International ClassesH04B 1/38H04M 1/00 AbstractA wireless headset for use with a separate communications device, such as a cellular telephone, includes automatic on/off capabilities to maximize battery life. By detecting a user's interaction, such as picking up the headset or placing it upon the user's body, the wireless headset automatically transitions from an inactive state to an active state. Techniques for automatic headset enabling include but are not limited to motion sensors, attitude or position sensors, proximity sensors, and contact sensors. These techniques may be used individually or in any combination. An internal timer allows the wireless headset to return to its inactive state a defined interval after cessation of movement or removal of the wireless headset. Including an optional sleep state further optimizes battery life. In the sleep state, only a portion of the wireless headset circuitry is enabled. Rather than transitioning from inactive to active, the headset transitions from inactive to sleep. In sleep, the headset periodically monitors for a signal from the separate communications device. Upon detection of such a signal, the wireless headset transitions to its active state, thereby providing full functionality to the user.Other References
