  • Publication number: 20160183191
    Abstract: The techniques and systems described herein implement direct memory access in association with a wireless data transfer. In one example, data units are received at a device and it is determined that the data units have been transferred using low-power consumption data transfer and that the data units are to be directly stored in a predetermined memory (e.g., a dedicated memory) of the device. In another example, a first device provides an instruction to a partner device to store data in specific storage location(s) so that the data can be retrieved from the specific storage location(s) without interrupting a main processor of the partner device. The data may also be directly stored in the predetermined memory of the first device without interrupting a main processor of the first device.

  • Patent number: 9245254
    Abstract: Techniques for ability enhancement are described. Some embodiments provide an ability enhancement facilitator system (“AEFS”) configured to enhance voice conferencing among multiple speakers. Some embodiments of the AEFS enhance voice conferencing by recording, translating and presenting voice conference history information based on speaker-related information, wherein the translation is based on language identification using multiple speech recognizers and GPS information. The AEFS receives data that represents utterances of multiple speakers who are engaging in a voice conference with one another. The AEFS then determines speaker-related information, such as by identifying a current speaker, locating an information item (e.g., an email message, document) associated with the speaker, or the like. The AEFS records conference history information (e.g., a transcript) based on the determined speaker-related information.

  • Publication number: 20160021614
    Abstract: The techniques described herein reduce a rate at which a mobile device consumes energy when receiving, processing and storing data events (e.g., emails, instant messages, social networking messages and notifications, etc.). In various embodiments, the techniques may be implemented in accordance with a connected standby mode of operation for the mobile device. Therefore, the techniques may decouple data reception from data processing when exchanging data events in the connected standby mode. In various embodiments, the techniques may store persistent memory operations for multiple data events in a temporary cache and process the stored persistent memory operations as a batch (e.g., perform the persistent memory operations together). In various embodiments, the techniques may partition data storage space allocated for data communications applications on the mobile device.
