     DETAILED DESCRIPTION 
       [0009]    Portable devices use hardware and software that are designed for portability. A portable device is one that can be moved easily and can fall into multiple categories such as notebook, ultralight and handheld. The portable device can have batteries or another portable power source and can have hardware such as processors and displays that use less power than a non-portable counterpart to prolong the battery life of the portable device before requiring a recharge. 
         [0010]    Portable devices can have applications that can be downloaded or purchased. The applications such as games, productivity, and media applications can be used on the portable device, but cannot be easily accessed by a computing device such as a desktop computer. A user may not want to purchase different software to run on a desktop computer if the software that they want to access is on their portable device. 
         [0011]    If a portable device advertised itself to a computing device, then the computing device could display a list of applications that are on the portable device. For example if the portable device and the computing device were on the same 802.11 (Wi-Fi) network the portable device can advertise to the computing device that it is there. The computing device can determine a list of applications that are on the portable device and present an application in a graphical user interface (GUI) such as a menu or folder. The user can then access an application from the GUI which can cause the computing device to execute the application from the portable device using a hardware virtualizer that emulates the hardware of the portable device. By executing the application on the computing device from the portable device the user may have available a larger screen, more processing speed, more memory or other capabilities than are not on the portable device. 
         [0012]    In one embodiment, a computing device includes a transceiver to establish a connection to a portable device. The computing device includes a controller that can receive an advertisement from the portable device through the transceiver if the portable device is connected. The controller also can request a list from the portable device. The computing device can include a memory to store a list, received from the portable device through the transceiver, of an application formatted for the hardware of the portable device. A graphical user interface can present the list of the application to the user of the computing device. A hardware virtualizer on the computing device can execute the application on the computing device. 
         [0013]    One embodiment is a method of automatically presenting an application including a portable device that advertises itself. The portable device can be discovered with a computing device paired with the portable device. A computing device can establish a connection with the portable device. The computing device can determine an application that is available on the portable device. The computing device can present the application on the portable device in a list with a native computing device application. 
         [0014]    With reference to the figures,  FIG. 1  is a block diagram of a device according to an example embodiment of the invention. A computing device  100  can include a transceiver  120  to establish a connection to a portable device. The computing device  100  can be for example a desktop computer, a notebook computer, a tablet computer or another computing device. The transceiver  120  can be for example a wireless transceiver such as Bluetooth or WLAN such as 802.11. The transceiver may also be a wired connection such as USB, IEEE 1392, eSATA or another connection. If the transceiver  120  is a wireless transceiver then the computing device  100  may be paired with the portable device. Pairing can be the creation of a persistent link between the computing device and the portable device, which may involve the exchange of a passkey between two devices. Pairing may occur once so future connections between the devices are authenticated automatically. 
         [0015]    The computing device  100  can include a controller  105  to receive an advertisement from the portable device through the transceiver  120  if the portable device is connected through a wired connection or paired with the computing device  100 . The advertisement may be done by a service discovery protocol such as Zeroconf, that locates devices such as other computers, and the services that those devices offer on a local network using multicast Domain Name System service records. The controller  105  may be a network controller, a central processing unit or another circuit to process instructions or data. 
         [0016]    The controller  105  can send a request to the transceiver  120 . If the transceiver is connected to a portable device then the request can cause the portable device to send a list that includes at least one application or service that are stored on the portable device. The list of that application or service can be stored in a memory  145 . The memory may be a volatile or non-volatile memory, for example the memory may be random access memory (RAM), Flash memory, a hard disk drive, an optical storage or another type of memory. 
         [0017]    The application may be interpreted or static. A static application is translated into machine code before execution. For example applications written in C or C++ are static and HTML are interpreted. If the application from the portable device is static the machine code may not be executed properly on the computing device hardware and the hardware virtualizer  115  is used to execute the machine code of the static application. If the application is interpreted then it may be executed with a dynamic translator  130  such as a just-in-time (JIT) compiler on the computing device  100 . The JIT compiler can translate the application to machine readable code continuously. 
