  120 , e.g., by way of the wheel base  118  in some embodiments.  FIG.  4 A  illustrates one non-limiting example of a wheel assembly motor  132 , in accordance with certain embodiments according to the present disclosure. The wheel assembly motor  132  may be axially coupled with the protrusion member  120 . The axle  134  of the wheel assembly motor  132  may extend into aperture  136  of the wheel base  118  and may be fastened thereto in any suitable manner (e.g., fastener, mating/interlocking connection, and/or the like). The wheel assembly motor  132  may mounted under the base  104  and in the motor enclosure  102 .  FIG.  4 B  illustrates one non-limiting example of an exposed motor enclosure  102  with the mounted wheel assembly motor  132 , in accordance with certain embodiments according to the present disclosure. For example, the wheel assembly motor  132  may be attached to the motor enclosure  102  via a bus bar and/or the like. 
     A control unit  136  (also referenced herein as “controller” and/or “control system”) may be configured to control the wheel assembly motor  132  as a function of one or a combination of time, revolutions per second, and/or power cord length. For example, once a winding operation of the wheel assembly motor  132  has been initiated (e.g., via activation of a start switch/button  138 ) the control unit  136  may control the wheel assembly motor  132  to turn the protrusion member  120  for a certain duration that based at least in part on the revolutions per second of the operating setting of the wheel assembly motor  132  and a certain length, and/or until a certain tension threshold is detected. In some embodiments, the control unit  136  may include a timer relay (e.g., a dual-channel rail mounted multifunction timer relay and/or the like) that may be configured as a basis for time-limiting the each winding operation of the wheel assembly motor  132 . For example, the timer relay may be set for a duration that ends before the wheel assembly motor  132  would cause the power cord to be jerked by the wheel assembly  116 . In some embodiments, multiple durations may be used for a single winding operation. For example, the timer relay may be set for an initial duration that the control unit  136  uses to control the wheel assembly motor  132  to turn the wheel assembly  116  at a higher rate of speed and/or torque, and then subsequent duration that the control unit  136  uses to ramp down the wheel assembly motor  132  to turn the wheel assembly  116  at a lower and/or decreasing rate of speed and/or torque in order to avoid jerking the power cord. 
     Additionally or alternatively, the tension of the power cord may be detected during the winding operation. In some embodiments, the control unit  136  may detect the tension on the power cord by way of a load sensor. In some embodiments, a load sensor may be included in or communicatively coupled with the wheel assembly motor  132  and configured to detect an operating load of the wheel assembly motor  132  during winding operations. When a threshold load (e.g., resistance) is detected, the control unit  136  and/or the wheel assembly motor  132  may cause the wheel assembly motor  132  to transition to a different operational setting (e.g., a lower speed and/or torque, or a stop). In some embodiments, an initial threshold load detection may correspond to a transition to a first operational setting transition (e.g., to a lower speed and/or torque), and a subsequent threshold load detection may correspond to a transition to a first operational setting transition (e.g., a stop). 
     Additionally or alternatively, in some embodiments, the wheel assembly motor  132  may be sized to stop under a threshold load condition. For example, the wheel assembly motor  132  may include a lower-power motor (e.g., a quarter of a power rating) that may be stopped under loads that are less than that which would cause jerking of the power cord and/or damage to the power cord and/or device. Accordingly, even if a timer of the control unit  136  has not yet timed out during a winding operation, the wheel assembly motor  132  may safely stop winding while keeping the power cord tight. 
     Referring again more particularly to  FIGS.  2 A and  2 B , the wheel base  118  may have various dimensions and forms in various embodiments. For example, some embodiments may have a wheelbase  118  that has a flange-like form, while other embodiments may have different shapes and forms. Some embodiments of the wheelbase  118  may extend further outward from the central, rotational axis, while other embodiments may have minimal lateral extension or no lateral extension beyond the bottom of the protrusion member  120 . With some embodiments, the bottom of the protrusion member  120  may function at the wheelbase  118 , such that no additional wheelbase  118  is included in the power cord handling device  100 . 
