[0004] The present disclosure generally relates to magnetic tension components and magnetic force adjustment mechanisms. More particularly, the present disclosure describes magnetic components of a computing device that are held together by magnetic force that can be adjusted by a mechanical force mechanism or an electromagnetic mechanism that changes the force between two magnetic components and thus changes the force required to move the two magnetic components relative to each other or completely separate them. Background Art

[0005] Computing devices include components that are configured to move, such as hinges. The hinges of many laptop computers rely on friction in the hinge to hold the components in place at an angle. For example, a user can manually adjust the angle of a laptop screen relative to its keyboard by manually overcoming the friction force to rotate the screen about the hinge. In addition, magnets can be used to hold two components of a computing device together. For example, a tablet computer can be connected to a keyboard via a magnetic connection. The user must apply enough force to overcome the magnetic force to remove the tablet computer from the keyboard.

[0006] In addition, the computing device includes components such as a latch mechanism for closing components, such as closing a lid to a base. Some laptop computers include a mechanism that keeps the lid and the base in contact when the lid is in a closed position. For example, the lid of a laptop computer may be closed to the base of the laptop computer by means of a "button and hook" arrangement, wherein a hook is arranged in the lid or the base to secure the lid to the laptop computer in a closed position, and wherein a button is arranged in the lid or the base to enable a user to release the hook and open the laptop computer. As another example, some laptop computers may include magnets in the lid, the base, or both, wherein the magnetic force holds the lid closed to the base. The user must apply a force to overcome the magnetic force between the lid and the base to open the laptop computer. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The subject matter disclosed herein relates to techniques for forming a magnetic tension mechanism having an adjustment mechanism to assist in the separation or attachment of magnetic components. Computing devices may employ latches, hooks, and magnets to secure movable components of the computing device, such as a lid of a laptop computer or a keyboard / cover of a tablet computer. For example, a laptop computer may include a magnetic component located in the lid of the laptop computer that is configured to magnetically couple with a magnetic component in the base of the laptop computer. The separation mechanism may alter or reconfigure the magnetic components so that the magnetic components are physically separated from each other. Rather than requiring a user to overcome the magnetic forces associated with the magnetic components in the lid and base to pry the computing components apart (such as prying the lid away from the base), the techniques described herein include introducing a force or component that moves the magnetic components laterally to physically separate the magnets and reduce the magnetic forces applied between the magnetic components.

[0033] The computing device may also employ a friction hinge to allow a rotatable component of the computing device (e.g., a display of a laptop computer) to be held in place. An adjustment mechanism may also be used to adjust the magnetic force between two or more magnetic elements within a movable or rotatable computer component. A mechanical adjustment mechanism may apply a force on a magnetic element of the computing device to facilitate the loosening of a computing device component that can be fastened by a magnetic element. The mechanical adjustment mechanism may apply a rotational force at the magnetic element to reduce the magnetic force or reverse the magnetic force. Additionally, the mechanical adjustment mechanism may apply a force parallel to the magnetic force at the magnetic element to assist in the separation of two magnetic elements. In some aspects, an electromagnetic adjustment mechanism may cause a magnetic field that reduces the force between the two magnetic elements or reverses the force between the two magnetic elements.

[0034] In addition, the introduction of convertible computing devices has introduced a series of mechanical engineering problems regarding optimal attachment and detachment mechanisms and associated forces. Convertible computing devices include more than two pieces that can be connected or separated by a user. There are currently many designs on the market. For example, there are attachments for tablets to keyboards, and tablet cover attachments, which have mechanically fixed designs. The attachment and detachment mechanisms and forces do not change, nor can they be changed. However, research has shown that users have different preferences in terms of adhesion and detachment forces, and the ease of attachment and detachment plays a large role in the user's perception and experience of detachable devices. The embodiments described herein allow users to configure the adhesion and detachment forces in various ways to meet specific user preferences. In some examples, the adjustment mechanism can be automatically controlled by logic within the computing device.

[0035] Additionally, laptop computers, two-in-one detachable laptop computers, and convertible devices typically use hinges that combine friction-based torque to provide users with the ability to adjust and set the angle of a display screen. However, these friction-based hinges have pain points and limitations in terms of increased wear, inefficiency in size, lack of customizability because the torque variability is set and non-adjustable, and not allowing proper contact for wireless technology communications due to radio alignment and lens alignment. Embodiments herein also provide a compact, stable, frictionless hinge that uses magnetic attraction along an axis of rotation to allow rotation and set intervals to adjust the angle of a screen on a device, including but not limited to, a laptop computer, a detachable device, and / or a base, using a compact and stable yet simple solution to achieve screen adjustment.

[0036] Finally, the detachable hinge mechanism requires a protruding feature for firmly attaching the cover and the base, which often affects the industrial design of the product. The use of magnets allows the cover and the base to be connected with less impact on the industrial design. The magnetic component can also help overcome the required connector matching force. However, there are several problems with using magnetic components for detachable devices. One problem is that the force required for the firm connection between the cover and the base makes it difficult for the user to separate the two components. In current magnetic detachable products, separating the components requires two hands and a ripping action. Current magnetic solutions also do not allow 120° screen articulation. In user preference studies, 120° is within the range of user preferences for viewing laptop displays. Moreover, when the force of the magnetic connection that allows the screen to articulate increases, the required magnetic force may be too large for people to overcome and may be unsafe. The embodiments of this article allow variable magnetic states required for functional operation and user safety.

[0037] The "magnetic components" referred to herein may include objects made of ferromagnetic or ferrimagnetic materials. In some embodiments, the magnetic components are magnets, wherein the magnetic components are magnetized and can exert a substantially permanent magnetic field. In other embodiments, one of the magnetic components may be a ferromagnetic component, or a ferrimagnetic component, but not a magnet, such as an unmagnetized steel rod, and the other magnetic component is a magnet configured to attract the ferromagnetic component or the ferrimagnetic component, as discussed in more detail below.

[0038] Figure 1 is a block diagram illustrating magnetic elements of a computing device that are physically separated by means of a shearing motion. The computing device may include a first magnetic element 102 and a second magnetic element 104. Figure 1The invention comprises two component pairs, each having a first magnetic element 102 and a second magnetic element 104. The first pair comprises component 106A and component 108A, and the second pair comprises component 106B and component 108B. The transition between the first pair and the second pair is indicated by arrow 116. Figure 1 As shown, the first magnetic element 102 can be integrated with the first component 106A, 106B of the computing device, and the second magnetic element 104 can be integrated with the second component 108A, 106B of the computing device. In some cases, the first component 106A, 106B can be a lid of a laptop computer, and the second component 108A, 108B can be a base of a laptop computer. In other cases, the first component 106A, 106B can be a tablet computer, and the second component 108A, 108B can be a keyboard, a cover, or a stand.

