Abstract
An active headworn device that includes a position sensing device used to determine whether the headworn device is in an extended state upon a user's head or in a contracted state off of the user's head. The position sensing device may be coupled with a microcontroller adapted to power up or power down the active headworn device based on a signal from the position sensing device. The position sensing device may various devices such as a Hall-effect device used in combination with a magnet or a LED in combination with a detector. The movement of the headworn device between positions changes the distance between components of the position sensing device such that the device signals the microcontroller to power up or down the active headworn device. The microcontroller may mute a portion of circuitry prior to the powering up or down the active headworn device to prevent undesirable feedback.