     In some embodiments, the protrusion member  120  may be may have a generally circular and/or cylindrical form as in the illustrated example. In some embodiments, the protrusion member  120  may form a hollow interior cavity is in the illustrated example. However, other embodiments may have other forms. In some embodiments, the protrusion member  120  may be formed as a single piece. For example, some embodiments of the protrusion member  120  may have a different exterior shape, such as a triangular, square, or other polygonal exterior shape instead of the generally circular exterior shape depicted. As another example, some embodiments of the protrusion member  120  may not form a hollow interior cavity, but may instead have a solid or generally solid interior. Still further, some embodiments of the protrusion member  120  may not be formed as a single piece, but may include multiple pieces. With a multi-piece protrusion member  120 , the depicted example of the protrusion member  120  may be formed with true or more pieces abutting together. A multi-piece protrusion member  120  may allow for adjustability of the protrusion member to adapt to different diameters or other distances spanning from one side of the protrusion member to the other. This adaptability to different distances may be further facilitated by the protrusion member  120  pieces being adjustably or otherwise movably attached to the wheel base  118  (e.g., with fastener and slot attachment, login slot attachment, and or the like). The attachments of the protrusion member  120  pieces to the wheel base  118  may be quickly loosened, unlocked, and/or unfastened to allow for the adjustment of the positioning of the protrusion member  120  pieces and then subsequent tightening, locking, and/or fastening of the attachments of the protrusion member  120  pieces to the wheel base  118 . In various embodiments, the protrusion member  120  pieces may be hingedly or pivotably attached to the wheel base  118  to allow for quick adjustment of the taper angle of the exterior surfaces of the protrusion member  120  pieces, where the positioning of the protrusion member  120  pieces may maintained by a threaded coupling (e.g., a bolt and sleeve coupling, turnbuckle coupling, and/or the like) coupling the pieces (e.g., attached near the top of the pieces and spanning the distance between the multiple pieces) and may be adjusted by adjusting the threaded coupling. 
     In some embodiments, the exterior of the protrusion member  120  may be formed to have a slight taper as in the example depicted. For example, the tapered exterior may have a 4° angle as in the illustrated example. However, other embodiments may have different angles on the exterior of the protrusion member  120 . The tapered exterior may facilitate coiling of a power cord about the protrusion member  120  and easy removal of the coiled power cord from the protrusion member  120  after the winding process has been performed such that the coiled power cord may be more easily removed from the protrusion member  120  than if there were no taper. Once the coiled power cord is removed from the protrusion member  120  (and the guide arms  140 ), the coiled power cord may be fastened (e.g., with a wire-tie machine). Further, the tapered exterior may facilitate quasi-concentric coiling of the power cord about the protrusion member  120 . When the protrusion member  120  turns, the power cord may be coiled upwardly, e.g., in a upward spiral that may in some embodiments be of decreasing radial distance from the rotational axis and may in some embodiments be of uniform radial distance from the rotational axis. 
     The protrusion member  120 , whether formed as a single piece or adapted as a multi-piece configuration, may include one or more slots  122 . The depicted example shows two slots  122 . The slots  122  may be formed to extend along a longitudinal axis of the protrusion member  120 . Each slot  122  may be adapted to receive a power cord within the slot  122 . In operation, the power cord may be disposed in the slot such that the plug of the power cord is positioned within the cavity formed by the protrusion member  120 . Thus, even with embodiments where the protrusion member  120  is generally solid, one or more slots  122  may be formed within the protrusion member to receive a power cord and one or more spaces on the interior of the protrusion member  120  may be adapted to receive the head/plug of the power cord. Once the power cord is positioned within a slot  122  (e.g., at the bottom of the slot  122 ) with the plug on the interior of the protrusion member  120 , subsequent lending operations may be performed with the winder assembly  116 . The slots  122  may be formed so that the bottom of the slots  122  facilitate an initial positioning of the end portion of the power cord near the plug of the power cord. The bottom of the slots  122  may be at a predetermined height above the wheel base  118  and with respect to one or more angle members  124  in order to position the end portion of the power cord and other portions of the power cord so that the power cord is disposed on a portion of one or more angle members  124  when the wheel assembly  116  winds the power cord about the protrusion member  120 . The height of the bottom of the slots  122  and the curvatures and/or angles of the angle members  124  may be adapted to guide the power cord so that, when the wheel assembly  116  winds the power cord about the protrusion member  120 , a spacing between the bottom of the coiled cord and the wheel base  118  is created. The space (e.g., about a half inch) may facilitate removal of the coiled power cord by allowing for finger placement under the coiled power cord. Further, height of the bottom of the slots  122  and the curvatures and/or angles of the angle members  124  may be adapted to facilitate upward spiraling coiling of the power cord as the wheel assembly  116  winds the power cord about the protrusion member  120 . 
     The slots  122  may have various shapes in various embodiments. In some embodiments, as in the depicted examples, the slots  122  may have a generally rectangular shape. In some embodiments, the slots  122  may have longitudinal sides that taper such that the tops of the slots  122  (i.e., open ends of the slots  122 ) may form wider gaps than the bottoms of the slots  122 . Accordingly, the slots  122  may flare out in some embodiments. Further, in some embodiments, the slots  122  may have a V shape. Other embodiments are possible, such as the slots  122  being formed to have parabolic shapes. The decreasing gaps from top to bottom of the slots  122  may facilitate greater securement to the power cord when the power cord is disposed within the slots  122  and toward the bottom of the slots  122 . Additionally, the decreasing gaps may further allow for adaptability to varying gauges of power cords to accommodate the differences in sizes that may be utilized with the power cord handling device  100 . 
