Abstract: Blind spot detection based on audio signals is described. A detection method includes training an engine sound detection machine learning model from motorcycle engine sounds collected under a variety of conditions using an array of microphones configured on a helmet during operation of a vehicle, extracting and recognizing in real-time, using the trained engine sound detection machine learning model, an engine sound from other sounds collected by the array of microphones when the helmet is used during operation of the vehicle, separating direct engine sounds from potential reflected signals to estimate distance and direction to potential objects associated with the potential reflected signals, and providing alerts via the helmet upon detection of an object in a blind spot of the vehicle based on the estimated distance and direction to the potential objects.

Abstract: The present disclosure relates to methods and systems for providing alerts to a helmet user. A method includes determining a current location of the user, determining a transit area and a transit direction of the user based on the current location, retrieving records of transit alerts based on the transit area of the user, selecting relevant transit alerts from the records of transit alerts based on the transit direction of the user, and alerting the user of the relevant transit alerts.

Abstract: A visual communication module includes a light bar configured to be disposed along a periphery of an eyeport of a helmet such that light emitted by the light bar is visible in a peripheral field of view of a user of the helmet; a communication interface configured to receive situational data from one or more sources related to riding/driving guidance for the user of the helmet; and a processing module configured to process the situational data and control the light bar to generate a riding/driving cue. The riding/driving cue comprises an emitted light sequence that extends along the light bar and includes one or more colors of light and a transition pattern progressing along a lateral direction of the light bar.

Abstract: The present disclosure relates to a helmet including a shell, a housing comprising a front panel and a rear panel that form a chin portion of the shell, an electronic board disposed within the housing, a battery disposed within the housing and coupled to the electronic board, a camera disposed within the housing and coupled to the electronic board and the battery. The camera comprises a lens that extends through the front panel of the housing. The housing is embedded within an external profile shape of the helmet.
