  • Patent number: 9907078
    Abstract: Method and devices for optimizing wireless network connections in transportation vehicles are provided. An onboard computing device in a transportation vehicle identifies blackout area with severe wireless signal interference caused by nearby wireless access points in the blackout area. The wireless interference can be remedied by dynamically switching wireless channel for the in-vehicle wireless connection between the onboard computing device and a mobile device in the vehicle. The wireless interference can also be remedied by pre-caching the data needed for a content presentation during a time period when the vehicle travels within the blackout area.
    Type: Grant
    Filed: August 3, 2016
    Date of Patent: February 27, 2018
    Assignee: Alpine Electronics of Silicon Valley, Inc.

  • Patent number: 9728187
    Abstract: An on-vehicle device can simultaneously connect smart phones provided with a sound recognition function through short-distance wireless communications. The on-vehicle device determines whether a specific keyword for starting the sound recognition function of the smart phones is included in an utterance sound of a user. When the keyword is included, the on-vehicle device selects the smart phone identified with the keyword, and transmits a sound signal of the utterance sound to the selected smart phone.
