Abstract: A method is disclosed for sensing, reporting, and correcting microphone proximity for a headset. The method includes determining a current proximity of a headset microphone to a face of a user. The method also includes storing the current proximity of the headset microphone as a calibrated microphone proximity value, and selecting, based on the calibrated microphone proximity value, a range of microphone proximities. Further, the method includes sensing a new proximity of the headset microphone, and comparing the new proximity of the headset microphone with the range of microphone proximities. Still yet, the method includes generating a message for the user in response to determining, based on the comparison, that the new proximity of the headset microphone is outside the range of microphone proximities.

Abstract: A method for real time digital instant messaging includes monitoring a condition of a wireless headset, estimating a potential for the user to receive and immediately respond to a real time digital message, such as an instant communications or a VoIP message, and then selectively directing a real time digital message, when received, to the user via the headset when the estimated potential indicates that the user is reasonably likely to immediately respond to the real time digital message. A sensor in the headset may be used to determine if a recent action of the user was don the headset by putting it on, doff the headset by taking it off, dock the headset by placing it in a charging station, move while wearing the headset, leave the headset on a desktop or other surface or carry the headset.

Abstract: A touch activated control useful for incorporation into, e.g., a DON/DOFF sensor of a communications headset or a touch pad for a cell phone, includes a weakly conductive electrode and a sensor coupled to the electrode and operative to detect a change in parasitic capacitance caused by a change in the proximity of a body to the electrode. The electrode may include a covering made of a weakly conductive material. The weakly conductive property of the electrode enables the prevention of undesirable electrostatic discharge (ESD), user skin irritation and electrode corrosion caused by direct contact between the electrode and the user's skin and also exhibit's a substantially higher sensitivity than electrodes covered with an insulative material.
