    Abstract: Systems (100) and methods (400) for extending battery life on a Communication Device (“CD”). The methods involve: configuring operations of CD and an accessory such that they operate in a first operational mode in which the accessory has a first functionality; and detecting the occurrence of a trigger event. The trigger event occurs when: (a) CD's power source has a State-Of-Charge (“SOC”), capacity or voltage level that is not optimal for powering the accessory, (b) a voltage level of the accessory's power source is below a lowest voltage level at which the accessory can fully operate, or (c) a power source of the accessory is sufficiently charged/re-charged such that the accessory can once again operate in the SOM. In response to the trigger event, operations of CD and accessory are re-configured such that they operate in accordance with a second operational mode in which the accessory has a second functionality.

    Abstract: A system and method to determine a power-up parameter for a circuit board. The method includes electrically exciting a second-order circuit to generate an underdamped transient response. The method includes receiving, at a comparator coupled to the second-order circuit, the underdamped transient response. The method includes generating, in response to the underdamped transient response received at the comparator, a plurality of edges. The method includes receiving, at a single general purpose input/output pin of the electronic processor, the plurality of edges. The method includes determining a first response parameter based on a plurality of edges. The method includes determining a second response parameter based on the plurality of edges. The method includes determining the power-up parameter based on the first response parameter and the second response parameter.