[0039] When the first computing device component 106A and the second computing device component 108B are in close proximity, a magnetic force may exist between the first magnetic element 102 and the second magnetic element 104, as indicated by arrow 110. One or both of the magnetic elements 102 and 104 may be physically displaced by the displacement indicated by arrows 112 and 114. Figure 1 As shown, the displacements 112, 114 can be caused by a lateral force applied to the first magnetic element 102, the second magnetic element 104, or both the first magnetic element 102 and the second magnetic element 104. The displacements 112, 114 are perpendicular to the magnetic force 110 and can be less than the magnetic force 110. Therefore, the user can overcome the magnetic force without applying a force equal to and opposite to the magnetic force 110.

[0040] As indicated by arrow 116, when first magnetic element 102, second magnetic element 104, or both first magnetic element 102 and second magnetic element 104 move laterally due to displacement (whether 112, 114, or both 112 and 114), magnetic force 110 is reduced or eliminated. Once magnetic force 110 is reduced or eliminated, first component 106B can be moved relative to second component 108B, such as if first component 106B is a cover and second component 108B is a base of a computing device. In some examples, first component 106B can be a component to be separated from base component 108B of a computing device.

[0041] In one embodiment, the shift mechanism can be a slider that manipulates the magnetic element along a defined track. In some embodiments, both magnetic elements are magnets. However, in other embodiments, one magnetic element is a magnet, and the other magnetic element is a ferrimagnetic material or a ferromagnetic material, such as steel, but not a magnet. In yet another embodiment, both magnetic elements 102, 104 are magnets, and one or more of the magnetic elements 102, 104 can include a metal back plate. In some embodiments, relative to other embodiments, the metal back plate can increase the magnetic force between the magnetic components.

[0042] The use of a displacement mechanism can reduce the energy required to separate the two magnetic elements 102, 104. By first using a lateral force action to separate the magnetic elements, rather than using a traction force to directly pull the magnets apart, less force is required to separate the magnetic elements. In addition, because the lateral displacement may only require moving one of the magnetic elements 102, 104 in a vertical motion, it is not necessary to move either magnetic element in a motion parallel to the magnetic force within the component, thereby saving space. In addition, the reconfiguration of the polarity of one or more magnetic elements achieved by electrical or physical manipulation of the mechanism can convert the attractive force into a repulsive force. Such a repulsive force can be generated by the rotation of one of the magnetic elements 102, 104 relative to the other, such as Figure 2 as shown in .

[0043] Figure 2 is a block diagram illustrating the magnetic force between two magnetic elements of a computing device, which is reduced and / or reversed via manipulation of magnetic poles. Figure 2 Three pairs of components are included, the first pair includes component 106C and component 108C, the second pair includes component 106D and component 108D, and the third pair includes component 106E and component 108E. The transition between the first pair and the second pair is represented by arrow 202, and the transition between the second pair and the third pair is represented by arrow 204. Moreover, the computing element can include a first magnetic element 102 integrated with the first component 106C, 106D, 106E, and the second magnetic element 104 can be integrated with the second component 108C, 108D, 108E of the computing device. There can be a magnetic force 110, 206 between the magnetic element 102 and the magnetic element 104.

[0044] like Figure 2 As shown in , one of the integrated magnetic elements 104 can be rotated about a central axis as shown by the dashed line with arrows 208, 210. Figure 2In the example of , the second magnetic element 104 has been rotated 90 degrees around its central axis so that the north pole (indicated by the "+" sign) faces the outside of the illustration in component 108D. By rotating the magnetic element 104 90 degrees, the force between the first magnetic element 102 and the second magnetic element 104 will be reduced or eliminated between components 106D and 108D. Therefore, the user will be able to more easily move the computing device component 106D away from the computing device component 108D. In some examples, the total rotation angle can be adjustable by the user. In some examples, the total rotation angle can be automatically adjusted by an electronic mechanism. For example, the electronic mechanism can be a motor that moves the mechanical component. In some examples, the rod can be connected to the magnetic element so as to be rotated, thereby reducing the magnetic force 110 or reversing the magnetic force 110 by the rotational displacement of the magnetic element 104. In some examples, the rod can be attached to a knob for manual rotation. In some examples, the rod can be attached to a motor. For example, a motor can be used for automatic rotation of the rod.

[0045] The second magnetic element 104 can be rotated another 90 degrees, such as Figure 2 206. As indicated by arrow 210, the second magnetic element 104 is rotated a total of 180 degrees from its original position in 108C, resulting in an orientation of the second magnetic element 104 in 108E. When the second magnetic element 104 is thus rotated a total of 180 degrees from its original position in 108C, the polarity of the second magnetic element 104 is reversed from its orientation in 108C. Therefore, the original attractive force 110 between the magnetic element 102 and the magnetic element 104 is also reversed, and a magnetic repulsive force is caused as indicated by magnetic force 206. Repulsive force 206 can assist a user in separating computing device components 106E and 108E from each other. For example, repulsive force 206 can allow a person to separate component 106E from component 108E using only one hand.

[0046] The use of a rotational force on the magnetic elements 102, 104 may thus result in the generation of a repulsive force 206 to assist a user in separating the computing components 106, 108. However, in some instances, the design may want to minimize magnetic movement, perhaps to provide a stable magnetic field. In this case, Figure 3 The distractive force in the magnet minimizes magnetic motion.

[0047] Figure 3 is a block diagram illustrating a magnetic element of a computing device that is physically pulled to modify the attraction between two magnetic components. Figure 3Two pairs of components are included. The first pair includes component 106F and component 108F, while the second pair includes component 106G and component 108G. Components 108F and 108G include mechanical components 302. In some examples, mechanical components 302 can be shape memory alloy actuators that can generate a force sufficient to pull magnetic element 104 from force 110. In some examples, the mechanical components can include a small motor, a piezoelectric motor, a gear, a lever, or a cam. The transition between the first pair of components and the second pair of components is indicated by arrow 304.

[0048] exist Figure 3 In some examples, mechanical component 302 can be used to pull magnetic element 104 away from the direction of the magnetic force. As indicated by arrow 304, force 110 caused by displaced magnetic element 104 can be reduced. In some examples, magnetic element 104 can be pulled away such a distance that a user can easily pull computing device component 106 away from computing device component 108. In some examples, the displacement distance can be configurable or automatically adjustable.

