Abstract: If a secure element accesses a resource that is separate from the secure element, conducting a secure transaction can be inefficient in terms of power or time. Power usage is inefficient if the resource is never permitted to sleep, and transaction time is inefficient if the resource is permitted to sleep, and the user experiences a delay. To enable dual efficiency, a resource entity is permitted to be powered down. The resource entity is then powered up speculatively by an activation controller. The activation controller predicts an upcoming secure transaction based on sensor output, such as a position fix or a detected electromagnetic field. Based on monitored sensor output, the activation controller issues an activation signal to power up the secure element or the resource entity prior to initiation of the upcoming secure transaction. Thus, power can be conserved without introducing a transaction-processing latency.

Abstract: This document describes a secure element that leverages the resources of a computer system to perform specialized functions using sensitive information. The secure element securely stores sensitive information on flash memory of the computer system. In response to a request requiring use of sensitive information, the secure element loads a security application and sensitive information from the computer system. By leveraging external resources, the secure element may flexibly accommodate increasing resource requirements of the computer system and be used in a wide range of computer systems.

Abstract: This document describes methods and systems of on-device real-time translation for media content on a mobile electronic device. The translation is managed and executed by an operating system of the electronic device rather than within a particular application executing on the electronic device. The operating system can translate media content, including visual content displayed on a display device of the electronic device or audio content output by the electronic device. Because the translation is at the OS level, the translation can be implemented, automatically or based on a user input, across a variety of (including all) applications and a variety of content on the electronic device to provide a consistent translation experience, which is provided via a system UI overlay that displays translated text as captions to video content or as a replacement to on-screen text.
