Abstract: Media sharing using contact data involves identifying contact records on a personal electronic device of a user. Each of the contact records includes a contact address of a person associated with the respective contact record. The contact records are communicated to a media sharing service via a network. Media items of the user are sent to the sharing service. One or more of the contact records are associated with each of the media items. A notification is sent to the persons associated with the one or more contact records. The notification describes sharing of the media items associated with the contact records. The sharing service facilitates access to the media items by the persons associated with the contact records in response to the persons receiving the notification.

Abstract: Methods and systems are disclosed to generate a data map for a data storage device. A data map may be generated by scanning, during a power-on initialization process, data units of data stored on a data storage medium of a data storage device. The scanning may start from a selected data unit and proceed through the data units in an order opposite to a write order to identify a first data unit that is not fully erased. Also. an error recovery status of the first data unit may be determined based on an error correction code. A likely erased status of the first data unit may be assigned when the determined error recovery status is unrecoverable.

Abstract: A method for encoding a video sequence comprising an independent sequence of image frames, wherein at least one reference image frame is predictable from at least one previous image frame that is earlier than the previous reference image frame in decoding order. An indication of at least one image frame is encoded into the video sequence, which indicated image frame is the first image frame, in decoding order, of the independent sequence, said at least one reference image frame being included in the sequence. In the decoding phase, the indication of at least one image frame is decoded from the video sequence, and the decoding of the video sequence is started from said first image frame of the independent sequence, whereby the video sequence is decoded without prediction from any image frame decoded prior to said first image frame.

Abstract: Systems and methods of managing features or functions of an implantable cardiac device involve forming a baseline evoked response template prior to delivery of defibrillation therapy to a patient's heart, and acquiring a post-shock evoked response signal subsequent to defibrillation therapy delivery.

Abstract: Methods and systems are directed to detecting atrial tachyarrhythmia. A plurality of A-A intervals is detected. The detected A-A intervals are selected and used to detect atrial tachyarrhythmia. Selecting A-A intervals may be based on determining that A-A intervals are qualified.

Qualified A-A intervals may also be determined based on events occurring between consecutively sensed atrial events of the particular A-A interval, and whether the duration of the particular A-A interval falls within the predetermined duration range, for example.
