Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. A power management component in a system may be configured to obtain measurements associated with a signal path used for communication by the system via a communication port, and manage power use in the system based on the obtained measurement. Managing the power use may include determining, based on the obtained measurements, connectivity related information associated with connectivity of the system via the communication port, and applying based on the information one or more power use reduction measures, with the one or more power use reduction measures including at least transitioning between different power related states.

A method of a wearable device displaying icons is provided. The method includes displaying a plurality of circular icons comprising a first circular icon located in a center area of a touch display in a first size and a second circular icon located outside of the center area of the touch display in a second size smaller than the first size, and based on a direction of a touch input received on the touch display, moving the plurality of circular icons such that the first circular icon is moved to a first position located outside of the center area of the touch display and the second circular icon is moved from a second position located outside the center area of the touch display to the center area of the touch display and enlarged in size from the second size to the first size.

Techniques are described for managing temperature in an autonomous vehicle. An exemplary method comprises performing autonomous driving operations that operate the autonomous vehicle in an autonomous mode, receiving one or more messages from a temperature sensor associated with an electrical device located on or in the autonomous vehicle while the autonomous vehicle is operated in the autonomous mode, determining a cooling technique to reduce the temperature of electrical device, and performing the cooling technique.

Processor-based systems employing local dynamic power management based on controlling performance and operating power consumption, and related methods. The processor-based system is configured to locally manage its power consumption by dynamically adjusting operating frequency and/or operating voltage of power supplied to the processor-based system. The processor-based system includes a power control circuit that is aware of the overall power budget for the processor-based system. The control processor in the processor-based system can dynamically increase the voltage level of the power supplied to the processor-based system and/or the operating frequency if the consumed power is lower than the power budget. The power control circuit can also dynamically decrease the operating frequency and/or the voltage level of the power supplied to the processor-based system if the consumed power is higher than the power budget.

Systems and methods for maintaining knowledge of a network address (e.g., a MAC address) for a playback device while changing power states are disclosed. In one embodiment, a method for maintaining knowledge of the network identity of a playback device while changing power states includes determining that a playback device is entering a sleep state, sending state information from the playback device to a central data repository over a network responsive to the determination that the playback device is entering sleep state, where state information includes a MAC address, receiving the state information about the playback device at a waking device from the central data repository, waking the playback device periodically at predetermined time intervals while in sleep state to listen for messages addressed to the MAC address, and receiving a wake-up message at the playback device from the waking device and responding by changing from sleep to active state.

Methods and apparatus relating to platform power consumption reduction via power state switching are described. In one embodiment, control logic causes a processor to enter a first low power consumption state (e.g., S0ix) instead of a second low power consumption state (e.g., S3) based on whether a threshold time period exists between a first wake event (e.g., corresponding to a first one of one or more awake requests) and a second wake event (e.g., corresponding to a second one of the one or more awake requests). Other embodiments are also claimed and disclosed.
