Description

[Technical Field]

[0001] The present disclosure relates generally to electronic devices, and more particularly to lock and location status detection schemes for electronic devices. [Background technology]

[0002] As technology evolves, electronic devices are being produced using increasingly smaller and thinner designs. Many electronic devices, such as laptops and notebooks, are configured with a lid member that includes a display screen that is rotatably attached to a base member and is rotatable between an open position and a closed position. In some devices, certain components may be embedded in the bezel area around the display screen. As devices are designed to be smaller and thinner, the width of the bezel area may also be reduced, potentially limiting the size and number of computer components that can utilize the bezel space. Therefore, creative solutions are needed to accommodate desired computer components in electronic devices while enabling the trend toward reducing the size of such devices.

[0021] As technology evolves, electronic devices such as laptops and notebooks are becoming thinner and lighter. Designers of laptops and other electronic devices with screens often attempt to reduce the size of the device and / or narrow the bezel area around the screen to maximize the size of the screen. However, certain components are often located within the bezel area, which can limit the use of the bezel area for other components and can hinder narrowing of the bezel area. In particular, one magnet of a magnet pair used to lock the device in a closed position may be located within the bezel area of ​​the lid member, and the magnet (or sensor) of a magnet-sensor pair used to detect the status of the lid member may also be located within the bezel area of ​​the lid member. This disclosure introduces an improved locking and position status detection scheme that addresses these issues by reducing the number of magnets used to lock the device and detect the position status, among other example features and advantages.

[0022] FIG. 1 is a schematic diagram of a laptop computer 100 in an open position illustrating a conventional scheme for locking and position status detection. The laptop computer 100 includes a lid member 110 rotatably connected to a base member 120. The connection between the lid member and the base member allows the members to move relative to one another about or around an axis. The connection may be a hinged connection mechanism. In this locking and position status detection scheme, two separate magnets are included in a bezel region 112 of the lid member 110. A first lid magnet 114 included in the bezel region 112 of the lid member 110 serves to magnetically lock the lid member to the base member 120 because the lid magnet engages a base magnet 124 included in the base member when the lid member is closed, as indicated by arrow 130.

[0023] A second lid magnet 116 included in the bezel region 112 of the lid member 110 is used to trigger a Hall sensor 126 included in the base member 120 to detect whether the device is in the open or closed position. As indicated by arrow 140, the second lid magnet 116 and the Hall sensor 126 are positioned within their respective members of the laptop computer such that the magnet and sensor are aligned when the laptop computer is in the closed position.

[0024] 2A is a side view of the base member 120 of the laptop computer 100 in the open position. A base magnet 124 and a Hall sensor 126 are included in the base member. The Hall sensor detects a magnetic field that extends perpendicularly to the top surface of the Hall sensor. To prevent false closed status detection, the Hall sensor 126 and the base magnet 124 are ensured to be sufficiently spaced apart from one another within the base member 120 so that the magnetic field generated by the base magnet is not detected by the sensor.

[0025] 2B is a side view of the lid member 110 and base member 120 of the laptop computer 100 when the laptop computer is in the closed position. When the laptop computer is in the closed position, the first lid magnet 114 and base magnet 124 engage to magnetically lock the lid member and base member relative to one another. Thus, the laptop computer remains in the closed position until an appropriate amount of force is applied to separate the magnets and rotate the lid member and / or base member relative to one another.

[0026] 2B, when the laptop computer is in the closed position, the Hall sensor 126 may detect the magnetic field of the second lid magnet 116 and send a status signal (e.g., by generating an output voltage) to the laptop computer's processor to indicate the closed position. When the lid member is open, the Hall sensor no longer detects the magnetic field and stops sending the status signal (e.g., by no longer generating an output voltage). The absence of a status signal from the Hall sensor may indicate that the laptop computer's lid member is in the open position. The processor may use the status signal from the Hall sensor 126 to determine whether to put the laptop computer to sleep.

[0027] Conventional approaches, such as those shown in FIGS. 1 and 2A and 2B, require separate magnets for locking and position status detection of the laptop computer. These magnets within the bezel area must be spaced apart to maintain a sufficient distance between them to avoid magnetic field interference. Similarly, the base magnet and corresponding sensor must be spaced apart to maintain a sufficient distance between them to avoid magnetic field interference and false triggering by the sensor. Furthermore, the bezel area of ​​the lid member must be sized to accommodate the two magnets and the required spacing between them to perform both the locking and position status detection functions. These constraints may limit the ability to reduce the size of the device and / or optimize the design of the bezel area. Furthermore, such constraints may result in system design complexity and increased system costs. Furthermore, other mechanisms used to automatically lock the base and lid members, such as hinge automatic locking mechanisms, have proven ineffective at providing adequate locking.

[0028] These problems (and additional problems) can be solved by an improved locking and position status detection scheme as disclosed herein. The improved locking and position status detection scheme provides a novel approach to magnet and sensor placement and orientation such that a single magnet on one member of an electronic device, in conjunction with a sensor and magnet on another member of the electronic device, is sufficient to activate the locking and position status detection of the electronic device. In embodiments of the improved locking and position status detection scheme, the characteristics of these sensors can be used to determine the placement and orientation of magnets used to lock (magnetically) opposing members of the electronic device and to detect the position status of the electronic device (e.g., whether one member is in an open or closed position relative to the other member). In one example, Hall sensors can be used because they can detect magnetic fields that extend perpendicular to the top layer of the sensor package. Hall sensors cannot detect magnetic fields that extend parallel to the package top layer. This principle can be used to determine the proper placement and orientation of magnets and sensors so that a single magnet on one member can be used to lock an electronic device and trigger a sensor in conjunction with a sensor and magnet on another member.