     The power cord handling device  100 , including the frame assembly  126 , may be fabricated to possess material strength and overall structural strength to generate and accommodate the forces involved with disposing devices in the device receiving area  108 , disposing power cords in the guide arms  140  and wheel assembly  116 , and performing other cord handling operations in accordance with embodiments disclosed herein. The various components of the power cord handling device  100  may be formed of any suitable material. Materials of various components may include alloy steels with any suitable carbon content, a polymer-based material, a plastic material, such as a synthetic or semi-synthetic organic material, a nylon-based material, etc. sufficiently structurally sound to form a rigid or semi-rigid components. 
     The wheel assembly  116  may include one or more angle members  124 .  FIG.  3 A  depicts a side view of an angle member  124 , in accordance with disclosed embodiments according to the present disclosure.  FIG.  3 B  depicts a bottom view of the angle member  124 , in accordance with disclosed embodiments according to the present disclosure. In various embodiments, the one or more angle members  124  may be formed integrally with the protrusion member  120  and/or the wheel base  118 . In other embodiments, the one or more angle members  124  may be separate components that may be attached to the protrusion member  120  and/or the wheel base  118  in any suitable manner. 
     The one or more angle members  124  may function to facilitate positioning of the power cord as the wheel assembly  116  winds the power cord about the protrusion member  120 . For example, as disclosed herein, the angle members  124  and the slots  122  may cooperate to create a spacing between the bottom of the coiled power cord and the wheel base  118  when the wheel assembly  116  winds the power cord to facilitate removal of the coiled power cord. Thus, one function of the angle members  124  may be to stop the coiling power cord at a distance above the wheel base  118 . Additionally or alternatively, the angle members  124  and the slots  122  may cooperate to facilitate upwardly spiraled coiling of the power cord when the wheel assembly  116  winds the power cord. Thus, one function of the angle members  124  may be to guide radial positioning of the coiling power cord at spiraling or otherwise decreasing radial distances from the rotational axis of the wheel assembly  116  as the wheel assembly  116  winds the power cord. Additionally or alternatively, the one or more angle members  124  may function to provide support to the protrusion member  120  in some embodiments. 
     The figures depict one non-limiting example of the angle member  124 . However, other embodiments are possible. Further, the figures indicate non-limiting example measurements (e.g., in inches) of one embodiments, but other embodiments may have other dimensions. The angle member  124  may be formed to have curvature  126  in some embodiments. The curvature  126 , along with other dimensions of the angle member  124 , may facilitate the functions of the angle member  124 . Other embodiments may have a different radius of curvature. Still other embodiments may have a straight ramp instead of the curvature  126 . The angle member  126  may include a curvature  128  adapted to abut a curvature of a portion of the protrusion member  120 . For example, the curvature  128  may be formed to have a radius that matches the radius of an exterior portion of the protrusion member  120 . Similarly, the angle member  126  may include a bevel  130  from top to bottom adapted to abut and match the portion of the protrusion member  120 . For example, the bevel  130  may be formed to have an angle that matches the angle of the corresponding portion of the protrusion member  120 . 
     In various embodiments, the power cord handling device  100  may include one or more guide arms  140 . The one or more guide arms  140  may be adapted to cooperatively guide a power cord during a winding operation. In some embodiments, the one or more guide arms  140  may include a first guide arm  140 - 1  and a second guide arm  140 - 2 . In some embodiments, the first guide arm  140 - 1  may correspond to a primary guide arm, and the second guide arm  140 - 2  may correspond to a secondary guide arm.  FIG.  5 A  depicts a side view of the first guide arm  140 - 1 , in accordance with disclosed embodiments according to the present disclosure.  FIG.  5 B  depicts a bottom view of the secondary guide arm  140 - 2 , in accordance with disclosed embodiments according to the present disclosure. The figures depict non-limiting examples of the guide arms  140 . However, other embodiments are possible. Further, the figures indicate non-limiting example measurements (e.g., in inches) of one embodiments, but other embodiments may have other dimensions. In some embodiments, the primary guide arm  140 - 1  may be larger than the secondary guide arm  140 - 2 . In other embodiments, the guide arms  140  may be the same size. 
