    摘要: The present invention provides apparatus and methods for attenuating audio based on sensed motion in a predefined area proximate to one or both the user and the audio source. The present invention is particularly useful to users who may startle easily, allowing a user to listen with headphones or earbuds without constantly being concerned that someone is going to “appear out of nowhere” and startle the user. The present invention may also be useful in the event of an emergency, where motion may attenuate the audio and allow a user to be more conscientious of their immediate surroundings.

    摘要: A wireless protocol for a communication system is set forth herein which may be utilized for communication between a transmitter and a receiver over any type of communication channel. The wireless communication protocol provides for the reduction of receiver active or on time which in turn lowers power consumption. The wireless communication protocol enables the complexity and receiver size to be reduced. The methodology employed in the protocol utilizes a unique message frame in conjunction with repeated transmission and periodic receiver searching.
