Wireless headset switching system
First Claim
1. A system comprising:
- a mobile communications device;
a wireless headset including a speaker and a microphone, and the wireless headset including an illuminator; and
a switching unit comprising, separate from and detachably coupled to the mobile communications 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 switch coupled to the mobile communications device interface, the wireless headset and the wireless adapter, wherein the switch is configured to automatically implement push-to-talk functionality by selectively connecting signals between the wireless adapter, the wireless headset, and the mobile communications device interface,wherein a trigger signal generated when a signal level associated with the microphone exceeds a predetermined threshold causes the switch to be set to a first position in which a signal captured by the microphone is connected to the mobile communications device interface and a trigger signal generated when the signal level associated with the microphone falls below a predetermined threshold for a predetermined period of time causes the switch to be set to a second position in which a signal captured by the microphone is not connected to the mobile communications device interface and a signal is transmitted from the mobile communication device to the speaker of the wireless headset; and
wherein the illuminator of the wireless headset illuminates upon successful connection between the wireless adapter and the wireless headset, and the illuminator turns off after a set period of time.

Abstract
A wireless headset system including a switching unit having a detection circuit coupled to a wireless adapter. The detection circuit provides a first output signal to the wireless adapter upon detection of a triggering event, such as activation of a manual switch or detection of voltage of an audio output signal from a mobile communications device. The first output signal causes the wireless adapter to enter into an active audio channel mode. The detection circuit also provides a second output signal to the wireless adapter when no triggering event is detected, and the second output signal causes the wireless adapter to enter into a standby mode. Placing at least the wireless adapter in a standby mode saves battery life of the system.
