    Abstract: A method of operating a media player is provided. In one embodiment the method includes receiving a plurality of initially configured video settings for viewing a video segment on the media player for a desired playback duration. The method further includes determining power required to play the video segment based on the initial video settings and playing the video segment if the required power matches or is less than total power available to the media player. In another embodiment, the method may further include, if the required power exceeds the total power available to the media player, adjusting one or more of the initial video settings, either automatically or by user inputs, to reduce the power required to play the requested video segment for the desired playback duration.

    Abstract: Some embodiments of the present invention provide a system that adaptively charges a battery, wherein the battery is a lithium-ion battery which includes a transport-limiting electrode governed by diffusion, an electrolyte separator and a non-transport-limiting electrode. During operation, the system determines a lithium surface concentration at an interface between the transport-limiting electrode and the electrolyte separator based on a diffusion time for lithium in the transport-limiting electrode. Next, the system calculates a charging current or a charging voltage for the battery based on the determined lithium surface concentration. Finally, the system applies the charging current or the charging voltage to the battery.

    Abstract: Some embodiments of the present invention provide a system that adaptively charges a battery, wherein the battery is a lithium-ion battery which includes a transport-limiting electrode, an electrolyte separator and a non-transport-limiting electrode. To charge the battery, the system first determines a lithium surface concentration at an interface between the transport-limiting electrode and the electrolyte separator. Next, the system uses the determined lithium surface concentration to control a charging process for the battery so that the charging process maintains the lithium surface concentration within set limits.

    Abstract: Electronic devices such as portable electronic devices contain electronic components. The electronic components may include radio-frequency transceiver circuitry. The radio-frequency transceiver circuitry may be used for handling data communications and cellular telephone voice communications. One or more adjustable clock sources may be provided within the electronic device. The adjustable clock sources may be based on phase-locked-loop circuits. A clock manager may determine which frequencies are being used by the radio-frequency transceiver circuitry and other components in the electronic device. The clock manager may use this information to compute a list of safe fundamental clock signal frequencies. Based on the list of safe clock signal frequencies, the clock manager may dynamically adjust the clock sources to avoid collisions between harmonics of the clock signals from the clock sources and the frequencies used by the transceiver circuitry and other components.
