## Background
TECHNICAL FIELD
Embodiments described herein generally relate to a magnetic attachment mechanism for an electronic device.
BACKGROUND
End users have more electronic device choices than ever before. A number of prominent technological trends are currently afoot (e.g., more computing devices, duel displays, more detachable displays, etc.), and these trends are changing the electronic device landscape. One of the technological trends is an electronic device, such as a convertible or hybrid laptop, that has a convertible and/or detachable display and can essentially function as either a laptop or a tablet computer. To provide a compelling tablet experience, the user mechanically separates the display portion (or lid) from the base portion.

Example Embodiments
The following detailed description sets forth example embodiments of apparatuses, methods, and systems relating to a magnetic attachment mechanism for an electronic device. Features such as structure(s), function(s), and/or characteristic(s), for example, are described with reference to one embodiment as a matter of convenience; various embodiments may be implemented with any suitable one or more of the described features.
For purposes of illustrating certain example features of a magnetic attachment mechanism for an electronic device, the following foundational information may be viewed as a basis from which the present disclosure may be properly explained. One of the current technological trends is an electronic device, such as a convertible or hybrid laptop, that has a convertible and/or detachable display and can essentially function as either a laptop or a tablet computer. To provide a compelling tablet experience, the user mechanically separates the display portion (or lid) from the base portion. However, existing mechanisms for separating the display portion and base portion are themselves a detriment to this experience. Currently existing mechanisms require alignment pins on one or both sides of the mechanical interface and those pins are both unsightly and potentially dangerous as they can catch on and damage items nearby the user such as clothing, etc.
Various embodiments describe attachment mechanisms for an electronic device which reduces or eliminates problems caused by alignment pins by hiding the alignment pins when a display portion and a base portion are separated. In one or more embodiments, one or more alignment pin extension/retraction mechanisms use magnetic attraction to facilitate movement of the alignments pins from a hidden configuration to an extended configuration and/or from an extended configuration to a hidden configuration. In a particular embodiment, the alignment pin extension/retraction mechanism may be configured such that upon separation of the display portion and the base portion, the alignment pins are “pulled into” a chassis or housing of the electronic device. In another particular embodiment, the display portion may include magnets within a chassis thereof, and the alignment pins may be disposed within the base portion. When the display portion and the base portion are together, the magnets of the display portion may attract the alignment pins to assist in alignment and mechanical connection between the display portion and the base portion. However, upon separation, the alignment pins of the base portion into the base chassis or housing via gravity and are thereby ‘hidden’ from impacting the end user. In another particular embodiment, magnets that are weaker than those use in the display portion may be added to base portion which assist in pulling-down the alignment pins post-separation thereby hiding the alignment pins faster and with more certainty than relying solely on gravity.
In particular embodiments, after the two halves are mated, a latch may be used for robust mechanical retention. In various embodiments, the magnets may be physical permanent or semi-permanent magnets. In still other embodiments, permanent or semi-permanent magnets may be replaced and/or enhanced by providing current through magnetic coils to generate a magnetic attraction force to further facilitate movement of the alignment pins during a docking or undocking operation. In still other embodiments, a solenoid can be used to move the alignment pins during docking or undocking. In such embodiments, the magnetizing current can be applied until such time the display portion and base portion of the electronic device are docked and/or undocked.
In one or more embodiments, one or more proximity sensors can be utilized to determine whether to extend/retract the alignment pins by detecting whether the display portion and base portion are within proximity and a control module may control the alignment pin extension/retraction mechanisms to extend the alignment pins based upon the proximity. In particular embodiments, the proximity sensor can be course-grain such as a Near Field Communication (NFC) sensor, or fine-grain sensor such as hall effect sensor. In one or more embodiments, the proximity information received from the proximity sensor and/or feedback from the docked electrical connections can be used to determine the on/off state of the magnetizing current.
In one or more embodiments, a watchdog timer may be used to turn off the magnetizing current to limit power consumption when a given action is not carried through to completion. In particular embodiments, the magnetizing current may have multiple values, to vary the magnetic attraction. For example, more magnetic attraction may be required for extension of the alignment pins versus retraction of the alignment pins. In some embodiments, if a retaining latch is used, the magnets, and the magnetizing forces, can be used to passively retain the display portion and the base portion in place after the latch is released.