[0049] One benefit of initially utilizing traction to pull the magnetic elements 102, 104 apart is that there is little or no lateral movement involved in such a design. Figure 1 The parallel force mechanism will not require any lateral movement. However, the parallel force mechanism itself cannot produce Figure 2 Or the repulsive force of Figure 4 below.

[0050] Figure 4A is a block diagram showing magnetic elements of a computing device separated by electromagnetic forces. Figure 4A The specific configuration of electromagnetic attachment in may be generally referred to by the reference numeral 400A. Figure 4AThree pairs of components are included. The first pair includes component 106H and component 108H, the second pair includes components 106I and 108I, and the third pair includes components 106J and 108J. Components 108H, 108I, and 108J each have an electromagnet 402. The transition between the first pair and the second pair is indicated by arrow 404, and the transition between the second pair and the third pair is indicated by arrow 406. The presence and relative amount of current in the electromagnet 402 are indicated by lightning beam 408. In some examples, the electromagnet 402 can be used to temporarily adjust the magnetic force between the computing device components 106I, 106J and the computing device components 108I, 108J. The electromagnet 402 can be made of a magnetic material so that the magnetic element 102 creates a north pole on the side of the electromagnet 402 closest to the south pole of the magnetic element 102. The core of the electromagnet 402 can be made of a magnetic material with high magnetic permeability, such as a ferromagnetic metal such as iron, or a ferrimagnetic compound such as ferrite. Opposite magnetic poles in close proximity generate magnetic attraction 110. In some examples, the electromagnet 402 of component 108H can be an electropermanent magnet, which includes a permanent magnet surrounded by a wire coil. The permanent magnet 402 of 108H can be arranged to have opposite magnetic poles facing the closest magnetic element pole. For example, applying an electric current to the electromagnetic coil can be used to temporarily prohibit the attraction of the permanent magnet by changing its magnetic field. In the case of applying an even larger current, the electromagnetic coil can be used to repel the magnetic element 102 from the electromagnet 402. In some examples, the electromagnet 402 can be an electropermanent magnet capable of switching its magnetic poles. For example, the electropermanent magnet can include an electromagnet and a bimaterial permanent magnet, wherein the magnetic field generated by the electromagnet is used to change the magnetism of the permanent magnet. In this case, the magnetism of the permanent magnet can be switched by the electromagnet 402, and will remain in a new polarity state without the need to continuously supply current.

[0051] exist Figure 4A In the example of FIG. 4 , the electromagnet 402 may initially be in an “off” state without any power or current, as indicated by the lack of any lightning bolts. As indicated by the lightning bolts 408, a small current may be applied to the electromagnet 402 in the component 108I, generating a magnetic field around the electromagnet 402. The current may be applied to the wires to generate a magnetic field that counteracts the effect of the magnetic field generated by the magnetic element 102. The interaction of the two magnetic fields may minimize to no force between the electromagnet 402 and the magnetic element 102. The user may then easily pull the component 106I away from the computing device component 108I.

[0052] As shown by arrow 406, in some examples, a relatively large current can be applied to the electromagnet 402 of component 108J to generate a strong magnetic field and the resulting repulsive force 206. The repulsive force can help the user pull the computing device component 106 away from the computing device component 108. In some examples, the electromagnet can cause the polarity of the bi-material permanent magnet to switch, and the switching of the polarity can also cause the repulsive force 206 at the component 108J. In some examples, the repulsive force 206 can push the components 106J and 108J apart by a distance, allowing the user to easily continue to manually separate the two components 106J and 108J. For example, the magnetic repulsive force of the electromagnet 402 can generate a repulsive force greater than the total magnetic force that holds 106J and 108J together. The user can then manually end the separation of component 106J from component 108J.

[0053] Figure 4B is a block diagram illustrating an example of magnetic elements of a computing device separated by electromagnetic forces. Figure 4B The specific configuration of electromagnetic attachment in FIG. 4 may be generally referred to by reference numeral 400B. Figure 4B As shown, permanent magnet 410 may be oriented horizontally with one pole facing left and the other pole facing right. Electromagnetic element 412 may be formed in a "U" shape and magnetically attached to both ends of the bottom side of permanent magnet 410.

[0054] As in the example magnetic attachment mechanism 400A, the force between the permanent magnet 410 and the electromagnet 412 in the electromagnetic attachment mechanism 400B can be reduced or even reversed, depending on how much current is supplied to the electromagnet 412. By using a "horseshoe" or "U" shaped design, the resulting magnetic force can be directed uniquely at the permanent magnet 410. With this design, electromagnetic interference (EMI) can also be minimized because the magnetic permeability of air is lower than the magnetic permeability of the electromagnetic core.

[0055] One benefit of the electromagnetic mechanisms 400A, 400B is that there is no internal movement required for the magnetic elements 102, 410 or the electromagnets 402, 412, reducing space. However, the adjustment mechanisms of the aforementioned examples may be used alone or in any combination to adjust the magnetic force between one component 106 of the computing device and a second component 108 of the computing device. Although a single mechanism is mentioned in the exemplary embodiments below, one or more of the adjustment mechanisms detailed above may be used as an alternative to or in conjunction with the described mechanisms.

[0056] Figure 5A1 is an example computing device having a tablet computer component 106 and a keyboard component 108, the keyboard component 108 having an attachment surface 502 to which the tablet computer component 106 can be attached or detached. In some examples, the attachment surface 502 can be a docking cradle of the keyboard component 108 of the portable tablet computer 106. In some examples, the keyboard component 108 can be a cover 108 that attaches to the tablet computer 106 via magnetic forces. The attachment surface 502 can include one or more magnetic elements that attach to one or more magnetic elements within the tablet computer 106. In some examples, the tablet computer 106 or the keyboard component 108 can include a gyroscope, accelerometer, or proximity sensor to determine the orientation and acceleration of the computing device and the user's actions.

[0057] Figure 5B 1 is a side cross-sectional view of an example computing device in which the tablet component 106 is magnetically attached to the attachment surface 502 of the keyboard component 108. The tablet component 106 can have an axis 504 about which the magnetic element 102 can rotate freely. In an embodiment, the axis 504 can be connected to an electromechanical actuator (not shown). In some examples, the electromechanical actuator can be a shape memory alloy actuator, a motor, a servo motor, a solenoid, or a piezoelectric motor. The keyboard component 108 can have two rollers 506 on which the ends of the tablet 106 can rotate.

