The subject matter described herein relates generally to the field of electronic devices and more particularly to portable electronic devices.
Many electronic devices utilize a “clamshell” chassis. By way of example, many laptop computers and mobile electronic devices utilize a clamshell chassis in which a keyboard is disposed on a first housing and a display is disposed on a second housing coupled to the first housing by a hinge. Alternatively, a “clamshell” can consist of displays, one on a first housing that can also be utilized as a touch keyboard and one display on a second housing coupled to the first housing by a hinge.
The advent of tablet computers has driven a market for laptop devices that are convertible between a traditional notebook and a tablet configuration. Accordingly chasses which enable an electronic device to convert between configurations may find utility.
The detailed description references the accompanying figures.
In the following description, numerous specific details are set forth to provide a thorough understanding of various examples. However, it will be understood by those skilled in the art that the various examples may be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been illustrated or described in detail so as not to obscure the particular examples.
Electronic devices such as, e.g., tablet computing devices typically provide a lackluster keyboard interface. Touch-screen keyboards have proven difficult to use and keyboards which are connectable to the electronic device present an inconvenience.
Described herein are examples of an electronic device which is convertible between a tablet configuration and a notebook configuration. In some examples the comprises a first housing and a second housing coupled to the first housing such that the second housing is rotatable about an axis that extends diagonally through portions of the first housing and the second housing. When the electronic device is in a tablet configuration the second housing is substantially parallel with and adjacent to the first housing such that the first housing and the second housing present substantially coplanar surfaces which may incorporate displays.
Rotating the second housing about the axis repositions the respective first housing and second housing such that the electronic device is in a configuration that is typical of notebook computing devices. The first housing may comprise a keyboard and in this configuration the keyboard is presented for user interaction, while the second housing presents a display.
The electronic device may comprise logic to detect whether the electronic device is in a tablet configuration or a notebook configuration and to adjust one or more operating parameters in accordance with the configuration. For example, if the logic detects that the electronic device is in a table configuration then the logic may activate displays on both the first housing and the second housing. Alternatively, if the logic detects that device is switched to a notebook configuration then the logic may deactivate the display on the first housing and activate a keyboard on the first housing.
A detailed description of examples of an electronic device will be provided below with reference to

The particular dimensions of electronic device 100 are not critical. In some examples the first housing 210 may have a width indicated by W1 that measures between about 8 inches and 16 inches, a thickness indicated by T1 that measures between about 0.25 inches and about 1.5 inches, and a depth indicated by D1 that measures between about 4 inches and about 8 inches. Similarly, the second housing 230 may have a width indicated by W2 that measures between 8 inches and 16 inches, a thickness indicated by T2 that measures between about 0.25 inches and about 1.5 inches, and a depth indicated by D2 that measures between about 4 inches and about 8 inches.
In some examples the first housing 210 and the second housing 230 are connected by a hinge assembly which enables rotational movement between the first housing 210 and the second housing 230 about axis 250.
In some examples the first annular member 310 comprises slots 312A, 312B formed in the annular member 310. In the example depicted in
In some examples the tabs 322A, 322B may comprise rounded edges such that, under application of a rotational force to the second annular member 320, the tabs 322A, 322B are driven inwardly, which disengages the tabs 322A, 322B from the slots 312A, 312B. This enables the second annular member 320 to rotate within the first annular member 310, or to be completely removed from first annular member 310. The second annular member may be rotated 180 degrees, whereupon the tabs 322A, 322B will once again engage with the slots 312A, 312B to secure the second annular member 320 within the first annular member 310.
The particular dimensions of the first annular member 310 and the second annular member 320 are not critical. In some examples the first annular member 310 is dimensioned to fit within the first housing 210 and the second annular member 320 is dimensioned to fit within the second housing 230. The first annular member 310 and the second annular member 320 may be aligned along axis 250. Referring to