In other embodiments, another usage for the magnetizing force may be to supplement the magnets that mate the display portion and the base portion of the detachable electronic device. Similar to the alignment pin magnetizing force, the magnetizing current may have multiple values in order to vary the magnetic attraction. For example, more magnetic attraction may be required for attach of the display portion and base portion versus detach of the display portion because it may require more force to pull the display portion and base portion physically together, while less force may be required to the separate the display portion and the base portion.
In one or more embodiments, device usage context may be used to determine the need for attach/detach events. Context may be indicated by the detection of the occurrence of a particular event by the electronic device such as a physical switch event, a user's touch or touchless gesture, etc. In one or more embodiments, a control module may use the detection of the occurrence of a particular event to activate and/or deactivate the alignment pins movement by the one or more alignment pin extension/retraction mechanisms.

FIG. 2A is a simplified view of an embodiment of a magnetic attachment mechanism 200 for electronic device 10 in accordance with one embodiment. In the embodiment illustrated in FIG. 2A, device housing 12 of electronic device 10 includes first alignment pin receptacle 16a, second alignment pin receptacle 16b, a first magnetic element 202a and a second magnetic element 202b. Each of first magnetic element 202a and second magnetic element 202b are constructed of material having magnetic properties capable of exerting a magnetic force upon a magnetically attractive material. In accordance with various embodiments, first magnetic element 202a and second magnetic element 202b is disposed within or upon a surface of device housing 12. In other embodiments, one or more of first magnetic element 202a and second magnetic element 202b may include an electromagnet. In the particular embodiment illustrated in FIG. 2A, first magnetic element 202a is disposed proximate to first alignment pin receptacle 16a and second magnetic element 202a is disposed proximate to second alignment pin receptacle 16b. In the embodiment illustrate in FIG. 2A, first alignment pin 24a and second alignment pin 24b are constructed at least partially of a magnetically attractive material such as a ferrous material, magnetic material, or any other magnetically attractive material.
During a docking operation, as device housing 12 is moved within proximity of docking base 20, the magnetically attractive force provided by first magnetic element 202a attracts first alignment pin 28a and moves first alignment pin 28a into the extended position to engage with first alignment pin receptacle 16a. Similarly, the magnetically attractive force provided by second magnetic element 202b attracts second alignment pin 28b and moves second alignment pin 28n into the extended position to engage with second alignment pin receptacle 16a. Upon docking, first electrical connector interface 18 is in electrical connection with second electrical connector interface 30.
During an undocking operation, as device housing 12 is separated from docking base 20 the magnetically attractive force provided by first magnetic element 202a to first alignment pin 28a is overcome by the force of gravity acting upon first alignment pin 28a. As a result, first alignment pin 28a is dropped into the retracted position within base housing 22. Similarly, as device housing 12 is separated from docking base 20 the magnetically attractive force provided by second magnetic element 202b to second alignment pin 28b is overcome by the force of gravity acting upon second alignment pin 28n. As a result, second alignment pin 28b is dropped into the retracted position within base housing 22. Upon undocking, first electrical connector interface 18 is disconnected from second electrical connector interface 30.
FIG. 2B is a simplified view of an embodiment of a magnetic attachment mechanism 204 for electronic device 10 in accordance with another embodiment. In the embodiment illustrated in FIG. 2B, device housing 12 of electronic device 10 includes first alignment pin receptacle 16a, second alignment pin receptacle 16b, and first magnetic element 202a and second magnetic element 202b. In accordance with various embodiments, first magnetic element 202a and second magnetic element 202b is disposed within or upon a surface of device housing 12. In the particular embodiment illustrated in FIG. 2B, first magnetic element 202a is disposed proximate to first alignment pin receptacle 16a and second magnetic element 202a is disposed proximate to second alignment pin receptacle 16b. In the embodiment illustrate in FIG. 2B, first alignment pin 24a and second alignment pin 24b are constructed at least partially of a magnetically attractive material such as a ferrous material, magnetic material, or any other magnetically attractive material.