[0029] In a particular example (such as that shown in FIG. 3 ), a first magnet is used on the lid member of a laptop computer, a second magnet is used on the base member of the laptop computer, and the sensor is positioned adjacent to and above the second magnet in the base member such that the sensor is positioned between the first magnet in the lid member and the second magnet in the base member when the laptop computer is in the closed position. For example, when the laptop computer is in the closed position, the sensor can be sandwiched between the first magnet and the second magnet. The laptop computer is in the closed position when the lid member and / or the base member are aligned by rotatably adjusting the lid member and / or the base member so that their opposing surfaces are adjacent to and substantially parallel to each other. When the electronic device is in the closed position, the first magnet is selected to generate a magnetic field with magnetic flux lines perpendicular to the magnetic field detection region (e.g., the top surface) of the sensor. The second magnet is selected to generate a magnetic field with magnetic flux lines parallel to the magnetic field detection region of the sensor. During the "open lid mode," the sensor communicates to the processor that the lid member is open (e.g., by not sending any signal) because the sensor is not triggered by the parallel (e.g., horizontal) magnetic field from the base magnet. During the "closed lid mode," the lid magnet approaches the sensor, and the sensor detects the perpendicular magnetic field from the lid magnet. Thus, the sensor communicates to the processor that the lid member is closed (e.g., by sending a signal to the processor). Also, the opposing poles of the lid magnet and base magnet are magnetically attracted as they move closer together and engage, providing a locking mechanism for magnetically holding (or locking) the lid member and base member adjacent to one another and substantially parallel. Furthermore, it will be apparent that the broad concept of a single magnet located on one member of an electronic device with a sensor and a second magnet located on the other member of the electronic device can be used in countless different electronic devices having two members that move relative to one another and for which locking mode and position status detection are desired.

[0030] The improved locking and position status detection scheme shown and described herein can provide many advantages. For example, in an electronic device such as a laptop, the improved status detection scheme can be implemented in a reduced-volume bezel area on the laptop's lid. The bezel area of ​​laptops and other electronic devices with screens is typically densely populated with other features, such as cameras, vision companion chips, microphones, and various radio frequency (RF) antennas (e.g., LTE, AUX, Main, etc.). The improved locking and position status detection scheme can be implemented using a single magnet in one component (e.g., in the bezel area in some designs), allowing for more flexible placement of the remaining magnets because the improved scheme does not require maintaining a distance between the sensor and the magnet. Furthermore, using a single magnet in one component to both lock the device and trigger the position status sensor can reduce the complexity of the system design and may also reduce the cost of implementing the locking and position status detection functions.

[0031] Referring to FIG. 3, FIG. 3 is a schematic diagram of an exemplary laptop computer 300 in an open position illustrating an improved locking and position status detection scheme according to at least one embodiment. The laptop computer 300 includes a lid member 310 rotatably connected to a base member 320. The connection between the lid member and the base member allows them to move relative to one another about or around a fixed axis. This axis may be defined by connection points 305 in the form of hinges that rotatably connect the lid member and the base member at opposite ends of the lid member and the base member. A display screen 318 may be included in the lid member 310 and may be visible through an inner surface 311 of the lid member. A bezel region 312 may be defined between an edge of the display screen 318 and the perimeter of the lid member 310. The bezel region may partially or completely surround the display screen 318. In one example, inner surface 311 may be a glass cover, a tempered glass cover, or any other suitable material through which the display can be viewed and which may optionally be used to implement touchscreen functionality. Inner surface 311 may be a single surface that extends across the bezel area and the display screen. Alternatively, inner surface 311 may include a combination of two or more separate surfaces. For example, the bezel area may have one bottom surface of any suitable material, and the display screen may have a separate bottom surface of any suitable material.

[0032] In one example, a keyboard 328 may be provided within the base member 320 and integrated with the top surface 321 of the base member. Similarly, a touchpad 323 may be provided within the base member 320 and integrated with the top surface 321 of the base member.

[0033] In this improved locking and position status detection scheme, a single lid magnet 314 is included in the bezel region 312 of the lid member 310. The lid magnet 314 engages with a base magnet 324 included in the base member 320 to magnetically lock the lid member 310 to the base member 320 in the closed position. In one example, the lid member and base member can be locked in the closed position as a result of magnetic attraction between the lid magnet 314 and the base magnet 324. The lid member 310 and base member 320 can be magnetically held together such that the inner surface 311 of the lid member 310 is adjacent to and substantially parallel to the top surface 321 of the base member 320.

[0034] As indicated by arrow 330, sensor 326 may be included in base member 320 and may be positioned on at least a portion of base magnet 324 such that sensor 326 is positioned between lid magnet 314 and at least a portion of base magnet 324 when the laptop computer is in the closed position. Thus, when the laptop computer is in the closed position, the single lid magnet 314 is sufficiently close to base magnet 324 and sensor 326 to be attracted to and engage base magnet 324 and to allow sensor 326 to detect the magnetic field of the single lid magnet 314.

[0035] The single lid magnet 314 included in the bezel region 312 of the lid member 310 may be embedded in, attached to, or otherwise fixed to, on, or within the lid member 310. Similarly, the sensor 326 and / or base magnet 324 included in the base member 320 may be embedded in, attached to, or otherwise fixed to, on, or within the base member 320.

[0036] 4A is a schematic side view of the base member 320 of the laptop computer 300 in the open position. A base magnet 324 and a sensor 326 are included in the base member, with the sensor 326 disposed on at least a portion of the base magnet. In the open position, the lid member 310 is not parallel (or substantially parallel) to the base member 320. Thus, in the open position, the lid magnet 314 is not aligned with the sensor 326. In at least one embodiment, the sensor 326 can be configured to detect a magnetic field having flux lines perpendicular to the sensor's detection mechanism. In one example, the sensor 326 can be a Hall sensor. However, any other sensor or switch that detects a magnetic field and generates an output signal in response to detection (or lack of detection) can be used.