     Each guide arm  140  may include a base portion  142  and an overhang portion  144 . The first guide arm  140 - 1  and the second guide arm  140 - 2  may be attached to the base  104  via the base portions  142  of the guide arms  140  in any suitable manner. In some embodiments, the guide arms  140  may be fixedly fastened to the base  104 . In some embodiments, the guide arms  140  may be adjustably attached to the base  104  (e.g., via a spring-loaded pivot hinge and an offset male insert stud/extension, and/or the like) to allow for quick adjustment. For example, the guide arms  140  may be lifted a distance from the base  104  to disengage the offset male insert from the base  104  and rotated about a pivot point 180 degrees and lowered to the base  104  to engage the base  104  with the offset male insert and thereby provide an alternative configuration (e.g., a left-handed configuration). The guide arms  140  may be arranged in a parallel configuration where the guide arms  140  are spaced from one another at any suitable distance (e.g., several inches as illustrated). 
     The overhang portion  144  may define a downward-facing depression  146 . The depression  146  may correspond to a curvature in some embodiments. However, in other embodiments, the depression  146  may have other geometries (e.g., a rectangular slot, a V-shaped slot, and/or the like). The geometry of each overhang portion  144  with respect to the corresponding base portion  142  of a guide arm  140  may create a gap  148  between the overhang portion  144  and the base  104  when the guide arm  140  is mounted on the base  104 . The gap  148  may allow for power cords to be moved via the gap  148  into the area under the depression  146 . Accordingly, the gaps  148  may be sized to be larger than a range of power cord diameters. 
     After a power cord has been disposed under the depressions  146  of the guide arms  140 , the guide arms  140  may prevent, mitigate, or otherwise limit flopping and excessive movement of the power cord when the power cord is undergoing a winding operation. The rounded edges of the guide arms  140  in the shape of the depression  146  may be adapted to allow for some freedom of movement of the power cord during the winding operation while preventing, mitigating, or otherwise limiting flopping excessive movement of the power cord. Further, in some embodiments, the guide arms may be positioned on the base  104  at an angle (e.g., more or less a right angle, or another suitable angle) with respect to the device receiving area  108  and the wheel assembly  116  that may facilitate a measure of tautness/tension on the power cord during the winding operation when the power cord contacts one or both of the depressions  146 . 
     Additionally or alternatively, in some embodiments, the guide arms  140  may be positioned slightly lower than the wheel assembly  116  in order to facilitate the winding operation and the measure of tautness on the power cord during the winding operation. Additionally or alternatively, some embodiments of the guide arms  140  may be arranged in offset manner with respect to one another. For example, not only may the guide arms  140  be arranged in a parallel manner along the horizontal plane, but also guide arms  140  may be offset a different heights with respect to one another. As a further example, the secondary guide arm  140 - 2  may be lower than the primary guide arm  140 - 1  and/or the wheel assembly  116 . This may further facilitate keeping a measure of tension on the power cord during a winding operation in order to prevent lumps or other nonconformities in the coiled power cord. The positioning of the guide arms  140  with respect to one another, the wheel assembly  116 , and the device receiving area  108  may be adapted in order to facilitate an automatic removal of the power cord from the guide arms  140  through the gaps  148  at or near the end of a winding operation when there is a measure of tautness on the power cord. Thus, at the end of a winding operation, the uncoiled portion of the power cord may have slid or otherwise moved out from under the guide arms  140  through the gaps  148  and may be more or less disposed in a straight line from the wheel assembly  116  to the device at the device receiving area  108 . This may further facilitate easy and quick removal of the device and power cord (with the coiled portion of the power cord easily removed from the wheel assembly  116  as disclosed herein) from the power cord handling device  100  (e.g., after the coiled portion of the power cord is tied within automatic tie machine). 
     Various embodiments of the car cord handling device  100  may include one or more sensors (e.g., one or a combination of position sensors, measurement sensors, distance sensors, proximity sensors, cameras for optical recognition, image analysis, metrics, and recognition, motion sensors, light sensors, ambient light photo sensors, photodiode photo sensors, optical detectors, photo detectors, color sensors, and/or the like) in order to facilitate power cord handling operations disclosed herein. One or more of the sensors may be attached to any suitable element of the power cord handling device  100  and disposed to capture data indicative of the positioning and/or other characteristics of aspects of the device and/or power cord. By way of example, one or more sensors (e.g., a proximity sensor and/or the like) may detect when a device is placed in the device receiving area  108 . Likewise, additionally or alternatively, one or more sensors may be coupled to or disposed near one or both of the guide arms  140  in order to detect when a power cord is present under the overhanging portions  144  and/or under the depressions  146 . Additionally or alternatively, one or more sensors may be coupled to or disposed near the protrusion member  120  in order to detect when a power cord has been positioned within the slot  122 . Further, one or more sensors may be positioned and configured to detect positioning and/or nonconformities of the power cord as the power cord is coiled with a winding operation. One or more sensors may be disposed on the base  104  and/or otherwise on the device  100  to have various fields of view to detect various features such as positions, surfaces, edges, contours, relative distances, and/or any other suitable indicia of the power cords handled by the device  100 . Some embodiments may automatically detect a coil impression (e.g., an image of the coiling power cord) with one or more sensors and operate the control unit  136  may match the detected power cord to match the characteristics of the quote power cord to one or more coil patterns (e.g., reference images) and either continue winding operations when the detected characteristics match the pattern or stop winding operations when a nonconformity is detected. Some embodiments of the control unit  136  may learn and infer positions of power cords based at least in part on the detected positions of the power cords, with sensors having sensor sensitivity within a few thousandths of an inch. Additional disclosed embodiments may utilize such position sensors in conjunction with other types of sensors, such as one or a combination of the sensor types above, to learn and detect positions, tensions, and/or other characteristics of power cords, as well as other aspects described further herein. Some embodiments of the control unit  136  may facilitate one or more learning/training modes. Some embodiments may perform image analysis of image data captured with one or more of the sensors to determine one or more image baselines for properly disposed devices and/or power cords and/or properly coiled power cords. Subsequently captured image data may be correlated to reference images using any suitable power cord and/or device traits for correlation. 