In the embodiment illustrated in FIG. 2B, base housing 22 further includes a third magnetic element 206a and a fourth magnetic element 206b disposed within base housing 22. In the embodiment illustrated in FIG. 2B, third magnetic element 206a is disposed below or proximate to first alignment pin 24a within base housing 22 and fourth magnetic element 206b is disposed below or proximate to second alignment pin 24a within base housing 22. In one or more embodiments, third magnetic element 206a is configured to provide a weaker magnetically attractive force in an opposite direction to the magnetic attractive force provided to first alignment pin 24a by first magnetic element 202a when device housing 12 is docked with base housing 22. Similarly, fourth magnetic element 206b is configured to provide a weaker magnetic attractive force in an opposite direction to the magnetic attractive force provided to second alignment pin 24a by second magnetic element 206b when device housing 12 is docked with base housing 22. Each of third magnetic element 206a and fourth magnetic element 206b are constructed of material having magnetic properties capable of exerting a magnetic force upon a magnetically attractive material. In other embodiments, one or more of third magnetic element 206a and fourth magnetic element 206b may include an electromagnet.
During a docking operation, as device housing 12 is moved within proximity of docking base 20, the magnetically attractive force provided by first magnetic element 202a attracts first alignment pin 28a overcomes the magnetically attractive force provided by third magnetic element 206a and moves first alignment pin 28a into the extended position to engage with first alignment pin receptacle 16a. Similarly, the magnetically attractive force provided by second magnetic element 202b to second alignment pin 28b overcomes the magnetically attractive force provided by fourth magnetic element 206b and moves second alignment pin 28n into the extended position to engage with second alignment pin receptacle 16a. Upon docking, first electrical connector interface 18 is in electrical connection with second electrical connector interface 30.
During an undocking operation, as device housing 12 is separated from docking base 20 the magnetically attractive force provided by first magnetic element 202a to first alignment pin 28a is overcome by the magnetically attractive force from third magnetic element 206a and the force of gravity acting upon first alignment pin 28a. As a result, first alignment pin 28a is pulled into the retracted position within base housing 22. Similarly, as device housing 12 is separated from docking base 20 the magnetically attractive force provided by second magnetic element 202b to second alignment pin 28n is overcome by the magnetically attractive force from fourth magnetic element 206b and the force of gravity acting upon second alignment pin 28b. As a result, second alignment pin 28b is pulled into the retracted position within base housing 22. Upon undocking, first electrical connector interface 18 is disconnected from second electrical connector interface 30.

Base housing 22 further includes a first solenoid 210a coupled to first alignment pin 24a and a second solenoid 210b coupled to second alignment pin 24b. First solenoid 210a and second solenoid 210b are each in communication with a control module 212. Although FIG. 2C is illustrated as using first solenoid 210a and second solenoid 210b, in other embodiments any suitable movable magnetic element may be used. Control module 212 is in further communication with a control input 214. In one or more embodiments, control input 214 is configured to receive an input signal indicative of a current operating context of electronic device 10 and provide the input signal to control module 212. Control module 212 is configured to determine whether first alignment pin 24a and second alignment pin 24b are to be extended or retracted based upon the current operating context. In accordance with one or more embodiments, first solenoid 210a is configured to selectively extend first alignment pin 24a from base housing 22 or retract first alignment pin 24a into base housing 22 in response to receiving a first control signal from control module 212. Similarly, second solenoid 210b is configured to selectively extend second alignment pin 24b from base housing 22 or retract second alignment pin 24b into base housing 22 in response to receiving a second control signal from control module 212.
During a docking operation, control module 212 receives an input signal from control input 214 indicative of the current context representative of an intended use of electronic device 10 in a docked mode of operation. In particular embodiments, the input signal may be indicative of selection of a switch, placement of electronic device 10 upon docking base 20, a touch interaction with display screen 14, a gesture by the user detected by electronic device 10 indicating a desire for the user to operate electronic device 10 in a docked configuration. In response to receiving the input signal, control module 212 sends a control signal to first solenoid 210a and second solenoid 210b to cause first solenoid 210a to extend first alignment pin 24a and second solenoid 210b to extend second alignment pin 24b. Upon extending of first alignment pin 24a and second alignment pin 24b, electronic device 10 may be docked with docking base 20. Upon docking, first electrical connector interface 18 is in electrical connection with second electrical connector interface 30.
