     DETAILED DESCRIPTION 
     It will be readily understood that the components of the embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations in addition to the described example embodiments. Thus, the following more detailed description of the example embodiments, as represented in the figures, is not intended to limit the scope of the embodiments, as claimed, but is merely representative of example embodiments. 
     Reference throughout this specification to “one embodiment” or “an embodiment” (or the like) means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” or the like in various places throughout this specification are not necessarily all referring to the same embodiment. 
     Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that the various embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obfuscation. The following description is intended only by way of example, and simply illustrates certain example embodiments. 
     Disintegrated computing involves a technological environment wherein users carry a minimum mobile information handling device load (pertaining to both the size and the number of devices) capable of interacting with other computing devices, peripherals, and electronic products. This interaction operates to extend mobile information handling device capabilities and to create a more complete computing experience wherein a user may communicate with a wide range of electronic products through a single mobile device. For example, a user may carry a smartphone that is capable of interacting with a high definition television (HDTV) at home and a laptop and digital projector located at his place of employment. The external devices accessible through a mobile information handling device may be public or private, and may additionally be owned by others. 
     A mobile information handling device may connect with an external device using a wide range of existing communication protocols. For example, wireless protocols such as Bluetooth® and Wi-Fi or physical connections such as USB, FireWire®, Thunderbolt®, HDMI, DisplayPort, and Ethernet. BlueTooth is a registered trademark of Bluetooth SIG, Inc. FireWire is a registered trademark of Apple Inc. According to existing technology, mobile devices primarily connect with external devices in close proximity, such as those located within a personal area network (PAN), physically connected through an Ethernet or FireWire® cable. In these situations, a realistic maximum distance between devices ranges from a few feet for wired connections to thirty feet for wireless connections (e.g., the range of Bluetooth® wireless technology). In addition, certain wireless connections, such as PAN connections, can only be established between devices in the same room, as these connections cannot be maintained through barriers such as walls. As such, when a mobile device is moved a certain distance away from a connected device or into another room, the connection is terminated without any user interaction. The connection termination occurs simply because the connection cannot be maintained unless the devices are within a certain local distance and/or line of sight of each other. 
     An increasing number of devices are able to establish connections over greater distances. For example, a mobile device may connect with a HDTV or a printer across an IP network, such as a WAN, LAN, or WLAN, wherein the devices do not need to be physically close to each other. These long-range connections provide for more flexibility and allow a mobile device to maintain a connection when a user is no longer in close proximity to the connected external device. 
     However, the long-range connectivity may produce certain unintended consequences wherein a user may no longer want to be connected to one or more devices after a period of interaction is complete. For example, a user may connect a tablet computing device to a HDTV through a WLAN in order to display certain images on the HDTV during a presentation at a certain location, such as a conference room in a corporate office building. After the presentation, the user leaves the conference room and opens a personal, confidential document on the tablet computing device in a second location located several floors above the conference room. However, the tablet computing device and the HDTV may maintain their connection over a large distance because they are connected through an IP network. As such, because the user did not disconnect the tablet computing device from the HDTV, the personal, confidential document may also be displayed on the HDTV in the conference room. 
     This situation described immediately above may also occur with many other devices, such as a network printer, digital projector, or another computing device. For example, a user may connect a mobile device to a first printer located in a common office area through a WLAN to print a certain document. Later, the user may attempt to print a personal email from the mobile device at a second printer located in his office and also available through the WLAN. However, if the user did not directly disconnect from the first printer, the personal email may print at the first printer located in the common office area. 
     Until recently, when a user was no longer in close proximity with a connected device, it was likely that the devices no longer connected. For example, if a mobile device was connected to a digital projector in a conference room through Bluetooth®, FireWire®, HDMI, or DisplayPort, then the user could assume that the mobile device was no longer connected when removed from the conference room or the physical connection was removed. However, advances in network technology, information handling devices, and other electronic products make it possible to initiate and maintain connections over very large distances. Certain devices have attempted to solely utilize one or more timeout mechanisms to terminate a connection, for example, responsive to expiration of a predetermined time period or after a certain period of inactivity. Nonetheless, such time-based connection termination functions have proved ineffective in real-world situations, as they result in unintended connection terminations and require users to reconfigure settings for each situation and connected device. 
     Embodiments provide one or more policies for managing connection termination between an information handling device and another system based on one or more physical characteristics of the information handling device. According to embodiments, relevant physical characteristics of an information handling device may comprise a location, motion, direction of motion, or some combination thereof. 
     An information handling device configured according to embodiments may be comprised of or be in communication with elements configured to measure certain physical characteristics of the device. The information handling device compares the physical characteristics to one or more disconnection policies and activates a disconnection event if the physical characteristic matches a setting in the one or more disconnection policy. A disconnection policy may be configured according to embodiments to be comprised of one or more policy settings, which provide specific disconnection policies, such as policies pertaining to time, distance, devices, connections, and disconnection events. A non-limiting example provides that a smartphone may have an element for determining geographic location and may terminate a connection with a device responsive to moving a certain distance away from a connected system. For example, a module or application may operate on an information handling device that receives physical characteristic measurements as input and continuously or at predetermined intervals accesses device disconnection policies to determine whether one or more policies have been triggered. 