     Each of the sensors of various embodiments may be communicatively coupled to a receiver of the control unit  136  via wired or wireless communication channels. The sensors, receiver, and/or control unit  136  may include any suitable sensors, controller(s), processor(s), memory, communication interface(s), and other components to facilitate various embodiments disclosed herein. The sensors, receiver, and/or control unit  136  may include any sensor circuitry necessary to facilitate the various embodiments, including without limitation any one or combination of analog-to-digital converter circuitry, multiplexer circuitry, amplification circuitry, signal conditioning/translation circuitry, and/or the like. The data captured by the one or more sensors may be used by the control unit  136  to detect positioning and facilitate system-directed positioning, winding, and extraction operations of the power cord handling device  100 . 
     Sensors and control units may be coupled and connected in a serial, parallel, star, hierarchical, and/or the like topologies and may communicate to the control unit  136  via one or more serial, bus, or wireless protocols and technologies which may include, for example, WiFi, CAN bus, Bluetooth, I2C bus, ZigBee, Z-Wave and/or the like. For instance, one or more sensors and control units may use a ZigBee® communication protocol while one or more other devices communicate with the receiver using a Z-Wave® communication protocol. Other forms of wireless communication may be used by sensors, control units, and the control unit  136 . For instance, sensors, control units, and the control unit  136  may be configured to communicate using a wireless local area network, which may use a communication protocol such as 802.11. 
     In some embodiments, the control unit  136  may store one or more power cord profiles that may include specifications of winding operation control parameters for one or more sets of power cord characteristics, coil patterns, and processes disclosed herein. The profiles may include categories, such as reference image and characteristic data compiled, utilized, and refined via machine learning to facilitate the recognition, characterization, and categorization of devices and power cords disclosed herein. The profiles may include rules for handling the thresholds, different lengths of power cords, operational modes, exceptions, inconsistencies, nonconformities, errors, and/or the like disclosed herein. 
     Thus, in accordance with various embodiments disclosed herein, a power cord handling method may begin with a device being disposed at the device receiving area  108 . In some embodiments, the device may be disposed on the support plate one 10. The device may be between the guide member  112  and the control enclosure  114  in some embodiments. In some embodiments, one or more quick-adjust components of the guide member  112  may be activated to brace the device in the receiving area  108  and against the enclosure  114  and/or another opposing brace that is disposed opposite the guide member  112  across the receiving area  108 . In some embodiments, the securement of the device may be automatic with one or more actuators (hydraulic, pneumatic, electrical, etc., in various embodiments) configured to actuate the one or more quick-adjust components to make contact with the device and secure the device and the device receiving area  108 . In some embodiments, a sensor (e.g., a weight sensor, a proximity sensor, light sensor, image sensor, and/or the like) may detect when a device is present on the support plate  110  or otherwise in the device receiving area  108 , and may send a signal and/or data corresponding to the detection to the control unit  136 . Accordingly, some embodiments of the control unit  136  may detect when the device is properly disposed in the device receiving area  108 . In some embodiments, the automatic securement features may be actuated in response to the detection of the device. 
     The head of the power cord may be disposed in the cavity of the protrusion member  120 , with the end portion near the head being placed within the slot  122 . In some embodiments, a sensor (e.g., a weight sensor, a proximity sensor, light sensor, image sensor, and/or the like) may detect when the plug of the power cord is present within the cavity of the protrusion member  120  and/or when the end portion is present within the slot  122 , and may send a signal and/or data corresponding to the detection to the control unit  136 . Accordingly, some embodiments of the control unit  136  may detect when an end of a power cord is properly disposed in the protrusion member  120 . 
