Abstract: Techniques are disclosed for selecting frames for decode and display during different playback modes of a media player. Prediction dependencies may be estimated among frames from a sample table of a media item identifying dependency state among frames in the media item. Based on a playback rate of a media player, a collection of frames may be identified from the media item that have presentation times within a display refresh time of the player. A frame may be selected for decode and display during the display refresh time based on the estimated prediction dependencies. The selected frame may be decoded for display during the player display refresh time.

Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified.

Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

Abstract: Communicating wireless devices collaborate and utilize waveforms to enable secure channel estimation. To protect against a repetitive replay attack, some embodiments include Single Carrier Physical Layer (SC-PHY) waveforms and/or interpolated OFDM waveforms that do not include a repeatable or predictable structure. The waveforms are transmitted in ranging packet structures that are compatible with legacy 802.11 technologies that do not utilize secure channel estimation. The ranging packets are received in combination with the information previously exchanged to enable the receiving wireless system to securely determine a channel estimate (e.g., determine a channel estimate without an interloper transmission that is not an authentic first arrival path in a multi-path channel between the wireless systems). Thus, one or both of the wireless systems can estimate the distance between them (or range). Devices utilizing legacy 802.

Abstract: Location-based ticket books are described. A mobile device can present a virtual ticket to a service provider based on a location of the mobile device. The mobile device can receive a virtual ticket for accessing a service from a service provider. The virtual ticket can be associated with a signal source. The signal source can be pre-programmed to broadcast a beacon signal that includes an identifier identifying the signal source. The signal source can be placed at a venue where the service is available. The mobile device, upon arriving at the venue, can detect the beacon signal from the signal source. In response, the mobile device can activate a ticket manager. The ticket manager can automatically select, from a ticket book, the virtual ticket associated with the signal source. The mobile device can present content of the selected virtual ticket at the venue where the service is available.

Abstract: A system and method of locating “friends” having mobile devices connected to a network and associated with a user account is disclosed. The method includes sending a request to a mobile device, the mobile device determining its present geographic location and responding to the requestor with this information. This information may be in the form of a coordinate location such as a GPS location or it may be in the form of a name that the mobile device owner assigned to a particular area (e.g., “home”). Having this location information, a user is able to view the location of the friend that is associated with the mobile device.

Abstract: Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.

Additionally or alternatively, a transmitter device can reduce a current level received by a DC-to-AC converter if the current received by the DC-to-AC converter equals or exceeds a threshold. Additionally or alternatively, a transmitter device can ping a receiver device and transfer energy only after a response signal is received from the receiver device.