If, at operation 515, the electronic device 100 is in a notebook configuration then control passes to operation 520 and the configuration logic 176 generates a signal which activates the keyboard 218 and the display 240 so that the electronic device 100 is configured in a notebook configuration.
By contrast, if at operation 515 the electronic device 100 is in a tablet configuration then control passes to operation 525 and the configuration logic 176 generates a signal which activates the display 220 and the display 240 so that the device 100 is configured in a tablet configuration.
In some examples the display 220 and display 240 may operate independently. In other examples the display 220 and the display 240 may be integrated (operation 530) when the electronic device 100 is in a tablet configuration such that the display 220 and the display 240 present as a single, integrated display. For example, configuration logic 176 may provide a signal to graphics processor(s) 124 to map graphics output to a display 240 when the electronic device 100 is in tablet configuration, and to map the graphics output to displays 220 and 240 as a single combined display when they electronic device 100 is in a tablet configuration.
As described above, in some examples the electronic device 100 may be embodied as a computer system.

The MCH 608 may also include a graphics interface 614 that communicates with a display device 616. In one example of the invention, the graphics interface 614 may communicate with the display device 616 via an accelerated graphics port (AGP). In an example of the invention, the display 616 (such as a flat panel display) may communicate with the graphics interface 614 through, for example, a signal converter that translates a digital representation of an image stored in a storage device such as video memory or system memory into display signals that are interpreted and displayed by the display 616. The display signals produced by the display device may pass through various control devices before being interpreted by and subsequently displayed on the display 616.
A hub interface 618 may allow the MCH 608 and an input/output control hub (ICH) 620 to communicate. The ICH 620 may provide an interface to I/O device(s) that communicate with the computing system 600. The ICH 620 may communicate with a bus 622 through a peripheral bridge (or controller) 624, such as a peripheral component interconnect (PCI) bridge, a universal serial bus (USB) controller, or other types of peripheral bridges or controllers. The bridge 624 may provide a data path between the CPU 602 and peripheral devices. Other types of topologies may be utilized. Also, multiple buses may communicate with the ICH 620, e.g., through multiple bridges or controllers. Moreover, other peripherals in communication with the ICH 620 may include, in various examples of the invention, integrated drive electronics (IDE) or small computer system interface (SCSI) hard drive(s), USB port(s), a keyboard, a mouse, parallel port(s), serial port(s), floppy disk drive(s), digital output support (e.g., digital video interface (DVI)), or other devices.
The bus 622 may communicate with an audio device 626, one or more disk drive(s) 628, and a network interface device 630 (which is in communication with the computer network 603). Other devices may communicate via the bus 622. Also, various components (such as the network interface device 630) may communicate with the MCH 608 in some examples of the invention. In addition, the processor 602 and one or more other components discussed herein may be combined to form a single chip (e.g., to provide a System on Chip (SOC)). Furthermore, the graphics accelerator 616 may be included within the MCH 608 in other examples of the invention.
Furthermore, the computing system 600 may include volatile and/or nonvolatile memory (or storage). For example, nonvolatile memory may include one or more of the following: read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically EPROM (EEPROM), a disk drive (e.g., 628), a floppy disk, a compact disk ROM (CD-ROM), a digital versatile disk (DVD), flash memory, a magneto-optical disk, or other types of nonvolatile machine-readable media that are capable of storing electronic data (e.g., including instructions).
In an example, the processor 702-1 may include one or more processor cores 706-1 through 706-M (referred to herein as “cores 706” or more generally as “core 706”), a shared cache 708, a router 710, and/or a processor control logic or unit 720. The processor cores 706 may be implemented on a single integrated circuit (IC) chip. Moreover, the chip may include one or more shared and/or private caches (such as cache 708), buses or interconnections (such as a bus or interconnection network 712), memory controllers, or other components.
In one example, the router 710 may be used to communicate between various components of the processor 702-1 and/or system 700. Moreover, the processor 702-1 may include more than one router 710. Furthermore, the multitude of routers 710 may be in communication to enable data routing between various components inside or outside of the processor 702-1.
The shared cache 708 may store data (e.g., including instructions) that are utilized by one or more components of the processor 702-1, such as the cores 706. For example, the shared cache 708 may locally cache data stored in a memory 714 for faster access by components of the processor 702. In an example, the cache 708 may include a mid-level cache (such as a level 2 (L2), a level 3 (L3), a level 4 (L4), or other levels of cache), a last level cache (LLC), and/or combinations thereof. Moreover, various components of the processor 702-1 may communicate with the shared cache 708 directly, through a bus (e.g., the bus 712), and/or a memory controller or hub. As shown in
As illustrated in
Additionally, the core 706 may include a schedule unit 806. The schedule unit 806 may perform various operations associated with storing decoded instructions (e.g., received from the decode unit 804) until the instructions are ready for dispatch, e.g., until all source values of a decoded instruction become available. In one example, the schedule unit 806 may schedule and/or issue (or dispatch) decoded instructions to an execution unit 808 for execution. The execution unit 808 may execute the dispatched instructions after they are decoded (e.g., by the decode unit 804) and dispatched (e.g., by the schedule unit 806). In an example, the execution unit 808 may include more than one execution unit. The execution unit 808 may also perform various arithmetic operations such as addition, subtraction, multiplication, and/or division, and may include one or more an arithmetic logic units (ALUs). In an example, a co-processor (not shown) may perform various arithmetic operations in conjunction with the execution unit 808.
Further, the execution unit 808 may execute instructions out-of-order. Hence, the processor core 706 may be an out-of-order processor core in one example. The core 706 may also include a retirement unit 810. The retirement unit 810 may retire executed instructions after they are committed. In an example, retirement of the executed instructions may result in processor state being committed from the execution of the instructions, physical registers used by the instructions being de-allocated, etc.
The core 706 may also include a bus unit 714 to enable communication between components of the processor core 706 and other components (such as the components discussed with reference to