         [0018]    The list of that application received from the portable device through the transceiver  120  can be of an application formatted for the hardware of the portable device and stored on the portable device. The computing device may include a controller for example that uses a first instruction set such as X86 while the application may be formatted to execute on a controller that uses a second instruction set such as ARM. A hardware virtualizer  115  may be used to create a virtual controller with the second instruction set that executes on the controller with the first instruction set. The hardware virtualizer may be hardware or software. 
         [0019]    A graphical user interface (GUI)  135  can present the list of the application. The list may be presented to a user on a display. For example the list may include links, icons, menu items and may be presented in a folder, a task bar, on the desktop of a GUI or in other forms. 
         [0020]    If the user activates displayed presentation of the application on the list the computing device can receive the application  110  from the portable device through the transceiver  120 . The application can then be executed by the hardware virtualizer  115  or the dynamic translator  130 . The user may then see the application on the GUI  135  of the computing device  100 . 
         [0021]      FIG. 2  is a block diagram of a system according to an example embodiment of the invention. The system  201  includes a computing device  200  and a portable device  250 . The portable device  250  can be a device that can be moved easily and can fall into multiple categories such as notebook, ultralight and handheld. The portable device  250  can have batteries and can have hardware such as processors or displays that use less power than a non-portable counterpart to prolong the battery life of the portable device before requiring a recharge. 
         [0022]    The portable device  250  can include an application  210  stored on the portable device  250 . The application can be formatted to execute on the hardware of the portable device  250 . The hardware may be different than the hardware of the computing device  200 . The computing device  200  may have a native application  211  that is designed to execute on the hardware of the computing device  200 . For example the computing device may have an operating system designed to execute on the computing device  200 . The native application  211  may also be for example a word processor, spreadsheet or web browser or another application. The hardware virtualizer  215  may be run by the operating system if the application that is trying to be executed is not a native app to the hardware or operating system of the computing device  200  and is not an application that can be interpreted by a dynamic translator  230 . 
         [0023]    The portable device  250  may include a transceiver  265  to communicate data to the transceiver  220  of the computing device  200 . The transceiver  265  can send an advertisement from the advertise system  270  of the portable device to the computing device  200 . The advertisement can be received and/or discovered by the computing device  200  and processed by the controller  205 . The computing device  200  and the portable device  250  may automatically create a connection that allows data to be sent between the computing device  200  and the portable device  250 . The automatic creation of the connection can be by a service discovery protocol. The connection can allow the computing device  250  to request from the portable device values  275 . The values  275  may be for example the name, description or an icon of an application on the portable device. 
         [0024]    The values may be stored in the memory  245  of the computing device. The controller  265  can access the values  275  from the memory and display the values on the graphical user interface (GUI)  235 . The GUI may present in a menu that the values from the portable device  250 . The values may be links that if activated cause the application  210  to be retrieved from the portable device  250  and executed on the hardware virtualizer  215  of the computing device  200 . 
         [0025]    In one embodiment a menu presented by the graphical user interface may include a value for the application  210  and a link or value for a second application that is a native application  211  to the computing device. The menu may be presented as a folder that includes many values. 
         [0026]      FIG. 3  is a flow diagram of a method according to an example embodiment of the invention. The method can be for automatically presenting an application. The method can begin at  305  by receiving an advertisement from a portable device. Advertising can be by a service discovery protocol. A portable device that is connected by a wire or paired with the computing device can discover at  310  the portable device from the advertisement. 
         [0027]    The computing device can establish a connection with the portable device at  315 . The connection can be established automatically and allow the transfer of data between the computing device and the portable device. 
         [0028]    The computing device can determine an application that is available on the portable device at  320 . The determination may be from a request sent to the portable device from the computing device and the computing device may then receive from the portable device a list or values of an application that is available on the portable device. The value may be for example a name, description or an icon that is associated with the application on the portable device. 
