A system and method for a back stack in a multi-application environment, wherein the method comprises adding an entry to a last-in-first-out (LIFO) data structure, the entry comprising application state information descriptive of an application state of a software application and display state information descriptive of a display state of a display surface of a touch screen device, adjusting a LIFO data structure pointer to reflect a revised LIFO data structure state resulting from the adding the entry, receiving a back button actuation indication, in response to receiving the back button actuation indication, restoring the software application to the application state and restoring the display surface to the display state, and readjusting the LIFO data structure pointer to reflect an original LIFO data structure state that existing prior to the adding the entry.

An information handling system includes a primary integrated display device housing and a second integrated display device housing attached via a hinge and a processor to determine a first relative orientation of the primary integrated display device housing to the second integrated display device housing from a plurality of orientation sensors. The processor further determines a working software application context by detecting at least a first software application running on the information handling system wherein the working software application context further includes an operating state rank of the first software application relative to other software applications. The processor detects a required user input to the first software application and alters a location of a first software application display window and a virtual input softkey on a display device based on the first relative orientation and displaces second software application window of a second software application with a previously-higher the operating state rank.

System and method for positioning an application window based on usage context for dual screen display device

An information handling system includes a primary integrated display platform and a secondary integrated display platform attached via a hinge, and including a passive cooling system, a dynamic thermal management system, and a processor. The information handling system further includes an application window locator system for determining a location of a software application display window running on the information handling system on the primary integrated display platform or the secondary integrated display platform.

An information handling system includes a primary integrated display device and a second integrated display device attached via a hinge and a processor. The processor determines a first relative orientation of the primary integrated display device to the second integrated display device from orientation sensors. The processor further determines a working software application context by detecting at least a first software application running on the information handling system wherein the working software application context further includes an operating state rank of the first software application relative to other software applications.

A method and apparatus for automatically securing non-volatile (NV) storage in an integrated circuit provides improved resistance to code copying and reverse-engineering attacks. External interfaces that provide read access to the NV storage are be disabled, for a predetermined time after a reset or other initialization signal is received. An internal lock state bit or key is checked as well as an external lock prevent indication. If the lock prevent indication is not received, or the internal lock state bit is already set, then the integrated circuit is operated under a locked condition, in which external access to the NV storage values is prevented. The lock prevent indication may be a signal provided during reset of the integrated circuit on a terminal that is used for another purpose after initialization of the integrated circuit.

Method and apparatus for playing analog audio in an electronic audio system having multiple audio codecs, only one of which has a direct hardware connection to the analog audio source. First analog audio data is received from the analog audio source at a first audio codec, and converted to digital audio data using the first audio codec. The digital audio data is stored in a memory, and read back from the memory, transferred to a second audio codec. The digital audio data is then converted to second analog audio data using the second audio codec, and output from the second audio codec. An audio controller may be used to store the digital audio data in a loopback buffer within the memory, read the digital audio data from the loopback buffer, and may further be programmed to operate in a prepare loopback state, a loopback running state, and a recording state.