During an undocking operation, control module 212 receives an input signal from control input 214 indicative of the current context representative of an intended use of electronic device 10 in an undocked mode of operation. In particular embodiments, the input signal may be indicative of selection of a switch, removal of electronic device 10 from docking base 20, a touch interaction with display screen 14, or a gesture by the user detected by electronic device 10 indicating a desire for the user to operate electronic device 10 in an undocked configuration. In response to receiving the input signal, control module 212 sends a control signal to first solenoid 210a and second solenoid 210b to cause first solenoid 210a to retract first alignment pin 24a and second solenoid 210b to retract second alignment pin 24b within base housing 212. Upon retracting of first alignment pin 24a and second alignment pin 24b, electronic device 10 may be undocked from docking base 20. Upon undocking, first electrical connector interface 18 is disconnected from second electrical connector interface 30.
In one or more embodiments, control module 212 may include a watchdog timer configured to turn off the magnetizing current to first solenoid 210a and second solenoid 210b to limit power consumption when a given action has not been performed within a predetermined time period. In a particular embodiment, if control module 212 receives an input signal from control input 214 indicative of a docking operation, control module 212 may cause first solenoid 210a and second solenoid 210b to extend first alignment pin 24a and second solenoid 210b. However, if control module 212 determines that the docking operation has not been completed within a predetermined time period, control module 212 may turn off current supplied to first solenoid 210a and second solenoid 210b thereby retracting first alignment pin 24a and second alignment pin 24b within base housing 22.
In one or more embodiments, the current supplied to first solenoid 210a and second solenoid 210b may be varied by control module 212 among multiple values in order to vary the force exerted upon first alignment pin 24a and second alignment pin 24b based upon whether the current operation is a docking operation or an undocking operation. For example, more force may be required for extension of first alignment pin 24a and second alignment pin 24b during a docking operation as compared to retraction of first alignment pin 24a and second alignment pin 24b during an undocking operation.
FIG. 2D is a simplified view of an embodiment of a magnetic attachment mechanism 216 for electronic device 10 in accordance with another embodiment. In the embodiment illustrated in FIG. 2D, device housing 12 of electronic device 10 includes first alignment pin receptacle 16a and second alignment pin receptacle 16b. Base housing 22 further includes a first solenoid 210a coupled to first alignment pin 24a and a second solenoid 210b coupled to second alignment pin 24b.

Control module 212 is configured to determine whether first alignment pin 24a and second alignment pin 24b are to be extended based upon the proximity signal received from proximity sensor 218. In accordance with one or more embodiments, first solenoid 210a is configured to selectively extend first alignment pin 24a from base housing 22 or retract first alignment pin 24a into base housing 22 in response to receiving a first control signal from control module 212. Similarly, second solenoid 210b is configured to selectively extend second alignment pin 24b from base housing 22 or retract second alignment pin 24b into base housing 22 in response to receiving a second control signal from control module 212.
During a docking operation, control module 212 receives a proximity signal from proximity sensor 218 indicative of device housing 12 being determined to be within proximity of base housing 22. In response to receiving the proximity signal, control module 212 sends a control signal to first solenoid 210a and second solenoid 210b to cause first solenoid 210a to extend first alignment pin 24a and second solenoid 210b to extend second alignment pin 24b. Upon extending of first alignment pin 24a and second alignment pin 24b, electronic device 10 may be docked with docking base 20.

During an undocking operation, control module 212 receives a proximity input signal from proximity sensor 218 indicative of device housing 12 not being determined to be within proximity of base housing 22. In response to receiving the proximity signal, control module 212 sends a control signal to first solenoid 210a and second solenoid 210b to cause first solenoid 210a to retract first alignment pin 24a and second solenoid 210b to retract second alignment pin 24b within base housing 212. Upon retracting of first alignment pin 24a and second alignment pin 24b, electronic device 10 may be undocked from docking base 20.

In addition, control module 212 may turn off first electromagnet 226a and a second electromagnet 226b to remove the magnetic attractive force with fifth magnetic element 224a and second magnetic element 224b. Upon retracting of first alignment pin 24a and second alignment pin 24b, electronic device 10 may be undocked from docking base 20. Upon undocking, first electrical connector interface 18 is disconnected from second electrical connector interface 30.