[0058] like Figure 5B As shown, the magnetic element 102 of the tablet 106 can be magnetically attached to the magnetic element 104 of the keyboard 108 at the attachment surface 502. As shown by arrow 508, the magnetic force between the magnetic elements 102, 104 can be reduced by moving the magnetic element 104 away from the magnetic element 102 in a direction parallel to and opposite to the magnetic force. For example, a linear actuator can forcibly separate the magnetic element 104 from the magnetic element 102. By reducing the force between the magnetic element 102 and the magnetic element 104 using a linear actuator, a user can more easily separate the component 106 from the component 108.

[0059] In an embodiment, the magnetically detachable hinge connection can exist in different states, depending on the magnetic load required for a particular state. For example, a first state for tablet attachment may require a strong and secure magnetic force, such as 5 lb-F. A second state, for example, to resist torque from screen adjustment and connectors, may be a high force, such as 25 lb-F. A third state, for example, may be an easily overcome separation force, such as 2 lb-F. Figure 1-4 to achieve different magnetic states. In some examples, the attachment force and separation force can be preset based on the load requirement. For example, the load requirement can be the weight of the attached tablet computer 106.

[0060] In some embodiments, the linear actuator may be controlled via the logic of the computing device. In some examples, the logic may be composed at least in part of hardware logic. For example, the logic for controlling the linear actuator may be integrated into the power management logic of the tablet computer 106. Although a linear actuator is used as an example, any adjustment mechanism, whether electromechanical or electromagnetic, may be used and controlled by the logic of the computing device.

[0061] In some embodiments, the linear actuator can be controlled via a graphical user interface (GUI). For example, a GUI switch can be used to conveniently switch the magnetic force between an adhesion force and a weaker separation force. The GUI switch can send a logic signal to the hinge so that the hinge can exist in a separation force state when the user wants to separate the components. The GUI switch can allow the user to quickly reduce the magnetic force to a separation force and separate the tablet computer 106 from the keyboard base 108 with one hand. Similarly, the GUI switch can allow the user to quickly switch the magnetic force to an adhesion force to reconnect the tablet computer 106 to the keyboard base 108. In some examples, once the user has completely removed the tablet computer 106 from the keyboard base 108, the adhesion force can automatically return to the adhesion state. In some examples, by aligning or misaligning the magnets in the array, the adhesion force can be increased or reduced from a weaker separation force to a weaker separation force, as further discussed in Figure 6.

[0062] Fig. 6A is a front perspective view in cross section of an example magnetic attachment mechanism that uses a mechanical mechanism to manipulate the attractive force of a magnetic element. Fig. 6ATwo pairs of components are included. The first pair includes component 106K, component 108K, linear actuator 602A and attachment surface 502A. Component 106K is magnetically connected to component 108K via magnetic element 104A of attachment surface 502A of component 108K. The second pair includes component 106L, component 108L, linear actuator 602B and attachment surface 502B. Component 106L is connected to component 108L via magnetic element 104A in attachment surface 502B of component 108L. The first pair and the second pair each include magnetic elements 102 and 104A. In some examples, the mechanical mechanism for moving magnetic elements 104A, 104B can be one or more linear actuators 602 or one or more manually adjustable knobs 604. Examples using linear actuators 602A, 602B are generally referred to by reference numeral 600A. Linear actuator 602A, 602B can include a motor and a mechanical component that converts the rotation of the motor into linear motion. For example, the mechanical component can be a screw and nut, a rack and pinion, or a cam. The transition between the first pair of components and the second pair of components in example 600A is represented by arrow 606. In addition, in order to control certain magnetic attraction or repulsion characteristics when separating or attaching computer components, the system is expected to benefit from the embodiment of the symmetric and reverse translation of the magnetic component. For example, a gear transmission or a connecting rod system can replace linear actuator 602A, 602B or be used in combination with linear actuator 602A, 602B to move half of the magnet in one direction and move the rest of the magnetic component in the opposite direction. This structure will balance the attraction of the misaligned magnet to help keep the computer components aligned so that it is easy to attach or separate.

[0063] like Fig. 6A As shown, the attachment surface 502A can include a plurality of magnetic elements 104A that are magnetically coupled to corresponding magnetic elements 102 of the tablet computer 106K. In some examples, the magnetic elements 104A can be fixed to a carriage that can rotate or translate along the attachment surfaces 502A, 502B, 502C in a manner that changes the magnetic field. In some examples, the attachment surfaces 502A, 502B can include a linear actuator 602 that can translate the magnetic elements 104A, 104C laterally. For example, in Fig. 6A , magnetic elements 104A and 104C are translated in the direction of arrow 608. The translation of magnetic element 104A can reduce the magnetic force between magnetic elements 102 and 104A, as described above. Figure 1 As discussed in Fig. 6AAs shown, additional magnetic elements 104C may be included in the hinge to maintain a minimum amount of magnetic force between the tablet computer 106K, 106L and the keyboard 108K, 108L. In some examples, multiple magnetic elements 104A may be individually or collectively modified relative to their neighboring pieces to produce a unique magnetic field profile along the attachment surface of the attachment surface 502B. The reduced magnetic force between the magnetic element 102 and the fewer magnetic elements 104C may allow the user to easily remove the tablet computer from the attachment surface 502B of the computing device component 108L. In some examples, the linear actuator 602B may be controlled based on user input to allow configurable settings. For example, the user may adjust the separation force to make it easier to remove the tablet computer 106 from the attachment surface 502. In some examples, the linear actuator 602B may be controlled using a sensor to increase the attractive force for easy alignment while attaching. For example, a proximity sensor may be used to detect that a user is about to attach the tablet computer 106. The linear actuator 602B can then increase the magnetic force between the magnetic elements 102, 104A to allow the two parts 106K, 108K to be attractively joined together. In some examples, the linear actuator 602A can be controlled by means of the orientation of the tablet computer 106K. For example, a horizontal orientation of the tablet computer 106K can indicate attachment, and the linear actuator will position the magnetic element 104A to create a maximum attractive force between the magnetic elements 102 and 104A. Placing the tablet computer on its edge can indicate separation, and the linear actuator can therefore position the magnetic element 104A to minimize attractive forces or create repulsive forces between the magnetic elements 104A and 102, thereby assisting in separation.

[0064] The use of linear actuators 602A, 602B allows for automatic setting of magnetic forces, which can be customized or pre-configured for various conditions. For example, a relatively high adhesion force and a relatively low separation force can be configured to improve the user experience. However, such a mechanism requires electricity to operate, and some applications may require or prefer to minimize any electricity use. If electricity is conserved, a manually operated mechanical mechanism can be used.