     Interim portions of the power cord may be disposed under the depressions  146  of the overhang portions  144  of the guide arms  140 . In some embodiments, a sensor (e.g., a weight sensor, a proximity sensor, light sensor, image sensor, and/or the like) may detect when the power cord is present under the depressions  146 , and may send a signal and/or data corresponding to the detection to the control unit  136 . Accordingly, some embodiments of the control unit  136  may detect when the power cord is properly disposed under the depressions  146  of the guide arms  140 . The winding operation may be initiated with activation of the start button  138 . In some embodiments, the winding operation may be device-initiated. For example, the control unit  136  may initiate a winding operation upon detection of the device being properly disposed and secured in the device receiving area  108  and detection of the power cord being properly disposed in the protrusion member  120  and under the guide arms  140 . Upon detection of the device not being properly disposed and secured in the device receiving area  108  and/or detection of the power cord not being properly disposed in the protrusion member  120  and/or under the guide arms  140 , the control unit  136  may prevent initiation of the winding operation and/or cause an alert to be surfaced via a user interface (e.g., a display communicatively coupled with the control unit  136 ). Automatic winding operations may be terminated at any moment upon activation of a stop button  150 . 
     As disclosed herein, the control unit  136  may initiate and control rotation of the wheel assembly motor  132  as a function of one or a combination of time, revolutions per second, and/or power cord length. The control unit  136  may further control rotation of the wheel assembly motor  132  as a function of detection of tension of the power cord during the winding operation. In some embodiments, the control unit may ensure that the power cord is coiled in a uniform manner via comparing captured sensor data of the coiling power cord to reference data (e.g., image detection and recognition by way of comparison to reference images). Upon detection of a nonconformity of the coiling power cord satisfy one or more thresholds (e.g., image correlation/match threshold), the control unit  136  may pause the winding operation and/or cause an alert to be surfaced via a user interface. However, upon detection of completion of a winding operation (e.g., by way of one or combination of time detection, tension detection, image detection, and/or other sensor-based detection), the control unit  136  may terminate the winding operation. With the end of the winding operation, the interim portion of the power cord may be removed automatically as disclosed herein or otherwise from the guide arms  140 . The coiled power cord may be removed from the protrusion member  120  and bound with an automated or semi-automated binding machine. 
     In some embodiments, the control unit  136  may be configured to store recordings in volatile and/or non-volatile memory of one or combination of data regarding instances of winding operations (e.g., logging data for instances, cycles, successful completions, stoppages, alerts, and/or the like), winding control data for instances of winding operations (e.g., timing data, revolutions per second, power cord lengths and/or other characteristics), sensor data for instances of winding operations (e.g., tensions, loads, images, and/or the like), and/or the like. In some embodiments, the control unit  136  may create additional or alternative reporting data based at least in part on one or a combination of such recordings. The additional or alternative reporting data may include summary data, averages, medians, frequencies, and/or the like which may be for certain time periods (e.g., averaged over hours, days, etc.). The may surface the reporting data via a user interface and/or may upload the data via one or more networks to a remote computing device. 
     In some embodiments, the control unit  136  may be implemented as a microcontroller-based system. The non-volatile memory of the control unit  136  may store operating instructions, and/or operating instructions may be programmed in a read-only memory. Implementation of the techniques, blocks, steps and means disclosed herein may be done in various ways. For example, these techniques, blocks, steps and means may be implemented in hardware, software, or a combination thereof. For a hardware implementation, the processing units may be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs) or programmable logic controllers (PLCs), field programmable gate arrays (FPGAs), image processors, controllers, micro-controllers, microprocessors, other electronic units designed to perform the functions described above, and/or a combination thereof. 
     With reference to  FIG.  6   , an embodiment of a special-purpose control system  600  is shown. In some embodiments, the special-purpose control system  600  may implement the control unit  136 . The above methods may be implemented by computer-program products that direct a computer system to perform the actions of the above-described methods and components. In some embodiments, the special-purpose control system  600  may be a computer system. Each such computer-program product may comprise sets of instructions (codes) embodied on a computer-readable medium that directs the processor of a computer system to perform corresponding actions. The instructions may be configured to run in sequential order, or in parallel (such as under different processing threads), or in a combination thereof. Merely by way of example, one or more procedures described with respect to the method(s) discussed herein might be implemented as code and/or instructions executable by a computer (and/or a processor within a computer); in an aspect, then, such code and/or instructions can be used to configure and/or adapt a general purpose computer (or other device) to perform one or more operations in accordance with the described methods, transforming the computer into the special-purpose control system  600 . 