The chipset 1020 may communicate with a bus 1040 using a PtP interface circuit 1041. The bus 1040 may have one or more devices that communicate with it, such as a bus bridge 1042 and I/O devices 1043. Via a bus 1044, the bus bridge 1043 may communicate with other devices such as a keyboard/mouse 1045, communication devices 1046 (such as modems, network interface devices, or other communication devices that may communicate with the computer network 1003), audio I/O device, and/or a data storage device 1048. The data storage device 1048 (which may be a hard disk drive or a NAND flash based solid state drive) may store code 1049 that may be executed by the processors 1004.

The term “logic” as referred to herein relates to structure for performing one or more logical operations. For example, logic may comprise circuitry which provides one or more output signals based upon one or more input signals. Such circuitry may comprise a finite state machine which receives a digital input and provides a digital output, or circuitry which provides one or more analog output signals in response to one or more analog input signals. Such circuitry may be provided in an application specific integrated circuit (ASIC) or field programmable gate array (FPGA). Also, logic may comprise machine-readable instructions stored in a memory in combination with processing circuitry to execute such machine-readable instructions. However, these are merely examples of structures which may provide logic and examples are not limited in this respect.
Some of the methods described herein may be embodied as logic instructions on a computer-readable medium. When executed on a processor, the logic instructions cause a processor to be programmed as a special-purpose machine that implements the described methods. The processor, when configured by the logic instructions to execute the methods described herein, constitutes structure for performing the described methods. Alternatively, the methods described herein may be reduced to logic on, e.g., a field programmable gate array (FPGA), an application specific integrated circuit (ASIC) or the like.
In the description and claims, the terms coupled and connected, along with their derivatives, may be used. In particular examples, connected may be used to indicate that two or more elements are in direct physical or electrical contact with each other. Coupled may mean that two or more elements are in direct physical or electrical contact. However, coupled may also mean that two or more elements may not be in direct contact with each other, but yet may still cooperate or interact with each other.
Reference in the specification to “one example” or “some examples” means that a particular feature, structure, or characteristic described in connection with the example is included in at least an implementation. The appearances of the phrase “in one example” in various places in the specification may or may not be all referring to the same example.
Although examples have been described in language specific to structural features and/or methodological acts, it is to be understood that claimed subject matter may not be limited to the specific features or acts described. Rather, the specific features and acts are disclosed as sample forms of implementing the claimed subject matter.