[0065] Figure 6B is a front perspective view in section of an example magnetic attachment mechanism that uses a knob 604 to manipulate the attractive force of a magnetic element. The example using the knob 604 is generally designated by the reference number 600B. Figure 6B A pair of components is included, the pair of components including component 106M, component 108M, and knob 604 and attachment surface 502C. Component 106M is connected to component 108M via magnetic element 104B of attachment surface 502C of component 108M. Component 106M includes magnetic element 102, and component 108M includes magnetic element 104B.

[0066] In the example of 600B, knob 604 can be connected to a rod having an external thread that is connected to an internal thread of a component attached to magnetic element 104B. Knob 604 is a mechanical component that can be manually turned or rotated. For example, a user can manually rotate knob 604 and translate magnetic element 104B to the left or right, depending on the direction of rotation.

[0067] In some embodiments, the user can rotate the knob 604 of the attachment surface 502C to turn the machine screw component that causes the magnetic element 104B to translate. The user can fine-tune the force between the magnetic elements 102, 104B by rotating the knob 604. For example, the user can reduce the magnetic adhesion force by rotating the knob 604 in one direction, and then continue to remove the tablet computer 106M from the attachment surface 502C of the keyboard 108M with minimal force. In some examples, the user can increase the magnetic adhesion force by rotating the knob 604 in another direction. For example, the user may want to manually increase the magnetic force before storing the computing device in a backpack.

[0068] Distributed magnetic elements and the ability to translate and / or rotate the magnetic elements of the attachment mechanism introduce unique attachment and / or separation actions that produce physical properties that benefit from magnetic attraction. In some examples, some users can develop specific combinations of magnetic component translation, traction, and rotation that are compatible with specific force displacement characteristics or preferred attachment or separation actions. For example, a user can separate two magnetic elements with just one hand.

[0069] Fig. 7A 6 is a set of front perspective views of a cross section of an example magnetic attachment mechanism that uses a linear actuator 602 and a chamfered edge mechanism to separate magnetic elements 102 and 104 . Fig. 7A Two pairs of components are included. The first pair includes component 106N and component 108N, while the second pair includes component 106O and component 108O. The hinges 502D, 502E of components 108N, 108O also include a plurality of magnetic elements 104, a linear actuator 602, and a sliding chamfered edge mechanism 704 that are held together in a spring-loaded carriage 702. The chamfered edge mechanism 704 includes two chamfered edges. One chamfered edge is connected to the spring-loaded carriage 702. The other chamfered edge is connected to the linear actuator 602. A specific embodiment using the linear actuator 602, the spring-loaded carriage 702, and the chamfered edge mechanism 704 is generally referred to by the reference numeral 700A.

[0070] In some examples, the linear actuator 602 can slide one chamfered edge over the other chamfered edge by pushing one edge into the other edge, as shown by arrow 706. The interaction of the two edges in the chamfered edge mechanism 704 creates a compressive force on the spring 702, while pulling the magnetic element 104 away from the magnetic element 102, as shown by arrow 708. When the magnetic element 104 is moved away from the magnetic element 102, the linear actuator can thereby reduce the magnetic force between the magnetic elements 102 and 104. By thereby reducing the magnetic force between the magnetic elements 102 and 104, the linear actuator 602 can help the user remove the tablet 106O from the attachment surface 502E. After the tablet is removed, the springs 702 can separate from each other as the linear actuator 702 slides the chamfered edge to return the carriage to its original position.

[0071] In some examples, linear actuator 602 can help prevent tablet computer 106N from being dropped prematurely by moving magnetic elements 102 and 104 closer to each other. In some examples, linear actuator 602 can assist a user in docking tablet computer 106N onto attachment surface 502D. For example, linear actuator 602 can increase the magnetic force between elements 102, 104 as the computing device detects a pre-attachment condition, such as a particular orientation of the device.

[0072] Figure 7B is a set of front perspective views of a cross section of an example magnetic attachment mechanism using a rack and pinion 710 to prevent misalignment. Figure 7B Two pairs of components are included. The first pair includes component 106P and component 108P, while the second pair includes component 106Q and component 108Q. Components 106P, 106Q include magnetic elements 102. Components 108P, 108Q include magnetic components 104, which are coupled to rack 710 and pinion 712. The specific embodiment using rack 710 and pinion 712 is generally referred to by the reference numeral 700B.

[0073] exist Figure 7BIn the example of 700B, the rack 710 and the pinion 712 translate the magnetic elements 104 in the base 108P, 108Q in opposite directions to provide a reaction force to prevent misalignment of the components 106P, 106Q. As the pinion 712 rotates in the direction of arrow 714, the pinion 712 causes their corresponding rack 710 to translate in the direction of arrow 716. In some examples, the magnetic element 104 can be connected to the rack 710 and therefore also translate in the direction of arrow 716. In the example 700B, the overall position of the magnetic element 104 does not translate in either direction. Therefore, the components 106P, 106Q of the example do not require guides (not shown) on the components 108P, 108Q to hold the components 106P, 106Q in place relative to the components 108P, 108Q.

[0074] Figure 7C 71 is a set of side views in cross section of an example magnetic attachment mechanism using a crankshaft 716 to displace a magnetic element. Figure 7C Two pairs of magnetic components 102, 104 are included. The magnetic component 104 is mechanically coupled to the crankshaft 716. Certain embodiments use

[0075] In the example of 700C, as the crankshaft 716 rotates, a piston-like motion is created that displaces the magnet 104 in the base 108R. For example, as the crankshaft 176 rotates in the direction of arrow 718, the magnetic element 104 can be pulled in the direction of arrow 720. In some embodiments, the mechanism can involve using a rotary actuator to rotate a shaft containing a cam that achieves displacement of the magnetic element 104 through the cam radial eccentricity.

[0076] Although Figure 6 and Fig. 7A , Figure 7B and Figure 7C Describes the use Figure 1 Translation 112, 114 and Figure 3 The pulling action in Figure 2 The rotating mechanism of FIG. 4 and the electromagnetic mechanism of FIG. 4 can also be used together with or instead of the mechanical mechanism described above at the attachment surface 502. In addition, Figure 1 Any of the adjustment mechanisms of -4 may also be used in conjunction with the frictionless rotation system described below to magnetically attach the first component 106 to the second component 108 or to separate the first component 106 from the second component 108 or to allow for the adjustment of the first component 106 to the second component 108. Figures 8A-8D Frictionless rotational motion about a series of discrete angles in a

[0077] Fig. 8A 802A is an example barrel hinge 802A at positions of 90, 180 and 205 degrees. Fig. 8ASix views 804A, 806A, 808A, 810A, 812A, 814A are included. View 804A is a schematic diagram of the cylindrical hinge 802A at 90 degrees, with the internal magnetic element 102 visible and a pair of magnetic elements 816A magnetically attached. View 806A is a side stereo close-up view of the cylindrical hinge 802A at 90 degrees, with the internal magnetic element 816A visible. View 808A is a schematic diagram of the cylindrical hinge 802A at 180 degrees, with the attached internal magnetic element 818A visible. View 810A is a side stereo close-up view of the cylindrical hinge 802A at 180 degrees, with the internal magnetic element 818A visible. View 812A is a schematic diagram of the cylindrical hinge 802A at 205 degrees, with the internal magnetic element 820A visible. View 814A is a side perspective close-up view of the cylindrical hinge 802A at 205 degrees, with the internal magnetic element 820A visible. As can be seen in views 816A, 818A, and 820A, the cylindrical hinge 802A includes a plurality of magnetic elements arranged radially around the center point of the hinge 802A.

