Abstract: A system may determine driving information associated with a group of users, the driving information may be based on sensor information collected by at least two of a group of user devices, a first group of vehicle devices connected to a corresponding group of vehicles associated with the group of users, or a group of second vehicle devices installed in the corresponding group of vehicles.

The method also includes determining surface inclination values based on the accelerometer values. The method further includes storing the surface inclination values. And the method includes applying a digital filter to the stored surface inclination values to determine a final surface inclination value.

The classification model may be transmitted to at least some of the PER devices to update a previous version of the classification model at the at least some of the PER devices.

Abstract: Digital content distribution systems and methods are provided for distributing for digital data files, such as digital audio and video data files. In accordance with one implementation, a token-based authentication system is provided that does not require knowledge of the individual user requesting the download of digital content data or real-time access to user account information. Instead, the token-based authentication system embeds the authentication information, or token, in the download request information itself. In this way, the download or content server authenticates the download request using the token contained in the download request information and therefore does not require any additional information to carry out this authentication, such as access to user account information.
