Abstract
This disclosure provides a method and apparatus for saving and restoring state information of a wireless device with varying amounts of available power, such as wireless devices that may harvest power from radio-frequency signals. The wireless device may save and restore varying amounts of state information based at least in part on the amount of power available. In some embodiments, some of the stored state information may be lost as the available power decreases.
Claims17
A method for saving and restoring state information of a wireless device, the method performed by the wireless device and comprising:
- storing, in a memory of the wireless device, state information associated with one or more operations performed by the wireless device;
- powering down at least part of the wireless device;
- determining an amount of available power of the wireless device;
- selecting one or more operations to restore in response to the determined amount of available power being less than a threshold amount of available power, wherein comprise fewer than all available operations to restore;
- and
- restoring the state information of the one or more selected operations from the memory.
A wireless device comprising:
- an energy harvester configured to convert radio-frequency (RF) energy into power for the wireless device;
- one or more processors;
- and
- a memory configured to store instructions that, when executed by the one or more processors, cause the wireless device to:
- store state information associated with one or more operations performed by the wireless device;
- power down at least part of the wireless device;
- determine an amount of available power of the wireless device;
- select one or more operations to restore in response to the determined amount of available power being less than a threshold amount of available power, wherein the one or more operation comprise fewer than all available operations to restore;
- and
- restore the state information of the selected operations.
An apparatus comprising:
- means for converting radio-frequency (RF) energy into power for the apparatus;
- means for storing state information associated with one or more operations performed by the apparatus;
- means for powering down at least part of the apparatus;
- means for determining an amount of available power of the apparatus;
- means for selecting one or more operations to restore in response to the determined amount of available power being less than a threshold amount of available power, wherein the one or more operations comprise fewer than all available operations to restore;
- and
- means for restoring the state information of the one or more selected operations.
