  • Fully integrated small stereo headset having in-ear ear buds and wireless connectability to audio source
    Patent number: 8498428
    Abstract: A compact, wearable wireless headset for stereo audio reproduction contains first and second ear pieces. The ear pieces each contain a battery and a speaker, and are connected by connecting means. The first ear piece receives audio information via a short range radio, and communicates left channel audio information to the second ear piece by various means, including wirelessly, by wire, and via optical communication. In some embodiments, the battery in the second ear piece supplies power to circuitry located in the first ear piece.

  • Controlling attenuation of an antenna signal in a communication terminal to reestablish a lost communication link
    Patent number: 8005431
    Abstract: Some embodiments of the present invention are directed to methods of operating communication terminals. A wireless communication link is established between first and second communication terminals and communication signals are exchanged therebetween. The first communication terminal is controlled to continue over time to increase a power level at which it transmits communication signals to the second communication terminal in response to detecting loss of the wireless communication link and while continuing attempts to reestablish the communication link with the second communication terminal. The first communication terminal is further controlled, in response to detecting loss of the communication link, to increase a level of attenuation that it applies to communication signals from the second communication terminal, and to then more gradually decrease the level of attenuation over time in response to continuing attempts to reestablish the communication link with the second communication terminal.
