DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
The following detailed description sets forth example embodiments of apparatuses, methods, and systems relating to keyboard protection configurations for an electronic device. Features such as structure(s), function(s), and/or characteristic(s), for example, are described with reference to one embodiment as a matter of convenience; various embodiments may be implemented with any suitable one or more of the described features.
FIG. 1A is a simplified orthographic view illustrating an embodiment of an electronic device 10a in an open clamshell configuration in accordance with one embodiment of the present disclosure. Electronic device 10a may include a display portion 12 and a keyboard portion 14a. Display portion 12 may include a display 16. Keyboard portion 14a may include a keyboard 18. In an embodiment, display portion 12 and keyboard portion 14a can have about the same XY footprint (i.e., about the same length and about the same width). Display portion 12 can be removably connected to keyboard portion 14a in a first configuration (e.g., a clamshell configuration), where a viewing angle of the display portion can be adjusted. In addition, display portion 12 can be removably connected to keyboard portion 14a in a second configuration (e.g., a tablet configuration). In addition, when electronic device 10a is in the open clamshell configuration, display portion 12 may be located away from an edge 70 of keyboard portion 14a and towards a center portion 72 of keyboard portion 14a to allow the center of mass of electronic device 10a to be closer to center portion 72 and mitigate against tipping of electronic device 10a. 
In one or more embodiments, electronic device 10a may be any suitable electronic device having a display such as a mobile device, a tablet computer and/or a tablet device (e.g., i-Pad), a personal digital assistant (PDA), a smartphone, an audio system, a movie player of any type, a computer docking station, etc. Display 16 may be a liquid crystal display (LCD), organic light-emitting diode (OLED), or some other type of display. Electronic device 10a can contain a battery and various electronics (e.g., wireless module (e.g., Wi-Fi module, Bluetooth module, etc.) processor, memory, camera, a microphone, speakers, etc.) to allow electronic device to operate.
Turning to FIG. 1B, FIG. 1B is a simplified orthographic view illustrating electronic device 10a in a detached configuration, separated into two segments in accordance with one embodiment of the present disclosure. Display portion 12 and keyboard portion 14a may be connected by a cradle dock 20. Cradle dock 20 may be located away from edge 70 and towards center portion 72 so that when display portion 12 is connected to keyboard portion and electronic device 10a is in the open clamshell configuration, the center of mass of electronic device 10a is closer to center portion 72 and thus can mitigate tipping of electronic device 10a. Cradle dock 20 can define an axis of rotation (or multiple axes of rotation) that is shared between display portion 12 and keyboard portion 14a. Cradle dock 20 may include a printed circuit board (PCB) interconnector.
Using cradle dock 20, an electrical current and signals can be passed between display portion 12 and keyboard portion 14a to recharge an on-board battery or capacitor, power any number of items (e.g., display 16, a wireless module, a camera, speakers, etc.), and provide a communication path between display portion 12 and keyboard portion 14a. In other examples, electrical current and signals can be passed through a plug-in connector (e.g., whose male side protrusion connects to display portion 12 and whose female side connects to keyboard portion 14a or vice-verse) or a wireless connector (e.g., Wi-Fi, Bluetooth, etc.). Note that any number of connectors (e.g., Universal Serial Bus (USB) connectors (e.g., in compliance with the USB 3.0 Specification released in November 2008), ThunderboltTM connectors, a non-standard connection point such as a docking connector, etc.) can be provisioned in conjunction with electronic device 10a. [ThunderboltTM and the Thunderbolt logo are trademarks of Intel Corporation in the U.S. and/or other countries.]. Virtually any other electrical connection methods could be used and, thus, are clearly within the scope of the present disclosure.
Turning to FIG. 1C, FIG. 1C is a simplified orthographic view illustrating display portion 12 being placed on keyboard portion 14a in accordance with one embodiment of the present disclosure. In FIG. 1C, display 16 (not shown) is facing keyboard 18. Turning to FIG. 1D, FIG. 1D is a simplified orthographic view illustrating an embodiment of an electronic device 10a in a closed clamshell configuration. As illustrated in FIG. 1D, the XY footprint (or size) of display portion 12 is the same (or about the same) as keyboard portion 14a such that a portion of display portion 12 (or a portion of keyboard portion 14a) does not extend (or slightly extends) past an edge of keyboard portion 14a (or of display portion 12).
Turning to FIG. 1E, FIG. 1E is a simplified orthographic view illustrating display portion 12 being placed on keyboard portion 14a in accordance with one embodiment of the present disclosure. As illustrated in FIG. 1E, display 16 is facing away from keyboard 18. Turning to FIG. 1F, FIG. 1F is a simplified orthographic view illustrating an embodiment of an electronic device 10a in a tablet configuration. As illustrated in FIG. 1F, the XY footprint (or size) of display portion 12 is the same (or about the same) as keyboard portion 14a such that a portion of display portion 12 (or a portion of keyboard portion 14a) does not extend (or slightly extends) past an edge of keyboard portion 14a (or of display portion 12).
