Abstract
A wireless communications device includes a Personal Area Network (PAN) transceiver that communicates data with a corresponding PAN transceiver disposed in a hands-free visor. The device also includes a short-range transceiver that communicates with a corresponding short-range transceiver in the hands-free visor. Both the wireless communications device and the hands-free device are configured to select which of these transceivers it is to use to transmit data based on predefined criteria.
Claims18
A method for communicating data between a user's wireless communication device and a hands-free visor, the method comprising:
- establishing a Personal Area Network (PAN) between a user's wireless communication device and a hands-free visor, the PAN comprising a bi-directional communication link through the user's body;
- establishing a short-range communications link between the wireless communication device and the hands-free visor;
- and
- selectively transmitting the data to the hands-free visor via one of the PAN and the short-range communications link based on at least one of:
- a comparison between a rate at which the data is to be transmitted to the hands-free visor and a predetermined bit-rate threshold;
- and
- a comparison between a current transmit power level for the wireless communications device and a predetermined power level threshold.
A wireless communication device comprising:
- a Personal Area Network (PAN) transceiver;
- a short-range transceiver;
- and
- a controller configured to:
- establish a bi-directional communication link through a user's body with a corresponding PAN transceiver at the hands-free visor;
- establish a short-range air-interface link with a corresponding short-range transceiver disposed in the hands-free visor;
- and
- selectively transmit the data to the hands-free visor via one of the PAN and the short-range air-interface link based on at least one of:
- a comparison between a rate at which the data is to be transmitted to the hands-free visor and a predetermined bit-rate threshold;
- and
- a comparison between a current transmit power level for the wireless communications device and a predetermined power level threshold.
A method for communicating data between a user's wireless communication device and a hands-free visor, the method comprising:
- establishing a Personal Area Network (PAN) between a user's wireless communication device and a hands-free visor, the PAN comprising a bi-directional communication link through the user's body;
- establishing a short-range communications link between the wireless communication device and the hands-free visor;
- and
- selectively transmitting the data to the wireless communication device via one of the PAN and the short-range communications link based on at least one of:
- a comparison between a rate at which the data is to be transmitted to the wireless communication device and a predetermined bit-rate threshold;
- and
- a comparison between a current transmit power level for the hands-free visor and a predetermined power level threshold.
A hands-free visor accessory device for a wireless communication device, the accessory device comprising:
- a Personal Area Network (PAN) transceiver;
- a short-range transceiver;
- and
- a controller configured to:
- establish a bi-directional communication link through a user's body with a corresponding PAN transceiver at the wireless communications device;
- establish a short-range air-interface link with a corresponding short-range transceiver at the wireless communications device;
- and
- selectively transmit the data to the wireless communications device via one of the PAN and the short-range air-interface link based on at least one of:
- a comparison between a rate at which the data is to be transmitted to the wireless communications device and a predetermined bit-rate threshold;
- and
- a comparison between a current transmit power level for the accessory device and a predetermined power level threshold.