[0037] In embodiments, sensor 326 may be configured with top layer 327 as a detection mechanism for detecting a magnetic field extending perpendicularly to the top layer. Sensor 326 may be oriented such that top layer 327 is at least substantially parallel to top surface 321 of base member 320, and thus substantially parallel to inner surface 311 of lid member 310, when base member 320 and lid member 310 are in the closed position. The configuration and orientation of base magnet 324 may be selected to generate a magnetic field having magnetic flux lines 325 that are generally parallel to, but not perpendicular to, the sensor's detection mechanism (e.g., top layer 327). Thus, base magnet 324 may be oriented to prevent the magnetic field from being detected by sensor 326.

[0038] In one example, the base magnet 324 may be configured with a north (N) and south (S) pole and oriented to generate a magnetic field with magnetic flux lines 325 generally parallel to the upper layer 327 (and top surface 321) of the sensor 326 of the base member 320. The base magnet 324 may, for example, be an axially magnetized bar magnet oriented longitudinally within the base member 320 to generate a magnetic field with magnetic flux lines 325 generally parallel to the upper layer 327 of the sensor 326. Thus, the sensor 326 will not be triggered by the magnetic field of the base magnet 324, even if the sensor is positioned on top of the base magnet. Furthermore, the base magnet 324 may be positioned such that its north (N) end is adjacent to but below the sensor 326. This allows a single lid magnet (e.g., 314) with its south pole end facing the base member 320 to act as a trigger for the sensor 326 and magnetically engage the base magnet 324.

[0039] FIG. 4B is a schematic side view of the lid member 310 and base member 320 of the laptop computer 300 when the laptop computer is in the closed position. In the closed position, the inner surface 311 of the lid member 310 faces the top surface 321 of the base member 320 and is at least substantially parallel to and adjacent to the top surface of the base member. In at least one embodiment, the inner surface of the lid member may be separated from the top surface of the base member by a small gap. In other embodiments, the inner surface of the lid member may abut the top surface of the base member. In this example, the lid magnet 314 includes a north pole (N) and a south pole (S) and is positioned such that the south pole (S) is aligned with and faces the sensor 326 when the laptop computer is in the closed position. The lid magnet 314 is further constructed and arranged to generate a magnetic field having magnetic flux lines 315 perpendicular to the inner surface 311 of the lid member 310. Thus, when the laptop computer is in the closed position, the magnetic field extends perpendicular to the top layer 327 of the sensor 326. Also, when the laptop computer is in the closed position, the lid magnet 314, a portion (e.g., the north pole) of the base magnet 324, and the sensor 326 can be aligned so that the sensor is positioned between the lid magnet and that portion of the base magnet.

[0040] 4B, when the laptop computer is in the closed position, the south pole (S) of the lid magnet 314 and the north pole (N) of the base magnet 324 engage at 329 to magnetically hold the lid and base members together such that the inner surface 311 of the lid member 310 is at least substantially parallel to and adjacent to the top surface 321 of the base member 320. Thus, the lid and base members may remain in the closed position until an appropriate amount of force is applied to separate the magnets by rotationally moving the lid and / or base members away from each other about the fixed axis of connection point 305.

[0041] Further, when the laptop computer is in the closed position, as shown in FIG. 4B , the sensor 326 detects the magnetic field of the lid magnet 314. The sensor may provide a position status signal to a processor of the laptop computer 300 to indicate that the laptop computer is in the closed position. If the lid member is rotated away from the base member (or vice versa), the sensor 326 no longer detects the magnetic field, indicating that the laptop computer is in the open position. In at least one embodiment, the sensor 326 may stop sending the position status signal to the processor as an indication that the laptop computer is in the open position. In some cases, the processor may use the position status signal from the sensor 326 (and / or without the status signal) to determine whether to put the laptop computer to sleep or to wake.

[0042] 5A and 5B are block diagrams illustrating the magnetic field detection mechanism within a Hall sensor 510. As shown in FIG. 5B, the Hall sensor's integrated circuit cannot detect magnetic fields that extend parallel to the package top layer. Instead, as shown in FIG. 5A, the Hall sensor's integrated circuit detects magnetic fields that extend perpendicular to the package top layer. In FIG. 5A, the Hall sensor 510 has a package top layer 512 positioned opposite a magnet 520A that generates a magnetic field with magnetic flux lines 522A that extend perpendicular to the sensor's top layer 512. Therefore, the sensor 510 can detect the perpendicular magnetic field of the magnet 520A when moved sufficiently close to the sensor 510. In FIG. 5B, the package top layer 512 of the Hall sensor 510 is positioned opposite a magnet 520B that generates a magnetic field with magnetic flux lines 522B that extend parallel to the sensor's top layer 512. Therefore, the sensor 510 cannot detect the parallel magnetic field of the magnet 520B, even when the sensor 510 is in close proximity to the sensor. In one or more embodiments, this basic principle is used to determine the proper placement and orientation of magnets and sensors within a computing device to lock the computing device and to avoid additional magnets required to detect the location status of the computing device.

[0043] FIGS. 6A and 6B illustrate various possible shapes of magnets that may be used in the improved locking and position status detection scheme disclosed herein. The magnets in one or more embodiments may be of different shapes, such as disks, bars, and / or cylinders. The distribution of the magnet's magnetic field may be either axial or diametric. FIG. 6A is an example of an axially magnetized disk-shaped magnet, FIG. 6B is an example of an axially magnetized cylindrical magnet, FIG. 6C is an example of a diametrically magnetized disk-shaped magnet, and FIG. 6D is an example of a diametrically magnetized cylindrical magnet. While the embodiments of FIGS. 3 and 4A and 4B are shown and described using an axially magnetized disk magnet (i.e., 314) and an axially magnetized bar magnet (i.e., 324), it should be understood that any other shaped magnet, such as the magnets shown in FIGS. 6A through 6D or other magnets, may be used in the improved locking and position status detection scheme. Certain shapes and magnetizations may require changes to the orientation or position of the magnets within the lid and base members to ensure that the sensor (e.g., 326) does not falsely detect a closed position status from the base magnet, and to ensure that the lid and base members are magnetically held together by the lid and base magnets when the laptop is in the closed position.

