Abstract: A voice-activated encoding method includes determining a voice power parameter based on a frequency domain representation of a voice signal from a voice microphone. The method includes determining an ambient power parameter based on a frequency domain representation of at least one ambient signal from at least one ambient microphone spaced from the voice microphone. The method also includes enabling encoding of an audio signal based on the voice signal in response to comparing the power parameters and a threshold value. A headset including a controller may use the method to determine whether to enable or disable encoding, transmission, or both of an audio signal to another device.

Abstract: A system includes an article of personal protective equipment (PPE) including a functionality that is selectively configurable using a subscription service. The system further includes a first computing device including a first processor and a second computing device including a second processor. The first processor generates a subscription message including a request to enable the functionality of the article of PPE in response to determining a selection of the functionality. The second processor determines if credentials corresponding to the article of PPE and/or a user associated with the article of PPE are preregistered with the subscription service. The second processor determines a subscription status of the article of PPE corresponding to the functionality. The second processor transmits a configuration message based on the subscription status and preregistration with the subscription service. The first processor enables the functionality of the article of PPE based at least partly on the configuration message.