Another embodiment of a magnetic attachment mechanism for an electronic device includes one or more alignment pins and an electrical connector that are each retractable in a base portion when the electronic device is being operated in an undocked configuration or extended from the base portion when the electronic device is being operated in an undocked configuration.
Systems that mechanically and electrically “dock” to one another are a growing segment within the PC/tablet market. Existing technologies often use a USB3.0 Type C connector as an electrical standard between the two devices. However, the USB Type C connector presents several challenges due to the plug design necessary to implement the connector in a PC/tablet style device. Many of the connectors on the market today are prone to damage during installation of the tablet to the docking station as well as when the user is transporting the docking station without the tablet attached. The connector is exposed to external forces that make it prone to damage. In addition, consumers tend to react unfavorably to devices having protruding components off of the docking station.
Various embodiments provided herein provide a mechanism that may hide and protect the connector/plug between an electronic device and a docking station. In one or more embodiments, extension/retraction mechanism is configured to retract the plug into the base of the docking station. When the connector/plug is “hidden”, it is protected from damage when the docking station is not in use as well as provide a clean interface with no protruding parts. In particular embodiments one or more magnets are configured to automatically active extension of the connector/plug out of the docking station when the electronic device is moved within a predetermined distance of the docking station. In one or more embodiments, the one or more magnets may also provide enough magnetic attraction to automatically connect the connector/plug to the electronic device.

During a docking procedure, first alignment pin 56a is extended at least partially into first alignment pin receptacle 46a, second alignment pin 56b is extended at least partially into second alignment pin receptacle 46b, and second electrical connector 58 is configured to extend into and electrically couple with first electrical connector 48 to facilitate coupling of electronic device 40 with docking base 52. In one or more embodiments, one or more of first magnetic element 50a and second magnetic element 50b are configured to magnetically attract extension/retraction mechanism 64 to extend first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 when device housing 42 is brought within proximity of base housing 54. In still other embodiments, first magnetic element 50a and second magnetic element 50b may be replaced by any other magnetically attractive material such as steel or another metal.
Extension/retraction mechanism 64 is further configured to retract first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 into base housing 54 when electronic device 40 is separated from docking base 52 during an undocking of electronic device 40 from docking base 52.

FIG. 3C illustrates a simplified close-up view of base housing 54 in which first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are at least partially extended from base housing 54.
In one or more embodiments, electronic device 40 is a tablet device, a notebook computer or laptop computer that is configured to be detachable from a base unit. In still other embodiments, electronic device 40 may be any suitable electronic device having a display such as a mobile device, PhabletTM, a personal digital assistant (PDA), a smartphone, an audio system, a movie player of any type, a computer docking station, etc. In yet another embodiment, most of the electronics (e.g., processor, memory, etc.) for electronic device 40 reside in device housing 42. Display screen 44 can be a liquid crystal display (LCD), organic light-emitting diode (OLED), or some other type of display. Display screen 44 may also be a touchscreen display. In an embodiment, electronic device 40 may contain a camera, a microphone, and speakers. Docking base 52 may include any device which may be desirable to attach and detach from electronic device 40 such as a keyboard, docking station, device stand, battery module, etc.
FIGS. 4A-4B are a simplified view of an embodiment of a extension/retraction mechanism 64 for electronic device 40 in accordance with one embodiment. The extension/retraction mechanism 64 includes a support member 70 within base housing 54. Support member 70 is coupled to base housing 54 at a first end via a first leaf spring 72a and at a second end via a second leaf spring 72b. In one or more embodiments, first leaf spring 72a and second leaf spring 72b are configured to apply force to bias support member 70 in a retracted direction toward the interior of base housing 54. In still other embodiments, first leaf spring 72a and second leaf spring 72b may be replaced with any other suitable biasing mechanism such as one or more coil springs. First alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are coupled to and supported by a top surface of support member 70. Support member 70 is further coupled to base housing 54 via a first linear bearing 74a and a second linear bearing 74b. First linear bearing 74a and second linear bearing 74b are configured to allow support member 70 to slide upward within base housing 54 during extending of first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 during a docking procedure, and allow support member 70 to slide downward within base housing 54 during retraction of first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 during an undocking procedure.
