System and method for solar keyboard power management

摘要

A method for determining a power sustainability status of a device having one or more solar panels and a battery includes receiving a request to indicate the power sustainability status, measuring a voltage of the battery, and determining a usage level of the device and a low power sustainability threshold. The method further includes computing a remaining capacity of the battery using the voltage of the battery and usage level of the device and computing a light exposure level associated with the one or more solar panels. Additionally, the method includes determining a power sustainability index using at least one of the remaining capacity of the battery or the light exposure level and comparing the power sustainability index to the low power sustainability threshold.

1. A method of indicating a power sustainability status of a device having a processor, a timer, one or more solar panels, and a battery, the method comprising:
generating, using the timer, a trigger at a particular time interval; and in response to at least the trigger:
measuring a voltage of the battery;computing, by the processor, a remaining capacity of the battery using the voltage of the battery;computing, by the processor, a light exposure level associated with the one or more solar panels;determining a power sustainability index using at least one of the remaining capacity of the battery or the light exposure level;determining the power sustainability status based on the power sustainability index; andproviding an indication of low power sustainability status,
wherein when the power sustainability index is determined to be less than or equal to a first low power sustainability threshold, providing an indication that the power sustainability status of the device is in a low sustainability state, andwherein when the power sustainability index is determined to be less than or equal to a second low power sustainability threshold that is less than the first low sustainability threshold, disabling transmission of character data to an external processor device.