     Referring to  FIG. 1 , therein is provided an example process for location-based connection termination according to an embodiment. An information handling device connects with an external system through a network  101  (e.g., WAN, WLAN). According to embodiments, an information handling device may be comprised of any information handling device capable of carrying out embodiments provided herein, including, but not limited to, a smartphone, tablet or slate computing device, personal digital assistant (PDA), e-reader, and laptop computer. In addition, embodiments may be configured to operate with any external system capable of establishing a connection with information handling devices arranged according to embodiments. Non-limiting examples of external systems include information handling devices, networks, and external systems such as televisions (e.g., HDTVs), printers, digital projectors, and integrated car entertainment (ICE) devices. 
     A location measuring element on the information handling device measures the current location of the information handling device  102 . According to embodiments, the location measuring element may be any element capable of determining the location of the information handling device in a manner suitable for carrying out embodiments described herein. A non-limiting example provides that the location information may be geographic location data or a location within a specific system, for example, a network of devices configured within a structure (e.g., office building or manufacturing facility). Illustrative and non-restrictive examples of location measuring elements include a global positioning system (GPS) receiver, electronic compass, and electronic tags, such as the RFID tags used in combination with the network of location aware wall-plates in U.S. Pat. No. 7,257,108, entitled “Determining the Physical Location of Resources on and Proximate to a Network,” the contents of which are incorporated by reference as if fully set forth herein. According to embodiments, device physical characteristics may be measured based on certain settings, including continuously, responsive to detected changes (e.g., device connects to external system, detected movement, etc.), or at predetermined time intervals. 
     If a change in location is measured by the location measurement element  103 , the information handling device accesses the disconnection policy  104 . According to embodiments, the disconnection policy may be configured to provide one or more policies for terminating a connection based on the location of the information handling device. Non-restrictive examples provide that a policy may be based on the distance traveled by the information handling device or the geographic location of the information handling device. For example, a policy may be configured to terminate a connection if the information handling device travels a certain distance away from the connected system (e.g., thirty feet, one hundred yards, one mile, etc.). In another example, a connection may be terminated if the information handling device moves to one or more specified geographic locations, such as outside of a certain area (e.g., outside of an office building). In addition, the information handling device may have different policies, including, but not limited to, policies based on particular devices, locations, time of day, connection type, active applications, and device activity. 
     If the location information matches connection termination criteria specified in the disconnection policy  105 , then a disconnection event may be triggered on the information handling device  106 . According to embodiments, a disconnection event may be configured in the disconnection policy and may include providing a warning to the user, for example, that the device is near a disconnection threshold, prompting the user as to whether they would like to continue or disconnect, terminating the connection, maintaining the connection, or combinations thereof. 
       FIG. 2  provides an example process for movement-based termination according to an embodiment. An information handling device connects with an external system through a network  201  (e.g., an IP network). A movement measuring element on the information handling device measures the movement status of the information handling device  202 . According to embodiments, the movement status of the information handling device may comprise one or more physical characteristics of the information handling device indicating the level of movement of the device. Illustrative and non-restrictive examples include acceleration as measured by an integral accelerometer sensor, an amount of movement within a certain period of time (e.g., movement within an x, y, z plane; constant movement for longer than thirty seconds, indicating, for example, that a user is walking with the device), direction determined using a compass sensor, or combinations thereof. 
     If a change in movement is measured by the movement measurement element  203  (e.g., the amount of motion increases or the device acceleration increases), the information handling device accesses the disconnection policy  204 . If the movement information matches termination connection criteria specified in the disconnection policy  205  (e.g., device movement exceeds a threshold), then a disconnection event may be triggered on the information handling device  206 . 
     Referring to  FIG. 3 , therein is provided an example disconnection policy configured according to an embodiment. In the example of  FIG. 3 , the information handling device  301  is a tablet computing device having a disconnection policy  302  configured for different external systems and physical characteristics. As shown in FIG.  3 , a policy setting is configured for a network printer  303 , wherein a user prompt disconnection event is triggered if acceleration is greater than fifteen m/s 2 , movement is detected for longer than forty-five seconds, or the device is moved greater than thirty feet from the network printer. Another policy setting is provided for a HDTV  304  that provides for connection termination if acceleration is greater than thirteen m/s 2 , movement is detected for longer than thirty seconds, or the device is moved outside of the conference room where the HDTV is located.  FIG. 3  additionally provides for a default policy setting  305  for non-specified devices. The default policy setting  306  provides for a user prompt if acceleration is greater than twenty m/s 2 , movement is detected for longer than one minute, or the device is moved greater than fifty feet. Although certain disconnection policy values relating to acceleration, constant motion, and distance are described in  FIG. 3 , embodiments are not limited to these policy settings, disconnection events, values or ranges of values, or combinations thereof, as these are only meant to serve as part of an example. 