     As discussed further herein, according to a set of embodiments, some or all of the procedures of such methods are performed by the control system  600  in response to processor-execution of one or more sequences of one or more instructions (which might be incorporated into the operating system and/or other code, such as an application program) contained in the working memory. Such instructions may be read into the working memory from another computer-readable medium, such as one or more of the non-transitory storage device(s). Merely by way of example, execution of the sequences of instructions contained in the working memory might cause the processor(s) to perform one or more procedures of the methods described herein. 
     It should be noted that  FIG.  6    is meant only to provide a generalized illustration of various components, any or all of which may be utilized as appropriate.  FIG.  6   , therefore, broadly illustrates how individual system elements may be implemented in a relatively separated or relatively more integrated manner. The control system  600  is shown comprising hardware elements that can be electrically coupled via a bus  605  (or may otherwise be in communication, as appropriate). The hardware elements may include one or more processors  610 , including without limitation one or more general-purpose processors and/or one or more special-purpose processors (such as digital signal processing chips, graphics acceleration processors, video decoders, and/or the like); one or more input devices  615 , which can include without limitation a mouse, a keyboard, remote control, and/or the like; and one or more output devices  620 , which can include without limitation a display device, a printer, and/or the like. 
     The control system  600  may further include (and/or be in communication with) one or more non-transitory storage devices  625 , which can comprise, without limitation, local and/or network accessible storage, and/or can include, without limitation, a disk drive, a drive array, an optical storage device, a solid-state storage device, such as a random access memory (“RAM”), and/or a read-only memory (“ROM”), which can be programmable, flash-updateable and/or the like. Such storage devices may be configured to implement any appropriate data stores, including without limitation, various file systems, database structures, and/or the like. 
     The control system  600  might also include a communications subsystem  630 , which can include without limitation a modem, a network card (wireless or wired), an infrared communication device, a wireless communication device, and/or a chipset (such as a Bluetooth™ device, an 802.11 device, a Wi-Fi device, a WiMAX device, cellular communication device, etc.), and/or the like. The communications subsystem  630  may permit data to be exchanged with a network (such as the network described below, to name one example), other computer systems, and/or any other devices described herein. In many embodiments, the control system  600  will further comprise a working memory  635 , which can include a RAM or ROM device, as described above. 
     The control system  600  also can comprise software elements, shown as being currently located within the working memory  635 , including an operating system  640 , device drivers, executable libraries, and/or other code, such as one or more application programs  645 , which may comprise computer programs provided by various embodiments, and/or may be designed to implement methods, and/or configure systems, provided by other embodiments, as described herein. Merely by way of example, one or more procedures described with respect to the method(s) discussed above might be implemented as code and/or instructions executable by a computer (and/or a processor within a computer); in an aspect, then, such code and/or instructions can be used to configure and/or adapt a general purpose computer (or other device) to perform one or more operations in accordance with the described methods. 
     A set of these instructions and/or code might be stored on a non-transitory computer-readable storage medium, such as the non-transitory storage device(s)  625  described above. In some cases, the storage medium might be incorporated within a computer system, such as control system  600 . In other embodiments, the storage medium might be separate from a computer system (e.g., a removable medium, such as a compact disc), and/or provided in an installation package, such that the storage medium can be used to program, configure, and/or adapt a general purpose computer with the instructions/code stored thereon. These instructions might take the form of executable code, which is executable by the control system  600  and/or might take the form of source and/or installable code, which, upon compilation and/or installation on the control system  600  (e.g., using any of a variety of generally available compilers, installation programs, compression/decompression utilities, etc.), then takes the form of executable code. 
     As mentioned above, in one aspect, some embodiments may employ a computer system (such as the control system  600 ) to perform methods in accordance with various embodiments of the invention. According to a set of embodiments, some or all of the procedures of such methods are performed by the control system  600  in response to processor  610  executing one or more sequences of one or more instructions (which might be incorporated into the operating system  640  and/or other code, such as an application program  645 ) contained in the working memory  635 . Such instructions may be read into the working memory  635  from another computer-readable medium, such as one or more of the non-transitory storage device(s)  625 . Merely by way of example, execution of the sequences of instructions contained in the working memory  635  might cause the processor(s)  610  to perform one or more procedures of the methods described herein. 
     The terms “machine-readable medium,” “computer-readable storage medium,” “computer-readable medium,” and that plural forms thereof as used herein, refer to any medium or media that participate in providing data that causes a machine to operate in a specific fashion. These mediums may be non-transitory. In an embodiment implemented using the control system  600 , various computer-readable media might be involved in providing instructions/code to processor(s)  610  for execution and/or might be used to store and/or carry such instructions/code. In many implementations, a computer-readable medium is a physical and/or tangible storage medium. Such a medium may take the form of a non-volatile media or volatile media. Non-volatile media include, for example, optical and/or magnetic disks, such as the non-transitory storage device(s)  625 . Volatile media include, without limitation, dynamic memory, such as the working memory  635 . 
