Abstract: A wearable communication apparatus is in the form of a self-contained telephone headset that includes an integral antenna, stand-alone power supply and on-board electronics and circuitry for RF and I/R communication. The headset includes a mouthpiece that is rotatably mounted to a central housing that contains the bulk of the apparatus electronics. The mouthpiece includes an ear speaker and microphone, as well as the rechargeable power supply. The rotating end of the mouthpiece includes an array of electrical contacts that are configured to contact a complementary contact array on the central housing. The electrical contacts provide for the communication of electrical power and information between the mouthpiece and its components and the central housing and its components. The headset can be activated by rotation of the mouthpiece into its operative position and deactivated by rotation out of this position.