         [0029]    The computing device may present the application on the portable device in a list at  325 . The list may include a native computing device application. The presentation can be done in a graphical user interface (GUI) such as a menu, folder, window or another GUI. 
         [0030]      FIG. 4  is a flow diagram of a method according to an example embodiment of the invention. The method can be for automatically presenting an application. The method can begin at  302  by pairing a portable device and computing device. If a portable device is paired with a computing device they can connect to each other automatically when they are on the same network or in range. For example if the portable device and the computing device are paired by Bluetooth they will automatically connect when they are in range of each other or if they are paired by WLAN then they may connect via an adhoc network if they are in range of each other or through an access point if they are both in range of an access point on the network. If the portable device and the computing device are paired then the portable device can advertise to the computing device. Advertising can be by a service discovery protocol. A portable device that is connected by a wire or paired with the computing device can discover at  310  the portable device from the advertisement. 
         [0031]    The computing device can establish a connection with the portable device at  315 . The connection can be established automatically and allow the transfer of data between the computing device and the portable device. 
         [0032]    The computing device can determine an application that is available on the portable device at  320 . The determination may be from a request sent to the portable device from the computing device and the computing device may then receive from the portable device a list or values of an application that is available on the portable device. The value may be for example a name, description or an icon that is associated with the application on the portable device. 
         [0033]    The computing device may present the application on the portable device in a list at  325 . The list may include a native computing device application. The presentation can be done in a graphical user interface (GUI) such as a menu, folder, window or another GUI. The computing device can execute the application in a hardware virtualizer on the computing device. 
         [0034]    Any of Pairing at  302 , advertising at  305 , discovering at  310 , establishing  315 , determining at  320 , present at  325  or executing at  330  can be performed automatically, for example without user input, if the computer device discovers the portable device. In one embodiment the connection between the portable device and the computing device is a secure connection. The secure connection prevents tampering with the applications and prevents access to information on the portable device from devices except the computing device. In one embodiment the portable device authenticates a user profile and the computing device authenticates a user profile to make the connection. The authentication of the user profile may be used to create the secure connection. 
         [0035]      FIG. 5  is a block diagram of a device according to an example embodiment of the invention. The device  500  can include a processor  505 , a controller hub  510  connected to the processor. The controller hub  510  may be in the same package as the processor  505 , may be on the same substrate as the processor  505  or in a separate package from the Processor  505 . The controller hub  510  can connect to a graphic controller  520 . 
         [0036]    A display  530  can be connected to the graphics controller  520 . The display  430  can display a graphical user interface. The graphic controller  520  can generate the signals that are received by the display and generate the graphics on the display. The controller hub  510  may connect to input devices. For example a keyboard  535  or a mouse  540  can be connected to the controller hub  510 . 
         [0037]    The controller hub may be connected to a computer readable media  515  or  516 . The computer readable media  515  or  516  can include code that if executed may cause the processor  505  of a computing device  500  to discover a portable device paired with the computing device. The code may cause computing device  500  to automatically authenticate the portable device. The code may cause computing device  500  to establish a secure connection to the portable device. The code may cause computing device  500  to determine an application available on the portable device. The code may cause computing device  500  to execute the application in a hardware virtualizer on the computing device. 
         [0038]    The code may generate a list that is presented on the display  530  by the graphics controller  520  or may authenticate the portable device using a user profile on the computing device and the portable device. 
         [0039]    The techniques described above may be embodied in a computer-readable medium for configuring a computing device to execute the method. The computer readable media may include, for example and without limitation, any number of the following: magnetic storage media including disk and tape storage media; optical storage media such as compact disk media (e.g., CD-ROM, CD-R, etc.) and digital video disk storage media; holographic memory; nonvolatile memory storage media including semiconductor-based memory units such as FLASH memory, EEPROM, EPROM, ROM; ferromagnetic digital memories; volatile storage media including registers, buffers or caches, main memory, RAM, etc.; and the Internet, just to name a few.