     Common forms of physical and/or tangible computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, or any other magnetic medium, a CD-ROM, any other optical medium, any other physical medium with patterns of marks, a RAM, a PROM, EPROM, a FLASH-EPROM, any other memory chip or cartridge, or any other medium from which a computer can read instructions and/or code. 
     Various forms of computer-readable media may be involved in carrying one or more sequences of one or more instructions to the processor(s)  610  for execution. Merely by way of example, the instructions may initially be carried on a magnetic disk and/or optical disc of a remote computer. A remote computer might load the instructions into its dynamic memory and send the instructions as signals over a transmission medium to be received and/or executed by the control system  600 . 
     The communications subsystem  630  (and/or components thereof) generally will receive signals, and the bus  605  then might carry the signals (and/or the data, instructions, etc. carried by the signals) to the working memory  635 , from which the processor(s)  610  retrieves and executes the instructions. The instructions received by the working memory  635  may optionally be stored on a non-transitory storage device  625  either before or after execution by the processor(s)  610 . 
     It should further be understood that the components of control system  600  can be distributed across a network. For example, some processing may be performed in one location using a first processor while other processing may be performed by another processor remote from the first processor. Other components of control system  600  may be similarly distributed. As such, control system  600  may be interpreted as a distributed computing system that performs processing in multiple locations. In some instances, control system  600  may be interpreted as a single computing device, such as a distinct laptop, desktop computer, or the like, depending on the context. 
     Specific details are given in the above description to provide a thorough understanding of the embodiments. However, it is understood that the embodiments may be practiced without these specific details. For example, circuits may be shown in block diagrams in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, hydraulic, pneumatic, and/or electric control connections, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments. 
     Furthermore, embodiments may be implemented by hardware, software, scripting languages, firmware, middleware, microcode, hardware description languages, and/or any combination thereof. When implemented in software, firmware, middleware, scripting language, and/or microcode, the program code or code segments to perform the necessary tasks may be stored in a machine readable medium such as a storage medium. A code segment or machine-executable instruction may represent a procedure, a function, a subprogram, a program, a routine, a subroutine, a module, a software package, a script, a class, or any combination of instructions, data structures, and/or program statements. A code segment may be coupled to another code segment or a hardware circuit by passing and/or receiving information, data, arguments, parameters, and/or memory contents. Information, arguments, parameters, data, etc. may be passed, forwarded, or transmitted via any suitable means including memory sharing, message passing, token passing, network transmission, etc. 
     For a firmware and/or software implementation, the methodologies may be implemented with modules (e.g., procedures, functions, and so on) that perform the functions described herein. Any machine-readable medium tangibly embodying instructions may be used in implementing the methodologies described herein. For example, software codes may be stored in a memory. Memory may be implemented within the processor or external to the processor. As used herein the term “memory” refers to any type of long term, short term, volatile, nonvolatile, or other storage medium and is not to be limited to any particular type of memory or number of memories, or type of media upon which memory is stored. 
     Moreover, as disclosed herein, the terms “storage medium,” “storage media,” “computer-readable medium,” “computer-readable media,” “processor-readable medium,” “processor-readable media,” and variations of the term may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other machine readable mediums for storing information. The terms, computer-readable media, processor-readable media, and variations of the term, include, but are not limited to portable or fixed storage devices, optical storage devices, wireless channels and various other mediums capable of storing, containing or carrying instruction(s) and/or data. 
     The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and/or various stages may be added, omitted, and/or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims. 
     Specific details are given in the description to provide a thorough understanding of example configurations (including implementations). However, configurations may be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail in order to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations will provide those skilled in the art with an enabling description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure. 
     While the principles of the disclosure have been described above in connection with specific apparatuses and methods, it is to be clearly understood that this description is made only by way of example and not as limitation on the scope of the disclosure. Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other rules may take precedence over or otherwise modify the application of the invention. Also, a number of steps may be undertaken before, during, or after the above elements are considered. Furthermore, while the figures depicting mechanical parts of the embodiments are drawn to scale, it is to be clearly understood as only by way of example and not as limiting the scope of the disclosure. 
     Also, the terms in the claims have their plain, ordinary meaning unless otherwise explicitly and clearly defined by the patentee. The indefinite articles “a” or “an,” as used in the claims, are defined herein to mean one or more than one of the element that the particular article introduces; and subsequent use of the definite article “the” is not intended to negate that meaning. Furthermore, the use of ordinal number terms, such as “first,” “second,” etc., to clarify different elements in the claims is not intended to impart a particular position in a series, or any other sequential character or order, to the elements to which the ordinal number terms have been applied.