[0078] Multiple magnetic elements within hinge 802A can keep components of the computing device taut at the location of the magnetic elements of the hinge by means of magnetic force. For example, in views 804A, 806A, two magnetic elements 816A keep hinge 802A at a 90 degree angle. In views 808A, 810A, two magnetic elements 818A keep hinge 802A at 180 degrees. In views 812, 814A, magnetic element 820A keeps hinge 802A at 205 degrees. Each pair of magnetic elements 816A, 818A, 820A is kept taut by means of a corresponding pair of magnetic elements 102 on one side of the hinge. In some examples, magnetic element 102 can be a single ferromagnetic strip. In some examples, the magnetic force between the two magnetic elements can be adjustable. Adjustable magnetic force can allow variable torque to be used to adjust the angle. For example, a user can adjust the torque necessary to adjust the angle according to his or her preferences. The embodiments described herein can therefore be considered to provide frictionless variable torque.

[0079] Figure 8B 802B is an example of a cylindrical hinge for frictionless rotation. The cylindrical hinge 802B includes two parts, and the two parts have a ring 804B that holds a rod (not shown) to hold the hinge 802B together. The inner part of the hinge 802B contains a magnetic element 806B. The outer part of the hinge 802B contains a magnetic element 808B. In some examples, the magnetic element 808B can be a relatively inexpensive steel bar. In some examples, the magnetic element 808B can be a corresponding set of magnets that align with the horizontal arrangement of the magnetic element 806B when they are rotated into the magnetic attachment.

[0080] When a barrel hinge 802B is used, computing technology and components may be built into the rod or barrel of the hinge. For example, wireless technology may be included in the barrel hinge 802B, allowing wireless communication between two components of a computing device connected via the hinge 802B. In some cases, the barrel design may be considered bulky, and a slimmer design may be used.

[0081] Figure 8C is an example magnetic attachment mechanism for frictionless rotation and detachment of tablet computer 106 using spine 802C with magnetic elements 102 . Figure 8C The specific construction of the hinge is generally referred to by the reference numeral 800C.

[0082] Figure 8C Three views 804C, 806C, 808C of an example spine 802C are included. In view 804C, a side perspective view shows that the tablet computer 106 can be removed from the keyboard 108. In view 806C, the spine 802C is shown disconnected from the keyboard 108 below from a top view. In view 808C, a larger close-up view of the spine 802C shows that the spine 802C includes a plurality of magnetic elements 102 positioned radially about a centerline and along the length of the spine 802C.

[0083] exist Figure 8B In the example of , multiple magnetic elements can hold the tablet component 106 of the computing device in tension at the location of the magnetic elements 102 of the hinge by means of magnetic force. For example, the magnetic elements 102 can be positioned on the spine 802C so that the tablet can be positioned and magnetically held at 90, 125, and 180 degrees from the closed position. The closed position is when the tablet is laid flat relative to the keyboard 106. In view 808C, for example, the magnetic elements are arranged at different points along the length of the hinge and at different angles in the radial direction. The magnetic elements 102 can also be fastened to a second set of magnetic elements 104 to attach the hinge to a component of the computing device, as discussed below and Fig.8D For example, the magnets in the second plurality of magnetic elements 102 may each have an opposite polarity relative to the magnetic element 104 of another computing device component. In the example of 800C, the computing device component is a tablet computer 106. In some examples, the keyboard 106 may have rollers (not shown) so that the spine 802C rotates thereon. In some examples, Figure 1 Any of the adjustment mechanisms described in -4 may be used to assist in separating the tablet computer 106 from the keyboard 108 .

[0084] The benefit of using spine 802C is a less bulky design than a barrel hinge, and does not require the use of a removable rod. However, in some cases, a design may be preferred without any magnets facing outward on tablet computer 106. For example, Fig.8D Embodiments having magnetic elements 102 facing inward on tablet computer 106 are included.

[0085] Fig.8D is an example of a hingeless attachment and detachment mechanism for frictionless rotation of a tablet computer with magnetic elements. Fig.8D The specific configuration of the hinge is generally designated by the reference numeral 800D.

[0086] Fig.8D Three views 804D, 806D, 808D of an example hingeless magnetic attachment mechanism are included. In view 804D, a side perspective view shows that the tablet computer 106 can be removed from the keyboard 108 and attached at both ends of the keyboard 108. In view 806D, the tablet computer 106 is shown disconnected from the keyboard 108 below from a top perspective view. In view 808D, a close-up view of the hingeless connection 802D shows that the connection 802D includes a plurality of magnetic elements 102 positioned inside the tablet computer 106. One pair of magnetic elements 102 is horizontally facing another pair of magnetic elements 102 on the other side of the attachment of the tablet computer 106 (not shown), and another pair of magnetic elements 102 is facing downward on the bottom side of the tablet computer 106.

[0087] In the example of 800D, the magnetic element 102 may allow the tablet computer 106 to remain at 90 degrees, 125 degrees, or 180 degrees relative to the closed position. As the user rotates the tablet computer 106 relative to the magnetic attachment axis, the corresponding magnetic element in the keyboard 108 can attach and detach the magnetic element 102. Additional magnetic elements 102 can be positioned along the bottom side of the tablet computer 106. For example, in the hingeless connection 800D, the magnetic element 102 on the bottom side of the tablet computer 106 can allow the tablet computer to remain at a 180 degree angle from the closed position. In some examples, the magnetic force attaching the magnetic element 102 to the corresponding magnetic element in the keyboard 108 can be reduced or eliminated to allow the tablet computer 106 to be detached from the keyboard 108. In some examples, the tablet computer 106 can be detached electronically via an electromagnet. In some examples, the tablet computer 106 can be detached electronically via an electromechanical mechanism.

