Abstract From the Canadian patent

An audio system for a vehicle that includes a system for allowing an occupant of the vehicle to adjust a balance setting of each audio source (116). The audio system includes a plurality of audio sources (102) that are connected to an amplifier (104). The amplifier is connected to a head unit (106) that adjusts the balance setting of each audio source based on predetermined parameters or user preferences (112). Audio output signals from the audio sources are thus reproduced with different balance settings.

Why it's free to use

  • Filed January 23, 2003 and granted June 17, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 23, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 23, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