[0044] 7 is a high-level flowchart 700 illustrating exemplary operations and techniques that may be performed in an electronic device incorporating the improved lock and location status detection scheme as disclosed herein. In one example, the operations and techniques of the flowchart may be performed in an electronic device such as a laptop computer 300.

[0045] For example, at 702, a magnetic field generated by a first magnet included in a first member of an electronic device can be detected by a sensor included in a second member of the electronic device. This can occur when the space between the first magnet and the sensor is reduced when the first member is moved or moved toward the second member (or vice versa). In the laptop example, this detection can occur when the lid member (e.g., 310) of the laptop is closed by rotating the lid member toward the base member (e.g., 320) of the laptop (or vice versa) about a hinge (e.g., 305) that rotatably connects the opposing ends of the lid member and base member.

[0046] At 704, the sensor may send a signal to a processor of the electronic device in response to detecting the magnetic field of the first magnet. The signal may indicate the positional status of the components of the electronic device relative to one another. In the example of a laptop, the signal may indicate that the electronic device is in a closed position in which the inner surface (e.g., 311) of the lid member is substantially adjacent to and parallel to the top surface (e.g., 321) of the base member.

[0047] At 706, a processor of the electronic device may perform an action based on receiving a position status signal from the sensor indicating that the electronic device is in a closed position. In the laptop example, the signal may indicate that the electronic device is closed and therefore the processor may initiate a sleep state of the laptop upon receiving the signal.

[0048] At 708, a first magnet in the first member engages with a second magnet in the second member, magnetically holding the first member relative to the second member with the opposing surfaces of the members aligned substantially parallel. The first and second magnets may be attracted to each other and engage when the space between them decreases as the first member is moved toward the second member (or vice versa). In the example of a laptop, this attraction and engagement may result from the laptop's lid member being rotated toward the laptop's base member (or vice versa) about a hinge that rotatably connects the lid member and base member. When the electronic device is closed and the inner surface of the lid member is substantially adjacent to and parallel to the top surface of the base member, the first magnet (e.g., 314) may have one pole (e.g., south pole) that opposes the opposing pole (e.g., north pole) of the second magnet (e.g., 324).

[0049] At 710, the electronic device may remain locked, and the operation performed at 706 may continue to be performed until the location status of the electronic device changes. Generally, if the location status changes, the sensor will send another signal to the processor of the electronic device (or avoid sending a signal, depending on the particular configuration of the sensor).

[0050] At 712, in the absence of a magnetic field generated by a first magnet included in a first member of the electronic device, a sensor included in a second member of the electronic device may stop outputting a signal to the processor. In other sensor configurations, the absence of a magnetic field may cause the sensor to output a different signal to the processor. The absence of a magnetic field generated by the first magnet may occur when the space between the first magnet and the sensor increases when the first member is moved or displaced away from the second member (or vice versa). In the laptop example, this may occur when the lid member is opened by rotating one end of the laptop lid member away from the opposing end of the laptop base member (or vice versa) about a hinge that rotatably connects the other opposing ends of the lid member and base member.

[0051] At 714, the sensor transmits a new position status signal (or avoids transmitting a position status signal) to the processor of the electronic device in response to detecting the absence of a magnetic field from the first magnet. The new position status signal (or its absence) may indicate the position status of the components of the electronic device relative to each other. In the laptop example, the new position status signal (or its absence) may indicate that the electronic device is in an open position where the lid member and base member define an angle that sufficiently separates the first magnet and sensor to prevent the sensor from detecting the magnetic field generated by the first magnet.

[0052] At 716, a processor of the electronic device may perform an action based on detecting the absence of a signal or receiving a new position status signal from the sensor indicating that the electronic device is in the open position. In the laptop example, if a new position status signal (or its absence) is detected, the processor may initiate an operating state of the laptop.

[0053] At 718, the magnetic engagement between the first magnet included in the first member and the second magnet included in the second member is broken. This may occur when the first member is moved or caused to move away from the second member (or vice versa), increasing the space between the first and second magnets. In the laptop example, the disengagement between the magnets may result from one end of the laptop's lid member being rotated away from the opposing end of the laptop's base member (or vice versa) about a hinge that rotatably connects the other opposing ends of the lid member and base member.

[0054] The teachings herein may generally be applied to any device, system, or apparatus in which there is an internal or external first member that is attached, locked, or otherwise held adjacent to another member when in a specific position, and in which detection of this position (and optionally, differentiation between multiple positions) is desired. In one non-limiting example shown in FIGS. 8A through 8C , these teachings may be extended to dual display devices that generally use external accessories such as keyboards. User experience research has shown that keyboards facilitate greater productivity compared to touchscreen-based typing because they provide better typing feedback. Thus, generally, dual display devices may have an attachment point for attaching an external keyboard on the secondary display screen of the dual display device. In at least one embodiment, the external keyboard should be securely attached to the secondary display screen, and the position of the external keyboard on the secondary display screen should be detected and identified to switch the secondary display screen to the appropriate configuration.

[0055] 8A-8C are schematic diagrams of a dual display computer 800 implementing a lock and position status detection scheme for an external accessory 830 (e.g., a keyboard), according to an embodiment. FIG. 8A is a schematic plan view of the dual display computer 800 without any external accessories attached. The dual display computer 800 includes a first display member 810 connected to a second display member 820. The connection between the first and second display members may allow them to rotatably move relative to one another about or around an axis. The axis may be defined by a connection point 805 in the form of a hinge that rotatably connects one end (e.g., a bottom or south end) of the first display member 810 to one end (e.g., a top or north end) of the second display member 820.