[0088] Fig. 8E Metal strip 802E is used in an example of a hingeless attachment and detachment mechanism for frictionless rotation of a tablet computer with magnetic elements. Fig. 8EFour views 804E, 806E, 808E, and 810E are included. In view 804E, a front perspective view shows a metal strip embedded in base 108. In view 806E, a side perspective view shows metal strip 802E attached to magnetic element 102. In view 808E, a top perspective view shows computing device component 106 removed from computing device component 108. In view 810E, a close-up view shows magnetic hinge 800C attaching component 106 to component 108 of a computing device using metal strip 802E.

[0089] In the example of 800E, the metal strip 802E can allow the tablet computer 106 to be held at different angles relative to the base 108. For example, the tablet computer 106 can be held at 90 degrees, 125 degrees, or 180 degrees relative to the closed position. The metal strip 802E within the base 108 can attach and detach the magnetic element 102 as the user rotates the tablet computer 106 relative to the magnetic attachment axis. In some examples, the magnetic force attaching the magnetic element 102 to the corresponding magnetic element in the keyboard 108 can be reduced or eliminated to allow the tablet computer 106 to be detached from the keyboard 108. In some examples, the tablet computer 106 can be electronically detached via an electromagnet that counteracts the magnetic force of the magnetic element 102. In some examples, the tablet computer 106 can be electronically detached via an electromechanical mechanism.

[0090] Various advantages can be obtained from the embodiments as described herein. Since the frictionless hinge does not have contact or wear to establish the angle, the hinge does not wear or expire over time. In addition, the angular interval and adjustment remain unchanged. For example, a slight touch will not change the angular interval from 90 degrees to 92 degrees. Another advantage comes from the use of fewer parts to form the hinge, and the corresponding savings in manufacturing time and effort. The efficiency in size provides the advantage of more space that can be used for other purposes. The space can be used to accommodate additional features and components. For example, wireless technology using radio or optical signals can be installed and utilize discrete angles and constant contact points on the hinge ends and align correctly. In some examples, the tablet computer 106 can communicate with the keyboard 108 through such wireless technology. In addition, the frictionless variable torque can be customizable in real time by the user or the original equipment manufacturer (OEM). The ease of detachability is another advantage derived from the customizable magnetic force, which can assist the user to remove or attach the component to the magnetic hinge. In some examples, as discussed below, the customizable magnetic force can be automatically switched between different states by the user with the help of a GUI or via the internal logic of the computing device.

[0091] Moreover, it can be seen that Figure 1-4 to adjust the attachment and separation force of the component 102 and the corresponding component in the keyboard 108, or the attachment and separation of the component 106 and the component 108. For example, the translation of the magnetic element 102 can be used to allow the user to adjust the tablet computer 106 from a discrete angle such as 125 degrees to another angle such as 90 degrees. In addition, Figure 1 -4 magnetic adjustment mechanism can be used to maintain the tablet computer 106 in a closed position relative to the keyboard 108, as described below. Figure 9-11 Discussed in more detail in .

[0092] Fig. 9 900 is a side perspective view of a computing device having an example of a sliding displacement mechanism applied to a magnetic element. The computing device 900 includes a first component, such as a cover 906, and a second component, such as a base 904. The computing device 900 may also include a displacement mechanism, such as a button 906, such as Fig. 9 In an embodiment, computing device 900 includes hinge 908. Hinge 908 may allow lid 902 to rotate relative to base 904. Fig. 9 as well as Fig.10 and Fig.11 A laptop computer having a lid and a base is shown, but the techniques described herein may be implemented in other types of computing devices, and in other types of components of computing devices.

[0093] Fig.10 1002 is a side perspective view of a computing device having an example of a sliding displacement mechanism applied to a magnetic element to open a lid of the computing device. Button 906 may be movable, as indicated by arrow 1002. Button 906 may enable lid 902 to be opened, as indicated by arrow 1002. Fig.10 In an embodiment, computing device 900 may exhibit springback. Springback may be a friction force at hinge 908, where the cover may at least slightly spring open once the button is moved at 1002. In some embodiments, springback may also be a tension force of cover 902, where the cover may at least slightly spring open once the button is moved at 1002. Fig. 9 When closed, the lid may have potential energy due to the flexibility or bendability of the lid 902. In either embodiment, movement of the button 906 as indicated at 1002 enables the lid 902 to be opened relative to the base 904. As described above, movement of the button 906 initiates a sliding motion between the magnetic elements, causing the magnetic force between the magnetic elements of the computing device to be reduced or eliminated.

[0094] In an embodiment, the force required to move the magnetic elements apart is indicated by Equation 1:

[0095] F = μ × P + Spring Equation 1

[0096] In Equation 1, the applied force is represented by "F", where μ is the coefficient of friction to move a magnetic element, "P" is the magnetic force between the magnetic elements, and "Spring" is the force required to return the mechanism to its original position in some implementations after it has been displaced. In some embodiments, the force required to move the magnetic element away may include additional factors, such as magnetic resistance to motion, magnetic forces occurring between the magnetic element and other metal parts of the computing device, etc. In some embodiments, materials may be used to reduce the friction of moving the magnetic element. For example, plastic materials may be used between the magnetic elements to reduce the friction between the magnetic elements.

[0097] Fig.11 1 is a side perspective view of a cross-section of an example slide shift mechanism applied to a magnetic element to open a lid of a computing device. The cross-section 1100 of the computing device shows a first magnetic component and a second magnetic component, such as described above with reference to Figure 1 The first magnetic component 102 and the second magnetic component 104 are discussed. The first magnetic component 102 can be arranged in the cover 902 of the computing device 900, and the second magnetic component 104 can be arranged in the base 904 of the computing device 900. In an embodiment, the computing device may include a shifting mechanism, such as a button 906. As indicated by arrow 1002, when the button 906 moves in the direction of arrow 1002, a shifting force can be introduced between the first magnetic component 102 and the second magnetic component 104. As described above, introducing a shift between the magnetic components 102, 104 can ultimately reduce the magnetic force between the magnetic components 102, 104, and the cover 902 can rebound relative to the base 904. Although Fig.11 The shifting mechanism is shown as a button, other mechanisms are possible. For example, the shifting mechanism can be a rolling mechanism configured to enable a user to move one or more magnetic components 102 , 104 laterally and parallel to the edge of the computing device 900 .

[0098] As previously described, the benefits of the lateral displacement mechanism may relate to saving space in the orthogonal direction and / or introducing a more preferred force displacement characteristic. However, any of the above-described magnetic attachment mechanisms of FIGS. 5-11 may be configured so that the magnetic force can be adapted to the user's preference. In some examples, the user can manually adjust the magnetic force by adjusting the configuration of the mechanism. In some examples, the adjustment mechanism includes an automatic adjustment feature that automatically adjusts the magnetic force between the magnetic elements 102, 104 in response to user usage, such as Fig.13 In these examples, electromechanical or electromagnetic mechanisms may be preferred to allow automation, as discussed in more detail below.

