  • the user device 24 provides a headphone jack 56 (Fig. 1), such that the associated user 26 is able to listen to audible media (such as music, for example) via headphones through the user device 24 (524), upon receiving a notification regarding an approaching emergency vehicle 32 within the pre-defined range R (518) and determining the ambient noise level (522), the user device 24 takes into account the volume of audio being provided through the headphone jack 56 (526) when determining whether the ambient noise threshold has been exceeded (528).
  • the user device 24 automatically adjusts (i.e., lowers) the ambient noise threshold to account for the amount of noise suppression (by virtue of physical insulation materials and/or noise cancellation technology) provided by the user vehicle 28 (510).
  • the user 26 is able to manually specify the type (i.e., year, make and model) of user vehicle 28 in which the user device 24 is currently positioned.
  • these noise suppression level details are contained in the database 34 and maintained by the computing system 22.
  • the user device 24 is capable of automatically determining a noise suppression level of the user vehicle 24 and dynamically adjusting the ambient noise threshold to account for the noise suppression level. It should be noted that, in further embodiments, any other method for determining the noise suppression level and adjusting the ambient noise threshold accordingly (either manually or automatically) - now known or later developed - may be substituted.
  • any of these ambient noise thresholds discussed herein may be automatically adjusted by the user device 24 based on that impairment value, in order to better account for the user's 26 hearing loss or impairment.
  • the computing system 22 allows the user 26 to create, store and manage a plurality of ambient noise profiles as part of the associated user account, with each such ambient noise profile related to different environmental scenarios in which the user 26 may typically find themselves, and so each having a particular ambient noise threshold tailored for each such environmental scenario. For example, if the user 26 tends to drive and/or ride in more than one type of user vehicle 28 (with each such user vehicle 28 having a different noise suppression level), the user 26 may create a separate ambient noise profile for each such user vehicle 28 and manually select the appropriate profile as needed. The user 26 may also have a separate ambient noise profile for when the user 26 is a pedestrian. Additionally, each ambient noise profile may also have a different range R - for example, an ambient noise profile for use when the user 26 is a pedestrian may not require as large of a range R as an ambient noise profile for when the user 26 is in a user vehicle 28.
  • the at least one user device 24 provides the associated user 26 with the ability to acknowledge and selectively dismiss a given notification - for example, by providing a button via the GUI on the at least one display screen 44 that may be touched by the user 26 after the notification begins.
  • the at least one user device 24 is configured for only providing notifications when the user device 24 is in motion (530), based on the data provided by the GPS chip 48 of the at least one user device 24 - which would indicate that the associated user 26 is either walking or riding in the user vehicle 28. If the user device 24 is stationary for a pre-defined period of time - which would indicate that the associated user 26 is also stationary and, thus, not likely to encounter an emergency vehicle 32 - the user device 24 does not provide any notifications that it may receive. In at least one such embodiment, the pre-defined period of time is relatively greater than the amount of time the user 24 or user vehicle 28 would typically spend stopped at a stop light or in traffic - such as five minutes, for example.

Abstract

L'invention concerne un système et des procédés pour alerter un utilisateur de la présence d'au moins un véhicule de secours se rapprochant. Dans au moins un mode de réalisation, lorsqu'un véhicule de secours parmi ledit véhicule de secours répond à une situation d'urgence, un état d'urgence du véhicule de secours est transmis à un système informatique central, et une notification est transmise audit dispositif utilisateur sous la commande dudit utilisateur. Lorsque le dispositif utilisateur reçoit ces informations, il est déterminé si le véhicule de secours est à moins d'une distance prédéfinie du dispositif utilisateur, et si un niveau de bruit ambiant dépasse un seuil de bruit ambiant prédéfini. Si tel est le cas, le dispositif utilisateur fournit la notification à l'utilisateur associé.