[0056] The first display member 810 may include a primary display screen 818 visible through a top surface 811 of the first display member 810 and may also include a first bezel region 812 that partially or completely surrounds the primary display screen 818. The first bezel region 812 may be defined between an edge of the primary display screen and an outer perimeter of the first display member. The second display member 820 may include a secondary display screen 828 visible through a top surface 821 of the second display member 820 and may also include a second bezel region 822 that partially or completely surrounds the secondary display screen 828. The bezel region 822 may be defined between an edge of the secondary display screen and an outer perimeter of the second display member. In one example, the top surface 821 may be a glass cover, a tempered glass cover, or any other suitable material that allows the secondary display screen 828 to be seen and that may optionally be used to implement touchscreen functionality. The top surface 821 may be a single surface that extends across the bezel region and the secondary display screen. Alternatively, the top surface 821 may include a combination of two or more separate surfaces. For example, the bezel region may have one surface of any suitable material, and the secondary display screen may have a separate surface of any suitable material. The interior surface 811 of the first display member 310 may be similarly configured.

[0057] In at least one embodiment of a dual-display computer, a plurality of display member magnets and corresponding sensors are included in a bezel region of one of the display members. In the example shown in FIG. 8A , display member magnets 824A, 824B, and 824C and respective sensors 826A, 826B, and 826C are disposed in a bezel region 822 on the left (or west) side of the second display member 820, and display member magnets 824D, 824E, and 824F and respective sensors 826D, 826E, and 826F are disposed in a bezel region 822 on the right (or east) side of the second display member 820. In at least one embodiment, the sensor and display member magnet pairs in the second display member 820 may have the same or similar configuration, position, and / or orientation as the sensor 326 and base magnet 324 in the base member 320 of the laptop computer 300 shown in FIGS. 3 and 4A and 4B .

[0058] 8B-8C are schematic plan views of a dual display computer 800 having an external accessory 830 attached to the second display member 820. In one example, the external accessory 830 is a keyboard. However, in other embodiments, the external accessory 830 may be any other desired accessory, such as, for example, a touchpad, a combination keyboard and touchpad, a tertiary display screen, or any other suitable accessory that may be utilized in multiple locations on a member of the computing device.

[0059] Position status detection of the external accessory 830 may be achieved using magnets and sensors (e.g., Hall sensors). In a conventional approach, an array of magnets and Hall sensors may be used to achieve detection of an external keyboard. In a conventional approach using a lock and position status detection scheme, a first set of magnets in the external accessory may be used for sensors in the second display screen to detect the position status of the external accessory. In addition, a second set of magnets in the external accessory may be used to attach a set of magnets in the second display screen to magnetically hold the external accessory to the second display screen.

[0060] However, the locking and detection scheme described herein can reduce the number of magnets required on the external keyboard (or other accessory) by half. For example, depending on the location of external accessory 830 (e.g., north / above secondary display screen 828 or south / below secondary display screen 828), accessory magnets 834A, 834B, 834C, and 834D can be included on the external accessory in positions that align with respective magnet and sensor pairs included in bezel region 822 of second display member 820. This can not only help simplify the device, but can also reduce magnetic interference with audio, RF antennas, etc., because there are fewer magnets compared to conventional implementations.

[0061] In at least one embodiment, the external accessory 830 should be magnetically coupled to or held to the second display member 820 in one or more positions. For example, the external accessory 830 may be movable longitudinally relative to the second display member 820 between the top (north) and bottom (south) ends of the second display member. Magnets in the external accessory (e.g., 834A-834D) and the magnets in the second display member (e.g., 824A-824F) can align and engage to magnetically hold the external accessory to the second display member in one or more positions.

[0062] The positional status of the external accessory 830 relative to the second display member 820 should be detected and identified to switch the secondary display screen 828 to an appropriate configuration based on the positional status of the external accessory. The external accessory 830 may include multiple magnets for forming magnetic couplings to display member magnets in the second display member 820. For example, accessory magnets 834A and 834B may be located on the left (or west) side of the external accessory 830, and accessory magnets 834C and 834D may be located on the right (or east) side of the external accessory 830. The accessory magnets 834A and 834B are spaced to align with adjacent pairs of display member magnets and sensors in the left bezel region 822 of the second display member 820 depending on the position of the external accessory 830. Similarly, accessory magnets 834C and 834D are spaced to align with adjacent pairs of display member magnets and sensors in right bezel region 822 of second display member 820, depending on the position of external accessory 830. In at least one embodiment, accessory magnets 834A-834D may have the same or similar configuration, position and / or orientation as lid magnet 314 in lid member 310 of laptop computer 300 shown in Figures 3 and 4A-4B.

[0063] In FIG. 8B , external accessory 830 is positioned substantially adjacent to and parallel to the lower (or south) side of secondary display screen 828. This arrangement leaves an upper exposed portion of secondary display screen 828 (e.g., north of the secondary display screen). In at least one embodiment, the upper exposed portion can be transitioned by the processor of dual display computer 800 to function as a small secondary display screen 828A, with data provided for display by the processor. This prevents data from being displayed on the lower portion of the secondary display screen that is covered by the external accessory. In at least one embodiment, the accessory magnets trigger respective sensors and engage respective display member magnets to magnetically lock or hold the external accessory in the lower position shown in FIG. 8B . For example, accessory magnets 834A and 834B can trigger sensors 826B and 826C, respectively, and engage display member magnets 824B and 824C, respectively, to magnetically lock or hold the external accessory in the lower position. Similarly, accessory magnets 834C and 834D may trigger sensors 826E and 826F, respectively, to engage display member magnets 824E and 824F, respectively, to magnetically lock or hold the external accessory in the lowered position.

