Abstract: A loudspeaker configured to provide asymmetrical beam coverage. A first group of drivers to outputs a first beam pattern. A second group of drivers, which is different from the first group of drivers, is configured to output a second beam pattern. A transmission line is adapted to output signals to the first driver group and the second driver group to provide an asymmetrical beam pattern. The first driver group outputs a beam pattern different than the second driver group. This can improve acoustic coverage, e.g., sound pressure levels, in the acoustic environment. In an example, the transmission line is separated into two distinct parts that feeds the first driver group and the second driver group respectively.

Abstract: A pedestrian information system that can provide alerts to a distracted pedestrian related to hazards in the pedestrian's path. The system can detect objects, and determine if the objects are hazardous and if the pedestrian is likely to collide with the objects. The system can then determine from the pedestrian's activity whether the pedestrian is aware of identified hazards. If the system determines that the pedestrian is not aware of the identified hazards, then the system can output audio, visual, and/or haptic alerts to the pedestrian.

Abstract: In one embodiment, a healing engine included in an audio system enables the audio system to perform self-repair operations. Upon detecting that an audio device included in the audio system has failed, the healing engine executes repair operations. First, the healing engine identifies any new audio devices added to the audio system after the failed audio device failed. The healing engine then selects one of the new audio devices as a replacement for the failed audio device. Finally, the healing engine configures the selected audio device to implement a system identity that previously identified the failed audio device with respect to the audio system. In this fashion, the healing engine replaces the failed audio device with the selected audio device. By automating the repair process, the healing engine reduces the time and effort required to restore the audio system to a fully operational state compared to conventional, manually-based techniques.

Abstract: A sound enhancement system (SES) that can enhance reproduction of sound emitted by headphones and other sound systems is disclosed. The SES improves sound reproduction by simulating a desired sound system without including unwanted artifacts typically associated with simulations of sound systems. The SES facilitates such improvements by transforming sound system outputs through a set of one or more binaural rendering filters derived from direct and indirect head-related transfer functions (HRTFs). Parameters of the binaural rendering filters are updated based on the head tracking angle of user wearing the headphones to render a stable stereo sound image. The head tracking angle may be determined from sensor data obtained from a digital gyroscope mounted in a headphone assembly.
