Patent ID: 8644888

Claim:
A system comprising: a mobile communications device; a wireless headset including a speaker and a microphone; and a switching unit comprising, separate from and detachably coupled to the mobile communication device through a cabled connection, the switching unit comprising: a mobile communications device interface for transmitting signals to and receiving signals from the mobile communications device; a wireless adapter for transmitting signals to and receiving signals from the wireless headset; and a detection circuit coupled to the wireless adapter, the detection circuit provides a first output signal to the wireless adapter upon detection of a triggering event, the first output signal causes the wireless adapter to enter into an active audio channel mode, and the detection circuit provides a second output signal to the wireless adapter when no triggering event is detected, the second output signal causes the wireless adapter to enter into a standby mode; wherein the detection circuit is in connection with the wireless adapter and the mobile communications device interface, the triggering event is a signal created by audio output of the mobile communications device, and the detection circuit sends the first output signal to the wireless adapter when voltage of the signal created by audio output from the mobile communications device is detected by the detection circuit, which places the wireless adapter in the active audio channel mode.