[0099] Fig.121 is a block diagram illustrating a method of forming a displacement mechanism of a computing device. The method 1200 includes: At block 1202, a displacement mechanism of a computing device is formed to apply a force applied between a first magnetic element and a second magnetic element of the computing device. The first magnetic element is held in tension with respect to the second magnetic element by a magnetic force between the first magnetic element and the second magnetic element.

[0100] Method 1200 may include additional embodiments. In some embodiments, method 1200 may include: at box 1204, forming a first magnetic element in a first component of a computing device. For example, the first magnetic element may be formed to be arranged in a cover of a computing device such as a laptop computer. In an embodiment, method 1200 may include: at box 1206, forming a second magnetic element in a second component of the computing device. For example, the second magnetic element may be formed to be arranged in a base of the computing device. In any embodiment, the first magnetic element and the second magnetic element are held in tension by means of magnetic force and can be separated by a force applied to either magnetic element by a shifting mechanism. As described above, in one embodiment, the shifting mechanism may be a button that is slidably engaged to introduce force. In some embodiments, both magnetic elements are magnets.

[0113] Fig.15 1500 is a block diagram illustrating a method for automatically adjusting magnetic forces in a computing device. Method 1500 may include: At block 1502, detecting a user intent with a high probability of separating a first computing device component including a first magnetic element from a second computing device component including a second magnetic element. The first magnetic element is held in tension with respect to the second magnetic element by a magnetic force between the first magnetic element and the second magnetic element. In some examples, the probabilistic separation intent may be sensed by, for example, touching a button on a component. For example, a user may press a button or press and hold a button for a specific amount of time. In some examples, a capacitive surface may trigger a high probability separation intent. For example, a finger touching a capacitive touch screen or a capacitive surface on the back of a tablet device may indicate a high probability separation intent. In some examples, the probability of the separation intent may take into account a specific orientation of the computing device. For example, a gyroscope or accelerometer may detect movement of an orientation that would indicate a high probability separation intent.

[0114] In block 1504, the method may include automatically reducing the magnetic force between the first magnetic element and the second magnetic element of the computing device to a separation force, wherein the first magnetic element is still held in tension with respect to the second magnetic element by the magnetic force between the first magnetic element and the second magnetic element. The separation force may allow a user to easily separate the first computing device component from the second device component. In embodiments, the adhesion force may be changed to the separation force by any of the mechanisms described above. In some examples, the separation force may include the above-described Figure 2 and the repulsive force described in Figure 4. In some examples, logic within the computing device can receive an indication that a user is about to separate the components. The logic will then cause the magnetic force to switch to a separation force upon receiving an indication of a high probability of user separation intent.

[0115] In block 1506, the method may include detecting a high probability that a user is attaching a first computing device component to a second computing device component. For example, a high probability of attachment may be sensed by a motion sensor, a magnetic field sensor, etc. In some examples, the sensor may communicate with logic of the computing system to indicate that the user is about to attach a first component of the computing device to a second component of the computing device. For example, the sensor may communicate with power management logic of the computing device to receive user input and adjust attachment and detachment forces accordingly.

[0116] At box 1508, the method may include automatically increasing the magnetic force between the first magnetic element and the second magnetic element to an adhesion force. In an embodiment, the adhesion force may be achieved by any mechanism described in detail above. In some examples, the adhesion force may be automatically switched to a preset adhesion force by logic within the computing system. In some examples, the preset adhesion force may be user-configurable and / or customizable. For example, the user may adjust the adhesion force by using a GUI running in an operating system of the computing device.

[0117] In block 1510, the method may include detecting a plurality of failed separation attempts. A failed separation attempt may be, for example, an attempt by a user to remove a component, which is measured by a change in a magnetic field or a movement sensor such as an accelerometer. In some examples, a pressure sensor or a capacitive touch sensor may be used to detect a failed separation attempt. For example, a sensor may detect that a user touches a capacitive surface, and this may be combined with a force detected at a magnetic element to be considered a failed separation attempt.

[0118] At box 1512, the method may include automatically reducing the magnetic separation force. In an embodiment, the separation force can be reduced by logic in the computing device in response to a predetermined number of failed separation attempts. In some examples, the lower separation force setting can be stored for future use. For example, the lower separation force can be permanently reduced until premature separation is detected. In some examples, the separation force can be reconfigured by the user via a GUI or other interface. For example, the GUI can present a slider bar to the user to visually adjust or reset the separation force.

[0119] In box 1514, the method may include detecting premature separation. Premature separation is when one computing device component separates from another computing device component without a corresponding detected user action. The user action can be detected by a capacitive touch screen, a proximity sensor, etc. For example, the computing device can be in a moving vehicle or backpack. The computing device can be subject to sudden motion, which causes one computing device component to separate from another computing device component. Separation without any detected user interaction can be considered premature separation. For example, when one computing device component separates from another computing device component without detecting any capacitive touch, it can be considered premature separation. In some examples, an emergency situation may be detected. For example, an emergency situation may exist when an accelerometer of the computing device senses that the computing device is falling.

[0120] At box 1516, the method may include automatically increasing the adhesion. In an embodiment, the adhesion setting may be increased by logic in the computing device in response to a premature separation. In some embodiments, the adhesion may be increased when a premature separation is detected. In some embodiments, the adhesion may be increased after a predetermined number of premature separations. In some embodiments, the adhesion may be temporarily increased. In some examples, an emergency situation may be detected and the logic may temporarily increase the adhesion setting. For example, an emergency situation may exist when an accelerometer of the computing device senses that the computing device is falling. The logic may temporarily increase the adhesion to reduce the risk of damage to the computing device when a drop indication is received from the accelerometer.

[0121] Method 1500 may include other embodiments. As described above, the logic in the device may also allow the computing device to adapt the magnetic force to the user's preference. In some examples, the logic may include the hardware logic of the control regulating mechanism. For example, the method may be implemented by a controller connected to a power management processor. In some embodiments, by storing and analyzing historical information of failed attempts and premature separation and other user behaviors, the computing device may automatically adapt to the default adhesion and separation force, or the maximum or minimum magnetic force used. In some embodiments, the logic controlling the separation force and adhesion force may be user programmable and / or customizable. For example, the user may specify or change the threshold value of failed separation attempts, premature separation or emergency situations. The user may also set or reset the default adhesion or separation force by, for example, a GUI slider bar.
