Abstract: A system and method for controlling battery conditions. The system includes a network access device battery. The network access device battery powers a network access device. A heating element may be connected to the network access device battery. The heating element may be a resistive load for determining a status of the network access device battery or the heating element may be activated based on a heating schedule.

Abstract: Methods and systems for masking audio noise are disclosed. One apparatus includes a silence detector configured to detect a period of substantial silence in an audio signal; a masking noise source operably coupled to the silence detector, the masking noise source configured to generate a noise signal in response to the silence detector detecting the period of substantial silence; and at least one combining device operably coupled to the masking noise source, the at least one combining device configured to contribute to combining the audio signal and the noise signal. A method includes detecting a period of substantial silence in an audio signal; and combining masking noise with the audio signal during the period of substantial silence.

Abstract: Methods and systems for analyzing communication options, including determining one or more states of one or more communication-related conditions, and analyzing the one or more states and one or more communication options to determine an optimum communication option.