     While various other circuits, circuitry or components may be utilized,  FIG. 4  depicts a block diagram of one example of information handling device circuits, circuitry or components. The example depicted in  FIG. 4  may correspond to computing systems such as the THINKPAD series of personal computers sold by Lenovo (US) Inc. of Morrisville, N.C., or other devices. As is apparent from the description herein, embodiments may include other features or only some of the features of the example illustrated in  FIG. 4 . 
     The example of  FIG. 4  includes a so-called chipset  410  (a group of integrated circuits, or chips, that work together, chipsets) with an architecture that may vary depending on manufacturer (for example, INTEL, AMD, ARM, etc.). The architecture of the chipset  410  includes a core and memory control group  420  and an I/O controller hub  450  that exchanges information (for example, data, signals, commands, et cetera) via a direct management interface (DMI)  442  or a link controller  444 . In  FIG. 4 , the DMI  442  is a chip-to-chip interface (sometimes referred to as being a link between a “northbridge” and a “southbridge”). The core and memory control group  420  include one or more processors  422  (for example, single or multi-core) and a memory controller hub  426  that exchange information via a front side bus (FSB)  424 ; noting that components of the group  420  may be integrated in a chip that supplants the conventional “northbridge” style architecture. 
     In  FIG. 4 , the memory controller hub  426  interfaces with memory  440  (for example, to provide support for a type of RAM that may be referred to as “system memory” or “memory”). The memory controller hub  426  further includes a LVDS interface  432  for a display device  492  (for example, a CRT, a flat panel, a projector, et cetera). A block  438  includes some technologies that may be supported via the LVDS interface  432  (for example, serial digital video, HDMI/DVI, display port). The memory controller hub  426  also includes a PCI-express interface (PCI-E)  434  that may support discrete graphics  436 . 
     In  FIG. 4 , the I/O hub controller  450  includes a SATA interface  451  (for example, for HDDs, SDDs, 480 et cetera), a PCI-E interface  452  (for example, for wireless connections  482 ), a USB interface  453  (for example, for input devices  484  such as a digitizer, keyboard, mice, cameras, phones, storage, other connected devices, et cetera.), a network interface  454  (for example, LAN), a GPIO interface  455 , a LPC interface  470  (for ASICs  471 , a TPM  472 , a super I/O  473 , a firmware hub  474 , BIOS support  475  as well as various types of memory  476  such as ROM  477 , Flash  478 , and NVRAM  479 ), a power management interface  461 , a clock generator interface  462 , an audio interface  463  (for example, for speakers  494 ), a TCO interface  464 , a system management bus interface  465 , and SPI Flash  466 , which can include BIOS  468  and boot code  490 . The I/O hub controller  450  may include gigabit Ethernet support. 
     The system, upon power on, may be configured to execute boot code  490  for the BIOS  468 , as stored within the SPI Flash  466 , and thereafter processes data under the control of one or more operating systems and application software (for example, stored in system memory  440 ). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS  468 . As described herein, a device may include fewer or more features than shown in the system of  FIG. 4 . 
     For example, referring to  FIG. 5 , with regard to smartphone and/or tablet circuitry  500 , an example includes INTEL, AMD, and ARM based systems (systems on a chip [SoC]) design, with software and processor(s) combined in a single chip  510 . Internal busses and the like depend on different vendors, but essentially all the peripheral devices ( 520 ) may attach to a single chip  510 . In contrast to the circuitry illustrated in  FIG. 5 , the tablet circuitry  500  combines the processor, memory control, and I/O controller hub all into a single chip  510 . Also, INTEL, AMD, and ARM SoC based systems  500  do not typically use SATA or PCI or LPC. Common interfaces for example include SDIO and I2C. There are power management chip(s)  530 , which manage power as supplied for example via a rechargeable battery  540 , which may be recharged by a connection to a power source (not shown), and in the at least one design, a single chip, such as  510 , is used to supply BIOS like functionality and DRAM memory. 
     INTEL, AMD, and ARM SoC based systems  500  typically include one or more of a WWAN transceiver  550  and a WLAN transceiver  560  for connecting to various networks, such as telecommunications networks and wireless base stations. Commonly, an INTEL, AMD, and ARM SoC based system  500  will include a touchscreen  570  for data input and display. INTEL, AMD, and ARM SoC based systems  500  also typically include various memory devices, for example flash memory  580  and SDRAM  590 . 
     Embodiments may be implemented in one or more information handling devices configured appropriately to execute program instructions consistent with the functionality of the embodiments as described herein. In this regard,  FIGS. 4-5  illustrate non-limiting examples of such devices and components thereof. While mobile information handling devices such as tablet computers, laptop computers, and smartphones have been specifically mentioned as examples herein, embodiments may be implemented using other systems or devices as appropriate. 
     As will be appreciated by one skilled in the art, various aspects may be embodied as a system, method or computer (device) program product.
