  • Publication number: 20130136272
    Abstract: A computer-implemented method and system allows a remote computer user to listen to teams in a race event. The method includes receiving audio signals from a plurality of audio sources at the race event; transmitting at least some of the audio signals to a remote computer; and filtering the audio signals as a function of the source of at least some of the audio signals so that at least some of the audio signals are not played by the remote computer and heard by the user.
    Type: Application

  • Patent number: 8062804
    Abstract: A flow control assembly for use in a fuel cell system, comprising a sensor for sensing hydrogen concentration in one of anode exhaust leaving an anode side of the fuel cell system and a gas derived from the anode exhaust, and a fuel flow control assembly for controlling the flow of fuel to the anode side of the fuel cell system based on the hydrogen concentration sensed by the sensor.
    Type: Grant
