Abstract: Systems and methods for adjusting pitch of an audio signal include detecting input notes in the audio signal, mapping the input notes to corresponding output notes, each output note having an associated upper note boundary and lower note boundary, and modifying at least one of the upper note boundary and the lower note boundary of at least one output note in response to previously received input notes. Pitch of the input notes may be shifted to match an associated pitch of corresponding output notes. Delay of the pitch shifting process may be dynamically adjusted based on detected stability of the input notes.

Abstract: A roadway projection system integrated into a vehicle is configured to identify a specific driving scenario encountered by a driver of the vehicle, and to then project an image onto a roadway along which the vehicle travels based on that scenario. The image is intended to provide guidance to the driver in negotiating the identified scenario and/or to visualize potential driving actions of the driver for the benefit of others. The image could be, for example, and without limitation, an indicator that the driver should follow to perform a specific driving or navigation action, or a preference that the driver wishes to share with other drivers. In addition, the roadway projection system may detect images projected by other roadway projection systems in other vehicles and to determine mutual preferences shared between drivers. When a shared preference is violated, the roadway projection system may alert the driver of the vehicle.

Abstract: A system, and method for communicating navigation information to a vehicle operator through actuators in a steering mechanism for a vehicle. The steering mechanism can include multiple actuators along or in a surface a vehicle operator touches to steer the vehicle. Different numbers of actuators can be actuated under an operator's hand to communicate the severity of an upcoming turn. Alternatively, an actuator can be actuated by different amounts to communicate the severity of an upcoming turn. Proximity of an upcoming turn can be communicated by cycling actuators at different rates for different turns. By actuating actuators under an operator's left hand or the left portion of a hand, a left-hand turn can be communicated. Conversely, by actuating actuators under an operator's right hand or the right portion of a hand, a right-hand turn can be communicated.

Abstract: A navigation system is configured to plot a route through a shopping area that visits various stores offering specific types of promotions. A user of the navigation system first selects a desired promotion, including a discount level, among other possibilities. Then, the user selects a category of store where the user wishes to shop. The navigation system then identifies nearby stores offering the desired promotion that fall within the selected category, and plots a route that visits each identified store. The route may traverse from the current location of the user to a final destination, or may represent a circuit with collocated starting and ending positions.

Abstract: A navigation system is configured to generate a sequence of driving instructions for directing a driver of a vehicle from a current location to a final destination. The navigation system is configured to capture sensor data that reflects the field of view of the driver and to identify objects in that field of view.
