Abstract: A method and apparatus is provided for securely obtaining input from a touchscreen. A secure execution environment may be implemented (e.g., at a processor), where the secure execution environment may include a touchscreen driver. A keypad image may be sent from the secure execution environment to be displayed by a touchscreen. An input location may be received at the secure execution environment from the touchscreen driver. Such input location may be converted at the secure execution environment into a character, symbol, or a request to change the keypad image displayed at the touchscreen. In one implementation, the secure execution environment may further implement a display driver which sends the keypad image to the touchscreen. The secure execution environment may implement driver keypad image mapping function that maps the keypad image to a character set.

Abstract: Systems and methods are disclosed for coordinating resource usage between applications in a tightly sandbox environment. A scheduling indicator can be left in a system file that multiple applications can use to align their requests for a system resource. Alternatively, IP loopback can be used to pass a scheduling indicator between applications that are otherwise sandboxed. If either of these approaches is not possible, then applications can schedule system resource requests using a common algorithm that selects a start time and optionally a period of subsequent system resource requests based on a common piece of information such as a system clock signal or IP address. In these ways the total amount of time during which the system resource is being utilized by various applications can be reduced, thus reducing power consumption, and network activity.

Abstract: Systems and methods for wireless communications are provided. These include data deciphering components, interrupt processing components, adaptive aggregations methods, optimized data path processing, buffer pool processing, application processing where data is formatted in a suitable format for a destination process, and Keystream bank processing among other hardware acceleration features. Such systems and methods are provided to simplify logic designs and mitigate processing steps during wireless network data processing.

Abstract: Aspects describe selection of a mobility protocol after a mobile device has been authenticated with a network. Selection of mobility protocol after authentication can mitigate the amount of time needed to implement the mobility protocol. The mobility protocols include a simple IP protocol, a proxy mobile IP protocol, and a client mobile IP protocol. Implementation of simple IP protocol and proxy mobile IP protocol are performed in a similar manner from the perspective of a mobile device. If IPCP negotiation is successful, proxy mobile IP protocol or simple IP protocol can be selected. If IPCP negotiation is not successful, client mobile IP protocol can be selected.

Abstract: This disclosure describes systems, methods, and apparatus for determining proximity between networked devices without requiring those devices to share location information either because of privacy or because such information cannot be obtained. To do this, access points for a plurality of networked devices are compared, and those devices detecting, or detected by, the same access points are deemed proximal to each other. Software, or features of software, can be initiated on those networked devices that are proximal to other networked devices and the proximal networked devices can be given information enabling them to identify and communicate with each other.
