20120105147 | MATCHING NETWORK FOR TRANSMISSION CIRCUITRY - The present disclosure relates to transmission circuitry of a wireless communication device. The transmission circuitry includes power amplifier circuitry, an output matching network, and impedance control circuitry. The power amplifier circuitry amplifies a radio frequency (RF) input signal to provide an amplified RF output signal, which is passed through the output matching network and transmitted via one or more antennas. As the center frequency of the RF input signal and conditions of operating parameters change, the impedance control circuitry adjusts the values of one or more variable impedance elements of the output matching network in a desired fashion. The values of the variable impedance elements are adjusted such that the output matching network concurrently and dynamically presents the desired load impedances at the center frequency and at one or more harmonics of the RF input signal to achieve a given performance specification. | 05-03-2012 |

The graphical user interface engine is further configured to, for each event notification, adjust the appearance of the corresponding passive tracking indicator in response to the determined intensity value, such that the appearance of the passive tracking indicator changes over time according to the determined intensity values. | 11-18-2010 |
20130051755 | METHOD FOR TRANSFERRING MEDIA PLAYBACK FROM A DIFFERENT DEVICE - Transfer of media playback from a first device to a second device is based on a media entry point identifier. For example, a movie playing on a source device such as a movie theater screen may be quickly and easily transferred to a user's handheld device for playback on the handheld device or vice versa. Playback of the transferred media begins at or near a point within the transferred media at which the user requested media playback transfer. In one embodiment, media playback transfer relies on information captured from the source device, such as a video frame, a media progress bar, or a visual code. In another embodiment, the user device is associated with a user account that is different from the user account associated with the source device or the source device simply is not associated with a user account. In another embodiment, transfer of the media playback involves applying to the user device the settings of the source device. | 02-28-2013 |
20130114849 | SERVER-ASSISTED OBJECT RECOGNITION AND TRACKING FOR MOBILE DEVICES - Exemplary embodiments for performing server-assisted object recognition and tracking are disclosed herein. For example, in certain embodiments of the disclosed technology, one or more objects are efficiently recognized and tracked on a mobile device by using a remote server that can provide high capacity computing and storage resources. With the benefit of high-speed image processing on a remote server and high-bandwidth communication networks connecting the mobile device and the remote server, it is possible to identify an object and to track changes in the object's characteristics or location, so that a user experiences seamless, real-time tracking. | 05-09-2013 |
20130117464 | PERSONALIZED MEDIA FILTERING BASED ON CONTENT - Personalized media filtering for a mobile electronic device can be implemented. By supporting receipt of personal media filter criteria, flexible personalization options can be implemented. Personalized media filtering can allow for interactively receiving personal media filter criteria and applying the filter criteria to the media content during the media presentation. One possible blocking response is to block portions of the content. Other possible responses include switching between broadcast stations or playlists. A prevalence metric can indicate how often a particular content item, such as a word, has been filtered from the media content. When the prevalence metric exceeds a threshold, the technology can automatically respond in a variety of ways, such as by blocking a source of the presented media content from future presentation. Interactively establishing personalized filter criteria can be implemented during ongoing presentation, for immediate use in filtering during the presentation. | 05-09-2013 |