Support member 70 further includes a third magnetic element 76a disposed at the first end and a fourth magnetic element 76b disposed at the second end. Although third magnetic element 76a and fourth magnetic element 76b are illustrated as using permanent or semi-permanent magnets, in other embodiments one or more of third magnetic element 76a and fourth magnetic element 76b may be replaced by an electromagnetic or a solenoid such as previously described herein. An electrical cable 78 is coupled to second electrical connector 58 to provide an electrical connection between second electrical connector 58 and one or more components of docking base 52. Support member 70 may further include a support block 80 disposed below second electrical connector 58 to provide robust support for second electrical connector 58 during docking operations.
FIG. 4A illustrates a simplified view of the extension/retraction mechanism in the retracted position. In the retracted position, first leaf spring 72a and second leaf spring 72b apply sufficient downward force on support member 70 to hold first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 within base housing 54.
FIG. 4B illustrates a simplified view of the extension/retraction mechanism in the extended position. In the extended position, first magnetic element 50a and second magnetic element 50b of device housing 42 (not shown) are brought within proximity of third magnetic element 76a and fourth magnetic element 76b, respectively. First magnetic element 50a and third magnetic element 76a exert an attractive magnetic force therebetween, and second magnetic element 50b and fourth magnetic element 76b exert an attractive magnetic force therebetween. The sum of the magnetic force between first magnetic element 50a and third magnetic element 76a and second magnetic element 50b and fourth magnetic element 76b are of sufficient magnitude to overcome the forces of first leaf spring 72a, second leaf spring 72c, and the insertion force between first electrical connector 48 and second electrical connector 58. As a result, first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are pulled into the extended position so that they are able to couple with first alignment pin receptacle 46a, second alignment pin receptacle 46b, and first electrical connector 48, respectively, of device housing 12. Electronic device 40 may then be operated in the docked mode of operation.
During undocking of device housing 42 from base housing 54, first magnetic element 50a and second magnetic element 50b of device housing 42 are moved away from third magnetic element 76a and fourth magnetic element 76b and the sum of the magnetic force between first magnetic element 50a and third magnetic element 76a and second magnetic element 50b and fourth magnetic element 76b are weakened to an extent such that they are overcome by the forces of first leaf spring 72a and second leaf spring 72c. As a result, first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are pulled into base housing 54.
FIGS. 5A-5C are simplified close-up diagrams of a docking procedure between electronic device 40 and docking base 52. In FIG. 5A, electronic device 40 is shown as detached from docking base 52 and first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are hidden within base housing 54. In FIG. 5B, electronic device 40 is shown as in the process of being docked with docking base 52. As electronic device 40 is brought within proximity of docking base 52, first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are in the process of being pulled into an extended position from base housing 54 by the magnetic attraction between the magnetic elements 50a-50b (not shown) of electronic device 40 and magnetic elements 76a-76b of base housing 54 being sufficient to overcome the force of leaf springs 72a-72b and connector insertion force. In FIG. 5C, electronic device 40 is shown as being docked with docking base 52 in which first alignment pin 56a is docked with first alignment pin receptacle 46a, second alignment pin 56b is docked with second alignment pin receptacle 46b, and second electrical connector 58 is docked with first electrical connector 48. If electronic device 40 is later detached from docking base 42, first alignment pin 56a, second alignment pin 56b, and second electrical connector 58 are retracted into base housing 54.

In another particular embodiment, the first input signal is a user input such as a switch input, a touch input on a display screen, or a gesture indicative of either a docking procedure or an undocking procedure of electronic device 10. In 604, control module 212 determines whether the input signal is indicative of a docking procedure or undocking procedure. In 606, if the input signal is determined to be indicative of a docking procedure, the operations continue to 608. In 608, control module 212 sends a control signal to cause one or more of alignment pins and/or a connector of docking base 20 to be extended from base housing 22 and the operations end. In 608, if the input signal is indicative of an undocking procedure, the operations continue to 610. In 610, control module 212 sends a control signal to cause one or more of alignment pins and/or a connector of docking base 20 to be retracted into base housing 22 and the operations end.
