  • Patent number: 9825355
    Abstract: A first electronic device uses a first wireless link to connect wirelessly to an audio source device, and a second wireless link to connect to a second electronic device. In some cases, the first electronic device and the second electronic device can be worn by, or mounted to, a user. Upon receiving audio from the audio source device, the first electronic device extracts stereo channels from the received audio, and transmits at least one of the channels to the second electronic device. In some embodiments, an antenna of the first electronic device and an antenna of the second electronic device create a coaxial antenna pair. Alternately or additionally, each antenna, when worn by or mounted to a user, propagates an electric field in a direction generally normal to the user's head. In turn, this generates a creeping wave that travels along a surface, such as the surface of the user's head.

    Abstract: A method and a wireless device (120, 122) utilize auxiliary information associated with an emergency alert system alert message to direct a user of the wireless device (120, 122) to safety. A wireless communication system (102) wirelessly transmits an emergency alert system (EAS) alert message to a wireless device (120, 122). The wireless communication system (102) also wirelessly transmits an augmented EAS alert message to the wireless device (120, 122). The augmented EAS alert message includes auxiliary information that provides information to the wireless device (120, 122) to direct a user of the wireless device (120, 122) to move at least one of toward a safe zone (150) and away from a danger zone (158). The auxiliary information in the augmented EAS alert message is optionally adjusted based on any combination of: the location of the wireless device, the safe zone, and the danger zone, and the logistics of a vicinity affected by the danger zone.

  • Patent number: 7796948
    Abstract: Performance of a radio device is optimized by estimating if the device is inside a building. One or more sensors on the radio device are used to measure an environmental quantities relating to the environment of the radio device. The likelihood of the radio device being inside a building is inferred from these measurements. The operation of the radio device then is controlled accordingly. For example, if the radio device is determined to be inside a building, a low operating frequency may be selected for the radio device if a wide area network connection is required, while a high operating frequency may be selected if a local connection is required. An environmental quantity may be, for example, a satellite signal, ambient light, temperature, RF energy, or the response to a test signal emitted by the radio device.

  • Publication number: 20090138831
    Abstract: A user interface (210) includes an RC circuit (213). The RC circuit (213) includes a variable capacitance. The variable capacitance is produced by a sensing member (310) in cooperation with a user's finger (311). When a user makes a selection with the user interface (210), the user places a finger (311) in close proximity and in a facing relationship to a section, or discrete surface (320, 322, 324), of the sensing member (310). The discrete surfaces (320, 322, 324) can correspond to keys of a keypad (138) or to directions of a directional button (1030), for example. The time constant of the RC circuit (213) varies according to which discrete surface (320, 322, 324) is determining the capacitance of the RC circuit (213). A controller (118) determines the user's selection based on the time constant of the RC circuit (213).