[0064] In FIG. 8C , external accessory 830 is positioned substantially adjacent to and parallel to the top (or north) side of secondary display screen 828. This arrangement leaves a lower exposed portion of secondary display screen 828 (e.g., on the south side of the secondary display screen). In at least one embodiment, the lower exposed portion can transition to become touchpad 828B, optionally having one or two miniature screens adjacent to the touchpad. In at least one embodiment, accessory magnets trigger respective sensors and engage respective display member magnets to magnetically lock or hold the external accessory in the upper position shown in FIG. 8C . For example, accessory magnets 834A and 834B can trigger sensors 826A and 826B, respectively, and engage display member magnets 824A and 824B, respectively, to magnetically lock or hold the external accessory in the upper position. Similarly, accessory magnets 834C and 834D may trigger sensors 826D and 826E, respectively, to engage display member magnets 824D and 824E, respectively, to magnetically lock or hold the external accessory in the upper position.

[0065] The particular combination of sensors that detect the accessory magnet may determine how the processor transitions the secondary display screen 828 for use. For example, if the four sensors (e.g., 826A, 826B, 826D, and 826E) closest to the top (north) edge of the second display member 820 each detect an accessory magnet, the secondary display screen 828 may transition to touchpad 828B, optionally with adjacent screens. If the four sensors (e.g., 826B, 826C, 826E, and 826F) closest to the bottom (south) edge of the second display member 820 each detect an accessory magnet, the secondary display screen 828 may transition to small secondary display screen 828A. However, it will be apparent that any other suitable alternative uses may be configured for the exposed portion of the secondary display screen 828 when external accessories are used, and that the embodiments described herein are intended as non-limiting examples for illustrative purposes.

[0066] 9A is a schematic left (west) side view of second display member 820 of dual display computer 800 with no external accessories attached, according to at least one embodiment. Display member magnets 824A-824C are included in second display member 820 with sensors 826A-826C disposed over at least a portion of each display member magnet 824A-824C. When no external accessories are attached to dual display computer 800, external accessory magnets 834A-834D are not aligned with any sensors (e.g., 826A, 826B, 826C, 826D, 826E, 826F) in the second display member. In at least one embodiment, sensors 826A-826C can be configured to detect magnetic fields with flux lines perpendicular to the sensors' detection mechanisms. In one example, sensors 826A-826C can be implemented as Hall sensors. However, any other sensor or switch that detects a magnetic field and generates an output signal in response to the detection (or lack thereof) may be used.

[0067] In embodiments, sensors 826A-826C may be configured with top layers 827A-827C. Top layers 827A-827C detect magnetic fields extending perpendicularly thereto. Each of sensors 826A-826C may be oriented such that top layers 827A-827C are at least substantially parallel to top surface 821 of second display member 820, and thus substantially parallel to the bottom surface of the external accessory member, when external accessory 830 is magnetically coupled to the second display member. The configuration and orientation of display member magnets 824A-824C may be selected to generate magnetic fields with flux lines 825A-825C that are generally parallel to, but not perpendicular to, the sensor's detection mechanism (e.g., top layers 827A-827C). Thus, display member magnets 824A-824C may be oriented to prevent respective adjacent sensors 826A-826C from detecting magnetic fields.

[0068] In one example, display member magnet 824A can be an axially magnetized bar magnet oriented longitudinally within second display member 820 to generate a magnetic field with flux lines 825A generally parallel to top layer 827A of sensor 826A. Thus, sensor 826A is not triggered by the magnetic field of display member magnet 824A. Furthermore, display member magnet 824A can be positioned such that its north pole (N) is adjacent to but below sensor 826A. This allows a single accessory magnet (e.g., 834A) to function as a trigger for sensor 826A and magnetically engage display member magnet 824A. The other display member magnets 824B and 824C shown in FIGS. 9A-9C can be similarly configured and positioned on the left (or west) side of bezel region 822 of second display member 820. Although not shown in Figures 9A to 9C, additional display member magnets 824D-824F may be similarly configured and positioned within the bezel region 822 on the opposite (e.g., right or east) side of the second display member 820.

[0069] 9B is a schematic side view of external accessory 830 and second display member 820 of dual display computer 800 when the external accessory is in a first (e.g., lower) position. In the lower position, a bottom surface 831 of external accessory 830 faces a lower portion of top surface 821 of second display member 820 and is at least substantially parallel to and adjacent to the lower portion of the top surface of the second display member. In at least some embodiments, when the external accessory is magnetically engaged with the second display member in the lower position, bottom surface 831 abuts the lower portion of top surface 821. In other embodiments, when the external accessory is magnetically engaged with the second display member in the lower position (e.g., when ridges / recesses on the left and right edges of either the external accessory or the second display member are provided to guide longitudinal movement of the external accessory), bottom surface 831 may be separated from the lower portion of top surface 821 by a small distance. An adjacent accessory magnet on the left (or west) side of external accessory 830 is positioned to align with an adjacent sensor and display member magnet pair on the left (or west) side of second display member 820. Thus, when the external accessory is in the down position as shown in FIG. 9B , accessory magnet 834A is aligned with sensor 826B and a portion (e.g., north pole) of display member magnet 824B such that sensor 826B is positioned between accessory magnet 834A and a portion (e.g., north pole) of display member magnet 824B. Accessory magnet 834B is aligned with sensor 826C and a portion (e.g., north pole) of display member magnet 824C such that sensor 826C is positioned between accessory magnet 834B and a portion (e.g., north pole) of display member magnet 824C.

[0070] Accessory magnets 834A and 834B are further constructed and arranged to generate magnetic fields having flux lines 835A and 835B, respectively, that are perpendicular to bottom surface 831 of external accessory 830. Thus, when the external accessory is in the lower position, these magnetic fields extend perpendicularly to upper layers 827B and 827C of sensors 826B and 826C, respectively. For example, accessory magnet 834A includes a north pole (N) and a south pole (S), with its south pole (S) oriented to align with and face toward sensor 826B when the external accessory is in the lower position. Similarly, accessory magnet 834B includes a north pole (N) and a south pole (S), with its south pole (S) oriented to align with and face toward sensor 826C when the external accessory is in the lower position.

