  • Publication number: 20160337419
    Abstract: The present disclosure relates to a method and a media device for pre-buffering media content streamed to the media device from a server system. The media device is connected to a network and has a rechargeable battery. The media device determines, by means of a bandwidth logic, an available network bandwidth and, by means of a charging logic, a charging level of the rechargeable battery. Based on these determinations, i.e. based on the determined available network bandwidth and the determined charging level of the rechargeable battery the media device selects a pre-buffering policy, by means of a pre-buffering logic, and pre-buffers media content, by means of the pre-buffering logic, from the server system in accordance with the selected pre-buffering policy.

  • Publication number: 20160335049
    Abstract: This disclosure concerns the providing of media, and more particularly to the streaming of media. In accordance with an example embodiment, while receiving a first media content item of the streamed media content, a request for a second media content item is received, and a first data message sent to the computer server system, to return the second media content item. In response to receiving a second data message the electronic device begins to perform playback of the second media content item combined with the playback of the first media content item at the user interface of the electronic device, e.g. by pausing the first media content item. The electronic device receives a request for including the second media content item in a playlist associated with a current portion of the day, and includes the second media content item into the playlist associated with the current portion of the day.

  • Patent number: 8049567
    Abstract: A circuit comprising a DC current source and at least two spin torque oscillators, the at least two spin torque oscillators being electrically coupled to each other and to the DC current source. A circuit comprising phase shifting means is connected in such a way as to cause a phase shift between current and voltage through the spin torque oscillators. An advantage is that the controlled phase shift significantly increases the tolerance for deviating anisotropy fields, which makes manufacturing of spin torque oscillator devices much more feasible in practice.

  • Patent number: 7269510
    Abstract: Device (1) and carrier for providing map information data (3) interactively to a display unit (5). The device (1) comprises a processor (7) and a memory (9) comprising a map information database (11) comprising map information data (3) representing geographical features, the map information data (3) being based on aggregations of at least one of nodes (15), links (17) and rings (19), each one of which corresponding to geographic features. The map information data (3) of a higher resolution level comprises additional map information data, resulting in more detailed map information (3) presented on the display unit (5), compared to the map information data (3) of a lower resolution level. The map information data (3) of a higher resolution level is generated by enhancement of the map information data (3) of a lower resolution level combined with the additional data, the enhancement being based on disaggregation of nodes (15), links (17) and rings (19).

  • Patent number: 7020107
    Abstract: An embodiment of the invention provides a method for effecting switchback on a spatial division multiple access (SDMA) PHS channel. A communication signal is broadcast over each of one or more SDMA channels of a multi-access channel to one or more corresponding user terminals. A set of transmit spatial weights is determined for a synchronization burst to a user terminal attempting to reestablish communication over an SDMA channel of the multi-access channel. The set of transmit spatial weights is determined such that interference caused by one or more communication signals to the synchronization burst is reduced.
