Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for voice-based device operation mode management. Example methods may include determining that a device is coupled to an accessory device, and determining that being coupled to the accessory device triggers activation of a first operation mode at the device. The first operation mode presents digital content at the display in a user interface having a first content density that is less than a second content density of a second operation mode. Example methods may include causing the device to activate the first operation mode, receiving first voice data indicative of a request to change the device operation mode to the second operation mode, and causing the device to activate the second operation mode.

Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for selective requests for authentication for voice-based launching of applications. Example methods may include receiving first audio data representing an utterance, determining that the device is in a first operating mode when the audio data was received, determining that the device is in a locked state when the audio data is received, and receiving, from a remote system, a command to display information based at least on part on the audio data. Certain methods may include receiving an indication that the utterance was spoken by a user authorized to access the information while in the first operating mode and the locked state, and causing presentation of the information by the device.

Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for voice-forward graphical user interface mode management. Example methods include determining that a device is coupled to an accessory device, determining that being coupled to the accessory device causes the device to deactivate a first operating mode and activate a second operating mode, where the second operating mode has a lower content density than the first operating mode, and determining that an application setting of an application executing on the device is causing the device to remain in the first operating mode. Example methods may include determining that a new value is associated with the application setting, and causing the device to activate the second operating mode.

Abstract: In one illustrative example, a method in a communication device adapted for communications using Hypertext Transport Protocol (HTTP) involves setting, at the communication device, an HTTP cookie which includes a user identification of a user of the communication device and a message portion which is signed with a digital signature of the user. The communication device sends, to an application server site via the communication network, a request message which includes the HTTP cookie. If verification of the digital signature at the application server site is successful, the communication device will receive access to an application service of the application server site. In one variation, the HTTP cookie is alternatively set with a group identification of a group with which the user is associated, and the message portion is signed with a digital signature of the group.

Abstract: One embodiment of the present invention provides a system that executes an application designed for one application framework in a different application framework. First, the system receives an application designed to operate in the first application framework. The system determines a first set of security permissions used by the application in the first application framework, and maps these security permissions into a second set of security permissions associated with the second application framework. The system then configures the second application framework to provide the second set of security permissions. These steps allow the application to execute transparently in the second application framework with substantially similar security behavior as in the first application framework.

Abstract: Example methods and apparatus to display mobile device contexts are disclosed. An example method includes displaying a first context in a user interface of a mobile device based on first device platform information, the first context including a first arrangement of information, graphics, and application icons that are associated with the first device platform information, determining that second device platform information received after the first device platform information corresponds to a second context, the second context being different from the first context and including a second arrangement of information, graphics, and applications that are associated with the second device platform information, and displaying the second context in the user interface replacing the first context without prompting a user of the mobile device.

Abstract: In general, the invention relates to a method. The method includes receiving notification, which includes context information, of a trap. The method further includes accessing, based at least partially upon the context information, a particular instruction that caused the trap, determining, based at least partially upon the context information, a particular address that is to be accessed by the particular instruction, updating a set of log information to indicate accessing of the particular address, causing subsequent accesses of the particular address to not give rise to a trap, after causing subsequent accesses of the particular address to not give rise to a trap, accessing the particular address, after accessing the particular address, causing subsequent accesses of the particular address to give rise to a trap, and causing the particular instruction to not be executed.

The first AEE is configured to be isolated from the second AEE. The first software application associated with the first AEE is configured to be processed on the first AEE such that the first software application is denied direct access to the second AEE. A second software application associated with the second AEE is configured to be processed on the second AEE such that the second software application is denied direct access to the first AEE.

Abstract: An improved web application framework methodology enables the creation of web applications which can respond to client requests in a fashion that results in rendering which appears on the client to be independent of scripting capability.

Abstract: A mechanism is disclosed for enabling multiple processes to share the same portion of physical memory. The first time an instance of a process is executed, a list of common components is compiled. The compiled code is then written into a newly created mappable data structure, which is stored into persistent storage. The next time an instance of that process is executed, the mappable data structure is mapped into a portion of the process instance's virtual memory space. This enables the process instance to invoke the compiled code for the common components. Multiple instances of the process may have their virtual memory spaces mapped to the same mappable data structure in this way. Thereafter, it is up to the operating system to load the contents of the mappable data structure into a portion of physical memory, and to ensure that all of the process instances share that physical memory portion.

Abstract: Techniques are disclosed for sharing programmatic modules among isolated virtual machines. A master JVM process loads data from a programmatic module, storing certain elements of that data into its private memory region, and storing other elements of that data into a “read-only” area of a shareable memory region. The master JVM process copies loaded data from its private memory region into a “read/write” area of the shareable memory region. Instead of re-loading the data from the programmatic module, other JVM processes map to the read-only area and also copy the loaded data from the read/write area into their own private memory regions. The private memory areas of all of the JVM processes begin at the same virtual memory address, so references between read-only data and copied data are preserved correctly. As a result, multiple JVM processes start up faster, and memory is conserved by avoiding the redundant storage of shareable data.

Abstract: Techniques for processing native events associated with tasks that are concurrently supported in a virtual machine are disclosed. The techniques allow the user of a virtual machine to concurrently perform tasks even if these tasks require processing of platform-specific (or native) events (e.g., platform-specific input). A smart event-dispatcher is used to dispatch native events to multiple tasks that are concurrently supported by the virtual machine. The smart event-dispatcher can determine which one of a plurality of concurrent tasks should receive the native event for processing. The determination can be made based on a variety of different criteria. In mobile devices, the foreground task is typically the only task that is displayed for the user of mobile devices at any given time. Thus, dispatching events to the foreground task is especially useful for a virtual machine that support a mobile device.

Abstract: A mechanism is disclosed for enabling virtual method dispatch structures (vstructures) to be created on an as-needed basis. When an object class is loaded, a vstructure specific to that object class is not created. Rather, the vstructure for that object class is created only if and when a virtual method of that object class is invoked. By creating vstructures on an as-needed basis, the number of vstructures created during the execution of a program is minimized. This in turn reduces the number of vstructures that need to be updated whenever a reference to a method is changed (for example, as a result of a garbage collection operation). To further optimize the efficiency of the vstructure update process, vstructure entries that point to the same method may be linked. That way, when the reference to a method is changed, all vstructures affected by that change can be quickly identified.