[0071] When the external accessory is in the lower position as shown in FIG. 9B , the south poles (S) of accessory magnets 834A and 834B and the north poles (N) of display member magnets 824B and 824C engage at 840A and 840B, respectively, magnetically holding the external accessory and second display member together in substantially parallel alignment. Thus, the external accessory may remain in the lower position until an appropriate amount of force is applied to separate the magnets by sliding the external accessory longitudinally (or, e.g., vertically, if the external accessory is to be removed from the dual-display computer). It will be apparent that accessory magnets 834C and 834D (not shown in FIG. 9B ) on the right (or east) side of external accessory 830 may be similarly positioned for interaction with sensors 826E and 826F and adjacent display member magnets 824E and 824F, respectively.

[0072] 9B , when the external accessory is in the lower position, sensor 826B detects the magnetic field of accessory magnet 834A, and sensor 826C detects the magnetic field of accessory magnet 834B. Sensors 826B and 826C (and 826E and 826F, not shown) may provide position status signals to the processor of dual display computer 800 to indicate that the external accessory is in the lower position. If the external accessory is moved away from the lower position, sensors 826B and 826C (and 826E and 826F, not shown) may no longer detect the magnetic field of the appropriate accessory magnet, indicating that the accessory is in the lower position. In at least one embodiment, sensors 826B and 826C (and 826E and 826F, not shown) may stop sending position status signals to the processor as an indication that the external accessory is not in the lower position. In some cases, the processor can use the position status signal from a particular combination of sensors 826B and 826C (and 826E and 826F, not shown) and / or the absence of a position status signal to determine the appropriate action to take. In one exemplary scenario, receiving a position status signal from the combination of sensors 826B, 826C, 826E, and 826F indicates that the external accessory is in the lowered position. Thus, the processor can cause the upper exposed portion of the secondary display screen to operate as a smaller secondary display screen 828A.

[0073] 9C is a schematic side view of external accessory 830 and second display member 820 of dual display computer 800 when the external accessory is in a second (e.g., upper) position. In the upper position, a bottom surface 831 of external accessory 830 faces an upper portion of top surface 821 of second display member 820 and is at least substantially parallel to and adjacent to the upper portion of the top surface of the second display member. In at least some embodiments, when the external accessory is magnetically engaged with the second display member in the upper position, bottom surface 831 abuts the upper portion of top surface 821. In other embodiments, when the external accessory is magnetically engaged with the second display member in the upper position (e.g., when ridges / recesses on the left and right edges of either the external accessory or the second display member are provided to guide longitudinal movement of the external accessory), bottom surface 831 may be separated from the upper portion of top surface 821 by a small distance. 9C, when the external accessory is in the upper position, accessory magnet 834A is aligned with sensor 826A and a portion (e.g., north pole) of display member magnet 824A such that sensor 826A is positioned between accessory magnet 834A and a portion (e.g., north pole) of display member magnet 824A. Accessory magnet 834B is aligned with sensor 826B and a portion (e.g., north pole) of display member magnet 824B such that sensor 826B is positioned between accessory magnet 834B and a portion (e.g., north pole) of display member magnet 824B.

[0074] When the external accessory is in the lower position, the magnetic fields of accessory magnets 834A and 834B extend perpendicularly to the upper layers 827A and 827B of sensors 826A and 826B, respectively. In this example, accessory magnet 834A is oriented with its south pole (S) aligned with and facing toward sensor 826A when the external accessory is in the upper position. Similarly, accessory magnet 834B is oriented with its south pole (S) aligned with and facing toward sensor 826B when the external accessory is in the upper position.

[0075] When the external accessory is in the upper position as shown in FIG. 9C , the south poles (S) of accessory magnets 834A and 834B and the north poles (N) of display member magnets 824A and 824B engage at 842A and 842B, respectively, magnetically holding the external accessory and second display member together in substantially parallel alignment. Thus, the external accessory may remain in the upper position until an appropriate amount of force is applied to separate the magnets by sliding the external accessory longitudinally (or, e.g., vertically, if the external accessory is to be removed from the dual-display computer). It will be apparent that accessory magnets 834C and 834D (not shown in FIG. 9C ) on the right (or east) side of external accessory 830 may be similarly positioned for interaction with sensors 826D and 826E and adjacent display member magnets 824D and 824E, respectively.

[0076] 9C , when the external accessory is in the upper position, sensor 826A detects the magnetic field of accessory magnet 834A, and sensor 826B detects the magnetic field of accessory magnet 834B. Sensors 826A and 826B (and 826D and 826E, not shown) may provide position status signals to the processor of dual display computer 800 to indicate that the external accessory is in the upper position. If the external accessory is moved away from the upper position, sensors 826A and 826B (and 826D and 826E, not shown) may no longer detect the magnetic field of the appropriate accessory magnet, indicating that the external accessory is in the upper position. In at least one embodiment, sensors 826A and 826B (and 826D and 826E, not shown) may stop sending position status signals to the processor as an indication that the external accessory is not in the upper position. In some cases, the processor can use the position status signal from a particular combination of sensors 826A and 826B (and 826D and 826E, not shown) and / or the absence of a position status signal to determine the appropriate action to take. In one exemplary scenario, receiving a position status signal from the combination of sensors 826A, 826B, 826D, and 826E indicates that the accessory is in the upper position. Thus, the processor can operate the lower exposed portion of the secondary display screen as a touchpad, as a touchpad and adjacent screen 828B, as a miniature screen, or any other suitable alternative use.

