Abstract: Methods and apparatus are provided for timeshifting audio content in a multiple tuner audio system comprising a first tuner and a second tuner. One operating method involves maintaining a first data storage element for the first tuner, maintaining a second data storage element for the second tuner, receiving first audio content in realtime by the first tuner, and storing data representing the first audio content in the first data storage element, resulting in first stored content. The method also receives second audio content in realtime by the second tuner, and stores data representing the second audio content in the second data storage element, resulting in second stored content. The method thereafter generates a timeshifted audio signal corresponding to the first stored content or the second stored content.

Abstract: An apparatus and method are disclosed for real-time assessment of driver workload by a vehicle device. To determine driver workload, the system monitors the driver interaction with the vehicle device. The driver interaction is then used to determine an estimated driver workload based on the driver interaction. In one embodiment, the vehicle device has one or more buttons configured to be pressed by the driver and each of the one or more buttons has an assigned driver workload value. The system sums the workload value of the buttons pressed by the driver over a moving time window to determine the estimated driver workload.

Abstract: A vehicular navigation system includes a display, a memory configured to store data related to a plurality of preset map view, and a user input configured to permit the selection of a map view from the plurality of preset map views. A controller is coupled to the user input, the display, and the memory. The controller is configured to generate the selected map view on the display.

Abstract: Methods and apparatus are provided for adaptively locking out a display on a vehicle device based on user interaction. A method begins by counting a number of user initiated display changes with an event counter, and timing the user initiated display changes with an event timer. The method continues by comparing the number of user initiated display changes in the event counter to an allowable number of user initiated display changes corresponding to the time in the event timer, and disabling the display for a display lockout time period if the number of user initiated display changes exceeds the allowable number of user initiated display changes.
