Capacitive data transfer through a user's body

摘要

A wireless communications device (20) includes a Personal Area Network (PAN) transceiver (40) that communicates data with a corresponding PAN transceiver (70) disposed in a hands-free visor (50). The device (20) also includes a short-range transceiver (32) that communicates with a corresponding short-range transceiver (62) in the hands-free visor (50). Both the wireless communications device (20) and the hands-free device (50) are configured to select which of these transceivers it is to use to transmit data based on predefined criteria.
