  • Patent number: 11193783
    Abstract: In device-assisted navigation, audio navigation cues are often presented at particular locations along a route (e.g., “in 200 meters, turn left” and “turn left here”). However, if the user stops, navigation cues also stop since the user's position is not changing. Additionally, the navigation instruction at the next navigation point may be conflated with the actual position of the next navigation point; e.g., an instruction to “turn left” may be confusing if the road takes a sharp right turn immediately before the next navigation point. Instead, the device may periodically compare the current position of the user and the next navigation point, and periodically present guidance audio cues that indicate the distance and heading offset to the next navigation point. Guidance audio cues may be integrated with and/or supplemented by audio navigation instructions to indicate both the location of the next navigation point and instructions to be followed there.

  • Patent number: 10922045
    Abstract: A boat includes a dash positioned proximate a windshield at a first non-zero angle. A speaker is mounted under a top surface of the dash at a second non-zero angle. The speaker is positioned to direct sound emanating from the speaker through an opening in the dash and the windshield is configured to reflect the sound emanating from the speaker as reflected sound in an aft direction. The boat may also include an enclosure having a reflective surface positioned within a cavity formed between the deck and hull of the boat. A speaker, mounted within the enclosure, and the reflective surface are configured to reflect sound emanating from the speaker off of the reflective surface and through an opening of the enclosure.

  • Patent number: 10916257
    Abstract: A method and a device for equalizing audio signals, where the method includes: obtaining an audio signal (S401); acquiring an echo estimate that is caused by a sound reflection off one or more objects (S403); acquiring correction data based on the audio signal and the echo estimate (S405); and equalizing the audio signal based on the correction data (S407). Accordingly, by virtue of the method and the device for equalizing audio signals, equalization can be performed automatically in real time to match an audio signal to a desired reference frequency response with consideration of spatial acoustics, such as indirect echoes.

  • Patent number: 10803849
    Abstract: The present invention provides a sound pressure signal output apparatus capable of synthesizing and outputting a sound pressure signal that simulates the sound of a real engine with reduced processing load in real time while flexibly adapting to specification changes. The sound pressure signal output apparatus comprises: an interface that acquires single sound data corresponding to the sound generated by one cylinder of a vehicle-mounted internal combustion engine during one combustion cycle in the cylinder, acquires order sound data corresponding to order sound for a frequency corresponding to the engine rotation speed, and acquires random sound data generated corresponding to at least either the material or the shape of the structure that makes up an engine; and a synthesis unit that synthesizes and outputs the sound pressure signal of an engine sound using the single sound data and the like acquired.

  • Patent number: 10674267
    Abstract: A method may include monitoring a sensor associated with a first location of an automobile seat, where the first location corresponds to a first transducer embedded within the automobile seat, and the automobile seat includes a second transducer at a second location within the automobile seat. The first and the second transducers may be configured to generate tactile feedback upon receiving an activating signal. The method may also include detecting an event triggering the activating signal to be sent to the first transducer, and based on a reading from the sensor indicating that an occupant of the automobile seat is not in contact with the first location, modifying the activating signal such that the first transducer primarily produces an audible sound rather than tactile feedback.

  • Patent number: 10634554
    Abstract: A vibration data collection system performs an integration or differentiation process on incoming digitized vibration data in real time. The system uses a digital Infinite Impulse Response (IIR) filter running at the input data rate to provide the integration or differentiation function. With this approach, the system reduces hardware complexity and data storage requirements. Also, the system provides the ability to directly integrate or differentiate stored time waveforms without resorting to FFT processing methods.