[0077] It will be apparent that the non-limiting illustrations and examples provided herein may be modified or varied in any number of ways. For example, more or fewer display member magnets with corresponding sensor and accessory magnets may be provided in appropriate locations to allow any suitable external accessory to be magnetically coupled to the display member at one, two, or more different locations. Furthermore, it will be apparent that the embodiments described herein may be combined in any suitable manner. For example, a lid magnet (e.g., 314) may be used in a dual display device (e.g., 800) to bring the device closer when an external accessory (e.g., 830) is removed. The lid magnet may be positioned to align with any of the second display member magnets (e.g., 824A-824F) and corresponding sensors (e.g., 826A-826F).

[0078] As used herein, the terms "contained" and "disposed" in reference to an object being contained within or by, or disposed within, another object, are intended to mean that the one object (e.g., lid magnet 314, base magnet 324, sensor 326, second display member magnets 824A-824F, sensors 826A-826F, accessory magnets 834A-834D, etc.) may be embedded in, integrated with, affixed to, attached to, connected to, or otherwise contained within the other object (e.g., lid member 310, base member 320, first display member 810, second display member 820, external accessory 830, etc.).

[0079] 10 and 11 are block diagrams of exemplary computer architectures that may be connected to, embedded in, or otherwise interoperate with lock and location status detection schemes according to embodiments disclosed herein. Other computer architecture designs known in the art for processors and computing systems may also be used. In general, computer architectures suitable for embodiments disclosed herein may include, but are not limited to, the configurations shown in FIGS. 10 and 11.

[0080] FIG. 10 is an exemplary diagram of a processor according to an embodiment. Processor 1000 is an example of a type of hardware device (e.g., a processor in laptop computer 300, a processor in dual-display computer 800) that may be used in connection with the implementations shown and described herein above. Processor 1000 may be any type of processor, such as a microprocessor, an embedded processor, a digital signal processor (DSP), a network processor, a multi-core processor, a single-core processor, or other device for executing code. Although only one processor 1000 is shown in FIG. 10, a processing element may alternatively include more than one processor 1000 as shown in FIG. 10. Processor 1000 may be a single-threaded core, or, in at least one embodiment, processor 1000 may be multi-threaded in that it may include more than one hardware thread context (or logical processor) per core.

[0081] 10 also illustrates memory 1002 coupled to processor 1000 according to an embodiment. Memory 1002 may be any of a wide variety of memories (including various layers of a memory hierarchy) known or otherwise available to those skilled in the art. Such memory elements may include, but are not limited to, random access memory (RAM), read-only memory (ROM), logic blocks of a field programmable gate array (FPGA), erasable programmable read-only memory (EPROM), and electrically erasable programmable ROM (EEPROM).

[0082] The processor 1000 can execute any type of instruction related to an algorithm, process, or operation described herein. Generally, the processor 1000 can transform elements or items (e.g., data) from one state or thing to another state or thing.

[0083] Code 1004, which may be one or more instructions executed by processor 1000, may be stored in memory 1002, or may be stored in software, hardware, firmware, or any suitable combination thereof, or in any other internal or external component, device, element, or object, if appropriate, based on particular needs. In one example, processor 1000 may follow a program sequence of instructions indicated by code 1004. Each instruction enters front-end logic 1006 and is processed by one or more decoders 1008. The decoders may generate as output micro-operations, such as fixed-width micro-operations in a predefined format, or may generate other instructions, micro-instructions, or control signals that reflect the original code instruction. Front-end logic 1006 also includes register renaming logic 1010 and scheduling logic 1012. These logics generally allocate resources and queue operations corresponding to instructions for execution.

[0084] Processor 1000 may also include execution logic 1014 having a set of execution units 1016a, 1016b, 1016n, etc. Some embodiments may include many execution units dedicated to a particular function or set of functions. Other embodiments may include only one execution unit or one execution unit capable of performing a particular function. Execution logic 1014 performs operations specified by code instructions.

[0085] After completing execution of the operation specified by the code instruction, the back-end logic 1018 can retire the instruction of the code 1004. In one embodiment, the processor 1000 allows out-of-order execution but requires in-order retirement of instructions. The retirement logic 1020 may take various known forms (e.g., a reorder buffer, etc.). In this manner, the processor 1000 is transformed during execution of the code 1004 with respect to at least the outputs generated by the decoders, hardware registers and tables utilized by the register renaming logic 1010, and any registers (not shown) modified by the execution logic 1014.

[0086] 10, a processing element may include other elements on a chip with processor 1000. For example, a processing element may include memory control logic along with processor 1000. A processing element may include I / O control logic and / or may include I / O control logic integrated with memory control logic. A processing element may also include one or more caches. In some embodiments, non-volatile memory (such as flash memory or fuses) may also be included on a chip with processor 1000.

[0087] In an exemplary implementation, processor 1000 may be used in conjunction with a processor of laptop computer 300 and may be operably connected to sensors 314 for receiving position status signals indicating whether the lid is in the open or closed position. Code 1004 may be executed to identify whether the signal indicates whether the lid is in the open or closed position and to control the state of the laptop computer. For example, the laptop computer may be transitioned to an active state that allows user interaction (e.g., when the lid is open) or to a sleep state where applications are not active and power is conserved (e.g., when the lid is closed). In another example, processor 1000 may be used in conjunction with a processor of laptop computer 800 and may be operably connected to sensors 826A-826F for receiving position status signals. A combination of signals (or the absence of signals) from a particular group of sensors indicates the position of external accessory 830. Code 1004 may be executed to identify which combination of sensors generated the set of received signals and to identify the location of the external accessory based on the identified combination of sensors. Code 1004 may also be executed to control the state or configuration of second display screen 828 and cause it to transition according to the identified location of the external accessory. In other examples, hardware, firmware, or any combination of hardware, firmware, and code 1004 of processor 1000 may be used to perform these operations.

[0088] 11 illustrates a computing system 1100 arranged in a point-to-point (PtP) configuration according to an embodiment. In particular, FIG. 11 illustrates a system in which a processor, memory, and input / output devices are interconnected by a number of point-to-point interfaces.