The following information may be viewed as a basis from which one or more embodiments may be explained. Although the embodiments described are related to laptops, tablets, convertible laptops, hybrid laptops, etc. there may be other embodiments that deal with phone, PDAs, audio systems, etc. A hybrid laptop, (e.g., a convertible computer, etc.) is a mobile computer that can include a clamshell or laptop configuration (illustrated in FIGS. 1A and 1D) and a tablet configuration (illustrated in FIG. 1F). To convert from the clamshell configuration to the tablet configuration, often the display or screen (e.g., display portion 12) can be separated from a base or a keyboard (e.g., keyboard portion 14a). While hybrid laptops are a compelling way of delivering convertibility from a clamshell configuration to a tablet configuration, in some designs, when the device is in an open clamshell configuration, the device is top heavy. This is because once detached, the display is a fully functioning tablet which necessitates that most of the electronics are in the display, leaving little system mass under the base. The fact that the device is top heavy makes the device susceptible to tip over while in an open clamshell configuration and many devices today are extremely unstable when using touchscreen functions, especially when using the device on an uneven surface such as a lap of a user. To remedy the problem of tipping, some devices have a larger base than the display. Unfortunately, this can make hybrid laptops undesirable to some users when the hybrid laptop is in a closed clamshell configuration as the base sticks out from an edge or edges of the display. Also, the detachable form factor can be confusing to the user because the tablet configuration can consist of two separate components and the user may be concerned about losing the base (which often includes a keyboard) or leaving the base at one location when the user is at another location.
In an embodiment, the electrical device can be configured to mitigate against tipping and allow for screen angle adjustment without compromising the XY footprint of the system or adding weight to the base of the electronic device. Electronic device can include two connection mechanisms between the display (e.g., display portion 12) and the base (e.g., keyboard portion 14a). The first connection mechanism may be a stacking connector such as magnets. The connector can allow for the display to be stacked on to and held against the base in either a tablet configuration (the display up) or a closed clamshell configuration (the display down). The configurations allow for the base to be stored behind the display when the electronic device is in a tablet configuration as well as a protected display configuration for transportation in a closed clamshell configuration. In an embodiment, a surface connector may allow for charging of the display from batteries in the base.
The second connection mechanism may be a cradle dock (e.g., cradle dock 20 or ‘docking connector’ more generally) that sits inward from a back edge (e.g., edge 70) of the base. The cradle dock may have only a back support plate (or back plate) for less total system thickness impact when compared to existing cradle docks used to achieve clamshell support. In an embodiment, the location of the cradle dock can create a “porch” or footing behind the display that stabilizes the system. The cradle dock may consist of pin inserts and a back plate to support the display in a clamshell configuration while allowing for viewing angle adjustment. When the display is undocked, the cradle dock can be receded (e.g., fully or at least substantially) into the base (i.e., the base has a flat or substantially flat profile) so that the display can be stacked or coupled to the base without interference (or with relatively little interference). The cradle dock's ability to recede may also protect connectors or interconnects from damage when the display and base are separated. A release mechanism may be activated to raise the cradle dock from a closed configuration and expose the connectors or interconnects for docking with the display. For example, when the display portion (or tablet) is lifted from the keyboard portion (or base), the cradle dock can be raised by pushing a simple button.
Note that any of the cradle docks discussed herein may be of any appropriate shape and dimensions, where its construction could reflect an integral piece (e.g., of plastic, metal, fiber, any combination of these, etc.) or its construction could reflect a number of components being fit together. The cradle dock could have various sub-parts (e.g., two sub-parts on either end of the keyboard portion or the display portion). The cradle dock could be hidden from sight, or exposed. In certain implementations, the cradle dock could extend the length of the keyboard portion or the display portion, or it could be much smaller. It is imperative to note that any such alternatives and permutations are clearly within the broad scope of the present disclosure.
Turning to FIG. 2, FIG. 2 is a simplified orthographic view illustrating electronic device 10a in accordance with one embodiment of the present disclosure. Electronic device 10a can include display portion 12 and keyboard portion 14a. Display portion 12 can include one or more stacking connectors 22 and one or more bumpers 24. Keyboard portion 14a may also include one or more stacking connectors 22 and one or more bumpers 24. In an embodiment, one or more stacking connectors 22 may be magnets. One or more stacking connectors 22 can facilitate connecting display portion 12 to keyboard portion 14a and keeping them connected together. One or more bumpers 24 may each be a rubber bumper to mitigate against scuffing from display portion 12 and keyboard portion 14a and to absorb any shock that may occur when display portion 12 and keyboard portion 14a are connected together.
In an embodiment, the attractive force between one or more stacking connectors 22 on display portion 12 and one or more stacking connectors 22 on keyboard portion 14a can be such that a relatively small amount of force is required to remove display portion 12 from keyboard portion 14a (e.g., a user can remove display portion 12 from keyboard portion 14a with one hand). One or more of stacking connectors 22 may be encased in electronic device 10a and provide a directional focus for the magnetic field created by one or more stacking connectors 22. In addition, one or more stacking connectors 22 may be accompanied by a suitable backing (e.g., a steel backing) to reduce unwanted stray magnetic fields. In a particular example implementation, rare earth magnets with alternating polarity and a steel back plate can be used to reduce stray magnetic fields and to concentrate the magnetic fields in a desired direction.
Turning to FIG. 3A, FIG. 3A is a simplified orthographic view illustrating a portion of electronic device 10a in accordance with one embodiment of the present disclosure. Electronic device 10a includes cradle dock 20 and release mechanism 26.

Turning to FIG. 4C, FIG. 4C is a simplified cut away side view illustrating an embodiment a portion of electronic device 10a in accordance with one embodiment of the present disclosure. The activation of release mechanism 26 causes cradle dock 20 to raise up (e.g., up to about ninety degrees (90°) relative to keyboard portion 14a) or rotate such that one or more connections 28 are exposed. This can allow for display portion 12 to be docked or connected to keyboard portion 14a. 
Turning to FIG. 4D, FIG. 4D is a simplified cut away side view illustrating an embodiment of a portion of electronic device 10a in accordance with one embodiment of the present disclosure. As illustrated in FIG. 4D, display portion 12 has been docked or connected to keyboard portion 14a using cradle dock 20.
